Study of Urethral Mobility in Male Stress Urinary Incontinence Pre- and Post- Placement of Transobturator Sling

This study has been completed.
Information provided by (Responsible Party):
Duke University Identifier:
First received: January 28, 2013
Last updated: November 4, 2016
Last verified: March 2016
The hypothesis is men with stress urinary incontinence, including those following radical retropubic prostatectomy and other prostate surgery, have preoperative urethral mobility as measured by magnetic resonance imaging (MRI) that improves significantly following sling placement. The investigators theorize that the sling helps with primary hypermobility of this pathophysiologic cause of stress urinary incontinence.

Condition Intervention
Male Stress Urinary Incontinence Other: Pre and Post Sling Pelvic MRI

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
