USG finding in chronic renal disease may be: March 2009
**Core Concept**
Chronic renal disease (CRD) involves progressive renal fibrosis and loss of nephrons, leading to impaired kidney function. Ultrasonography (USG) is a valuable tool for assessing kidney morphology and detecting changes associated with CRD.
**Why the Correct Answer is Right**
In CRD, the kidneys undergo hypertrophy and dilation of the renal pelvis and calyces, resulting in a dilated appearance on USG. This is due to the increased pressure and fluid accumulation within the renal parenchyma. The increased echogenicity of the renal cortex is also a characteristic feature, which can be attributed to the deposition of fibrotic tissue and chronic inflammation.
**Why Each Wrong Option is Incorrect**
**Option A:** This choice may be a distractor, but it does not specifically relate to the characteristic USG findings in CRD.
**Option B:** While hydronephrosis can be seen in obstructive uropathy, it is not a specific finding in CRD.
**Option C:** This option may seem plausible, but it is not a direct consequence of CRD.
**Clinical Pearl / High-Yield Fact**
A key USG finding in CRD is the increased echogenicity of the renal cortex, which can be remembered as "bright" or "hyped" kidneys.
**Correct Answer: E. Echogenic kidneys with dilated pelvicalyceal system.**
