Answer

Gross hematuria usually disappears within 1-3 weeks but may be exacerbated by physical activity. C3 concentration returns to normal in more than 95% of patients by the end of 8-10 weeks. Microscopic hematuria usually disappears after 6 months, but its presence for as long as 1 year should not cause undue concern, and even more prolonged hematuria (1-3 y) has been observed in some patients who ultimately have demonstrated complete resolution of their renal disease. Strongly consider the possibility of chronic renal disease when both hematuria and proteinuria persist longer than 12 months.
