This paper reports the Duplex Doppler blood flow spectrum of both renal arteries and abdominal aorta in 14 cases suffered from polycystic kidney (PCK) and 16 normal individuals to find the renal function status in relation to the peak flow velocity(PFV), pulsatility index(Pl) and blood flow volume (Q). The results showed that the control, PCK with creatinine<2mg% and>g%, PFV and Q had a statisticaly significant difference (P<0.001). It realized that their PFV and Q already...

This paper reports the Duplex Doppler blood flow spectrum of both renal arteries and abdominal aorta in 14 cases suffered from polycystic kidney (PCK) and 16 normal individuals to find the renal function status in relation to the peak flow velocity(PFV), pulsatility index(Pl) and blood flow volume (Q). The results showed that the control, PCK with creatinine<2mg% and>g%, PFV and Q had a statisticaly significant difference (P<0.001). It realized that their PFV and Q already had been involved before renal dysfunction appeared clinically, while creatinine>6mg%. PI might become abnormal. PFV and Q of abdominal aorta of all the polycystic kidney patients except two showed marked decreased as compared with the normal control (P<0.005). Such suggested that decreased PFV and elevation of blood pressure both resulted from the systemic reaction in early stage. Mechanism of Doppler blood flow ultrasonic spectrum of the polycystic kidney was discussed.

本文报告用脉冲超声多普勒检测了16例正常人和11例多囊肾病人的双侧肾动脉和腹主动脉的血流频谱,分析了肾动脉的峰值血流速度(PFV)、阻力指数(PI)及血流量(Q)与肾功能的关系。发现正常人,多囊肾病人的血清肌酐浓度(Cr)<2mg%者和>6mg%者之间的PFV及Q有非常显著的差异(P<0.001),而PI仅当Cr>6mg%时才发生异常。说明多囊肾病人在肾功能受累之前肾动脉的PFV和Q已有异常改变;仅当肾功能受损时才出现PI的变化。 多囊肾病人腹主动脉的PFV,在肾功能受损之前较正常人明显下降(P<0.005)。这些病人除2例外,均有血压升高,说明他们的腹主动脉的PFV下降和血压升高一样都是全身性反应.本文还讨论了多囊肾血流多普勒频谱变化的机制。
