Question

A patient presented with abdominal pain and sterile pyuria, and the x-ray showed the following features. What is the likely diagnosis?

• A. Putty kidney
• B. Nephrocalcinosis
• C. Staghorn calculus
• D. Psoas calcification

Answer 1

The Correct Option is A

The patient presented with abdominal pain and sterile pyuria, which are key clinical symptoms. Analyzing the given options and the features described in the patient's condition:

• Putty kidney: This condition is characterized by the calcification and atrophy of the renal parenchyma, often associated with chronic infections like tuberculosis of the kidney, leading to sterile pyuria and calcified appearance on x-ray.
• Nephrocalcinosis: Involves calcium deposits in the kidney parenchyma, often linked with metabolic disorders such as hyperparathyroidism or renal tubular acidosis.
• Staghorn calculus: Indicates large kidney stones filling the renal pelvis, visible on x-ray but typically associated with non-sterile pyuria due to infection.
• Psoas calcification: Relates to calcification within the psoas muscle, unrelated to kidney pathology and would not cause sterile pyuria.

Given the x-ray findings and the presence of sterile pyuria, the most likely diagnosis is Putty kidney, which aligns with the symptoms of chronic renal tuberculosis.
