99mTc-DTPA注射液と調製用キット(日本メジフィジックス社製)を用いdynamic renoscintigraphyを666回(609例)におこない,実地泌尿器科領域での有用性につき検討した.1) Perfusion phaseのimageとcurveより,腎内血流動態を知りうる.2) Functional phaseのimageとcurveより,nephrogram,上部尿路の機能を知りうる.3) Perfusion curveとfunctional curveより腎機能を十分評価できる.4)本検査法は副作用もなく,被曝線量も少ないなど安全な検査法であるClinical usefulness of the renoscintigraphy using 99mTc-DTPA in practical urology was investigated for two years. 99mTc-DTPA injection and injectable preparation kit (supplied by Nihon Medi-Physics Co.) were used. The dynamic blood flow of the renal parenchyma could be detected from serial images and curves on the perfusion phase. Information of clear nephrogram and function of the upper urinary tract could be obtained from serial images and renogram. Separate and total renal function could be evaluated. This method of examination is evaluated as very safe, because no side effects were produced and radiation dose is low. This examination may be a useful tool and the first choice in practical urology.
