Combined endoscopic and laparoscopic en bloc resection of the urachus and the bladder dome in a rare case of urachal carcinoma

Urachal carcinoma is a rare neoplasm treated with surgical resection. We report a case of adenocarcinoma of the urachus treated with a new surgical technique. In a 44-year-old man affected by urachal carcinoma we performed a combined endoscopic-laparoscopic surgical en bloc resection of the urachus and bladder dome. The procedure lasted 240 min, and no postoperative complications were recorded. The patient was discharged on fourth day and the catheter was removed on eighth day. Bladder capability resulted normal with no evident physical change. Multiple bladder biopsy and computed tomography scans at 6, 12 and 18 months proved negative.
