The aim of investigation was study to study the diagnostic value of TGF-html5-dom-document-internal-entity2-946-end1 and AngII as laboratory markers to identify the severity of damage to kidney tissue in the VUR. We observed 71 patients with varying degrees of VUR in the age from 1 year till 14 years (mean age 199,28±11,7 months), including 52 girls (73,2%). Depending on the RN according to DMSA-stsintishgrafii identified three groups: 1g-VUR without RH, 2-gr mild RN, 3 gr.-VUR with severe RH. The control group consisted only of healthy children (10 children), without a nephritic pathology in the anamnesis. The analysis of the received results has revealed the production of the substantial increase TGF – html5-dom-document-internal-entity2-946-end-1 and AngII in urine at all the patients with VUR in comparison with control group. The TGF-html5-dom-document-internal-entity2-946-end1/Cr level and Ang II in urine at a high degree of reflux-nephropatii is significantly above in comparison with mild degree reflux nephropathy, which confirms the link TGF-html5-dom-document-internal-entity2-946-end1 and AngII with the severity of sclerotic processes in tubulointerstitial tissue. Search for available biomarker of early and tubulointerstitial fibrosis shows, that AngII and TGF-html5-dom-document-internal-entity2-946-end1 can be use as a criterion for the progression of reflux nephropathy in the VUR.
