The Factors that Influence the Success Rate of Treatment without Using a Catheter for the Management of Acute Urinary Retention: Comparison

Purpose: Acute urinary retention (AUR) is a serious outcome of benign prostatic hyperplasia (BPH). Although Foley indwelling catheterization is a standard treatment for the conservative management of AUR, we studied the success rate of in-and-out catheterization and the factors that favor a positive outcome of a trial treatment without using a catheter (TWOC). Materials and Methods: We retrospectively reviewed the medical record of all 127 patients who admitted as emergency cases with primary AUR caused by BPH (from January 2002 to August 2005), and these patients underwent in-and-out catheterization or Foley indwelling catheterization and then they underwent TWOC 1 week later after the first treatment. The patients were divided into four groups: the success group (group I) or failure group (group II) that underwent in-and-out catheterization and the success group (group III) or failure group (group IV) that underwent TWOC. The factors that might influence the outcomes were assessed using logistic regression analysis and Student's t-test
