When a child is being evaluated for bed-wetting, a physical exam is usually done to see whether medical conditions or sexual abuse may be causing the bed-wetting. During the physical exam, the doctor will examine the child's:
As part of the physical exam, your doctor may ask the child to hold his or her urine as long as possible and then urinate into a container. The doctor can use the sample of urine to estimate the amount of urine that the bladder can hold (bladder capacity) at one time. Normal bladder capacity (in ounces) can be estimated by adding 2 to the child's age. For example, a 6-year-old can hold about 8 fl oz (236.6 mL) of urine at one time.
The doctor also may watch the child urinate to look for a weak urine stream, which may be a sign of a block in the urinary tract.
