Most patients with urinary retention are elderly men with benign prostatic hyperplasia.1,2 The incidence and risk of this etiology increase with age, with 1 in 10 men in their 70s having an episode of acute urinary retention and 1 in 3 men having one in their 80s. There is a 20% recurrence rate within 6 months of an episode of urinary retention due to benign prostatic hyperplasia.2 Acute urinary retention in women is relatively uncommon, accounting for only 3 out of 100,000 cases of acute urinary retention each year, with the most common causes being bladder masses, gynecologic surgery, and pelvic prolapse.3
