Purpose: to assess the results of the Lich-Gregoire procedure in the treatment of primary vesicoureteral reflux (VUR). Materials and methods: In a 2.5-year period, 141 children with primary VUR underwent a vesicoureteral reimplantation using the Lich-Gregoire procedure in 101 patients (158 ureters) and the Cohen procedure in 48 patients (68 ureters). Patients were evaluated retrospectively in a non randomized fashion and data were recorded about: age, indications for surgery, days with the bladder catheter, length of stay, and short and long-term complications. Results: The control average time was 1.71 years (from 8 months to 3.5 years). A) Early complications. No obstruction was seen in this series. Five children (8.6 of the bilaterally simultaneously operated) showed urinary retention, but only three needed replacement of the bladder catheter and only one of them needed temporary clean intermittent catheterization. Nausea, vomiting, pain and hematuria were sporadic and limited in time. B) Late complications. The long-term results were good (95%). Seven ureters (4.4%) had persistent VUR and 3 children (6.7% of the unilateral cases) had contralateral VUR. Only 3 ureters needed a new surgical treatment (2%) for persistent ipsilateral VUR. Short and long-term complications, days with bladder catheter and length of stay in the hospital were significantly smaller in the group of patients operated with Lich-Gregoire procedure than in patients operated with the Cohen technique. Conclusions: The Lich-Gregoire procedure is a technique associated with shorter postoperative hospitalization and less discomfort, pain and hematuria than the intravesical technique. Both techniques were effective in correcting VUR. Extravesical reimplantation can cause transitory bladder dysfunction in a small percentage of the bilateral cases.
