Complex Monitoring of Biochemical and Radionuclide Parameters in Patients with Metastatic Renal Cell Carcinoma during Immunotherapy

Figure 2

A linearly smoothed 3D-surface showing the relationship between GFR in the Rehberg test and RN parameters, and GB₂₀. The blue arrow shows the development of CTIN (chronic tubulointerstitial nephritis) and an increase in the risk of RF, followed by a decrease in the urine excretion rate in the renal parenchyma (), the level of concentration of labeled urine that entered in the bladder within 20 minutes of the basic CSR test (GB₂₀), and GFR estimated by the Rehberg method ( = +0.4, ).
