Repeat retropubic suburethral sling procedure is effective for recurrent female stress urinary incontinence

Objective The aim of the present study was to investigate the effectiveness of repeat retropubic suburethral sling for recurrent stress urinary incontinence (SUI) in women. Methods A retrospective review was performed of 35 women with SUI who underwent repeat retropubic suburethral sling procedures between May 1994 and November 2014. Treatment outcome was assessed directly or by telephone interview. Sling position and urethral incompetence during straining and coughing after the procedure were evaluated. Results The overall continence rate after repeat suburethral sling procedures was 60% (21/35). Among the 35 women, 19 underwent a simple retropubic suburethra sling procedure and 16 underwent combined suburethral sling and other pelvic floor surgery; the success rate for these 2 groups was 84.2% (16/19) and 31.3% (5/16; P = .001), respectively. The success rate was 60% in patients with normal detrusor function (n = 18/30) and in those with detrusor underactivity (n = 3/5; P = 1.0). For patients with intrinsic sphincter deficiency and bladder base hypermobility, the success rate was 63.6% (n = 14/22) and 53.8% (n = 7/13), respectively (P = .36). Among the 25 patients with transrectal ultrasound follow-up data, the success rate following placement of the second sling at the bladder neck, proximal urethra, middle urethra, and distal urethra was 50% (2/4), 87.5% (7/8), 36.4% (4/11), and 0% (0/2), respectively (P = .122). Conclusion Repeat suburethral sling procedures for recurrent SUI are safe and effective. The position of the second sling at the proximal urethra resulted in a relatively higher continence rate relative to other sites.
