ABSTRACT
INTRODUCTION: In recent years, different urinary markers such as the Bladder Epicheck® have been developed in an attempt to reduce the number of cystoscopies in the follow-up of non-muscle invasive bladder cancer (NMIBC). AIM: To provide a systematic review of Bladder Epicheck® and its current clinical utility in the follow-up and detection of recurrence of NMIBC. MATERIAL AND METHODS: Systematic review based on a literature search of PubMed, Web of Science and Scopus databases until October 2023, according to PRISMA and Quadas-2 criteria. Sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of the marker were calculated. Diagnostic performance was evaluated by the area under the curve (AUC). RESULTS: Fifteen studies were analyzed (nâ¯=â¯3761) including 86.7% prospective studies. Of the patient series, 53.2% had received previous intravesical instillations. The mean Se of the biomarker in the detection of recurrence varied according to tumor grade (87.9%-high grade/HG vs. 44.9%-low grade/LG, respectively). Their weighted mean Se and Sp were 71.6% and 84.5%, respectively. The mean recurrence rate was 29.1%. The weighted mean PPV and NPV were 56.4% and 92.8% (97.7% non-LG), respectively. The mean AUC was 85.63%. CONCLUSION: Bladder Epicheck® is a useful urinary marker in the follow-up of NMIBC, with significantly high Se and NPV in the detection of recurrences, especially in cases of HG disease. Its use can reduce the number of cystoscopies required in the follow-up of NMIBC, improving the quality of life of patients and potentially increasing health economic savings.
ABSTRACT
PURPOSE OF REVIEW: Renal cell carcinoma presents a unique proclivity for vascular involvement giving rise to a peculiar form of locally advanced disease so-called tumor thrombus. To date, the only curative strategy for these cases remains surgery, which should aim to remove every vestige of macroscopic disease. Most of the preexisting literature advocates opening the vena cava to allow tumor thrombus removal and subsequent venous suture closure. However, inferior vena cava circumferential resection (cavectomy) without caval replacement is possible in the majority of cases since progressive occlusion facilitates the development of a collateral venous network aimed at maintaining cardiac preload. RECENT FINDINGS: Radical nephrectomy with tumor thrombectomy remains a surgical challenge not exempt of operative complications even in experienced hands. In opposition to what traditional cavotomy and thrombus withdrawal can offer, circumferential cavectomy without caval replacement would provide comparable or even better oncologic control, decrease the likelihood of operative bleeding, and prevent the development of perioperative pulmonary embolism. This review focuses on the rationale of circumferential IVC resection without caval replacement and the important technical aspects of this approach in cases of renal cell carcinoma with vascular involvement. We also include an initial report on the surgical outcomes of a contemporary series of patients managed under this approach at our center.

INTRODUCTION: Stress urinary incontinence (SUI) is frequently associated with pelvic organ prolapse (POP) and may occur after its surgical treatment. AIM: To determine the incidence, risk factors and management of SUI during and after POP surgery through a review of the available literature. MATERIALS AND METHOD: Narrative literature review on the incidence and management of SUI after POP surgery after search of relevant manuscripts indexed in PubMed, EMBASE and Scielo published in Spanish and English between 2013 and 2023. RESULTS: Occult SUI is defined as visible urine leakage when prolapse is reduced in patients without SUI symptoms. De novo SUI develops after prolapse surgery without having previously existed. In continent patients, the number needed to treat (NNT) to prevent one case of de novo SUI is estimated to be 9 patients and about 17 to avoid repeat incontinence surgery. In patients with occult UI, the NNT to avoid repeat incontinence surgery is around 7. Patients with POP and concomitant SUI are the group most likely to benefit from combined surgery with a more favorable NNT (NNT 2). CONCLUSION: Quality studies on combined surgery for treatment SUI and POP repair are lacking. Continent patients with prolapse should be warned of the risk of de novo SUI, although concomitant incontinence treatment is not currently recommended. Incontinence surgery should be considered on an individual basis in patients with prolapse and SUI.
ABSTRACT
INTRODUCTION AND OBJECTIVE: Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. However, patients with coexistent Peyronie's disease (PD) and refractory erectile dysfunction and/or severe deformities may show different results. The aim of our study was to assess and to compare the level of satisfaction, with an inflatable penile prosthesis (IPP), in men with/without coexistent PD. MATERIAL AND METHODS: A survey study based on a five-item satisfaction questionnaire was submitted to all those live patients implanted in the period 1992-2022 at our center (n=570) and their partners. Ninety-two percent of implants were inflatable devices. Surgeries were mainly performed by two surgeons. The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after IPP. RESULTS: Of the 570 eligible patients, 479 (84%) completed the survey (393 Non-PD: GROUP 1; 70 non-complex PD-Group 2; 16 complex PD). Eighty-six per cent of patients in Group 1 reported satisfactory sexual intercourse (very or moderately satisfied). Non-complex PD implanted patients (Group 2) reported a global 81% satisfactory sexual intercourse (very or moderately satisfied) (p>0.05). However, when we evaluated the PD subgroup of patients with severe PD who require incision/excision/grafting at the time of implant (Group 3: n=20), only 61% reported satisfactory sexual intercourse (p<0.01) with predominance of moderately satisfied patients over very satisfied: 78% vs. 22%). Additionally, 84% (Group 1), 80% (Group 2) and 54% (Group 3) of partners reported satisfactory intercourses, respectively (p<0.01). Overall, 84% of Group 1 implants and 79% of Group 2 reported that they would undergo the procedure again if the IPP failed (p>0.05; ns). Only 50% of Group 3 patients would do it again. With regard to cosmetic aspects, 48% of the Group 3 implant reported penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of total PP patients expressed difficulty in manipulating the device. CONCLUSION: The presence of PD alone may not impact PP patient and partner satisfaction, but patients with more severe baseline deformity who require incision/grafting may be less satisfied with outcomes including penile length and glans sensation.

Introducción El tumor vesical músculo-infiltrante (TVMI) tiene una supervivencia libre de recidiva (SLR) del 50% a los cinco años, la quimioterapia neoadyuvante (QTN) ha aumentado la misma un 8%, pero no está claro qué pacientes se pueden beneficiar en mayor grado de la misma. Objetivo Evaluar el valor pronóstico del estado inmunológico-nutricional en los pacientes con TVMI candidatos a cistectomía, y desarrollar un score que permita identificar precistectomía a los pacientes con peor pronóstico (pT3-4 y/o pN0-1). Material y método Se realizó un análisis retrospectivo de 284 pacientes con TVMI tratados con cistectomía radical. Se revisó la analítica preoperatoria y se calcularon índices inmunonutricionales. El método de Kaplan-Meier se utilizó para el cálculo de la SLR. Para el análisis multivariante se utilizó la regresión de Cox. Resultados Mediante análisis univariante se observó una relación estadísticamente significativa con el índice leucocito/linfocito (p = 0,0001), el índice neutrófilo/linfocito (p = 0,02) el índice pronóstico nutricional (p = 0,002), y el ratio plaqueta/linfocito (p = 0,002). En análisis multivariante, el ratio leucocito/linfocito (p = 0,002) y el IPN (p = 0,04) se comportaron como factores pronósticos independientes de disminución de SLR, y se elaboró con ello un score pronóstico que divide a los pacientes en tres grupos pronósticos. El 80% de los pacientes con tumores pT3-4 y/o pN0-1 se encontraban en los grupos de pronóstico medio-malo. Conclusión La incorporación en la práctica clínica de un score inmunonutricional precistectomía ayudaría a seleccionar a un grupo de pacientes con estadio patológico más desfavorable y peor SLR. Creemos que estos pacientes podrían beneficiarse en mayor medida de una QTN (AU)
Introduction Muscle-infiltrating bladder tumor (MIBT) has a recurrence-free survival (RFS) of 50% at 5 years. Although neoadjuvant chemotherapy (NCT) has increased it by 8%, which group of patients benefits the most from this treatment remains unclear. Objective Evaluate the prognostic value of immune-nutritional status in patients with MIBT who are candidates for cystectomy, and to develop a score that allows identifying patients with a worse prognosis (pT3-4 and/or pN0-1). Material and methods A retrospective analysis was carried out on 284 patients with MIBT treated with radical cystectomy. Preoperative laboratory tests were analyzed and immune-nutritional indices were calculated. The KaplanMeier method was used to calculate the PFS. Cox regression was used for multivariate analysis. Results Univariate analysis showed a statistically significant relationship with leukocyte/lymphocyte index (p = 0.0001), neutrophil/lymphocyte index (p = 0.02), prognostic nutritional index (p = 0.002), and platelet/lymphocyte ratio (p = 0.002). In multivariate analysis, the leukocyte/lymphocyte ratio (p = 0.002) and PNI (p = 0.04) behaved as independent prognostic factors of decreased RFS. Based on these, a prognostic score was developed to classify patients into 3 prognostic groups. Eighty percent of patients with pT3-4 and/or pN0-1 tumors were in the intermediatepoor prognostic groups. Conclusion The implementation of a precystectomy immune-nutritional score in clinical practice would help in the selection of a group of patients with a more unfavorable pathologic stage and worse PFS. We believe that these patients could benefit more from a NACT (AU)

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)

Introducción y objetivos: Análisis comparativo de complicaciones postoperatorias y supervivencia entre nefrectomía parcial (NP) y radical (NR) laparoscópica en cáncer de células renales (CCR) cT1.Material y método: Estudio retrospectivo de pacientes birrenos con tumor renal único cT1 tratados en nuestro centro entre los años 2005 y 2018 mediante NP o NR laparoscópica.Resultados: Cumplieron los criterios de inclusión para el estudio 372 pacientes. Fueron tratados mediante NR 156 (41,9%) y 216 (58,1%) mediante NP. En 10 (4,6%) NP y 6 (3,9%) NR hubo complicaciones Clavien Dindo III-V (p = 0,75). El índice de comorbilidad de Charlson (ICC) se identificó como variable predictora independiente de complicaciones (p = 0,02), no influyendo el tipo de cirugía en el análisis multivariante. La estimación de la supervivencia global (SG) fue de 81,2 y de 56,8% a los 5 y 10 años en el grupo de NR y de 90,2 y 75,7% en el grupo de NP, respectivamente (p = 0,0001). Se identificaron como factores predictores de mortalidad global la obesidad (HR 2,77, p = 0,01), el ICC ≥ 3 (HR 3,69, p = 0,001) y el FG<60 mL/min/1,73 m2 al alta (HR 1,87,p = 0,03). El tipo de nefrectomía no demostró influencia en la SG. La estimación de la supervivencia libre de recidiva (SLR) fue de 86,1% a los 5 y 10 años en el grupo de NR y de 93,5 y 83,6% en el grupo de NP respectivamente (p = 0,22).Conclusiones: La NP laparoscópica no es inferior a la NR en términos de seguridad oncológica y quirúrgica en el CCR cT1. El tipo de nefrectomía no influyó en la SG del paciente, sin embargo, sí se comportaron como factores predictores la obesidad, el índice Charlson ≥ 3 y el FG<60 mL/min/1,73 m2 al alta (AU)
Introduction and objectives: Comparative analysis of postoperative complications and survival between laparoscopic partial nephrectomy (PN) and radical nephrectomy (RN) in cT1 renal cell carcinoma (RCC).Material and method: Retrospective study of patients with two kidneys and single renal tumor cT1 treated in our center between 2005 and 2018 by laparoscopic PN or RN.Results: 372 patients met the inclusion criteria for the study. RN was performed in 156 (41.9%) patients and PN in 216 (58.1%). Clavien Dindo III-V complications were observed in 10 (4,6%) PN and 6 (3,9%) RN patients (p = 0.75). The comorbidity Charlson index (CCI) was identified as an independent predictor variable of complications (p = 0.02) and surgical approach did not affect multivariate analysis. Estimated overall survival (OS) was 81.2% and 56.8% at 5 and 10 years in the RN group and 90.2% and 75.7% in the PN group, respectively (p = 0.0001). Obesity (HR 2.77, p = 0.01), CCI ≥ 3 (HR 3.69, p = 0.001) and glomerular filtration rate (GFR) < 60 mL/min/1.73m2 at discharge (HR 1.87, p = 0.03) were identified as predictors of overall mortality. Nephrectomy approach showed no influence on OS. Estimated recurrence-free survival (RFS) was 86.1% at 5 and 10 years in the RN group and 93.5% and 83.6% in the PN group, respectively (p = 0.22).Conclusions: Laparoscopic PN is not inferior to RN in terms of oncologic and surgical safety in cT1 RCC. Nephrectomy approach did not influence patient OS, however, obesity, CCI ≥ 3 and GFR<60 mL/min/1.73m2 at discharge did behave as predictors (AU)

Introducción: Las complicaciones surgidas de la anastomosis vesicoureteral en el trasplante renal influyen de forma importante en el éxito del trasplante; siendo las más graves y frecuentes la fístula y la estenosis de la unión ureterovesical. Actualmente se recomienda la colocación de catéteres doble J en esta anastomosis para reducir estas complicaciones.Objetivo: El objetivo del estudio es evaluar si la colocación de un CDJ influye en las complicaciones de esta anastomosis.Material y métodosSe ha realizado un análisis retrospectivo de 697 pacientes tratados con trasplante renal de donante cadáver en nuestro centro desde 1999 hasta 2018; y se ha comparado los resultados en función del uso o no de catéter doble J y la técnica quirúrgica realizada en la anastomosis.Resultados: En el 51,7% de los pacientes no se colocó CDJ; frente a un 48,3% en los que sí se colocó. La técnica más utilizada fue Lich-Gregoir. Se produjo fístula ureterovesical en un 5% de casos, y estenosis ureterovesical en un 4,2%. El CDJ se comportó como factor protector de fístula ureterovesical, pero no influyó significativamente en el desarrollo de estenosis. La técnica de Taguchi multiplicó el riesgo de desarrollar tanto fístula como estenosis ureterovesical. La incidencia de estenosis y de fístula fue significativamente mayor al combinar la técnica de Taguchi con la ausencia de catéter.Conclusión: El CDJ actúa como factor protector para las complicaciones de la estenosis ureterovesical. Los resultados de nuestro estudio parecen ir en concordancia con la literatura actual. (AU)
Introduction: Complications arising from ureterovesical anastomosis in kidney transplantation have an important influence on the success of the procedure. The most serious and frequent complications are fistula and stenosis of the ureterovesical junction. The placement of double J stents in anastomosis is currently recommended to reduce these complications.Objective: The aim of the study is to evaluate whether the placement of a DJ stent affects complications of anastomosis.Material and methodsRetrospective analysis of 697 patients treated with cadaveric donor renal transplant in our center from 1999 to 2018 was performed. Results were compared according to double J stent placement and the surgical technique employed for anastomosis.Results: Transplantation was performed without DJ placement in 51.7% of the patients, compared to 48.3% who were treated with DJ stent placement. The most commonly used technique was Lich-Gregoir. Ureterovesical fistula occurred in 5% of cases, and ureterovesical stenosis in 4.2%. DJ stent behaved as a protective factor for ureterovesical fistula but did not significantly influence the development of stenosis. The Taguchi technique greatly increased the risk of developing both ureterovesical fistula and stenosis. The incidence of stenosis and fistula was significantly higher when the Taguchi technique was combined with no DJ stent placement.Conclusion: DJ stent placement acts as a protective factor for ureterovesical stenosis complications. The results of our study seem to agree with current literature. (AU)

Objetivos Describir nuestra experiencia inicial con un novedoso abordaje laparoscópico inguinal y pélvico de acceso único mínimamente invasivo para realizar la disección de los ganglios linfáticos (DGL) en el cáncer de pene: la técnica de acceso único pélvico e inguinal (PISA, por las siglas en inglés de Pelvic and Inguinal Single Access).Material y métodos 10 pacientes en diversos estadios de carcinoma de células escamosas de pene (cN0 y ≥ pT1G3 o cN1/cN2) fueron operados mediante la técnica PISA entre 2015-2018. Se realizaron secciones congeladas intraoperatorias de forma rutinaria y se llevó a cabo secuencialmente la DGL pélvica ipsilateral como procedimiento en un solo acto y utilizando las mismas incisiones quirúrgicas ante la detección de ≥ 2 ganglios inguinales(pN2) o extensión ganglionar extracapsular (pN3). Variables: complicaciones posquirúrgicas a 30 días, pérdida de sangre estimada (PSE), tasa de transfusión, tiempo quirúrgico, tiempo hasta la retirada del drenaje y duración de la estancia hospitalaria (DEH). Las medianas y los rangos de los valores de las variables seleccionadas se presentaron como estadísticas descriptivas.Resultados La DGL inguinal fue bilateral en todos los casos y la DGL pélvica fue necesaria en el 40%. El tiempo quirúrgico total fue de 120-170 minutos y la mediana de PSE fue de 66 (30-100) cc. En ningún caso se requirió transfusión sanguínea. No se observaron complicaciones intraoperatorias y la tasa de complicaciones postoperatorias fue del 40% (10% de complicaciones mayores: linfocele inguinal sintomático). La mediana de la estancia hospitalaria fue de 5,8 (3-10) días. La mediana de tiempo hasta la retirada del drenaje inguinal fue de 4,7 días. Número medio de ganglios linfáticos extirpados mediante DGL inguinal: 10,25(8-14). Experiencia retrospectiva de volumen limitado de un centro de referencia con un seguimiento corto.
Objectives To describe our initial experience with a new minimally invasive inguinal and pelvic single-access laparoscopic approach, for performing lymph node dissection (LND) in penile cancer: the Pelvic and Inguinal Single Access (PISA) technique.Material and Methods 10 patients with different penile squamous cell carcinoma stages (cN0 and ≥pT1G3 or cN1/cN2) were operated by means of the PISA technique, between 2015-2018. Intraoperative frozen section analysis was carried out routinely and if ≥2 inguinal nodes (pN2) or extracapsular nodal extension (pN3) are detected, ipsilateral pelvic LND was performed sequentially as a single-stage procedure and using the same surgical incisions. Variables: 30-day postoperative complicactions, estimated blood loss (EBL), transfusion rate, operative time, time to drainage removal, and length of hospital stay (LOS). Medians and ranges of values for selected variables were reported as descriptive statistics.ResultsInguinal LND was bilateral in all cases, and pelvic LND was required in 40%. Total operative time was 120-170minutes and median EBL was 66 (30-100) cc. No blood transfusion was required. No intraoperative complications were noted, and postoperative complications rate was 40% (10% major complications- symptomatic inguinal lymphocele). Median LOS was 5.8 (3-10) days. Median time to inguinal drain removal was 4.7 days. Mean number of lymph nodes removed by inguinal LND: 10.25(8-14). Limited volume retrospective experience from a referral center with short follow-up. Outcomes reported may not be reproducible by surgeons with less experience and skills.Conclusions PISA is a novel, minimally invasive single-site surgical approach to one stage bilateral inguinal/pelvic LNDs for penile cancer showing a low rate of major complications

Introducción y objetivos Analizar la evolución de la función renal tras nefrectomía parcial (NP) y radical (NR) laparoscópica e identificar factores predictores de deterioro de función renal.Material y método Estudio retrospectivo de pacientes birrenos con filtrado glomerular (FG) > 60 mL/min/1,73 m2 y tumor renal único cT1 tratados en nuestro centro entre los años 2005 y 2018.Resultados 372 pacientes cumplieron los criterios de inclusión para el estudio. 156 (41,9%) fueron tratados mediante NR y 216 (58,1%) mediante NP. Al alta hubo una diferencia de 26,75 mL/min/1,73 m2 de FG entre NR y NP. La edad > 60 años, las complicaciones postoperatorias (OR 2,97, p = 0,005) y NR (OR 10,03, p = 0,0001) fueron factores predictores de FG<60 mL/min/1,73 m2 al alta. Únicamente la NR (OR 7,69, p = 0,0001) se comportó como factor pronóstico independiente de FG<45 mL/min/1,73 m2 al alta. La mediana de seguimiento de la serie fue de 57 (IQR 28 - 100) meses. Al final del seguimiento, nueve (6%) pacientes tratados con NR desarrollaron enfermedad renal crónica (ERC) grave y tres (2%) insuficiencia renal terminal (IRT). Edad > 70 años, diabetes mellitus (DM) (HR 2,12, p = 0,001), hipertensión arterial (HTA) (HR 1,73, p = 0,01) y NR (HR 2,88, p = 0,0001) se comportaron como factores predictores independientes de FG<60 mL/min/1,73 m2. Para un FG<45 mL/min/1,73 m2 fueron edad > 70 años, DM (HR 1,99 IC 95% 1,04 a 3,83, p = 0,04) y NR (HR 5,88 IC 95% 2,57 a 13,45, p = 0,0001).Conclusiones La NR es un factor de riesgo a corto y largo plazo de ERC, aunque con baja probabilidad de ERC grave o IRT en pacientes con FG > 60 mL/min/1,73 m2 preoperatoria. La edad, DM e HTA contribuyen al empeoramiento de la función renal durante el seguimiento (AU)
Introduction and objectives To analyze the evolution of kidney function after laparoscopic partial nephrectomy (PN) and radical nephrectomy (RN) and to identify predictive factors for deterioration in kidney function.Material and method Retrospective study of patients with two kidneys, glomerular filtration rate (GFR) > 60 mL/min/1.73 m2, and single renal tumor cT1, treated in our center between 2005 and 2018.Results A total of 372 patients met the inclusion criteria for the study; 156 (41.9%) were treated by RN and 216 (58.1%) by PN. There was a difference of 26.75 mL/min/1.73 m2 in GFR between RN and PN at discharge. Age > 60 years, postoperative complications (OR 2.97, p = 0.005) and RN (OR 10.03, p = 0.0001) were predictors of GFR<60 mL/min/1.73 m2 at discharge. Only RN (OR 7.69, p = 0.0001) behaved as an independent prognostic factor for GFR<45 mL/min/1.73m2 at discharge. The median follow-up of the series was 57 (IQR 28-100) months. At the end of the follow-up period, nine (6%) patients treated with RN developed severe chronic kidney disease (CKD) and three (2%) developed end stage renal disease (ESRD). Age > 70 years, diabetes mellitus (DM) (HR 2.12, p = 0.001), arterial hypertension (AHT) (HR 1.73, p = 0.01) and RN (HR 2.88, p = 0.0001) behaved as independent predictors of GFR<60 mL/min/1.73 m2. The independent predictors for GFR< 45 mL/min/1.73m2 were age >70 years, DM (HR 1.99 CI 95% 1.04-3.83, p = 0.04) and RN (HR 5.88 CI 95% 2.57-13.45, p = 0.0001).Conclusions RN is a short- and long-term risk factor for CKD, although with a low probability of severe CKD or ESRD in patients with preoperative GFR > 60 mL/min/1.73 m2. Age, DM and AHT contribute to worsening renal function during follow-up (AU)

Introducción y objetivos: La embolización prequirúrgica de la arteria renal (EPAR) puede emplearse en grandes masas renales antes de la nefrectomía para simplificar el procedimiento y disminuir el sangrado intraoperatorio. Nuestro objetivo es determinar el papel de la EPAR sobre el sangrado intraoperatorio y las complicaciones postoperatorias en los tumores renales izquierdos con trombo tumoral limitado a la vena renal izquierda (nivel-0).Material y métodosAnálisis retrospectivo de 46 pacientes intervenidos de nefrectomía radical izquierda y trombectomía como tratamiento de un carcinoma de células renales asociado a trombo tumoral de nivel 0 durante el periodo 1990-2020. La EPAR se limitó a aquellos casos en los que el acceso quirúrgico a la arteria renal principal se encontraba a priori dificultado en el estudio de imagen prequirúrgico (n=9; 19,6%). El sangrado intraoperatorio se estimó en base a la tasa de transfusión perioperatoria, y las complicaciones postoperatorias se categorizaron según la clasificación de Clavien-Dindo. Para el contraste de variables se utilizó el test Chi-cuadrado. Se realizó un análisis multivariable para identificar los predictores de transfusión y complicaciones.ResultadosNo existieron diferencias significativas en la tasa de complicaciones global (11,1 vs. 32,4%; p=0,19), complicaciones graves (0 vs. 8,1%; p=0,51), o tasa de transfusión (11,1 vs. 19%; p=0,49) entre ambos grupos (EPAR vs. no-EPAR). En el análisis multivariable la EPAR no se comportó como un predictor de complicaciones (OR: 0,11; IC95% 0,01-2,86; p=0,18) ni de transfusión (OR: 0.46; IC95% 0,02-7,38; p=0,58). (AU)
Introduction and objectives: Preoperative renal artery embolization (PRAE) for large renal masses may be performed prior to nephrectomy in order to simplify the procedure and reduce intraoperative bleeding. The objective of this work is to determine the role of PRAE on intraoperative bleeding and postoperative complications in left renal tumors with tumor thrombus limited to the left renal vein (level 0).Material and methodsRetrospective analysis to evaluate 46 patients who underwent left radical nephrectomy and thrombectomy for the treatment of renal cell carcinoma with level 0 tumor thrombus during the period 1990-2020. PRAE was limited to those cases in which surgical access to the main renal artery was presumed a priori difficult in the preoperative imaging study (n=9; 19.6%). Intraoperative bleeding was estimated based on the perioperative transfusion rate, and postoperative complications were categorized according to the Clavien-Dindo classification. The Chi-squared test was used for comparisons. A multivariate analysis was performed to identify predictors of transfusion and complications.ResultsThere were no significant differences in the overall complication rate (11.1% vs. 32.4%, P=.19), major complication rate (0% vs.8.1%, P=.51), or transfusion rate (11.1% vs. 19%, P=.49) between both groups (PRAE vs. non-PRAE). In the multivariate analysis, PRAE did not behave as a predictor of complications (OR:0.11, 95%CI 0.01-2.86; P=.18) nor transfusion (OR:0.46, 95%CI 0.02-7.38;P=.58). (AU)

Objetivo: Evaluar la seguridad y eficacia de la técnica de control de la vena cava inferior retrohepática por acceso anterior (RIVCA, por retrohepatic inferior vena cava control through an anterior approach) en el carcinoma de células renales (CCR) con trombo tumoral nivel iiia.Pacientes y métodosSerie inicial de 6 casos que presentan CCR con trombo tumoral nivel iiia intervenidos de nefrectomía radical y trombectomía tumoral mediante la técnica RIVCA entre 2018-2019. El objetivo de la técnica RIVCA es obtener un control completo de la vena cava inferior retrohepática por encima de la porción craneal del trombo tumoral, pero excluyendo las venas hepáticas mayores con el fin de preservar la circulación hepatocava natural. Se proporciona la descripción paso a paso del procedimiento. Se registraron prospectivamente los rasgos de la enfermedad, así como las características y los resultados quirúrgicos.ResultadosLa nefrectomía radical y la trombectomía tumoral se completaron en todos los casos. La técnica RIVCA no aumentó significativamente el tiempo quirúrgico (rango: 14-22min). La media de sangrado estimado fue de 325cc (rango: 250-400). No se requirió transfusión de sangre intraoperatoria en ningún caso. La media de unidades de concentrados de hematíes transfundidos por paciente en el período postoperatorio fue de 1,3 (rango: 0-2). No hubo casos de embolia pulmonar intraoperatoria ni se produjeron complicaciones mayores (Clavien-Dindo III-V) en el período postoperatorio a 30 días. La estancia hospitalaria postoperatoria (mediana) fue de 8 días (rango: 5-11). (AU)
Objective: To evaluate the safety and efficacy of the retrohepatic inferior vena cava control through an anterior approach (RIVCA) technique in renal cell carcinoma (RCC) with level iiia tumor thrombus.Patients and methodsInitial series of 6 cases presenting RCC and level iiia tumor thrombus who underwent radical nephrectomy and tumor thrombectomy using the RIVCA technique between 2018-2019. RIVCA technique aims to gain complete control of the retrohepatic inferior vena cava above the cranial end of the tumor thrombus, but excluding the major hepatic veins in order to preserve the natural hepato-caval shunt. A step-by-step description of the procedure is provided. Disease features, operative characteristics, and surgical outcomes were registered prospectively.ResultsRadical nephrectomy and tumor thrombectomy were completed in all cases. RIVCA technique did not increase operative time significantly (range: 14-22min). Mean estimated blood loss was 325cc (range: 250-400). Blood transfusion was not required intraoperatively in any of the cases. Mean postoperative transfusion rate was 1.3 red blood cells packed units (range: 0-2). There were no cases of intraoperative pulmonary embolism or major complications (Clavien-Dindo III-V) in the period of 30 days postoperatively. Median postoperative length of stay was 8 days (range: 5-11). (AU)

Antecedentes y objetivo La actualización de las series estándar de pruebas epicutáneas debe basarse en datos objetivos de frecuencia de sensibilización de los alérgenos que componen cada batería. La última renovación de la batería estándar española se realizó en 2016 y de la europea en 2019, quedando pendiente valorar la inclusión de alérgenos emergentes. Material y método Desarrollamos un estudio observacional, prospectivo y multicéntrico de los pacientes consecutivos del registro del Grupo Español de Investigación en Dermatitis y Alergia Cutánea sometidos a pruebas epicutáneas con hidroperóxido de linalool, hidroperóxido de limoneno, 2-hidroxi-etil-metacrilato, benzisotiazolinona, octilisotiazolinona, mezcla textil, metabisulfito sódico, propóleo, bronopol, mezcla de compuestas II, diazolidinil urea, imidazolidinil urea, decil glucósido y lauril glucósido, durante los años 2019 y 2020. Resultados Se analizó una muestra de 4.654 pacientes estudiados con diazolidinil urea, imidazolidinil urea y bronopol, y de 1.890 pacientes con el resto de los alérgenos. El índice MOAHLFA fue: M 30%, O 18%, A 15%, H 29%, L 6,5%, F 23%, A 68%. Siete alérgenos mostraron una frecuencia de sensibilización mayor del 1%: hidroperóxido de linalool, 2-hidroxi-etil-metacrilato, benzisotiazolinona, hidroperóxido de limoneno, mezcla textil, metabisulfito sódico y propóleo. Tres alérgenos mostraron una frecuencia de relevancia presente superior al 1%: hidroperóxido de linalool, 2-hidroxi-etil-metacrilato e hidroperóxido de limoneno; para benzisotiazolinona y mezcla textil, esta frecuencia fue de entre el 0,9 y el 1%. Conclusiones Nuestros resultados indican que debería valorarse la inclusión de siete nuevos alérgenos en la batería estándar española. Estos resultados podrían contribuir a la próxima actualización de la batería basal europea (AU)
Background Standard patch test series must be updated using objective data on allergen sensitization. The Spanish standard series was last updated in 2016 and the European series in 2019, and the inclusion of several emerging allergens needs to be evaluated. Material and methods We conducted a prospective, observational, multicenter study of consecutive patients from the registry of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) who were patch tested in 2019 and 2020 with linalool hydroperoxide, limonene hydroperoxide, 2-hydroxyethyl-methacrylate, benzisothiazolinone, octylisothiazolinone, textile dye mix (TDM), sodium metabisulfite, propolis, bronopol, Compositae mix II, diazolidinyl urea, imidazolidinyl urea, decyl glucoside, and lauryl glucoside. Results We analyzed data for 4654 patients tested with diazolidinyl urea, imidazolidinyl urea, and bronopol, and 1890 tested with the other allergens. The values for the MOAHLFA index components were 30% for male, 18% for occupational dermatitis, 15% for atopic dermatitis, 29% for hand, 6.5% for leg, 23% for face, and 68% for age > 40 years. Sensitization rates above 1% were observed for 7 allergens: linalool hydroperoxide, 2-hydroxyethyl-methacrylate, benzisothiazolinone, limonene hydroperoxide, TDM, sodium metabisulfite, and propolis. Three allergens had a current relevance rate of over 1%: linalool hydroperoxide, 2-hydroxyethyl-methacrylat, and limonene hydroperoxide. Benzisothiazolinone and TDM had a relevance rate of between 0.9% and 1%. Conclusions Our results indicate that 7 new allergens should be considered when extending the Spanish standard patch test series. The data from our series could be helpful for guiding the next extension of the European baseline series (AU)

Introducción: El riñón en herradura es una anomalía congénita poco frecuente en la población general que combina ectopia renal, malrotación y alteraciones en la vascularización. El tumor que más frecuentemente se desarrolla en estos casos es el carcinoma de células renales (50%).Una de sus características a destacar es la gran variabilidad en su anatomía, sobre todo a nivel vascular.Material y métodosPresentamos 2 casos de pacientes con diagnóstico de tumor renal en riñones en herradura, ambos tratados con nefrectomía parcial laparoscópica, llevados a cabo en nuestro servicio; y realizamos una revisión de la literatura actual.DiscusiónLas indicaciones de tratamiento quirúrgico en tumores en esta enfermedad son las mismas que en los riñones anatómicamente normales. Tradicionalmente, el tratamiento ha sido la cirugía abierta, siendo la heminefrectomía la cirugía de elección. En la actualidad se tiende a defender la cirugía conservadora de nefronas, y el abordaje laparoscópico ha adquirido más importancia progresivamente.ConclusiónEs fundamental realizar un estudio de imagen minucioso para una correcta planificación quirúrgica.

Introduction: The horseshoe kidney is a rare congenital anomaly in the general population that combines renal ectopia, malrotation and abnormal vascular supply. The most frequently developed tumor in this case is renal cell carcinoma (50%).One of its main characteristics is great anatomical variation, especially in terms of vascular structures.Material and methodsWe present two cases of patients with diagnosis of renal tumor in horseshoe kidneys, both treated with laparoscopic partial nephrectomy in our department. Additionally, we have carried a review of the current literature.DiscussionIndications for surgical treatment in this pathology are the same as in kidneys with normal anatomy. Traditionally, treatment has been open surgery, with heminephrectomy as surgery of choice. The current trend is to advocate nephron-sparing surgery, and the laparoscopic approach has been progressively gaining importance.ConclusionA thorough imaging study is essential for proper surgical planning.

Introducción: La infección de la arteria en el lugar de la anastomosis o a su alrededor es una complicación ominosa que se presenta comúnmente como una fuga y/o disolución local de la pared arterial.Material y métodosRevisión narrativa basada en artículos relevantes indexados en PubMed, EMBASE y Scielo, escritos en inglés o español, durante el período de enero del año 2000 a diciembre de 2019. Se realizó un análisis agrupado de acuerdo con la etiología. A partir de los resultados obtenidos con este enfoque, se sugiere un algoritmo diagnóstico/terapéutico para optimizar su manejo clínico.HallazgosLos pseudoaneurismas arteriales son hematomas contenidos pseudoencapsulados generados por una fuga arterial. Son infrecuentes (<1% de los casos), en su mayoría relacionados con una infección (contaminación del líquido de preservación o sepsis), y localizados en el sitio de anastomosis arterial en receptores de trasplante renal. Aunque con frecuencia se diagnostican en pacientes sintomáticos días/semanas después del trasplante, pueden pasar desapercibidos durante largos periodos de tiempo, siendo diagnosticados de forma incidental. La ecografía Doppler color confirma la sospecha clínica. La angioTC y la angiografía se utilizan para la planificación quirúrgica o el tratamiento endovascular, respectivamente. El diagnóstico etiológico se realiza en base al cultivo del tejido extirpado. La elección del enfoque del tratamiento se basa principalmente en la presentación clínica y la localización anatómica. Las opciones terapéuticas incluyen la inyección percutánea de trombina guiada por ecografía, el tratamiento endovascular y la cirugía. (AU)
Introduction: Infection of the artery at or around the anastomotic site is an ominous complication commonly presenting as a leak and/or local dissolution of the arterial wall.Material and methodsNarrative review based on relevant PubMed, EMBASE, and Scielo indexed English or Spanish-written articles for the period January 2000-December 2019. A pooled analysis regarding etiology was performed. Based on the results obtained with this approach, a diagnostic/therapeutic algorithm is suggested in order to optimize its clinical management.FindingsArterial pseudoaneurysms are pseudocapsuled contained hematomas generated as the result of an arterial leaking. They are infrequent(<1% of cases),mostly related with infection(contamination of preservation fluid or sepsis) and located at the arterial anastomotic site in renal transplantation recipients. Although they are frequently diagnosed in symptomatic patients days/weeks after transplantation, they may remain unnoticed for long periods being diagnosed incidentally. Color coded-Doppler ultrasound confirms the clinical suspicion. Angio CT-scan and angiography are used for surgical planning or endovascular treatment, respectively. The etiological diagnosis is made on a basis of excised tissue culture. The decision-making process regarding the treatment approach, mostly relies on clinical presentation and anatomical location. Therapeutic options include ultrasound-guided percutaneous thrombin injection, endovascular treatment, and surgery. (AU)

El diagnóstico y tratamiento del carcinoma de células renales asociado con trombosis venosa tumoral sigue suponiendo un reto en la actualidad, requiriendo de equipos multidisciplinares, fundamentalmente en niveles del trombo III y IV. Nuestro objetivo es la exposición de las distintas técnicas diagnósticas empleadas y de las controversias asociadas. Para ello se ha llevado a cabo una revisión de los artículos relacionados más relevantes entre enero del 2000 y agosto de 2020 en PubMed, EMBASE y Scielo. El continuo desarrollo tecnológico, ha permitido avanzar en su detección, en la aproximación del subtipo histológico y en la determinación del nivel del trombo tumoral. Independientemente de la técnica de imagen utilizada para su diagnóstico (TC, RMN, ETE, ecografía con contraste), es de vital importancia el tiempo transcurrido hasta su tratamiento con el fin de disminuir el riesgo de complicaciones, algunas de ellas fatales como la tromboembolia pulmonar.

Diagnosis and treatment of renal cell carcinoma with venous tumor thrombosis remains a challenge today, requiring multidisciplinary teams, mainly in tumor thrombus levels III-IV. Our objective is to present the various diagnostic techniques used and its controversies. A review of the most relevant related articles between January 2000 and August 2020 has been carried out in PubMed, EMBASE and Scielo. Continuous technological development has allowed progress in its detection, in the approximation of the histological subtype, and in the determination of tumor thrombus level. Regardless of the imaging technique used for its diagnosis (CT, MRI, TEE, ultrasound with contrast), the time elapsed until treatment is vitally important to reduce the risk of complications, some of them fatal, such as pulmonary thromboembolism.

INTRODUCCIÓN: Existe muy poca literatura española que compare resultados oncológicos tras prostatectomía radical (PR) según la vía de abordaje y la metodología es inadecuada. OBJETIVO: Comparar los resultados oncológicos en cuanto a márgenes quirúrgicos (MQ) y recidiva bioquímica (RB) entre PR abierta (PRA) y laparoscópica (PRL). MATERIAL Y MÉTODOS: Comparación de 2 cohortes (307 con PRA y 194 con PRL) entre 2007 y 2015. El estado de los MQ se clasificaron como positivos o negativos y la RB como la elevación del PSA después de la PR > 0,4 ng/ml. Para el contraste de variables cualitativas se utilizó el test Chi-cuadrado y ANOVA para las cuantitativas. Para evaluar los factores predictores de los MQ se ha realizado un análisis multivariante mediante regresión logística. Para evaluar los factores predictores de RB se ha realizado un análisis multivariable mediante regresión de Cox. RESULTADOS: El 43,5% de pacientes tuvieron un Gleason 7 (3 + 4) en la pieza quirúrgica y un 31,7% MQ positivos siendo el estadio patológico más frecuente pT2c en el 61,9%. No existieron diferencias significativas entre ambos grupos, excepto la afectación extracapsular (p = 0,001), más frecuente en la PRL. La mediana de seguimiento fue de 49 meses, evidenciando RB en el 23% de pacientes, sin diferencias significativas entre cohortes. En el análisis multivariable solo el grupo de riesgo D'Amico se comportó como factor predictor independiente de MQ positivos y el score de Gleason y los MQ positivos como factores predictores independientes de RB. CONCLUSIÓN: La vía de abordaje no influyó en el estado de MQ ni en la RB
INTRODUCTION: There are very few Spanish studies that compare oncological outcomes following radical prostatectomy (RP) based on surgical approach, and their methodology is not appropriate. OBJECTIVE: To compare oncological outcomes in terms of surgical margins (SM) and biochemical recurrence (BR) between open radical prostatectomy (ORP) and laparoscopic radical prostatectomy (LRP). MATERIAL AND METHODS: Comparison of two cohorts (307 with ORP and 194 with LRP) between 2007-2015. Surgical margin status was defined as positive or negative, and BR as a PSA rise of > 0.4 ng/ml after surgery. To compare the qualitative variables, we employed the Chi-squared test, and ANOVA was used for quantitative variables. We performed a multivariate analysis using logistic regression to evaluate the predictive factors of SM, and a multivariate analysis using Cox regression to evaluate the predictive factors of BR. RESULTS: Gleason 7 (3 + 4) was determined in the surgical specimens of 43.5% of patients, and 31.7% had positive SM. The most frequent pathological stage was pT2c, on the 61.9% of the cases. No significant differences were found between both groups, except for extracapsular extension (p = 0.001), more frequent in LRP. The median follow-up was 49 months. BR was seen in the 23% of patients, without significant differences between groups. In the multivariable analysis, only the D'Amico risk group behaved as an independent predictive factor of positive SM, and Gleason score and positive SM acted as independent predictive factors of BR. CONCLUSION: The surgical approach did not influence SM status or BR
