Complications and re-operations after tension-free vaginal tape operation in women with stress urinary incontinence.

Abstract

We evaluate intraoperative and short-term postoperative (≤ 3months) complications and long-term re-operations (up to 6years) after tension-free vaginal tape (TVT) operation in women with stress urinary incontinence (SUI). Data from 446 women undergoing TVT operation between 2012 and 2016 at a tertiary referral center was retrospectively collected. Data included patient baseline demographics, information from the TVT operation and the following postoperative period, and scores from patient questionnaires [the International Consultation of Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and Patient Global Impression of Improvement (PGI-I)]. Collected data were investigated for incidence of complications and re-operations, postoperative improvement in patient questionnaires, and association between complications and baseline patient demographics. The only intraoperative complication was bladder perforation (2.0%). Postoperative complications included: infection (0.7%), hematoma (0.9%), bleeding (0.2%), pain (0.9%), erosion of the vaginal mucosa (1.1%), persistent SUI (0.7%), and voiding dysfunction > 24h (10.3%). Re-operations included: operation due to infections (0.4%), incontinence surgery for persistent SUI (0.4%), revision for tape erosion (1.1%), tape mobilization (3.6%), and tape division (0.2%). A significant reduction in urinary incontinence symptoms was observed in the ICIQ-UI SF and PGI-I. The reduction in ICIQ-UI SF did not vary significantly between patients with and without complications. No association between complications and baseline patient demographics was found. This study demonstrated high safety and efficacy of the TVT operation with only minor short-term complications and few long-term re-operations. The ICIQ-UI SF improved significantly postoperatively and was not statistically significantly affected by the occurrence of complications.
