Causes of male bladder leakage include diabetes, stroke, diseases of the nervous system, and head or spinal injury, according to Everyday Health. An enlarged prostate gland may cause overflow urine incontinence. Surgical removal of the prostate gland may trigger stress incontinence.
Nervous system diseases, including Alzheimer's disease, Parkinson's disease and multiple sclerosis, affect the functioning of nerves that control the urinary tract, leading to uncontrolled urine flow, explains Everyday Health. Diabetes damages nerves that control the bladder, causing involuntary passage of urine. A person who suffers from stroke is likely to experience involuntary muscular contractions in the bladder. Injuries to the spine or head may malfunction the sphincter and nerves that control the bladder, causing the bladder to twitch convulsively.
The prostate gland helps the sphincter control the bladder, states Everyday Health. Removal of the gland, a procedure known as radical prostatectomy, leaves the control of urine to the sphincter alone. Strain or stress on the sphincter causes it to spasm, leading to involuntary urine leakage. Any damage to the nerve or sphincter aggravates the problem. Lifting of heavy items, sex and exercise exert pressure on the bladder.
Blockage in the urethra causes accumulation of urine in the bladder, a condition that generally occurs due to an enlarged prostate gland, according to Everyday Health. Bladder overflow leads to leakage of urine. Aging, inflammation of the prostate gland and prostate cancer may enlarge the prostate.
