Abstract
OBJECTIVE: To compare the outcomes of robotic radical nephrectomy (RRN) to those of laparoscopic radical nephrectomy (LRN) for large renal masses.
METHODS: This was a retrospective analysis of RRN and LRN cases performed for large (≥ cT2) renal masses from 2004 to 2017 and collected in the multi-institutional international database (ROSULA: RObotic SUrgery for LArge renal masses). Peri-operative, functional, and oncologic outcomes were compared between each approach. Descriptive analyses were performed and presented as medians with interquartile ranges. Inverse probability of treatment weighting-adjusted multivariable analyses were used to identify predictors of peri-operative complications. Kaplan-Meier analysis and Cox regression models were used to assess survival outcomes.
RESULTS: A total of 941 patients (RRN = 404, LRN = 537) were identified. There was no difference in terms of gender, age, and clinical tumor size. Over the study period, RRN had an annual increase of 11.75% (95% CI [7.34, 17.01] p < 0.001) and LRN had an annual decline of 5.39% (95% CI [-6.94, -3.86] p < 0.001). Patients undergoing RRN had higher BMI (27.6 [IQR 24.8-31.1] vs. 26.5 [24.1-30.0] kg/m
CONCLUSIONS: This study represents the largest known multi-center comparison between RRN and LRN. The two procedures seem to offer similar peri-operative outcomes. Notably, RRN has been increasingly utilized, especially in the setting of more advanced and surgically challenging disease without increasing the risk of peri-operative complications.
