RESUMO

OBJECTIVE: Although an immediate postoperative instillation of chemotherapy (IPOIC) after transurethral resection of bladder tumors (TURBT) is recommended for the prevention of recurrences of non-muscleinvasive bladder cancer (NMIBC), evidence shows there is an important compliance failure worldwide. We believe that an immediate neoadjuvant instillation of chemotherapy (INAIC) can act similarly, reducing the recurrence risk of NMIBC. Here we present the interim analysis of the PRECAVE clinical trial. MATERIAL AND METHODS: Patients with clinically diagnosed NMIBC were randomized to receive an INAIC with mitomycin C before TURBT (Group A) or to a control group with TURBT only (Group B). Primary end point was to compare the efficacy of an INAIC in the early recurrence-free survival (RFS). Secondary end points were: RFS in patients who did not receive adjuvant treatments, toxicity, and feasibility. RESULTS: A total of 124 patients with Ta/T1 G1-G3NMIBC were included in the initial analysis (Group A:64, Group B: 60). Demographics, risk classification, complications, and adjuvant treatments were balanced between groups. Eighty-four patients (Group A: 45, Group B: 39) who completed a one-year follow-up were included in the efficacy analysis and no difference was observed in the RFS between groups (p=0.3). In the subgroup of patients who did not receive adjuvant treatments, we found a significant difference in favor of an INAIC (p=0.009) and an 80% reduction in the risk of early recurrences (Hazard Ratio: 0.20; 95% confidence interval: 0.05-0.81; p=0.0024). No differences were observed in adverse events. Only 4 patients did not receive an INAIC despite being planned. CONCLUSIONS: In this interim analysis, although we could not demonstrate a reduction in the RFS of all patients, we did find a significant decrease of recurrences in patients who did not receive adjuvant treatments. The administration of an INAIC seems to be safe and our protocol appears feasible and reproductive.


OBJETIVO: Aunque el uso de una instilación postoperatoria inmediata de quimioterapia (IPOIQ) tras una resección transuretral vesical (RTUV) esta recomendada para prevenir recurrencias de carcinoma vesical no músculo invasivo (CVNMI), no se llega a realizar en muchos casos debido a fallos en su cumplimiento. Nosotros creemos que una instilación neoadyuvante inmediata de quimioterapia (INAIQ) puede actuar de manera similar reduciendo el riesgo de recurrencias. Presentamos el análisis intermedio del ensayo clínico PRECAVE.MATERIAL Y MÉTODOS: Se aleatorizó a pacientes diagnosticados de CVNMI a recibir una INAIQ con mitomicina C antes de la RTUV (Grupo A) o a un grupo control con RTUV solamente (Grupo B). El objetivo primario fue comparar la eficacia de una INAIQ en la supervivencia libre de recurrencia (SLR) temprana. Los objetivos secundarios fueron la SLR en pacientes que no recibieron tratamientos adyuvantes, toxicidad y viabilidad. RESULTADOS: Analizamos un total de 124 pacientes con CVNMI Ta/T1G1-G3 fueron analizados (Grupo A:64, Grupo B: 60). No se encontraron diferencias entre datos demográficos, grupos de riesgo, complicaciones o tratamientos adyuvantes. Para el análisis de eficacias e incluyeron 84 pacientes (Grupo A: 45, Grupo B:39) con al menos un año de seguimiento, sin observar diferencias en la SLR (p=0,3). Sin embargo, en el subgrupo que no recibió tratamientos adyuvantes, sí encontramos una diferencia significativa a favor de la INAIQ (p=0,009), y una reducción del riesgo de recurrencias tempranas del 80% (Hazard Ratio: 0,20; intervalo de confianza 95%: 0,05-0,81; p=0,0024). No se observaron diferencias en la aparición de eventos adversos. Solo 4 pacientes no recibieron un INAIC a pesar de estar planificado. CONCLUSIONES: En este análisis intermedio, aunque no pudimos demostrar una reducción en la SLR de todos los pacientes, sí encontramos una diferencia en el subgrupo que no recibió tratamientos adyuvantes. La administración de una INAIC parece ser segura, y nuestro protocolo parece factible y reproducible.

RESUMO

INTRODUCTION: Patients affected by von Hippel-Lindau (VHL) disease experience an increased risk for bilateral, synchronous, and metachronous renal cell carcinoma (RCC). Oncologic and functional outcomes are the main goals in the management of renal masses. We present our protocol for patients with VHL disease-associated RCC alongside functional and oncologic results observed in our series. MATERIAL AND METHODS: We performed a retrospective analysis of our clinical database of patients with VHL disease-associated RCC referred to our department between June 2005 and December 2017. We offer surveillance for lesions <2 cm and active management with radiofrequency ablation (RFA) for lesions 2-3 cm, and nephron-sparing surgery (NSS), RFA or embolization techniques for lesions >3 cm or growth rate >1 cm/year. RESULTS: Our series comprises 14 patients, of whom 13 had undergone at least one invasive procedure for RCC, mean age at first intervention was 27 years (range 18-60). Overall, 30 interventions were performed in 21 kidneys: four radical nephrectomies, 13 RFAs, 12 NSSs, and one embolization. During follow-up (median time: 41 months, range: 6-149), eight patients (57%) presented with new lesions that required treatment, with a mean time between treatments of 32 ±18.5 months. No metastatic progression or need for dialysis was recorded; the success rate for RFA was 85%. CONCLUSIONS: Management of VHL kidney disease by NSS is the standard of care with a cut-off at 3 cm, ablative procedures should be offered to lesions ranging 2-3 cm in size. Follow-up should be done strictly in referral centers that can provide all treatment options to renal function and control oncologic progression.

RESUMO

There are multiple definitions of high risk prostate cancer and each definition is associated with a different prognosis. Men classified as having high-risk disease warrant treatment because durable outcomes can be achieved. Radical prostatectomy, radiation therapy and androgen deprivation therapy play pivotal roles in the management of men with high-risk disease, and potentially in men with metastatic disease.


Hay múltiples definiciones del cáncer de próstata de alto riesgo y cada definición se asocia con un pronóstico diferente. En varones con cáncer de próstata clasificado cómo enfermedad de alto riesgo se justifica el tratamiento porque se pueden conseguir resultados duraderos. La prostatectomía radical, la  radioterapia y el tratamiento de deprivación androgénica juegan un papel fundamental en el manejo de los pacientes con enfermedad de alto riesgo, y potencialmente en varones con enfermedad metastásica.

RESUMO

Androgen deprivation therapy is part of the initial treatment of patients with metastatic prostate cancer. Nevertheless, after an initial response and despite maintaining an effective testosterone suppression, the tumor is able to continue growing.Enzalutamide is an oral second generation pure antiandrogen that acts at various levels in the signal activation cascade of the androgen receptor and has demonstrated being effective in this phase of the disease. In the clinical trials completed, it has demonstrated benefits in overall patient survival in patients with the diagnosis of metastatic castration resistant prostate cancer. Recent studies have also demonstrated benefits in progression free survival in patients with non-metastatic castration resistant prostate cancer. Enzalutamide has an excellent toxicity profile, but we have to avoid it in patients with history of seizure episodes, mainly if they are under anti-epileptic drug therapy. Enzalutamide is rapidly metabolized by the liver, mainly through the CYP2C8 and to a lesser extent by CYP3A4/5 so that its metabolism may be altered when cytochrome isoenzyme inductor or inhibitor drugs are given concomitantly. Moreover, enzalutamide may require dose adjustment for other drugs since it is a potent inductor of CYP3A4 and a moderate inductor of CYP2C9 y el CYP2C19. Even though treatment with enzalutamide has significantly altered the natural history of the disease, in most cases it will progress by development of resistance mechanisms, among which we may emphasize androgen receptor mutations, overexpression, amplification and variants, as well as the intracrine production of androgens. Enzalutamide must be considered as first line therapy in patients with castration resistant prostate cancer.

RESUMO

La terapia de deprivación androgénica forma parte del tratamiento inicial de los pacientes con cáncer de próstata metastásico. Sin embargo, tras una respuesta inicial y a pesar de mantener una supresión efectiva de la testosterona, el tumor es capaz de continuar su crecimiento. Enzalutamida es un antiandróneno puro de segunda generación de administración oral que actúa a diferentes niveles en la cascada de activación de señales del receptor androgénico y que ha demostrado ser efectivo en esta etapa de la enfermedad. En los ensayos clínicos realizados ha demostrado beneficios en supervivencia global en pacientes diagnosticados de cáncer de próstata metástásico resistente a castración. Estudios recientes también han demostrado beneficio en supervivencia libre de progresión en pacientes con cáncer de próstata resistente a castración no metástasico. Enzalutamida presenta un excelente perfil de toxicidad debiendo evitar su administración en pacientes con antecedentes de crisis convulsivas, especialmente si están en tratamiento con medicación anticonvulsivante Enzalutamida se metaboliza rápidamente en el hígado sobre todo a través del CYP2C8 y en menor medida del CYP3A4/5 por lo que su metabolismo puede verse alterado cuando se administran de forma concomitante fármacos inductores o inhibidores de estas isoenzimas del citocromo. Además, enzalutamida puede requerir el ajuste de dosis de otros fármacos ya que se comporta como un inductor potente del CYP3A4 y un inductor moderado del CYP2C9 y el CYP2C19. Aunque el tratamiento con enzalutamida ha alterado significativamente la historia natural de la enfermedad, en la mayoría de los casos esta progresará mediante el desarrollo de mecanismos de resistencia entre los que cabe destacar las mutaciones, sobreexpresión, amplificación y variantes del receptor androgénico así como la producción intracrina de andrógenos. Enzalutamida es un tratamiento a considerar como primera línea en pacientes con cáncer de próstata resistente a castración

RESUMO

Urothelial bladder cancer is a very prevalent disease. At the time of diagnosis 70-80% of the cases present as non muscle invasive tumors. These tumors present a high recurrence and progression rates despite intravesical treatment with Bacille Calmette-Guerin and mitomycin C. Moreover, bladder conditions such as its wall impermeability and the fact that intravesical drugs are constantly being diluted by urine and eliminated do not favor the efficacy of intravesical treatment. This review analyzes new intravesical drugs such as gemcitabine or taxanes with promising results as alternative to the usual treatments or after their failure. In the same way, we detail those application vehicles designed to increase the exposition of the drug to the bladder wall and its penetration into it. We emphasize drug releasing systems, albumin nanoparticles, liposomes, magnetic nanocarriers, polymers, thermosensible hydrogels and mucoadhesives such as chitosan.

RESUMO

El cáncer vesical urotelial es una enfermedad muy prevalente. Al diagnóstico el 70-80% de los casos se presentan como tumores no músculo infiltrantes. Estos tumores presentan una elevada tasa de recurrencia y progresión a pesar del tratamiento intravesical con Bacilo de Calmette Guerin y con mitomicina C. Además las condiciones de la vejiga, como la impermeabilidad de su pared y el hecho de que los fármacos intravesicales estén siendo constantemente diluidos por la orina y eliminados, no favorecen la eficacia del tratamiento intravesical.En esta revisión se analizan aquellos nuevos fármacos intravesicales como la gemcitabina o los taxanos con resultados prometedores como alternativa o tras fracaso de los tratamientos habituales. Igualmente se detallan aquellos vehículos de aplicación diseñados para aumentar la exposición del fármaco a la pared vesical y su penetración en la misma. Destacan los sistemas de liberacion de fármacos, las nanopartículas de albúmina, los liposomas, los nanotransportadores magnéticos, los polímeros, las hidrogeles termosensibles y los mucoadhesivos como el chitosan

RESUMO

En este artículo se realizó una revisión sobre las diferentes pruebas que se utilizan para el estudio y seguimiento de las estenosis uretrales. Debido a que no hay un consenso sobre como evaluar la patología uretral, se revisó cada una de las siguientes pruebas diagnósticas: los cuestionarios, la flujometría, ecografía, uretroscopia, uretrografía, TAC y RMN; resumiendo sus beneficios y limitaciones en el diagnóstico y seguimiento de la patología uretral. La uretrografía y la uretroscopia son las pruebas más utilizadas, ya que son las que nos aportan mayor información en la evaluación de la estenosis y en la planificación de la cirugía. Los cuestionarios y la flujometría tienen un papel fundamental a la hora del seguimiento de estos pacientes. La ecografía tiene una alta sensibilidad y especificidad para la evaluación de la espongiofibrosis; sin embargo, no se realiza de forma rutinaria. El TAC/RMN se sugiere como evaluación cuando se asocian a traumatismos con fracturas pélvicas


This article presents a review of the different tests used for the evaluation and follow-up of urethral strictures. Because there is no consensus on how to assess urethral pathology, we reviewed each of the next follow-up tests: questionnaires, uroflowmetry, ultrasound, urethroscopy, urethrogram, CT scan and MRI, outlining their benefits and limitations in the diagnosis and follow-up of urethral stricture. Urethrogram and urethroscopy are the most commonly used tests, as they are those that give us more information on the evaluation of stenosis and for surgery planning. Questionnaires and uroflowmetry play a key role in the follow-up of these patients. Ultrasonography has high sensitivity and specificity for evaluating the spongiofibrosis, however it is not done routinely. The CT/MRI is recommended in the evaluation of pelvic trauma associated with fractures

RESUMO

OBJECTIVES: Testosterone deficit syndrome (TDS)is a clinical and biochemical entity characterized by low testosterone levels and androgenic deprivation clinic, which can cause a decrease in the quality of life. However, today there are doubts about its diagnosis and therapeutic management. METHODS: Bibliographic review using the MedLine database and detailed presentation of one clinical case. RESULTS: Testosterone deficit syndrome is associated with metabolic syndrome (visceral obesity, arterial hypertension, diabetes mellitus and dyslipemia). Currently, the performance of TDS screening in all males over the age of 45 years is under discussion. We propose a diagnostic-therapeutic algorithm for the management of TDS and erectile dysfunction. CONCLUSIONS: The treatment of erectile dysfunction associated with late start hypogonadism follows the same steps tha other generic cases of erectile dysfunction.

RESUMO

OBJETIVO: El síndrome de deficiencia de testosterona (SDT) es una entidad clínica y bioquímica caracterizada por niveles bajos de testosterona y clínica de deprivación androgénica, que puede provocar una disminución de la calidad de vida, sin embargo hoy en día existen dudas sobre su diagnóstico y manejo terapéutico. MÉTODOS: Revisión bibliográfica mediante la base de datos de Pub Med y exposición detallada de un caso clínico. RESULTADOS: El síndrome de deficit de testosterona se asocia con el síndrome metabólico (obesidad visceral, hipertensión arterial, diabetes mellitus y dislipemia): en la actualidad se discute si hacer cribado del SDT en todos los varones mayores de 45 años. Proponemos un algoritmo diagnóstico-terapéutico para el manejo del SDT y la disfunción eréctil. CONCLUSIONES: El tratamiento de la disfunción eréctil asociada al hipogonadismo de origen tardío sigue los mismos pasos que en otros casos genéricos de disfunción eréctil (AU)

RESUMO

OBJECTIVE: To report a new case of bladder schistosomiasis. METHODS: A 21-year-old patient came to our consultation with gross hematuria several weeks before, existing reddish lesions in the cystoscopy that suggested the existence of an atypical bladder tumor. RESULTS: After intense blood and urine test, ultrasonography and intravenous urography, transurethral resection of bladder was performed and the diagnosis on histological examination was bladder schistosomiasis. CONCLUSIONS: Given the high prevalence of schistosomiasis in the sub-Saharan countries and later clinical epidemiologic implications, the appearance of macro or microscopic hematuria in black race immigrants, or even any urinary symptoms, it is necessary a complete evaluation, at least with a parasitological analysis (being the bilharziasis the most probably reason). The patients who have suffered severe urinary schistosomiasis must complete long-term follow-up to prevent bladder carcinoma.

RESUMO

OBJETIVO: Aportación de un nuevo caso de esquistosomiasis vesical.MÉTODOS: Paciente de 21 años que acude a nuestra consulta con hematuria de varias semanas de evolución, observando en la cistoscopia la existencia de lesiones rojizas sobreelevadas que sugieren la existencia de un tumor vesical atípico.RESULTADOS: Tras ser sometido a un análisis de sangre y orina rigurosos, pruebas de imagen y, posteriormente, resección transuretral vesical el paciente es diagnosticado en el estudio anatomopatológico de esquistosomiasis vesical. CONCLUSIONES: Dada la elevada prevalencia de la esquistosomiasis en los países subsaharianos y sus posteriores implicaciones clínicoepidemiológicas, la aparición de una hematuria macro o microscópica en inmigrantes de raza negra, o incluso la aparición de cualquier sintomatología urológica, necesita una evaluación completa, al menos con un estudio parasitológico que considere la bilharziasis como la causa más probable.Los pacientes que han padecido esquistosomiasis urinaria severa deben someterse a un seguimiento a largo plazo para prevenir y detectar el desarrollo de carcinoma vesical(AU)

RESUMO

Radical nephrectomy is the only curative treatment for renal cell cancer. Standard treatment includes ipsilateral adrenalectomy and lymph node dissection. In recent years, development of nephron-sparing surgery and early detection of small renal tumors has led to question this approach. The role of lymphadenectomy and adrenalectomy in surgical treatment of renal cancer is reviewed.

RESUMO

El único tratamiento con intención curativa del cáncer renal es la cirugía. La nefrectomía radical inicialmente incluía la adrenalectomía ipsilateral y la linfadenectomía regional. En los últimos años el desarrollo de la cirugía conservadora renal así como el diagnostico en un estadio cada vez más precoz de los tumores renales han llevado a plantearse la conveniencia de realizar tanto la linfadenectomía como la adrenalectomía. En esta revisión se recogen las indicaciones tanto de la linfadenectomía como de la suprarrenalectomía en el tratamiento quirúrgico del cáncer renal obtenidas tras una revisión de la literatura (AU)

RESUMO

Open radical cystectomy with lymph node dissection remains the gold standard treatment for recurrent, high-grade, non-muscle-invasive and for muscle-invasive bladder cancer. The excellent perioperative and long-term results provided by laparoscopic surgery and the advances in instrumentation design have naturally paved the way for development of laparoscopic radical cystectomy (LRC). In this review, surgical and long-term oncological outcomes of LRC are analysed. The advantages of this technique compared with open surgery are described. The differences between pure laparoscopic technique or laparoscopic cystectomy and extracorporeal urinary diversion have also been analysed.

RESUMO

OBJECTIVES: The surgical procedures for the insertion of tension free vaginal tapes in the treatment of female stress urinary incontinence (SUI) are simple and can be done as outpatient operations. The aim of this study was to perform a budget study comparing TVT in an outpatient basis with transobturator tape (TOT) with hospital admission. METHODS: Retrospective analysis of the medical records of 23 patients undergoing surgery for SUI between October 2004 and October 2005. 13 patients were treated by TVT in an outpatient basis (group 1, Department of Urology), 10 patients were treated by TOT with hospital admission (Group 2, Department of Gynaecology). Cost analysis was carried out by the construction of a Marcov model, incorporating the time sequence of the treatment, including adverse events and results. Variables considered for the analysis: number of visits, preoperative tests, operative time, tape cost, hospital stay, unpredicted visits in the first postoperative month at the outpatient clinics or emergency room, and hospital readmissions. Statistical analysis was performed with the G-Stat software. Student's t test was used to compare quantitative variables. RESULTS: 11/13 patients (84.6%) in group 1 completed the day-surgery protocol. Mean surgical time was 61.7 min. (SD 16.2; 35-100) and 61.6 min. (SD 8.3; 50-73) for groups I and 2 respectively. Two cases in group 1 had perioperative complications (15.4%); no patient in group 2 had perioperative complications. Mean hospital stay was 1.3 days for group 1 (SD 0.85; 1-4) and 2.9 days for group 2 (SD 0.31; 2-3). Three patients in group 1 (23%) and 2 in group 2 (20%) presented postoperative complications. Mean cost per process was 4740 EUR for group 1 and 7099 EUR for group 2. CONCLUSIONS: SUI correction by tension free tapes as day surgery is a valid option which saves a substantial amount of resources.

RESUMO

Objetivo: Las técnicas de inserción de mallas periuretrales libres de tensión para el tratamiento de la incontinencia urinaria de esfuerzo (IUE) son sencillas y permiten la realización del procedimiento en régimen cirugía mayor ambulatoria (CMA). El objetivo del trabajo es realizar un estudio de impacto presupuestario comparando la TVT en régimen de CMA con la TVT-O en régimen de cirugía con ingreso. Métodos: Análisis retrospectivo de 23 pacientes intervenidas por IUE entre octubre del 2004 y octubre del 2005. Trece (13) pacientes fueron tratadas en el servicio de urología (TVT - CMA) (Grupo 1) y 10 en el servicio de ginecología (TVT-O con ingreso)(Grupo 2). Se llevó a cabo un análisis de costes mediante la construcción de un modelo de Marcov, que incorpora la secuencia temporal y lógica del tratamiento, incluyendo los acontecimientos adversos y los resultados. Las variables consideradas para el cálculo de coste global incluyeron el numero de visitas y pruebas complementarias preoperatorios; los tiempos de quirófano, el coste del implante, las estancias, y las visitas imprevistas en consultas, urgencias y/o reingresos durante el primer mes posterior a la cirugía. El análisis estadístico se realizó con el programa G-Stat. Las comparaciones entre variables cuantitativas se realizaron mediante la prueba de la t de student. Resultados: Once de las 13 pacientes (84.6%) del grupo 1 completaron satisfactoriamente el protocolo de CMA. El tiempo medio de quirófano fue de 61.7 minutos (DE 16.2; Rango 35-100) y 61.6 minutos (DE 8.3; Rango 50-73) (p = 0.97) para los grupos 1 y 2, respectivamente. En el grupo 1 aparecieron complicaciones perioperatorias en 2 casos (15,4%); ninguna paciente del grupo 2 presentó complicaciones. La estancia media en el grupo 1 fue de 1.3 días (DE 0.85; rango 1-4) y en el grupo 2 2.9 días (DE 0.31; rango 2-3) . 3 pacientes presentaron complicaciones postoperatorias en el grupo 1 (23%) y 2 en grupo 2 (20%). El coste medio por proceso fue de 4740 euros para el grupo 1 y 7099 en el grupo 2. Conclusiones: La corrección de la IUE mediante mallas libres de tensión en régimen de CMA es una opción viable que supone un ahorro substancial de recursos (AU)


Objectives: The surgical procedures for the insertion of tension free vaginal tapes in the treatment of female stress urinary incontinence (SUI) are simple and can be done as outpatient operations. The aim of this study was to perform a budget study comparing TVT in an outpatient basis with transobturator tape (TOT) with hospital admission. Methods: Retrospective analysis of the medical records of 23 patients undergoing surgery for SUI between October 2004 and October 2005. 13 patients were treated by TVT in an outpatient basis (group 1, Department of Urology), 10 patients were treated by TOT with hospital admission (Group 2, Department of Gynaecology).

RESUMO

OBJETIVO: En el escroto se han descrito varios tumores tanto derivados de la piel como de los tejidos subyacentes, nevus, quistes epidermoides, quistes dermoides, carcinomas epidermoides, lipomas, leiomiomas, angioqueratomas, linfangiomas, tumores de células granulares, tumores malignos de vaina nerviosa periférica y algunos pseudotumores como fibromatosis o calcinosis nodular. Se describe por primera vez la presencia de un tumor derivado de las glándulas sudoríparas que tiene además la peculiaridad de su gran tamaño. MÉTODO Y RESULTADOS: Paciente, varón de 76 años que consultó por tumoración dolorosa en hemiescroto izquierdo de larga evolución, que presentaba un crecimiento lento y progresivo. Tras la realización de una ecografía de aparato genitourinario que confirmó la presencia de una masa sólida paratesticular izquierda de 4,2 cm de diámetro, se realizó exéresis de dicha masa bajo anestesia local. CONCLUSIONES: El Siringoma Condroide es un tumor derivado de las células sudoríparas, localizado habitualmente en cabeza y cuello, que tiene un pronóstico excelente y únicamente se han descrito recidivas coincidiendo con extirpaciones incompletas del tumor (AU)

RESUMO

OBJETIVOS: Analizar los resultados obtenidos en los 2 primeros años de implantación de una vía clínica para la resección transuretral (RTU) de neoformaciones vesicales diseñada en el Hospital Universitario La Paz. MÉTODOS: Hemos diseñado para la resección transuretral de vejiga una vía clínica de 4 estancias hospitalarias (5 días), y que incluye la siguiente documentación: matriz-verificación, órdenes de tratamiento, verificación de variaciones, hoja de información iconográfica para el paciente y la encuesta de satisfacción del paciente. La información para la evaluación de resultados se ha obtenido de la documentación de la vía y de los datos de actividad del Servicio de Urología. Para valorar los resultados en la eficiencia en el consumo de recursos, se ha realizado una comparación entre la estancia media de los pacientes en vía clínica y un grupo control compuesto por una muestra aleatoria de 50 pacientes sometidos a RTU vesical durante 1997 (AU)
