Evaluation of the subjective and objective effect of maximal electrical stimulation in patients complaining of urge incontinence.

Abstract

Background: Favorable results have been reported following Maximal Electrical Stimulation (MES) of patients with urgency and urge incontinence. However, patient groups have often been mixed and outcome measures poorly defined. We therefore wanted to treat a homogeneous patient population with MES and evaluate the effect by defined subjective and objective outcome measures.

Methods: Eighteen female patients complaining of urge incontinence had MES performed. Before and 3 months after MES, the patients performed a 24 hour micturition chart and pad test. They indicated on a visual analogue scale their subjective degree of urgency and leakage and had an ambulatory urodynamic monitoring performed. Nine months after MES the patients were asked whether their urge incontinence was less, equal or more troublesome than before MES.

Results: After MES the patients indicated significantly less urgency and leakage. A significant difference was not found in any of the objective outcome measures after MES. Six out of 18 patients (33%) found their urge incontinence less troublesome 9 months after MES, while 12 (66%) found it unchanged or more troublesome than before.

Conclusions: Significantly subjective effect was found following MES. However, none of the objective outcome measures were significantly improved. We were disappointed by the results and have stopped using the method.
