It can occur until the age of six weeks. If you are more than six years old, you need to go to the hospital for further examination to see if there is enuresis. 2. Urge incontinence, because of playing or because of passive factors that cause children to hold urine, there is uncontrollable incontinence, called urge incontinence. If a child is unable to urinate during class, so he or she is forced to urinate and appears unable to hold back his or her urine pants. This situation is mostly related to mental and psychological factors and environmental factors, and requires detailed inquiry.3. Peeing pants when infection occurs or when urinary tract injury occurs, such as a blow to the urethra, trauma or perineal area riding across injury, fall, etc., can cause urethral injury and the phenomenon of urine loss, or combined infection and congestion and edema of the mucosa of the urinary tract, causing patients to repeatedly urinate frequently and urgently, and the appearance of urine dripping on their pants.
