[Comparison of the renal ultrasound-furosemide test with the isotope nephrogram. Possible clue to the retention phenomenon?].
In 23 patients with essential hypertension renographic and sonographic examination of the kidneys was compared. No correlation could be observed for functional parameters and urinary excretion between the two different methods. Correlations have only been detected between renographic retentions and furosemide-conditioned swelling of the kidneys in sonography: patients with severe retention showed a statistically significant stronger response to furosemide. The increased retention in the renal pelvis could be responsible for alterations in sonographic findings. This study provides new data on the mechanisms of retention, whereby retention in the renal pelvis in some patients seems to be most probably caused by nephrosclerosis.
