Pain in the bladder area before and after urination

Introduction Bladder pain before and after urination is a common symptom of cystitis. Cystitis is a common urinary tract infection, accounting for about 50% to 70% of the total number of urinary tract infections. Caused by bacterial infection. Most of the pathogenic bacteria are Escherichia coli. It usually occurs in women because the female urethra is shorter than the male urethra and close to the anus. E. coli is easy to invade. The most typical symptoms of cystitis are frequent urination, urgency, dysuria, and even urinary incontinence. There may be hematuria and pyuria.

Cause

There are many causes of cystitis, but most of them are infections of pyogenic bacteria. The causes are stones, foreign bodies, tumors or obstructive lesions, including dysuria due to neurological disorders. Pathological changes in acute inflammation of cystitis include mucosal congestion, edema, hemorrhage and ulcer formation, and pus or necrotic tissue. Chronic inflammation mainly includes mucosal hyperplasia or atrophy, granulation tissue formation, fibrous tissue hyperplasia, decreased bladder capacity, or muscle hypertrophy caused by concurrent obstruction, increased bladder capacity and even diverticulum formation. Another special inflammatory change is gangrenous cystitis, which is a serious bladder inflammation caused by Clostridium, Clostridium perfringens and the like.

1. Urinary tract angiography: Chronic cystitis shows a reduction in bladder volume and a rough or irregular bladder edge.

2. B super performance: the bladder cavity is reduced, the bladder wall is generally thickened.

3. CT manifestations: Chronic cystitis manifested as extensive irregular thickening of the bladder wall, shrinkage of the bladder and uneven internal and external margins. Urinary cystitis also showed intravesical gas and inflammatory effusion in the pelvis.

4. MR performance: the thickening of the bladder wall is often not smooth, the signal is uneven, and the signal is mainly low.

Differential diagnosis

Urinary syncope: also known as urinating, known as "urinary halo." The main manifestation is that people suddenly fainted when they wake up at night or in the morning due to a brief loss of consciousness; there is always a short-term disturbance of consciousness, which is easy to induce urinary syncope. Mainly due to vasodilation and contraction disorders caused by hypotension, caused by a lack of brain blood supply, the patient can wake up two minutes after the occurrence of syncope, leaving no sequelae. Urinary syncope is more common in middle-aged and older men. It usually occurs at night and often happens suddenly. There is no warning before.

Vulvar burning, itching or pain during urination: acute vulvitis can be seen swelling, congestion, erosion, sometimes forming ulcers or pieces of eczema. The patient feels burning, itching or pain in the genital area, especially during urination. Severe inguinal lymph nodes, tenderness, body temperature can be slightly elevated, leukocytosis. Diabetic vulvitis, the vulva skin is red, thick, often brown, with scratches. Because urine sugar is conducive to mold growth and reproduction, it is often associated with Candida albicans infection. In the case of chronic inflammation, the vulva is itchy and mossy.

Pain in urination: In men, in addition to painful urination, the flow of urine appears to be small, the strength of urine is also weak, and sometimes even scattered, it may be that the urine is in the process of outflow This kind of obstacle is mostly caused by the enlarged prostate. However, it may also be one of the causes of urinary pain caused by the numbness of the muscles that control the bladder function.

Foreign body sensation of urination: It is because a patient with urinary calculi feels a foreign body sensation when urinating. Urinary calculi are rare in clinical practice. Most are derived from the urinary system above the bladder and bladder, such as kidney stones, ureteral stones or bladder stones. Stones can stay in the urethra or invade the urethra, scaphoid or urethra of the prostate when discharged. A small number of secondary to urethral stricture, urethral atresia, foreign body or urethral diverticulum. Stones that originate in the urethra are quite rare. Usually a single stone. Most of the stones in the combined infection are ammonium magnesium phosphate. Most female urethra stones occur in the urethral fistula.
