Abstract

The incidence of contralateral reflux after unilateral reimplantation in children with primary unilateral vesicoureteral reflux(VUR) is reported to be 0.8- 32%. We evaluated the characteristics of contralateral reflux after endoscopic or open surgical correction of primary unilateral VUR in children. 30 children who underwent unilateral reimplantation by Paquin (25pts) and submucosal Macroplastique injection(5pts) were evaluated. The association between postoperative contralateral reflux and age, sex, ipsilateral implant side, postoperative urinary tract infection, and surgical method were evaluated. There were 18 male and 12 female patients. Initial reflux was observed in the right in 18 and 12 in left. The initial reflux grades were II, III, IV, and V in 2, 11, 14, and 3 patients, respectively. Postoperative urinary tract infection was observed in 4 patients of whom 1 had contralateral reflux. In conclusion, there was no single factor that could predict the development of contra- lateral reflux after unilateral correction of unilateral primary VUR. Furthermore, the fact that contralateral reflux occurred even after submucosal Macroplastique injection suggests that the method of surgery is not related to the subsequent development of contralateral reflux.
