As a man enters his dotage, his prostate usually begins to enlarge. The normal prostate is the size of a chestnut and can enlarge to the size of an egg, duck egg, goose egg, and in some cases, the enlarged prostate can even be the size of a grapefruit, which severely compresses the urethra and blocks the passage of urine flow, which is known as benign prostatic hyperplasia (BPH). The size of the prostate is age-related. According to a clinical study, the volume of the prostate increased by 0.6 ml per year between the ages of 40 and 79, and after 20 years the volume of the prostate increased by 12 ml. If a person’s original prostate volume was 20 ml, after 20 years their prostate volume would be 32 ml. The incidence of benign prostatic hyperplasia (BPH) increases progressively with age. ≥50% over the age of 60 and 80-90% over the age of 80. About 25% of these patients develop urinary tract obstruction and require medication or surgery. According to the International BPH Advisory Committee, BPH is the most common urological disease in middle-aged and elderly men, and its incidence has been increasing year by year with the aging of the population, and its incidence has shown a significant upward trend in recent years. Therefore, the incidence of BPH among middle-aged and elderly people today will be the biggest health problem faced by all countries. BPH and prostate cancer are completely different diseases with no necessary intrinsic connection, i.e. BPH does not become malignant to prostate cancer, but both diseases The two diseases occur in the same age group. BPH can cause people to have a reduced quality of life: for example, when accompanying your wife to the store or going on a trip, always look for a convenient place first in case there is an emergency that cannot be solved in time; there are also too many nighttime wake-ups that affect sleep. Severe BPH can lead to acute urinary retention, incontinence, urinary tract infections, bladder diverticula, bladder stones, hematuria, hydronephrosis, and renal failure. This is the importance of early diagnosis of BPH, which will make it much less likely to produce comorbidities. You should see a doctor immediately if you feel any of the following: increased nighttime urination, urgency, urge incontinence (urinating so urgently that you can’t get to the bathroom in time to pee your pants), a feeling of incomplete urination, having to strain to start urinating, thinning of the urine stream, difficulty urinating, and incoherent urination.
