Abstract
Introduction:
Urinary incontinence (UI) after prostatectomy is difficult to treat and causes profound adverse impacts on the individual's quality of life. The main clinical treatments available for post-prostatectomy UI consist of behavioral techniques and physical therapy techniques, such as exercises, electrical stimulation and biofeedback for pelvic floor muscles (PFMs).
Objective:
To investigate the effectiveness of PFM exercises with or without electrical stimulation for reducing post-prostatectomy UI.
Methods:
We included only randomized controlled trials (RCTs) which used PFM exercises with or without electrical stimulation. The search was conducted in August of 2013 in the databases of the U.S. National Library of Medicine (MEDLINE), Scientific Electronic Library Online (SciELO), Physiotherapy Evidence Database (PEDro) and Virtual Health Library (VHL). We searched for RCTs published between 1999 and 2013. As keywords for our search, we used the following descriptors from the Health Sciences Descriptors (DeCS): urinary incontinence, pelvic diaphragm, prostatectomy, pelvic floor exercises, electrostimulation and electrical stimulation. We also used the following descriptors from the Medical Subject Headings (MeSH): electrical stimulation, pelvic floor, urinary incontinence, prostatectomy, physiotherapy and exercise therapy.
Results:
Of the 59 RCTs found, 26 were excluded as duplicates, and 28 were excluded for not displaying a minimum score of 5.0 on the PEDro Scale, which left us with five RCTs.
Conclusion:
PFM exercises can be effective for treating UI after radical prostatectomy, especially if begun soon after surgery. Associating electrical stimulation with PFM exercises did not show additional benefit for treating urinary incontinence. However, the selected studies presented some methodological weaknesses that may have compromised their internal validity.
