Abstract
The purpose of this study is to assess the positive and negative predictive accuracy of the Stress-Cath® (Continental Pharmaceuticals, UK) as compared to single channel cystometry and a standing cough stress test in the diagnosis of genuine stress incontinence. Twenty-eight women were evaluated for incontinence by single-channel cystometry and a standing cough stress test at cystometric capacity. These same 28 women also underwent a modified fluid bridge test, using a device known as Stress-Cath®. This catheter is able to detect urine in the proximal urethra. The data demonstrated that the Stress-Cath® was 81.3% sensitive and 83.3% specific for the diagnosis of genuine stress incontinence as determined by the simplified urodynamic evaluation. The Stress-Cath® had a positive predictive rate of 86.6% and a negative predictive rate of 76.9%. Its false positive rate was 16.7% and false-negative rate was 18.7%. The Stress-Cath® is relatively insensitive in diagnosing genuine stress incontinence.
