Functional results of hautmann neobladder with chimney modification and wallace ureteroileal anastomosis: initial experience with 22 patients

OBJECTIVE: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. MATERIALS AND METHODS: Between January 2015 and October 2019, 22 patients (18 men and 4 women) u...

Sumario:OBJECTIVE: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. MATERIALS AND METHODS: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45–74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. RESULTS: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. CONCLUSIONS: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.
