Xanthogranulomatous pyelonephritis (XGP) is rare in infants. This case highlights successful partial nephrectomy in a 2-month-old, preserving renal function and mass.

Area of Science:

  • Pediatric Nephrology
  • Pediatric Urology
  • Pediatric Pathology

Background:

  • Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic granulomatous inflammation of the kidney, often associated with infection and obstruction.
  • It is exceptionally uncommon in infants, posing diagnostic challenges due to its varied presentation.
  • Differential diagnoses in children with renal masses include Wilms tumor, multicystic dysplastic kidney, and renal abscess.

Observation:

  • A 2-month-old female infant presented with a urinary tract infection and a renal mass identified via ultrasound.
  • Preoperative imaging and clinical presentation suggested common pediatric renal pathologies.
  • Histopathological examination confirmed the diagnosis of xanthogranulomatous pyelonephritis.

Findings:

Related Experiment Videos

  • The case demonstrates that xanthogranulomatous pyelonephritis can occur in neonates, necessitating its inclusion in the differential diagnosis of pediatric renal masses.
  • Unlike traditional treatment involving nephrectomy for diffuse XGP, this study reports successful renal mass preservation using partial nephrectomy.
  • The affected kidney exhibited normal growth and retained residual function post-surgery.

    • Implications:

    • Parenchyma-saving surgery, such as partial nephrectomy, is a viable and recommended approach for pediatric xanthogranulomatous pyelonephritis.
    • Preserving renal mass and function in young children with XGP is crucial for long-term renal health.
    • This approach challenges the historical necessity of nephrectomy for diffuse XGP in pediatric patients.
