Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Acute water load test has been using to diagnose renal ability to excrete water for decades. Latest recommendations for the diagnosis of hyponatremia do not recommend performing such a test. The investigators aim at, retrospectively, study the value of acute water load test in patients suffering from a syndrome of inappropriate antidiuresis.

Water load test

Patients experiencing a syndrome of inappropriate antidiuresis who had an acute water load test

Acute water load test

Intervention Type PROCEDURE

The acute water load test consists in administering orally 20 mL/kg (of body weight) of water (ingested in less than 30 min) and then follow (during 4 to 6 hours) blood and urine parameters.

Control group

Patients who had an acute water load test and who did not experience any water homeostasis anomalies
