F. Haab et al., Results of the tension-free vaginal tape procedure for the treatment of type II stress urinary incontinence at a minimum followup of 1 year, J UROL, 165(1), 2001, pp. 159-162
Purpose: We evaluated the safety and efficacy of the tension-free vaginal t
ape procedure for treating type II stress urinary incontinence in females.
Materials and Methods: Between April 1998 and April 1999, 62 women 28 to 86
years old (mean age 62.8) were treated consecutively for stress urinary in
continence with the tension-free vaginal tape procedure. Preoperative evalu
ation included history, physical examination and multichannel video urodyna
mics. All patients had type II stress urinary incontinence, none had preope
rative detrusor instability or significant pelvic prolapse and in 16 previo
us surgery for stress incontinence had failed.
Results: All patients were followed at least 12 months after the procedure
(median 16.2). A total of 42 and 20 women received spinal and local anesthe
sia, respectively. We noted 6 bladder perforations, including 5 in patients
with a history of surgery for stress urinary incontinence. Blood loss was
less than 200 cc in all cases. We observed no prolonged postoperative pain,
infection or sling rejection. Post-void residual urine was less than 100 c
c the day after surgery in 59 cases. Only 3 patients self-catheterized a ma
ximum of 4 days. At followup 54 women (87.1%) were cured of stress urinary
incontinence, 6 were improved (9.6%) and 2 had failure (3.3%), while 4 (6.4
%) had new onset detrusor instability without evidence of bladder outlet ob
struction.
Conclusions: The tension-free vaginal tape procedure appears to be a minima
lly invasive, safe and effective treatment for type II stress urinary incon
tinence. A history of surgery for stress incontinence seems to be a risk fa
ctor for bladder perforation.
