Cystitis is the medical term for inflammation of the bladder. It’s commonly caused by a bacterial infection, but it can also result from other factors like irritation from chemicals or medications.
Pathophysiology
Structure:
- Bladder Anatomy: The bladder is a hollow organ that stores urine from the kidneys before it’s expelled from the body.
- Mucosal Layer: Lines the inside of the bladder, providing a barrier against pathogens and irritants.
Blood Supply:
- Arteries: Superior and inferior vesical arteries supply blood to the bladder.
- Veins: Drain blood through the vesical veins into the internal iliac veins.
Nerve Supply:
- Autonomic Nervous System: Controls bladder contractions and relaxation.
- Somatic Nerves: Manage the external urethral sphincter.
Types of Cystitis
- Acute Bacterial Cystitis: Sudden onset, usually caused by E. coli.
- Chronic Cystitis: Long-term inflammation, may be due to persistent infections or other underlying conditions.
- Interstitial Cystitis (Painful Bladder Syndrome): Chronic condition causing bladder pressure and pain.
- Radiation Cystitis: Resulting from radiation therapy to the pelvic area.
- Hemorrhagic Cystitis: Characterized by bleeding from the bladder lining.
Causes of Cystitis
- Bacterial Infections: Most commonly E. coli from the digestive tract.
- Sexual Activity: Can introduce bacteria into the urinary tract.
- Urinary Catheters: Provide a pathway for bacteria.
- Menopause: Reduced estrogen levels can change the urinary tract environment.
- Vaginal Birth: Can introduce bacteria to the bladder.
- Weakened Immune System: Increases susceptibility to infections.
- Use of Spermicides: Can irritate the urethra.
- Blocked Urinary Tract: Stones or tumors can cause obstruction.
- Certain Medications: Diuretics or other drugs can irritate the bladder.
- Chemotherapy: Can cause hemorrhagic cystitis.
- Radiation Therapy: Especially in the pelvic area.
- Diabetes: High sugar levels can promote bacterial growth.
- Dehydration: Concentrated urine can irritate the bladder.
- Poor Hygiene: Increases risk of bacterial entry.
- Urinary Tract Abnormalities: Structural issues can trap bacteria.
- Foreign Objects: Such as spermicides or diaphragms.
- Reflux of Urine: From the kidneys to the bladder.
- Certain Foods and Drinks: Like caffeine, alcohol, and spicy foods can irritate.
- Stress: May affect immune function.
- Prolonged Sitting: Especially in hot tubs or pools, increasing bacterial exposure.
