[Electromyographic evidence in conservative treatment of stress enuresis in women]

Electromyography (EMG) with needle electrodes of urethral and anal sphincters was performed in 32 patients with stress enuresis (SE). All the patients received conservative treatment as pelvic fundus exercise by Kegel (17 patients), use of vaginal cones (4 patients), ESMP-15-1 device electrostimulation (11 patients). In treatment failure, SE was corrected surgically. The response was assessed 8 weeks after the treatment. Satisfactory results were obtained in 23(72%) women. Reinnervation of urethral sphincter and the anus of different severity was found in 13(41%) and 30(97%) patients, respectively. Denervation in urethral and anal sphincter occurred in 4(13%) and 6(19%) patients, respectively. The comparison of the results of treatment and EMG findings has shown that good results were achieved only in patients with moderate reinnervation of the sphincters. Patients with denervation and/or severe reinnervation of the sphincters did not benefit from the conservative therapy or its result was minimal. It is shown that needle EMG is a reliable method of assessing the condition of urethral and anal sphincters and helps to make timely choice of SE treatment in women.
