Tension-free vaginal tape sling for recurrent stress incontinence after transobturator tape sling failure.

The transobturator tape (TOT) sling is a new minimally invasive technique to treat stress urinary incontinence (SUI). Short-term follow-up studies show high success rates; however, as with any surgical treatment of SUI, failures are known to occur. The treatment of recurrent or persistent stress urinary incontinence after a TOT sling is therefore a new dilemma as well. In this paper, we describe the successful use of a retropubic tension-free vaginal tape (TVT) sling in five patients after failed TOT sling. We present case series of five patients who had TOT slings placed for stress incontinence that failed and subsequently had TVT slings placed for persistent SUI. The TVT slings were placed under local/regional anesthesia without removal of the TOT sling. Retrospective chart review of office and hospital charts was completed, and both objective and subjective data were collected. Five patients had TVT slings placed 6-30 weeks after early failure of TOT slings that were placed for stress urinary incontinence. Postoperatively, all patients with urodynamic testing showed evidence of intrinsic sphincter deficiency; however, all maintained urethral mobility of 30 degrees . All five patients had successful treatment of their incontinence with the retropubic tension-free sling procedure with a mean follow-up of 17 months. Recurrent or persistent stress urinary incontinence after TOT sling may be treated with TVT sling without removal of the TOT sling. Further studies with larger numbers and longer-term follow-up is warranted.
