To explore the value of power Doppler ultrasound (PDU) in the evaluation of acute kidney injury(AKI).
Renal blood flow of 40 AKI cases was monitored by power Doppler ultrasound and 4-level semiquantitative PDU score method employed. All cases were divided into 3 groups by PDU score. AKI stage and duration were compared. And the co-variables of death and (continuous renal replacement therapy) CRRT days (> 3) were also analyzed by Logistic regression analysis.
A total of 40 AKI case were recruited. The 3-score group (n = 13)has lower mortality in intensive care unit and at 28 days than the 2-score group (n = 15) and the 1-score group (n = 12). The number of stage-3 AKI in the 3-score group was less than that in the 2-score and 1-score groups (n = 1, 4, 9 correspondingly, χ(2) = 16.103, degree of freedom = 4, P = 0.003). The number of persistent AKI in the 3-score group was less than that in the 2-score and 1-score groups (n = 3, 9, 10 correspondingly, P < 0.05). Age, APACHEII score and PDU score (< 3) were closely correlated with death while age, APACHEII score, level of serum creatinine and PDU score (< 3) with CRRT days (> 3) (P < 0.05).
PDU may be used to monitor renal hemodynamics in AKI patients and its score helps clinicians to evaluate the severity and prognosis of AKI.
探讨能量多普勒超声（PDU）在评估急性肾损伤（AKI）中的价值。
采用能量多普勒超声监测40例AKI患者的肾血流情况，并采用4级半定量PDU评分法。所有病例根据PDU评分分为3组。比较AKI分期及病程。并通过Logistic回归分析死亡及（持续肾脏替代治疗）CRRT天数（>3天）的相关变量。
共纳入40例AKI病例。3分组合（n = 13）在重症监护病房及28天时的死亡率低于2分组合（n = 15）和1分组合（n = 12）。3分组合中3期AKI的例数少于2分组合和1分组合（分别为1例、4例、9例，χ(2)=16.103，自由度=4，P = 0.003）。3分组合中持续性AKI的例数少于2分组合和1分组合（分别为3例、9例、10例，P < 0.05）。年龄、APACHEII评分及PDU评分（<3分）与死亡密切相关，而年龄、APACHEII评分、血清肌酐水平及PDU评分（<3分）与CRRT天数（>3天）相关（P < 0.05）。
PDU可用于监测AKI患者的肾脏血流动力学，其评分有助于临床医生评估AKI的严重程度及预后。
