Increase of Neutrophil-Lymphocyte Ratio (NLR) during Urologic Laparoscopic Surgery with Intraoperative Complications in Dr. Sardjito Hospital

Laparoscopy is a minimally invasive surgery using advanced technology, so the resulting surgical wound is smaller than conventional surgery. Laparoscopy, especially in the field of urology, is known to cause complications in patients. Intraoperative complications will cause physiological stress that causes an inflammatory response in the body. Neutrophils are one of the most important cells in producing the inflammatory response in the acute phase. Meanwhile, lymphocytes are the main cellular components of the immune system that are mediated by T cells and humoral cells. This study was conducted retrospectively and reviewed the patient's medical record data from intraoperative to outpatient admission. The sample included 71 patients who underwent laparoscopic urology in 2017-2019. There was a difference in NLR values between pre surgery and post-surgery (p < 0.05). It is known that the postoperative NLR value is higher than preoperative. In addition, it was known that there were differences in postoperative NLR values between patients who did not experience complications and those who had complications (p < 0.05). Where there is an increase in the postoperative NLR value in patients with complications, intraoperative complications lead to increased NLR. The greater the physiological stress experienced, the higher the NLR value. Increased NLR reflects poor output.
