[Giant diverticulum of the bladder. A case report].

Vesical diverticula are a common pathology of the urinary bladder, generally secondary to cervico-urethral obstruction. Frequency of giant diverticula is not reported in the literature. The Authors present a case of giant vesical diverticulum (20 x 30 cm in diameter) due to prostatic adenoma in which any referable symptomatology was absent. The Authors debate the reasons for which progressive development of the diverticulum has been related with the improvement of the frequency and urgency previously presented by the patient.
