Complications of vesicoureteral reflux include continuously recurrent pyelonephritis, reflux nephropathy.

[Renal function after radical nephrectomy].

For determination of indications and contraindications to radical treatment of renal cell carcinoma, it is necessary to have information about functional activity of renal parenchyma of the contralateral kidney while methods of examination predicting functional activity of postoperative renal parenchyma after radical nephrectomy are not recently available. The Russian Research Roentgenoradiology Center utilizes 99m-Tc-DMCA static scintigraphy for assessing renal parenchyma function. This radiopharmaceutical demonstrates the highest tropism for epithelium of the proximal convoluted tubules, most functionally active nephron segment.
