ABSTRACT
BACKGROUND: Vesicoureteral reflux (VUR) is a common urologic complication of pediatric kidney transplant, though there is little data on the effect of VUR on histologic graft changes or graft survival. METHODS: All pediatric patients who received a kidney transplant from 2007 to 2020 were selected for retrospective chart review. All participants underwent a voiding cystourethrogram (VCUG) at a 6-month post-transplant. Patients were then categorized into two groups based on vesicoureteral reflux grade: no/low-grade VUR (grades 0-2) and high-grade VUR (grades 3-5). Outcomes collected included graft failure rates, graft function, urinary tract infections (UTIs), proteinuria, and Banff scores at 3- and 12-month post-transplant surveillance kidney biopsies. RESULTS: There were 74 pediatric patients who received a kidney transplant in the designated time-period, and of those 39 had no/low-grade VUR and 35 had high-grade VUR. There was no difference in graft failure among the two groups over time when stratified for age (p = 0.389, CI 0.53-5.08). Patients with high grade VUR had a higher risk of UTI development overall (RR 1.89, 95%CI 1-3.6, p = 0.041), mostly accounted for from increased development of febrile UTI (RR 1.66, 95%CI 1.1-2.6, p = 0.038). CONCLUSIONS: Unselected pediatric kidney transplant recipients with high-grade vesicoureteral reflux on VCUG at a 6-month post-kidney transplant are more likely to have febrile UTI compared to those in the low-grade VUR group. There is no difference in graft survival among the two groups.
ABSTRACT
Background: Screening for early detection of microalbuminuria signaling kidney disease should begin as early as the time of diagnosis of youth-onset type 2 diabetes. This quality improvement initiative aimed to standardize urine nephropathy screening in pediatric patients with type 2 diabetes at a tertiary academic medical center and increase a baseline screening rate of 56%-75% over 6 months (September 2022-February 2023) and sustain that increase for 6 months (March through August 2023). Methods: A multi-disciplinary team used quality improvement methods and iterative Plan-Do-Study-Act cycles. Targeted interventions included previsit planning workflow, education, and a new-onset triage protocol. The team collected data at baseline and prospectively by reviewing electronic medical records. The primary outcome measure was pediatric type 2 diabetes clinic visits in diabetes clinic with urine nephropathy screening before or on the visit date. Results: A total of 121 youth were scheduled for T2D clinic visits between September 2021 and August 2023. The mean age was 14.5 years, and 60% were women, 40% were non-Hispanic Black, 28% were Hispanic/Latino, and 15% reported Spanish as their preferred language. Following the interventions of this project, urine nephropathy screening increased from 56% to 75%, and this change was sustained for 6 months. Conclusions: Interventions focused on efficient recognition of the population needing screening, coordinated internal processes around screening, a shared understanding between all stakeholders, and practical support in the healthcare system increased urine nephropathy screening with sustained improvement.
