Background: The risk of renal cell carcinoma (RCC) development in the native kidney of patients on dialysis or with a renal transplant is increased compared to the general population. This study examines perioperative outcomes of laparoscopic radical nephrectomy (LN) in dialysis patients or renal transplant patients compared to normal controls. Methods: Four hundred twelve consecutive LN were evaluated (July 2007 to October 2018). Patients were divided into three groups (control, dialysis, and transplant). Perioperative outcomes, including operating room time (OT), postoperative complications, hospital length of stay, and 90-day readmission rates, were evaluated for the three groups. Results: There were 62 patients in the dialysis group, 20 renal transplants, and 330 normal controls. Dialysis patients were younger (median: 58 years versus 67 years; P = .002) and predominantly male (73% versus 59%, P = .047). Dialysis patients compared to controls had shorter total OT (median: 133 versus 149; P = .022), more papillary RCC (27% versus 10%; P < .001), and fewer high grade tumors (73% [8/11] versus 94% [100/106]; P = .038). Renal transplant patients had a higher rate of 90-day readmission (20% versus 6%; P = .034) and more papillary RCC (30% versus 10%; P = .016) compared to controls. Conclusion: LN on dialysis patients does not alter expected perioperative outcomes compared to a large cohort of control LN. LN on renal transplant patients carries a higher 90-day readmission rate than control LN.
