[Lich-Gregoir ureteroneocystostomy: experience of a North-American pediatric center].

Between August 1990 and December 1993, 140 children underwent Lich-Gregoir antireflux plasty. Twenty-eight boys and 112 girls were included with an age range of 4 months to 15 years (average 5.8 years). Twenty-seven of 220 ureters reimplanted were duplicated. At 6 months follow-up, 10 of 140 children had persistent reflux and 5 had controlateral reflux. Two patients had obstruction and 1 needed reintervention. At 1 year follow-up, only 3 children had persistent reflux and none controlateral. The Lich-Gregoir antireflux procedure is a simple surgery with minimal morbidity and excellent success rate.
