Urachal adenocarcinoma is rare, accounting for only 10% of adenocarcinomas of the bladder and the prognosis of urachal adenocarcinomas is poor since most cases are detected late. Since urachal adenocarcinoma is a rare disease, no effective standard treatment has yet been established. However, in recent studies, resection of carcinoma is considered the only treatment considered for non-metastatic cases. Although for large sized urachal adenocarcinoma, open surgery or laparoscopic surgery is usually considered, we have recently experienced huge urachal carcinoma by robotic surgery. We used cystoscopy and the robot to assess the cancer margins and safely perform the operation. A 71-year-old man with a medical history of hypertension and arrhythmia visited our urology department with urachal cancer detected by computed tomography (CT). CT showed a lobulated low-density mass, most likely urachal carcinoma, abutting the anterior dome of the bladder and anterior abdominal wall. We performed preoperative cystoscopy to assess the extent of the protrusion of the urachal cancer into the bladder wall and the area requiring resection during surgery. We conﬁrmed the size and extent of the mass protruding into the anterior wall of the urinary bladder and Robot-assisted laparoscopic intracorporeal urachal mass resection and partial cystectomy using cystoscopy together was performed. After one month, the patient has no complications and no complaining symptoms complaints without any abnormal ﬁnding of follow up imaging test. Although more procedures must be performed to ensure the safety of robotic surgery as a treatment strategy for large urachal carcinomas, we conﬁrm that robotic surgery can replace open or laparoscopic surgery for such tumors.
