MATERIAL AND METHODS Sixty-one patients were included in the study retrospectively. Patients were divided into three groups: Group 1 (n: 26) without LUTD; Group 2 (n: 23) with LUTD and Group 3 (n: 12) was composed of the patients who were not toilet trained preoperatively. Patients were reassessed about de novo or persistence of LUTD at least seven years later. RESULTS Mean age of the patients was 7 years (1–15 years) and surgical approach resulted in a 92 % success rate. Mean follow-up period was 10 years (7–12 years). Post-operative LUTD was present in 6 out of 26 (23 %) in Group-1; 12 out of 23 (52 %) in Group-2, and 1 out of 12 patients (8.3 %) in Group-3. Presence of LUTD before surgery and bilateral repair in the same setting were the predictive risk parameters for the presence of LUTD on long-term follow-up. LUTD was higher in Group-2 (52 %) than in Group-1 (23 %) and 3 (8.3 %) (p=0.015). De-novo LUTD presence was found significantly in Group-1 when compared to pre-op and post-op LUTD presence with Wilcoxon analysis (p= 0.031). CONCLUSIONS LUTD may not resolve after ureteroneocystostomy and additional therapy could be necessary. Due to the probability of damage to the ureterovesical nerve and/or disturbed bladder dynamics, de novo LUTD may occur in patients with bilateral high-grade reflux and without LUTD before ureteroneocystostomy. 08:43–08:52 Discussion
