Purpose of the study. To assess the state of renal function in the application of therapeutic plasmapheresis in order to correct the disorders accompanying the development of preclinical stage of AKI in patients after partial nephrectomy under conditions of warm ischemia. Patients and methods . We examined 119 patients (average aged 57.6±7.8 years) from 2018 to 2019, who underwent open or laparoscopic kidney resection for cancer according to elective indications and with the usage of standard WIT technique within 15-21 minutes. Patients with a high risk of developing a clinical stage of AKI (n=21) were divided into 2 groups: in group I (n=10), patients continued to receive standard nephroprotective therapy, in group II (n=11), 24 hours after surgery, therapeutic plasmapheresis was performed according to the TPE (Therapeutic plasma exchange) protocol. During 7 days after the surgery patients in both groups were monitored daily for the rate of hourly diuresis, serum creatinine, and creatinine GFR. The presence of significant differences in the groups was evaluated using the STATISTICA 12.6 software package and the differences between the samples were considered significant at p<0.05. Results. The development of the clinical stage of AKI in group I was detected in 80.0 % of cases, in group II in 9.0 % of patients (p=0.0019). The rate of diuresis in group II was significantly higher: by more than 2 times by day 3, by 90.0 % on day 4, by 81.4 % on day 5, by 36.8 % on day 6, and by 25.4 % on day 7 (p<0.05). The average increase in creatinine in group I was significantly higher: more than 5 times on day 5 and more than 4 times on day 6 and 7 of the study (p<0.05). GFR in group II was significantly higher on day 3 (65.3 %), day 5 (54 %), day 6 (39.2 %) and day 7 (50 %) (p<0.05). Conclusion. Therapeutic plasmapheresis is highly effective in the correction of renal function disorders after kidney resection under WIT conditions and demonstrates an advantage in reducing the risk of developing a clinical stage of AKI in comparison with preventive measures that include standard nephroprotective infusion therapy.
