Material and Method: One hundred thirty five patients were randomized into the intervention group that concentration therapy was added to Kegel exercise, and control group that was Kegel exercise only, using the stratified randomization (stratified by taking the catheter off before and after discharge) and type of surgery. Incontinence was defined as a loss of urine equal or more than to 2 grams in one-hour pad test, before and after the test in each sample group. Follow-up results were obtained by phone visit at 3, 4, 5, 6, 8, 10, and 12 weeks after surgery.

Results: In the intervention group, 65 of 68 cases (95.6%) had continence in three months, compared to 48 of 67 (71.6%) in the control group, with significant statistical difference (p-value <0.001). The secondary result was the regularity in practicing. It was 80% in total. In the intervention group, 66 of 68 cases (97.06%) practiced compared to 34 of 67 (50.75%) in the control group, which was significant difference between the two groups.

Conclusion: Combined concentration therapy with Kegel exercise had significantly improved continence after radical prostatectomy.
