A 70-year-old man, complaining of percutaneous fistula with jelly-like yellow mucus in the right kidney for a month, was admitted to our department. From computed tomography, stones and severe hydronephrosis but no suspicious mass was found in right kidney. Nephrectomy of right kidney was performed and pathological examination revealed a villous adenoma in the renal pelvis with moderate to severe atypical hyperplasia of glandular epithelium. Primary villous adenoma in renal pelvis is rare and believed to be related to chronic irritation of stone and inflammation. Mostly nephrectomy was performed before diagnosis was made.
一名70岁男性，因右肾经皮瘘管伴黄色胶冻样黏液1个月而入住我科。计算机断层扫描显示右肾有结石和严重肾积水，但未发现可疑肿块。行右肾切除术，病理检查显示肾盂绒毛状腺瘤，腺上皮中度至重度非典型增生。肾盂原发性绒毛状腺瘤罕见，被认为与结石和炎症的慢性刺激有关。大多数情况下在确诊前就进行了肾切除术。
