Pelvic Floor Magnetic Stimulation Treats Voiding Dysfunction

NEW YORK (Reuters Health) - Recent study findings suggest that
extracorporeal pelvic floor magnetic stimulation may be an effective
treatment in children with voiding dysfunction.
In a prospective study, Dr. Sang Won Han and colleagues
from Yonsei University College of Medicine, in Seoul, Korea,
examined the effect of extracorporeal pelvic floor magnetic
stimulation in 42 children diagnosed with an overactive bladder.
Complete follow-up data were available for 34 children.
were grouped according to their symptoms into the following
categories: urge incontinence only, defined as involuntary
urinary leakage after urgency; monosymptomatic nocturnal
enuresis, defined as nocturnal enuresis with no daytime
incontinence; or not monosymptomatic nocturnal enuresis, defined
as daytime incontinence plus nocturnal enuresis.
researchers assessed clinical variables using a voiding diary
before and after magnetic stimulation. Magnetic stimulation was
administered twice a week for 4 weeks using a size-adjusted
magnetic chair. Each session lasted 20 minutes. Results of the
study are published in the June issue of the British Journal of
The mean daily voiding frequency
decreased significantly in the urge incontinence-only and
not-monosymptomatic nocturnal enuresis groups after all
functional magnetic stimulation treatment sessions. A
significant decrease in the frequency of urge incontinence was
also observed in these groups. Children in the monosymptomatic
nocturnal enuresis group had a significant decrease in voiding
The researchers observed significant increases
in the mean functional bladder capacity in all of the groups.
There were no significant changes in the mean volume or
frequency of nocturnal enuresis in the not-monosymptomatic
nocturnal enuresis or monosymptomatic nocturnal enuresis groups,
Dr. Han and colleagues note.
The authors call for further
studies on the duration of stimulation, combined treatments, and
controlled studies with a sham-stimulation group. "Future
studies on neuromodulation for voiding dysfunction in children
must consider these aspects," they conclude.
