A case of bladder and colonic duplication

الملخص EN

Duplication of the bladder is a rare congenital anomaly with an unknown embryological basis.

A 12-year-old boy with dysuria was found to have a tri-radiate external urethral meatus instead of a vertical slit.

Cystourethroscopy revealed two bladders with bifid proximal urethra.

Magnetic resonance imaging (MRI) revealed duplication of colon and bladder.

He did not have any symptoms related to the urinary tract.
