[Vesico-ureteral reimplantation in kidney transplantation from living relative donor: extravesical or transvesical? Urologic complications and long-term results evaluation].

Results of two techniques of ureteroneocystostomy were evaluated in a series of 400 consecutive living renal transplantations. In the first 150 patients (group A) PAQUIN ureteroneocystostomy was utilized and in the second 250 (group B) DE CAMPOS-FREIRE technique was performed. Significant urological complications were seen in 13 (8.6%) patients of group A and in 10 (4%) of group B. Bladder leak occurred in 5 patients of group A and in only 1 of group B (P < 0.05). Complications related to ureteral stenosis and ureteral necrosis were comparable in the two groups. High pressure vesicoureteral reflux was demonstrated in 2 of 85 patients of group A and in 15 of 160 of group B (P < 0.05). Abnormalities of intravenous urography were significantly higher in group A. The incidence of immediate and delayed post-transplant urinary infection was not statistically different among the two groups. We advocate the use of DE CAMPOS-FREIRE approach over the PAQUIN reimplantation, not only because of the marginal differences in the incidence of urological complications, but also because of the technical advantages offered by the former approach.
