Comparison of the diuretic renogram and the pressure perfusion study in children.
We evaluated 42 hydronephrotic kidneys with diuretic renography and pressure perfusion studies to diagnose or exclude the presence of obstruction. Both studies were highly accurate but a small number of false positive and false negative studies were observed with each testing modality. The advantages, disadvantages and potential sources of inaccuracy of each study are discussed, and a protocol for the evaluation of hydronephrosis incorporating both studies is proposed.
