Ileal orthotopic bladder substitute combined with an afferent tubular segment: long-term upper urinary tract changes and voiding pattern.
OBJECTIVE: Assessment of the long-term morbidity of the upper urinary tract and of the voiding pattern in men with an ileal orthotopic bladder substitute with an afferent tubular segment. MATERIALS AND METHODS: Men surviving more than 5 years after radical cystectomy and orthotopic bladder substitution were evaluated. The urinary tract was regularly assessed with ultrasound and IVU while functional reservoir capacity and continence status were prospectively assessed by voiding volume diaries and a standardized questionnaire. RESULTS: After 5 years 129, after 10 years 45 and after 15 years 8 patients were evaluable. Median age at surgery was 63 years (range 36-80) and median follow-up was 73 months (range 60-201). Of the 254 renal units assessed between April 1985 and September 1998, 199 (78%) had some degree of dilatation in the 20-minute IVU film but rarely at 60 minutes. In 246 (97%) the parenchyma size was normal. Ureteral obstruction presented in 9 (3.5%) units, 4 of which were complete (3 had obstruction preoperatively and 1 postoperatively). Mean creatinine levels remained unchanged from the preoperative values. Functional reservoir capacity averaged 462 ml after 1 year, remained stable and then decreased slightly after 5 years. The daytime continence rate was 94% and 91% after 5 and 10 years, while the nighttime rate was 72% and 60% respectively. Patient age at the time of surgery was an important determinant for reservoir capacity and continence status. CONCLUSIONS: These data suggest that an orthotopic bladder substitution combined with an afferent tubular segment offers a sufficient protection of the upper tract with a low complication rate and has good long-term voiding and continence results. Meticulous lifelong follow-up is an important factor for satisfactory functional long-term outcome.[1]References
