Comparison between completely and traditionally retroperitoneoscopic nephroureterectomy for upper tract urothelial cancer

Comparison between completely and traditionally retroperitoneoscopic nephroureterectomy for upper tract urothelial cancer:

Abstract

Background

To evaluate the safety and efficacy of the completely retroperitoneoscopic nephroureterectomy (CRNU), a retrospectively comparative study between completely and traditionally retroperitoneoscopic nephroureterectomy (TRNU) was done in a single center.

Methods

From January 2014 to December 2014, 107 patients with upper tract urothelial cancer (UTUC) underwent CRNU. The kidney was retroperitoneoscopically dissected and the bladder cuff was cut by endoscopic gastrointestinal automatic stapler, and the specimen was removed from a 6-cm incision by posterior axillary line. Demographic, perioperative, and follow-up data were collected and compared retrospectively with 110 patients undergoing TRNU.

Results

The patients' characteristics between the two groups were not statistically different (p > 0.05), and all patients successfully received the procedure. The mean operative time (106 ± 37.9 versus 199 ± 69.1 min, p 

Conclusions

The CRNU using an endoscopic gastrointestinal automatic stapler to manage the bladder cuff is feasible and advantageous in decreasing the operative time, the blood loss, and the hospital stay. However, a larger sample and longer follow-up time will be still required.
