Background: Urinalysis can be helpful in the diagnostic workup of acute abdominal pain. Aim: To assess the value of urinalysis in the differential diagnosis of acute abdominal pain. Material and Methods: Retrospective analysis of patients consulting in the emergency room for acute abdominal pain in whom an urinalysis was performed. The concordance between the diagnosis of the causes of abdominal pain and alterations in the urinalysis was evaluated. Results: An urinalysis was requested to 88 males and 247 females of 1106 patients consulting for acute abdominal pain. The test was informed as normal in 62% of patients, as bacterial contamination in 15%, as urinary infection in 14% and as hematuria in 9%. The concordance between the presumptive diagnosis of the cause of abdominal pain made on admission and the diagnosis at discharge had a Kappa of 0.64. However the concordance between the diagnosis suggested by the urinalysis and the discharge diagnosis was low (Kappa= 0.39). Conclusions: In this series of patients with acute abdominal pain, a low concordance between the discharge diagnosis and the diagnosis suggested by the urinalysis, was observed
