[Subcapsular orchiectomy using the ultrasonic surgical aspirator in patients with advanced prostatic cancer]

We report a technique for performing subcapsular orchiectomy using the ultrasonic surgical aspirator (USA). The procedure was simple and safe, and was completed within one hour in 2 patients on whom it was carried out. Operative complications such as bleeding, postoperative pain and wound swelling were minimal, and compression dressings were not necessary. Postoperatively, the serum testosterone value was lowered to the castrate level. We conclude that subcapsular orchiectomy using USA is superior to conventional bilateral scrotal orchiectomy, and will be a useful option.
