The correction of type 2 stress incontinence with a polytetrafluoroethylene patch sling: 5-year mean followup.
OBJECTIVE
The durability of pubovaginal sling procedure for type 2 stress urinary incontinence was evaluated by a questionnaire survey.


METHODS
From 1989 to 1996, 48 patients with type 2 stress urinary incontinence were treated with a polytetrafluoroethylene patch sling. Tightness of the sling was adjusted by setting the posterior urethrovesical angle at about 90 degrees under ultrasound monitoring. Study inclusion criteria were no urine leakage for at least 24 months confirmed by questionnaire and no recurrent urinary incontinence during followup.


RESULTS
We received answers from 39 patients (81.3%), of whom 1 was excluded from study due to less than 24-month followup (18 months) without urine leakage. Of the 38 patients 32 (84.2%) reported no leakage of urine, 4 (10.5%) were subjectively improved, 2 (5.3%) were the same and none was worse, for an overall cure or improved rate of 94.7%. Followup of the 32 patients maintaining urinary continence averaged 65.9 +/- 29.4 months. Of the patients 6 (15.8%) had slight pelvic pain, 4 (10.5%) always and 10 (26.3%) sometimes had to strain to void, and 14 (36.8%) complained pollakisuria. Urge incontinence coexisted in 5 of 6 patients reporting improved or the same status. Of all patients 31 (81.6%) were satisfied with the decision to undergo the operation.


CONCLUSIONS
Durability and safety of our procedure for stress urinary incontinence were confirmed by the survey questionnaire. Most of the patients complained of no or little difficulty voiding.
