Efficiency of the installation of suburetral loop by different methods in women with stress urinary incontinence

The aim: to assess the effectiveness of the installation of a suburethral loop with fixation in the obturator membrane in various ways in case of stress urinary incontinence in women. Material and Methods. 191 women aged from 35 to 65 years old were selected with stress urinary incontinence, which were installed with a suburethral loop with fixation in the obturator membrane in various ways: using an in-out trocar method (group A, n=65); trocar out-in method (group B, n=67); without trocar method in-out (group C, n=59). Randomization of patients into groups was carried out by random numbers. As the primary outcome of the installation of a suburethral loop with fixation in the obturator membrane, the frequency and severity of stress urinary incontinence recurrence was studied using a cough test and a Valsalva test after 12, 36 and 60 months. The timing of surgery, the structure and frequency of the immediate postoperative complications were evaluated as secondary outcomes. Results. The time of the operation in group Awas 31 (30; 33) minutes, in group В 53 (52; 54) minutes, in group С 29 (28; 30) minutes, respectively, F12=1908; p=0,001. Stress incontinence recurrence within 12 months after surgery developed in 3.1 % in group A, 0% in group В and 5.1 % in group С (p =0,14; pAC=0,57; p =0,061); within 36 months after surgery in 7.6; 0; 10.1%, respectively (p =0,02; pAC=0,628; pBC=0,007); for 60 months after the operation in 24.6; 11.9; 28.8%, respectively (pAB=0,017; p =0,421; pBC=0,018). Conclusion. Despite the longer time to perform surgery and greater technical complexity, the installation of a suburethral loop with fixation in the obturator membrane by the out-in trocar method is accompanied by a lower incidence of early postoperative complications and recurrence of the disease.
