Purpose: The primary aim of our study was to evaluate mesh movement on ultrasonography and to compare the relationship between suburethral mesh angle and incontinence recurrence. Methods: This study was carried out at the University of Selcuk, Konya, Turkey, Beyhekim State Hospital, Konya, Turkey and the Mus State Hospital between September 2012 and January 2015. In total, the results from 109 patients were evaluated in the statistical analysis. The suburethral mesh angle (SMA) is the angle between the two arms of the trans-obturator tape (TOT) mesh under the urethra. This angle was measured at 10 days, 6 months and 1 year after surgery. Potential risk factors for incontinence recurrence and SMA were compared in logistic regression models. The best cut-off value for SMA was calculated to predict incontinence recurrence. Results: The mean resting SMA did not change with time during follow-up (p = 0.373). However, when comparing coughing SMA values, the first day measurement was significantly different from the other measurements. Another comparison was performed according to the cSMA value at each visit. The difference was significant from the first day. Lung disease and the change in the SMA (cSMA) on day 10 were significant predictors of treatment failure. The cSMA on day 10 to predict first-year treatment failure was 10°, with 61% sensitivity and 96% specificity. Conclusions: Measurement of the SMA can be used as a prognostic factor in TOT surgery. Further research is required to determine the importance of SMA as a prognostic factor.
