This study evaluates whether surface perineal stimulation is as effective as anal stimulation in reducing urinary incontinence secondary to radical prostatectomy.

Half of participants will receive a treatment with surface perineal stimulation, while the other half will receive a treatment with anal stimulation.

Pelvic floor muscle training is the most common non-invasive intervention for urinary incontinence secondary to radical prostatectomy. Perineal stimulation has a significant positive impact on the early recovery of urinary continence after this intervention.

The perineal stimulation can be applied with surface electrodes or with an intra-cavitary probe placed in the anus. The two techniques are commonly used. Each techniques stimulates different anatomical points of perineum, and it is a question if both have the same effectiveness or, one of the two techniques has greater effect than the other.

Inclusion Criteria:

• Having undergone a radical prostatectomy surgical procedure.
• Presenting involuntary urine losses after radical prostatectomy intervention. (IU grade I, II or III)
• Do not exceed the year since the surgical intervention.
• Accept to participate in the study and grant signed informed consent.

Exclusion Criteria:

• Follow a pharmacological treatment for the UI.
• Presenting anatomical malformations of the pelvic floor musculature.
• Carry pacemaker.
• Present anal fistulas.
• suffer from serious psychic disorders.
• Presenting lower urinary tract infections.

As it is a prostatic pathology, only men participate in the study
