Purpose: Early urinary control is a major goal for patients undergoing robot-assisted radical prostatectomy (RARP). We report our technique of posterior urethral suspension (PUS) performed at the time of urethrovesical anastomosis. Patients and Methods: We prospectively followed men with localized prostate cancer undergoing RARP by a single surgeon from August 2012 to October 2015. Patients before April 2014 underwent only bladder neck preservation (controls), while patients after April 2014 also underwent PUS. Patients were given a modified Expanded Prostate Cancer Index Composite questionnaire, along with questions depicting objective measures of urinary control (type of pad, number of pads, wetness of pad). Time points queried were preoperatively and postoperatively at weeks 1, 2, 4, and 12. Our primary outcome was pad-free survival. Results: Questionnaire response rate was 52% (56/107) for controls and 43% (36/83) for PUS. There were no differences in baseline demographics, preoperative urinary control, intraoperative variables, or postoperative complications between groups. There were few subjective improvements in urinary control for PUS compared with controls. More notable, PUS patients had significantly improved objective measures of urinary control, including less protective incontinence products at 1 and 2 weeks after catheter removal (p < 0.03). They also wore fewer pads and had less leakage on each pad that lasted from week 1 to week 4 after catheter removal (p < 0.01). PUS patients had pad-free rates of 37%, 47%, 54%, and 60% compared with controls 15%, 18%, 24%, and 36%, at weeks 1, 2, 4, and 12 after catheter removal (p = 0.07). Conclusion: PUS may improve objective measures of early urinary control compared with controls. With no increase in operative time and no change in complication rates, further work in a randomized setting would provide additional weight to our findings.
