Abstract
Background and aims: Stress urinary incontinence is one of the most common diseases which can reduce 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 stress incontinency before transobturator tape (TOT) surgery. Urodynamic test before surgery can affect the quality of life in patients. Methods: This study was a randomized clinical trial. The sample size was 48 patients divided into two groups of 24 women in January 2018. Women with urinary incontinence complaints were randomly divided into two groups. For the first group, the urodynamic test was done. Both groups were evaluated one month and six months after TOT surgery based on the results of the I-QOL questionnaire. Results: The mean I-QOL score was 83.9±3.3 in questionnaire group and 81.6±4.6 in urodynamic group one month after surgery with no statistically significant (P=0.052) difference. The quality of life score after 6 months was 87.2±4 in the questionnaire group and 85.4±3 in the urodynamic group with no statistically significant differences with each other (P=0.084). Conclusion: In this study, the urodynamic test only had additional information related to lower urinary tract symptoms and it did not have effects on improving the outcome of the surgery. The test only imposes economic burden. Therefore, the urodynamic test is not required before surgery in patients with urinary stress incontinence
Highlights
Stress urinary incontinence occurs during any activity that increases intra-abdominal pressure
The prevalence of urinary stress incontinence is about 4% to 35%.1. It affects the quality of life and health of women, causing significant disability, social isolation, psychological stress, and economic hardship.[2]
According to a pilot study, a sample size of 20 subjects in each group was determined for comparing the total score of questionnaires between the first and the sixth month, considering β = 0.2, α = 0.05, Sd=4.51, and μd =2.8 (SD and mean for paired difference)

Urodynamic test before surgery can affect the quality of life in patients. Results: The mean I-QOL score was 83.9 ± 3.3 in questionnaire group and 81.6 ± 4.6 in urodynamic group one month after surgery with no statistically significant (P = 0.052) difference. The quality of life score after 6 months was 87.2 ± 4 in the questionnaire group and 85.4 ± 3 in the urodynamic group with no statistically significant differences with each other (P = 0.084). The urodynamic test is not required before surgery in patients with urinary stress incontinence.
