Rehabilitative therapy of the perineum (FKT, SEF and biofeedback) represents an efficient method in the treatment of urinary stress incontinence without resorting to a complete uro-genital prolapse, as in patients with urethral instability and/or incontinence. One hundred twenty-one women, 55 with urinary stress incontinence (USI), 20 with urge incontinence (UI) and 46 suffering from both types of incontinence, underwent rehabilitative therapy. On each patients the following tests were carried out: an internal test, a urodynamic test (uroflowmeter, PPU, cystomanometry and pessure/flow study), a meter UEC, situated at the bladder neck, anterior and posterior urethra, both clinostatic and orthostatic, urine test with urinoculture and a pap-test. The aim of this study is that of establishing if it is possible a) to simplify the rehabilitative sitting using only FKT with weekly treatment; b) to treat women suffering from urge incontinence or from both types, but with bladder stability (standard cystomanometria) with FKT and Ditropan (1 tablet 3 times daily for weeks therapy). One group of patients underwent rehabilitative therapy while another group underwent traditional therapy, for a minimum of 12 sitting, using also electric functional stimulation (SEF). Of 121 women who underwent rehabilitative therapy, 90 (74.4%) were healed, 30 (24.7%) improved and one (0.9%) showed no signs of improvement. Patients treated with FKT, or FKT and made as good if not better grogress than those who attended more sittings and/or underwent SEF.(ABSTRACT TRUNCATED AT 250 WORDS)
