Introduction:

Although orthostatic proteinuira (OP) is the most common cause of proteinuira in children, little data exist about its prognosis. The aim of this study was to determine the follow-up of the cases with OP.

Material and methods:

Children who was diagnosed as OP by finding proteinuria on three consecutive random urine samples and no proteinuria on first morning urine samples at a screening study on schoolchildren were evaluated 3 years later. Proteinuria was defined as ≥1+ on urine strip test or urinary protein/creatinine ratio > 0.2 (mg/mg).

Results:

7 children, 5 girls and 2 boys, with a mean age of 13.5 ± 3.3 (range: 9-17) years were included in the study. None of them had proteinuria on both urine strip test and on urinary protein/creatinine ratio, three years after the diagnosis of OP.

Conclusions:

Our findings suggest that OP resolves within a few years, and it seems to be a temporary phenomenon in school-aged children.
