Abstract: Considering
the fact that grey scale ultrasonography findings in patients with chronic
medical diseases are non specific, this study was conducted to evaluate the
relationship between RI of arterial Doppler wave form and degree of renal
parenchymal damage as measured clinically by serum creatinine level. Hung
et al., 2011 stated that there is significant correlation between RI
level and serum creatinine value and so RI may serve as an indication for
predicting renal graft function after renal transplantation. Bommart et
al., 2010concluded his study by the fact that there is good correlation
between RI measured by Doppler ultrasound and kidney function and histology. Material
and Methods: The study included 70 patients with chronic renal
parenchymal medical diseases, grey scale ultrasonography was done for all cases
to assest morphological renal changes include, kidney measurements and grade of
renal echogenicity. Renal resistive index was measured by color Doppler
sonography for 10 interlobar arteries, (5 interlobar arteries for each kidney).
The ultrasonographic findings were correlated with serum creatinine levels for
these patients. Renal biopsy reports, for 30 patients were within their files. Results: We
proved that RIs were normal in non echogenic kidneys and were high in echogenic
kidneys. The second fact that with increasing in RI levels, there was increase
in serum creatinine levels. Patients with RI of (0.6) has normal serum
creatinine level 1.4. Patients of average RI of 0.74 their serum creatinine
levels were reached up to (1.9). Patients of grade 111 echogenicity recorded
high RIs ranged from 0.97 up to 1.9. Serum creatinine levels in these cases
reached 4mg /dl and more.The third important observation was that during and
after medical treatment, there was progressive lowering in RIs accompanying by
decreasing in serum creatinine levels.Conclusion: The study suggests
that Doppler sonography may be helpful in evaluation of renal function status
in patients of medical renal diseases with same sensitivity as serum creatinine
RI.in addition can delineate prognosis and guide therapy over a long term
follow up in patients with chronic renal diseases.
