    Hydrogen gas is commonly produced during transurethral electrosurgery from intracellular water electrolysis. The gaseous mixture only becomes explosive when mixed with external oxygen.

    Area of Science:

    • Urology
    • Biochemistry
    • Surgical Safety

    Background:

    • Transurethral electrosurgery generates gases in all tissues.
    • Hydrogen is a primary gas produced during this procedure.
    • The source of this hydrogen gas is not fully understood.

    Purpose of the Study:

    • To investigate the origin of hydrogen gas liberated during transurethral electrosurgery.
    • To understand the conditions under which surgical gases pose an explosion risk.

    Main Methods:

    • Analysis of gases produced during transurethral electrosurgery.
    • Postulation of hydrogen gas derivation from intracellular water electrolysis.

    Main Results:

    • High concentrations of hydrogen gas are consistently produced.

  • Electrolysis of intracellular water is postulated as the main source.
  • The surgical gas mixture becomes explosive only with the addition of external oxygen.

    • Conclusions:

    • Intracellular water electrolysis is the likely source of hydrogen gas during transurethral electrosurgery.
    • Awareness of oxygen presence is critical for preventing surgical fires and explosions.
