Radiological Explorations of Patients with Upper or Febrile Urinary Tract Infection.

Area of Science:

• Urology
• Medical Imaging
• Clinical Decision Rules

Background:

• Recent European Association of Urology (EAU) guidelines and Van Nieuwkoop's clinical prediction rule offer criteria for radiological imaging in febrile urinary tract infections (UTIs).
• Assessing adherence to these guidelines is crucial for optimizing patient management and resource allocation in healthcare settings.

Purpose of the Study:

• To evaluate the adherence to Van Nieuwkoop's clinical rule and EAU guidelines for radiological imaging in patients with febrile UTIs.
• To identify factors associated with clinically significant findings on imaging and assess the need for improved clinical prediction rules.

Main Methods:

• Retrospective analysis of medical records for 107 patients with UTIs across four Swiss hospitals.
• Comparison of performed imaging against recommendations from Van Nieuwkoop's rule and EAU guidelines.
• Statistical analysis to determine factors associated with clinically significant imaging findings.

Main Results:

• 58% of UTI patients underwent imaging, with 69% and 64% adequately managed per Van Nieuwkoop's rule and EAU guidelines, respectively.
• Only 47% and 57% of imaging performed were recommended by Van Nieuwkoop's rule and EAU guidelines, respectively.
• Clinically significant findings were linked to urolithiasis, gross hematuria, and urogenital anomalies; 38% of patients with abnormalities met none of the guideline criteria.

Conclusions:

• Adherence to current imaging guidelines for febrile UTIs is suboptimal, particularly when imaging is not explicitly recommended.
• Existing criteria may miss patients with significant abnormalities, highlighting the need for a refined, efficient clinical prediction rule for UTI imaging.
