The Factors that Influence the Clinical Outcomes after Trial without Catheter for Acute Urinary Retention due to Benign Prostatic Hyperplasia: a Multicenter Trial / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Benign prostatic hyperplasia (BPH) is a common problem that's experienced by aging men, and it can lead to serious outcomes, including acute urinary retention (AUR). We studied the factors that influence the clinical outcomes after trial without catheter (TWOC) for AUR due to BPH. MATERIALS AND METHODS: The medical records of all 455 BPH patients who visited the emergency room for the first time with AUR from March 2001 through February 2005 were retrospectively reviewed. The patients were divided into two groups: the success group (group I) or failure group (group II) that underwent trial without catheter. The patient's characteristics were compared between the two groups using logistic regression analysis and the chi-square test. RESULTS: From the 292 cases of group I and the 163 cases of group II, the multivariate analysis revealed statistically significant differences in the retention volume (p<0.01), the prostate volume (p<0.01) and the previous use of alpha-blockers before AUR (p<0.01). CONCLUSIONS: The prostate volume, retention volume and previous use of alpha-blockers before AUR were thought to influence the clinical outcomes of TWOC for the BPH patients with AUR, and these factors should be considered in future treatment planning.
