Urethral prolapse (UP) is a rare condition with unknown etiology. We reported on an 86-year-old woman with a normal BMI and cystocele, presented with acute urinary retention and perineal pain. A residual urine of 950 mL was measured and released by an indwelling catheter. The physical examination revealed 2 × 3 cm severely sore and purple polyp around the urethral meatus with signs of necrosis. A diagnosis of a strangulated urethral prolapse was stated.
The patient was admitted to the Department of Urology, and treated with surgical excision using the four-quadrant excisional technique. The histopathological examination revealed a non-keratinized, inflammatory squamous epithelium. At a follow-up visit, the patient remained asymptomatic and a complete anatomical resolution was achieved.
UP is an uncommon, sometimes misdiagnosed condition. The management is controversial and to date no consensus exists. This clinical picture is sufficient for diagnosis and surgical excision of the prolapsed urethral mucosa is reasonable if there are signs of strangulation.
尿道脱垂（UP）是一种病因不明的罕见病症。我们报告了一名86岁、体重指数正常且患有膀胱膨出的女性，她出现急性尿潴留和会阴疼痛。测量残余尿量为950毫升，并通过留置导尿管排出。体格检查发现尿道口周围有一个2×3厘米、严重疼痛且呈紫色的息肉，伴有坏死迹象。诊断为绞窄性尿道脱垂。
患者入住泌尿外科，采用四象限切除技术进行手术切除治疗。组织病理学检查显示为非角化性炎性鳞状上皮。在随访中，患者无症状，解剖结构完全恢复正常。
尿道脱垂是一种罕见的、有时会被误诊的病症。其治疗存在争议，迄今为止尚未达成共识。这种临床表现足以确诊，若有绞窄迹象，对脱垂的尿道黏膜进行手术切除是合理的。
