Two patients with ileal loop urinary diversions, studied with real-time and Doppler sonography ("duplex sonography") of the kidneys, were shown to have dilated intrarenal collecting systems. Resistive index measurements calculated from the Doppler signal correctly identified obstructive dilatation in 1 case and nonobstructive dilatation in the other.
两名接受回肠袢代膀胱术的患者接受了肾脏实时和多普勒超声检查（“复式超声检查”），结果显示其肾内集合系统扩张。根据多普勒信号计算得出的阻力指数测量值正确识别出1例为梗阻性扩张，另1例为非梗阻性扩张。
