To assess the risk for postoperative acute kidney injury (AKI) after major urologic surgery for different intraoperative hypotension thresholds in form of time below a fixed threshold. We hypothesize that the duration of hypotension below a certain hypotension threshold is a risk factor for AKI also in major urologic procedures. ⋯ Our results suggest that avoiding intraoperative MAP lower than 65 mmHg and especially lower than 60 mmHg will protect postoperative renal function in cystectomy patients. The time between induction of anesthesia and surgical incision warrants special attention as a relevant share of hypotension occur in this period.
