Pessary test to predict postoperative urinary incontinence in women undergoing hysterectomy for prolapse.
OBJECTIVE
We sought to demonstrate that a positive pessary test could predict postsurgical stress urinary incontinence in women with severe pelvic organ prolapse and that performing tension-free vaginal taping (TVT) could effectively prevent its occurrence.


METHODS
Among the 79 patients evaluated for severe pelvic organ prolapse without symptoms of stress urinary incontinence, all underwent meticulous urogynecologic evaluations and pessary testing. In group 1, 32 patients had positive pessary tests and underwent vaginal hysterectomy, anterior and posterior colporrhaphy, and TVT. In group 2, 47 patients (17 of whom had positive pessary tests and 30 of whom had negative pessary tests) underwent vaginal hysterectomy and anterior and posterior colporrhaphy alone. A comparison in terms of surgical outcome and clinical manifestations was made between these 2 groups of patients.


RESULTS
After surgery, a small proportion of patients had de novo idiopathic detrusor overactivity (7.6%, n = 6), urinary tract infections (7.6%, n = 6), mild recurrent prolapse (5.1%, n = 4), and urinary retention (3.8%, n = 3). Eleven (64.7%) of 17 patients with positive pessary tests who did not undergo TVT had urine leakage after their hysterectomies in contrast with the 30 patients who had negative pessary test, none of whom developed symptomatic stress urinary incontinence after vaginal hysterectomy. Among the 32 patients with positive pessary tests who had TVT with their hysterectomies, 3 developed urine leakage later; the cure rate was 90.6%.


CONCLUSIONS
Continent patients suffering from severe pelvic organ prolapse but with a positive pessary test are considered to be at high risk of developing postoperative symptomatic stress urinary incontinence. Among the patients in our medium-range study, TVT effectively prevented postsurgical urinary incontinence.
