Pubovaginal sling (PVS) procedures are designed to curtail bladder leakage brought about by strenuous events such as child birth. A common purported side effect of PVS is urgency, the feeling of a compelling need to void with little warning. Other overactive bladder (OAB) adverse effects that some claim to develop post-op include further leakage (incontinence), frequency and nocturia (night time leakage). Anecdotal evidence from our clinic however, suggests that such de novo OAB symptoms are rarely induced by PVS, and may in fact be alleviated by said procedure. It is our aim to investigate this relationship in our clinic.

As a prospective member of this study, you will be asked to complete five surveys. The first survey will be administered prior to your pubovaginal sling. This will be used to establish your baseline experience of OAB. Over the course of the next year, you will be asked to complete the four remaining surveys at regularly scheduled check-ups.

Primary Outcome Measures:
  • Change in OAB Symptoms Post Pubovaginal Sling Operation [ Time Frame: Baseline to final follow-up. ]
    Measured through the administration of five overactive bladder questionnaires. Difference from baseline to follow-up evaluated using the Wilcoxon Signed Rank Test.

Enrollment: 132
Study Start Date: October 2010
Study Completion Date: June 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pubovaginal sling procedure
Patients undergoing pubovaginal slings for stress urinary incontinence.
Device: Pubovaginal sling procedure
The procedure involves placing a band of sling material directly under the bladder neck (ie, proximal urethra) or mid-urethra, which acts as a physical support to prevent bladder neck and urethral descent during physical activity. The sling also may augment the resting urethral closure pressure with increases in intra-abdominal pressure.
