*Purpose: Robotic assisted live donor nephrectomy (LDN) is being increasingly adopted across transplant centers worldwide. Right LDN is perceived to be difficult due to anatomical factors. We aimed to study our outcomes after robotically assisted right and left living donor nephrectomies.

*Methods: We retrospectively analyzed all fully robotic LDN performed at our center between February 2016 and November 2019. The outcomes of right and left LDN were compared using two-sample t-test assuming unequal variances. A p-value < 0.05 was considered significant.

*Results: 132 fully robotic (non hand-assisted) LDN were performed (35 right versus 97 left). There were no differences between the age, sex or BMI of right versus left kidney donors. There was no difference between the mean operative times, blood loss or hospital stay between the two groups. The pre- and post donation (at discharge) serum creatinine was comparable between the two groups (Table 1). Intra-operative complications are summarized in table 2. There were no conversions to open surgery, re-operations, or mortality in either group. Out of 132 donors, 3 had chest pain and one had gluteal muscle rhabdomyolysis managed conservatively. There were 5 re-admissions (3.7%) for chylous ascites, pneumonia, urinary tract infection, urinary retention and pulmonary embolus with previously undiagnosed PFO. Overall, nausea was the most common complication (18.2 %).

*Conclusions: Our initial experience indicates that robotic assisted live donor nephrectomy can be can be safely performed with excellent outcomes. Although right donor nephrectomies had a higher incidence of intra-operative complications, there were no statistically significant differences in the overall outcomes of right versus left robotic donor nephrectomies at our center.
