For elderly men, the first thing to do is to be alert to prostate enlargement, which if ignored may cause serious complications such as bladder dysfunction, hydronephrosis, renal insufficiency, recurrent urinary tract infections and hematuria. Prostate enlargement is commonly known as prostate enlargement. Men begin to experience histological enlargement of the prostate gland from the age of 45, and symptoms of prostate enlargement begin to appear after the age of 50. If the degree is mild, there may be no obvious symptoms. If the degree increases, symptoms such as waiting to urinate, weak urine line, thin urine line, incomplete urination, frequent urination, urgent urination and painful urination may occur, and if left untreated, complications such as urinary retention, urinary incontinence, hematuria, bladder stones and renal insufficiency may occur, sometimes with life-threatening consequences. Bedwetting, or nocturnal enuresis, is a manifestation of overflow incontinence at night, and may occur during the day when the degree of incontinence increases, resulting in reduced social activities and increased psychological stress, which can have a significant impact on quality of life.
