PREOPERATIVE EVALUATION OF LIVING DONORS USING COMPUTED TOMOGRAPHY ANGIOGRAPHY (CTA) AND CONVENTIONAL ANGIOGRAPHY: COMPARISON WITH INTRAOPERATIVE FINDINGS

CTA is a minimally invasive modality to image the vasculature without the morbidity of direct large vessel vasculature access and its major indications in urology are assessment of the renal vasculature in preparation for donor nephrectomy, identification of extravessel in evaluation of ureteropelvic junction obstruction and for diagnosis of renal artery stenosis. To assess the accuracy of CTA for the evaluation of renal vascular anatomy for preoperative donor assessment in living kidney transplantation. CTA of 70 living donor kidney donors were analyzed by two blinded observers and compared with intraoperative findings. Similar findings of conventional angiography of 30 living donor kidney donors compared with intraoperative observations. In CTA group there were two patients each with two main renal veins on surgery that hadn’t been seen on CTA. In the second group there was one patient with unrevealed two main renal veins before surgery. In both groups, all patients were diagnosed accessory renal arteries if existed. Overall, the accuracy for renal main artery anatomy was 100% for both CTA and conventional angiography. Accuracy for renal main vein anatomy was 97.1% and 96.6% for CTA and conventional angiography respectively. Hence, these two modalities had comparable results for renal main vasculature anatomy detection.
