Most patients with urinary retention are elderly men with benign prostatic hyperplasia.1,2 The incidence and risk increase with age. There is a 20% recurrence within 6 months after an episode of urinary retention.2 Few data are available for women. In men with spontaneous urinary retention, the mortality rate at 1 year increases from 4.1% in patients age 45 to 54 years to 32.8% in those age 85 years and older.3
