腎スキャンニングにかんする臨床的検討

Abstract

Renal scanning was carried out on 337 cases either with 203Hg-Chlormerodrin (203Hg_C) or 203Hg-Salyrgan (203Hg_S). Clinical evaluation of renal scan was made on our experiences. 1) Renoscintigram 15 minutes after intravenous injection of 203Hg_S was as excellent as that obtained 1 to 2 hours after 203Hg_C administration. 2) Disappearance from the blood, urinary excretion, and the renal dosis estimated by successive scan showed that 203Hg_S has advantages of rapid transit through the body and minimal renal irradiation. 3) Renoscintigram was more or less useful for diagnosis of various conditions as follows. For renovascular hypertension, it gave no more information than IVP. Renoscintigram was quite valuable for diagnosis of localized parenchymal lesion, and screening with it should be made before retroperitoneal pneumography or arteriography. For congenital anomalies of the kidney, it was meaningful to make a definite diagnosis. It made the quantitative evaluation possib'le as to the functioning parenchyma. For nephrolithiasis, hydronephrosis, renal tuberculosis and pyelonephritis, the location of the circumscribed intraparenchymal lesion was made clear and the quantitative evaluation of the remaining parenchyma was made possible. This was quite informative in establishing the treatment, either nephrectomy or renal conservation. In renal failure, especially of obstructive origin, renoscintigram gave no more information than IVP.
