Purpose
The suburethral sling procedure has been widely used as the first-line treatment for female stress urinary incontinence (SUI). This study retrospectively compared the long-term surgical outcomes and complications between retropubic and transobturator suburethral sling procedures.
Methods
From 2010 to 2022, a total of 533 women with SUI underwent retropubic pubovaginal sling (PVS) or transobturator tape (TOT) procedures using a synthetic polypropylene mesh with or without concomitant anterior colporrhaphy. All patients underwent preoperative videourodynamic studies, Valsalva leak point pressure (VLPP), and voiding efficiency (VE). The success rate, postoperative complications, overactive bladder symptoms, transvaginal urethrolysis, and repeat procedures were compared among different surgical procedures.
Results
Among the patients, PVS was performed in 251 (47.1%) patients and with colporrhaphy in 58 (10.9%), TOT in 174 (32.6%) and with colporrhaphy in 50 (9.4%). The success rate was 87.4% in the PVS group and 75.4% in the TOT group, with or without colporrhaphy (p = 0.001). Urethrolysis was performed in 4.7% of the patients, and repeat suburethral sling procedures were performed in 8.3%. The overall success rate was significantly lower in TOT group, either with high or low VLPP, or with high or low VE. The rate of persistent OAB was significantly higher in TOT group regardless of VLPP or VE, whereas patients with VE < 90% at baseline had a significantly higher rate of postoperative dysuria.
Conclusion
TOT procedures had an inferior long-term success rate than PVS procedures for female SUI. Additionally, no differences in the success rate were observed between patients with different bladder functions, high or low VLPP, and high or low VE.
