Renal colic (RC) are a frequent cause of consultation in the emergency departement (ED). It counts for approximatively 20 % of patients presenting to the ED with severe acute onset abdominal pain.~The first line treatment of renal colics is based on NSAI drugs associated with antalgics and is further investigated in the NSAI vs Morphine study (NCT02156596) But there is no clear recommendations regarding the outpatient treatment of renal colics. Oral NSAI are still widely used as a second line medicine for this condition and variety of molecules were tried with non solid scientific arguments.~Piroxicam, a non-selective COX inhibitor drug appared to the oxicam class of NSAI, is widely used to treat rhumatoid and inflammatory disesases, and often prescribed in Tunisia as a second line treatment of RC.~In this study, the investigators aimed to investigate the efficiency and safety of the use of oral NSAI drugs (piroxicam) compared to Acetaminophen or placebo as a second line treatment of renal colics
Treatment with NSAI in renal colics has not been well investigated and there is no clear recommendations regarding this subject.~The aim of this study is to determine if an oral NSAI treatment is beneficial in patients discharged for the emergency department after the first line treatment of a renal colic investigating the reccurence of pain, the reconsultation rates and the admissions.
