The child always say can not urinate may be too little water, nervousness and other physiological factors, or may be urethral stenosis, bladder stones and other diseases. 1. Physiological factors: If the child’s daily water intake is low, it may cause the child to urinate less, and may appear to always urinate out of the situation. This is a normal phenomenon and is not a cause for concern. 2. Urethral stenosis: Urethral stenosis may be caused by trauma, infection, heredity, medical injury and other factors. The child may have difficulty urinating and may always say that he can’t urinate. 3. Bladder stones: Bladder stones may be the result of urethral stricture, urinary tract infection, diet and other factors. Symptoms are pain in the lower abdomen, difficulty in urination, hematuria and so on, and the affected children may appear to always say they can’t urinate. Therefore, if the child always says that he can’t urinate, parents need to pay attention to it, and can take the child to the regular hospital for relevant examinations to find out the cause of the disease.
