Signs and tests:

An examination may indicate disorders that occur as a consequence of nephrocalcinosis. For example, it may be discovered when symptoms of renal insufficiency, kidney failure, obstructive uropathy, or urinary tract stones develop.

There may be signs of fluid overload, such as abnormal heart and lung sounds, if kidney function is poor.

Imaging tests can help diagnose this condition. Tests that may be done include:

• Abdominal CT scan
• Abdominal film

Other tests may be done to diagnose and determine the severity of associated disorders.
