Grading Of Renal Parenchymal Disease Using Gray Scale Ultrasound

Abstract

The shape of the normal adult kidney is like a bean, retroperitoneally present between twelve thoracic and third lumbar vertebra. Ultrasound can identify increased cortical echogenicity and reduced cortical parenchymal thickness, as well as reduced renal size in CKD. Objective: To diagnose renal parenchymal disease and its grading using gray scale sonography. Methods: It was cross-sectional research undertaken at Tertiary Hospital in Lahore, Pakistan radiology department. This research took place over five months, from January 2022 to May 2022. A convenient sampling approach using previously published articles was used to obtain a sample size of 78 patients. After informed consent, patients who were assessed for renal ultrasonography at the study region, during the study period, were included. Data was entered and analyzed on SPSS version 22.0. Results: The mean age was 46.47±12.0. The frequency for males was 47(60.3%), and for females was 31(39.7%). Blood urea (mg/dl) had a mean value of 92.16±46.88, and Serum creatinine (mg/dl) in male patients had a mean value of 6.86±6.18 while in female patients had 5.50±5.36. The blood urea nitrogen of patients had a mean value of 50.16±33.70 and a glomerular filtration rate with a mean value of 81.34±23.12. The frequencies of sonographic grading of renal cortical echogenicity show patients of Grade 1 had 32(41.0%), Grade 2 28(35.9%), Grade 3 12(15.4%), and Grade 4 6(7.7%). Conclusion: Renal parenchymal disease is the most prevalent disease in elder males. Grade 1 of renal parenchymal disease is most common in patients, followed by Grade 2, Grade 3, and Grade 4.
