ASA American Society of Anesthesiologists physical status classification; RFRI Respiratory Failure Risk Index (Gupta); ARISCAT Score Assess Respiratory Risk in Surgical Patients in Catalonia; BMI body mass index, IBW ideal body weight (calculation was based on the ARMA Trial of the ARDS Network Investigators); PEEP positive end-expiratory pressure; SD standard deviation; IQR interquartile range
aDue to intraoperatively observed intraabdominal status or excessive propagation of bladder tumor, only radical cystectomy and ureterocutaneostomy was performed without ileal conduit
