Abstract

PURPOSE: The purpose of this study was to assess the treatment effect of extracorporeal magnetic innervation (ExMI) therapy, and determine how long the effect of this treatment lasts.
MATERIALS AND METHODS
Among the demonstrable stress urinary incontinent patients, 28 were selected. Before the ExMI therapy, voiding diary, incontinence episodes, pad test, and quality of life questionnaires were evaluated. The treatment was performed for 30 minutes, 3 times a week, for 6 weeks. All of the evaluations were repeated at the first and sixth months following treatment. The treatment outcomes were classified as: cure, good, fair, poor and failure, according to a new outcome score.
RESULTS
The overall cure rate was 35.7% (10/28) by the 1st month and 17.9% (5/28) by the 6th. From further a classification, the cure rate in grade I was 43.8 (7/16) and 25% (4/16) by the 1st and 6th months, respectively, and in grade II were 25 (3/12) and 8.3% (1/12) respectively. Incontinence episode was reduced from 4.2+/-2.8 to 1.5+/-1.5 and 2.8+/-2.3 by the 1st and 6th months, respectively. The urine loss was reduced from 21.0+/-31.4g to 6.0+/-8.2g and 14.0+/-24.7g by the 1st and 6th months, respectively. The results were statistically analyzed using Wilcoxon rank sum and Fisher's exact tests.
CONCLUSIONS
It was suggested that the ExMI therapy was an effective treatment for stress urinary incontinence, but its effect decreased over time. In order to sustain, or improve its effect, a regular interval, or prolonged ExMI therapy, would be need
