Evaluation of Transient Proteinuria in Children

Matjaž Kopač


Proteinuria is a common laboratory finding in pediatric practice and can be found incidentally in children at school screening tests and during evaluation for other reasons. Usually only repeat urine testing is neccessary to confirm transient nature of this phenomena. However, a small subset of these children may have persistent proteinuria but they are at highest risk for developing chronic kidney disease. Aggressive diagnostic procedures are usually not necessary at the beginning unless there is nephrotic range proteinuria or other parameters suggesting severe renal disease. Orthostatic proteinuria is one of the most common causes of proteinuria in children and has excellent prognosis with spontaneous resolution in most individuals.
