BPH refers to benign prostatic hyperplasia, which is a common and frequent disease in middle-aged and elderly men. The disease can lead to a series of lower urinary tract symptoms due to the possibility of urinary tract obstruction, so the main clinical symptoms of BPH are frequent urination, urgent urination, increased nocturia, difficulty in urination, and severe prostate enlargement can lead to urinary retention. In terms of treatment, conservative treatment is mainly through oral finasteride as well as tamsulosin treatment. Finasteride prevents the conversion of testosterone to dihydrotestosterone, which in turn reduces the size of the prostate. Tamsulosin is an alpha blocker, which blocks the alpha receptors of the prostate smooth muscle, thus relaxing the prostate smooth muscle and dilating the urethra to reduce the symptoms of dyspareunia. In addition, the surgical treatment is mainly transurethral electrolysis of the prostate.
