Introduction:

To compare the effects of different pelvic floor muscle training (PFMT) modes on improving urinary incontinence (UI) recovery in prostate cancer (PCa) patients after radical prostatectomy (RP).

Material and methods:

PCa patients who underwent RP were prospectively enrolled and randomly divided into a standard PFMT (S-PFMT) group, a somatosensory interactive PFMT (SI-PFMT, an enhanced PFMT) group, and a standard PFMT combined with pelvic floor muscle magnetic stimulation (S-PFMT+MS) group. Post-RP UI status was evaluated through Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) scores and 1-hour pad test.

Results:

A total of 101 subjects were enrolled, including 48 in the S-PFMT group, 39 in the SI-PFMT group, and 14 in the S-PFMT+MS group. All groups showed significant improvement in ICIQ-UI SF scores at 3- and 6-months post-RP compared with baseline level (all p < 0.001). At 6 months post-RP, significant amelioration of the 1-hour pad test result was achieved (p = 0.012). The patients in the S-PFMT+MS group exhibited significantly better UI improvement (ICIQ-UI SF scores) compared to the other two groups (p = 0.033 vs. S-PFMT; p = 0.011 vs. SI-PFMT) at month 6. Bayesian survival analysis supports the superior efficacy by point estimate of the S-PFMT+MS intervention over an extended period.
