Urodynamic Findings in Men Presenting with Incontinence After Open Versus Robotic Radical Prostatectomy

Abstract

Introduction:Urodynamic findings in patients with post-prostatectomy incontinence (PPI) following either an open radial retropubic prostatectomy or a robotic-assisted laparoscopic prostatectomy are not well described. Methods: After IRB approval, we performed a retrospective review of urodynamic findings in patients presenting to our institution with PPI following either an open or robotic prostatectomy from 1985 through 2009. results: One hundred and twenty-six patients were identified for analysis (74 robotic, 52 open). Intrinsic sphincter deficiency was the cause of PPI in the majority of patients in both groups. Detrusor pressure at peak flow was significantly higher, and peak flow rate was significantly lower in patients who had undergone an open procedure. Anastomotic stenosis (AS) was also higher following an open procedure. Detrusor over-and underactivity were similar between the groups. conclusions: Following an open compared to a robotic prostatectomy, patients experienced elevated voiding pressures and decreased peak flows, presumably secondary to the increased incidence of AS observed in those patients.
