The Differential Diagnosis of Sterile Pyuria in Pediatric Patients: A Review

Area of Science:

• Pediatric Nephrology
• Pediatric Infectious Diseases
• Clinical Medicine

Background:

• Sterile pyuria is a frequent clinical finding in pediatric populations.
• Existing literature lacks comprehensive details on diagnoses and clinical features of sterile pyuria in children.
• The definition of pyuria itself is not consistently applied in current medical literature.

Purpose of the Study:

• To establish an evidence-based framework for the differential diagnosis of sterile pyuria in pediatric patients.
• To systematically review and categorize the diverse causes of sterile pyuria in children.
• To provide clinicians with a structured approach to evaluating pediatric sterile pyuria.

Main Methods:

• Extensive literature search across multiple databases.
• Classification of identified causes into Infectious and Non-Infectious categories.
• Sub-categorization of infectious causes (viral, bacterial, other infections, STIs, post-antibiotic therapy) and non-infectious causes (systemic disease, renal disease, drug-related, adjacent inflammation).

Main Results:

• Identified numerous causes of pediatric sterile pyuria, categorized as Infectious or Non-Infectious.
• Infectious causes encompass viral, bacterial, tuberculosis, fungal, parasitic, sexually transmitted infections, and recent antibiotic therapy.
• Non-Infectious causes include systemic diseases, renal conditions, drug-related issues, and inflammation near the genitourinary tract.

Conclusions:

• A comprehensive differential diagnosis for pediatric sterile pyuria is essential for effective clinical management.
• Clinicians should consider a wide range of potential etiologies when encountering persistent symptoms of sterile pyuria in children.
• This review provides a structured approach to aid in the diagnosis and management of pediatric sterile pyuria.
