Table 2. Outcomes of the study patients.
| Outcomes | AKI according to serum creatinine (n = 18) | AKI according to urine output alone (n = 38) | No AKI (n = 24) | P value |
|---|---|---|---|---|
| AKIN stage 1 (%) | 17/18 (94.4) | 8/38 (21.1) | 0/24 (0) | <0.001 |
| AKIN stage 2 (%) | 1/18 (5.6) | 21/38 (55.3) | 0/24 (0) | |
| AKIN stage 3 (%) | 0/18 (0) | 9/38 (23.4) | 0/24 (0) | |
| Mortality at hospital discharge (%) | 5/18 (27.8) | 0/38 (0) | 1/24 (4.2) | 0.001 |
| Dialysis-dependence in survivors at hospital discharge (%) | 0/13 (0) | 0/38 (0) | 0/23 (0) | NS |
| Absence of renal recovery at hospital discharge* (%) | 1/12 (8.3) | 1/38 (2.6) | 1/23 (4.3) | 0.69 |
| Hospital stay (days) | 5.5 (IQR 4.0–14.75) | 6.0 (IQR 4.0–13.0) | 5.0 (IQR 3.0–12.0) | 0.39 |
*absence of renal recovery defined as a difference between creatinine at hospital discharge and reference creatinine >27 μmol/l in survivors
