Efficacy of transcutaneous perineal electrostimulation versus intracavitary anal electrostimulation in the treatment of urinary incontinence after a radical prostatectomy: randomized controlled trial study protocol

Abstract

Abstract Background Radical prostatectomy is the gold standard treatment for men with localized prostate cancer. This technique is associated with post-operative urinary incontinence. Pelvic floor physiotherapy is a conservative, painless and economical treatment for this specific situation. Kegel exercises and perineal electrostimulation are common techniques to train pelvic floor muscles. The perineal electrostimulation can be applied to the patient with surface electrodes or by an intra-cavitary anal probe. This study proposes that transcutaneous perineal electrostimulation is as effective as intra-cavitary electrostimulation in reducing urinary incontinence secondary to radical prostatectomy. The main objective is to compare the efficacy of the treatment with transcutaneous perineal electrostimulation versus the same intra-cavitary treatment to reduce the magnitude of urinary incontinence after radical prostatectomy, and the impact on the quality of life. Methods This single-blind equivalence randomized controlled trial will include 70 man who suffer urinary incontinence post radical prostatectomy. Participants will be randomized into surface electrodes group and intra-anal probe group. The groups will receive treatment for 10 consecutive weeks. Outcomes include changes in the 24-h Pad Test, and ICIQ-SF, SF-12 and I-QoL questionnaires. Clinical data will be collected at baseline, 6 and 10 weeks after the first session, and 6 months after the end of treatment. Discussion The results will allow us to prescribe the most beneficial perineal electrostimulation technique in the treatment of urinary incontinence derived from radical prostatectomy.
