123I-hippuranによるrenoscintigraphyの泌尿器科領域における有用性について

Abstract

Dynamic renoscintigraphy using [123]I-hippuran was performed in a patient with left hydronephrosis due to a left ureter stone with a gamma camera (Sigma 410 S) and a data processing system (VIP 460), The renoscintigraphy was compared with IVU, DIU and renal angiography, The results were as follows: From the RI angiogram and perfusion curve during the early phase (up to 72 seconds) of renoscintigraphy using [123]I-OIH, the distribution of the renal vessels and renal blood flow could be recognized, The individual renal function and disturbance of the upper urinary tract could be evaluated from the dynamic renal images and renogram produced by renoscintigraphy. In conclusion, it is suggested that renoscintigraphy using [123]I-OIH is a very effective diagnostic method in practical urology.
