Comparative analysis of the efficacy and safety of suburethral slings TVT-O and TVT-Abbrevo in female incontinence treatment

Introduction. Transobturator approach to the sling placement for female incontinence is linked to some risks: vaginal wall perforation, damage of the adductor muscles of the thigh and obturator nerves, which could lead to the development of chronic pelvic pain syndrome. New surgical device TVT-Abbrevo, shortened version of TVT-O, could minimize the tissue traumatization. Aim of the study was to compare treatment outcomes with regard to urinary continence for two surgical devices - TVT-O and TVT-Abbrevo. Materials and methods. The study included 74 patients with stress urinary incontinence, which were randomized using the block principle. TVT-O was implanted in 36 patients, modified TVT-Abbrevo implantation was done in 38 patients. Results. Groups were similar concerning the preoperative characteristics. Intra- and postoperative complications were few. Cough test was negative in most patients at 1 month after operation and during the extended follow up with an insignificant trend to better results in TVT-Abbrevo group. Significant differences in the pain intensity and analgesics use were also absent. Conclusions. TVT-Abbrevo has the similar efficacy and safety profile as TVT-O operation.
