To compare the outcomes of intravesical injection of botulinum toxin A (BoNTA) with intravesical electromotive drug administration (EMDA) of BoNTA on urinary incontinence secondary to neuropathic detrusor overactivity (NDO) in children with myelomeningocele (MMC).
A total of 26 children with MMC (11 boys, 15 girls) who had urinary incontinence secondary to NDO were retrospectively enrolled in the study. Patients in EMDA group (n=14), using an electrode-catheter, 10 IU/kg of BoNTA were inserted into the bladder for EMDA without anesthesia and on an outpatient basis. The EMDA equipment was connected to the electrode of indwelling catheter and 2 dispersive electrodes, a pulsed current generator delivered 10-20 mA for 20 minutes. Patients in injection group (n=12) were received interavesical injection of 10 IU/kg of BoNTA via rigid cystoscope on an inpatient basis. All patients had been evaluated by a voiding diary, urodynamic study, renal and bladder ultrasounds before, 6 months and 1 year after the treatment.
Six months after the treatment, 12/14 (85.7 %) and 8/12(66.6%) patients in EMDA and injection groups respectively became completely dry between two consecutive clean intermittent catheterizations, which maintained in 11/14(78.5%) of patients in EMDA group compared to 6/12 (50%) of patients in injection group, 1 year after the treatment.
Patients in both groups improved after the treatment; however improvement in EMDA group was more prominent with better sustained effects. BoNTA/EMDA is a feasible, reproducible, cost benefit and pain free method as an outpatient basis and no need for anesthesia.
