下腔静脉后输尿管的诊断和治疗——附6例报告

Diagnosis and treatment of retrocaval ureter: a report of 6 cases

目的探讨下腔静脉后输尿管的诊断和治疗。方法对我院收治的6例下腔静脉后输尿管的临床资料进行回顾性分析。结果6例中男5例,女1例,年龄28～53岁,平均37.2岁。临床表现为泌尿系症状,无特异性。6例均行静脉尿路造影和逆行输尿管插管造影,4例行输尿管CT检查,1例采用磁共振尿路成像(MRU),术前均获明确诊断。手术方法采用输尿管切断复位输尿管端端吻合术。术后随访10个月～5年,临床症状消失,吻合口无狭窄,肾脏积水减轻。结论下腔静脉后输尿管是一种少见的输尿管发育畸形,逆行输尿管插管造影并CT检查对下腔静脉后输尿管的诊断较为准确可靠,手术方法采用输尿管切断复位输尿管端端吻合术,效果良好。

ObjectiveTo investigate the diagnosis and treatment of retrocaval ureter.MethodsThe clinical data of 6cases of retrocaval ureter were analyzed retrospectively. ResultsIn 6 patients,5 patients were male and 1 was female. Theage ranged from 28～53 years. The average age was 37.2 years. The clinical manifestations of retrocaval ureter were notspecific. Intravenous urography and retrograde ureterography were used to make the preoperative diagnosis in 6 cases. 4 caseshad been confirmed by retrograde ureterography combined with CT and 1 by MRU. All the patients were treated with opensurgery. During the follow-up of 10 months to 5 years, the therapeutic effects were satisfied.ConclusionsRetrocavalureter is a rare congenital anomaly of ureter growth. Retrograde ureterography combined with CT is accurate and reliable fordiagnosis of retrocaval uretre. Ureter- ureteral anastomosis after a incision of ureter in both sides of cavum is safe andefficient for treatment of retrocaval ureter.
