ABSTRACT
PURPOSE:
To compare the 5-year oncologic and functional outcomes of robot-assisted laparoscopic partial nephrectomy (RALPN) and laparoscopic partial nephrectomy (LPN) as treatment for localized renal cell carcinoma (RCC). MATERIALS ANDMETHODS:
We analyzed the records of 181 patients with localized RCC who underwent RALPN (n=97) or LPN (n=84) between 2007 and 2011. Demographic and preoperative data with estimated glomerular filtration rate (eGFR), intraoperative data including warm ischemic time (WIT) and complications, oncologic outcomes (recurrence, metastasis), and rate of eGFR preservation at most recent follow-up were examined.RESULTS:
WIT was shorter in the RALPN group (27±9.1 minutes) than the LPN group (31±10 minutes, p=0.019). Intraoperative complication rates were also lower in RALPN patients than LPN patients (4.1% vs. 14.3%). The eGFR preservation rate was higher in the RALPN group (84.6%) than in the LPN group (81.5%, p=0.049). Particularly, a relatively high difference in the eGFR preservation rate was observed in the RALPN group compared with the LPN group according to R.E.N.A.L. score 7–10 values (RALPN, 86.5±12.9 vs. LPN, 76.7±16.0; p=0.003). During the follow-up period, there was no local recurrence in either group and distant metastases only occurred in one patient in the RALPN group and in 2 patients in the LPN group.CONCLUSIONS:
RALPN and LPN showed similar 5-year oncologic outcomes, but RALPN was superior to LPN in terms of WIT, intraoperative complications, and long-term eGFR preservation rate, especially in complex cases.
