The effect of pelvic floor muscle training in men with benign prostatic hyperplasia and overactive bladder

Background Men with overactive bladder (OAB) and benign prostatic hyperplasia (BPH), will have deterioration in the quality of life. Objective The aim of this study was to evaluate the effect of combining pelvic floor muscle training with the urgency suppression technique (PFMT-st) and silodosin in comparison with silodosin in men with benign prostatic hyperplasia (BPH) and overactive bladder (OAB) after 12 weeks of treatment. Patients and methods A total of 158 patients were randomized into two groups. The control group received oral silodosin at a daily dose of 8 mg. The experimental group was administered PFMT-st and silodosin. The evaluation methods included the number of voids and intensity of urgencies over 24 h using a micturition diary, the International Prostate Symptom Score (IPSS), the Overactive Bladder Questionnaire (OAB-q), and the patient global impression of improvement (PGI-I). Results 142 of 172 (86.6%) men were assessed (70 in the control group, 72 in the experimental group). The significant changes were in favor of the experimental group (p < 0.001) in the number of voids per 24 h (- 1.95 +/- 1.94 vs. - 0.90 +/- 1.44), the OAB-q symptom score (- 14.25 +/- 10.05 vs. - 9.28 +/- 10.60), the intensity of urgencies (- 0.97 +/- 0.53 vs. 0.24 +/- 0.57), the IPSS (- 4.59 +/- 3.00 vs. - 2.30 +/- 3.63), and in the PGI-I (2.24 +/- 0.79 vs. 3.60 +/- 0.92). Conclusions The addition of PFMT-st to silodosin treatment significantly improved OAB in men with BPH. This is the first study to confirm that PFMT-st should be the first-choice treatment for OAB in BPH.
