Abstract：
Xanthogranulomatous pyelonephritis (XGP) is a rare form of severe pyelonephritis. It is characterized by progressive parenchymal destruction caused by chronic urinary tract obstruction and infection, typically resulting in a non-functioning enlarged kidney. Its presentation with a psoas abscess is infrequent, and only a few cases are described in the literature. Unlike the typical presenting symptoms of XGP, our patient presented classic symptoms of lumbago. Once the diagnosis was established, antibiotics were given and a nephrectomy was performed. Unfortunately, after the surgery, the patient developed mild monoparesis on the right lower limb with decreased knee extension muscle strength and needed a walking stick for support. Nonetheless, a delayed diagnosis could have been fatal.
摘要：
黄色肉芽肿性肾盂肾炎（XGP）是一种罕见的严重肾盂肾炎。它的特点是由慢性尿路梗阻和感染引起的进行性实质破坏，通常导致无功能的肾脏增大。它很少出现腰大肌脓肿，文献中只描述了少数情况。与XGP的典型症状不同，我们的病人出现了典型的腰痛症状.一旦诊断确定，给予抗生素并进行肾切除术.不幸的是,手术后,患者右下肢出现轻度单瘫，膝关节伸展肌肉力量下降，需要手杖支撑。尽管如此，延迟诊断可能是致命的.
