Duplication of urethra

Description

A condition caused by failure of the urethra to correctly develop during the antenatal period. This condition is characterised by the presence of a second passage from the bladder. This condition may present with double urinary stream, urination from the anus, or may be asymptomatic. Confirmation is through observation of a second urethra by imaging.
