Estenosis arterial del injerto renal: evaluación de la incidencia mediante ecografía doppler, factores de riesgo y análisis de las complicaciones que pueden afectar a la supervivencia del injerto / Transplant renal artery stenosis: Study of incidence using doppler ultrasound, risk factors and analysis is effect in graft outcomes

Introducción y objetivos La estenosis de la arteria del injerto renal (EAR) es una complicación vascular del trasplante renal cuya incidencia estimada es del 13%, la cual puede causar hipertensión arterial refractaria, disfunción renal y muerte prematura en los receptores. Métodos Se realizó un estudio retrospectivo que incluyó a todos los pacientes sometidos a trasplante renal entre 2014 y 2020. Los pacientes fueron evaluados mediante ecografía doppler renal sistemática tras el trasplante. Para identificar los factores de riesgo independientes de la estenosis de la arteria renal tras el trasplante, realizamos un análisis multivariante. Resultados Se incluyeron 724 trasplantes renales, el 12% eran de donante vivo y el 88% de donante fallecido. La edad media en los receptores era de 54,8 años y en los donantes era de 53. Se diagnosticó estenosis de la arteria del injerto renal en 70 (10%) receptores, la mayoría durante los primeros 6 meses después de la intervención. El 51% de los pacientes con estenosis de la arteria del injerto renal se manejaron de manera conservadora. El análisis multivariante mostró que la diabetes mellitus, el rechazo del injerto, la resutura arterial y el índice de masa corporal del donante eran factores de riesgo independientes de estenosis de la arteria renal después del trasplante. La supervivencia de los injertos con estenosis de la arteria del injerto renal fue del 98% a los 6 meses y del 95% a los 2 años. Conclusiones El uso sistemático de la ecografía doppler en el período inmediatamente posterior al trasplante permitió diagnosticar un 10% de estenosis de la arteria del injerto renal en nuestra cohorte. A pesar de los factores de riesgo mencionados anteriormente, un seguimiento y tratamiento adecuados podrían reducir el riesgo de pérdida del injerto en pacientes con estenosis de la arteria del injerto renal.

Introduction and objectives Transplant renal artery stenosis (TRAS) is a vascular complication after kidney transplantation which estimated incidence is 13%. It could cause refractory arterial hypertension, kidney dysfunction and premature death in transplant recipients. Methods We carried out a retrospective study including every patient who underwent renal transplantation between 2014 and 2020. They were evaluated with a systematic post-transplant renal Doppler ultrasound. To identify independent risk factors for transplant renal artery stenosis we performed a multivariate analysis. Results Seven hundred twenty-four kidney transplants were included, 12% were living donors and 88% were deceased donors. The mean age was 54.8 in recipients and 53 in donors. Transplant renal artery stenosis was diagnosed in 70 (10%) recipients, the majority in the first 6 months after surgery. The 51% of patients with transplant renal artery stenosis were managed conservatively. The multivariate analysis showed diabetes mellitus, graft rejection, arterial resuture and donor body mass index as independent risk factors for transplant renal artery stenosis. Survival of the grafts with transplant renal artery stenosis was 98% at 6 months and 95% at two years. Conclusions The systematic performance of Doppler ultrasound in the immediate post-transplant period diagnosed 10% of transplant renal artery stenosis in our cohort. Despite the above risk factors, an adequate monitoring and treatment could avoid the increased risk of graft loss in patients with transplant renal artery stenosis. (AU)

INTRODUCCIÓN Y OBJETIVO: La cistectomía radical es una cirugía compleja con una alta tasa de complicaciones, entre ellas las infecciones, conllevando un aumento de la morbimortalidad, estancia hospitalaria y costes. El objetivo de este trabajo es estudiar las infecciones relacionadas con la asistencia sanitaria (IRAS) en estos pacientes, así como de los microorganismos asociados, perfiles de resistencia antibiótica y factores de riesgo. MATERIAL Y MÉTODOS: Estudio prospectivo del 2012 al 2017. Se recogen variables epidemiológicas, comorbilidades y variables quirúrgicas. Se analizan los microorganismos implicados y patrones de susceptibilidad antibiótica. RESULTADOS: Estudio de 122 pacientes. Edad media 67 años (DE:18,42). Estancia hospitalaria media 23,5 días (18,42). Tasa de IRAS del 45%, predominando las infecciones del tracto urinario (43%) y de la herida quirúrgica (31%). Cultivos positivos en el 78,6% de los casos. Mayor aislamiento de Enterococcus (18%) y Escherichia coli (13%). El 43% de los microorganismos presentaban resistencia a la amoxicilina/ampicilina, 23% a las betalactamasas y 36% a las quinolonas. El tratamiento empírico fue adecuado en el 87,5%. Se observa un aumento en la estancia hospitalaria (17 días, p < 0,05) por padecer una IRAS. Menor tasa de complicaciones infecciosas en el abordaje laparoscópico frente al abierto (p < 0,001) y en las derivaciones ortotópicas frente al conducto ileal (p = 0,04). CONCLUSIONES: Encontramos una elevada tasa de IRAS en nuestra serie de cistectomías radicales, con un predominio de infecciones del tracto urinario y de la herida quirúrgica. E. coli y Enterococcus spp. son los microorganismos más frecuentemente aislados, con altas tasas de resistencia a algunos antibióticos de uso común

INTRODUCTION AND OBJECTIVE: Radical cystectomy is a complex surgery with a high rate of complications including infections, which lead to increased morbidity and mortality, longer hospital stay and higher costs. The aim of this work is to evaluate health care-associated infections (HAIs) in these patients, as well as associated microorganisms, antibiotic resistance profiles and risk factors. MATERIAL AND METHODS: Prospective study from 2012 to 2017. Epidemiologic variables, comorbidities and surgical variables are collected. The microorganisms involved and antibiotic susceptibility patterns are analyzed. RESULTS: 122 patients. Mean age 67 (SD:18,42). Mean hospital stay 23.5 days (18.42). HAIs rate of 45%, with predominant urinary tract infections (43%) and surgical wound infections (31%). Positive cultures in 78.6% of cases. Increased isolation of Enterococcus (18%) and Escherichia coli (13%). Forty-three percent of microorganisms were resistant to amoxicillin/ampicillin, 23% to beta-lactamases and 36% to quinolones. Empirical treatment was adequate in 87.5%. Hospital stay is increased (17 days, p < 0.05) due to HAIs. Lower rate of infectious complications in the laparoscopic vs. open approach (p < 0.001) and in orthotopic vs. ileal conduit diversion (p = 0.04) CONCLUSIONS: We found a high rate of HAIs in our radical cystectomy series, with predominant urinary tract and surgical wound infections. E.coli and Enterococcus spp. are the most frequently isolated microorganisms, with high rates of resistance to some commonly used antibiotics

Cirugía urológica durante la pandemia por SARS-CoV-2. Análisis descriptivo de la experiencia en un Servicio de Urología durante distintas fases epidemiológicas / Urological surgery during SARS-CoV-2 pandemic. Descriptive analysis of the experience in a Urology Department across the pandemic phases

INTRODUCCIÓN: La pandemia por SARS-CoV-2 ha cambiado la práctica urológica a nivel mundial. Nuestro objetivo es describir los resultados en salud observados en los pacientes intervenidos en el Servicio de Urología de un hospital terciario, a lo largo de diferentes fases epidemiológicas. MÉTODOS: Estudio de cohortes observacional que incluye todos los pacientes intervenidos entre el 1 de marzo y el 14 de mayo. Según la organización hospitalaria, distinguimos 3 periodos: durante las primeras 2 semanas no hubo cambios (1.er periodo), en las 7 semanas siguientes solo se realizaron intervenciones urgentes previa extracción de exudado nasofaríngeo (2.o periodo), y tras el 4 de mayo se reanudó la cirugía electiva aplicando un protocolo de cribado multidisciplinar (3.er periodo). Las variables demográficas y basales, las quirúrgicas y perioperatorias, así como los resultados postoperatorios, se obtuvieron de forma retrospectiva (periodos 1 y 2) y prospectiva (periodo 3). El seguimiento telefónico se realizó al menos 3 semanas tras el alta hospitalaria. RESULTADOS: Se realizaron 103 cirugías urológicas y fueron diagnosticados de COVID-19 11 pacientes, 8 de ellos en el 1.er periodo. El diagnóstico era conocido en un paciente, mientras que los otros 10 desarrollaron la enfermedad en una media de 25 días tras la intervención y 16,6 días tras el alta. Cuatro de 7 pacientes trasplantados resultaron afectados. Se registraron 3 muertes por la enfermedad: una mujer de 69 años trasplantada y 2 varones mayores de 80 años con comorbilidades y alto riesgo anestésico a los que se realizó drenaje de absceso retroperitoneal y cirugía retrógrada intrarrenal, respectivamente. CONCLUSIONES: La infección por SARS-CoV-2 afectó principalmente a trasplantados renales o pacientes añosos con alto riesgo anestésico, durante las 2 primeras semanas de la pandemia. Tras implantar la PCR preoperatoria y un protocolo completo de cribado, los casos se redujeron de manera sustancial y se pudo operar con seguridad

INTRODUCTION: The SARS-CoV-2 pandemic has changed the urological practice around the world. Our objective is to describe the outcomes presented by patients undergoing surgery in the urology department of a tertiary hospital, across the pandemic phases. METHODS: Observational, cohort study including all patients undergoing surgery from March 1 to May 14. According to the hospital organization, we identified three periods: there were no changes during the first two weeks (1st. period), the following seven weeks, when only urgent interventions were carried out after performance of nasopharyngeal swab test (2nd. period), and finally, elective surgery was resumed on May 4, after the implementation of a multidisciplinary screening protocol (3rd. period). Demographic, baseline, surgical and perioperative variables, as well as postoperative outcomes, were obtained in a retrospective (periods 1 and 2) and prospective (period 3) manner. Telephone follow-up was initiated at least 3 weeks after hospital discharge. RESULTS: 103 urological surgeries were performed, and 11 patients were diagnosed with COVID-19, 8 of them within the 1st. period. The diagnosis was already known in 1 patient, while the other 10 developed the disease in an average of 25 days after the intervention and 16,6 days after discharge. Of seven transplant patients, four got the infection. Three deaths were recorded due to the disease: a 69-year-old woman transplanted and two men over 80 with comorbidities and high anesthetic risk who underwent drainage of retroperitoneal abscess and retrograde intrarenal surgery, respectively. CONCLUSIONS: SARS-CoV-2 infection mainly affected renal transplant recipients or elderly patients with high anesthetic risk, during the first 2 weeks of the pandemic. After implementing preoperative PCR tests and a comprehensive screening protocol, cases were substantially reduced, and safe surgical procedures were achieved

Infecciones relacionadas con la asistencia sanitaria en pacientes ingresados en un servicio de Urología: patrones de resistencia y adecuación del tratamiento antibiótico empírico como factor pronóstico / Infections related to healthcare in patients hospitalized in a Urology service: Resistance patterns and adequacy of empirical antibiotic treatment as a prognostic factor

Objetivos: Evaluar la idoneidad de la antibioterapia empírica en IRAS y los patrones de resistencia a antibióticos de los microorganismos responsables, así como la incidencia de mortalidad y factores de riesgo en relación con IRAS. Método: Durante un periodo de 4 años se realiza un estudio prospectivo observacional sobre todos los pacientes de ambos sexos y mayores de 16 años ingresados por cualquier proceso urológico. Se evalúan la incidencia y las características de las IRAS y se analiza el microorganismo causante y sus resistencias, la antibioterapia empírica inicial y si esta precisó modificación, y las tasas de mortalidad. Resultados: De un total de 6.546 pacientes, el 6,3% sufrieron IRAS, correspondiendo el 70,5% a infección del tracto urinario y el 22,1% a infección de la herida quirúrgica. E. coli, Enterococcus spp., Klebsiella spp. y P. aeruginosa fueron los más frecuentemente implicados (25,1, 17,5, 13,5 y 12,3%, respectivamente). E. coli y Klebsiella spp. fueron productoras de betalactamasas de espectro extendido (BLEE) en el 24,7 y el 47,8%, respectivamente. El 4,3% de Klebsiella y el 33,3% de Pseudomonas eran resistentes a carbapenemes. La resistencia global a quinolonas fue del 50% aproximadamente. Los antibióticos más frecuentemente usados de forma empírica fueron cefalosporinas de tercera y cuarta generación (33,6%) y carbapenemes (28,2%). Se obtuvo una tasa global de adecuación de antibioterapia empírica del 82,9%. La tasa de mortalidad en los pacientes con IRAS fue del 2,2%, frente al 0,3% en los pacientes sin infección. En un análisis multivariable, las variables que se asociaron a mayor riesgo de mortalidad fueron el aislamiento de enterobacterias productoras de BLEE y el tratamiento antibiótico empírico inadecuado. Conclusiones: La selección de la antibioterapia empírica fue bastante precisa. Se está observando un aumento de IRAS por microorganismos multirresistentes, como enterobacterias BLEE o P.aeruginosa multirresistentes. El riesgo de mortalidad aumenta con una antibioterapia empírica inicial inadecuada o cuando el microorganismo responsable es una enterobacteria BLEE

Objectives: To evaluate the suitability of empirical antibiotic therapy in HAIs and the antibiotic resistance patterns of the responsible microorganisms, as well as the incidence of mortality and risk factors involved. Method: A prospective observational study was carried out on patients of both sexes older than 16 years, admitted by any urological process during a period of 4 years. The incidence and characteristics of HAIs, as well as the causative organism and its resistance, the initial empirical antibiotic therapy and its modification, if required, and mortality rates are analyzed. Results: Out of 6546 patients, 6.3% suffered HAIs, 70.5% corresponding to urinary tract infection and 22.1% to infection of the surgical wound. E.coli, Enterococcus spp., Klebsiella spp. y P. aeruginosa were the most frequently implicated (25.1%, 17.5%, 13.5% and 12.3%, respectively). E. coli and Klebsiella spp. were producers of extended-spectrum beta-lactamases (ESBL) in 24.7% and 47.8%, respectively. 4.3% of Klebsiella and 33.3% of Pseudomonas were carbapenems-resistant. The overall resistance to quinolones was approximately 50%. The most commonly used antibiotics for empirical therapy were cephalosporins of 3rd and 4th generation (33.6%) and carbapenems (28.2%). An overall rate of adequacy of empirical antibiotic therapy of 82.9% was obtained. The mortality rate in patients with HAIs was 2.2%, compared with 0.3% in patients without infection. In a multivariate analysis, the variables associated with the highest mortality risk were the isolation of ESBL-producing enterobacteria and the inadequate empirical antibiotic treatment. Conclusions: The selection of empirical antibiotic therapy was quite accurate. An increase in HAIs by multiresistant microorganisms, such as ESBL Enterobacteria or multiresistant P.aeruginosa is being observed. The mortality risk increases with inadequate initial empirical antibiotic therapy or when the responsible microorganism is an ESBL enterobacteria

Donantes en asistolia no controlada (tipos I-II) con recirculación normotérmica versus donantes en muerte cerebral: evaluación de resultados funcionales y supervivencia / Uncontrolled non-heartbeating donors (types I-II) with normothermic recirculation vs. heartbeating donors: Evaluation of functional results and survival

Objetivo: El donante en asistolia (DA) es una alternativa al donante en muerte cerebral (DMC). Nuestro objetivo es comparar los resultados funcionales y la supervivencia de riñones procedentes de DA y DMC. Material y métodos: Realizamos un estudio retrospectivo comparando los resultados de 236 riñones de DA tipos i y ii preservados en normotermia con 250 procedentes de DMC, trasplantados en nuestro centro entre 2005 y 2012. Se comprueba la homogeneidad entre grupos y evaluamos si la presencia de retraso en la función del injerto (RFI) de asocia a las variables pretrasplante de donante y receptor. Resultados: Ambos grupos muestran homogeneidad en las características pretrasplante en cuanto a: edad, incompatibilidades HLA, tiempo del receptor en hemodiálisis. El tiempo medio de seguimiento es de 33 meses (rango 0-87) los DA y 38 meses (rango 0-90) para DMC. Los DA mostraron un 5,5% de no función primaria (NFP) frente a un 4% en los DMC (p = 0,42) y un 80,9% de RFI frente a un 46,8% de los DMC (p < 0,001). Al final del seguimiento, no hubo diferencias estadísticamente significativas en la supervivencia del injerto (92,8% DA vs. 93,6% DMC, p = 0,71) y receptores (99,1% DA vs. 98,6% DMC, p = 0,28). Conclusiones: Aunque el porcentaje de RFI es mayor para los DA, tanto la creatinina final como la supervivencia del injerto y el receptor son similares para ambos grupos. Por tanto, en nuestra experiencia los riñones procedentes de DA tienen resultados similares a aquellos de DMC y constituyen una excelente fuente de órganos para trasplante

Objective: Non-heartbeating donors (NHBD) are an alternative to heartbeating donors (HBD). Our objective was to compare functional results and kidney survival from NHBDs and HBDs. Material and methods: A retrospective study comparing the results of 236 normothermically preserved kidneys from type i and ii type NHBDs with the results of 250 from HBDs that were transplanted in our center between 2005 and 2012. Homogeneity between groups was tested and we evaluated the presence of delayed graft function (DGF) associated with pretransplant variables of the donor and recipient. Results: Both groups show homogeneity in pretransplant characteristics in terms of: age, HLA incompatibilities, and recipient hemodialysis time. Average follow-up time was 33 months (range 0-87) for NHBDs and 38 months (range 0-90) for HBDs. 5.5% of NHBDs showed primary non-function (PNF) vs. 4% of HBDs(P=.42) and 80.9% of DGF vs. 46.8% of HBDs (P<.001). At the end of the follow-up, there were no statistically significant differences in the survival of grafts (92.8% for NHBD vs. 93.6% for HBD, P=.71) and recipients (99.1% NHBD vs. 98.6% HBD, P=.28). Conclusions: Although the DGF percentage was greater for NHBDs, final creatinine as well as graft and recipient survival were similar for both groups. Therefore, in our experience, kidneys from NHBDs have similar results to those from HBDs and are an excellent source of organs for transplantation

Dual kidney transplantation involving organs from expanded criteria donors: a review of our series and an update on current indications.

BACKGROUND: Our purpose was to review our kidney transplantation program based on the use of expanded criteria donors, and to determine current indications for dual kidney transplantation (DKT). In 1996, a program was initiated to transplant kidneys from donors of over 60 years performing single or dual transplantation. METHODS: In 1996, a program was initiated to transplant kidneys from donors of over 60 years performing single or dual transplantation. DKT were performed with donors >75 and donors between 60 and 74 years of age and glomerulosclerosis of >15%. The kidneys of donors between 60 and 74 years of age and with glomerulosclerosis of <15% were used for single kidney transplantation (SKT). In 2005, we started to perform SKT despite glomerulosclerosis being >15%, taking into account donor and recipient characteristics. RESULTS: From 1996 to 2004, 222 SKTs and 88 DKTs were performed. Graft survival after 1 and 4 years was, respectively, 91% and 78% for SKT and 95% and 79% for DKT. In 2005, we started to perform SKT despite glomerulosclerosis being >15%, taking into account donor and recipient characteristics. From 2005 to 2011, 328 SKT and 32 DKT were performed. During this period most kidneys used for DKT were from female donors >75 years old, weighing <65 kg, with a creatinine of >1 mg/dL and glomerulosclerosis of >15%. The recipients for DKT were mostly male, <70 years old and whose weight was >75 kg. CONCLUSION: DKT from expanded criteria donors shows good outcomes. However, in many cases SKT may fulfill the need of the recipient. The archetype for DKT is an older female weighing <65 kg and the most common recipient is an overweight male who is <70 years old.

Cistectomía laparoscópica y derivación urinaria continente intracorpórea (Mainz II) en el tratamiento de la cistitis intersticial / Laparoscopic Cystectomy and Intracorporeal Continent Urinary Diversion (Mainz II) in Treatment for Interstitial Cystitis

Introducción: La cistitis intersticial (CI) es una enfermedad de difícil manejo y de curso crónico e insidioso. Presentamos una serie de pacientes diagnosticadas de CI sin respuesta al tratamiento conservador, sometidas a cistectomía total con ureterectomía y derivación urinaria continente (Mainz II ) laparoscópica totalmente intracorpórea, como alternativa radical al tratamiento de esta enfermedad. Material y métodos: Entre enero de 2001 y abril de 2009 se operaron 8 pacientes que cumplían criterios clínicos y de exclusión para CI según el National Institute of Health y en las cuales había fracasado el tratamiento conservador. Se realizó un análisis descriptivo de la serie con las siguientes variables: edad, riesgo quirúrgico según la Sociedad Americana de Anestesiología (ASA), tiempo quirúrgico (TQ) total, TQ de la cistectomía, TQ de la derivación, complicaciones tempranas y tardías, tiempo de ingreso, sangrado y necesidad de transfusión, vía de extracción de la pieza y conservación del útero. Resultados: La edad media fue 54,25 (± 17,8) años, el TQ medio total 286,4 min (± 44,8), el TQ medio de la cistectomía 86,2 min (± 25,6), el TQ medio de la derivación 123,7 min (± 28,6), el sangrado medio 321,4 cc (± 242,9) y el tiempo medio de ingreso 8,3 días (± 1,3). El 50% era un ASA I, el 37,5% ASA II y el 12,5% ASA III. En el 50% de los casos se realizó una histerectomía. En 5 casos (62,5%) se extrajo la pieza por el recto y en 3 casos (37,5%) por la vagina. La única complicación precoz fue una sepsis. No hubo conversión en la serie. Conclusiones: La cistectomía total con ureterectomía y derivación urinaria continente por vía laparoscópica e intracorpórea es una alternativa eficaz y definitiva para el tratamiento de la CI rebelde al tratamiento conservador. Su dificultad técnica y su curva de aprendizaje limitan su reproducibilidad a centros con importante experiencia laparoscópica

Introduction: Interstitial cystitis (IC) is a difficult-to-manage chronic and insidious condition. We present a series of patients with IC who failed to respond to conservative treatment. The patients underwent total cystectomy with completely intracorporeally performed continent urinary diversion (Mainz II rectosigmoid pouch) as a radical alternative to the treatment of this condition. Material and methods: Eight patients who fulfilled the clinical criteria for IC according to the National Institute of Health and in whom all previous conservative treatments had failed between January 2001 and April 2009 were operated on. A descriptive analysis was made with the following variables: age, surgical risk according to the American Society of Anesthesiology(ASA), total surgical time (ST), ST of the cystectomy, ST of the urinary diversion, early and late complications, time of hospital stay, bleeding and need of transfusion, specimen extraction pathway and uterine sparing. Results: Mean age was 54.25 (±17.8) years, total mean ST 286.4 (±44.8) minutes, mean ST of the cystectomy 86.2 (±25.6) minutes, mean ST of the diversion 123.7 (±28.6) minutes, mean bleeding 321.4 (±242.9) cc, mean time of hospital stay 8.3 (±1.3) days. Fifty percent were ASA I, 37.5% ASA II and 12.5% ASA III. A hysterectomy was made in 50% of the cases. In 5 cases (62.5%) the bladder was extracted through the rectum and in 3 cases (37.5%) through the vagina. The only early complication was urinary sepsis in one patient. There was no conversion in the series. Conclusions: Total cystectomy with urethrectomy and intracorporeal continent urinary diversion is an effective and definitive alternative for the treatment of treatment resistant IC. Their technical difficulty and its learning curve limit their application to centers with an extensive experience in laparoscopy

Laparoscopic cystectomy and intracorporeal continent urinary diversion (Mainz II) in treatment for interstitial cystitis.

[An analysis of the value of bowel preparation for preventing postoperative complications in endoscopic surgery]. / Análisis de la utilidad de la preparación intestinal en la prevención de complicaciones postoperatorias en cirugía endoscópica.

OBJECTIVES: To assess the relationship between mechanical preparation of the bowel before endourological surgery and the occurrence of postoperative complications. MATERIALS AND METHODS: A prospective, randomized study was conducted in 162 patients undergoing TUR of the bladder, TURP, and lase adenomectomy from October 2008 to February 2009. No patient was excluded. An enema was administered before surgery to 66 patients, but not to the remaining patients. Variables analyzed included occurrence of urinary tract infection (UTI), fever, acute urinary retention (AUR), postoperative need for enemas or laxatives, surgical field contamination, and mean hospital stay. A descriptive analysis, a means comparison (t test), and a Chi-square test were performed. RESULTS: Mean patient age was 70.5 years (SD+/-10.62), and mean hospital stay 4.8 days (SD+/-3.9). UTI occurred in 6.2% of patients, fever in 3.1%, and AUR in 1.2%, and 15.4% of patients required enemas or laxatives. Fecal contamination of the surgical field was found in one patient (0.6%). There were no statistically significant differences between the study groups in the variables analyzed. CONCLUSIONS: In our series, bowel preparation using enema has shown no value for decreasing postoperative complications of endourological surgery.

Objetivos: Determinar la relación entre la preparación mecánica intestinal previa a la cirugía endourológica y la existencia de complicaciones postoperatorias. Material y métodos: Diseñamos un estudio prospectivo y aleatorizado con 162 pacientes intervenidos mediante RTU vesical, RTU prostática y adenomectomía láser entre octubre de 2008 y febrero de 2009, sin excluir a ningún paciente. A 66 pacientes se les administró un enema previo a la cirugía y a los restantes no. Analizamos la incidencia de infección urinaria (ITU), fiebre, retención aguda de orina, necesidad de enemas o laxantes durante el postoperatorio, contaminación del campo quirúrgico y la estancia media. Realizamos un análisis descriptivo, comparación de medias (t test) y chi cuadrado. Resultados: La edad media fue de 70,5 años (DS±10,62) y la estancia media fue de 4,8 días (DS±3,9). Un 6,2% de los pacientes tuvo ITU, un 3,1% tuvo fiebre, un 1,2% presentó retención aguda de orina y el 15,4% necesitó enemas o laxantes. Se recogió un caso de contaminación con heces del campo quirúrgico (0,6%). No se encontraron diferencias estadísticamente significativas para las variables analizadas entre ambos grupos de estudio. Conclusiones: En nuestra serie, la preparación intestinal mediante el empleo de enemas no ha demostrado utilidad para disminuir complicaciones durante el postoperatorio de cirugía endourológica (AU)
