To present a case of urothelial tumor inside a simple ureterocele with a coexisting contralateral tumor that caused bilateral obstructive uropathy.
Follow-up evaluation of a 74-year-old male patient with superficial tumor of the urinary bladder diagnosed 4 years earlier, revealed renal failure and bilateral obstructive uropathy. The complementary tests showed a simple left ureterocele containing a lesion suggestive of a tumor and a right ureteral tumor.
After biopsy confirmed coexisting urothelial disease at 3 levels (intraureterocele, contralateral ureter and in situ carcinoma of the bladder), the patient was submitted to cystoprostatectomy, nephroureterectomy and en bloc segmental ureterectomy.
Multicentric synchronous urothelial tumors warrant a close and long follow-up of the entire urinary tract. Among the possible sites of presentation, few cases of tumors inside a ureterocele have been reported. The case described herein, with this uncommon site of presentation, is an example of panurothelial disease.
报告一例单纯输尿管囊肿内发生尿路上皮肿瘤并伴有对侧肿瘤，导致双侧梗阻性尿路病的病例。
对一名74岁男性患者进行随访评估，该患者4年前被诊断为膀胱浅表肿瘤，此次评估发现肾衰竭和双侧梗阻性尿路病。辅助检查显示左侧单纯输尿管囊肿内有一个提示肿瘤的病变，右侧输尿管有肿瘤。
活检证实存在3个层面的并存尿路上皮病变（输尿管囊肿内、对侧输尿管和膀胱原位癌）后，该患者接受了膀胱前列腺切除术、肾输尿管切除术和整块节段性输尿管切除术。
多中心同步尿路上皮肿瘤需要对整个尿路进行密切且长期的随访。在可能出现肿瘤的部位中，输尿管囊肿内发生肿瘤的病例报道较少。本文所述病例具有这种不常见的肿瘤发生部位，是全尿路上皮疾病的一个实例。
