Urethral diverticulum

Urethral diverticulum refers to a cystic cavity around the urethra that communicates with the urethra. It can be congenital or acquired. Congenital diverticulum is more common in women, mostly single, located between the urethra and vagina; in men it is mostly located on the ventral side of the urethra at the junction of the penis and scrotum. Diverticulum size and neck width are different, resulting in different degrees and symptoms of urinary tract obstruction.
