Evaluating hematuria in children. Where to start and how to proceed
1University of Kansas School of Medicine, Wichita 67214.
Insights
Urinary tract bleeding in children often stems from infection or trauma. Diagnosis involves a thorough history, physical exam, and tests like urinalysis, imaging, and sometimes biopsy to understand the cause.
Area of Science:
- Pediatric Nephrology and Urology
- Diagnostic Medicine
Background:
- Hematuria (blood in urine) is a recognized clinical manifestation in pediatric patients.
- Common etiologies include systemic infections and physical trauma, necessitating careful clinical assessment.
Purpose of the Study:
- To outline the diagnostic approach for evaluating urinary tract bleeding in children.
- To emphasize the importance of clinical history and physical examination in guiding investigations.
Main Methods:
- Initial laboratory evaluation typically starts with urinalysis.
- Further diagnostic modalities may include intravenous urography, voiding cystourethrography, endoscopic procedures, sonography, arteriography, and renal biopsy.
- Clinical correlation of findings is crucial for accurate diagnosis.
Main Results:
- A systematic diagnostic pathway is essential for identifying the source of pediatric urinary tract bleeding.
- In some instances, the cause may not be immediately apparent, requiring ongoing monitoring.
Conclusions:
- Comprehensive history and physical examination are foundational for diagnosing urinary tract bleeding in children.
- A stepwise diagnostic approach, starting with urinalysis and progressing to advanced imaging or procedures, is effective.
- Long-term follow-up may be necessary for unexplained cases to ensure renal function preservation.
Abstract:
Bleeding from somewhere along the urinary tract is not unusual in children. Of the many causes, systemic infection and trauma are among the most common. History taking and physical examination should be careful and complete, because the results obtained help direct the laboratory evaluation. Diagnostic testing always begins with urinalysis but may progress to intravenous urography, voiding cystourethrography, endoscopic procedures in the upper and lower urinary tract, sonography, arteriography, or renal biopsy. Some cases remain unexplained and require follow-up to assess renal function.
