小児膀胱尿管逆流に対する Cohen 術式の経験

抄録

As antireflux operation for vesicoureteric reflux, Politano-Leadbetter procedure was performed in 54 infants and children (88 ureters) during 10 years until 1983. Two infants with IVth degree refluxing megaureter presented a stricture at ureterovesical anastomotic junction which required a secondary repair. We found this procedure is rather difficult and complicated one especially in young infants. Since 1984, Cohen technique was performed in 13 infants and children (24 ureters) and satisfactory results were obtained except one ureter which showed persistant reflux postoperatively in a patient with severe neurogenic bladder. From our experience, the Cohen technique is simpler and safer than Politano-Leadbetter procedure. We recommend, therefore, this technique for children with vesicoureteric reflux, particularly in young infants.
