Solitary fibrous tumor of kidney

Last edited: 4/15/2026

Overview

Solitary fibrous tumor of the kidney is a rare neoplasm characterized by its mesenchymal origin and potential for local invasion or metastasis, though it often presents as a benign lesion 1.

Diagnosis

  • Imaging: Utilize multiphase postcontrast imaging for detailed characterization and surgical planning, particularly in complex cases like Wilms tumors 1.
  • Ultrasound: Confirm diagnosis and assess compensatory enlargement in pediatric solitary kidneys 2.
  • Urinalysis: Routinely performed at diagnosis for infants and children with compensatory enlargement 2.
  • Further Imaging: Avoid routine use beyond ultrasound if no additional urinary tract anomalies are detected 2.
  • Management

  • Surgical Intervention: Primary treatment typically involves surgical resection, tailored based on imaging findings 1.
  • Follow-Up: Lifelong monitoring recommended for pediatric patients with solitary kidneys to assess growth and function 2.
  • Nutritional Guidance: Avoid excessive protein and salt intake to support kidney health 2.
  • Sports Participation: Consider individual risk assessment; allow participation in sports with informed consent regarding potential risks 3.
  • Special Populations

  • Pediatrics: Focus on compensatory kidney growth and avoid unnecessary imaging beyond initial ultrasound 2.
  • Sports Participation: Decision varies; majority allow participation with risk discussion, though personal bias may influence decisions 3.
  • Key Recommendations

  • Confirm diagnosis of solitary kidney in pediatric patients using neonatal ultrasound and avoid routine additional imaging unless other anomalies are present (Evidence: Moderate 2).
  • Perform urinalysis at diagnosis for infants and children with compensatory enlargement of the solitary kidney (Evidence: Moderate 2).
  • Allow sports participation for individuals with a solitary kidney after discussing potential risks, acknowledging variability in physician attitudes (Evidence: Weak 3).
