OBJECTIVE: to determine the accuracy of Doppler ultrasonography (USD) for hemodialysis @entity2548 ( @entity2548 ) maturity. METHODS: we included @entity1 with no prior @entity2548 . Each @entity1 underwent two USD examinations. After initiation of hemodialysis, we followed the @entity1 during the first month of the access use and verified its adequacy to hemodialysis sessions. At statistical analysis we measured specificity, sensitivity, accuracy, ROC curve (Receiver operator characteristic) curve, TG-ROC (Two graph - receiver operator characteristic) and logistic regression. RESULTS: we included 76 @entity1 , of which 51 completed the study. They formed two groups, those who have had good adequacy for hemodialysis (45) and those who had not (6). The average flow volume (FV) and the average draining vein diameter (DVD) of each group were, respectively: 940mL/min (95% CI: 829-1052) and 325mL/min (95% CI: 140-510); and 0.48cm (95% CI: 0.45-0.52) and 0.33cm (95% CI: 0.27-0.40). The area under the ROC curve of FV and DVD were 0.926 and 0.766, respectively. CONCLUSION: the accuracy of the measured volume flow measured at the draining vein to evaluate maturation of hemodialysis @entity2548 was 85%.
