title: Effect of bladder neck preservation during endoscopic extraperitoneal radical prostatectomy on urinary continence.
abstract: OBJECTIVE
  The current study investigates the effect of bladder neck (BN) preservation on postoperative continence and positive surgical margins (+SMs).
  
  
  METHODS
  150 patients (group 1) who underwent BN-sparing endoscopic extraperitoneal radical prostatectomy (EERPE) and 90 patients treated with EERPE and BN resection (group 2) were retrospectively evaluated.
  
  
  RESULTS
  Both groups were similar for age, prostate-specific antigen and prostate size. There was no significant difference in operative time, mean blood loss or transfusion rate. Mean catheterization time was similar. The overall +SM rates were very similar at 10.7% for group 1 and 10.0% for group 2 (group 1, pT2 = 5.1% and pT3 = 30.3%; group 2, pT2 = 2.9% and pT3 = 33.3%). One of 16 patients in group 1 and 1 of 9 in group 2 had a +SM at BN. Statistically significant differences in continence were observed 24 h after catheter removal and 3 months postoperatively between both groups.
  
  
  CONCLUSIONS
  BN preservation proved to have an impact on postoperative early continence of patients undergoing EERPE. Continence of patients who underwent BN preservation was improved after catheter removal and at the 3-month follow-up in comparison to those without BN preservation, but +SMs were not affected by the BN-sparing surgery.
