INTRODUCTION AND HYPOTHESIS:

The aim of this study is to investigate the effect of intrinsic sphincter deficiency (ISD) and urethral hypermobility on the outcome of the transobturator tape (TOT).

METHODS:

Sixty-five women were divided into three groups: group I, ISD with hypermobile urethra (n = 18); group II, ISD with fixed urethra (n = 16); and group III, hypermobile urethra without ISD (n = 31). Cure of stress urinary incontinence was defined if the patient had negative cough stress test. Cure and improvement rates were compared at 6, 12, and 24 months.

RESULTS:

The cure and improvement rates of groups I and III were similar at 6, 12, and 24 months (96.1% vs 96.6%, 96.1% vs 96.6%, and 87.5 vs %96.4%, respectively). Group II had the lowest cure and improvement rates (68.7%, 66.7%, and 66.7%, respectively).

CONCLUSION:

A lack of urethral hypermobility may be a risk factor for TOT failure.
