According to a study, abnormal sonographic findings were seen in 67% of cases of CKD [10]. Due to the presence of collagen, echogenicity is increased in interstitial fibrosis and glomerulosclerosis [11], but this has never been recognized. Increase in echogenicity may also increase interstitial inflammation.
