Urethral leiomyomas in women arise from the smooth muscle of the urethra and are rare, benign urethral tumors seen primarily in women. We present three cases of urethral leiomyomas identified over a 30-year period at our institution. A 45-year old woman presented with a 1 year history of frequency, nocturia, and hesitancy and was found to have both a 2-cm proximal urethral and a 3-cm posterior bladder leiomyoma. She developed stress urinary incontinence postoperatively and was treated with a Burch colposuspension. A 33-year old woman with hematuria was found to have both a 3-cm urethral and a 3-cm paraurethral leiomyoma at the bladder neck. A 21-year old without urinary complaints was found to have a 3-cm leiomyoma at the urethral meatus. Urethral leiomyomas must be differentiated from paraurethral leiomyomas, which are often asymptomatic and may be removed without disrupting the urethral mucosa or smooth muscle. The removal of urethral myomas may be complicated by the development stress urinary incontinence or urethral stricture.
女性尿道平滑肌瘤起源于尿道平滑肌，是一种罕见的良性尿道肿瘤，主要见于女性。我们报告了在我院30年期间确诊的3例尿道平滑肌瘤病例。一名45岁女性有1年尿频、夜尿和排尿犹豫病史，检查发现有一个2厘米的近端尿道平滑肌瘤和一个3厘米的膀胱后壁平滑肌瘤。她术后出现压力性尿失禁，接受了Burch阴道悬吊术治疗。一名33岁血尿女性被发现膀胱颈处有一个3厘米的尿道平滑肌瘤和一个3厘米的尿道旁平滑肌瘤。一名21岁无泌尿系统症状的女性被发现尿道口有一个3厘米的平滑肌瘤。尿道平滑肌瘤必须与尿道旁平滑肌瘤相鉴别，后者通常无症状，切除时可不破坏尿道黏膜或平滑肌。切除尿道肌瘤可能会并发压力性尿失禁或尿道狭窄。
