[Effects of treatment of female stress incontinence by intravaginal perineal retraining. Prospective study].

31 stress incontinent women (stage 1 and 2 Ingelman-Sundberg) are treated with Kegel perineal reeducation (levator ani contractions are controlled with an intravaginal finger and with an intravaginal pressure biofeed-back). After a mean of 9 weeks treatments, one treatment 30 mm weekly, levator ani and urethral striated contract in a good way and their contractions are stronger. 64% women are continent. Continence prognostic after treatment is function of the age of incontinence before reeducation (75% stage 1 versus 45% stage 2 become continent) and function of the recovery of a minimal strength of peri-urethral striated sphincter.
