A renal pelvis abscess is a collection of pus that forms in the renal pelvis, which is the area where urine collects in the kidney before moving to the bladder. This condition can be serious and often requires medical attention.
Pathophysiology
Structure
- Kidneys: Two bean-shaped organs that filter blood to produce urine.
- Renal Pelvis: The funnel-like structure in each kidney where urine collects.
Blood Supply
- Renal Arteries: Supply blood to the kidneys from the abdominal aorta.
- Renal Veins: Drain blood from the kidneys back to the heart.
Nerve Supply
- The kidneys receive nerve supply from the autonomic nervous system, which controls involuntary functions.
Types of Renal Pelvis Abscess
- Simple Renal Abscess: A localized collection of pus in the renal pelvis.
- Complex Renal Abscess: Involves surrounding tissue and may have multiple loculations.
Causes of Renal Pelvis Abscess
Here are 20 possible causes:
- Bacterial Infection: Most common cause, often from urinary tract infections (UTIs).
- Kidney Stones: Can block urine flow and lead to infection.
- Diabetes: Increases risk of infections.
- Obstruction: Tumors or abnormalities can block urine flow.
- Catheter Use: Long-term use of catheters can introduce bacteria.
- Immune Deficiency: Weakens the body’s ability to fight infections.
- Previous Surgery: Can lead to infection in the kidney area.
- Pyelonephritis: Kidney infection can lead to abscess formation.
- Anatomical Abnormalities: Structural issues in the urinary tract.
- Chronic Inflammation: Long-standing irritation can lead to abscesses.
- Hematogenous Spread: Infection spreads from other parts of the body through the blood.
- Fungal Infection: Rare but possible in immunocompromised patients.
- Viral Infections: Certain viruses can contribute to abscess formation.
- Trauma: Injury to the kidney area can lead to infection.
- Chronic Kidney Disease: Impairs kidney function and increases infection risk.
- Prostatitis: Inflammation of the prostate can contribute to urinary infections.
- Cirrhosis: Liver disease can affect immune response.
- Urinary Retention: Inability to empty the bladder fully can lead to infection.
- Foreign Bodies: Objects in the urinary tract can cause irritation and infection.
- Chemotherapy: Lowers immunity and increases infection risk.
Symptoms of Renal Pelvis Abscess
Patients may experience a variety of symptoms, including:
- Fever: Often high and persistent.

Diagnostic Tests for Renal Pelvis Abscess
Doctors may use the following tests to diagnose a renal pelvis abscess:
- Urinalysis: Checking urine for signs of infection.
- Blood Tests: To detect infection and kidney function.
- Imaging Tests:
- Ultrasound: Uses sound waves to visualize the kidneys.
- CT Scan: Provides detailed images of the kidneys.
- MRI: Useful in certain cases for detailed images.
- X-rays: Sometimes used to view kidney stones or abnormalities.
- Culture Tests: Identifying bacteria from urine or blood.
- Biopsy: Taking a sample if an abnormality is found.
- Nuclear Scans: To assess kidney function and blood flow.
- IV Pyelogram: X-ray after injecting dye to see urine flow.
- Cystoscopy: Viewing the bladder and urethra directly.
- Laparoscopy: Minimally invasive surgery to examine the kidneys.
- Serum Creatinine: Testing kidney function.
- Electrolyte Panel: Checking for imbalances.
- C-Reactive Protein: Indicates inflammation in the body.
- Liver Function Tests: To assess overall health.
- Amylase and Lipase: To rule out pancreatic issues.
- Thyroid Tests: To rule out metabolic issues.
- Echocardiogram: In some cases, to assess heart function.
- Chest X-ray: To check for other potential infections.
- Urine Cytology: To check for abnormal cells.
- Antibody Tests: To assess immune response.
Non-Pharmacological Treatments
Non-drug treatments for renal pelvis abscess may include:
- Hydration: Drinking plenty of fluids.
- Rest: Allowing the body to recover.
- Dietary Changes: Eating a balanced diet to support recovery.
- Heat Therapy: Applying heat to relieve pain.
