Effect of preoperative biofeedback/pelvic floor training on continence in men undergoing radical prostatectomy.

Author information

University of Chicago Hospitals, Chicago, Illinois, USA.



To determine whether preoperative biofeedback training improves urinary continence overall or the rate of return of continence in men undergoing radical prostatectomy.


One hundred men scheduled to undergo radical prostatectomy were randomized to receive graded pelvic muscle exercise training with biofeedback 2 to 4 weeks before surgery or to a control group performing pelvic muscle exercises without biofeedback. The biofeedback group was instructed to continue exercises four times per day until surgery and to resume exercises when the urethral catheter was removed following surgery. The control group received written and brief verbal instructions in pelvic muscle exercises before surgery and again after catheter removal. Urinary continence was assessed by personal or phone interviews.


Six months following surgery, the continence rates, as defined by the use of one pad or less per day, were 94% (44 of 47) and 96% (48 of 50) in the biofeedback and control groups, respectively (P = 0.596). Also, the rate of return as determined at time points 1, 2, 3, and 4 months after surgery was not significantly different between the two groups.


Preoperative biofeedback training did not improve the outcome of pelvic muscle exercises on overall continence or the rate of return of urinary control in men undergoing radical prostatectomy.
