Summary
Matrix stones are rare urinary calculi that can mimic tumors. Diagnosis requires a high index of suspicion and may involve ureteroscopy, with percutaneous removal being the primary treatment.
Area of Science:
- Urology
- Nephrology
- Radiology
Background:
- Matrix stones are uncommon urinary calculi.
- They can be misdiagnosed as renal collecting system tumors.
- This presents a diagnostic and therapeutic challenge for urologists.
Observation:
- A case series of 5 patients with urinary matrix stones was identified.
- Patients were referred to a tertiary medical center between 1980 and 2003.
- All cases exhibited complex clinical and radiographic features.
Findings:
- Matrix stones present with variable imaging findings.
- Accurate diagnosis may necessitate invasive procedures like ureteroscopy.
- Percutaneous removal is the main treatment for achieving stone-free status.
Implications:
- A high index of suspicion is crucial for diagnosing matrix calculi.
- Careful selection of radiographic imaging is essential.
- Ureteroscopy may be required for definitive diagnosis.
- Percutaneous removal offers an effective treatment modality.
