[Correction of divided renal clearance studies--a comparison of renal depths (author's transl)].
Differences in renal depth can be determined by ultrasound investigation and profile measurements of a digitalised lateral renal scintigram. Both methods are simple and equally suitable for determining renal depth. Amongst 42 patients there were three in whom there were considerable differences in renal depth in the supine position, and seven patients with a similar difference when they were sitting upright. A correction for renal depth resulted in a reduction in the error obtained on divided renal clearance studies. Measurements on a renal phantom designed to obtain the half-value layer of 131I and 99mTc provide quantitative data for the correction. The correction is less easily carried out when renal depth differences occur in the sitting position than when the patient was lying down. Determination of renal depth when the patient is lying down can be confined to individual cases which can be selected from the total clinical material.
