Abstract

Malignant tumors of the smooth muscle of the ureter are extremely rare, with ~13 cases of leiomyosarcoma of the ureter being reported to date. A 59-year-old Caucasian woman presented to 'Umberto I' Hospital (Nocera Inferiore, Italy) with acute abdominal pain, predominantly in the right lumbar fossa. The patient exhibited a functional single kidney, due to left renal atrophy for a long-standing stenosis of the pyelo-ureteric joint. With the exception of this condition and hypertension (under medical therapy), the patient was in excellent clinical condition. Furthermore, the patient was not a smoker. Computed tomography indicated a stricture with a peri-ureteral soft tissue mass of 45×52 mm at the middle third of the ureter at the level of common iliac vessels. Laparoscopic excision with safety margin and a right tension free end-to-end anastomosis between the two stumps of the ureter was performed. The diagnosis of leiomyosarcoma of the right ureter was made by pathological examination. Although leiomyosarcoma is rarely noted in the urinary tract, it should be considered in the differential diagnosis of ureteral stricture disease and retroperitoneal tumors.

输尿管原发性平滑肌肉瘤1例。
输尿管平滑肌恶性肿瘤极为罕见,迄今为止报道的输尿管平滑肌肉瘤约13例。一名59岁白人妇女因急性腹痛(主要在右腰窝)来到Umberto I医院(意大利Nocera Inferiore)。患者表现出单肾功能,由于长期狭窄的肾盂输尿管左肾萎缩。除此病和高血压(药物治疗)外,患者临床状况良好。此外,该患者不吸烟。计算机断层扫描显示输尿管中三分之一处髂总血管水平处输尿管周围软组织肿块45×52 mm狭窄。腹腔镜下安全边缘切除,两根输尿管残端间无张力端对端吻合。病理诊断为右输尿管平滑肌肉瘤。虽然平滑肌肉瘤很少发生在泌尿道,但在输尿管狭窄疾病和腹膜后肿瘤的鉴别诊断中应予以考虑。
