Impact of Posterior Urethral Plate Repair on Continence Following Robot-Assisted Laparoscopic Radical Prostatectomy

PURPOSE: The objective of this study is to evaluate the continence rate following reconstruction of the posterior urethral plate in robot-assisted laparoscopic radical prostatectomy (RLRP). MATERIALS AND METHODS: A retrospective analysis of 50 men with clinically localized prostate cancer who underwent RLRP was carried out. Twenty-five patients underwent RLRP using the reconstruction of the posterior aspect of the rhabdosphincter (Rocco repair). Results of 25 consecutive patients who underwent RLRP prior to the implementation of the Rocco repair were used as the control. Continence was assessed at 7, 30, 90, and 180 days following foley catheter removal using the EPIC questionnaire as well as a follow-up interview with the surgeon. RESULTS: There was no statistically significant difference between the two groups in any of the patient demographics. At 7 days, the Rocco experimental group had a continence rate of 19% vs. 38.1% in the non-Rocco control group (p = 0.306). At 30 days, the continence rate in the Rocco group was 76.2% vs. 71.4% in the non-Rocco group (p = 1). At 90 days, the values were 88% vs. 80% (p = 0.718), respectively. At 180 days, the pad-free rate was 96% in both groups. CONCLUSION: Rocco repair offers no significant advantage in the time to recovery of continence following RLRP when continence is defined as the use of zero pads per day. On the other hand, Rocco repair was associated with increased incidence of urinary retention requiring prolonged foley catheter placement.
