EXTRACORPOREAL MAGNETIC STIMULATION FOR THE TREATMENT OF OVERACTIVE BLADDER
Aims of Study
Magnetic stimulation continues to evolve as a non-invasive technique for stimulating the sacral nerves and pelvic floor and maybe activates the inhibitory reflex pathway to the detrusor via a mechanism similar to that of electrical stimulation. We investigated the efficacy and effects of extracorporeal magnetic stimulation (
Methods
A total of 26 patients (2 men and 24 women; mean age 39.5 years) with the overactive bladder symptom were studied. We applied 10Hz. Repetitive magnetic stimulation for 20 minutes, twice a week for 6 or 7 weeks. The magnetic stimulator unit was set on an armchair type seat and applied to patients fully clothed. Patients with severe vaginal atrophy, pelvic prolapse, cardiac disorder including on demand heart pacemakers, metallic implant, neurogenic bladder dysfunction, pregnancy, and previous pelvic radiation, were excluded from study. We asked patients to complete 3-day frequency/volume chart and answer a quality of life questionnaire before, 1, 3 , and 6 months after the last stimulation. Also, filling cystometry (CMG) was performed in 11 cases to evaluate urodynamic parameters before and 1 month after last stimulation.
Results
Among the 26 patients who were observed for up to 3 months, the mean number of voids daily decreased in 23 patients, increased one patient, and did not change in two patients. The mean number of voids daily significantly decreased by 38.1% (from 14.7±4.7 to 9.1± 8.4, p<0.001, Figure1). Before treatment 1 or more episodes of urge incontinence were presented in 8 patients (31%) and resolved in 4 cased after stimulation. In contrast, no significant change was observed in the mean of functional bladder capacity in before and after stimulation (310 ± 132.6 ml. vs. 330.1± 133.2 ml, p=0.176). Of 15 patients (93%) and the mean number of voids daily were significantly decreased from 15.8±5.3 to 9.9±2.3 (p<0.001).
