Summary
A new diagnostic algorithm for microscopic hematuria, using intravenous urography (IVU) after initial negative tests, identified abnormalities in some patients with persistent bleeding. This approach helps diagnose causes of persistent microhematuria.
Area of Science:
- Urology
- Diagnostic Imaging
Background:
- Microscopic hematuria requires a thorough diagnostic workup to identify underlying causes.
- Initial evaluations often include renal ultrasound (US) and cystoscopy.
Purpose of the Study:
- To assess a diagnostic algorithm for microscopic hematuria.
- To determine the utility of intravenous urography (IVU) as a secondary study for persistent microhematuria.
Main Methods:
- 372 patients with microhematuria and negative initial tests underwent renal US and cystoscopy.
- Patients with persistent microhematuria after 3 months were evaluated with IVU.
Main Results:
- Of 81 patients with persistent microhematuria, 75 underwent IVU.
- IVU revealed abnormalities in 11 patients, including stones and tumors.
- No abnormalities were found in IVU performed on patients whose hematuria resolved.
Conclusions:
- Cystoscopy and renal US are effective initial evaluations for microhematuria.
- IVU can be beneficial for diagnosing persistent microhematuria when initial workup is inconclusive.
