What are the symptoms of prostate hyperplasia?

Once prostate hyperplasia occurs, people will often feel abnormalities in their bodies, but the symptoms of this disease are not very obvious, unless they find it difficult to urinate when going to the toilet, accompanied by a series of symptoms such as frequent urination and urgency. These are relatively typical symptoms, most of which only appear in the early stages of the disease. Severe patients will experience urinary tract obstruction.

In the early stage of prostatic hyperplasia, the symptoms are atypical due to compensation. As the lower urinary tract obstruction worsens, the symptoms gradually become more obvious. The clinical symptoms include symptoms during the urine storage period, symptoms during the urination period, and symptoms after urination. Due to the slow progression of the disease, it is difficult to determine the onset time.

1. Symptoms of urinary retention

The main symptoms of this stage include frequent urination, urgency, urinary incontinence and increased nocturia.

(1) Frequent urination and increased nocturia Frequent urination is an early symptom. The frequency of nocturia increases, but the amount of urine each time is small. After the bladder detrusor fails to compensate, chronic urinary retention occurs, the effective capacity of the bladder is reduced, and the interval between urination is shortened. If accompanied by bladder stones or infection, the frequent urination becomes more obvious and is accompanied by pain during urination.

(2) Urinary urgency and urinary incontinence When lower urinary tract obstruction occurs, 50% to 80% of patients experience urinary urgency or urge incontinence.

2. Symptoms during urination

Symptoms of this stage include hesitancy, difficulty urinating, and intermittent urination.

As the gland enlarges, mechanical obstruction worsens, urination becomes more difficult, and the degree of lower urinary tract obstruction is not proportional to the size of the gland. Due to increased urethral resistance, the patient's urination starts late, urination time is prolonged, the range is not far, and the urine stream is thin and weak. The urine is forked, and there is a feeling of incomplete urination. If the obstruction worsens, the patient must increase abdominal pressure to help urination. Breathing causes abdominal pressure to increase or decrease, resulting in interrupted and dripping urine flow.

3. Post-urination symptoms

Symptoms of this stage include incomplete urination and dribbling after urination.

Incomplete urination and increased residual urine: Residual urine is the result of bladder detrusor failure to compensate. When the residual urine volume is large, the bladder is over-inflated and the pressure is very high, which is higher than the urethral resistance, urine overflows from the urethra by itself, which is called overflow incontinence. Some patients usually do not have much residual urine, but when they are cold, drink alcohol, hold urine, take medicine or have other reasons that cause sympathetic nerve excitement, acute urinary retention may suddenly occur. The symptoms of urinary retention in patients may be better or worse. Some patients may have acute urinary retention as the first symptom.
