Evaluation of Renal Function before and/or after Operation Using 99mTc-DTPA Renal Scan / 대한비뇨기과학회지

ABSTRACT

Radioactive chelate such as 99mTechnetium-diethylene triaminepentaacetic acid (99mTc-DTPA) is an excellent renal imaging agent which is not metabolized and is excreted exclusively in the urine by glomerular filtration. In addition to defining the gross structure and function of the collecting system, the 99mTc-DTPA dynamic renal scan permits evaluation of early renal perfusion, regional glomerular function and gross renal structure. Twenty cases were studied with 99mTc-DTPA renal scan before and/or after urological surgery in order to evaluate their renal function. Of 20 cases, 5 cases were described precisely. The 99mTc-DTPA dynamic renal scan is a sensitive examination for determining the surgical approach method and predicting renal salvageability. It is also helpful as a follow-up method of postoperative recovery of renal function.
