Three cases of proven PUJ (pelvi-ureteric junction) obstruction in whom duplex Doppler sonography was performed are described. In one case, there was a duplex transplant kidney with PUJ obstruction of the lower pole moiety. The resistive index of an interlobar lower pole artery was markedly elevated compared to that of an artery in the upper unobstructed moiety. In the other two cases, the resistive index of interlobar arteries of native kidneys increased significantly following intravenous frusemide simultaneous with an increase in the degree of pelvicalyceal dilatation. It is proposed that diuresis Doppler sonography may provide additional diagnostic information in patients with PUJ obstruction, and that the method warrants further evaluation.
本文描述了3例经证实的肾盂输尿管连接部（PUJ）梗阻患者，均接受了双功多普勒超声检查。其中1例为双功移植肾，下极部分存在PUJ梗阻。与上极未梗阻部分的动脉相比，下极叶间动脉的阻力指数明显升高。另外2例患者，静脉注射速尿后，患侧肾脏叶间动脉的阻力指数显著增加，同时肾盂肾盏扩张程度加重。研究表明，利尿期多普勒超声检查可为PUJ梗阻患者提供额外的诊断信息，该方法值得进一步评估。
