title: En Bloc Robot-assisted Laparoscopic Partial Cystectomy, Urachal Resection, and Pelvic Lymphadenectomy for Urachal Adenocarcinoma.
abstract: Primary adenocarcinomas of the bladder and urachus are extremely rare, accounting for 0.5% to 2.0% of all bladder malignancies. During fetal development, the urachus develops into the median umbilical ligament that stretches from the umbilicus to the bladder. Adenocarcinoma accounts for 90% of all cases of urachal carcinoma. There is no consensus regarding the management of urachal carcinoma. Although the preferred treatment is wide local excision with partial or radical cystectomy, bladder-sparing management is increasing. We report a case of robot-assisted laparoscopic partial cystectomy with en bloc resection of the urachus and bilateral pelvic lymphadenectomy for urachal carcinoma. The robot-assisted laparoscopic approach allowed us to minimize surgical morbidity, postoperative pain, and convalescent time while maintaining the oncologic principle of wide local excision.
