Chung JS, Hong SK, Lee SC, et al. - In order to ascertain if long-term renal function after partial nephrectomy (PN) for patients with pre-existing chronic kidney disease (CKD) could be improved with a short warm ischemic time (WIT), researchers here examined renal function after PN according to WIT duration in patients with stage III CKD. Among 277 patients with stage III CKD who underwent PN during 2004–2017, they created two matched groups of 85 patients each: Group A (WIT of < 25 min) and Group B (WIT of ≥ 25 min). Outcomes of these groups revealed no association of a short WIT with better postoperative kidney function or survival after PN in cases with stage III CKD.
