The Study on the Effectiveness of [68Ga]Ga-HBED-CC-DiAsp PET/CT in Calculating GFR and Predicting Residual Renal Function After Partial Nephrectomy

Brief summary (registry, in English)

In subjects with different levels of renal function and no history of renal tumors, GFR is measured using \[68Ga\]Ga-HBED-CC-DiAsp PET/CT, the Gates method, and the 99mTc-DTPA dual plasma method. The consistency between the three methods is analyzed using intra-class correlation coefficient (ICC), concordance correlation coefficient (CCC), and Bland-Altman analysis. In patients scheduled for partial nephrectomy due to renal tumors, GFR is measured using the three methods within 2 weeks before surgery and 4±1 weeks post-surgery. The percentage of postoperative residual renal function (postoperative GFR/preoperative GFR × 100%, hereafter referred to as RRF%) is calculated for each method. By comparing and overlaying preoperative and postoperative PET/CT images, the resected renal area can be delineated on the preoperative PET/CT image. Based on the preoperative PET/CT and the delineated surgical area, a predictive value for postoperative GFR is calculated to obtain the predicted RRF%. A consistency analysis is then performed between the predicted RRF% and the actual RRF% measured by the three methods, using ICC, CCC, and Bland-Altman analysis to evaluate the efficacy of \[68Ga\]Ga-HBED-CC-DiAsp PET/CT in predicting residual renal function after partial nephrectomy.
