Prostatic hyperplasia is one of the most common urological diseases in elderly men. The pathological characteristics of the enlarged prostate tissue are mainly an increase in the stroma of the enlarged glandular tissue, which often causes symptoms of mechanical obstruction in the lower urinary tract, and also causes an increase in the tension of the smooth muscle in the prostate area, which causes difficulty in urination, resulting in various degrees of difficulty in urination, causing a series of lesions in the bladder and kidneys, such as If not timely and reasonable treatment. Eventually it will lead to renal function damage. The severity of clinical symptoms does not necessarily correlate with the size of the prostate enlargement. The typical clinical manifestations of prostate enlargement are often described as follows: 1. The frequency of urination is an early symptom, especially at night, which is most obvious, called “nocturnal urination”. If there is residual urine, it is easy to induce urinary tract infection and stone formation, which can intensify the frequency of urination, and there may be further urinary urgency and even urge incontinence. 2.People with difficulty in urination, waiting for urine, thin urine line. If the obstruction is aggravated, the abdominal pressure needs to be increased to help urination, and there is interruption of urine flow and dripping after urination. When the amount of residual urine is large, filling incontinence and nocturnal “urine loss” may occur. Acute urinary retention can occur when the patient is cold, fever, holding urine, drinking alcohol, emotional changes and other causes of sympathetic excitation. 4, prostatic hyperplasia if not treated in a timely manner, long-term hydronephrosis, abnormal kidney function will cause loss of appetite, nausea, vomiting, anemia and other uremic symptoms. 5, some patients due to long-term increase in abdominal pressure, can cause hemorrhoids, prolapse and hernia and other diseases. 6, long-term urinary retention can also cause bladder stones and increased incidence of urinary tract infections.
