Vesico-ureteric reflux in children and young people undergoing kidney transplantation

Area of Science:

• Pediatric Nephrology
• Transplant Surgery
• Urology

Background:

• Vesico-ureteric reflux (VUR) is frequently observed in pediatric kidney transplant recipients.
• Prevalence ranges from 19-60% with anti-reflux procedures and up to 79% without.

Purpose of the Study:

• To investigate the implications of VUR in pediatric kidney transplants, particularly when associated with urinary tract infections (UTIs) and transplant pyelonephritis.
• To identify risk factors for UTIs and assess the impact of pyelonephritis on kidney allograft function.
• To explore strategies for reducing infection prevalence.

Main Methods:

• Review of existing literature on VUR in pediatric kidney transplantation.
• Analysis of risk factors, infection outcomes, and allograft function.
• Evaluation of preventative and management strategies.

Main Results:

• VUR is common, but its clinical significance is often linked to symptomatic UTIs.
• The impact of VUR-associated UTIs and pyelonephritis on acute and long-term kidney allograft function requires further clarification.
• Specific risk factors and effective infection reduction strategies are under exploration.

Conclusions:

• While VUR itself may not always be detrimental, its conjunction with UTIs and pyelonephritis in pediatric kidney transplants warrants careful monitoring.
• Further research is needed to elucidate the precise effects on graft outcomes and to develop targeted interventions.
