Renal varices

R A Peterson, L R Peterson

    Journal of the Canadian Association of Radiologists
    |March 1, 1980

    Summary
    This summary is machine-generated.

    Renal vein varices, abnormalities causing intermittent hematuria, can be diagnosed using renal venography. This procedure involves injecting epinephrine into the renal artery to confirm the condition, even in patients without prior bleeding history.

    Area of Science:

    • Urology
    • Radiology
    • Vascular Abnormalities

    Background:

    • Renal vein varices are vascular abnormalities that can lead to intermittent hematuria.
    • These varices may be present in individuals without a history of bleeding episodes.

    Observation:

    • Characteristic changes on drip infusion pyelogram and retrograde pyelogram suggest the presence of renal vein varices.
    • These imaging techniques provide initial diagnostic clues.

    Findings:

    • Renal venography, performed seconds after ipsilateral renal artery epinephrine injection, is the definitive diagnostic method.
    • This interventional radiological technique confirms the diagnosis of renal vein varices.

    Implications:

    • Accurate diagnosis of renal vein varices is crucial for managing patients with unexplained hematuria.
  • Understanding the diagnostic pathway aids in clinical decision-making and treatment planning.
  • Epinephrine-enhanced renal venography offers a reliable method for identifying these vascular anomalies.
