Question
A 7-year-old child suddenly began to urinate frequently around 10 PM, and a urine test revealed three plus signs of protein. There were no related symptoms before this situation occurred. What could be the possible cause?
Answer
Under the stimulation of inflammation, symptoms such as frequent urination, urgency, and pain during urination may occur, collectively known as urethral irritation symptoms. Other non-inflammatory irritants such as urethral stones or foreign objects may also cause this. Additionally, reduced bladder capacity (such as bladder tumors, pregnancy-related uterine compression, tuberculous bladder spasm, or large bladder stones) or psychogenic frequent urination may also lead to such symptoms. It is recommended to go to the hospital for further detailed examination to determine the cause and receive effective treatment. The treatment method should be determined based on the cause of the frequent urination and a hospital check-up is suggested.
