RESUMO

INTRODUCTION: Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic renal inflammation, caused by long-term obstruction of the urinary tract. Pyonephrosis is a severe suppurative complication of acute obstructive pyelonephritis. Although minimally invasive approaches have many advantages, the safe dissection of the kidney may not be always achievable. MATERIALS AND METHODS: We reviewed 27 cases diagnosed with either XGPN or pyonephrosis, who underwent laparoscopic total nephrectomy between October 2016 and March 2022 in our department. All interventions were performed using the Karl Storz 3D laparoscopic system. The surgical approach was standard transperitoneal nephrectomy for the majority of XGPN, while pyonephrosis cases were carried out in a retroperitoneally. All procedures were performed or supervised by the same surgeon. RESULTS: The mean operative time was 269.85 minutes (range 145-360). The mean hemoglobin drop after surgery was 1.41 g/dl (range 0.3-2.3 g/dl). Difficult dissection was encountered in 13 cases (48.14%). Nine out of 13 interventions were carried out in a complete intracorporeal fashion, while conversion to open surgery was needed in 4 cases. Vascular complications involving the major blood vessels comprised of one case of inferior vena cava (IVC) tear. Digestive tract-related complications comprised two fistulas of the descending colon and one peritoneal breach. Multiorgan resection was performed in 6 cases. CONCLUSION: Total nephrectomy in cases of XGPN and pyonephrosis is a challenging procedure. The laparoscopic approach is feasible, as most complications are resolved intracorporeally. However, it may remain reserved for large-volume centers with experienced surgeons.

RESUMO

OBJECTIVES: The objective of this study is predict positive surgical margin (PSM) and pathological T3a (pT3a) upstaging in patients with clinical T1 (cT1) renal cell carcinoma (RCC). MATERIALS AND METHODS: 159 patients who underwent radical nephrectomy (RN) or partial nephrectomy (PN) for RCC. Patients' demographic, laboratory, radiological and pathological data that could predict PSM and pT3a upstaging pre-operatively were evaluated. The categorical and continuous variables were compared between the patient groups with or without PSM and/or pT3a upstaging using Pearson's chi-square test, and independent samples t-test or the Mann-Whitney U test, respectively. RESULTS: PT3a upstaging was detected in 32 (20.1%) patients, and PSM was detected in 28 (17.6%) patients. PT3a upstaging was detected in 27 and 5 patients who underwent open surgery and laparoscopic surgery, respectively (P < .001). In addition, pT3a upstaging was detected in 6 and 26 patients who underwent RN and PN, respectively (P < .001). Peritumoral fatty tissue thickness was 11.97 and 15.38 in the pT1 and pT3a patient groups, respectively (P = .022). In patients with pT3a upstaging, tumor size was larger, and renal nephrometry score and systemic immune-inflammation index (SII) were higher (P < .001, P < .001, and P = .022, respectively). It was determined that De Ritis ratio (DRR) and albumin-to-alkaline phosphatase (ALP) ratio (AAPR) parameters had significant prognostic values in predicting PSM (P = .024, and P = .001, respectively). ROC analysis indicated that tumor size predicted pT3a upstaging with 100% sensitivity and 98.6% specificity when its cut-off value was taken as 6.85 mm (AUC: 1.000, P < .001). In addition, logistic regression analysis revealed AAPR and DRR as significant predictors of PSM (P < .001, and P = .009, repsectively). CONCLUSION: The findings of this study indicated that the surgical technique of choice and the type of operation, tumor size, RNS value, peritumoral fatty tissue thickness, HU values of peritumoral and tumor side fatty tissues, and DRR and SII values can predict pT3a upstaging of patients with cT1 RCC, and that AAPR and DRR values can predict PSM.

RESUMO

Introducción: Los receptores de trasplante renal (TR) tienen al menos cuatro veces más riesgo de desarrollar neoplasias renales que la población general. Dado que estos pacientes suelen albergar tumores bilaterales o multifocales, el tratamiento de las masas renales sigue siendo un tema controvertido. Objetivo Explorar el tratamiento actual de las masas renales en riñones nativos de pacientes con TR. Adquisición de la evidencia Se realizó una búsqueda bibliográfica en la base de datos Medline/PubMed y se incluyeron 34 estudios en la presente revisión. Síntesis de la evidencia La vigilancia activa es una opción terapéutica factible en pacientes frágiles con masas renales menores de 3 cm. Dado que la cirugía conservadora de nefronas no está justificada en el caso de masas en el riñón nativo, la nefrectomía radical es el tratamiento estándar para los tumores renales en riñones nativos de receptores de TR, con técnicas laparoscópicas asociadas a tasas de complicaciones perioperatorias significativamente menores en comparación con el abordaje abierto. La realización de nefrectomía bilateral de riñón nativo y TR en el mismo acto puede ser una opción terapéutica en pacientes con masa renal y enfermedad poliquística renal, particularmente ante la ausencia de diuresis residual. Los pacientes con enfermedad localizada y nefrectomía radical satisfactoria no requieren ajuste del tratamiento inmunosupresor. En los casos con metástasis, los agentes mTOR pueden garantizar una respuesta antitumoral eficaz, manteniendo a la vez el tratamiento inmunosupresor adecuado para proteger el injerto. Conclusiones El cáncer renal en riñones nativos postrasplante es un acontecimiento frecuente. La nefrectomía radical es el tratamiento de elección en masas renales localizadas. Aún no se ha implementado una estrategia de cribado estandarizada y ampliamente aprobada para las neoplasias malignas en las unidades renales nativas. (AU)


Introduction: Kidney transplant (KT) recipients have a four-times higher risk of renal malignancies compared to general population. As these patients frequently harbor bilateral or multifocal tumors, the management of renal masses is still under debate. Objective To explore the current management of the native kidney masses in KT patients.Acquisition of evidenceWe performed a literature search on MEDLINE/PubMed database. A number of 34 studies were included in the present review. Synthesis of evidence In frail patients with renal masses below 3 cm, active surveillance is a feasible alternative. Nephron-sparing surgery is not justified for masses in the native kidney. Radical nephrectomy is the standard treatment for post-transplant renal tumors of the native kidneys in KT recipients, with laparoscopic techniques leading to significantly less perioperative complication rates as compared to the open approach. Concurrent bilateral native nephrectomy at the time of transplantation can be considered in patients with renal mass and polycystic kidney disease, especially if no residual urinary output is present. Patients with localized disease and successful radical nephrectomy do not require immunosuppression adjustment. In metastatic cases, mTOR agents can ensure efficient antitumoral response, while maintaining proper immunosuppression in order to protect the graft. Conclusions Post-transplant renal cancer of the native kidneys is a frequent occurrence. Radical nephrectomy is most frequently performed for localized renal masses. A standardized and widely-approved screening strategy for malignancies of native renal units is yet to be implemented. (AU)

RESUMO

Introducción. El trasplante es la mejor opción de tratamiento para los pacientes con enfermedad renal terminal, sin embargo, existe discrepancia entre las listas de espera y la disponibilidad de órganos a partir de la donación cadavérica. Buscando aumentar el número de órganos disponibles se implementó el trasplante con donante vivo. A partir de la introducción de técnicas mínimamente invasivas para la nefrectomía, el donante vivo ha logrado cifras cercanas al 50 % de los trasplantes realizados en muchas instituciones, debido a los beneficios propios del procedimiento. El objetivo de este estudio fue describir los resultados después de la incorporación del procedimiento totalmente laparoscópico en nuestra institución. Métodos. Se hizo un análisis retrospectivo de las características de los pacientes llevados a nefrectomía para obtención de injerto por técnica totalmente laparoscópica y los resultados en un solo centro en Cali, Colombia, desde noviembre de 2019 hasta octubre de 2022. Los datos fueron obtenidos mediante la revisión de las historias clínicas electrónicas. Resultados. Se realizaron 78 nefrectomías para obtención de injerto con técnica totalmente laparoscópica. El tiempo operatorio promedio fue de 152 minutos, el sangrado promedio fue de 12 ml, la estancia hospitalaria promedio del donante fue de 2,8 días. La tasa de complicaciones fue de 7,6 % (4 pacientes con complicación Clavien-Dindo I y 2 pacientes Clavien-Dindo IIIb). No se presentó ningún caso de mortalidad. Conclusiones. La técnica totalmente laparoscópica resulta ser una técnica segura con baja tasa de morbilidad y excelentes beneficios para los donantes.


Introduction. Kidney transplant is the best treatment option for end-stage renal disease. However, the discrepancy between waiting lists and the availability of organs from cadaveric donation is well known. Organ transplantation with a living donor was implemented to increase the number of organs available. Since the introduction of minimally invasive techniques for nephrectomy, living donors have achieved figures close to 50% of transplants performed in many institutions due to the procedure's benefits. In our country, the experiences described are from the hand-assisted technique. This is the first description after incorporating the laparoscopic procedure. Methods. A retrospective analysis of the characteristics and results of all patients undergoing nephrectomy to obtain a graft using a laparoscopic technique was carried at a single center in Cali, Colombia, from November 2019 to October 2022. The electronic medical records were reviewed to obtain the data. Results. Seventy-eight nephrectomies were performed to obtain a graft with a laparoscopic technique. The mean operating time was 152 minutes, the average bleeding was 12 cc, and the average hospital stay was 2.8 days. The complication rate was 7.6% (four patients with Clavien-Dindo I complication and two Clavien-Dindo IIIb patients). There were no cases of mortality. Conclusions. The laparoscopic technique is safe, with a low morbidity rate and excellent benefits.

RESUMO

OBJECTIVE: To present the results of our case series on laparoscopic nephrectomy in xanthogranulomatous pyelonephritis (XGP). METHODS: A retrospective study was conducted that included 143 patients treated with laparoscopic nephrectomy for non-functioning kidney, of whom 15 had XGP, within the time frame of 2011 to 2019. The demographic and clinical data were collected, along with the intraoperative results, complications, and days of hospital stay. RESULTS: Transperitoneal laparoscopic nephrectomy was successfully performed on 15 patients with XGP, with no need for conversion. Mean intraoperative time was 124.4 minutes (range 70-240) and intraoperative blood loss was 148.5 ml (range 30-550), with no blood transfusion required. No intraoperative complications occurred but there was one postoperative complication (6.6%), classified as Clavien-Dindo I (surgical wound infection). Mean hospital stay was 2.85 days (range 2-7). CONCLUSIONS: Nephrectomy is the definitive management for XGP, and the laparoscopic approach should be considered a treatment modality, despite the fact that the pathology involves a severe chronic inflammatory process. Its benefits are reduced surgery duration, less blood loss, a lower complication rate, and fewer days of hospital stay, when performed by a skilled and experienced surgeon.


OBJETIVO: Presentar los resultados de nuestra serie de nefrectomía laparoscópica en pielonefritis xantogranulomatosa (PXG). MÉTODO: Se realizó un estudio retrospectivo que incluyó 143 pacientes tratados con nefrectomía laparoscópica por exclusión renal, de los cuales 15 fueron por PXG, en el periodo comprendido de 2011 a 2019. Se recolectaron datos demográficos y clínicos, resultados transoperatorios, complicaciones y días de estancia hospitalaria. RESULTADOS: Se realizó nefrectomía laparoscópica transperitoneal de forma exitosa en 15 pacientes con PXG, sin necesidad de conversión. El tiempo transoperatorio promedio fue de 124.4 minutos (rango: 70-240). El sangrado transoperatorio fue de 148.5 ml (rango: 30-550), sin requerimiento de transfusión sanguínea. No se reportaron complicaciones transoperatorias; se presentó una complicación en el posoperatorio (6.6%) clasificada como Clavien-Dindo I (infección de la herida quirúrgica). La estancia hospitalaria promedio fue de 2.85 días (rango: 2-7). CONCLUSIONES: El manejo definitivo de la PXG es la nefrectomía, y el abordaje laparoscópico debe ser considerado como una modalidad de tratamiento a pesar de ser una patología que presenta un proceso inflamatorio grave y crónico, obteniéndose beneficios como disminución en el tiempo quirúrgico, menor sangrado, menor tasa de complicaciones y menos días de estancia hospitalaria cuando es realizado por un cirujano experimentado.

RESUMO

Antecedentes: La primera nefrectomía laparoscópica en pediatría fue realizada por el Dr. Martin Koyle en un niño de 8 meses con displasia renal multiquística. En la actualidad este procedimiento es aceptado como estándar de oro para realizar cualquier nefrectomía en patología renal benigna en adultos o niños, ya que permite una mejor exposición anatómica y mejor control vascular con una estancia más corta, menor uso de analgésicos y mejor resultado estético. Descripción de los casos clínicos: se presenta una serie de casos de nefrectomía laparoscópica comprendidas desde agosto 2001 a agosto de 2019 realizadas en el Hospital de Especialidades del Instituto Hondureño del Seguro Social localizado en el Barrio La Granja de Tegucigalpa, incluyendo en forma consecutiva todos los pacientes que ameritaron una nefrectomía programada en riñón no funcional por patología renal benigna. Durante ese período se diagnosticaron 12 displasias renales, 9 hidronefrosis obstructivas, 2 nefropatías por reflujo y 2 riñones ectópicos, de los cuales 23 fueron diagnósticos prenatales y 2 posnatales, una infección urinaria y una hipertensión. Se realizó un total de 25 nefrectomías laparoscópicas de forma segura y exitosa sin ninguna conversión a cirugía abierta ni morbilidades. Todos los pacientes iniciaron la vía oral a las 6 horas postoperatorias y fueron dados de alta antes de completar las 24 horas intrahospitalarias. Conclusiones: La nefrectomía laparoscópica es un procedimiento seguro y exitoso en pediatría, aun cuando el tiempo operatorio es más prolongado, permite en forma más temprana el inicio de la vía oral alta precoz con resultados estéticos superiores...(AU)

RESUMO

Objetivos Nuestro objetivo es demostrar que la incisión de Pfannenstiel presenta un perfil más seguro en cuanto a complicaciones postoperatorias frente a otro tipo de incisiones que habitualmente se utilizan para la extracción renal laparoscópica. Material y métodos Estudio retrospectivo y comparativo de 256 pacientes intervenidos de nefrectomía o nefroureterectomía. Dividimos a los pacientes en dos grupos: extracción renal mediante incisión de Pfannenstiel (grupo 1) y extracción renal mediante otro tipo de incisiones (grupo 2). Evaluamos: aparición de eventración y evisceración clínica y subclínica, presencia de infección bacteriana significativa, presencia de dolor, aparición de seroma, hematoma/sangrado, dehiscencia de la herida y parálisis muscular en cada paciente. Resultados Los pacientes del grupo Pfannenstiel presentaron una tasa de complicaciones derivadas de la herida de 11,72% frente a 27,34% en el grupo no-Pfannenstiel, p = 0,002, siendo significativo la menor tasa de dehiscencia (5,5 vs. 12,5%, p = 0,047) y seroma (3,1% vs. 7,8%, p = 0,022). El modelo de regresión logística multivariante mostró que la incisión de Pfannenstiel es un predictor de prevención de complicaciones derivadas de la herida quirúrgica (OR = 0,34, p = 0,005). Conclusiones La elección de una incisión de Pfannenstiel supuso una menor incidencia de dehiscencia y seroma de la herida quirúrgica, permitiendo la extracción de piezas de nefrectomía más voluminosas y con una menor estancia hospitalaria, lo que la convierte en una alternativa válida y segura, con un favorable perfil de complicaciones con respecto a otro tipo de incisiones (AU)


Objectives The aim of our study is to demonstrate that the Pfannenstiel incision is a reliable option in terms of postoperative complications compared to other types of incisions usually performed for kidney extraction after laparoscopic nephrectomy. Materials and methods Retrospective and comparative study of 256 patients who underwent laparoscopic nephrectomy or nephroureterectomy. Patients were divided into two groups: specimen extraction by Pfannenstiel incision (group 1) and specimen extraction by way of other incisions (group 2). Incisional hernia, surgical site infection, pain score, seroma, haematoma/bleeding, wound dehiscence and muscle paralysis were analyzed in each patient. Results Patients in Pfannenstiel group presented a rate of wound complications of 11.72% vs 27.34% with other incisions, p = 0.002, it was significantly inferior the rate of wound dehiscence (5.5% vs 12.5%, p = 0.047) and seroma (3.1% vs 7.8%, p = 0.022). Using multivariate logistic regression, Pfannenstiel incision was a significant protective predictor factor for wound complications (OR = 0.34, p = 0.005). Conclusions The Pfannenstiel incision allowed the extraction of bigger kidney masses with less incidence of dehiscence, seroma and in general wound complications. The hospital stay was lower in Pfannenstiel extraction group. These results present this incision as a reliable and safe option in the decision of which incision to select (AU)

RESUMO

Congenital diaphragmatic hernia incidence is one in 3000 live births, Bochdalek hernia occurs through a posterolateral defect. It is very rare in adults. We present a case of late relapsed one diagnosed in an adult male. He underwent an open intervention of Bochdalek hernia at first day of life and required reintervention at seventh month due to recurrence. Now, computerized tomography scan demonstrates a right diaphragmatic defect with intrathoracic hydronephrotic kidney. Nephrectomy was performed with Video-assisted Thoracic Surgery using laparoscopic ports and material. The diaphragmatic defect was closed with a polypropylene mesh. The patient was discharged after 72 h. (AU)

RESUMO

BACKGROUND: Currently there are no studies that determine the safety and quality of life of kidney donors in Mexico. OBJECTIVE: To determine the safety of being a kidney donor and the quality of life, comparing the open approach with hand-assisted laparoscopic technique. METHOD: Observational, cross-sectional, analytical study of the kidney donors in our hospital from January 2015 to December 2018, in two groups: open technique and hand-assisted laparoscopic. To determine safety, the Clavien-Dindo scale and transoperative bleeding were used, and the SF-36 health-related quality of life questionnaire was applied. RESULTS: There are no reports of peri-operative complications in any type of approach. All the patients obtained a grade I in the Clavien-Dindo scale. When the difference in the score of the SF-36 health-related quality of life questionnaire in kidney donor patients with hand-assisted laparoscopic surgical approach versus open approach was compared, a difference between both means of 14.05 was obtained, with p < 0.0001 in favor of the hand-assisted approach. CONCLUSIONS: Being a kidney donor is safe and the approach that we recommend is hand-assisted laparoscopic nephrectomy.


ANTECEDENTES: Actualmente en México no hay estudios que determinen la seguridad y la calidad de vida de los donadores renales. OBJETIVO: Determinar la seguridad de ser donador renal y la calidad de vida, comparando el abordaje abierto frente al laparoscópico mano-asistido. MÉTODO: Estudio observacional, transversal, analítico, de todos los donadores renales de nuestro hospital de enero de 2015 a diciembre de 2018, con seguimiento mínimo de 2 años. Se dividieron en dos grupos: operados con técnica abierta o laparoscópica mano-asistida. Para determinar la seguridad se utilizaron la escala de Clavien-Dindo y el sangrado transquirúrgico, y se les aplicó el cuestionario SF-36 de calidad de vida relacionada con la salud. RESULTADOS: No se reportan complicaciones transquirúrgicas en ningún tipo de abordaje. Todos los pacientes obtuvieron grado I en escala de Clavien-Dindo. En el puntaje del cuestionario SF-36 en pacientes donadores renales con abordaje quirúrgico laparoscópico mano-asistido versus abordaje abierto se obtuvo una diferencia entre ambas medias de 14.05, con p < 0.0001 a favor del abordaje mano-asistido. CONCLUSIONES: Ser donador renal es seguro y el abordaje que recomendamos ofrecer es el laparoscópico mano-asistido.

RESUMO

A incidência dos casos de neoplasia de rim tem aumentado consideravelmente e o emprego da cirurgia minimamente invasiva poupadora de néfrons é, atualmente, considerado o padrão ouro para tumores T1a e T1b. Essa cirurgia pode ser realizada de forma minimamente invasiva, por meio da técnica laparoscópica e laparoscópica assistida por robô. No entanto, faz-se necessário um estudo para avaliar os resultados dessas duas técnicas, tendo em vista uma crescente difusão da técnica robô assistida e um maior número de cirurgiões em treinamento. Soma-se a isso a importância de preservação renal e de segurança oncológica, possibilitada pela nefrectomia parcial, que ainda é subutilizada devido à maior dificuldade técnica de realizá-la pela via laparoscópica. OBJETIVO: comparar a cirurgia aparoscópica com a cirurgia laparoscópica assistida por robô na realização da nefrectomia parcial, no período per e pós-operatório, quanto aos resultados de cada uma delas. MÉTODO: trata-se de uma coorte retrospectiva de 209 pacientes com neoplasia de rim localizado, submetidos à nefrectomia parcial laparoscópica no Hospital Madre Teresa, no período de outubro de 2014 a junho de 2019, e à nefrectomia parcial assistida por robô, no Hospital Felício Rocho, entre os anos de 2018 a 2021. Os dados do estudo foram coletados e gerenciados, usando-se as ferramentas eletrônicas de captura de dados REDCap, além da pesquisa de prontuário. A análise dos dados foi realizada utilizandose o software SPSS versão 25. Em todos os testes estatísticos, foi considerado um nível de significância de 5%. RESULTADOS: em relação a fatores clínicos e cirúrgicos, observou-se que o tempo cirúrgico em horas, a permanência no hospital e a permanência no CTI foram maiores no grupo de nefrectomia parcial laparoscópica, quando comparados à nefrectomia parcial laparoscópica assistida por robô. Variáveis como complicações operatórias, hemotransfusão no per operatório, tipo de tumor, tamanho da lesão na peça cirúrgica e margens acometidas não mostraram diferença significativa entre os grupos (p>0,05). As complicações pós-operatórias foram mais frequentes no grupo de nefrectomia parcial laparoscópica (16,7%) quando comparadas ao grupo nefrectomia parcial laparoscópica assistida por robô (7,0%). O estadiamento pós-operatório também apresentou diferença significativa entre os grupos, sendo que os estádios iniciais (T0 e T1) foram proporcionalmente maiores no grupo de nefrectomia parcial laparoscópica, quando comparados ao grupo nefrectomia parcial laparoscópica assistida por robô. Já os estádios (T2 e T3) foram mais incidentes no grupo de nefrectomia parcial laparoscópica assistida por robô em relação ao outro grupo. CONCLUSÃO: com base nos resultados, pode-se afirmar que a técnica robô-assistida apresenta ganhos técnicos significativos e possibilita a ressecção de tumores tecnicamente mais difíceis, com menor taxa de complicações no pós-operatório. Apresenta tempo cirúrgico e tempo de internação hospitalar reduzidos em comparação com a cirurgia realizada por laparoscopia, além de alta precoce para aqueles que necessitam de unidade de terapia intensiva no pósoperatório.


Kidney cancer cases have increased considerably, and minimally invasive nephronsparing surgery is currently considered the gold standard for T1a and T1b tumors. This surgery can be performed minimally invasively, using the laparoscopic and robotassisted laparoscopic techniques. However, a study to evaluate the results of these two techniques is necessary, considering the increasing diffusion of the robot-assisted technique and the larger number of surgeons in training. Added to this is the importance of renal preservation and oncologic safety, made possible by partial nephrectomy, which is still underutilized due to the incredible technical difficulty of performing it laparoscopically. OBJECTIVE: To compare laparoscopic surgery with robot-assisted laparoscopic surgery in performing partial nephrectomy, in the per- and postoperative periods, regarding the results of each. METHODS: This is a retrospective cohort of 209 patients with localized kidney cancer who underwent laparoscopic partial nephrectomy at Hospital Madre Teresa from October 2014 to June 2019 and robot-assisted partial nephrectomy at Hospital Felício Rocho between the years 2018 and 2021. Study data were collected and managed using REDCap electronic data capture tools and chart search. Data analysis was performed using SPSS version 25 software. A 5% significance level was considered in all statistical tests. RESULTS: Regarding clinical and surgical factors, surgical time in hours, hospital stay, and intensive care unit stay were higher in the laparoscopic partial nephrectomy group when compared to the robot-assisted laparoscopic partial nephrectomy. Variables such as operative complications, intraoperative blood transfusion, tumor type, size of the lesion on the surgical specimen, and affected margins showed no significant difference between groups (p>0.05). The variable postoperative complications showed higher frequency in the laparoscopic partial nephrectomy group (16.7%) compared to the robot-assisted partial nephrectomy group (7.0%). Postoperative staging also showed significant differences between groups, with early stages (T0 and T1) proportionally higher in the laparoscopic partial nephrectomy group when compared to the robot-assisted laparoscopic partial nephrectomy group. Stages (T2 and T3) were higher in the laparoscopic robot-assisted partial nephrectomy group compared to the other group. CONCLUSION: Based on the results, it can be stated that the robot-assisted technique presents significant technical gains and allowed the resection of tumors that are technically more difficult and with a lower rate of complications in the postoperative period. It presented reduced surgical time and hospital stay compared to the surgery performed by laparoscopy. In patients who need to be referred to the intensive care unit postoperatively, the robot-assisted technique demonstrates a reduction in the length of stay in the intensive care unit.

RESUMO

La nefrectomia parcial ha proporcionado múltiples beneficios principalmente en pacientes con lesiones renales de pequeño tamaño o con enfermedades que puedan afectar el funcionamiento renal a largo plazo, también en pacientes con riñón único funcional, ya sea congènita o por cirugía, enfermedad renal terminal, tumores renales bilaterales o con enfermedades cromosómicas que afecten la función renal.Se presenta el caso de un paciente de 52 años con un tumor de riñón derecho de 10 cm de diámetro en región interpolar, con riñón izquierdo sin función, por proceso obstructivo de estenosis ureteropielica congènita. Se realizó nefrectomia parcial derecha a pesar de la localización y tamaño del tumor renal, obteniendo excelentes resultados oncológicos y funcionales. Con un seguimiento a doce meses de evaluación post-operatoria sin datos de actividad tumoral, presentando una función renal con creatinina 1.6 mg/dl, con evolución satisfactoria. Conclusiones: La nefrectomia parcial es el manejo ideal para tumores renales pequeños que están localizados en la corteza renal y en los extremos polares del riñón o con un riñón contralateral sin función; pero hay el dilema cuando se presentan en pacientes con función renal baja o tumores localizados cerca del hilio renal de más de 5 cm de diámetro, se debe tomar los riesgo de intentar realizar este procedimiento, el abordaje por via laparoscópica es excelente opción con excelentes resultados, con menor riesgo de complicaciones, y menor sangrado que cirugía abierta.


Nephron-sparing surgery (partial nephrectomy) has provided multiple benefits, mainly in patients with small kidney lesions or concomitant diseases that affect overall kidney function in long term, also in patients with a single functional kidney, either congenital or by surgery, end-stage renal disease, bilateral renal tumors or with chromosomal diseases that affects the renal function. The case of a 52-years-old male patient is presented with a 10-cm right kidney tumor in the interpolar region, with not functional left kidney exclusion due to an obstructive process by congenital ureteropyelic stenosis. Right nephron-sparing nephrectomy was performed despite the location and size of the tumor, obtaining excellent oncological and functional results. Follow-up at twelve months of postoperative evolution showed no data of tumor activity, presenting renal function with creatinine of 1.6 mg/dl, with satisfactory evolution. Conclusions: Partial nephrectomy is the standard management for small-volume renal tumors located in the renal cortex and polar areas, or not functional contralateral kidney; but there is the dilemma, when patients appear with impaired renal function or tumors located near the renal hilum by > 5 cm of diameter, the risk of performs this procedure must be taken, the laparoscopic approach is an excellent option. with great results, and minor bleeding than open surgery.

RESUMO

Objetivo: La nefrectomía parcial laparoscópica off-clamp tras la embolización arterial superselectiva (NPLh) en un quirófano híbrido es un abordaje mínimamente invasivo prometedor. En este estudio comparamos los resultados quirúrgicos perioperatorios de esta técnica innovadora con los de la técnica estándar de nefrectomía parcial laparoscópica convencional (NPLc).Pacientes y métodos: En total se incluyeron 86 y 127 pacientes tratados con NPLh y NPLc, respectivamente. Las dos técnicas se compararon en términos de complicaciones quirúrgicas, pérdida de sangre estimada (PSE), tiempo quirúrgico, duración de la estancia hospitalaria (DEH), márgenes quirúrgicos y tasa de consecución de la Trifecta (definida como duración de isquemia caliente <25min, márgenes quirúrgicos negativos y ausencia de complicaciones). Se utilizó una puntuación de propensión basada en la edad, el sexo, el índice de masa corporal (IMC), la tasa de filtración glomerular estimada (TFGe) preoperatoria y el tamaño tumoral para un emparejamiento 1:1 de los pacientes de cada grupo. Tras el emparejamiento, se obtuvieron dos grupos de 67 pacientes con características similares.Resultados: La tasa de conversión a cirugía abierta, las complicaciones y la PSE fueron similares entre ambos grupos. Por el contrario, el tiempo quirúrgico, la DEH y las tasas de Trifecta favorecieron la NPLh. El análisis multivariante demostró que la NPLh tenía un 70% más de probabilidades de lograr la Trifecta que la NPLc en todos los grupos de edad y para cualquier tamaño tumoral en toda la población del estudio.Conclusión: En comparación con el abordaje convencional, la nefrectomía parcial laparoscópica sin clampado después de la embolización arterial superselectiva en una sala híbrida mostró resultados quirúrgicos satisfactorios inmediatos y alcanzó una mayor tasa de consecución de la Trifecta. Se necesitan resultados funcionales y oncológicos a medio y a largo plazo para establecer esta


Objective: Off-clamp laparoscopic partial nephrectomy in a hybrid operating room after superselective arterial embolization (hLPN) is a promising minimally invasive approach. In this study, we compared the perioperative surgical outcomes of this innovative technique with the conventional standard of care laparoscopic partial nephrectomy (cLPN) technique.Patients and methods: Overall, 86 and 127 patients treated with hLPN and cLPN, respectively, were included. These two techniques were compared in terms of surgical complications, estimated blood loss (EBL), operative time, length of stay (LOS), surgical margins, and Trifecta achievement rate (defined as warm ischemia duration <25min, negative surgical margins and absence of complications). A propensity score based on age, gender, BMI, preoperative eGFR and tumor size was used for a 1:1 matching of patients of each group. After matching, two groups of 67 patients with similar characteristics were obtained.Results: Conversion rate to open surgery, complications and EBL were similar in both groups. Conversely, operative time, LOS and Trifecta rates favored hLPN. The multivariate analysis showed that hLPN had a 70% higher chance of Trifecta achievement than cLPN in all age groups and for all tumor size across the study population.Conclusion: Compared to a conventional approach, off-clamp laparoscopic partial nephrectomy in a hybrid room after superselective arterial embolization showed satisfying immediate surgical outcomes and reached a higher rate of Trifecta achievement. Mid and long-term functional and oncological results are needed to establish this minimally invasive surgical alternative (AU)

RESUMO

Introducción: El tumor neuroectodérmico primitivo periférico de riñón (PNETk) es una enfermedad rara muy agresivo que afecta mayormente a varones jóvenes. Reporte de caso: paciente varón de 19 años con cuadro clínico dolor abdominal, hematuria y masa palpable, en la tomografía se evidencia una enorme tumoración renal izquierda, Se le realiza nefrectomía radical convencional y se envía a estudio patológico más histoquímica resultando de PNETk. Luego paciente siguió su manejo por oncología para quimiterapia inicialmente. Conclusión: El PNETk que describimos representa el primer caso reportado en nuestro país, constituye una entidad clínica única por su rareza siendo un reto hacer diagnóstico y su comportamiento y manejo se sigue basando a reportes de casos debido a su poca frecuencia.


Introduction: Peripheral primitive neuroectodermal tumor of the kidney (PNETk) is a very aggressive rare disease that mainly affects young men. Case report: A 19-year-old male patient with symptoms of abdominal pain, hematuria and a palpable mass, the tomography shows a large left renal tumor. Conventional radical nephrectomy was performed and sent for pathology study plus histochemistry, resulting in PNETk. The patient then continued his oncology management for chemotherapy initially. Conclusion: The PNETk that we describe represents the first case reported in our country, it constitutes a unique clinical entity due to its rarity, being a challenge to make a diagnosis and its behavior and management is still based on case reports due to its infrequency.

RESUMO

Objetivo: La carcinomatosis peritoneal asociada al carcinoma de células renales es una entidad infrecuente, normalmente asociada a grandes masas renales, siendo muy rara su presentación tras la cirugía de tumores renales localizados. Nuestro objetivo es revisar la literatura y analizar los factores implicados en el desarrollo de carcinomatosis peritoneal tras nefrectomía parcial laparoscópica en tumores localizados.Material y métodos: Presentamos nuestra experiencia con 2 casos de carcinomatosis peritoneal tras cirugía parcial laparoscópica. Realizamos revisión de la literatura y analizamos los factores asociados al desarrollo de carcinomatosis peritoneal tras cirugía parcial laparoscópica en carcinoma de células renales.Resultados: Entre 2005-2018 en nuestro servicio fueron sometidos a nefrectomía parcial laparoscópica 225 pacientes por neoplasia renal localizada. Dos pacientes desarrollaron carcinomatosis peritoneal en el seguimiento, uno al año y medio de la cirugía y un segundo caso a los 7 años. Pocos casos de carcinomatosis peritoneal tras cirugías de neoplasia renal han sido descritos en la literatura, estando más frecuentemente asociados a grandes masas renales, con múltiples metástasis al diagnóstico, siendo el pronóstico infausto. Entre los factores implicados en su desarrollo pueden estar la diseminación de células tumorales durante la cirugía, la extensión tumoral directa o la metástasis por vía hematógena.Conclusiones: La carcinomatosis peritoneal tras nefrectomía parcial laparoscópica constituye un evento muy raro, pero que debe ser tenido en cuenta y, dado que es el único factor en el que podemos influir, extremar al máximo las precauciones durante el acto quirúrgico, siguiendo los principios oncológicos.

Objective: Peritoneal carcinomatosis associated with renal cell carcinoma is an infrequent entity, usually associated with large renal masses, and with a very rare presentation after surgery of localized renal tumors. Our objective is to review the literature and analyze the factors involved in the development of peritoneal carcinomatosis after laparoscopic partial nephrectomy in localized tumors.Material and methods: We present our experience with two cases of peritoneal carcinomatosis after laparoscopic partial nephrectomy. We reviewed the literature and analyzed the factors associated with the development of peritoneal carcinomatosis after laparoscopic partial surgery in renal cell carcinoma.Results: Between 2005-2018, 225 patients underwent laparoscopic partial nephrectomy for localized renal neoplasia in our service. Two patients developed peritoneal carcinomatosis during follow-up, at 1.5 and 7 years after surgery. Few cases of postoperative peritoneal carcinomatosis for renal neoplasia have been described in the literature, being more frequently associated with large renal masses, with multiple metastases at diagnosis, with a poor prognosis. The dissemination of tumor cells during surgery, direct tumor extension or metastasis by hematogenous route, are among the factors involved in the development of this condition.Conclusions: Peritoneal carcinomatosis after laparoscopic partial nephrectomy constitutes a very rare event. However, it should be taken into consideration, and, since it is the only factor we can influence, we must maximize precautions during the surgical act, following oncological principles. (AU)

RESUMO

Abstract Introduction: Robot-assisted laparoscopic surgery is currently the surgical treatment of choice for small renal masses. Objective: Reviewing the anesthetic management and perioperative morbidity of patients undergoing robotic-assisted laparoscopic partial nephrectomy (RALPN) from 2009 to 2019 at Hospital Universitario Donostia. Methods: Retrospective, descriptive, observational study involving 343 patients. Results: 95 % of the patients were ASA II-III. Transient renal artery clamping was performed in 91 %, with a mean ischemia time of 17.79 minutes. The mean duration of the procedure under balanced general anesthesia was 184 min. Standard monitoring was performed along with invasive arterial pressure monitoring (IAP), central venous catheter (CVC) and EV1000 platform (Edwards®) for complex patients. Complications were recorded in 40 patients (11.67 %). Patients under anti-aggregation therapy experienced more bleeding than non-anti-aggregation patients (p 0.04) but did not require more transfusions. Patients with a higher anesthetic risk did not experience more complications. No statistically significant association was found between worsening renal function and the occurrence of intraoperative complications. 21 patients (6 %) were readmitted due to complications; the most frequent complication was renal artery pseudoaneurysm that required endovascular embolization. Conclusions: It should be highlighted that after ten years of experience with this technique, the patients with a higher anesthetic risk have not experienced serious perioperative complications. RALPN is a safe technique that demands a careful anesthetic support. A robot-assisted approach alone is not a guarantee for success without strong teamwork.


Resumen Introducción La cirugía laparoscópica asistida por robot es actualmente el tratamiento quirúrgico de elección para masas renales de pequeño tamaño. Objetivo Revisión del manejo anestésico y morbilidad perioperatoria de los pacientes sometidos a nefrectomía parcial laparoscópica asistida por robot (NPLAR) desde 2009 a 2019 en el Hospital Universitario Donostia Metodología Estudio retrospectivo observacional descriptivo sobre 343 pacientes. Resultados El 95 % de los pacientes eran ASA II-III. En el 91 % se realizó pinzamiento transitorio de la arteria renal, con un tiempo medio de isquemia de 17,79 minutos. La duración media de la intervención bajo anestesia general balanceada fue de 184 minutos. Se realizó monitorización estándar junto con monitorización de presión arterial invasiva (PAI), catéter venoso central (CVC) y plataforma EV1000 (Edwards®) para pacientes complejos. Se registraron complicaciones en 40 pacientes (11,67 %). En los pacientes en tratamiento con antiagregantes hubo mayor sangrado que en los no antiagregados (p = 0,04), pero no requirieron más transfusiones. Los pacientes con un mayor riesgo anestésico no sufrieron más complicaciones. No se encontró asociación estadísticamente significativa entre el empeoramiento de la función renal y la existencia de complicaciones intraoperatorias. El 6 %, es decir, 21 pacientes, reingresaron por complicaciones de las cuales, la más frecuente fue el pseudoaneurisma de la arteria renal que necesitó embolización endovascular. Conclusiones Tras diez años realizando esta técnica se puede destacar que, aunque los pacientes presentan un riesgo anestésico elevado no han tenido complicaciones perioperatorias graves. La NPLAR es una técnica segura que precisa un cuidadoso soporte anestésico. La tecnología robótica no garantiza por sí misma el éxito sin un buen trabajo en equipo.

RESUMO

Abstract We present a 9-year-old patient with end-stage renal disease, on peritoneal dialysis, who underwent a staged prone retroperitoneoscopic bilateral nephrectomy. Bilateral nephrectomy was indicated in preparation for renal transplant in the context of genetic predisposition malignancy when immunosuppressed. The two mirror-image surgeries enable the comparison of the anesthetic management and outcomes in a single patient. Features of interest to anesthesiologists include approach to a child with chronic kidney disease, different requirements for intraoperative antihypertensives; pain management strategies, including a comparison of erector spinae plane block with and without adjunct dexmedetomidine; anesthetic management of retroperitoneoscopic pediatric surgery and the first description of using a Foley bag attached to a peritoneal dialysis catheter to aid in diagnosis and repair of posterior peritoneal cavity entry.


Resumen Se presenta un paciente de 9 años de edad con enfermedad renal terminal, en diálisis peritoneal, quien se sometió a nefrectomía bilateral retroperitoneoscópica estadificada en posición prona. Se indicó la nefrectomía bilateral en preparación para trasplante renal en el contexto de predisposición genética hacia desarrollar una patología maligna al estar inmunosuprimido. Las dos cirugías en espejo permiten hacer una comparación del manejo anestésico y de los desenlaces en un mismo paciente. Las características de interés para los anestesiólogos incluyen el abordaje de un niño con enfermedad renal crónica, con requisitos diferentes de antihipertensivos intraoperatorios; estrategias para el manejo del dolor, incluyendo una comparación de bloqueo del plano del erector espinal con y sin dexmedetomidina adyuvante; manejo anestésico de cirugía pediátrica retroperitoneoscópica y la primera descripción del uso de una bolsa Foley conectada a un catéter de diálisis peritoneal para ayudar en el diagnóstico y la reparación de la entrada de la cavidad peritoneal posterior.

RESUMO

Introducción Cabe esperar que la frecuencia de la fístula urinaria en la práctica urológica aumente como consecuencia de la ampliación de las indicaciones de la nefrectomía parcial, dado que obtiene resultados oncológicos equivalentes a los de la nefrectomía radical, pero con un menor riesgo de progresión a enfermedad renal crónica, menor morbilidad cardiovascular y mortalidad global. Objetivos Revisar y comparar las diferentes técnicas actuales de tratamiento activo para la fístula urinaria después de la nefrectomía parcial. Métodos Se realizó una búsqueda bibliográfica sistemática en la base de datos MEDLINE en marzo de 2020, combinando los términos: «urine leak», «urine leakage», «urinary leak» y «urinary fistula», con: «partial nephrectomy», «nephron sparing surgery» y «renal sparing surgery». Esta revisión sistemática se realizó de acuerdo con las guías de la declaración Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Solo se eligieron los artículos relacionados con el tratamiento activo. Se seleccionaron los resúmenes en inglés y español de las 2 últimas décadas. No hubo restricciones respecto al diseño del estudio ni la duración del seguimiento. Resultados primarios: 1) Tasa de resolución de la fuga, 2) Periodo de tiempo hasta la resolución de la fuga y 3) Número de intervenciones requeridas para la resolución. Resultados Se encontraron varios estudios. No hubo ningún ensayo controlado aleatorizado. La fístula urinaria puede resolverse de muchas maneras con el tratamiento activo, con una alta tasa de éxito (97,5%), una media de 1,4 intervenciones por paciente y un tiempo medio hasta la resolución de la fístula de 11 días (mediana de 3 días). Conclusión Existe un alto riesgo de sesgo debido a la metodología de los estudios. Sin embargo, hay un amplio abanico de alternativas eficaces y diversos abordajes para resolver la fístula urinaria en un periodo de tiempo adecuado (AU)


Introduction Urinary fistula is expected to become more frequent in urological practice as a result of expanding indication of partial nephrectomy given it́s oncological results equivalent to those of radical nephrectomy but at a lower risk of progression to chronic kidney disease, lower cardiovascular morbidity, and overall mortality. Objectives Review and compare different techniques of contemporary active management for urinary fistula after partial nephrectomy. Methods A systematic literature search on the MEDLINE database was conducted in March 2020, combining the terms: «urine leak», «urine leakage», «urinary leak» and «urinary fistula», with: «partial nephrectomy», «nephron sparing surgery» and «renal sparing surgery». The review of the literature was performed accordingto the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Only articles related to active treatment were eligible. Abstracts in English and Spanish from the last two decades were screened. No restriction based on study design nor the length of follow-up. Primary outcomes: 1) Leak resolution rate 2) Time course of leak resolution and 3) Number of interventions needed for resolution. Results Multiple studies were found. There were no randomized controlled trials. Urinary fistula can be solved in many ways with active treatment, with a high success rate (97.5%), an average of 1.4 intervention-per-patients and a mean time for leak resolution of 11 days (median of 3 days). Conclusion There is a high risk of bias due to the study's methodology. There is a broad range of effective alternatives and various approaches to solve urinary fistula in an appropriate timing (AU)
