Clinical Criteria

1. Symptoms: Patients typically present with symptoms indicative of a urinary tract infection (UTI) and pyelonephritis, which may include:
   - Fever and chills
   - Flank pain or lower back pain
   - Nausea and vomiting
   - Dysuria (painful urination)
   - Increased frequency and urgency of urination

2. History of Exposure: A history of exposure to Salmonella, such as through contaminated food or water, can support the diagnosis. This is particularly relevant in cases where gastrointestinal symptoms precede the urinary symptoms.

Laboratory Criteria

1. Urine Culture: The definitive diagnosis of Salmonella pyelonephritis is made through urine culture, which should yield Salmonella species. This is critical as it differentiates it from other causes of pyelonephritis.

2. Blood Cultures: In severe cases, blood cultures may also be performed to detect the presence of Salmonella in the bloodstream, indicating a more systemic infection.

3. Urinalysis: A urinalysis may show signs of infection, such as:
   - Presence of white blood cells (WBCs)
   - Bacteria
   - Nitrites (if present, indicating gram-negative bacteria)
   - Hematuria (blood in urine)

Imaging Studies

1. Ultrasound or CT Scan: Imaging studies may be utilized to assess for complications of pyelonephritis, such as abscess formation or obstruction of the urinary tract. These studies can help visualize the kidneys and urinary tract to rule out other conditions.

Conclusion

In summary, the diagnosis of Salmonella pyelonephritis (ICD-10 code A02.25) relies on a combination of clinical symptoms, laboratory findings (especially urine and blood cultures), and imaging studies when necessary.
