Purpose:
To investigate the long-term therapeutic effects, patient adherence of combination therapyof 5-α-reductase inhibitor (5ARI) and alpha-blocker, and the predictors for withdrawal of medication in patients with clinical benign prostatic hyperplasia (BPH).
Materials and Methods:
BPH patients with lower urinary tract symptoms (LUTS) under combination therapy were retrospectively analyzed from 1 to 12 years span. The therapeutics effects were assessed by International Prostatic Symptoms Score (IPSS) and quality of life index (QoL-I), total prostatic volume (TPV), maximum flow rate (Qmax), voided volume (VoL), prostatic specific antigen (PSA) at baseline and annually. The reason and predictors of discontinued combination therapy were also investigated.
Results:
A total of 625 patients aged 38 to 97 (mean 73) years where enrolled retrospectively with at least 1 year and the longest period of 12 years follow-up. The mean year follow up was 3 years. All measured parameters showed significant improvement after combination therapy. The mean year of discontinuation of combination therapy was 2 years.  Whereby, the most common reason for discontinuation of combination therapy was converting to single medication (19.8%). Age did not influence the adherence rate (p < 0.484), but the QoL-I was a predictor to adherence of combined therapy. (p=0.000)
Conclusion:
The patient received combination therapy showed significant improvement in all the measured parameter. The most common factor of discontinuation of combination therapy was converting to single medication.  QoL-I after treatment lead patient adheres to combination therapy.
