Abstract: Objective To retrospectively analyze the change of reversed diastolic flow in renal allografts with ultrasound and its association with clinical outcomes.Methods 17 patients with reverse diastolic flow of renal allograft were reviewed. According to the waveform morphology changes of RDF,17 cases of RDF were classified as two types: typeⅠ(total RDF changing type: continuous total RDF or non-total RDF transformed into total RDF,n=6)and type Ⅱ (non-total RDF changing type: continuous non-total RDF or total RDF transformed into non-total RDF or disappeared,n=11).Meanwhile,they were compared with clinical outcome.Results In typeⅠ, transplanted kidney resection were performed in five cases, but 10 cases in type Ⅱ were recovered. TypeⅠwas associated with lower likelihood of renal allografts survival(Fisher exact test, P=0.005).Conclusions Dynamic observation the change of RDF may help to judge the prognosis in renal allograft.TypeⅠmay predict of an unfavorable outcome in renal allograft with RDF.
