N2 - We report on our initial data from a prospective study to determine the efficacy of high-frequency magnetic stimulation on the sacral root (MSSR) for the intractable post-radical prostatectomy, stress urinary incontinence (SUI). Methods: A total of 14 men with persistent SUI after a radical prostatectomy underwent treatment once every 2 weeks over a 40-week period for a total of 20 sessions. The outcome was assessed by these variables at baseline, at immediately after the first session, and at immediately after the final (20th) session. Results: Mean leak episodes (per day) consistently decreased after the first to the final session (from 6.1 ± 2.9 to 3.5 ± 2.6, and to 3.0 ± 2.3, P < 0.01), and it remained to be decreased following 2 months after the final session. The mean pad weight (per h) also decreased after the treatment (but no statistically significant change compared to the pretreatment level). The cystometric bladder capacity at the first desire to void and the capacity at the strong desire to void increased significantly following the high-frequency MSSR (first desire to void: from 146 ± 43 to 182 ± 52 mL; strong desire to void: from 224 ± 69 to 258 ± 60 mL, P < 0.01). No obvious complication was observed in any patients during or after the treatment. Conclusion: This study provides the preliminary evidence that high-frequency MSSR may potentially afford a useful option with minimal invasiveness for the patients with obstinate SUI after a radical prostatectomy.
