[Intravesical explosion during endoscopic resection. Apropos of a case]

Area of Science:

• Urology
• Surgical Safety

Background:

• Endoscopic bladder surgery carries a risk of rare but severe intravesical explosions.
• These events can result from the formation of explosive gas mixtures within the bladder.

Observation:

• Explosive gas, primarily an air-hydrogen mixture, forms due to tissue carbonization from electrocautery.
• Introduction of air into the bladder during surgical instrument manipulation is a key factor.
• The type of bladder infusion fluid does not significantly influence gas formation.

Findings:

• The primary cause is a combination of tissue charring and air introduction.
• Moderate electrocautery power is crucial.
• Preventing accidental air entry into the bladder is essential.

Implications:

• Implementing preventative measures can significantly reduce the risk of intravesical explosions.
• Surgeons should be aware of gas formation risks during endoscopic bladder procedures.
• Careful technique and equipment management are vital for patient safety.
