However, screening siblings for VUR remains controversial. We investigated the prevalence of VUR and renal cortical abnormalities in the sibling population in a large cohort of families with VUR.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS:<\/jats:title>\n                  <jats:p>Between 1998 and 2012, parents of index patients with grade III to V VUR were asked permission to screen siblings &amp;lt;6 years of age for VUR. Siblings were divided into 2 groups: siblings with a documented history of a previous urinary tract infection (UTI) and siblings who were screened for VUR and never had a UTI. A logistic regression model was used to determine independent risk factors associated with renal cortical abnormalities such as history of presentation, age, gender, and grade of VUR.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>There were 318 siblings in 275 families in the study. VUR was found after screening in 190 (60%) siblings and after a UTI in 128 (40%). Multivariate analysis revealed that siblings who had a previous UTI (odds ratio: 3.38), siblings with high grade reflux (odds ratio: 3.62), and siblings over 1 year of age (odds ratio: 2.84) were the most significant independent risk factors associated with renal cortical abnormalities.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>There is increased risk of renal cortical abnormalities in siblings with a previous UTI, siblings with high-grade VUR, and siblings over age 1 year. This information may help to counsel parents about the risk of VUR and reflux nephropathy in familial VUR.<\/jats:p>\n
