We report a case of prolapse of a simple ureterocele presenting as perineural tumor. A 60-year-old woman presented with perineum pain and bleeding. A physical examination revealed a hard mass, 30 mm in diameter protruding from the external meatus. The computerized tomography, magnetic resonance imaging and cystography showed an uncharacterized tumor. Endoscopic examination was performed. However, just before resection the mass collapsed spontaneously and turned out to be a prolapse of ureterocele. No transurethral incision was performed. Eleven months postoperatively, the patient has not developed vesicoureteral reflux or urinary tract infection. Physicians should consider prolapse of a simple ureterocele in the differential diagnosis of the female meatal tumor.
我们报告一例表现为神经周肿瘤的单纯输尿管囊肿脱垂病例。一名60岁女性因会阴部疼痛和出血就诊。体格检查发现一个直径30毫米的硬块从尿道口突出。计算机断层扫描、磁共振成像和膀胱造影显示为一个未定性的肿瘤。进行了内镜检查。然而，就在切除前，肿块自行塌陷，结果是输尿管囊肿脱垂。未进行经尿道切开术。术后11个月，患者未出现膀胱输尿管反流或尿路感染。医生在鉴别诊断女性尿道口肿瘤时应考虑单纯输尿管囊肿脱垂。
