摘要

肾细胞癌占所有癌症的2-3%,是肾脏最常见的实性病变。在大约50%的病例中,通过影像学检查进行偶然诊断,大多数病例无症状。根治性手术治疗是治疗的基础,通过影像学技术进行随访是发现局部或全身复发的优先事项。一名六十岁男性,十年前因肾肿瘤行左侧根治性肾切除术。目前临床表现为无痛性肉眼血尿。ct尿路造影显示右侧肾盂输尿管扩张,病变占据输尿管远端三分之一,造成负填充缺损。内镜检查,病变切除,酪氨酸激酶抑制剂(索拉非尼)辅助治疗。这个临床病例强调了在肾细胞癌的转移行为和可预测的传播途径缺乏明确知识的情况下,对肾肿瘤患者进行严格随访的重要性。

Metástasis ureteral contralateral por tumor renal de células claras

Renal cell carcinoma represents 2-3% of all cancers and is the most frequent solid lesion of the kidney. Incidental diagnosis is made through imaging studies in approximately 50% of the cases and the majority are asymptomatic. Radical surgical treatment is the basis of management, and follow-up through imaging techniques is a priority for detecting local or systemic recurrence.

A 60-year-old man had a past history of left radical nephrectomy due to kidney tumor 10 years prior. His current clinical manifestation was painless gross hematuria. CT-urography showed right ureteropelvic ectasia with a lesion occupying the distal third of the ureter that caused a negative filling defect. Endoscopy examination, lesion excision, and adjuvant therapy based on tyrosine kinase inhibitor (sorafenib) were carried out.

This clinical case underlines the importance of strict follow-up in patients with renal neoplasias in the absence of clear knowledge of the metastatic behavior and predictable dissemination routes in renal cell carcinoma.
