improved and he was weaned from ventilator after 4 days. The renal parameters normalized after 20 cycles of dialysis.Blood and urine cultures were negative.Post-dialysis the child developed polyuria with a daily urine output >8 mL/kg/day. The infant continued to have polyuria inspite of measures to decrease urine output. The infant developed metabolic alkalosis despite acute kidney injury and polyuria. The blood pressures were in normal range. The urine examination showed, red blood cells, granular casts and proteinuria. Urinary electrolytes values showed urine osmolality – 133.2 mOsm/kg (normal 500 – 850 mOsm/kg), urinary chloride–66 mEq/L (normal
