Frusemide Renography

Renal Imaging

“…Diuresis-augmented renography was first described by Radó et al (1967). In the subsequent years, the method was developed as a simple technique to differentiate between obstructive and non-obstructive dilated upper urinary tracts (O'Reilly et al 1978;Britton et al 1979).…”

Advances in radionuclide evaluation of urinary tract obstruction

“…The introduction of the diuretic renogram in 1978 [28][29][30] was based on an assumption that the radionuclide retained in a dilated nonobstructed collecting system, when challenged with an increased urine flow, will be washed out. Administration of a diuretic to a dilated obstructed system will result in retention of the radio- tracer proximal to the site of obstruction [31] (Fig.…”
