Print-outs of 131 I Hippuran scintillation camera study of child whose scintiphoto and intravenous pyelogram is seen in Fig. 25 and 24 respectively. It can be seen here that only 16% of total renal blood flow is present on right. Total renal blood flow is normal The increasing use of radionuc1ide cystography is probably due to the ready availability of 99mTc pertechnetate and the low radiation dose despite using millicurie amounts. It has been estimated that at least 100 radionuc1ide studies can be performed before an equal amount of radiation is received as encountered with a single roentgenographic study.
Five years following detection of bilateral reflux in this now 6-year-old child, total kidney function is completely normal, being 75%, and distribution of renal blood f10w between two kidneys is 51 % and 49%, respectively. This pattern did not change over 5 years patient was followed, and reflux now has spontaneously disappeared from the 0-3-min aeeumulation is shown in Fig. 22. The patient was followed eonservatively over a 5-year period with repeat seintillation eamera studies and repeat yearly eystograms whieh revealed disappearanee of reflux on the left after 2-3 years and finally, disappearanee of the reflux on the right at the end of 5 years.
A typical example of a segmental vascular lesion in the lower pole of the left kidney in a child with severe diastolic hypertension was demonstrated and as can be seen, renal histograms generated over upper and lower poles revealed the typical pattern of delayed uptake in the left lower pole (Fig. 13). 28 J.
