Hydronephrosis
Hydronephrosis is usually diagnosed using an ultrasound scan. Further tests may be needed to find out the cause of the condition.
An Ultrasound scan uses sound waves to create a picture of the inside of your kidneys. If your kidneys are swollen,this should show up clearly.
You mayneed a number of additional tests to help determine the cause of hydronephrosis. These may include:
Hydronephrosis may be diagnosed in your babywhile you'repregnant, usually during a routine pregnancy ultrasound scan at around 20 weeks. This is known as antenatal hydronephrosis.
If your baby is diagnosed with antenatal hydronephrosis, you may need to have extra ultrasound scans during your pregnancy to check your babyisgrowing normally and their kidneys are not getting too large.
In most cases, the problem will improve before your baby is born or within a few months afterwards. Your baby may need to have scans after they're born to monitor their condition and see if treatment is necessary.
