Retrocaval ureter is a rare congenital anomaly with the ureter passage posterior to the inferior vena cava. Surgical repair is suggested for patients with significant functional obstruction. However, there is little literature to suggest the management of asymptomatic patients.
Case 1 patient is a 29 year-old Indonesian man and case 2 patient is a 41 year-old Malay man. Both patients were asymptomatic and well.
This report is the short follow-up, therefore making it impossible to elucidate the natural history of uncorrected retrocaval ureters.
At 8 month and 6 month respectively, they remained well without symptoms. Our report suggests that immediate surgical repair is not always needed. Longer follow-up with larger patient population is needed to formally elucidate the natural history of this uncommon condition.
腔静脉后输尿管是一种罕见的先天性异常,输尿管走行于下腔静脉后方。对于有明显功能性梗阻的患者建议进行手术修复。然而,几乎没有文献提及无症状患者的处理方法。
病例1患者为一名29岁的印度尼西亚男性,病例2患者为一名41岁的马来西亚男性。两名患者均无症状且情况良好。
本报告随访时间短,因此无法阐明未经矫正的腔静脉后输尿管的自然病程。
分别在8个月和6个月时,他们仍情况良好且无症状。我们的报告表明并非总是需要立即进行手术修复。需要对更多患者进行更长时间的随访,以正式阐明这种罕见病症的自然病程。
