Vesicoureteral reflux in children without diagnostics and correct treatment could result in chronic renal failure. This prognosis forces to look for new more informative methods of diagnostics. The authors of the article conducted research to assess the reliability of key methods — radionuclide and radiological methods. The results obtained indicate the need for a differentiated approach to each child and advisability of comprehensive examination of a child using various methods not only to identify the presence of reflux, but also its duration, intensity in order to select the right tactics of treating the patient. Key words: vesicoureteral reflux, diagnostics, dynamic nephroscintigraphy, radionuclide cystography, voiding cystography, children. (Pediatric Pharmacology. – 2010; 7(3):95-97)

Vesicoureteral reflux is one of the most widely spread lower urinary tract diseases among children, which is the primary reason for the disturbed urodynamics and development of the chronic pyelonephritis. As a consequence, the contamination of the urinary tracts may be the reason for further development of the chronic kidney disease, renal hypertonia and may inevitably lead to disability. The modern diagnostics of the vesi coureteral reflux is very important for the adequate conservative and operative treatment. In the given article, the authors highlight the diagnostics development stages of this disease and provide comparative characteristics of different diagnostic methods. Key words: vesicoureteral reflux, urodynamics, diagnostics, children.

The comparison of quality of the images at various stages complex dynamic nephroscintigraphy of the urinary tract received with use of various types of radiotracers. To all patients has been executed dynamic nephroscintigraphy with orthostatic sign and indirect radionuclide cystography, also the analysis of quality of images is lead by a method of expert estimations. It was established, that the best opportunities of a visual estimation of a condition of collective system of kidneys and ureters are provided with application tubular radiotraceres, and for an estimation parenchymatous phases of research — glomerular traceres. Key words: vesicoureteral reflux, secretory function of kidneys, excretory function of kidneys, dinamic scintigraphy, radionuclide cystography.
