The results of extravesical ureteroplasty (Lich-Gregoir technique) for primary extravesical reflux in 62 children with 82 refluxing renal units are evaluated. Postoperative radiograms revealed persistent reflux in 5 (6.1 per cent) and obstruction in 1 (1.2 per cent) of the renal units. Of 7 patients in whom bilateral reflux had been noted previously but who had unilateral reflux at the time of operation, unilateral repair resulted in absence of reflux on the contralateral side in 6. The favorable success rate, low morbidity and median 5-day hospitalization support the use of extravesical ureteroplasty for uncomplicated reflux.
