Abstract
Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis in which the involved areas of the kidneys are destroyed and replaced by foam cells. It usually occurs in immunocompromised middle-aged females with ureteral obstruction or chronic urinary tract infection induced by the formation of renal stones. We herein report the case of a 44-year-old woman, with a history of left kidney staghorn calculi and recurrent urinary tract infections. Abdominal computed tomography showed the 'bear paw' sign, typical appearance of XGP and patient underwent a nephrectomy with uneventful post-operative course.
摘要
黄色肉芽肿性肾盂肾炎是一种罕见的慢性肾盂肾炎，受累的肾脏区域被破坏并被泡沫细胞取代。它通常发生在免疫功能低下的中年女性，伴有输尿管梗阻或由肾结石形成引起的慢性尿路感染。我们在此报告一例44岁女性病例，该患者有左肾鹿角形结石和复发性尿路感染病史。腹部计算机断层扫描显示“熊掌”征，这是黄色肉芽肿性肾盂肾炎的典型表现，患者接受了肾切除术，术后过程顺利。
