Urethral diverticulum in a female child.
A urethral diverticulum in a female arises from the wall of the urethra and consists mainly of fibrous tissue lined with epithelium. It is uncommon, and usually presents between decades 3 and 5. Most patients present with non-specific, refractory, lower urinary tract symptoms, unrelated to the diverticulum size or number. The diverticulum may also present as a mass at the introitus. We report a case of urethral diverticulum in a female child that presented as an introital mass.
