Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators aimed to show the renal damage caused by increased intra-abdominal pressure in laparoscopic surgeries and to investigate whether its reflection on NIRS would be clinically effective.The main question it aims to answer are:

Does pneumoperitoneum cause renal damage?

NRS monitoring will be performed in patients undergoing laparoscopic surgery. Preoperative and postoperative blood tests will be performed at certain hours. N-GAL, urea and creatinine values will be recorded.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Renal NIRS monitoring will be performed in patients undergoing laparoscopic cholecystectomy surgery. Age, gender, BMI, ASA scores, hemogblin/hematocrit values, intraoperative hemodynamic parameters, NIRS values, N-GAL (preoperative, 2nd hour and 24th hour), urea/creatinine (preoperative, postoperative 24th hour) values of the patients will be recorded. .

Before the general anesthesia is performed, the renal tissues of the patients will be visualized by ultrasound, the skin-renal cortex distances will be measured, and suitable patients will be included in the study. Basal rSO2 values will be recorded by placing NIRS probes under the 10-11. intercostal space in the bilateral posterior lateral flank region.
