Comparison of transobturator tape and mini-sling tissue fixation in female patients who had stress urinary incontinence

Abstract

Background. Urinary incontinence is a significant medico-social problem and its incidence increases up to 70% in the postmenopausal period. Objectives. We aimed to compare the efficacy and safety of transobturator adjustable tape (TOT) and mini sling in female urinary incontinence. Material and Methods. A total of 69 patients were included in the study. Single surgeon applied TOT (n = 56 with ISD) or 13 mini sling (n = 13 with ISD). Patients were considered to have ISD identified by a Valsalva leak point pressure (VLPP) measurement < 60 cm H2O with a volume of 150 mL in the bladder or by a maximum urethral closure pressure (MUCP) measurement < 20 cm H2O with a volume of 200 mL in the bladder. The mean follow-up period was 25 months for TOT group and 24 months for mini sling group (p = 0.72). Results. The cough test was negative in 48 of TOT group (86%) and 11 of mini sling group (84.6%). ICIQ-SF scores for the median value decreased from 14 (11-21) preoperatively to 3 (0-9) postoperatively (p < 0.05) in the TOT group, and 15 (12-23) preoperatively to 4 (0-10) postoperatively (p < 0.05) in the mini sling group. The difference in the decrease of the score between two groups was not statistically significant (p = 0.42). There was not any significant complication to note. The mean hospital stay for TOT group was 2.1 days (1-5), and 1.4 days (1-3) for mini sling group (p = 0.12). Operation time was was significantly lower in mini-sling group than TOT group (11.6 vs. 18.4, p < 0.01). Conclusion. Both TOT and mini-sling procedures are successful and safe procedures in the treatment of female stress urinary incontinence with ISD.
