Pyelonephritis can lead to life-threatening complications

Area of Science:

• Nephrology
• Infectious Diseases
• Urology

Background:

• Acute pyelonephritis presents with fever, flank pain, nausea, vomiting, and costovertebral angle tenderness.
• Symptoms can range from mild illness to severe sepsis.
• Lower urinary tract infection symptoms may also be present.

Purpose of the Study:

• To outline the diagnostic criteria for acute pyelonephritis.
• To emphasize the importance of timely antibiotic initiation.
• To guide management and treatment adjustments based on clinical response and culture results.

Main Methods:

• Diagnosis is based on clinical presentation, including fever (≥ 38.5° C), flank pain, and costovertebral angle tenderness.
• Urine dipstick tests (nitrites, leukocyte esterase) can be negative and do not rule out the diagnosis.
• Clinical assessment guides the initial choice and subsequent modification of antibiotic therapy.

Main Results:

• Early antibiotic administration is crucial.
• Antibiotics effective for lower urinary tract infections may be insufficient for acute pyelonephritis, necessitating prolonged therapy.
• Treatment success is monitored through clinical course and urine culture results.

Conclusions:

• Prompt diagnosis and initiation of appropriate antibiotic therapy are essential for managing acute pyelonephritis.
• Persistent symptoms or lack of improvement within two days warrant reassessment and potential referral to secondary care.
• Treatment plans should be individualized based on pathogen susceptibility and patient response.
