A lower trend of pooled (95% CI) time to 50% RIA was observed with CKRT [6.5 (5.1-7.8)] vs. PD [14.4 (13.3-15.5)].

Endoscopic ablation/incision of the valves is usually offered as the primary treatment of choice. Following this, a range of different clinical patterns are observed, each with varying bladder dysfunction and continence issues and associated with different grades of chronic kidney disease. This review outlines a systematic approach that could help pediatric nephrologists, pediatricians, and pediatric urologists, as well as nursing and allied health specialists, assess these children and develop well-informed management plans. The need for surveillance for bladder dysfunction (incidence approximately 55%), identification of red flags for progression to kidney failure (incidence approximately 20%), and multidisciplinary approach to care are presented, with a focus on reducing long-term morbidity in patients and difficulties for the families. Where possible, an alternative in resource-constrained situations is suggested.
