Abstract
Purpose: To describe a pure Retroperitoneoscopic Nephroureterectomy (RNU) with Distal Ureter And Bladder Cuff (DUBC) excision by a five ports method.
Methods: Standard RNU was carried out through four ports in the flank. The ureter was dissected caudally to the bladder cuff. The fifth trocar was placed at the distal end of a pre-planned Gibson’s incision to retract the ureter laterally for DUBC excision. For better visualization, the 0-degree retroperitoneoscope was shifted to the upper abdomen medial port. Ureter was dissected caudally till the ureterovesical junction. The bladder cuff was excised and clipping with an extra-large Hem-O-lock. A 5-cm incision between two trocars was made for specimen retrieval.
Results: Fifteen adult patients with Upper Tract Urothelial Cancer (UTUC) underwent the pure 5 ports RNU& DUBC excision. The mean estimated blood loss was 90 mL. The mean operating time was 220 minutes. The mean time to excise the DUBC was 30 minutes. The mean time to oral intake was at the post-operative second day. No one had local recurrence (follow-up: 1-15 months), except one had bladder recurrence, and the tumor was not located at the bladder cuff.
Conclusions: This 5-port method is technically simple for pure RNU and DUBC excision. It prevents tumor spillage, and avoids intra-operative patient repositioning.
