Abstract
Two human cases are presented with cystoscopically visible cystic urachal remnants. The initial clinical findings, including bladder biopsies, were remarkably similar. Partial cystectomy with removal of the urachal cord alone clarified the actual disease. The inability to separate malignant and benign urachal lesions by other means suggests the necessity of total surgical extirpation. Perhaps this approach may result in an improvement in the generally poor prognosis for urachal carcinoma.
