What causes urethral stenosis?

Many male friends will find that they have difficulty urinating in their daily lives, and even have pain when urinating, and feel pain in the prostate. At this time, it may be male urethral stenosis. This kind of disease usually leads to difficulty urinating.

Causes of urethral stenosis in men

There are three narrow places in the total length of the urethra: the first is at the transition between the renal pelvis and the urethra; the second is at the place where the iliac vessels pass through the upper opening of the pelvis; and the third is at the place where the bladder wall is penetrated. These three narrow places are often where stones stay.

The male urethra has three narrow parts, located at the internal urethral opening, the membranous urethra and the external urethra, with the external urethral opening being the narrower.

The male urethra has two bends: the inferior bend of the phalanges is located directly below the ischial tuberosity, concave forward and upward, and this bend is stable and will not change. The anterior bend of the phalanges is located in front and below the ischial tuberosity, concave backward, and if the male genitals are lifted up, this bend will be straightened.

If you have any discomfort, you should

In the article, we learned about male urethral stenosis. There are many causes of this disease. In daily life, we should pay more attention to it, especially many conditions should not be ignored, and we should also pay attention to our daily diet.

Symptoms of urethral stricture

Male urethral stenosis is a common disease of the urogenital system and a key cause of male infertility. There are many causes of male urethral stenosis, and the clinical symptoms of male urethral stenosis are also different.

1. Difficult urination

Difficulty in urination is the most critical symptom of urethral stenosis. It can be mild or frequent and is related to the degree of urethral stenosis.

2. Bladder irritation and bladder loss compensation

The main symptoms are frequent and urgent urination, inability to hold urine, continuous urination, and gradually leftover urine, and finally urinary retention or overflow incontinence.

General physical examination:

Blood pressure urethral orifice palpation: in case of anterior urethral stenosis, the narrow area can be palpated, and attention should be paid to its length, whether there is tenderness, and the contents and characteristics of the urethral orifice.

Blood rectal examination, pay attention to the male prostate and posterior urethra. If there is a supraphalangeal cystostomy, a urethral probe can be inserted through the stoma into the bladder neck and into the posterior urethra to help identify the proximal part of the urethral stenosis.

Supplementary urethral opening probe examination can clarify the location, length and level of the narrow.

The most common symptoms of patients with urethral stenosis are obstructive urination or urinary tract infection (such as prostatitis, epididymitis). Some patients will experience urinary retention. If you look carefully, most patients have long-term symptoms of urinary incontinence before developing a trend towards complete obstruction. The diagnosis of urethral stenosis can be confirmed based on medical history, clinical symptoms and physical examination alone, but it is necessary to determine the location, length, level of the stenosis, and whether there are false passages, diverticula, stones, fistulas and relative density (penile corpus cavernosum fibrosis process).

Type:

Urethral strictures can be divided into cataract and organic; the latter includes both congenital and acquired types.

1. Transurethral stenosis

It is a temporary condition caused by the contraction of the external expansion of the urethra. The cause can be urethritis, urethral stones, the use of instruments in the urethra or sexual abnormalities, etc. Sometimes it can also be caused by reflex stimulation of the perineum, duodenum and pelvis, or completely due to psychological factors. The urethra muscles are spasmed in the membranous part, so it is inseparable from the narrowness of the bulb and membranous organs. When a blunt-tipped instrument encounters obstruction in the urethra (such as a catheter, ureteroscope), it can continue to apply light working pressure.

If urethral stenosis is caused by spasm, the urethral opening often releases pressure suddenly and allows the device to pass through. Under anesthesia, urethral stenosis can be completely relaxed without causing obstruction. Bladder urethral opening radiography is very helpful for diagnosis. Comprehensive treatment is used for urethral stenosis, including eliminating the cause of the disease, hot water sitz bath, sedatives, analgesics and anticonvulsants, etc. Acupuncture can be used when the bladder is overfilled, and catheterization can be used when necessary.

2. Small Organs

In clinical medicine, paroxysmal seizures are more common.

1. Congenital microsomia

It is common in cases of narrow urethral opening, often accompanied by long foreskin or prepuce is too long, epispadias or hypospadias urethral opening is often narrower than normal, the anterior urethral heart valve often has a double-chamber anterior urethra malformation with the septal heart valve, and then the urethral heart valve often has a small round hole in the center, urine drips, and narrow urethral opening is often seen at the junction of the bulb and the membrane and the rear end of the fossa navicularis.

2. Acquired narrowness

According to the cause, urethral stenosis can be divided into traumatic stenosis and inflammatory stenosis. Trauma is the most common cause of urethral stenosis, which is often seen in perineal riding injuries, pelvic fractures causing membranous urethral injuries, and urethral oral injuries caused by actual equipment operations. When the urethral opening is severely injured and the submucosal and wall layers are invaded, the urethral opening muscles are
