[Bladder herniation].

Inguinal hernia of the bladder is uncommon. The diagnosis is frequently done during surgery. It can be evoked before surgery when the patient presents with irritative and obstructive lower urinary tract symptoms. Retrograde urethrocystography or computerized tomography confirm the diagnosis. We report a case of bilateral inguinal hernia involving the bladder at the right side in a 87 years old man who had a surgical history of transvesical adenomectomy of the prostate. The diagnosis was done on the retrograde urethrocystography. We performed bilateral herniorrhaphy with herniated bladder reduction. The postoperative history was uneventful.
