Schwannoma is a tumor originating from neural sheath schwann cells. We report here a case of benign retroperitoneal schwannoma that caused bilateral ureterohydronephrosis. The retroperitoneal localization in the present case is unusual. The tumor was 21 x 18 x 11 cm in dimension and reached from the prostate to the umbilical level. Even though the patient had bilateral hydronephrosis, the renal function tests results were in the normal range. Complete surgical excision was achieved by anterior laparotomy. Histological and immunohistochemical studies confirmed the diagnosis. At 6 months follow-up there was no evidence of recurrence and renal function test results were normal.
神经鞘瘤是一种起源于神经鞘雪旺细胞的肿瘤。我们在此报告一例引起双侧输尿管积水性肾盂积水的良性腹膜后神经鞘瘤病例。本病例的腹膜后定位不常见。肿瘤大小为21×18×11厘米，从前列腺延伸至脐水平。尽管患者有双侧肾盂积水，但肾功能检查结果在正常范围内。通过前路剖腹术实现了完整的手术切除。组织学和免疫组织化学研究证实了诊断。随访6个月时，没有复发迹象，肾功能检查结果正常。
