Utilidad de la angiotomografía multicorte en la valoración vascular del donador renal.

To determinate the Multisection Computed Tomography Angiography (CTA) utility in the renal donors evaluation, and to compare the results with the surgical findings. Material and methods: CTA was made in all the renal donor candidates, with 4D reconstructions for the vascular evaluation and was correlated with surgical findings. Results: We include 43 patients, 21 female (48%) and 22 (52%) male, ages ranged from 20 to 56 years. The arterial variants anatomical were: 33 (77%) single renal artery, 10 (23%) with polar arteries (normal anatomical finding), 7 male, 3 female; 7 unilateral and 3 bilateral. In 26 patients, the ACT findings with surgery were correlated. Of these 12 women and 14 men, with 19 left nephrectomy and 7 right nephrectomy. The correlation were in 25 patients (96%), just only one the diagnosis was different, the Spearman's correlation coefficient value is 0.96, kappa 0.78, concordance 0.96, all of them with p < 0.05, positive predictive value of 100% and negative predictive value of 96%. All patients had a single vein. Conclusion: The CTA with 4D reconstructions, is accurate to describe the vascular renal anatomy, is less expensive, requires less time and is not invasive.
