Nephrologist (Kidney Specialist) Questions Urine Problems

My daughter is not passing enough urine. Is this an emergency?

My 2 year old daughter is not passing adequate amounts of urine. Her diaper has only been wet once every day when its usually a few times. She seems to be drinking enough so I am confused. Is this normal or should I get her checked?

She should be evaluated to be sure that there are no problems
Get her checked
Dear Concerned Parent:

I understand that you are worried. A decrease in urine output is the most visible sign of acute kidney injury (AKI) in all age groups, particularly younger children. Oliguria occurs when the urine output in an infant is less than 0.5 mL/kg per hour for 24 hours or is less than 500 mL/1.73 m2 per day in older children. Anuria is defined as absence of any urine output.

However, the first thing is to determine whether it is real. Sometimes children hold their urine. It has happened several times that a parent brought the child to the emergency room for decreased urine output, and then the child had a large void while in the emergency room. The most common reason for decreased urine output is dehydration. Dehydration takes place when your body loses more fluid than you drink. The most common cause of water loss from the body is excessive sweating. There are numerous other reasons why you can dehydrated. These include fever (which increases insensible losses), diarrhea, vomiting, a stomach flu, food poisoning, and rarer conditions. There are a number of other conditions that can cause an AKI. These can only be identified with additional tests.

If you are really worried, I would recommend that you consult a physician.

She should be urinating at least every 12 hours but usually every 4-6 hours if they are drinking enough She could have infection. Some of the diapers are very good at absorbing the urine and she may be urinating some and you not know it. You may want to put some cotton balls inside her diaper to see if she is wetting. I would recommend this getting checked very soon if she is not urinating but once a day
