Robotic Partial Cystectomy for Primary Urachal Adenocarcinoma of the Urinary Bladder

We present the largest reported consecutive series on robotic partial cystectomy in the management of patients with primary urachal adenocarcinoma. Eight patients with primary urachal adenocarcinoma of the urinary bladder underwent a robotic partial cystectomy. The mean operative time, including trocar placement as well as robotic docking and closure was 184 minutes (range 130-240 minutes). The mean console time was 120 minutes (range 70-170 minutes). The mean estimated blood loss was 50 ml. There were no conversions to open surgery. The mean hospital stay was 4 days (range 3-7 days). Drain removal was performed at postoperative day 2.5 (range 2-3 days). Each patient underwent postoperative cystography on day 10 postoperatively and no patients had evidence of extravasation. There were no major complications. Histological analysis of all tumors confirmed primary urachal adenocarcinoma of the urinary bladder. There were no positive surgical margins. At a mean follow up of 32 months none of the patients have had a disease recurrence with any evidence of disease recurrence. Our initial data indicates that with robotic partial cystectomy for primary urachal adenocarcinoma of the urinary bladder is a safe surgical and oncological procedure. However, longer follow up and larger patient numbers are required to validate this further.
