Brief summary: The management of renal colic in emergency departments follows the recommendations established at the 8th consensus conference of 2008 on the management of renal colic in emergency services. It recommends the control of pain by nonsteroidal anti-inflammatory drugs and analgesics, the implementation of an urinary test strip and the use of emergency imaging for compiled forms and patient with medical specificities.

Currently, two imaging techniques are recommended during an episode of renal colic:

1. Abdominal x-ray/Ultrasound or non-injected scanner for simple forms to be performed within 24-48h
2. The non-injected scanner for complicated forms In simple forms, the decision to perform any examination remains at the discretion of the physician but with a tendency to carry out a scanner systematically even in the absence of criteria of severity or complication.

The use of the scanner exposes the patient to large doses of radiation even if it is a low dose scanner.

In recent years, studies have been conducted to determine whether the ultrasound, particularly "point of care" ultrasound performed by an emergency physician could be an alternative in the management of renal colic. Studies show that the sensitivity and specificity of ultrasound is comparable to that of the scanner. It has been found that the performance of an ultrasound by the emergency physician allows the decrease in irradiation and also in costs. In 2014,a study published in the New England Journal of Medicine emphasized that the ultrasound performed by the emergency physician would perform just as well as that performed by the radiologist and would result in a decreased time in the emergency room.

The Korean study, published in 2016 in the Clinical and Experimental Emergency Medicine (CEEM), despite some statistical inconsistencies, shows a significant reduction in the time of care by 74 minutes. In this context, we would like to conduct a single-centre, randomised, controlled, open-label study comparing a group of patients benefiting from point of care ultrasound versus a group of patients not benefiting from it. The goal is to determine whether the early ultrasound performed by the emergency physician by detecting expansions of the pelvicalyceal cavities reduces the time spent in the emergency department.
