Influence of ureterovesical anastomosis technique on the incidence of vesicoureteral reflux in renal transplant recipients.

Urological complications of allogenic kidney transplantation include vesicoureteral reflux which can result in graft threatening urinary tract infection. To prevent this complication several ureterovesical anastomosis techniques have been developed. Authors present a comparison of three different techniques: extravesical without antireflux 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 cystography and urine culture performed. The incidence of vesicoureteral reflux varied from 13.3% to 50%, depending on the anastomosis technique. No correlation between type of anastomosis and urinary tract infection was found.
