摘　　要：目的观察肾综合征出血热(HFRS)病程中各级肾动脉血流动力学变化。方法应用彩色多普勒超声诊断仪检测182例经血清学证实的HFRS患者病程中肾各级动脉血流频谱参数与100例正常人对照。结果HFRS临床各期各型肾动脉血流频谱在发热期、恢复期与正常对照组比较,差异无统计学意义(P>0.05);少尿期和移行期肾血流量减少,各级肾动脉RI,PI明显高于正常组(P<0.05),收缩期最大流速(Vmax),舒张末期最低流速(Vmin)在少尿期最低,尤以Vmin降低显著。结论HFRS临床各期各型肾血流动力学变化存在客观规律,有较高临床应用价值。[ Objective] To observe the hemodynamic changes of renal arteries in the course of Hemorrhagic Fever with Renal Syndrome （HFRS）. [ Methods] The blood spectrum parameters of renal arteries of 182 HFRS patients who were diagnosed by serology were detected with Color Doppler uhrasonography. And the data were compared with those of 100 healthy individuals. [ Results] There was no significant difference in renal arteries spectrum parameters between the healthy individuals and all the clinical types of HFRS in fever and convalescent stages （ P 〉 0. 05 ）. Renal blood flow decreased in oliguria and migratory stages, The resistant inde- xes （ RI ） and pulse indexes （ PI ） of all the levels of renal arteries were higher than the control group （ P 〈0. 05 ）. The peak systolic velocity （ Vmax ） and bottom end diastolic velocity （ Vmin ） of oliguria stage were the lowest, the Vmin decreased obviously. [ Conclusion ] The renal hemodynamics changes of all clinical types of HFRS in each stage have objective principle, and that has great clinical practice value.
