If you have any of the following symptoms, contact your doctor:

• A decrease in the amount of urine you produce

When your condition is stable, your doctor will perform a physical examination and ask questions, such as:

• When did you first notice symptoms?
• What symptoms did you notice?

• Kidney or abdominal CT scan
• Kidney or abdominal ultrasound
