Six infants and seven children with known pelviureteric junction (PUJ) obstruction (11 unilateral, 2 bilateral) were assessed with Doppler ultrasound before and after diuresis. After intravenous frusemide, there was a significant increase in the resistance index in the interlobar renal arteries of the obstructed kidneys. No such change was detected in the normal kidneys. Five patients were reassessed after pyeloplasty. The Doppler indexes facilitated prediction of those cases with a satisfactory outcome after surgery. Doppler ultrasound with diuresis is useful in the assessment of PUJ obstruction in infants and children and in the postoperative follow-up.
对6例婴儿和7例已知肾盂输尿管连接部（PUJ）梗阻的儿童（11例单侧，2例双侧）在利尿前后进行了多普勒超声评估。静脉注射速尿后，梗阻侧肾脏叶间肾动脉的阻力指数显著增加。正常肾脏未检测到此类变化。5例患者在肾盂成形术后进行了重新评估。多普勒指数有助于预测术后预后良好的病例。利尿状态下的多普勒超声有助于评估婴幼儿PUJ梗阻情况及术后随访。
