INTRODUCTION
Xanthogranulomatous pyelonephritis (XGP) is a type of chronic renal inflammation that usually occurs in immunocompromised middle-aged women with chronic urinary tract infection or ureteral obstruction induced by the formation of ureteral stones. XGP with an incomplete double ureter is extremely rare.
CASE PRESENTATION
A 76-year-old woman was referred to our department to undergo further examination for a left renal tumor that was detected by ultrasonography. Dynamic contrast computed tomography (CT) revealed an enhanced tumor in the upper renal parenchyma. Laparoscopic radical nephrectomy was performed based on a preoperative diagnosis of renal cell carcinoma. Histological sections showed the aggregation of foam cells; thus, XGP was diagnosed.
CONCLUSION
We herein report a rare case of XGP in the upper pole of the kidney, which might have been associated with an incomplete double ureter.
引言
黄色肉芽肿性肾盂肾炎（XGP）是一种慢性肾脏炎症，通常发生于患有慢性尿路感染或因输尿管结石形成导致输尿管梗阻的免疫功能低下的中年女性。伴有不完全性双输尿管的XGP极为罕见。
病例报告
一名76岁女性因超声检查发现左肾肿瘤转诊至我科进一步检查。动态对比增强计算机断层扫描（CT）显示肾上部实质有强化肿瘤。基于术前肾细胞癌诊断行腹腔镜根治性肾切除术。组织学切片显示泡沫细胞聚集，因此诊断为XGP。
结论
我们在此报告一例罕见的肾上极XGP病例，可能与不完全性双输尿管有关。
