Symptoms of prostatic hyperplasia appear gradually with the development of prostate enlargement. In the early stages, symptoms are not obvious due to functional bladder compensation, and various symptoms appear as the disease worsens. The main clinical manifestations are bladder irritation symptoms and obstruction symptoms. Bladder irritation symptoms include urinary urgency, frequency, nocturia and urge incontinence. The instability of the detrusor muscle is the main cause of bladder irritation symptoms. Symptoms of obstruction include hesitation and effort to urinate, prolonged urination time, thinning of the urine line, weak urine flow, intermittent urination, urinary retention and urge incontinence. 1, urinary frequency: the most common symptom of early prostate enlargement is frequent urination, and gradually aggravated, especially the increase in the number of night urination. The cause of frequent urination is caused by congestion and stimulation of the bladder neck in the early stages, and in the later stages by obstruction of the urethra caused by the enlarged prostate, which increases the residual urine in the bladder and reduces the effective capacity of the bladder. In addition, the obstruction induces changes in the function of the bladder forcing muscle, reduced bladder compliance and instability of the bladder forcing muscle to make urinary frequency more pronounced. 2.Progressive dyspareunia: The main manifestations are slow onset of urination, intermittent urination, short range, thin urine line, terminal dribbling, effortful urination, segmental urination and incomplete urination. 3. Urinary incontinence: The amount of residual urine in the bladder is increasing in advanced prostate hyperplasia. When a large amount of residual urine accumulates in the bladder, due to overfilling and expansion of the bladder, the pressure in the bladder increases to exceed the urethral resistance and then urine can overflow on its own at any time, called filling incontinence. 4, acute urinary retention: on the basis of difficulty in urination, acute urinary retention can occur if there are cold, alcohol, exertion and other triggers that cause congestion and edema in the gland and bladder neck. The patient’s bladder is extremely swollen, the lower abdomen is distended and painful, the urge to urinate is frequent but the urine cannot be discharged, and the patient is restless and has difficulty sleeping. 5, hematuria: prostate enlargement tissue surface often has venous expansion of congestion, rupture can cause varying degrees of painless corporeal hematuria. The amount of hemorrhage varies, mostly intermittent, and occasionally large amounts of bleeding and clots fill the bladder, requiring emergency treatment. The hematuria caused by prostatic hyperplasia should be differentiated from that caused by inflammation, stones and tumors in the bladder. 6, renal insufficiency symptoms: late due to long-term urinary tract obstruction and the two kidney function decreases and chronic renal insufficiency, manifested as loss of appetite, nausea, vomiting and anemia, etc. 7, other symptoms: due to long-term urinary difficulties and lead to increased abdominal pressure, can cause or aggravate hemorrhoids, prolapse and hernia, etc.
