Correlation of Various Ultrasonographic Renal Parameters With Serum Creatinine Level In Patients of Chronic Kidney Disease

Abstract

Objective: To determine the correlation of renal ultrasonographic parameters with serum creatinine levels in patients with chronic kidney disease. Study Design: Cross-sectional study. Place and Duration of Study: Armed Forces Institute of Radiology and Imaging, Rawalpindi Pakistan, from Sep 2020 to April 2021. Methodology: One hundred thirteen patients with chronic kidney disease (Stages 1 to 4) were enrolled in a cross-sectional study. Detailed history and examination were carried out. Serum creatinine levels were carried out, and findings were noted. All patients underwent renal ultrasonography evaluation, kidney parameters were assessed, findings were noted, and statistical analysis was performed. Results: The mean age of the patients was 42.96±12.71 years, the duration of Chronic kidney disease was 30.38±14.59 months, the length of the kidneys was 7.15±1.84 cm, the volume of the kidneys was 59.4±12.7 ml, the thickness of the renal cortex was 3.78±1.41 cm, thickness of renal parenchyma was 8.33±1.71 mm and serum creatinine levels were 5.36±2.63. Renal ultrasound parameters negatively correlated {for length of kidneys r=-0.187 (p=0.047), for volume r=-0.133 (p=0.161), for cortical thickness r=-0.285 (p=0.002) and parenchymal thickness r=-0.083 (0.382)} with serum creatinine level and only cortical thickness and length of kidneys had significant correlation with it. Conclusion: Ultrasound assessment is an easy and reliable tool. Measurement of cortical thickness and length of kidneys must be routinely incorporated in the ultrasonographical assessment of patients with Chronic kidney disease.
