During a transurethral resection of the prostate, bleeding is controlled by?

In a transurethral resection of the prostate (TURP), controlling bleeding is crucial due to the vascular nature of the prostate tissue and the potential for significant blood loss during the procedure. Cauterization is commonly used in this context as it involves the application of heat to tissues to seal blood vessels, thus preventing further bleeding. This method effectively coagulates the blood vessels, minimizing intraoperative hemorrhage and maintaining a clearer surgical field, which is essential for the surgeon's visibility and the overall success of the procedure.

While other methods such as irrigation can help manage fluid levels and maintain visibility, it does not directly control bleeding. Suture ligature is generally not utilized in TURP because the procedure involves removing tissue through a resectoscope, where direct suturing is impractical. Gelfoam can assist in hemostasis but is not the primary method for controlling bleeding during the active resection process.

Cauterization's effectiveness, safety, and efficiency make it the preferred choice for managing bleeding in TURP, thus ensuring a better outcome for the patient.
