Background and purpose: Urinary tract anomalies are responsible for urinary tract infection (UTI) in more than 30% of children.The present study was carried out to determine the prevalence of urinary tract anomalies in children with pyelonephritis referred to Amirkola Children Hospital during 2010-2020.Materials and methods: In this cross-sectional study, all children with UTI admitted to Amirkola Children Hospital during 2010-2020 were enrolled.
The inclusion criteria were children aged between 2 months and 18 years, positive signs read more and symptoms of UTI, and positive urine culture with reliable sampling.Children with a positive history of surgery on the urinary tract were excluded.Imaging studies included ultrasonography, DMSA, DTPA, VCUG, RNC, and IVP for the diagnosis of anomalies in the urinary tract.
Results: Among 381 children with pyelonephritis, the mean age was 37.1+41.3 months, and 337 (88.
5%) children were girls.One hundred forty-nine (39.1%) children had urinary anomalies.
The most anomalies were VUR, ureterovesical junction obstruction, cent dyyni Ureterocele, and ureteral duplication in 112(75.16%), 11(7.38%), 9(6.
04%), and 8(5.36%) of children, respectively.A significant difference was observed between age and anomaly prevalence (P=0.
04), but there was no significant difference between sex and prevalence of anomaly (P=0.3).Conclusion: The results of the study showed that about 39% of children with UTI had urological anomalies, the most common cause of which was VUR, and other urological anomalies (about a quarter) such as ureterovesical junction obstruction, Ureterocele.
In addition to vesicoureteral reflux, paying attention to other urological anomalies in these children is recommended.
