Difficulty urinating due to obstruction of the urethra. This usually occurs in men with an enlarged prostate, or can be due to urethral stricture. To release urine, this mechanism relaxes, allowing the urine to flow from the bladder to the outside of the body. If this mechanism is damaged, it could cause urine to be released involuntarily. Occurs when the urethra narrows.
Urge incontinence causes a person to release urine involuntarily due to detrusor overactivity.
An intense and sudden desire to urinate. The urinary tract is the pathway the urine follows to leave the body. The pathway involves the kidneys, ureters, bladder and urethra. Cystitis, otherwise known as a bladder infection, is common in women due to the short urethra, which provides a shorter barrier to bacteria. Bladder infections in men are usually caused by urethral obstruction.
