Towards evidence based emergency medicine: best BETs from the Manchester Royal Infirmary. Investigating microscopic haematuria in blunt abdominal trauma.

A short cut review was carried out to establish whether it is necessary to carry out further imaging in order to identify clinically significant renal injury in patients with microscopic haematuria after blunt abdominal trauma. Altogether 57 papers were found using the reported search, of which 10 presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. A clinical bottom line is stated.
