Computed Tomography Renal Volumetry Better Predicts Postoperative Donor Renal Function in Live Kidney Donor Transplantation than Renal Scintigraphy: A Comparative Study
Introduction and objectives: Both computed tomography (CT) and renal scintigraphy (RS) have been used to assess vascular anatomy, renal status, and split renal function (SRF). In this study, we used a recently developed software that facilitates renal volumetric evaluations to compare RS and automated CT volumetry for assessing residual renal function, and thus estimating postoperative renal function after donor nephrectomy.
Methods: Fifty-one cases of donor nephrectomy were analyzed. Residual renal function was estimated based on RS and CT volumetry. The correlation between the postoperative estimated glomerular filtration rate (eGFR) and expected SRF, measured using RS and three types of CT volumetry data (ellipsoid, thin-slice, and 5-mm slice data), was determined.
Results: The correlation coefficient between actual eGFR and expected SRF were significantly associated at each time point and modality (p<0.0001). At any time point, the difference in correlation coefficient between RS and 5-mm volumetry was significant (p-value: 0.003-0.018), whereas the differences in correlation coefficients between RS and the tri-axial volume calculation, and the tri-axial volume calculation and 5-mm volumetry, were generally statistically insignificant.
Conclusions: Expected SRF was estimated more accurately by CT volumetric calculations (especially 5-mm-slice-based volumetry) than RS.
期刊介绍:
Concise but fully substantiated international reports of clinically oriented research into science and current management of urogenital disorders form the nucleus of original as well as basic research papers. These are supplemented by up-to-date reviews by international experts on the state-of-the-art of key topics of clinical urological practice. Essential topics receiving regular coverage include the introduction of new techniques and instrumentation as well as the evaluation of new functional tests and diagnostic methods. Special attention is given to advances in surgical techniques and clinical oncology. The regular publication of selected case reports represents the great variation in urological disease and illustrates treatment solutions in singular cases.
