Investigation of the Necessity of Urodynamic Test in Patients with Urinary Stress Incontinence for TOT Surgery

Stress urinary incontinence is one of the most common diseases which canreduce the quality of life in women. Urodynamic test is a common method of diagnosis of this disease.This study is designed for investigating the necessity of urodynamic test in patients with urinary stressincontinency before transobturator tape (TOT) surgery. Urodynamic test before surgery can affect thequality of life in patients.

This study was a randomized clinical trial. The sample size was 48 patients divided into twogroups of 24 women in January 2018. Women with urinary incontinence complaints were randomlydivided into two groups. For the first group, the urodynamic test was done. Both groups were evaluatedone month and six months after TOT surgery based on the results of the I-QOL questionnaire.

The mean I-QOL score was 83.9 ± 3.3 in questionnaire group and 81.6 ± 4.6 in urodynamicgroup one month after surgery with no statistically significant (P = 0.052) difference. The quality of lifescore after 6 months was 87.2 ± 4 in the questionnaire group and 85.4 ± 3 in the urodynamic groupwith no statistically significant differences with each other (P = 0.084).

In this study, the urodynamic test only had additional information related to lower urinarytract symptoms and it did not have effects on improving the outcome of the surgery. The test onlyimposes economic burden. Therefore, the urodynamic test is not required before surgery in patientswith urinary stress incontinence.
