Medullary Sponge Kidney and Medullary Nephrocalcinosis

摘要

A 40-year-old female patient came to an outpatient sonography department for a follow-up scan of calculi in the right ureter that were originally found at another medical facility. The study was ordered to see if the stones caused hydronephrosis within the right kidney. Bilaterally, echogenic renal medullae were visualized, indicating a case of medullary sponge kidney and medullary nephrocalcinosis.
