Why do children have frequent and painful urination?

There are many reasons that may cause children to feel uncomfortable when urinating, such as frequent and painful urination. Frequent and painful urination may be caused by urinary tract infection. After a child has a urinary tract infection, he or she may also have varying degrees of fever and his or her face may become pale. Let’s take a look at some of the main reasons why young children experience frequent and painful urination.

Why are babies prone to urinary tract infections?

This is mainly determined by the baby's physiological and anatomical factors and environmental factors. The urinary tract of infants and young children is prone to retrograde infection. Since they often use diapers or wear open-crotch pants, the urethral opening is often contaminated by feces and other unclean substances. It can be said that various pathogens such as Escherichia coli, Proteus and Staphylococcus aureus accumulate around the urethral opening, looking for an opportunity to invade. Infants, especially girls, have short urethras and poor sphincter function, so bacteria can easily ascend along the urethra to the bladder, causing bladder infection or renal pelvis infection. In addition, infants and young children have an incomplete immune system and poor defense capabilities, which not only makes them prone to ascending infection, but also may lead to descending infection of the urethra due to susceptibility to upper respiratory tract infection, pneumonia, bacteremia, etc.

Children of different ages show different symptoms:

In the neonatal period, systemic symptoms are predominant, including fever, poor feeding, pallor, vomiting, diarrhea, abdominal distension and other non-specific manifestations. There may also be growth stagnation, slow weight gain, and even convulsions, lethargy, jaundice and other manifestations.

In infancy and childhood, systemic symptoms are still the main ones, such as fever, recurrent diarrhea, etc. Urinary tract symptoms such as frequent urination, urgency, and pain only become more obvious with age.

Therefore, when infants and young children cry when urinating, urinate frequently, or have persistent diaper rash, unexplained fever, or persistent fever, this disease should be considered. Go to the hospital to collect clean midstream urine for urine routine, urine culture and other tests to confirm the diagnosis.

Generally, bed rest is required during the acute phase of treatment. Drink more water, urinate frequently, and reduce the time bacteria stay in the bladder. Remember to change diapers frequently and keep the perineum clean and dry. After each bowel movement, wipe from front to back and clean the baby's butt with warm water. In addition, actively cooperate with the doctor's treatment plan and use antibiotics reasonably. After the acute course of treatment, the patient should be reexamined once a month for a total of 3 times. Only those without recurrence are considered cured. For patients with recurrent recurrence, review every 3 to 6 months for 2 years or longer.

Therefore, when you find that your child has frequent and painful urination, it is best to take him to the hospital for examination in time. At the same time, you should give your child some warm water after school. This can help the body to quickly excrete a large amount of toxins and reduce the residence time of bacteria in the bladder. After recovery, you should also go to the hospital for a follow-up examination on time.
