A post-biopsy arteriovenous (AV) fistula in a renal allograft was diagnosed using color-coded Doppler sonography. Because the patient was asymptomatic, no specific treatment was initiated. 15 months after the diagnosis was established, severe hematuria with obstruction of the bladder occurred. Angiography revealed a connection of the fistula to the renal pelvis. The patient was treated successfully by transarterial embolization of the fistula. As a conclusion, we suggest periodical follow-up examinations of asymptomatic AV fistulas in renal allografts using color-coded Doppler sonography during 3-6 months. When no spontaneous regression of the fistula can be observed, embolization therapy should be performed even when the fistula is asymptomatic, in order to prevent late onset of complications.
通过彩色编码多普勒超声诊断出肾移植活检后动静脉（AV）瘘。由于患者无症状，未开始进行特殊治疗。确诊15个月后，出现严重血尿并伴有膀胱梗阻。血管造影显示瘘管与肾盂相连。通过经动脉栓塞瘘管成功治疗了该患者。总之，我们建议使用彩色编码多普勒超声对肾移植中无症状的AV瘘在3至6个月内进行定期随访检查。当观察不到瘘管自然消退时，即使瘘管无症状也应进行栓塞治疗，以防止并发症的晚期发生。
