Treatment of urinary stress incontinence (USI) by intravaginal electrical stimulation (IES) and pelvic floor physiotherapy represents an alternative to other therapies. The purpose of this work was to evaluate the effectiveness of this treatment studying patients with urinary incontinence.
From January 1998 to May 2000, 30 women (mean age 54 years) were studied. All patients presented USI and 70% incontinence by urgency, with an average follow-up of 7 months. Selection criteria were based on clinical history, objective evaluation of perineal musculature with perineometer, and urodynamic study. Treatment protocol consisted of 3 weekly sessions of IES for 14 weeks using INNOVA equipment. Physiotherapy was initiated in the fifth week of IES. A significant decrease in the number of micturitions and urgency were observed after treatment (p<0.01).
The pad test showed a reduction from 13.9 g to 5.9 g in urinary leakage after treatment (p<0.01). Objetive evaluation of perineal muscle strength showed significant improvement in all patients after treatment (p<0.01). Positive correlation was observed between maximum flow rate (Qmáx) and all three variables urethral pressure profile in rest and straining (stop test), and abdominal leak point pressure (ALPP). Positive correlation also observed between ALPP and stop test. Over one hundred different surgical and conservative treatments have been tried to manage USI. The majority of these procedures reveal that despite progress already made in this area, there is no ideal treatment . Satisfactory results can be achieved, with this method especially with patients who are reluctant to undergo surgery because of personal or clinical problems.
