The UI treatment has been by preference surgical, not withstanding, even though they feel uncomfortable because of urinary loss, some women are reluctant to have surgery, which may lead to complications in the post-operative. Others have clinical counter indications for the anesthesia-surgical procedure to take place. The oldest mention of this therapy for the treatment of urinary incontinence occurred in a medical text in the Swedish Work, published in 1861. In this article they did not describe the type of exercises that were used 12. HENRIKSEN observed that the act of starting or interrupting the urinary flux during urination, led to sphincterian strengthening and consequently to diminish urinary loss 13. ARNOLD KEGEL 14, in 1948, was the first one to describe, in a systematic way, an evaluation method and an exercise program for the strengthening of the pelvic floor muscles. He used two different methods to evaluate the tonus of the pelvic musculature, subjectively by digital palpation of the vaginal introit, and objectively through the perineometer. KEGEL 14 emphasized the importance of supervision and encouragement in the treatment of these patients, and recommended that the controls should be weekly. The re-establishment of the tonus and muscular function, could, according to the author, happen after 20 to 60 days from the beginning of the treatment. This author, studying 64 women with stress urinary incontinence, using the perineometer for 20 minutes, three times a day, for a period of one or two weeks, obtained continence in all the cases, with a follow-up of 14 months 14. In another series, he observed an index of cure of 80%, studying 500 patients 15. Other authors refer to similar results 16,17.It was observed that there would not be any failures in these therapeutical modalities when urinary incontinence was due primarily to flaccidity or partial atrophy of the pelvic floor muscles 14. BO et al 18 showed that an adequate supervision might improve the results obtained with perineal exercises. There exists a relation of dependency between perineal exercises and urinary continence, meaning; not being successful is bigger in patients that do not follow adequately the protocol of the exercises. FINCKENHAGEN et al 19 1998, treated 36 women carriers of stress urinary incontinence, with an exercise program of the pelvic floor, supervised during six months, and obtained 67% cure or significant improvement.
