Abstract: Objective: A prospective study developed to determine the relationship between the ultrasonographic parameters (kidney length, parenchymal thickness and parenchymal echogenicity obtained from both kidneys) and glomerular filtration rate in patients with Chronic Kidney Disease. Materials and methods: A cross sectional study in 50 patients referred to the department of Radiodiagnosis, Sree Mookambika Institute of Medical Science, Kulasekharam, for ultrasound abdomen with abnormal renal function tests during the period of 12 months (June 2019- June 2020) and who fulfilled the inclusion and exclusion criteria were selected. Both kidneys were evaluated by Siemens ACUSON X300 scanner using a 5.0MHZ wide frequency band, phased assay probe. The US parameters renal length, mean parenchymal thickness and parenchymal echogenicity were evaluated for both right and left kidneys. All three parameters were scored for each kidney and sum of the average scores were used to calculate ultrasonographic CKD score. The eGFR was calculated by using MDRD equation. The correlation between the eGFR and the kidney length, parenchymal thickness, parenchymal echogenicity and ultrasonographic CKD score were made out separately. Results: The mean serum creatinine was 3.9±2.2 and estimated glomerular filtration rate is 22.8±15.1. No patients with eGFR > 90 ml i.e. stage I of kidney disease was studied. The mean renal length in stage V (8.0±1.4), stage IV (8.4±1.0), stage III (9.5±1.3) and stage II (9.8±0.6). The parenchymal thickness in stage V (10.2±3.2), stage IV (10.4±1.8), stage III (13.2±2.6) and stage II (14.2±2.1). The median parenchymal echogenicity in stage V (2.5), stage IV & III (2) and stage II (1). The sonographic CKD score from 4 to 13, stage V (7.9±2.4), stage IV (8.1±1.6), stage III (6.1±1.5) and stage II (5.0±0.7). Conclusion: The ultrasonographic CKD score calculated from the USG parameters such as renal length, parenchymal thickness and parenchymal echogenicity is useful for differentiation of CKD stage 3-5 compared to CKD stage 1-2. We concluded that the ultrasonographic CKD score provide more objective data in the assessment of CKD.
