A 70-year-old woman was admitted in the Department of Nephrology because of renal insufficiency. Six years previously, as consequence of a venous mesenteric thrombosis, she underwent an extense intestinal resection with subsequent short intestine syndrome. Five years after the surgery an increase in the creatinine concentration was observed (1.4 mg/dl). One year later, it increased up to 3.1 mg/dl and the patient was remitted to our Department. The radiological study revealed calcifications on both kidney silhouettes. In the next year, renal function worsened and the calcifications increased. Coinciding with the beginning of the chronic hemodialysis treatment she suffered a renal colic with passage of a calcium oxalate stone.
