Comparative study of effects of extracorporeal magnetic innervation versus electrical stimulation for XXXX after radical prostatectomy.

@entity1 @entity322
OBJECTIVES: To perform a randomized comparative study to investigate the clinical effects of extracorporeal magnetic innervation (ExMI) and functional electrical stimulation (FES) on @entity322 after retropubic radical prostatectomy. METHODS: Thirty-six @entity1 with @entity322 after radical prostatectomy were randomly assigned to three groups (12 @entity1 each in the FES, ExMI, and control groups). For FES, an anal electrode was used. Pulses of 20-Hz square waves at a 300-micros pulse duration were used for 15 minutes twice daily for 1 month. For ExMI, the Neocontrol system was used. The treatment sessions were for 20 minutes, twice a week for 2 months. The frequency of the pulse field was 10 Hz for 10 minutes, followed by a second treatment at 50 Hz for 10 minutes. For the control group, only pelvic floor muscle exercises were performed. Objective measures included bladder diaries, 24-hour pad weight testing, and a quality-of-life survey, at 1, 2, and 4 weeks and 2, 3, 4, 5, and 6 months after removing the catheter. RESULTS: The leakage weight during the 24 hours after removing the catheter was 684, 698, and 664 g for the FES, ExMI, and control groups, respectively. At 1 month, it was 72, 83, and 175 g (FES versus control, P <0.05) and at 2 months was 54, 18, and 92 g (ExMI versus control, P <0.05) in the FES, ExMI, and control groups, respectively. Finally, 6 months later, the average 24-hour leakage weight was less than 10 g in all groups. Quality-of-life measures decreased after surgery, but gradually improved over time in all groups. No complications were noted in any of the groups. CONCLUSIONS: ExMI and FES therapies offered earlier continence compared with the control group after radical prostatectomy. We consider ExMI and FES to be recommendable options for @entity1 who want quick improvement of postoperative @entity322 .
