When
NDI is first diagnosed, the patient will need to see his doctor frequently (2 to 4 times a year) in order to ensure the medications given help the patient achieve the necessary
fluid balance. After 6 to 8 years, children whose
NDI is in balance, will need to be seen by the doctor once a year. Of course, if the patient isn't growing well or if his
fluid balance isn't being maintained or if the medication isn't working as the patient or his parents expect, then their doctor should be consulted. The patient should also have an
ultrasound for his
bladder every year in order to see whether or not the
bladder has extended beyond its normal form.
