Abstract:
OBJECTIVE:To study the long-term prognosis of vesicoureteral reflux in children.
METHODS:A retrospective analysis was performed for the clinical data of 138 children (218 ureters with reflux) who were diagnosed with vesicoureteral reflux for the first time from November 2005 to March 2017 and received medical treatment and regular follow-up. According to the initial grade of reflux, the ureters with reflux were divided into a low-grade group (141 ureters, grade I-III) and a high-grade group (77 ureters, grade IV-V), and the two groups were compared in terms of clinical data and follow-up results.
RESULTS:Among the 138 children, there were 82 boys and 56 girls. Their age ranged from 31 days to 10 years at the time of confirmed diagnosis, with a median age of 8 months. The follow-up time ranged from 8 months to 7 years, with a median follow-up time of 1.4 years. At the time of confirmed diagnosis, the high-grade group had significantly higher levels of urinary N-acetyl-β-D-glucosaminidase, urinary microalbumin and urinary immunoglobulin G than the low-grade group (P<0.05). Among the 218 ureters with reflux, 132 (60.6%) achieved a reduction in the grade of reflux (among which 74 achieved complete disappearance of reflux), 43 had no change in the grade of reflux, and 43 had an increase in the grade of reflux. Compared with the high-grade group, the low-grade group had a significantly higher complete remission rate (41.1% vs 19.5%, P=0.001) and a significantly shorter time to complete remission of reflux (P=0.002).
CONCLUSIONS:Most children with vesicoureteral reflux can achieve a reduction in the grade of reflux or even complete disappearance of reflux during follow-up, and the children with low-grade reflux have better prognosis than those with high-grade reflux.
