  2. Intraoperative cystography showed VUR, in 3 of 4 cases of bilateral VUR confirmed preoperatively and 4 ipsilateral ureters from 8 patients with single-sided VUR. There were no cases of intraoperative VUR that had not been diagnosed preoperatively. There was not apparent correlation between postoperative and intraoperative VUR grade (data not shown)
