Leiomyomas are benign tumors of smooth muscle origin occurring throughout the genitourinary system. While leiomyomas in the uterus are frequently seen, urethral and paraurethral leiomyomas are extremely rare with a hand full of cases in the literature. Typically, periurethral leiomyomas can present with a mass protruding from the urethra originating from the proximal and posterior portion of the urethra. Herein, we present a new case of a paraurethral leiomyoma causing mass effect on the bladder leading to lower urinary tract symptoms (LUTS) with no gross involvement of the urethra.
平滑肌瘤是起源于平滑肌的良性肿瘤，可发生于整个泌尿生殖系统。虽然子宫平滑肌瘤很常见，但尿道及尿道旁平滑肌瘤极为罕见，文献中仅有少数病例报道。通常，尿道周围平滑肌瘤可表现为从尿道近端和后部突出的肿块。在此，我们报告一例新的尿道旁平滑肌瘤病例，该肿瘤对膀胱产生占位效应，导致下尿路症状（LUTS），但尿道未出现明显受累。
