Urological complications of allogenic kidney transpl: ntation include vesicoureteral reflux which can result in graft threatening urinary tract infection. To prevent this complication several ureterovesicalanastomosis techniques have been developed. Authors present a comparison of three different techniques: extravesical without ani reflux mechanism, extravesical Witzel-lich with antireflux mechanism and intravesical Laedbetter-Politano with antireflux mechanism. 39 patients were selected randomly from a cohort of 420 allogenic kidney recipients (follow up time 10-147 months). All patients had voiding cys ographyand urine culture performed. The incidence of vesicoureteral reflux varied from 13,3% to 50%, depending on the anastomosis techr ique. No correlation between type of anastomosis and urinary tract infection was found.
