Analysis the Relationship Between the Abdomen CT and Outcomes in Acute Urinary Stone Patients

Study Overview
=================
Brief Summary
-----------------
This is an observational study based on retrospectively collected data of ureter stone patients between 2011 and 2014. Aim of study is to determine radiologic findings of non-contrast abdominal computerized tomography as predicting clinical outcomes of suspect ureter stone patients in emergency department (ED).

Detailed Description
-----------------
Gennerally, non-contrast abdominal computerized tomography is a choice of diagnosis for a ureter stone patient.There was no known well of efficacy of CT for predicting the outcomes in ureter stone patient in ED. Hypothesis of this study are some findings of non-contrast CT may be helpful to predict the clinical outcomes of pain severity (multidose of painkiller), admission and revisit to ED within 5 days after discharge. Investigators analyzed multiple variables including age, sex, initial clinical findings, and various CT findings to assess their association with outcomes; multidose of painkiller in ED, admission at ED and revisit to ED within 5 days.
