Data are presented as n (%), mean ± SD, or median (IQR) unless otherwise stated. Sample sizes for longitudinal eGFR at 1 week, 1 month, and 3 months reflect available cases at each follow-up window due to attrition. ICG, indocyanine green; RAPN, robot-assisted partial nephrectomy; IQR, interquartile range; WIT, warm ischemia time; Clavien-Dindo, Clavien-Dindo classification system; Hb, hemoglobin; Cr, serum creatinine; eGFR, estimated glomerular filtration rate.
