Summary:

Objective: to assess the possibility of using the markers of acute kidney injury to predict the preoperative risk for the subsequent decline in glomerular filtration rate in different types of surgical treatment of renal cell carcinoma (RCC). Material and methods. 60 patients with histologically confirmed RCC T1-3M0N0 operated in the clinic of urology of Saratov State Medical University n.a. V. I. Razumovsky in the volume of nephrectomy or partial nephrectomy. Before surgery all patients underwent standard examination intended for patients with kidney tumors: ultrasound, MRI, excretory urography and dynamic renoscintigraphy, the perioperative values of serum creatinine and glomerular filtration rate were determined. Using the method of immuno-enzymatic analysis the concentrations of excreted with the urine NGAL and IL-18 in serum samples at the preoperative stage, after 5 days and after 1 month of postoperative follow-up were investigated. Differences in clinical data and clinical variables were compared by using Spearman rank correlations and t-test. Results. The determined parameters of acute kidney injury markers IL-18 and NGAL in the early postoperative period were increased in patients after open nephrectomy. Moreover, the correlation analysis according to the Spearman method revealed a strong significant correlation between the preoperative levels of IL-18 and GFR after surgery (r=1; p<0.05). Conclusion. Laparoscopic resection of RCC is the method of choice for surgical treatment of RCC. As a predictor of adverse prognosis, the level of IL-18 in serum may be used. Its increase correlates with a decline in renal function in the postoperative period, and according to some reports, IL-18 also is an independent predictor of adverse prognosis in patients with a localized RCC.
