Also known as an overactive bladder with urinary leakage, this is the most common type for men. You experience a sudden urge to urinate and the bladder involuntarily expels urine. The urgency feeling can make it hard to make it to the bathroom in time. It can result in small, frequent losses between micturitions or complete bladder emptying. Different factors can cause this, such as an enlarged prostate, urinary tract infection, consumption of coffee or energy drinks, bladder stones, fragile post-menopausal mucous, gynecological conditions such as prolapse or ovarian tumor, and constipation.
