To describe a case of bilateral hydronephrosis arising from a medullary thyroid carcinoma that had metastasized to both ureters.
METHODS/RESULTS: A case of bilateral hydronephrosis in an asthmatic 54-year-old female patient who consulted for recurrent bilateral nephric colic is described. The patient presented with severe impairment of renal function. Patient evaluation with imaging techniques could not identify the cause of the hydronephrosis. Bilateral ureteral catheterization improved renal function. The patient died from an episode of bronchospasm. Autopsy revealed a medullary carcinoma of the thyroid that had metastasized to several organs, including both ureters, causing hydronephrosis.
In a patient presenting with bilateral hydronephrosis without a diagnosis of a primary tumor, it is difficult to suspect an underlying metastasis to the ureter. The imaging techniques are unable to detect small metastatic lesions.
描述一例因甲状腺髓样癌转移至双侧输尿管而导致双侧肾积水的病例。
方法/结果：描述了一例54岁哮喘女性患者出现双侧肾积水的病例，该患者因复发性双侧肾绞痛前来就诊。患者肾功能严重受损。通过影像学技术对患者进行评估未能确定肾积水的原因。双侧输尿管插管改善了肾功能。患者死于一次支气管痉挛发作。尸检显示甲状腺髓样癌已转移至包括双侧输尿管在内的多个器官，导致肾积水。
对于出现双侧肾积水且未诊断出原发肿瘤的患者，很难怀疑输尿管存在潜在转移。影像学技术无法检测到小的转移病灶。
