Background/Aim. Stress urinary incontinence (SUI) is the involuntary leakage of urine after increased intraabdominal pressure, and it causes a significant public health problem by reducing the quality of life, causing sexual dysfunction, and increasing the cost of care due to in-creased morbidity. The aim of the study was to investigate the intra? and postoperative results and complication rates of the transobturator tape (TOT) procedures used for SUI treatments in a tertiary center located in central Turkey. Methods. This prospective study analyzed a total of 220 patients undergoing TOT procedures for SUI. The demo-graphic and clinical characteristics, preoperative and post-operative cystometry values, and operative outcome parameters of the study participants were analyzed. Results. While no significant difference was noted between the preoperative and postoperative periods with respect to residual volume (27.09 ? 8.51 mL vs. 26.01 ? 3.51 mL, p = 0.125), there were significant differences in terms of the first urinary urge (142.61 ? 20.25 mL vs. 145.64 ? 20.91 mL, p < 0.001), maximum bladder capacity (423.70 ? 38.43 mL vs. 402.32 ? 39.46 mL, p < 0.001), the Q-tip angle (45.54 ? 5.330 vs. 43.81 ? 6.150, p = 0.001), the maxi-mum flow rate (37.65 ? 11.54 mL/s vs. 24.38 ? 9.26 mL/s, p < 0.001), average flow rate (19.92 ? 9.64 mL/s vs. 14.77 ? 8.71 mL/s, p < 0.001), the number of urinations in the daytime (7.29 ? 1.35 vs. 6.58 ? 1.29, p < 0.001), and the number of urinations at nighttime (1.48 ? 1.01 vs. 0.92 ? 0.83, p < 0.001). Conclusion. The TOT procedure im-proves the quality of life of SUI patients and can reduce morbidity. Nevertheless, additional studies are needed to corroborate our findings and determine the long-term effects.
