A Urethral diverticulum is a condition in which an unwanted pocket, sac, or pouch, usually variably sized, forms in the urethra. Urethral diverticulum is a rare condition and more common in women aged between 40 and 70 years.

The urethra is a 4 cm long tube that carries the urine out of the body when a person urinates. Hence, during urination, due to the Urethral diverticulum, there might be chances of urine or pus getting filled into this sac or pouch, which can result in infections. A Urethral diverticulum can lead to a painful vaginal mass, urinary tract infections, and pain in the pelvic region.
