Dr my 10-year-old circumcised boy during these days of Covid wets his trousers. I do not know why. Alisha
When one wets his trousers with urine, it is likely that he has lost control over the way he passes urine. In school when a teacher refuses to give permission to a student to the bathroom, or because of fear, say during examinations, they may wet their pants uncontrollably.
Children under three years may wet their panties with urine because they have not yet developed control over urination which control improves with age.
That said, stress and anxiety, urinary tract infections, constipation and taking a lot of drinks especially containing caffeine may all result in a child who had attained control over their bladders to lose control hence wetting their pants.
The wetting of pants requires investigations to be managed properly, but this should be done taking into account that children may get drops of urine into their panties because no parent teaches them how to avoid an after dribble.
Men are prone to an after dribble (wetting panties after passing urine) as they get older and get enlarged prostates so that even after shaking the penis a few drops may still remain and wet the pants.
Very few parents teach their sons how to shake the penis after urinating, risking wetting their pants due to some drops remaining in the urethra after passing urine.
Leaking stool encopresis, may be associated with leaking urine since both may result from constipation and emotional issues.
The average age for puberty in boys is around 12 years but in cases of precocious puberty boys may start puberty before 9 years so that what you may be calling urine may actually be because of wet dreams common during puberty.
