Estudio comparativo de la extracción de la pieza de nefrectomía laparoscópica mediante una incisión de tipo Pfannenstiel / Comparative study of intact specimen extraction in laparoscopic nephrectomy by pfannenstiel incision

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)

Síntomas de tramo urinario inferior y síndrome de apnea obstructiva del sueño: evolución urodinámica antes y después de un año de tratamiento con presión continua positiva de la vía aérea / Lower urinary tract symptoms and obstructive sleep apnea syndrome: Urodynamic evolution before and after one year of treatment with continuous positive airway pressure

Objetivo: Demostrar el potencial impacto urodinámico que puede tener el uso adecuado de presión continua positiva de la vía aérea (CPAP) en pacientes con síndrome de apnea-hipopnea obstructiva del sueño y observar si la posible mejoría de los síntomas de tramo urinario inferior es debida a alguna modificación urodinámica. Métodos: Estudio prospectivo con pacientes recientemente diagnosticados de síndrome de apnea-hipopnea obstructiva del sueño mediante poligrafía del sueño. Se estudian desde el punto de vista urológico para descartar importantes patologías urológicas. Se utilizan cuestionarios validados IPSS y OAB-V8, diarios miccionales de 3 días y estudios urodinámicos invasivos, todos ellos antes de comenzar con CPAP y tras un año de su uso adecuado. Resultados: Se llevan a cabo 84 estudios urodinámicos en 43 pacientes. La puntuación IPSS disminuye 3,58 puntos. La puntuación OAB-V8 disminuye 2,87 puntos. Los episodios de nicturia disminuyen más de uno por noche. El porcentaje de pacientes con poliuria nocturna disminuye un 26%. La acomodación vesical significativamente aumenta (97,39 vs. 200,40 ml/cm H2O). Disminuye la presencia de detrusor hiperactivo en el estudio urodinámico de 11 (antes de CPAP) a 5 pacientes (tras CPAP). Conclusión: Tras el tratamiento apropiado con CPAP se observa una mejoría estadística y clínica de distintos síntomas de tramo urinario inferior con escasa repercusión urodinámica

Objective: To report the clinical evolution and the urodynamic behaviour of several lower tract urinary symptoms in patients with obstructive sleep apnea syndrome before and after the treatment with continuous positive airway pressure (CPAP) devices. Methods: A prospective study was performed; patients with recent diagnosis of sleep apnea confirmed by nocturnal sleep polygraphy and absence of medical urological past history. In order to discard important lower urinary tract conditions, urological examinations were previously performed. Urinary symptoms were evaluated using the IPSS and OAB-V8 validated questionnaires, three-day Bladder Diary and invasive urodynamic examinations with a gap of one year before and one year after using the CPAP. Results: 84 urodynamic studies were carried out in 43 patients. The IPSS score decreased by 3.58 points. The OAB-V8 score decreased by 2.87 points. Nocturia episodes decreased to one per night. The percentage of patients with nocturnal polyuria went down to 26%. The bladder compliance significantly increased (97.39 vs 200.40ml/cm H2O). The presence of detrusor overactivity decreased from 11 (before CPAP) to 5 patients (after CPAP). Conclusion: The proper treatment with CPAP showed a statistical and clinical improvement of several LUTS with limited urodynamic modifications

Nefroureterectomía y desinserción transuretral láser-endoscópica en decúbito lateral sin cambio de posición: adaptación progresiva al abordaje por retroperitoneoscopia / Laparoscopic nephroureterectomy with laser endoscopic transuretral disinsertion in lateral decubitus: progressive adaptation to retroperitoneocopic approach

Introducción: La técnica de desinserción ureteral con rodete vesical continúa su evolución. Presentamos la técnica láser-endoscópica transuretral combinada con abordaje trans y retroperitoneal laparoscópicos en decúbito lateral, sin reposicionamiento del paciente para carcinomas uroteliales del tracto urinario superior. Materiales y métodos: Presentamos 3 nefroureterectomías laparoscópicas, una trans y 2 retroperitoneales. La desinserción se realizó en decúbito lateral utilizando un cistoscopio flexible y una fibra de 365 μ de laser Holmio. La técnica endoscópica se adaptó progresivamente a los abordajes retroperitoneoscópicos de 3 puertos y puerto único. Antes de la manipulación laparoscópica del riñón el uréter fue clipado por debajo del tumor, iniciándose posteriormente la técnica endoscópica. Ambos abordajes se combinaron simultáneamente. Resultados: Se lograron nefroureterectomías con desinserción endoscópica del rodete vesical en bloque, garantizando un sistema cerrado, comparable con la técnica abierta. El segundo caso precisó reconversión por problemas técnicos y prolongación del tiempo quirúrgico. No se diagnosticaron recidivas durante el seguimiento. Conclusión: Los resultados alcanzados son comparables con los de la cirugía abierta y la técnica garantizó el cumplimiento de los principios oncológicos. Permitió la desinserción en decúbito lateral evitando el reposicionamiento del paciente, ahorrando tiempo quirúrgico. Los resultados reflejaron los beneficios de la cirugía mínimamente invasiva en todos los casos

Background: The ureteral disinsertion with bladder cuff technique continues to evolve. We present the endoscopic laser transurethral technique combined with a transperitoneal and retroperitoneal laparoscopic approach in lateral decubitus, without patient repositioning, for treating urothelial carcinomas of the upper urinary tract. Materials and methods: We present 3 laparoscopic nephroureterectomies: 1 transperitoneal and 2 retroperitoneal. Disinsertion was performed in lateral decubitus using a flexible cystoscope and a 365-μm holmium laser fiber. The endoscopic technique was progressively adapted to 3-port and single-port retroperitoneoscopic approaches. Before laparoscopic handling of the kidney, ureter was clamped below the tumour. The endoscopic technique was then started. Both approaches were simultaneously employed. Results: Nephroureterectomies were achieved performing en bloc endoscopic disinsertion of the bladder cuff and ensuring a closed system comparable to open technique. The second case required reconversion due to technical problems and extension of the surgical time. No relapses were diagnosed during follow-up. Conclusion: Results are comparable to open surgery, technique ensured compliance to oncology principles, enabled disinsertion in lateral decubitus and avoid patient repositioning saving surgical time. The results reflect the benefits of minimally invasive surgery in all cases

Profilaxis antibiótica "dirigida" por cultivos rectales antes de la biopsia prostática transrectal: reducción de complicaciones infecciosas y costes de atención sanitaria / Rectal culture-directed antibiotic prophylaxis before transrectal prostate biopsy: Reduced infectious complications and healthcare costs

Introducción: La biopsia prostática transrectal ecográficamente dirigida (BPTE) se asocia a complicaciones infecciosas (CI). Las CI están relacionadas con un incremento de la prevalencia de bacterias ciprofloxacino-resistentes (BCR) en la flora rectal. Estudiamos las CI ocurridas en 2 grupos. Grupo de profilaxis antibiótica «dirigida» (GPD) vs. grupo de profilaxis empírica (GPE). Evaluamos el impacto económico que supone la profilaxis antibiótica «dirigida» (PD). Material y métodos: El GPD se estudió prospectivamente (junio 2013-julio 2014). Se recogieron cultivos rectales (CR) antes de BPTE y se sembraron en medios selectivos con ciprofloxacino para determinar la presencia de BCR. Los pacientes con bacterias sensibles recibieron ciprofloxacino. Pacientes con bacterias resistentes recibieron PD según antibiograma del CR. El GPE se estudió retrospectivamente (enero 2011-junio 2009). El CR no se realizó y todos los pacientes recibieron ciprofloxacino como profilaxis. Las CI ocurridas en ambos grupos se registraron en un periodo no superior a 30 días después de BPTE (historia clínica electrónica). Resultados: Trescientos pacientes fueron sometidos a BPTE, 145 recibieron PD y 155 PE. En el GPD, 23 pacientes (15,86%) presentaron BCR en CR. Solo un paciente (0,7%) experimentó ITU. En el GPE, 26 pacientes (16,8%) experimentaron múltiples CI (incluidas 2 sepsis) (p < 0,005). El coste total estimado, incluido el manejo de las CI, fue de 57.076 € con PE vs. 4.802,33 € con PD. El coste promedio/paciente con PE fue de 368,23 € vs. 33,11 € con PD. La PD logró un ahorro total estimado de 52.273,67 €. Es necesario que 6 pacientes se sometan a PD para prevenir una CI. Conclusiones: La PD se asoció a un notable descenso de la incidencia de CI causadas por BCR y redujo los costos de atención sanitaria

Transrectal ultrasound-guided prostate biopsy (TUPB) is associated with infectious complications (ICs), which are related to a greater prevalence of ciprofloxacin-resistant bacteria (CRB) in rectal flora. We examined the ICs that occurred in 2 groups: A guided antibiotic prophylaxis (GP) group and an empiric prophylaxis (EP) group. We assessed the financial impact of GP.: Material and methods: The GP group was studied prospectively (June 2013 to July 2014). We collected rectal cultures (RCs) before the TUPB, which were seeded on selective media with ciprofloxacin to determine the presence of CRB. The patients with sensitive bacteria were administered ciprofloxacin. Patients with resistant bacteria were administered GP according to the RC antibiogram. The EP group was studied retrospectively (January 2011 to June 2009). RCs were not performed, and all patients were treated with ciprofloxacin as prophylaxis. The ICs in both groups were recorded during a period no longer than 30 days following TUPB (electronic medical history). Results: Three hundred patients underwent TUPB, 145 underwent GP, and 155 underwent EP. In the GP group, 23 patients (15.86%) presented CRB in the RCs. Only one patient (0.7%) experienced a UTI. In the EP group, 26 patients (16.8%) experienced multiple ICs (including 2 cases of sepsis) (P < .005). The estimated total cost, including the management of the ICs, was €57,076 with EP versus €4802.33 with GP. The average cost per patient with EP was € 368.23 versus €33.11 with GP. GP achieved an estimated total savings of € 52,273.67. Six patients had to undergo GP to prevent an IC. Conclusions: GP is associated with a marked decrease in the incidence of ICs caused by CRB and reduced healthcare costs

Implantación laparoscópica de esfínter urinario artificial: una opción en el tratamiento de la incontinencia urinaria femenina recidivada / Laparoscopic implantation of artificial urinary sphincter: An option for treating recurrent female urinary incontinence

Introducción: El fallo de la cirugía anti-incontinencia oscila entre el 5-80%. En la actualidad no existe consenso sobre el uso del esfínter urinario artificial (EUA) como tratamiento de la incontinencia urinaria recidivada en la mujer. Varios autores han demostrado que el EUA es útil si se comprueba la deficiencia intrínseca del esfínter. Presentamos, a nuestro entender, el primer caso descrito en España sobre la implantación laparoscópica de un EUA como tratamiento de la incontinencia urinaria recidivada femenina. Material y métodos: Bajo anestesia general se colocó a la paciente en decúbito supino con ligero Trendelenburg y se comprobó el acceso a la vagina. Mediante un abordaje laparoscópico pélvico transperitoneal se desarrolló el espacio de Retzius y seguidamente los espacios laterovaginales hasta la fascia endopélvica. Para facilitar la disección del cuello vesical se introdujo una torunda en la vagina, realizando maniobras simultáneas de tracción y contratracción. Como puerta de entrada para el EUA se amplió la incisión del trocar inferior. Se ajustó el manguito periuretral y seguidamente se colocan: el reservorio y la bomba en el espacio latero-vesical y el labio mayor de la vulva respectivamente. Finalmente, se conectaron los 3 elementos del EUA y se cerró el peritoneo para aislarlo del intestino. Resultados: Tiempo operatorio: 92 min. Pérdida hemática estimada < 100 cc3. Estancia hospitalaria: 48 h. No ocurrieron complicaciones intra ni postoperatorias. El EUA se activó a las 6 semanas. A los 24 meses la paciente lo manipula adecuadamente y alcanzó continencia total. Conclusiones: La implantación laparoscópica del EUA es una técnica factible. Las maniobras transvaginales de tracción y contratracción pueden evitar lesiones intraoperatorias

Introduction: The failure rate for anti-incontinence surgery ranges from 5% to 80%. There is not actual consensus on the use of artificial urinary sphincter (AUS) as treatment for recurrent urinary incontinence in women. Several authors have shown that AUS can be useful, if the intrinsic sphincteric deficiency is checked. We present the first case in Spain, to our knowledge, of laparoscopic implantation of AUS as treatment for female recurrent urinary incontinence. Material and methods: Under general anaesthesia, patient was placed in supine decubitus with slight Trendelenburg, access to the vagina was verified. Through a transperitoneal pelvic laparoscopic approach, Retzius space was opened and then the laterovaginal spaces up to the endopelvic fascia. To facilitate the dissection of the bladder neck, we inserted a swab into the vagina, performing simultaneous traction and countertraction manoeuvres. As an access port for the AUS, we widened the incision of the lower trocar. We adjusted the periurethral cuff and then placed the reservoir and the pump in the laterovesical space and the labia majora of the vulva, respectively. Lastly, we connected the 3 AUS elements and peritoneum was closed to isolate AUS from the intestine. Results: The surgical time was 92 min, the estimated blood loss was < 100 cc3 and the hospital stay was 48 h. There were no intraoperative or postoperative complications. The AUS was activated at 6 weeks. At 24 months, patient managed the AUS adequately and total continence was achieved. Conclusions: Laparoscopic implantation of AUS is a feasible technique. Transvaginal traction and countertraction manoeuvres can prevent intraoperative lesions

Giant retroperitoneal sarcoma: case report.

OBJECTIVE: To report a new case of giant retroperitoneal mass with silent beginning. METHODS: We present the case of a 36 year old man with a giant retroperitoneal liposarcoma 35 × 15 cm in size. The only symptom was a one month history of minimal abdominal pain. CONCLUSION: Liposarcoma is the most frequent retroperitoneal mass. In most of the cases clinical symptoms are silent, being this the reason why diagnosis is late and the size is large. The best image options are CT scan or MRI but final diagnosis is based on pathology results. Its treatment is surgery and relapse is very usual.

Liposarcoma retroperitoneal gigante: presentación de un nuevo caso / Giant retroperitoneal sarcoma: case report

OBJETIVO: Presentar un nuevo caso de masa retroperitoneal gigante. MÉTODOS: Se presenta el caso de un varón de 36 años con un liposarcoma retroperitoneal gigante de 35 x 15 cm cuyo único síntoma actual es una molestia abdominal de un mes de evolución. CONCLUSIÓN: El liposarcoma supone la masa retroperitoneal más frecuente, dando lugar en la mayoría de los casos a una sintomatología silente, lo que implica un retraso en su diagnóstico y un gran incremento en su tamaño. Las pruebas de imagen más concluyentes son la Tc o la Rmn pero el diagnóstico de certeza es histológico. Su tratamiento es quirúgico, el objetivo es la exéresis completa pero la recidiva es la norma(AU)

[Role of direct radionuclide cystography and renal study by dimercaptosuccinic acid (DMSA) in the diagnosis and follow-up of vesicoureteral reflux]. / La cistografía isotópica directa y la gammagrafía renal con ácido dimercaptosuccínico (DMSA) en el diagnóstico y seguimiento del reflujo vesicoureteral.

AIM: To evaluate the role of isotopic studies in the diagnosis and follow-up of vesicoureteral reflux (VUR) and to present the results of our current protocol. MATERIAL AND METHODS: Forty three patients with VUR were retrospectively studied with a mean follow-up of 43 years (1-11 years). VUR was diagnosed by voiding cystourethrography and followed-up by direct radionuclide cystography. During the follow-up all patients were studied by means of renal DMSA scintigraphy (21 were also studied during the acute phase of febrile urinary tract infection). RESULTS: Eighty three renal units were examined. Voiding cystourethrography was positive for VUR in 49 renal units (59%; 8 grade I, 18 grade II, 15 grade III, and 8 grade IV). During the follow-up, direct radionuclide cystography showed decrease or disappearance of VUR in 29 renal units (35%; 4 grade I, 16 grade II, 7 grade III, and 2 grade IV). DMSA studies performed during the follow-up showed cortical lesions in 17 renal units (5 with VUR grade II, 7 with grade III, and 5 grade IV). Nine of 21 patients examined by DMSA during the acute phase of febrile urinary tract infection showed cortical damage (43%), and 6 of them (67%) progressed to cortical lesion in the follow-up DMSA. CONCLUSIONS: The present protocol allows for the correct diagnosis and control of VUR, the early detection of acute renal damage, and the control of its evolution.

La cistografía isotópica directa y la gammagrafía renal con ácido dimercaptosuccínico (DMSA) en el diagnóstico y seguimiento del reflujo vesicoureteral / Role of direct radionuclide cystography and renal study by dimercaptosuccinic acid (DMSA) in the diagnosis and follow-up of vesicoureteral reflux

Objetivo: Valorar la utilidad de la cistografía isotópica directa (CID) y de la gammagrafía renal con ácido dimercaptosuccínico (DMSA) en el diagnóstico y seguimiento del RVU, según los resultados obtenidos a partir del protocolo actual de nuestro centro. Material y Métodos: Se han estudiado retrospectivamente 43 pacientes diagnosticados de RVU con un período de seguimiento medio de 4 ñ 3 años (1-11 años). El diagnóstico de RVU se realizó mediante cistografía radiológica (CUMS) y el seguimiento mediante CUMS y/o CID. Durante el seguimiento se realizó gammagrafía renal con DMSA a todos los pacientes. Veintiún pacientes también fueron estudiados con DMSA durante la fase aguda de la infección urinaria febril. Resultados: Se exploraron 83 unidades renales. En el momento del diagnóstico la CUMS fue positiva para RVU en 49 unidades renales (59 per cent; 8 grado I, 18 grado II, 15 grado III y 8 grado IV). Durante el seguimiento por CID se observó disminución o desaparición del RVU en 29 unidades renales (35 per cent; 4 grado I, 16 grado II, 7 grado III y 2 grado IV). Durante el seguimiento el DMSA mostró lesiones corticales en 17 unidades renales (5 con RVU grado II, 7 grado III y 5 grado IV). Nueve de los 21 pacientes estudiados con DMSA durante la fase aguda de la infección urinaria febril presentaron afectación cortical (43 per cent), de los cuales 6 evolucionaron a lesión cortical en el DMSA de control (67 per cent). Conclusiones: El protocolo descrito permite diagnosticar y controlar el RVU, identificar precozmente la afectación renal y controlar su evolución (AU)

Bladder neoplasms after nephroureterectomy: does the surgery of the lower ureter, transurethral resection or open surgery, influence the evolution?

OBJECTIVE: Nephroureterectomy is the treatment of choice for tumors of the upper urinary tract (UUTT). In 1952, a modified version of this technique was described, involving endoscopic detachment of the ureter followed by nephroureterectomy with a single lumbar incision. We reviewed a retrospective survey to assess whether UUTT patients treated with nephroureterectomy with no prior history of bladder tumor had different rates of incidence or different sites of bladder recurrence according to the specific technique employed. METHODS: Patients were divided into group A, 87 patients who underwent a double incision nephroureterectomy and group B with 58 patients with prior detachment of the ureter. In both groups, incidence was calculated for two variables (bladder tumor recurrences and homolaterality of such recurrences) and chi-square tested. RESULTS: Bladder tumor was diagnosed at follow-up in 39% of patients in group A and 34.5% in group B, with no statistically significant difference (N.S.). Bladder tumor recurrences were homolateral to UUTT in 50% of group A cases and 55% of group B cases (N.S.). CONCLUSIONS: Although this is a retrospective survey of two asynchronous groups, given the similar nature of the UUTT cases in both groups and the fact that no statistically significant differences have been found, it is reasonable to conclude that nephroureterectomy with prior endoscopic detachment of the ureter is a safe and radical procedure.

[Cytoscopic follow-up of initial G3T1 bladder tumors treated with BCG]. / Seguimiento cistoscópico de los tumores vesicales G3T1 iniciales tratados con BCG.

OBJECTIVE: To evaluate the cystoscopic findings during initial follow-up, the anatomopathological correlation of tumor endoscopic features and the results of standard control multiple biopsy performed 6 months after TUR in patients with G3T1 transitional carcinoma treated with BCG. METHODS: 114 patients with G3T1 bladder tumor (52% associated with Cis) were treated with 81 mg Connaught BCG intravesical instillations weekly for 6 consecutive weeks. Follow-up was performed with cystoscopy and cytology at 3 months, and cystoscopy and standard multiple biopsy at 6 months. The endoscopic findings were described as normal bladder, macroscopically tumorous lesion or erythematous lesion. RESULTS: During the first 6 months of follow-up superficial recurrence was found in 16% and 5% showed progression to muscle invasion. Tumor recurrence or progression was found in 61% and 39% at 3 and 6 months, respectively. Most of the macroscopically tumorous lesions resulted in a tumor at 3 and 6 months in 56% and 64%, respectively, and the remaining lesions were mainly inflammatory granulomas produced by BCG therapy. Twenty biopsies of erythematous areas detected only one case of Cis (5%) and 98 standard multiple biopsies of endoscopically normal mucosa detected 10 cases of Cis (overall, 3 at 3 months and 7 at 6 months); all cases were preceded by initial Cis except in one case. CONCLUSIONS: Cystoscopy performed at 3 months is very useful since it detected 61% of the superficial recurrences and 66% of the cases with progression to muscle invasion during the first 6 months. Routine biopsy of erythematous areas detected during cystoscopy is of little value since a large number of these biopsies are unnecessary in view of its diagnostic yield (5%). Since 90% of the Cis detected during the first 6 months of follow-up were patients with Cis in the initial tumor, it would be appropriate to perform standard multiple biopsy for control only in this subgroup of patients if the sensitivity of cytology is low in high grade tumors or Cis.
