Urinary control relies on the finely coordinated activities of the smooth muscle tissue of the urethra and bladder, skeletal, voluntary inhibition, and the autonomic nervous system. Urinary incontinence can result from anatomic, physiological, or pathologic (disease) factors. Acute and temporary incontinence are commonly caused by childbirth, limited mobility, medication side effects, and urinary tract infections.
Chronic incontinence is commonly caused by bladder muscle weakness, pelvic floor muscle weakness, birth defects, blocked urethra, brain or spinal cord injury nerve disorders and vaginal prolapse.
Urinary Incontinence in Men and Women
Of the several types of urinary incontinence, stress, urge, and mixed incontinence account for more than 90% of cases. Overflow incontinence is more common in people with disorders that affect the nerve supply originating in the upper portion of the spinal cord and older men with Benign Prostate Hyperplasia (BPH).
