Plain English Summary
Background and study aims
A radical prostatectomy is an operation to remove the prostate gland in order to remove prostate cancer. The most common side effects of the operation are unintentional passing of urine (urinary incontinence) and problems with getting and keeping an erection (erectile dysfunction). This greatly reduces the patient’s quality of life. The aim of this study is to test a physiotherapy program for urinary incontinence three months after radical prostatectomy.
Who can participate?
Men aged over 18 who have undergone a radical prostatectomy and are experiencing incontinence and erectile dysfunction
What does the study involve?
Participants are randomly allocated to one of two groups. One group is treated with biofeedback pelvic floor training, a type of physical therapy that trains the brain and pelvic muscles to work together to tighten and relax the pelvic floor muscles. An anal electrode is used to record the activity of the pelvic floor muscles for 30 minutes. The patients also receive electrical stimulation for 15 minutes. The treatment lasts 45 minutes per day, 3 days per week. At home, patients also train their pelvic muscles through Kegel exercises throughout the day. The other group is treated according to the usual clinical practice, and an information sheet with Kegel exercises is provided after the operation. Both groups are assessed for incontinence, erectile dysfunction and quality of life at the start of the study and after 1 month, 2 months, 3 months (end of treatment), 6 months and 12 months.
What are the possible benefits and risks of participating?
The study will show whether physiotherapy can be used to treat urinary incontinence after prostatectomy. There is currently no standard treatment for this. Participants may benefit from an improvement in their urinary incontinence symptoms. The physiotherapy has no adverse effects. Sometimes it can cause discomfort due to the electrode being in the wrong position, but it can be fixed by adjusting the position of the electrode.

Post-prostatectomy urinary incontinence
Participants are assigned to the control group or intervention group through simple randomization. Doctors, patients and evaluators will not be blinded.
1. Intervention: Biofeedback is used for the pelvic floor training. An anal electrode records the activity of the pelvic floor muscles (30 minutes). Besides, the patients receive electrostimulation during 15 minutes. The treatment (biofeedback + electrostimulation) is 45 minutes per day (3 days per week). At home, patients train their pelvic muscles through Kegel exercises throughout the day.
2. Control: usual clinical practice. An information sheet with Kegel exercises is provided after the operation.
Patients are assessed at baseline, 1 month, 2 months, 3 months (end of treatment), 6 months and 12 months.
Primary outcome measure
Loss of urine, measured using the 24 h Pad test and 1 h Pad test, at baseline, 1 month, 2 months, 3 months (end of treatment), 6 months and 12 months
Secondary outcome measures
1. Quality of life and incontinence, measured using the ICIQ-SF questionnaire at baseline, 1 month, 2 months, 3 months (end of treatment), 6 months and 12 months
2. Erectile dysfunction, measured using the International Index of Erectile Function (IIEF-5) at baseline, 1 month, 2 months, 3 months (end of treatment), 6 months and 12 months
3. Life habits, measured using a urinary diary at baseline, 1 month, 2 months, 3 months (end of treatment), 6 months and 12 months
