A practical approach to hematuria in children

Area of Science:

• Pediatrics
• Nephrology
• Clinical Medicine

Background:

• Red urine in children can be mistaken for hematuria due to pigments like bilirubin or carotene.
• The
• red diaper syndrome
• is a distinct condition caused by Serratia marcescens.
• Neoplasms are rare causes of hematuria in pediatric populations.

Purpose of the Study:

• To differentiate true hematuria from pigment-induced red urine in children.
• To outline common and rare causes of pediatric hematuria.
• To identify specific neonatal causes of hematuria.

Main Methods:

• Literature review of pediatric hematuria causes.
• Differential diagnosis of red urine.
• Analysis of common etiologies in various pediatric age groups.

Main Results:

• Pigmenturia from bilirubin, carotene, or food dyes can mimic hematuria.
• Serratia marcescens causes the
• red diaper syndrome
• via gastrointestinal colonization.
• Glomerulonephritis, particularly poststreptococcal, is the leading cause of hematuria in children.
• Neonatal hematuria may indicate serious vascular events like renal vein/artery thrombosis or necrosis.

Conclusions:

• Accurate diagnosis of red urine is crucial for appropriate pediatric care.
• Prompt identification of hematuria etiology prevents misdiagnosis and ensures timely treatment.
• Glomerulonephritis remains the primary concern for hematuria in children, while neonatal causes require urgent vascular assessment.
