Acute radiorenography during attacks of renal colic.
Acute radiorenography was compared to emergency excretory urography to evaluate its diagnostic accuracy in 22 patients with clinical signs of renal colic, including erythrocytes in the urinalysis. All 16 patients with delayed excretion and/or dilated renal pelves on excretory urography had delayed excretion of radioactivity on renography. Furthermore, 6 patients with reduced renal function judged by renography had marked or slight delay in excretion on excretory urography. Small stones not causing stasis were found on excretory urography in 2 patients with normal renograms. It is concluded that acute radiorenography is simple, rapid and safe, and identifies accurately patients with abnormal renal function during attacks of colic, with less risks than excretory urography of causing renal damage or aggravating the pain of renal colic.
