Introduction & Objective : We report a comparative analysis of outcomes in patients who underwent excisions of renal hilar tumors using both open and robotic approaches.


Methods : We retrospectively reviewed 164 robotic and open patients who underwent partial nephrectomy (PN) of renal hilar tumors between 2011 and 2016. "Trifecta" was defined as negative surgical margins, no complications, and a GFR preservation of >90% at last follow-up. Inverse probability of treatment weighting (IPTW) was applied to equilibrate treatment groups, minimize selection bias, and optimize inference on the basis of each patient's clinicodemographic characteristics.


Results : 100 robotic and 64 open patients had sufficient data for IPTW. After weighting, there were no statistical differences in baseline characteristics between the two groups (p<0.05). On adjusted analyses, robotic partial nephrectomy achieved equivalent rates of trifecta to open surgery (26.4% vs. 14.8%, respectively, p=0.387). There were no differences between robotic and open cohorts for negative margin rates (92.5% vs. 84.5%, p=0.124), absence of complications (73.7% vs. 61.3%, p=0.587), or GFR >90% (39% vs. 28.1%, p=.111). The robotic cohort had a shorter mean length of stay (3.8 vs. 5.0 days, p=0.012), and no difference in estimated blood loss (253.3 vs. 357.1, p=0.091) or operating time (199.8 vs. 200.4, p=0.961).


Conclusions :

In our analysis both open and robotic partial nephrectomy for hilar tumors were equally likely to achieve the "trifecta" outcome with a shorter mean length of stay in the robotic cohort. The robotic approach for these complex tumors is safe and feasible.
