Radionuclide evaluation of renal function in essential hypertensive patients with chronic kidney disease

Aim. To carry out radionuclide evaluation of renal function in patients with arterial hypertension (AH) and chronic kidney disease (O(D). Subjects and methods. Thirty-one All patients with CKD were examined using dynamic nephroscintigraphy. A control group consisted of 8 CKD patients without AH. Results. The scintigraphic findings reflected statistically significant differences in renal secretory and excretory functions depending on the level of glomerular filtration rate (GFR) decrease in AH patients with CKD. If GFR was 30-59 ml/min, there was a deceleration in the secretory phase in the histogram; but when it was lower than 30 ml/min, the secretory function tended to accelerate, which appeared as a 3-fold reduction in achieving the peak radio tracer concentration (p<0.001). Conclusion. Dynamic nephroscintigraphy can detect early renal secretory and excretory dysfunctions and it is of prognostic value in assessing renal dysfunction, which necessitates early drug correction of revealed disorders.
