[Therapy of vesicoureterorenal reflux in childhood--report of 10 years' experience with Lich-Gregoir antireflux-plasty].

In a ten years period 186 extravesical antireflux operations (Lich-Gregoir) were performed in 145 children. Indications, surgical technique, postoperative complications, reflux recurrence, and pyelonephritis are described and discussed with regard to the literature. In 66 children followed up for more than 4 years there were 6 cases (9%) with persisting pyelonephritis. No postoperative ostium stenosis occurred. The authors prefer the extravesical approach because of its relative easy operative technique, its safety in removing the reflux, and the avoidance of operative manipulations at the ostium, which may cause postoperative ostium stenosis.
