Trial Outcomes & Findings for Post Market Study Of Single Incision Sling Versus Transobturator Sling for Stress Urinary Incontinence (NCT NCT01784588)

NCT ID: NCT01784588

Last Updated: 2021-02-10

Results Overview

An assessment of improvement in stress urinary incontinence at 36 months, by a composite of objective (negative cough stress test with protocol required bladder fill procedure) and subjective measures (subject self reported improvement in their condition, through the Patient Global Impression of Improvement (PGI-I)). The PGI-I scale rates the patient's improvement or worsening of SUI symptoms relative to baseline. The scale is as follows: 1 - Very much better; 2 - Much better; 3 - A little better; 4 - No change' 5 - A little worse; 6 - Much worse; 7 - Very much worse, with the unit of measure being scores on a scale (lower scores indicate a more positive impression of change). Subjects met the definition of treatment success at 36 months if they had an answer of "No" to the item "Direct observation of urine loss with cough provocation" and an Improvement per the PGI-I (a response of "A little better", "Much better", or "Very much better").
