Herniation of a urinary bladder diverticulum: diagnosis and management of a fluctuating inguinal mass.

Inguinal herniation of a bladder diverticulum is a rare finding. The diagnosis should be suspected if the size of hernia is variable on urination. These patients may also experience obstructive voiding symptoms. Various imaging modalities may clarify the diagnosis. In our patient, intravenous urography precisely showed a bladder diverticulum in the right inguinal area. The patient underwent open simple prostatectomy and herniorrhaphy. He remains symptom-free on follow-up. 2017 BMJ Publishing Group Ltd.
