[Radiologic and gammagraphic findings in a case of pyonephrosis. Anatomopathologic correlation].

Objective: To describe a case of pyonephrosis in a child with special reference to the importance of scintigraphy in its evaluation.

Methods: We studied the correlation of the findings of conventional radiology (abdominal x-ray), ultrasound, abdominal CT, scintigraphy and anatomopathology (left kidney) in a 5-year-old boy with a history of renal lithiasis that was seen at our pediatric emergency services. The patient's clinical course and the scinscan findings using two tracers (Tc-99m DMSA, Ga-67 citrate) showed a severely compromised left renal function.
