Cystitis
Introduction
Introduction to 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, which usually occurs in women because the female urethra is shorter than the male urethra and close to the anus. Escherichia 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. Treatment first needs to rest in bed, drink plenty of water, avoid irritating food, hot water bath can improve blood circulation in the perineum and relieve symptoms. Alkaline drugs such as sodium bicarbonate or potassium citrate can reduce the acidity of the urine and relieve the bladder spasm. The flavone piperazine (urinary spirit) can relieve the phlegm and relieve the urinary tract irritation. basic knowledge The proportion of illness: 0.36% Susceptible people: mostly occur in women Mode of infection: non-infectious Complications: hydronephrosis, urinary retention, urinary tract infection
Cause
Cause of cystitis
Bacterial infection (35%):
Cystitis has specific and non-specific bacterial infections. The former refers to bladder tuberculosis. Non-specific cystitis is caused by Escherichia coli, E. coli, Proteus, Pseudomonas aeruginosa, Streptococcus faecalis, and Staphylococcus aureus. Infection of pyogenic bacteria. The causes are stones, foreign bodies, tumors or obstructive lesions, including dysuria due to neurological disorders.
Bad habits (30%):
Sexual life is too frequent and unclean sex life, sharing bath towels, smoking and drinking, often eating spicy food, urinating, sedentary and other bad habits lead to urinary tract infection, which causes cystitis. Therefore, maintaining good living habits is an important measure for prevention.
Urinary tract obstruction and dysuria (20%):
Loss of urine washing, residual urine becomes a good medium for bacterial growth.
Prevention
Cystitis prevention
1. Keep your own cleanliness on weekdays.
2, if you can urinate as much as possible before and after sex life, do not have urine.
3, try to drink cranberry juice, because it has the effect of reducing bacteria adhesion to the urinary tract.
4, you can also drink plenty of water to effectively avoid the possibility of bacterial invasion.
5, during the usual activities because of the urinary habits once every 2-3 hours, in addition to pay attention to the addition of vitamin B group and lactic acid bacteria, etc., prevention is better than treatment, as long as more attention on weekdays, you can reduce the incidence of cystitis opportunity.
Complication
Cystitis complications Complications, hydronephrosis, urinary retention, urinary tract infection
Can be complicated by ureteral progressive stenosis, reflux and the development of hydronephrosis.
Symptom
Symptoms of vesiculitis Common symptoms Urinary frequency urinary pain Urinary urinary bladder volume reduction Low back pain with frequent urination, urine... Urinary foam intermittent urinary proteinuria incompetent infection of bladder fibrosis
When urinating, there is burning pain in the urethra, frequent urination, often accompanied by urgency, severe urinary incontinence, frequent urinary urgency, especially 5 to 6 times per hour, each time the amount of urine is not much, even only a few drops, urinating There may be pain in the lower abdomen at the end. Urine turbidity, sometimes hematuria, often evident in the terminal phase.
Examine
Cystitis examination
1, urography: chronic cystitis showed a reduction in bladder volume, bladder edge rough or irregular.
2, B-ultrasound 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, bladder shrinkage and internal and external margins are not smooth, gangrenous cystitis can also be seen in the bladder gas, inflammatory effusion in the pelvic cavity.
4, MRI performance: bladder wall thickening is often not smooth, signal uneven, mainly low signal.
Diagnosis
Diagnosis and diagnosis of cystitis
diagnosis
Acute cystitis:
The symptoms are more typical, and the general diagnosis is not difficult. According to the history of frequent urination, urgency and dysuria, urine can be seen in routine examination of urine, pus cells, urine bacteria culture per ml of urine bacteria count more than 100,000 to confirm the diagnosis.
Chronic cystitis:
In addition to general examinations, the most important thing is to find out the types of pathogenic bacteria and the results of drug sensitivity tests, and to find out the causes of persistent or recurrent infections. Chronic non-specific cystitis must be differentiated from other types of cystitis, such as tuberculous cystitis, interstitial cystitis, chemical cystitis.
