Sarcomatoid urothelial carcinoma (SUC), a rare tumor of the urinary tract epithelium, exhibits a high degree of malignancy and therefore a poor prognosis. Due to the absence of specific clinical presentations and imaging findings, SUC of the renal pelvis masquerades as a renal abscess is frequently under-recognized or misdiagnosed as benign inflammatory disease, resulting in delayed or erroneous treatment. Here, we report a patient with SUC of the renal pelvis who presented with a renal abscess. Repeated anti-inflammatory treatment was ineffective. Unexpectedly, cancerous cells were detected in subsequent exfoliative cytology of nephrostomy drainage fluid. In accordance with this, radical surgery and postoperative chemotherapy were conducted. Fortunately, neither recurrence nor metastasis occurred during a one-year follow-up.
肉瘤样尿路上皮癌（SUC）是一种罕见的泌尿道上皮肿瘤，具有高度恶性，因此预后较差。由于缺乏特异性临床表现和影像学表现，肾盂SUC伪装成肾脓肿时常常未被充分认识或被误诊为良性炎症性疾病，导致治疗延迟或错误。在此，我们报告一例表现为肾脓肿的肾盂SUC患者。反复抗炎治疗无效。出乎意料的是，在随后的肾造瘘引流液脱落细胞学检查中发现了癌细胞。据此，进行了根治性手术和术后化疗。幸运的是，在一年的随访期间未发生复发或转移。
