Abstract Objectives This study was designed to compare the clinical data of vesicoureteral reflux (VUR) in children with and without an allergic constitution. Methods The clinical data of patients hospitalized with VUR due to a urinary tract infection (UTI) between September 1, 2019, and December 31, 2020, were retrospectively analyzed. The patients were divided into two groups: an anallergic constitution group (AC group) and a non-allergic constitution (NAC group), and their UTIs and VUR were compared at baseline and during the follow-up period. Results (1) Between September 1, 2019, and December 31, 2020, a total of 284 children were hospitalized at Shengjing Hospital Affiliated to China Medical University due to a UTI. These children included 37 cases with primary VUR and 247 cases without VUR (including 59 cases of non-VUR urinary malformation). The proportion of children with an allergic constitution was significantly higher in the patients with VUR than it was in those without VUR or with other urinary malformations (72.97% vs. 48.18% vs. 50.85%, P = 0.005, 0.032). (2) At baseline, the levels of immunoglobulin and immunoglobulin E in the AC group were significantly higher than those in the NAC group (P = 0.042, 0.017). (3) During the follow-up period, the number of recurrent UTI cases in the AC group was significantly higher than that in the NAC group (0.70 ± 0.91 vs. 0.10 ± 0.32, P= 0.005). The difference between the two groups in the VUR remission rate was not statistically significant (40% vs. 50%, P = 0.563). (4) During the follow-up period, the differences in the remission rates of recurrent UTIs and VUR in the two groups were not statistically significant. Conclusions The incidence of having an allergic constitution is high in patients with VUR, and patients with an allergic constitution present with a higher frequency of recurrent UTIs.
