Objective: To investigate the long-term outcome and related complications in a group of patients underwent Studer neobladder surgery.
Methods: From may 2005 to Jan 2008, 25 patients with invasive bladder tumor underwent Studer procedure. Among of them, 20 patients were followed up from 6 to 44 months. Functional bladder capacity, residual urine, peak flow rate and incontinence in 3, 12, 24, 36 months following neobladder were evaluated. Surgical associated complications, death rate were included as well.
Results: There was no significant difference in functional bladder capacity, peak flow rate after the procedure (P > 0.05), but there was significant difference in residual urine (36 ml vs 80 ml, P < 0.01). Hydronephrosis, renal atrophy, urinary infection and hematuria were major complications encountered in this study.
Conclusions: The procedure is safe, and satisfied urinary function is kept in the neobladder. The long-term outcome will be improved with accumulated experiences.
