[Introduction]
Nephron-sparing surgery has become the favored treatment method for patients with small renal mass. Robot assisted partial nephrectomy (RAPN) has been covered under insurance policies in Japan since April 2016, soon after which the number of RAPN procedures have increased substantially. We compared the outcomes of RAPN between initial and subsequent cases at our institution.
[Method]
A total of 60 patients underwent RAPN at our institution from July 2016 to January 2018. The surgical procedures were performed by four surgeons, using the daVinci Si system. The initial cases were defined as the first 10 cases treated by each surgeon.
Trifecta was defined as a combination of warm ischaemia time (WIT) <25 min, negative surgical margins and no peri-operative complications.
[Results]
33 patients were initial cases, and 27 patients were subsequent cases. There was no statistically significant difference in preoperative characteristics except RENAL Nephrometry Score between these groups. In subsequent cases, RENAL Nephrometry Score was higher than initial cases (P=0.0374). Operative time, estimated blood loss, and rate of trifecta were 178.3 vs 183.0 min (P=0.7121), 131.7 vs 142.1 ml (P=0.8321), 66.7 vs 77.8 % (P=0.3420).
[Conclusion]
As the number of RAPN procedures increased, RAPN was performed for more complex tumor. However, there was no statistically significant difference in the operative time, estimated blood loss and trifecta outcomes between these groups.
