Multidetector-row CT angiography for preoperative evaluation of potential laparoscopic renal donors: how accurate are we?

The purpose of this study was to evaluate multidetector-row computed tomography (MDCT) angiography in preoperative evaluation of renal donors for renal vascular abnormalities. Eighty-one patients underwent renal MDCT angiography and laparoscopic donor nephrectomy. MDCT angiographic findings were compared with surgical findings. The sensitivity and specificity of MDCT angiography for detection of accessory arteries, prehilar renal artery branching, and renal venous anomalies were 88% and 98%, 100% and 97%, and 100% and 97%, respectively. CT findings agreed with surgical findings for accessory renal arteries, prehilar renal artery branching, and renal venous anomalies in 94%, 93%, and 98% of patients, respectively.
