Diagnosis of Acute Obstructive Renal Failure by Clinical Ultrasound Performed by the Emergency Physician.

Acute renal failure is frequently diagnosed in the emergency room during a biological assessment. Its discovery requires determining the cause, which may be either functional, or obstructive. The obstructive cause is responsible for 10% of acute renal failure. It is recommended to start the exploration of this pathology with an ultrasound in search of an obstructive cause. However, ultrasound from the radiologist is not always available. The realization of this ultrasound by the emergency physician would reduce the time to obtain the diagnosis and therefore the time of passage to the emergency room. No study has yet been carried out to validate the performance of this ultrasound by the emergency physician in the case of acute renal failure. This study would validate the diagnostic performance of this ultrasound technique in order to identify as quickly as possible patients with acute renal failure whose cause is obstructive.
