Correlation of sonographic and color Doppler findings with urinary sediment and pathologic finidings in Unexplained renal impairment

Abstract

Citation based only on pathologic findings for the diagnosis of kidney disease is not sufficient and this method is invasive, with high cost of treatment and its own complications. No specific ultrasound findings for renal disease have yet been provided, which, based on this, reduced the differential diagnosis of diseases and provided an appropriate diagnosis. Therefore, the aim of this study was to examine the correlation of sonographic and color Doppler findings with urinary sediment and pathologic findings in unexplained renal impairment.Methods: In this study, 30 samples of patients with paranchymal kidney disease referred to Tabriz Imam Reza Hospital of Nephrology Department were included. Patients received a complete biography of demographic information, records of internal diseases, kidney disease records, and so on. Then the Doppler sonography and gray scale were taken from kidneys patients. In Doppler ultrasonography, information on parenchyma, kidney vessels, collecting system and ... was reported. Patients were treated with medication and at the earliest opportunity the patients were underwent biopsy of the kidneys. Data were analyzed by SPSS software version 22.Results: According to pathologic findings, renal disease was 69% acute and 31% chronic. Based on Gray Scale ultrasonography, there was a significant correlation between parenchyma thickness, ecognition of the cortex (qualitative), ecognition of the medulo (qualitative and quantitative), and differentiation of corticomedular (quantitative) with pathologic findings (P<0.05). Based on Gray Scale ultrasonography, no significant correlation was found between the length of the kidney, hydronephrosis, ecognition of the cortex (quantitative) and differentiation of corticomedular (qualitative) with pathological findings (P<0.05). There was a significant correlation between the RI and pathologic findings based on Doppler ultrasonography (P<0.05).
