title: Renalase Levels in Children with Solitary Functioning Kidney.
abstract: OBJECTIVE
  To measure serum and urine renalase levels in children with a single kidney, and to compare with a reference group.
  
  
  METHODS
  Participants were: solitary kidney (n=36) and healthy children (n=57). Renalase levels were measured using the immunoenzymatic method.
  
  
  RESULTS
  Serum and urine renalase levels were significantly lower in patients with a solitary kidney compared to healthy children. Urine renalase/creatinine values were negatively related to serum creatinine and positively related to glomerular filtration rate. Significant correlations between renalase levels and blood pressure were not found.
  
  
  CONCLUSIONS
  Prognostic importance of reduced renalase levels in children with a single kidney can only be quantified by further longitudinal study.
