Short-term complications of the trans-obturator foramen procedure for urinary stress incontinence

This paper reports the efficacy and complications of the trans-obturator foramen procedure (TOT). The effect of TOT on co-existing urgency and urge incontinence and voiding difficulty were also noted. It reports on patients (31) undergoing TOT (Obtape) from April 2005 to April 2006, who were sent a questionnaire. The mean age was 53 years, mean parity 2.3, mean duration of incontinence 6.2 years and the mean duration of follow-up was 9 months. All patients had significant stress incontinence. Co-existing urge incontinence was present in 70%; no intraoperative complications. One patient had a urinary tract infection (UTI) and one, catheterisation for 5 days. A total of 16.6% of patients developed sling erosion. There was a 93% response rate to the postal survey, indicating a 31% complete cure of urinary incontinence; 65% a significant improvement and 3.5% failure. Urge incontinence disappeared in 66%, no de-novo urgency and 8% reported slower voiding. Satisfaction was 8.9 on a 1 - 10 Scale. The success rate of the TOT procedure was high, helping both stress and concomitant urge incontinence, but due to an unacceptably high erosion rate, Obtape was discontinued.
