[Urologic complications in renal transplantation in children]

Our results with 105 pediatric renal transplantations, are reviewed. The identified complications were: 4 ureterovesical stenoses, 1 pyeloureteral stenosis, 1 vesical rupture, 1 vesicoureteral reflux on native ureters and 1 acute urinary obstruction. These incidences were scattered among 5 patients of whom 3 had 2 complications each. All were surgically corrected and 4 of the kidneys are well-functioning at present. We analyze the factors possibly involved and suggest that donor and recipient related parameters might not be determinant, save for those patients afflicted with lower urinary tract anomalies, and that ureteral catheters may prevent urinary extravasation or fistulae.
