回顾分析5例腹膜后纤维化致肾积水患者的临床资料。5例术前均行静脉尿路造影(IVU)、逆行造影(RP)和CT检查。手术时将输尿管移位于腹腔内4例,另外1例行肾切除。5例随访6～24个月,肾功能均正常,肾积水明显好转。认为IVU、RP、CT或MRI是诊断腹膜后纤维化致肾积水的主要手段,将输尿管移位于腹腔内是行之有效的方法。 Retrospective analysis of 5 cases of retroperitoneal fibrosis caused hydronephrosis in patients with clinical data. Preoperative intravenous urography (IVU), retrograde angiography (RP) and CT were performed in 5 patients. During the operation, the ureter was displaced in 4 cases and the other 1 case underwent nephrectomy. 5 cases were followed up for 6 to 24 months, renal function were normal, hydronephrosis significantly improved. It is considered that IVU, RP, CT or MRI is the main method to diagnose hydronephrosis caused by retroperitoneal fibrosis. It is an effective method to translocate the ureter in the abdominal cavity.
