Interruption of urine flow

Introduction Interrupted urine flow refers to a sudden interruption of urine flow during urination, sometimes accompanied by severe pain in the head of the penis. The most common cause is that patients with benign prostatic hyperplasia must increase their abdominal muscles to drain their urine. In the late stage of the disease, the urine can not be drained at one time, and it takes a breath to continue to urinate, which is manifested as interruption of the urine flow. Patients with bladder stones, bladder tumors, bladder foreign bodies, ureteral cysts and other diseases during the urination process, stones, tumors or ureteral cysts, foreign bodies, etc. can continue to urinate after moving with the urine flow. During the urination of patients with giant bladder diverticulum, vesicoureteral reflux, and ureteral effusion, although most of the urine has been excreted, a significant portion of the urine is still in the diverticulum or ureter. After the end of urination, this part of the urine quickly enters the bladder again, and produces urine, and urinates again. This condition is called two-stage urination, not interruption of urine flow.

Cause

The pattern of urination should be normal in the shape of a bell, smoothing up to the maximum urinary flow rate, and smoothing out. Because of the difficulty of urinating, sometimes it will be interrupted, the figure will be fluctuating, some people will use the abdomen to force, and the shape also sees jagged, which can provide doctors' diagnosis.

First, suffering from urethritis or cystitis, due to urinary stimulation, bladder contraction, to prevent continued urination.

Second, suffering from bladder stones, tumors or blood clots, will also interrupt the flow of urine.

Third, suffering from benign prostatic hyperplasia or incomplete obstruction of the urethra, the bladder muscles are overpowered, and half of the solution will not work.

Symptoms of prostate hyperplasia:

1, increased urine: urinary frequency is an early symptom of benign prostatic hyperplasia, normal people usually urinate more often: 3 to 4 times during the day, 1-2 times at night. If there are more frequent urinations, staying up all night, especially the number of nocturia, it should be thought that the prostate may be oppressed. Every time you urinate, you can not completely drain the urine stored in the bladder, which is equivalent to reducing the volume of the bladder. It makes the urineiness less frequent, and the urination time and interval are gradually shortened.

2, urine waiting: urine waiting for the urine, early urine, and set the posture of urination, but can not immediately urinate, must wait for a while before the urine slowly discharged.

3, urination weakness: sincere urination has a certain impact, urine flow is parabolic, there is a certain speed and range. Ineffective urination is due to prostate hyperplasia oppressed the urethra of the prostate segment, making the urine flow thinner, the shape is not parabolic, the range is also short, and sometimes the drip is down, there is a situation of "urinary wet shoes". 4, urinary incontinence: urinary incontinence refers to out of control at night. Urinary incontinence is due to the increase of residual urine in the bladder. The pressure in the bladder gradually increases after falling asleep. If the resistance of the urethral lumen is exceeded, the urine will overflow spontaneously. In severe cases, it cannot be controlled during the day.

5, urinary pain in urgency: due to urinary night exhaustion, increased urinary frequency, etc., easy to cause bacterial infection, urinary tract infection, urgency caused by inflammation, urinary pain, so-called urgency, refers to After the urine, I can't wait to urinate immediately, and I will pee in the crotch later.

6, interruption of urinary flow: urinary interruption is the sudden urination of urine when urinating. Prostatic hyperplasia, obstruction of the posterior urethra, increased resistance during urinary excretion, excessive contraction of the bladder detrusor to drain the urine in the bladder. To this end, the patient must increase abdominal pressure to help urinate; due to respiratory reasons, abdominal pressure changes with changes in breathing, followed by a stream of urine.

In addition, the elderly suddenly interrupted during urination. Due to prostatic hyperplasia, the accumulation of urine in the bladder increased, and many crystals in the urine formed stones. In the middle of urination, stones suddenly blocked at the bladder outlet, making urine The liquid suddenly broke. There is no need to be nervous at this time, so that the body can lean back and sit better. The purpose of this is to raise the position of the bladder mouth, and the stone moves to the lower part of the bladder mouth, and the urination is smooth again. This is also the method of diagnosing bladder stones.

7, hematuria: prostatic hyperplasia, capillary mucosal congestion on the prostate mucosa, dilatation, when urinating, bladder contraction, causing hematuria, occasionally a large amount of bleeding can occur.

8, acute urinary retention: one of the common symptoms of benign prostatic hyperplasia. Due to sudden changes in climate, fatigue, alcohol, sexual intercourse, acute urinary tract infections, etc., the gland and the clogging function of the neck are congested and edema, resulting in acute obstruction, interrupting urination and causing urinary retention.

Differential diagnosis

The diagnosis should be differentiated from the following symptoms:

1. The urine flow becomes thinner or interrupts the acute prostatitis. Urinary tract symptoms: burning pain during urination, urgency, frequent urination, urine drip and purulent urethral secretions. Bladder neck edema can cause poor urination, fine or interrupted urinary flow, and severe urinary retention.

2. Slow urine flow The reason why women are susceptible to urinary tract infection is mainly because of the special structure of female reproductive system, female vaginal secretion is also a better medium, the use of bacteria is easier to breed, the urine flow is slow to form a mild Caused by effusion and other aspects.

Urinary tract infection, also known as urinary tract infection, refers to the urinary tract inflammation caused by pathogens growing in the urinary tract of the body and invading the mucosa or tissues of the urinary tract. Bacteria are the most common pathogens, and fungi, viruses, parasites, etc. can also cause infection.

3. The urinary flow is a fluctuating abdominal aortic aneurysm, which is an arterial dilatation disease and is the most common type of aneurysm. In recent years, the incidence of abdominal aortic aneurysms in China has shown an upward trend. Statistics show that among elderly people over the age of 65, the incidence of abdominal aortic aneurysm is about 8.8%. Moreover, many patients have sudden aneurysm rupture without any symptoms, and the mortality rate of patients with such tumor rupture can reach more than 90%. Therefore, the medical community also refers to the abdominal aortic aneurysm as a "time bomb" in the human body.

Most patients with abdominal aortic aneurysm have no symptoms and are often referred to as a quiet abdominal aortic aneurysm when performing routine physical examination. With the development of regular physical examinations, it has been found that this type of aneurysm is also gradually increasing in symptomatic patients. The common symptoms are abdominal pulsating masses, followed by dull pain in the umbilical or upper abdomen or only abdominal discomfort. When the aneurysm invades the lumbar vertebrae, there may be pain in the lumbosacral region. Sometimes the aneurysm may enlarge or even penetrate into the duodenum or jejunum, thereby producing gastrointestinal bleeding. In addition, the enlargement of the tumor may produce some compression symptoms such as compression of the gallbladder. The general canal has jaundice; oppression of the duodenum causes intestinal obstruction; compression of the ureter causes renal colic or hematuria; when the bladder is compressed, there may be frequent urination and fluctuations in urine flow.
