[Isotope diagnostic findigs in nephroptoses].

Radiorenography, serial scans and clearance determinations using 131-I-Iodohippurate and 51-CPr-EDTA were performed on a total of 106 patients with unilateral nephroptosis. In 45 of them with pathological findings in the upright position the examination was repeated in the prone position. 19 patients underwent nephropexy and were reexamined 2 to 6 weeks there after. The results suggest that the combination of different radioisotope methods provides a valuable and sensitive means to detect posture-dependent impairment of kidney and urinary tract function and yields an additional objective basis for the selection of patients for nephropexy.
