A 70-year-old man with previous history of TUR-BT presented positive urinary cytology at one year follow-up. Cystoscopy with bladder mapping was negative, and IVP revealed multiple outpouchings of the right upper ureter without hydronephrosis. Ureteroscopy failed because of an underlying stricture. Surgical excision of the strictured segment and of 2.5 cm of cranial ureter was performed. Histopathology demonstrated focal hyperplasia of the urothelium with outpouchings involving only the mucosa, compatible with the diagnosis of pseudodiverticula.
一名70岁男性，既往有经尿道膀胱肿瘤电切术（TUR-BT）史，在随访一年时尿细胞学检查呈阳性。膀胱镜检查及膀胱地图活检结果为阴性，静脉肾盂造影（IVP）显示右上输尿管有多个憩室样突出，无肾积水。由于存在潜在狭窄，输尿管镜检查失败。遂对狭窄段及上方2.5 cm的输尿管进行手术切除。组织病理学显示尿路上皮局灶性增生，憩室样突出仅累及黏膜，符合假性憩室的诊断。
