[Preoperative evaluation of renal carcinoma using multi-detector CT]

When laparoscopic nephrectomy is performed, the limited visibility of many anatomical structures requires additional pre-operative information. However, most of this information can be highlighted by Multislice-CT which depicts all the vascular structures while providing an essential road mapping for the surgeon. Besides underlining arterial abnormalities, this technique allows to depict venous pathways and tumoral invasion. This review illustrates the various potential applications of Multislice-CT in the evaluation of renal tumors.
