Objective:
The current study investigates the effect of bladder neck (BN) preservation on postoperative continence and positive surgical margins (+SMs).
Patients And 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.
Conclusion:
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.
