Pediatric simple hematuria

Where the number of red blood cells in the urine exceeds normal without clear systemic and urinary diseases and their symptoms (such as edema, hypertension, renal failure, etc.), it is simple hematuria. Simple hematuria is a symptomatic diagnosis. After excluding all kinds of diseases that can cause hematuria, only those who have asymptomatic, solitary hematuria (without proteinuria) whose cause is not clear, are ldquo; simple hematuria rdquo; . In the 1979 draft of the classification of kidney disease prepared by the Pediatric Nephrology Research Group in China in 1979, it was called ldquo; asymptomatic hematuria; and it was revised in 1981 as ldquo; simple hematuria rdquo ;. This name is similar to the so-called ldquo; isolated hematuria) in the world.
