Efficacy of Synthetic Suburethral Slings in Female Urinary Stress Incontinence with Overactive Bladder

Objectives: The aim of the present study was to investigate the efficacy of synthetic suburethral slings in female stress urinary incontinence (SUI) patients with overactive bladder (OAB). Methods: From May 2002 to April 2005, a total of 295 women with SUI underwent suburethral sling procedure. Of the 295 women, only those who were followed up for at least 12 months were included in the study, yielding 236 patients. The patients were divided into three groups: pure SUI; SUI with OAB dry; and SUI with OAB wet. Telephone questionnaires by were used to evaluate the postoperative improvement of SUI and storage symptoms. Results: There were significant differences in preoperative symptom score, quality of life (QoL) score, and preoperative voided volume among the three groups. There were no significant differences among the three groups in terms of the cure rate for the stress component (group 1, 88.6%; group 2, 86.2%; group 3, 86.7%; P = 0.943). Eighty percent of group 1 patients improved in frequency, but two patients (2.3%) complained of de novo urgency. In group 2, 81.5 and 82.7% improved in frequency and urgency, respectively, but one patient (1.7%) complained of de novo urge incontinence. In group 3, 76.9 and 84.4% improved in frequency and urge incontinence, respectively. Conclusion: Suburethral slings are simple, safe and highly effective in treating SUI with OAB.
