Nephrocalcinosis is characterized by deposits of what in the renal tubules?

• A. Uric acid
• B. Calcium phosphate
• C. Cholesterol
• D. Sodium chloride

Answer: (B)

Nephrocalcinosis refers to the condition where there is an excessive accumulation of calcium in the kidney tissue, specifically within the renal tubules. The primary component responsible for this condition is calcium phosphate, which forms deposits that can interfere with renal function. This calcium buildup can occur as a result of various metabolic disorders, hyperparathyroidism, or conditions that cause altered calcium metabolism. In this context, recognizing calcium phosphate as the correct answer is crucial for understanding the pathology associated with nephrocalcinosis and its implications for kidney health. The other substances listed, such as uric acid, cholesterol, and sodium chloride, do not form the characteristic deposits seen in nephrocalcinosis and relate to different medical conditions affecting the kidneys. Understanding this highlights the specificity of calcium phosphate in nephrocalcinosis and its significance in renal pathology.
