Abstract
In 47 patients the value of kidney depth measurements for the correction of unilateral 131-I-hippuran clearances was studied using ultrasonography. The accuracy of this method was found to be superior to that of the lateral scintigram. In cases with normal cranio-caudal position or slight unilateral caudal dystopia the maximum difference in kidney depth was 1.25 cm and a maximum correction of the unilateral clearance in 2.8% was necessary. Kidneys with unilateral caudal dystopia differed up to 6 cm in depth, leading to a correction by 12%. Our findings indicate that a correction for kidney depth is necessary if one kidney shows significant caudal dystopia and slight dystopia in the supine position. In patients with nephroptosis position-dependent alterations of unilateral perfusion can only be evaluated by correcting for kidney depth.
