My vasectomy was performed about 17 years ago and at that time, they still made a 1/2-to-3/4 inch incision on either side of the scrotum, using two or three sutures to close each incision. I drove home afterwards, in a car with a manual transmission and never had any swelling or pain and no complications whatsoever. Instead of only suturing and ligating the vas deferens on each side, they also suture and ligate the artery and vein in the exact same manner. The single median raphe incision should only be 3/4 to 1 1/4 inch, not much worse than my vasectomy. I think the worst trauma inflicted will be from pulling the cords down as far as possible, typically resulting in swelling and inflammation at the remaining stump of each cord. Here's a good description (http://www.urologymatch.com/Orchiectomy.htm) of the procedure, scroll down to the bottom of the page. Page 429 of Glenn's Urologic Surgery (http://books.google.com/books?id=GahMza ... es&f=false) describes the procedure in even more medical terms, with excellent illustrations.
Hell, if I was a trained surgeon, I'd probably do this myself. (Please don't flame me for this one, folks. I said if, and I'm not, so I won't.)
Dr. Christine McGinn performs simple orchiectomy in a hospital with a general anesthetic, driving the cost up to almost $5K. Using a less risky spinal block is performed strictly for the comfort of the patient, and not for any other legitimate medical reason. Hospital expense and general anesthesia are completely unnecessary expenses for simple orchiectomies. Radical and/or inguinal orchiectomy is a totally different matter, especially when dissection of the lymph nodes is required for pathology.
