Objectives: To compare the findings of helical com­puted tomography (CT) angiography and the intraopera­tive findings in voluntary kidney donors. Methods: This was a prospective study evaluating 28 voluntary kidney donors from January 2001 to December 2002 who underwent a preoperative CT angiography with a 20 minute intravenous urogram film and was compared with intraoperative findings during nephrectomy to de­termine the accuracy of CT angiography. Donors consti­tuted 21 females and 7 males and all were related donors with mean age of 35.5 years (19 to 55 years). Results: Intraoperative findings correlated in 25 out of 28 patients (88.75%). Among those 3 patients, one pa­tient had an upper polar accessory artery, another had a lower polar artery and the third patient had an early branching respectively. Conclusions: Helical CT and 3-D reformatting allowed improved vascular imaging and has the potential for fu­ture single imaging method for donor evaluation. It has been cost effective also. It needs a dedicated radiologist for interpretation. About 10% of renal arteries are not seen on helical CT renal arteriograms when compared with findings at surgery.
