Rapid rate magnetic stimulation of human sacral nerve roots can
reduce stress incontinence. OBJECTIVE: To test stimulation for urgency
incontinence due to lumbosacral plexopathy.
The authors studied patients
with intractable neurogenic urinary dysfunction due to lumbosacral nerve
injuries. Eligible patients were randomized to receive either real or sham
repetitive lumbosacral magnetic stimulation (rLMS; 15 Hz with a total of 1500
pulses/session) for 10 sessions. Evaluation was performed before starting
treatment, immediately after the 5th and 10th treatment session, and 1 month
later, using rating scales to score urinary dysfunction and a visual analogue
scale (VAS) to assess lower back pain. Posterior tibial nerve F-wave and
H-reflexes were tested before and after treatment. RESULTS: Both treatment and
control groups were comparable for baseline characters and sphincteric
disturbances. The mean number of voids and incontinence per 24 hours was
significantly reduced in patients who received rLMS.
The improvement was
maintained 1 month after the end of treatment. Patients receiving real-rLMS also
reported an improvement in VAS ratings. Improvement in F-wave and H-reflex
latencies after real stimulation (P = .002 and P = .036, respectively) was found
as well. CONCLUSION: rLMS at 15 Hz may improve urinary dysfunction secondary to
lumbosacral nerve injury. Further trials can determine the profile of patients
who may benefit and optimal stimulation parameters.
