The radiological changes of renal papillary necrosis are independent of its etiology. If total papillary necrosis (TPN) or partial papillary necrosis (PPN) is present, radiological findings are diagnostic. Whereas, if the necrotic papillae remain in situ (NIS) none of the typical radiologic features of papillary necrosis are seen. Serial radiologic studies are useful in renal papillary necrosis. Extension of papillary or medullary cavities, shrinkage of the kidney, and calcification thereby may be noted. Radiologic changes involving the ureter and bladder are those of complications such as ureteritis or development of a transitional cell carcinoma. The latter most often appears in the renal pelvis.
肾乳头坏死的影像学改变与其病因无关。如果存在全乳头坏死(TPN)或部分乳头坏死(PPN),影像学表现具有诊断意义。然而,如果坏死乳头仍原位留存(NIS),则看不到乳头坏死的典型影像学特征。系列影像学检查对肾乳头坏死很有用。可观察到乳头或髓质腔扩大、肾脏缩小以及由此产生的钙化。涉及输尿管和膀胱的影像学改变是输尿管炎或移行细胞癌等并发症的表现。后者最常出现在肾盂。
