Study of the effectiveness of different pelvic floor muscle training methods for improving urinary incontinence in patients with prostate cancer after radical prostatectomy.

Introduction To compare the effects of different pelvic floor muscle training (PFMT) modes on improving iatrogenic stress urinary incontinence (SUI) recovery in prostate cancer (PCa) patients after radical prostatectomy (RP). Methods PCa patients who underwent RP were prospectively enrolled and randomized into standard PFMT (S-PFMT) group, somatosensory interactive PFMT (SI-PFMT, an enhanced PFMT) group, and standard PFMT combined with magnetic stimulation (S-PFMT+MS) group. SUI status was evaluated through the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) scores and 1-hour pad test. Results 101 subjects were enrolled, including 48 in S-PFMT group, 39 in SI-PFMT group, and 14 in S-PFMT+MS group. All groups showed significant ICIQ-UI SF score improvement at 3 and 6 months post-RP compared with baseline (all  < 0.001). At 6 months post-RP, significant improvement of 1-hour pad test result was observed ( = 0.012). Compared with those in the other two groups, patients in the S-PFMT+MS group exhibited significantly better SUI improvement ( = 0.033 . S-PFMT;  = 0.011 . SI-PFMT) at 6 months. Bayesian survival analysis revealed the superior efficacy of the S-PFMT+MS intervention over an extended period. Conclusions: PCa patients may benefit from magnetic stimulation in addition to standard PFMT for post-RP SUI recovery. CLINICAL TRIAL REGISTRATION: HKUCTR-3029, https://www.hkuctr.com/.
