Transobturator tape surgery experience: Urodynamic evaluation of 220 patients in a single tertiary center in Turkey

Abstract

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 increased morbidity. This study was aimed to investigate the intra and postoperative results and complication rates of the TOT procedures used for SUI treatments in a tertiary center located in central Turkey. Methods. A total of 220 patients undergoing TOT procedures for SUI were prospectively evaluated. The demographic and clinical characteristics, preoperative and postoperative 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 vs. 26.01?3.51 ml, p=0.125), there were significant differences in terms of the first urinary urge (142.61?20.25 vs. 145.64?20.91 ml, p<0.001), maximum bladder capacity (423.70?38.43 vs. 402.32?39.46 ml, p<0.001), the Q angle (45.54?5.33 vs. 43.81?6.15, p=0.001), Qmax (37.65+11.54 vs. 24.38+9.26 mL/s, p<0.001), Qave (19.92+9.64 vs. 14.77+8.71 mL/s, p<0.001), number of urinations during the daytime (7.29?1.35 vs. 6.58?1.29, p<0.001), and number of urinations during the nighttime (1.48?1.01 vs. 0.92?0.83, p<0.001). Conclusion: The TOT procedure improves the quality of life of SUI patients and can reduce morbidity. Nevertheless, additional studies are needed to corroborate our findings and to determine the long-term results.
