Efficacy of transcutaneous functional electrical stimulation on urinary incontinence in myelomeningocele: results of a pilot study.
OBJECTIVE
To investigate the efficacy of transcutaneous functional electrical stimulation (FES) on voiding symptoms in children with myelomeningocele (MMC) suffering from neuropathic urinary incontinence.


METHODS
Six girls and 6 boys with moderate to severe urinary incontinence secondary to MMC were included. Median age of children was 5.04 (range: 3-11) years. They underwent a urodynamic study (UDS) before and 3 months after FES with special attention to detrusor leak point pressure (DLPP) and maximal bladder capacity (MBC). Daily incontinence score, frequency of pad changing, and enuresis were also assessed before and three months after treatment. Fifteen courses of FES for 15 minutes 3 times per week were performed with low frequency (40 Hz) electrical current, duration of 250μs, with hold and rest time of 2 seconds.


RESULTS
Nine children had improvement on urinary incontinence score, while three children had no improvement. Median DLPP was significantly increased from 38.5 (range: 12-50) cm H2O to 59.5 (range: 18-83) cm H2O (P = 0.003). MBC was significantly increased from median value of 155 (range: 60-250) mL to 200 (range: 110-300) mL (P = 0.007).


CONCLUSIONS
This is a pilot study showing that FES therapy might have positive effects on improvement of voiding symptoms of MMC children with neurogenic urinary incontinence in terms of daily incontinence score and UDS parameters.
