摘要

In this prospective study the long-term impact of warm ischemia during elective nephron sparing surgery was evaluated using 99mTc-DTPA renal scintig-raphy. The main finding was that at 1 year only WIT greater than 28 minutes was associated with a significant and sustained decrease in the absolute GFR of the affected kidney without compensation by the contralateral kidney. It is important to note that accurate interpretation of radioisotope derived quantification of renal function hinges on appropriate corrections for hydration status, differential isotope uptake in different regions of the kidney (eg tumor) and body surface area.
