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).


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.


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).


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