Comparing Diagnostic Value of Renal Parenchymal Resistive Index And Cortical Echogenicity in Chronic Kidney Disease Patients

Abstract

Background: Chronic kidney disease (CKD) is a clinically impaired kidney degradation syndrome, which commonly is diagnosed based on glomerulus filtration rate (GFR). Renal parenchymal resistive index and the renal cortex echogenicity are ultrasound parameters that have been reported correlate with GFR values. This study aims to determine the sensitivity, specificity, positive predictive value, and negative predictive value between renal intra-parenchymal resistive index and renal cortical echogenicitybased on GFR in CKD patients.Materials and Methods: This study is a cross sectional design. A renal ultrasound examination was performed to forty one CKD patients to assess the resistive index of the renal intra-parenchymal artery and the echogenicityof the renal cortex. The creatinine serum levels were obtained from the patients, as the gold standard of CKD diagnosis. Statistical data processing uses diagnostic test and Inter class Correlation Coefficients (ICC).Results: The sensitivity, specificity, positive predictive value, and negative predictive value of renal intraparenchymal resistive indexes were 23%, 79%, 33%, and 69% respectively. Sensitivity, specificity, positive predictive value, and negative predictive value between renal cortex echogenicity were 23%, 96%, 75%, and 73% respectively. The ICC analysisreported a Single Rater value of 0.1538 and Average of Raters 0.3528.Conclusion: Renal intra-parenchymal resistive artery was more specific than renal cortex echogenicity for diagnosing patients with chronic kidney disease.International Journal of Human and Health Sciences Vol. 04 No. 03 July’20 Page : 194-199

Rare Clinical Cases of Renal Artery Thrombosis

“…8 The main causes of renal artery thrombosis may be trauma, 9,10 kidney transplantation, 11,12 thrombophilia, 13 systemic lupus erythematosus, and antiphospholipid syndrome. [14][15][16] Also,renal artery atherosclerosis, 17 polycythemia, iatrogenic damage to the aorta and renal vessels, 18 the use of hormonal oral contraceptives, 19 drug use, 20 including intravenous, 21 bacterial endocarditis, 22 caused by spontaneous injury of segmental renal vessels, 23 diabetes and arterial hypertension, obesity and atrial fibrillation. 3,4 Only some studies are large enough to represent the most likely causes of renal artery thrombosis, such as diabetes (11-14.9%), hypertension (43.8-44%), obesity (33%), atrial fibrillation (28-30%), peripheral vascular disease (17%), prior thrombosis (11%), estrogen-progesterone therapy (11%) and smoking (17%).…”

“…29 However, thrombolytic therapy is limited in time (90-180 minutes from the thrombosis development), 30 while most cases are diagnosed within the first 24 hours. 22 Stenting after thrombectomy is less common. 31 It is advisable to choose treatment tactics based on the degree of thrombosis.…”
