title: [The long-term outcome of Studer neobladder and associated complications].
abstract: 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.
