    Abstract:
    PURPOSE: Various techniques of ureteral reimplantation have been described for correction of vesicoureteral reflux. We report our experience regarding the safety and efficacy of a modified Lich-Gregoir extravesical approach. MATERIAL AND METHODS: From January 1991 to January 1996 we evaluated prospectively 256 patients who underwent a modified Lich-Gregoir procedure for correction of vesicoureteral reflux. A total of 385 vesicoureteral units were reimplanted, including 41 duplex systems. The modification to the Lich-Gregoir technique we used consists of ending the paraureteral myotomy with an inverted Y, which permits easier detrusor muscle reapproximation. RESULTS: This procedure was successful initially in 214 of 237 patients, as confirmed by a normal voiding cystourethrogram 4 to 6 months postoperatively. Of the 237 cases persistent vesicoureteral reflux developed in 13 patients, which resolved spontaneously in 9 after 1 year, contralateral reflux developed in 8, which was treated conservatively, and ureteral obstruction developed in 2. Thus, the 1-year overall success rate was 96%. Urinary retention developed in 12 children with bilateral reimplantation (8.3%) with successful recovery in all after conservative management with urethral catheter drainage of 1 week or less. The duration of hospitalization after surgery ranged from 1 to 3 days. CONCLUSIONS: The modified Lich-Gregoir technique of extravesical ureteral reimplantation is successful, simple to perform, reproducible and associated with low morbidity. It also requires minimal hospital stay. These results should encourage the use of this technique when indicated to correct vesicoureteral reflux in children.
