Abstract

PURPOSE: To evaluate the safety and clinical effects of extracorporeal magnetic innervation (ExMI) for urinary incontinence after radical prostatectomy.
MATERIALS AND METHODS
Thirty-two patients with urinary incontinence after radical prostatectomy were randomly assigned to receive either ExMI treatment or pelvic floor training alone. For the ExMI group, treatment was initiated 1 week after catheter removal and the treatment sessions were for 20 minutes, twice a week, for 8 weeks. For the control group, only pelvic floor muscle exercises were performed. Patients were followed up at 1 week and 1, 2, 3, and 6 months. Outcomes were assessed by 24-hour pad weight testing, the number of pads used daily, and a quality-of-life survey (I-QoL).
RESULTS
Leakage weight during the 24 hours after removing the catheter was 655g and 646g for the ExMI and control groups, respectively. At 1 month, it was 147g and 187g; at 2 months, 33g and 81g (p=0.001); and at 3 months, 9g and 45g (p=0.001), respectively. Finally, 6 months later, leakage weight was less than 10g in both groups. The number of pads used daily after removing the catheter was 4.2 and 4.1 for the ExMI and control groups, respectively. At 1 month, it was 1.5 and 1.8; at 2 months, 0.6 and 0.9 (p=0.033); and at 3 months, 0.1 and 0.6 (p=0.002), respectively. Finally, 6 month later, pads counts were 0 and 0.1. I-QoL scores decreased after surgery, but gradually improved in both groups. No other side effects or adverse events were observed.
CONCLUSIONS
ExMI provided earlier recovery of continence than in the control group after radical prostatectomy.
