Values are presented as medians with 25^th and 75^th percentiles, or as numbers (n) and percentages %.

^aP < 0.05 denotes significance.

¹Includes ultrasound evidence of 19 perinephric fluid collections not requiring intervention, and 32 perinephric fluid collections with intervention.

²4 graft failure attributed to thrombosis were due to technical difficulty: two allografts had single renal arteries and two allografts had two renal arteries, only one of which underwent arterial reconstruction in which the inferior portal artery was connected to the vein in a side-to-side anastomosis.

PACU: Post-anesthesia care unit; ICU: Intensive care unit; BP: Blood pressure; eGFR: Estimated glomerular filtration rate.
