The Dynamics of Acute Renal Impairment Markers During a Surgery for Kidney Cancer
Abstract
The purpose of the study is to investigate the effect of epidural block on the functional state of the kidneys in patients with localized cancer during kidney resection under the conditions of warm ischemia.Materials and methods. We examined 45 patients (25 men and 20 women) with a localized kidney cancer (T1N0M0) aged 56.5±8.7 years. All the patients underwent kidney resection performed under conditions of warm ischemia (15—20 minutes). Patients were divided into 2 groups: the main group (25 subjects) in which the perioperative epidural block was applied and the reference group (20 patients) without the epidural block. The following parameters were tested in blood and urine using the ELISA technique: cystatin C, L-FABP, KIM-1 , IL-18, and GFR. The test was carried out 1 hour prior to surgery, 20 minutes after the warm ischemia stage, and on Days 1 and 3. Based on the baseline cystatin С level, the patients in each group were divided into 2 subgroups: subgroup 1 —cystatin C is 1000 ng/ml and lower; subgroup 2 — more than 1000 ng/ml. The statistical processing of the findings was performed using the Statistica 6.0 software based on the t-test for two independent samples. Differences were considered to be statistically significant at P<0.05.Results. It has been demonstrated that functional parameters of kidneys were recovered to the baseline values by the 3rd day after the kidney resection under the warm ischemia due to perioperative epidural block. Impairment of the tubulointerstitium and glomerular apparatus were observed in the reference group. GFR values in the patients of the main group were within normal limits by Day 3, whereas in the patients of the GFR was lower by 38.8% as compared to the baseline (P<0.05).Conclusion. The use of the perioperative epidural block in patients with localized kidney cancer who underwent the organ resection under the warm ischemia demonstrated the nephroprotective effect, while maintaining the functional parameters of kidneys at the baseline level.
