Summary
Urinary tract infections caused by Candida are increasing in immunocompromised patients. Advanced imaging like CT and ultrasound aid in diagnosing and managing these challenging Candida bezoar cases.
Area of Science:
- Urology
- Infectious Diseases
- Medical Imaging
Background:
- Recrudescence of immunodepressed patients has led to increased interest in Candida infections, particularly urinary tract infections.
- Improved understanding of clinical and radiological manifestations aids in diagnosis.
Observation:
- Two cases of Candida bezoars in insulin-dependent diabetics are presented.
- Diagnostic methods included intravenous urography (IVU), ultrasonography, and computed tomography (CT) scans.
- Clinical presentations involved renal and pelvic involvement, with imaging revealing filling defects and lesions.
Findings:
- Urinary candidiasis was confirmed through laboratory analysis, urine cultures, and direct examination.
- Imaging findings included delayed renal secretion, pelvic filling defects, and heterogeneous lesions on CT.
- Treatment with amphotericin B resulted in clinical improvement and resolution of signs in both patients.
Implications:
- Noninvasive imaging techniques (ultrasonography, CT) are crucial for diagnosing urinary candidiasis.
- Percutaneous aspiration can also be a valuable diagnostic tool.
- Effective management of urinary candidiasis requires a combination of laboratory and imaging diagnostics.
