[Ureteral reimplantation using the psoas bladder hitch. Apropos of 42 cases]

42 cases of ureterocystoneostomy with psoas hitch were performed: 22 boys, 20 girls. The majority of the cases were done between ages 4 and 6. Initially 8 cases presented with reflux, 9 with megaureter and reflux, 20 with megaureter without reflux, 5 cases of ureterocele with duplication. 2 cases were done as a primary procedure, 4 cases as a part of undiversion, 36 after failure of a reimplantation either for reflux (13) or for stenosis (23). The technique is described: four cases were done bilaterally. Another procedure accompanied the psoas hitch: 20 ureteral modelage, 3 transuretero-ureterostomies. Follow up varied from 1 to 13 years with good results in 27 cases, fair results in 10 and poor results in 5.
