So far diagnosis and follow-up of vesico-uretero-renal reflux (VUR) is primarily based on radiological voiding studies. However this is accompanied by significant gonadal radiation doses. The goal of this study was to compare the diagnostic accuracy of real time sonography, following CO2 instillation into the bladder with that of conventional radiography in the diagnosis of VUR in children. By means of sonography 13 out of the 16 grade III, and all 16 grade IV and V VUR were seen. 4 out of 7 grade II VUR could be demonstrated. No grade I reflux has been diagnosed. In conclusion, sonography reflux study is a sensitive and specific screening and follow up procedure for VUR. At present 75 per cent of all VUR's can be diagnosed by sonography alone.
迄今为止，膀胱输尿管肾反流（VUR）的诊断及随访主要基于放射学排尿研究。然而，这会伴随着较高的性腺辐射剂量。本研究的目的是比较在膀胱注入二氧化碳后实时超声检查与传统放射成像对儿童VUR诊断的准确性。通过超声检查，16例III级反流中的13例、所有16例IV级和V级反流均被发现。7例II级反流中有4例得以证实。未诊断出I级反流。总之，超声反流检查是一种用于VUR的敏感且特异的筛查及随访方法。目前，所有VUR中的75%仅通过超声检查即可诊断。
