彩超对肾囊肿患者肾动脉血流的研究

目的：探讨肾囊肿患者肾动脉血流的改变，为肾囊肿的诊断与鉴别诊断提供一条新途径。方法：对９８例肾囊肿患者和８７例正常人肾动脉进行研究。结果：１多囊肾患者组肾动脉平均峰值流速高于对照组，二者比较有显著性差异（Ｐ〈０．０１）；血管阻力指数低于正常对照组（Ｐ〈０．０１）；２、单纯性肾囊肿患者组肾动脉平均峰值流速高于对照组（Ｐ〈０．０１），血管阻力指数高于正常对照组（Ｐ〉０．０１）；３、ＵＪＦＪＸＧＢ ＮＴ

Study of Renal Artey Blood Flow by Color Doppler Flow Imaging in Patient with Renal Cyst

Objective:To study the blood changes of renal artery in patients with renal cyst Methods:Renal artery in 98 patients with renal cyst and 87 normal persons were studied Results:1 The mean peak systolic flow velocity (PSFV) of renal artery in the patients was higher than that of control the with significant difference ( P <0 01) The resistive index (RI) of blood vessel was lower than control ( P <0 01); 2 The mean PSFV and RI of renal artery in patients with simple renal eyst were higher than the control ( P <0 01); 3 There was no significant difference between the simple renal cyst and the polycyst groups in mean PSFV of renal artery ( P >0 05), the RI of simple renal cyst group was higher than that of the polycyst group ( P <0 01);4 With the enlarging of the eyst size, the PSFV and the RI of renal artery in patient with simple renal cyst increased ( P <0 01),while in patients with polycyst,the changes were not noticeable( P >0 05);5 For the patients with polycyst, the PSFV of renal artery increased with the number of renal cyst,while the RI decreased at the same situation ( P <0 01) But for the patients with simple renal cyst, the PSFV and the RI of renal artery have no significant difference ( P >0 05) Conclusions:1 The blood fiow of renal artery in patients with polycyst was higher than that of the normal;2 Spasm of renal artery may be occurred in patients with enlarged simple renal cyst
