Question
A three-year-old boy was found to have blood in his urine one year ago, but there were no pain or discomfort, and he appeared lively. After four examinations, the hematuria condition has not improved, and the doctor has prescribed antibody injections and medication for treatment, but the effect is limited. What could be the possible causes of this condition? Is it severe? How should further examinations be conducted?
Answer
When considering the causes of hematuria, in addition to hematuria itself, attention should also be paid to whether there are other abnormalities such as proteinuria or pyuria in the urine examination. There is a condition called nocturnal hematuria that is similar to the described symptoms. First, it is recommended to have the child’s external genitalia examined at the hospital to confirm if there are any developmental issues, such as phimosis or tight foreskin, which may lead to the accumulation of urinary debris under the foreskin, causing symptoms such as frequent urination or enuresis. Treatment should be tailored to specific situations and should avoid spicy and irritating foods while encouraging the child to drink more water.
