Haematuria.

J Aagaard, U Hansen

    Scandinavian Journal of Urology and Nephrology
    |January 1, 1985

    Summary
    This summary is machine-generated.

    Rare vascular lesions like hemangiomas and varicose veins can cause significant hematuria, posing diagnostic challenges. Pyeloscope diagnosis during surgery helped identify these lesions, avoiding unnecessary nephrectomy in two patients.

    Area of Science:

    • Urology
    • Vascular Lesions
    • Diagnostic Imaging

    Background:

    • Hematuria is a common urological symptom, but its causes are diverse.
    • Rare vascular lesions, such as hemangiomas and varicose veins, are infrequently associated with gross hematuria.
    • Diagnostic challenges arise when standard clinical investigations fail to identify the source of bleeding.

    Observation:

    • Two patients presented with severe gross hematuria.
    • Initial clinical investigations, including imaging and cystoscopy, were inconclusive in identifying the bleeding source.
    • The patients had undergone extensive diagnostic workups without a definitive diagnosis.

    Findings:

    • Peroperative diagnosis using a pyeloscope identified rare vascular lesions as the cause of hematuria.

    Related Experiment Videos

  • The pyeloscope allowed for direct visualization of the lesions within the urinary tract.
  • Histopathological examination confirmed the nature of the vascular lesions.

    • Implications:

    • This case highlights the importance of considering rare vascular lesions in the differential diagnosis of unexplained gross hematuria.
    • Pyeloscopy can be a valuable tool for intraoperative diagnosis of obscure urinary tract pathologies.
    • Timely and accurate diagnosis can prevent unnecessary and potentially morbid procedures, such as nephrectomy.
