Robot-Assisted Partial Cystectomy versus Open Partial Cystectomy for Patients with Urachal Cancer.

Introduction: Localized urachal cancer (UrC) can be treated with an open partial cystectomy (OPC) with en bloc resection of the urachal remnant and umbilicus. Robot-assisted partial cystectomy (RAPC) is an alternative approach, of which its safety and efficacy for UrC remains to be determined. In the present study, we analyze these outcomes after RAPC, compared with OPC.
