“…[1][2][3][4][5] The potential value of MR angiography for preoperative evaluation has also been shown. 8,16 Halpern et al 9 compared contrast-enhanced helical CT angiography using single detector-row helical CT and contrast-enhanced 3D MR angiography for the preoperative evaluation of kidney donors.…”

“…Both computed tomography (CT) angiography and magnetic resonance (MR) angiography are increasingly accepted methods, thus replacing conventional catheter angiography DSA, for preoperative evaluation of living renal donors. [1][2][3][4][5][6][7][8][9] Halpern et al 9 compared the efficacy of contrastenhanced helical CT angiography using single detector-row helical CT and contrast-enhanced threedimensional (3D) MR angiography for the preoperative evaluation of kidney donors. Their results showed substantial agreement between these two modalities but disagreement in the interpretation of small arteries.…”

“…Traditionally, renal angiography and excretory urography have been used to evaluate the anatomy of renal arteries and renal function, respectively, in potential kidney donors. However, several studies have shown that helical computed tomography (CT) angiography can replace renal angiography and excretory urography in the evaluation of potential kidney donors (3)(4)(5)(6)(7)(8)(9). Hence, helical CT angiography has become an accepted method for the evaluation of living donors before they undergo laparoscopic nephrectomy.…”

Rapid Estimation of Split Renal Function in Kidney Donors using software developed for Computed Tomographic Renal Volumetry AbstractPurpose: To evaluate the speed and precision of split renal volume(SRV) measurement (SRV), which is the ratio of unilateral renal volume to bilateral renal volume, using a newly developed software for computed tomographic (CT) volumetry and to investigate the usefulness of SRV for the estimation of split renal function (SRF) in kidney donors.Method: Both dynamic CT and renal scintigraphy in 28 adult potential living renal donors were the subjects of this study. We calculated SRV using the newly developed volumetric software built into a PACS viewer (n-SRV), and compared it with SRV calculated using a conventional workstation, ZIOSOFT (z-SRV). The correlation with split renal function (SRF) using 99m Tc-DMSA scintigraphy was also investigated.Results: The time required for volumetry of bilateral kidneys with the newly developed software (16.7 ± 3.9sec) was significantly shorter than that of the workstation (102.6 ± 38.9 sec, p<0.0001). The results of n-SRV (49.7 ± 4.0%) were highly consistent with those of z-SRV (49.9 ± 3.6%), with a mean discrepancy of 0.12 ± 0.84%. The SRF also agreed well with the n-SRV, with a mean discrepancy of 0.25 ± 1.65%. The dominant side determined by SRF and n-SRV showed agreement in 26 of 28 cases (92.9%).Conclusion: The newly developed software for CT volumetry was more rapid than the conventional workstation volumetry and just as accurate, and was suggested to be useful for the estimation of SRF and thus the dominant side in kidney donors.

“…[3][4][5][6][7][8][9][10][11] Some of them concluded that CT angiography can be used in place of conventional angiography because the findings correlated well with surgical findings. [3][4][5][6][7] CT angiography has now become an accepted method for preoperative evaluation of living donors. 10 Kidneys with a single renal artery are generally preferred for renal allografts because a renal graft with multiple renal arteries is associated with a high incidence of vascular complications.…”
