Contralateral vesicoureteral reflux is one of the most detestable complications after successful unilateral ureteral reimplantation of unilateral reflux. We searched for the risk factors for the new onset of contralateral reflux postoperatively. We reviewed 18 cases of unilateral reflux we had treated with unilateral ureteroneocystostomy. To determine the predictive factors of contralateral reflux, we investigated several factors including sex, age, laterality, reflux grade and surgical procedure. Contralateral reflux occurred in 4 patients after unilateral ureteroneocystostomy. No statistically significant prognostic factor was proved with a new onset of contralateral reflux. However, female patients (50%), those patients 5 years old or younger (36.5%), and those who underwent the Cohen procedure (30%) had a greater tendency of developing contralateral reflux compared to male patients (14%), patients more than 5 years old (10%), and those who underwent the Politano-Leadbetter procedure (14%). Although we could not statistically identify any risk factor for a new onset of contralateral reflux from the preoperative evaluation, we realized that those who underwent ipsilateral reimplantation should be carefully followed if they are female or less than 5 years old.
