Causes of difficulty urinating.

Many patients don't know about it. For this problem, the following will give you a detailed introduction.

Causes of difficulty urinating.

Causes of difficulty urinating.

1. Dysuria can be caused by mechanical reasons. Obstructive disease of the bladder below the neck can cause difficulty urinating. The main of these diseases are:

Bladder neck obstruction, prostatic hyperplasia, bladder and urethral stones, tumors of the bladder and urethra, urethral stricture, urethral valves, stones and foreign bodies of the bladder and urethra, obstruction caused by tumor compression of organs adjacent to the bladder, urethral stricture, etc.

2. Dysuria refers to poor urination and laborious urination. The degree of dysuria is related to the condition of the disease. mild cases are characterized by delayed urination and short range; In severe cases, the urine line becomes thinner, the urine flow drips and does not form a line, and it even requires breath-holding and force when urinating, and even needs to press the lower abdomen with your hands to expel urine.

Severe dysuria can progress to urinary retention.

3. Dysuria can also be caused by motility. This includes either neurological dysfunction or bladder detrusor dysfunction. Causes of neurological dysfunction are:

Neuropathic bladder, post-anesthesia, spinal cord diseases (including malformations, injuries, tumors, etc.), complications of advanced diabetes, etc. The causes of bladder detrusor dysfunction include: diabetes, detrusor sphincter dysfunction, etc.

4. The cause of dysuria may be mainly mechanical in the early stage, and motility disorder may appear in the late stage. For example, in prostatic hyperplasia, it can cause dysuria due to obstruction caused by the hyperplasia of the prostate gland in the early stage, and if it is not received in time, it can lead to damage to the detrusor muscle of the bladder in the later stage, causing dynamic dysuria.

Some urinate slowly, the urine stream becomes thinner, and you need to use force; Some are not easy to discharge at the beginning, and it will take a while to solve them; Measured urine flow is not far away; Some people even know that their bladder is full of urine, but they don't feel like they want to urinate. Dysuria often results in residual urethra (urine that remains in the bladder after urinating) and urinary retention (a large amount of urine fluid in the bladder that cannot be excreted). The occurrence of these symptoms is related to the degree and duration of difficulty in urination.

Difficulty urinating is the most common symptom in urology. It can be seen in a variety of urological diseases, the common ones are: 1. Prostatic hyperplasia:

In the more common diseases of elderly men, hyperplasia of prostate tissue compresses the urethra, causing increased urethral pressure, and patients will have labored urination, delayed urination, incomplete urination, urine dripping, and even urinary retention. In the early stages, oral medication can be used for mild cases, and surgery is required for those with more severe symptoms**. 2. Urethral stricture:

Patients often have a history of urethral trauma, which is seen in young men, and the main symptoms are thin urine line, labored urination, and strong urination. Urethral dilation may be indicated in mild cases, while surgery may be required in severe cases**.

There are many common causes of dysuria, which are roughly divided into two categories, one is the functional cause, the functional cause such as the bladder, the nerve innervating the bladder function has problems, resulting in a kind of difficulty in urination, such as cerebrovascular sequelae, cerebral hemorrhage, difficulty in urination after cerebral infarction, as well as some lesions of the spinal cord and some lesions of the lumbar spine that affect the neurological disorders that control urination, resulting in dysuria, which is a functional reason.

Organic causes such as urethral stones, prostatic hyperplasia, prostatitis or prostate cancer, or even tumors in the bladder and urethral orifice can cause difficulty urinating. In addition, urethral strictures, phimosis, etc. can also cause difficulty urinating. There are two main causes of difficulty urinating.

One condition is due to mechanical obstruction of the urethra, such as urethral stones, urethral tumors, urethral rupture, or prostatic hyperplasia, prostate cancer, etc., which are common in men, and cause difficulty in urination. On the other hand, it is necessary to consider a functional cause, such as a decrease or even loss of bladder contractile function due to damage to the nervous system. Taking certain medications that relax the smooth muscles of the bladder, such as atropine, can also cause difficulty urinating.

There are many causes of dysuria, most of which are caused by diseases of the urinary system itself, and systemic diseases and diseases of organs adjacent to the urinary system can also cause dysuria.

What diseases may be associated with dysuria?

Common causes of dysuria can be divided into two categories: mechanical obstruction and dynamic obstruction.

Mechanical obstruction.

Bladder neck obstruction.

The most common cause is prostate lesions, including prostatic hyperplasia.

Fibrosis or tumors.

Wait. Stones in the bladder.

Pedonculated tumors, blood clots, foreign bodies, and adjacent organ lesions (eg, uterine fibroids, pregnancy uterine incarceration, etc.) can also obstruct or compress the bladder neck and cause obstruction.

Urethral obstruction. Inflammation is the most common.

or urethral stricture after injury, urethral stones.

Foreign bodies, tuberculosis.

Tumors, diverticulum, etc. can also cause urethral obstruction, phimosis.

or congenital posterior urethral valves are the main causes of urethral obstruction in infants**.

Dynamic obstruction.

Nerve damage. Head or spinal cord injury.

Wait. Surgical factors.

Central nervous system surgery or extensive pelvic surgery (pelvic plexus injury).

Neurological lesions.

Brain tumor, stroke.

Encephalitis, poliomyelitis.

Tuberculosis of the spinal cord, diabetes.

Multiple sclerosis.

Wait. Congenital malformations.

Spina bifida, meningocele, myelomeningocele, etc.

Since many diseases can cause the symptoms of dysuria, so if there is difficulty urinating, it is necessary to go to the hospital for relevant examinations, according to the medical history and specific examination results, after clarifying the specific ** that causes dysuria, it can be targeted, such as elderly men, the most common cause of dysuria is benign prostatic hyperplasia. If the symptoms of prostatic hyperplasia are mild, drugs such as 1-blockers and 5-reductase inhibitors can be used**.

1 The main effect of receptor blockers is to relax the bladder neck and prostate smooth muscles, reduce urethral resistance, and thus improve the lower urinary tract symptoms of dysuria. The main role of 5-reductase inhibitors is to control the volume of the prostate gland and improve the lower urinary tract symptoms of dysuria. If it is dysuria caused by other diseases, such as urethral stricture, bladder stones, urethral stones, bladder tumors, prostate tumors and other lesions, different methods need to be used**, and some also need surgery** to relieve the symptoms of dysuria.

Dysuria may be caused by prostatic hyperplasia or tumors, most often due to prostate disease.

**Prostatitis hyperplasia, at present, there are not many drugs in this area in China, due to the restrictions on the extraction of drug ingredients in domestic medical technology, the drugs of prostatitis in China can only relieve the symptoms of prostatitis, as an auxiliary, but can not achieve the purpose of prostatitis, which is also the reason why prostatitis in male patients in China is prolonged and difficult to treat. The clinical professional drugs in this area of prostatitis in foreign countries are good Xinxin prostasis tablets, which can completely ** prostatitis; To get men rid of prostate disease, Hao Xin Prostasis Tablets is the first drug for male friends in Europe and the United States to be the first to be on the top of the list for five consecutive years, and it is now on sale in six countries.

Prostatic hyperplasia is a very scary disease because the later stages of prostatic hyperplasia are likely to be urinary poisoning. In the early stage of prostatic hyperplasia, the urethra is mildly obstructed, and the patient can still empty the urine on time due to the compensatory function of the bladder, but the urination time is longer than normal. In the middle stage, the urethral obstruction is aggravated, the urethral resistance increases, and the ability of the bladder to urinate is exceeded, and the patient will have symptoms such as frequent urination and urgency, and the urine in the bladder cannot be completely emptied, resulting in residual urine.

At this time, if you are overtired, cold, or drink alcohol, it will cause edema of the urethral mucosa, which will aggravate the obstruction, and acute urinary retention often occurs. If you can catheter and take medication in time, you can generally still resume urination. In the late stage, the urethral obstruction is severe, the bladder compensatory insufficiency, and the residual urine in the bladder continues to increase, when it exceeds 200 ml, a mass can be felt in the patient's lower abdomen, and the urination is not linear, and it is dripping.

Due to the increased pressure in the bladder, it is transmitted upward to the kidneys, causing increased internal pressure in both kidneys, causing hydronephrosis and impairing kidney function, resulting in chronic urinary poisoning.
