The first thing we need to understand is that BPH is a progressive disease that gets progressively worse as older men get older. This means that if we do not intervene in the pathogenesis of BPH or if we only treat it for a short period of time, then we will not be able to fundamentally stop the progression of BPH. It is because benign prostatic hyperplasia is an old age disease that develops gradually with age, so the focus of treatment is not to solve the momentary pain, but to receive long-term systematic and standardized treatment so as to slow down the rate of prostatic hyperplasia and prevent various complications, such as acute urinary retention. The actual fact is that there are many drugs used to treat BPH, and each one has its own advantages, such as alpha-blockers that can quickly improve urinary symptoms. The only drug that really targets the cause of BPH is a 5 alpha-reductase inhibitor (finasteride, trade name: Paulownia). Numerous studies have shown that long-term use (1 tablet per day) of finasteride can reduce the incidence of acute urinary retention and the risk of prostate-related surgery. In addition, finasteride is the only drug known to reduce the size of the prostate. If you can take finasteride for a long time at the beginning of the disease, you can avoid acute urinary retention later. I would like to conclude by saying that I sincerely hope that all patients with BPH will embrace the concept of long-term medication under the guidance of a professional physician to achieve good results.
