    Summary

    Distilled water irrigation during transurethral electroresection (TUR) can cause dangerous hemolysis. Sorbitol and Mannitol irrigation fluids effectively prevent these life-threatening complications.

    Area of Science:

    • Urology
    • Biochemistry

    Context:

    • Transurethral electroresection (TUR) is a common urologic procedure.
    • The choice of irrigating fluid is critical for patient safety during TUR.

    Purpose:

    • To evaluate the potential for distilled water to cause hemolysis during TUR.
    • To compare the safety of distilled water with Sorbitol and Mannitol as irrigating fluids.

    Summary:

    • Distilled water irrigation in animal models demonstrated significant hemolysis, particularly when mixed with blood.
    • Intravenous instillation of distilled water also induced hemolysis, though less severe.
    • Sorbitol and Mannitol solutions showed no measurable hemolytic effect.

    Impact:

    • Massive absorption of hemolyzed erythrocytes during TUR can lead to dangerous complications, especially for novice surgeons.
    • The duration, technique, and pressure dynamics of the resection influence the risk of hemolysis.
    • Using Sorbitol and Mannitol irrigation fluids during TUR reliably prevents hemolytic incidents, enhancing patient safety.
