Doppler ultrasound in pelviureteric junction obstruction in infants and children.
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.
