Renal hemangioma, a rare kidney tumor, can cause significant hematuria. Ureterorenoscopy is key for diagnosis, with surgery an option if less invasive treatments fail.

Area of Science:

  • Urology
  • Nephrology
  • Oncology

Background:

  • Renal hemangioma is a rare benign renal tumor.
  • Hematuria is an uncommon presenting symptom of renal hemangioma.
  • Diagnostic challenges exist for identifying renal hemangioma via standard imaging.

Observation:

  • A 40-year-old female presented with persistent gross hematuria, anemia, and right flank pain.
  • Extensive imaging was inconclusive; however, ureterorenoscopy identified a bleeding source in the upper pole of the right kidney.
  • Endoscopic treatment was not feasible, necessitating a right upper pole nephrectomy.

Findings:

  • Histopathological analysis confirmed the diagnosis of renal hemangioma.
  • Standard imaging modalities lack sensitivity for detecting renal hemangioma.

  • Ureterorenoscopy proved to be the diagnostic method of choice.

    • Implications:

    • Ureterorenoscopy is crucial for diagnosing renal hemangioma and may allow for endoscopic treatment.
    • Surgical intervention, including nephrectomy, remains a viable option for refractory cases.
    • Early diagnosis and appropriate management are essential for favorable patient outcomes.
