INTRODUCTION: Posterior urethral valves (PUVs) is a congenital condition in which an obstruction in the urethra prevents drainage of urine from the bladder in males, with up to 60% of children diagnosed developing chronic kidney disease (CKD). The primary aim of this study was to identify novel factors that may predict development of CKD and end-stage real disease (ESRD) in children with PUVs to potentially address modifiable factors and delay progression. The secondary aim was to compare rates of catheterization and incontinence between our patients and other case series to provide information to parents about longterm bladder outcomes.
METHODS: A single-center, retrospective cohort study was performed of all children referred to our multidisciplinary clinic for PUV diagnosis between 2005 and 2019. Univariable associations of different variables with the composite outcome CKD or ESRD were evaluated.
RESULTS: Thirty of 46 patients (65%) developed CKD, with the majority (40%) being stage 2 CKD (n=12). Seven of 30 patients (23%) developed ESRD requiring renal replacement therapy. Fourteen of 26 (30%) required clean intermittent catheterization (CIC) initiation, with a median CIC initiation age of 4.3 years. Creatinine nadir post-valve ablation, oligohydramnios, and initiation of CIC are significant predictors of CKD development.
CONCLUSIONS: This review reiterates that children born with PUVs have a high morbidity rate, with a high proportion developing CKD. Using a multidisciplinary approach to PUV patient care allows for better family education, early intervention of bladder dysfunction, and possibly better long-term preservation of renal function.
