    ABSTRACT: We evaluated the long-term efficacy of the male bulbourethral sling procedure in the treatment of post-radical prostatectomy urinary incontinence. Between October 1994 and June 2000, 95 patients with post-radical prostatectomy incontinence underwent bulbourethral sling placement with tetrafluoroethylene bolsters at our hospital. Ultimately 71 of these patients responded to our questionnaire and they were classified into 2 groups. Group 1 consisted of 62 patients who had not undergone prior radiation therapy and group 2 consisted of 9 who had undergone radiation therapy before the sling procedure. Patients were asked to respond to questions regarding continence status as well as the validated Incontinence Quality of Life and International Prostate Symptom Score questionnaires. Mean followup from the most recent sling procedure was 4 years (range 0.27 to 6.55). Average patient age at questionnaire response was 74 years. A total of 86 procedures were performed on 71 patients. Of the 71 patients 7 underwent either sling removal or artificial urinary sphincter placement and were excluded from questionnaire analysis. Including retightening procedures 68% of the patients (72% of group 1, 43% of group 2) required 2 or less pads daily. Of the patients 36% (42% of group 1 and 14% of group 2) required 0 pads. The male bulbourethral sling procedure remains an effective treatment for post-prostatectomy incontinence at 4-year followup.

    ABSTRACT: We describe the successful repair of a 6 cm. ureteral stricture involving the right ureteropelvic junction and proximal ureter using appendix as a ureteral substitute. A 37-year-old man involved in a motorcycle accident presented with a retroperitoneal urinoma and a 6 cm. proximal ureteral stricture. At flank exploration we were unable to perform successfully primary pyeloureterostomy through renal descensus with ureteral mobilization. The appendix was selected to bridge the ureteral defect. The right colon and cecum were mobilized to the area of the diseased ureter and the appendix was transected across the base of the cecum. Ureteral scar tissue was resected and the appendix was interposed in an isoperistaltic orientation from renal pelvis to proximal ureter. Convalescence was unremarkable. Retrograde pyelography and flexible ureteroscopy 2 months postoperatively demonstrated a patent anastomosis and viable appendix. The ureteral stent was removed at that time. Excretory urography 3 months postoperatively revealed prompt enhancement of the 2 kidneys and visualization of the 2 ureters. Mercaptoacetyltriglycine-3 renal scan 5 months postoperatively confirmed no scintigraphic evidence of obstruction. The patient was asymptomatic 6 months postoperatively and renal function tests were normal. The appendix can be considered for proximal ureteral defects extending to the right renal pelvis.
