Evaluation of Renal Oxygenation by NIRS in Pediatric Endourologic Stone Surgery

After the positions of the renal NIRS probes are confirmed by ultrasonography, the average value of the three measurements will be taken and the regional oxygen saturation index (rSO2) will be accepted as the initial value.

Pre- and Postoperative hemoglobin (Hb), hematocrit (Htc), leukocyte (WBC), blood urea nitrogen (BUN), serum creatinine (sCr), procalcitonin, interleukin-6 and CRP values will be recorded.
