Vesicoureteric reflux and urinary tract infection in children

Area of Science:

• Pediatric Nephrology
• Urology
• Public Health

Background:

• Vesicoureteric reflux (VUR) has been linked to renal damage since 1960.
• Reflux nephropathy (RN) describes VUR-induced kidney damage, affecting 10-20% of children with hypertension or end-stage renal disease.
• Sex differences exist in RN development: males often have congenital abnormalities, while females develop it through acquired conditions like recurrent urinary tract infections (UTIs).

Purpose of the Study:

• To review current understanding of reflux nephropathy (RN) and its association with urinary tract infections (UTIs).
• To discuss the impact of antenatal ultrasonography on diagnostic guidelines for VUR.
• To highlight the need for further research on prophylactic antibiotics for children with VUR.

Main Methods:

• Literature review of studies on vesicoureteric reflux (VUR) and reflux nephropathy (RN).
• Analysis of current UTI guidelines and their evolution.
• Discussion of diagnostic approaches and long-term management strategies.

Main Results:

• Antenatal ultrasonography has reduced the need for routine urinary tract abnormality investigations after a first UTI.
• Recurrent UTIs and a family history of VUR remain key indicators for further evaluation.
• The long-term efficacy of prophylactic antibiotics in children with VUR requires further investigation.

Conclusions:

• Current UTI guidelines require updates considering advances in antenatal screening.
• Further research is crucial to determine the long-term benefits of prophylactic antibiotics in managing VUR in children.
• Identifying children at risk for RN progression remains a priority.
