Intraoperative data of 238 patients who underwent radical cystectomy

	All patients (N = 238)	No-AKI group (n = 147)	AKI group (n = 91)	P value
Operation time (min)	451.3 [387.0-501.5]	436.9 [378.0-477.0]	474.4 [414.0-548.0]	0.005
Crystalloid (mL)	3923.4 ± 1431.6	3900.0 ± 1466.0	3961.2 ± 1381.4	0.749
Colloid (mL)	810.7 ± 393.6	800.3 ± 367.6	827.5 ± 434.0	0.605
CVP (mmHg)*	7.2 ± 2.4	7.3 ± 2.4	7.0 ± 2.4	0.251
RBC transfused (U)	2.6 ± 2.3	2.7 ± 2.3	2.3 ± 2.2	0.116
Use of FFP	18 (7.6%)	11 (7.5%)	7 (7.7%)	0.570
Use of platelet concentrates	3 (1.3%)	2 (1.4%)	1 (1.1%)	0.674
Use of diuretics	12 (5.0%)	7 (4.8%)	5 (5.5%)	0.512

The data are expressed as mean ± standard deviation, number of patients (%), or median [first-third quartiles]. *Central venous pressure was evaluated as the average of three values (after induction of general anesthesia, at the end of bladder excision, and at the end of surgery). AKI = acute kidney injury; CVP = central venous pressure; RBC = red blood cell; FFP = fresh frozen plasma.
