Comparison of Spinal Anesthesia and Spermatic Cord Block for Bilateral Orchiectomy

The goal of this randomized controlled trial is to compare intraoperative pain score, Morphine consumption during 6 and 12 hour after surgery, and postoperative complications between SA and SCB groups in metastatic prostate cancer patient. The main question it aims to answer are: • Is there a difference in the level of pain during bilateral orchiectomy between spinal anesthesia and spermatic cord block? Participants will undergo bilateral orchidectomy. They will be randomly assigned to two groups: the group receiving spinal anesthesia and the group receiving spermatic cord block If there is a comparison group: Researchers will compare intraoperative pain score, Morphine consumption during 6 and 12 hour after surgery, and postoperative complications in both groups of patients.
