What are the causes of frequency of urination in children?

admin TAGS: 2017-10-08 16:22

What is the standard of frequency of urination in children? Normal child's frequency of urination is related to age. After the baby is born a month, about once every hour. One year old about once every two hours. Only once every three hours after three years of age. After adolescence (12 years old), close to adults every four or five hours to take a urine. These are just an average. The frequency of each child is a bit different. The so-called urinary frequency should be beyond the normal range of children usually, rather than the figures on the book to do a strict comparison.

There are many reasons, we should first rule out the common reasons, and then check those rare causes. As to where to start, ask disease history and serious physical examination can provide important clues. Whether there is urgency, dysuria? Drink more water than ever? Will it be enuresis at night? What disease in the past, what surgery have done? What is the recent incident to make the child worried and so on. The following are some common reasons:

1. Urinary tract infection: due to bladder inflammation, sensitive, children will have urinary frequency, urgency, and even dysuria. Urine looks more turbid, and even blood. If the kidney is also affected, the child may have fever, vomiting. The fastest method of examination is urine, microscopic examination and urine culture. 

2. Diabetes: asked the detailed of disease history will find these children thirsty, drink plenty of water. Some is caused by the hot weather, the best way is to let the children and parents to make a water intake and urine excretion diary. Diagnosis can be clear at a glance. But some are due to diabetes. Last month, I saw a child transfer to pediatric outpatient department of urology, in addition to his thirst, the spirit is not good, light weight. He was suspected of diabetes. Immediately take routine urine test, found very high urine sugar. The diagnosis was confirmed by blood sugar. After controlling the acidosis, start giving the child insulin. There are other and endocrine-related polyuria. 

3. Bladder lesions: bladder volume is small, the source of the bladder, tethered cord, bladder dysfunction, contraction, etc. will always meet. Physical examination should be clear spine sacral shape, lower limb nervous system and anal sphincter function. Sometimes require further examination, B ultrasound, cystography, urodynamics and even MRI of the spinal cord. Urodynamic examination becomes very important. Some children have over-active bladder, which can be controlled by some medicine. A lot of time after a self-healing. 

4. End stage renal failure: these children are usually old patients with a clear diagnosis. Kidney lost the function of concentration, urine amount increased, causing urinary frequency. Need dialysis or kidney transplant.

The above is the relevant content about the causes of frequency of urination in children, we hope to help you. Parents in daily life must pay attention to the child's health. Children's immunity is relatively low, it is vulnerable to disease.
