The predictor analysis of response to routine treatment in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia.
OBJECTIVE: This study tried to test predictors of response to routine treatment in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH).
METHODS: Subjects were evaluated at baseline and at week 12 following routine treatment for LUTS/BPH using the Korean version of the International Prostate Symptom Score (IPSS) to measure the severity of LUTS/BPH. Demographics and various clinical variables were analyzed by regression analysis.
RESULTS: Ninety three patients received routine treatment for LUTS/BPH for 12 weeks in a naturalistic treatment setting. None of demographics and clinical variables was different between responders and non-responders. According to multivariate regression analysis, the presence of anxiety (OR=0.203), lower improvement in the GAD-7 total score (OR=0.755) and lower improvement in the PHQ-15 total score (OR=0.811) were independent predictors of treatment response after 12 weeks routine treatment.
CONCLUSIONS: We found the positive association of improvement in anxiety and somatization with treatment response, while presence of anxiety was negatively associated with treatment response, in patients with LUTS/BPH. However, additional studies with adequate power and improved designs are necessary to support the present findings....
