SCOTTSDALE, ARIZ. -- The latest study of tension-free vaginal tape to treat urinary incontinence found that 29 of 34 patients were cured at the end of an 11-month follow-up.
Nevertheless, there have been no published randomized studies of the procedure so far, and its long-term results are unknown, Dr. Paul M. Magtibay said at a urogynecology conference sponsored by the Mayo Clinic Scottsdale.
Long-term cure rates for the standard treatment for genuine stress urinary incontinence--Burch retropubic urethropexy--hover around 85%.
Since February of last year Dr. Magtibay treated 34 patients with genuine stress urinary incontinence with tension-free vaginal tape (TVT). Three had intrinsic sphincter deficiency, and all achieved urinary continence.
Less success was seen among eight patients with occult stress urinary incontinence: only six (75%) were dry after surgery, said Dr. Magtibay of the clinic.
During the same period he performed open Burch urethropexies on five patients with failed sacral colpopexies, a Capio sling on patients with recurrent incontinence, and laparoscopic Burch urethropexies on four patients to provide training for surgical residents.
The 85% cure rate with TVT in his small, nonrandomized study compares well with an 87% objective cure rate reported in a review last year of 14 articles and 14 abstracts on TVT. The review included a total of 1,762 patients, with objective results on 666 patients. Patients were followed for a mean of 18 months.
