Why are electrolyte-containing irrigation solutions avoided during transurethral resection of the prostate?

Electrolyte-containing irrigation solutions are avoided during transurethral resection of the prostate primarily because they can interfere with the use of cautery. In this surgical procedure, electrosurgery is often utilized to cut and coagulate tissue. The presence of electrolytes in the irrigation fluid can lead to increased electrical conductivity, which might compromise the effectiveness of the cautery and create risks during the operation, such as unpredictable tissue effects or possible electrical injuries.

While there are other considerations related to electrolyte-containing solutions, such as the risk of electrolyte imbalances, the main reason for avoiding them in this specific context relates to their impact on the surgical tools used and the overall safety of the procedure.
