Chronic Kidney Disease: The Daily PANCE Blueprint
A 62-year-old male with a 40-year history of poorly controlled hypertension and Type 2 diabetes presents with fatigue, peripheral edema, and nocturia. His physical exam reveals bilateral lower extremity pitting edema. Lab results show a serum creatinine level of 3.5 mg/dL and a GFR of 22 mL/min/1.73 m². Urinalysis shows proteinuria. Which of the following is the most likely initial finding on a renal ultrasound?
A. Bilateral hydronephrosis
B. Increased renal parenchymal thickness
C. Unilateral renal atrophy
D. Large, cystic kidneys
E. Small, echogenic kidneys
Answer and topic summary
The answer is E. Small, echogenic kidneys
Chronic kidney disease (CKD) is a progressive loss of renal function over months to years. In patients with long-standing hypertension and diabetes, the most common causes of CKD, the kidneys undergo a slow, irreversible fibrotic process. This leads to a gradual reduction in kidney size and increased echogenicity on ultrasound, which reflects the scarring and atrophy of the renal parenchyma. An ultrasound showing small, echogenic kidneys is the classic finding in advanced CKD, although in early disease, the kidneys may appear normal in size. Treatment focuses on managing the underlying cause (e.g., blood pressure control, glycemic control) and slowing disease progression, as well as managing complications such as electrolyte imbalances and anemia.
