26 patients with normal renal transplants were examined by means of duplex sonography to define normal blood flow parameters. The renal blood flow pattern showed in each segment of the renal arteries a rapid upslope in systole followed by graduate downslope in the early diastole with persistent flow throughout the diastole. There was no significant difference between the main renal artery and the three different orders of intrarenal arteries. Mistakes can be made due to flow disturbance from turbulences at the anastomosis or by obtaining signals from other vessels located near the renal parenchyma. Several (at least two) arterial signals should be obtained by aligning the transducer along the axis of the transplant renal artery and renal parenchyma. Only the strongest signals should be recorded.
对26例肾移植正常的患者进行了双功超声检查，以确定正常的血流参数。肾血流模式显示，肾动脉各段在收缩期有快速上升斜率，随后在舒张早期逐渐下降，舒张期血流持续存在。肾主动脉与三级肾内动脉之间无显著差异。由于吻合口处的湍流引起的血流干扰或从肾实质附近的其他血管获取信号，可能会导致错误。应通过将换能器沿移植肾动脉和肾实质的轴线对齐来获取几个（至少两个）动脉信号。只应记录最强的信号。
