Abstract
The lack of specificity of the conventional sonography and the limited morphologic response of the kidney to various pathological insults, reduced its effectiveness in the field of parenchymal renal diseases. Consequently, duplex Doppler has been newly introduced as a promising tool to provide physiologic information through the reflection of changes in the intra-renal vascular resistance on the Doppler indices. The purpose of our study was to evaluate the role of grey scale and duplex Doppler ultrasonography in the assessment of parenchymal renal diseases. The resulting data were compared to those of the renal biopsies as well as to the serum creatinine level as an indicator of the degree of renal dysfunction.This study was conducted on 50 patients; 23 males and 27 females with age ranging from 4-62 years. Ultrasonographic examination (grey scale and duplex Doppler) for all patients was carried out before the renal biopsy.Patients in this study were represented in 19 different disease types according to the biopsy results. Grey scale sonographic data showed that the relative cortical echogenicity was normal in 50% of our patients and showed no dependency with the specific type of disease. However, as agreed by most investigators, statistically significant dependency was found with the presence of certain histopathological findings as global sclerosis, interstitial fibrosis.
