【 摘 要 】

Renal papylar necrosis is rare disease. It is diagnosed by intravenous urography. Radio-logical presentation is patognomonical: necrotis focus of the papila, on the urogram is visualised as a punctiformne, blot spot of the iodine contrast, or the depots of the iodine contrast are spread from the edge of fornix to the renal medulla as a ribbon-like or needle-shaped formations, apear-ing in a late phase of illness like a crebs legs or feeler, sometimes convergning in the oreol or in ring-shaped formation, while necrotic sequestar is resorbed formating the cavity filled by iodine contrast, which has trigonal shape with the lateral basis, or necrotican sequestar can be removed with the channel system obstruction, presenting with the picture of ureterohydronephrosis, caused by the organic concrement. In the late stadium of the desease necrotic cavity can present with calcified wall and it can be diagnoses also at the native radiogram of the urotract.
