Técnica de Burch en el tratamiento quirúrgico de la incontinencia urinaria de esfuerzo femenina. Valoración de los resultados y análisis de las causas de los fracasos / Burch procedure in the surgical treatment of urinary stress incontinence

OBJETIVO: Presentar nuestra experiencia con la técnica de Burch en el tratamiento de la incontinencia urinaria de esfuerzo femenina (IUE), así como analizar las posibles causas de los fracasos. MATERIAL Y MÉTODOS: En un periodo de 10 años (1987-1997), se han intervenido 157 pacientes afectas de IUE mediante esta técnica. Su edad media era de 54,2 años (30-76) y el seguimiento medio fue de 50,24 meses. La técnica se indicó sin tener en cuenta los hallazgos de la exploración física, la severidad, ni los resultados del perfil uretral en el estudio urodinámico. RESULTADOS: A los tres meses de la cirugía, el porcentaje de curación/mejoría fue del 80,7 por ciento. Al año desciende al 76 por ciento. A partir del 2º año se estabilizaron en torno al 70 por ciento y se mantiene a los 5 años. Si tenemos en cuenta la severidad de la incontinencia, si ésta es leve-moderada, el porcentaje de buenos resultados a los 5 años es del 87 por ciento. Si existen alteraciones asociadas del detrusor, baja al 51,8 por ciento, y si el perfil uretral es malo desciende al 42,4 por ciento. CONCLUSIONES: La técnica de Burch es útil en el tratamiento de la IUE, pero con buena selección de los pacientes (AU)

Assessment of results and analysis of failure causes]. / Técnica de Burch en el tratamiento quirúrgico de la incontinencia urinaria de esfuerzo femenina. Valoración de los resultados y análisis de las causas de los fracasos.

OBJECTIVE: To present our experience with the Burch procedure in the treatment of female urinary stress incontinence (USI) and the assessment of the causes of failure with this technique. MATERIAL AND METHODS: From January 1987 to june 1997 this technique was applied to 157 patients with USI. The mean age of these women was 54.2 years (30-76) and the mean follow-up was 50.24 months. Physical examination, urethral profile and the severity of the USI were not considered in the indication of the procedure. RESULTS: After three months, we had total continence or improvement in 80.7%. This rate decreased to 76% after one year. From the second year it was 70%, maintained to fifth year. Considering the severity of incontinence, in patients with mild-moderate grade, we obtained good outcomes after 5 years in 87%. If there was associated detrusor alterations, the rate decreased to 51.8%, and with a bad urethral profile, decreased to 42.4%. CONCLUSIONS: The Burch procedure is useful in the treatment of USI but requires a good selection of the patients.

[Renal adenocarcinoma with vena cava invasion: current status of its diagnosis and treatment using total segmentary cavectomy]. / Adenocarcinoma renal con invasión de vena cava: estado actual de su diagnóstico y tratamiento mediante cavectomía total segmentaria.

OBJECTIVES: Renal adenocarcinoma is characterized by marked venotropism; 20-49% show extension into the main renal vein and 4-19% into the vena cava. The present study analyzes the different diagnostic methods to evaluate the vascular involvement by renal carcinoma and presents the results achieved by total segmental cavectomy with ligation of the left renal vein and without vena caval reanastomosis. METHODS: Three patients (two males, one female) underwent total segmental cavectomy with ligation of the left renal vein in our Service over the last 10 years. A bilateral subcostal approach with access to the large vessels was utilized in all three cases. The superior and inferior renal vena cava were exposed and the hepatic veins were ligated at the level of the intrahepatic segment. Incision of the vena cava was performed, the thrombus was removed and the renal vessels were ligated. The proximal and distal segments of the vena cava were ligated after cavectomy. In the third patient, intrahepatic extension of the thrombus required the use of a temporary filter for the proximal segment of the vena cava. RESULTS: The early postoperative course was satisfactory; adequate renal function was maintained and no problems with venous return were observed. Of the diagnostic methods analyzed, MRI was found to be the most useful. A relationship was found between survival and the pathological stage and the presence or absence of lymph node metastasis. CONCLUSIONS: Total segmental cavectomy without reanastomosis and with ligation of the left renal vein appears to be a feasible technique which achieves good results. MRI is the diagnostic method of choice in the evaluation of vascular tumor extension.

[Ureterohydronephrosis secondary to a cyst of retroperitoneal mesentery]. / Ureterohidronefrosis secundaria a quiste de mesenterio retroperitoneal.

Retroperitoneal primary cysts are rare clinical entities. A contribution is made of one case presenting this condition with repercussion on the excretory route. Ultrasound and computerized axial tomography studies suggest the diagnosis but this is confirmed through laparotomy. Choice treatment is enucleation, typically easy because of the minimal adherence to surrounding structures. Recurrence is rare and malignancy practically non-existent.
