COMPARISON OF MULTI-SLICE SPIRAL CT AND MAGNETIC RESONANCE IMAGING FOR RENAL VASCULAR ANATOMY FOR LIVE DONORS.

Abstract

O221 Purpose: This study was designed to assess the role of multislice CT angiography and magnetic resonance angoigraphy (MRA) in evaluation of renal vascular anatomy for open and laparoscopic live donor nephrectomy. Material and methods: Thirty seven prospective donors underwent both CT and gandolinium enhanced MR angiography on separate occasions before surgery. In addition to axial images, Multiplanar reconstruction and Maximum intensity projections were used to display renal vascular anatomy. A total of 26 patients have undergone surgery including eighteen laparoscopic procedures whereas eight donors had Rt-open nephrectomy. Three donors decided not to proceed, another three were unsuitable for organ donation because of incidental findings on imaging. Four donors are awaiting procedure. Laparoscopic donor surgery was only considered if the renal vascular anatomy was favourable on the left side otherwise right sided open procedure was performed. CT and MRI images were analysed by two radiologists independently. Radiological and surgical correlation was made after donor surgery. Results:FigureConclusion: CT angiography was found to be superior to MR angiography in this study for arterial and especially for venous anatomy, which is more relevant to laparoscopic surgery. CT angiography is therefore more useful to plan laparoscopic donor nephrectomy.
