title: Outcomes and complications of sphincterotomy with bladder neck incision in neurologically healthy male patients with voiding dysfunction.
abstract: OBJECTIVE
  To evaluate the efficacy, complications and outcomes of sphincterotomy with bladder neck incision in patients with voiding dysfunction (VD).
  
  
  METHODS
  We evaluated our prospectively established urologic urodynamic database and identified the records of 30 male patients with VD that underwent  sphincterotomy between Octuber 1993 and December 2008. The IPSS and urodynamics were analyzed before and after surgery, we recorded the outcomes and complications.  Numerical data were analyzed with Student`s t and Wilcoxon tests (p < 0.05). ANOVA was used for the follow up.
  
  
  RESULTS
  Thirty patients underwent sphincterotomy with a mean age of 41 years (range 18-63 years). Statistical differences  (p< 0.05) were found for: maximum  flow rate (17.61 ± 7.7 vs 23.5 ± 12.19 ml/s), detrusor pressure (73.53 ± 21.51 vs 47.4 ± 16.24 cmH20), maximum  cystometric capacity (462.74 ± 224.2 vs 382.2 ± 167.48 ml),  functional urethral length (64.3 ± 22.6 vs 42.2 ± 18.4 mm), Maximum urethral pressure (120.1 ± 46.8 vs 59.23± 22.67  cmH20), total  urethral closure area (3315 ± 1269.7 vs  1189 ± 49.23 cmH20*mm) and postvoid residual volume (161.3 ± 177.9 vs 57 ± 100.8 ml). The IPSS improved and was stable at 60  months (p < 0.02).  No significant association  was found to develop incontinence after the procedure.
  
  
  CONCLUSIONS
  Sphincterotomy for male patients with dysfunctional voiding improves voiding dynamics with a low rate of complications and minimum risk of incontinency.
