[Vasectomy by the Li method].
The vasectomies were performed by the residents of the department without prior training in this surgical procedure. Four and a half months after the operation, a questionnaire was sent to the patients, posing questions about discomfort, pain, swelling, discolouration and infection as well as pain and bleeding following ejaculation. Eighty-five percent of the patients returned the questionnaire. We found a low rate of primary surgical complications: seven cases of infection (including antibiotic treatment on the suspicion of infection; one was verified as epididymitis) and one granuloma. Sixty-four, 39 and 45% respectively complained about postoperative pain, swelling and discolouration, but only half of the patients in each of these groups indicated discomfort. We see this as an indication that the method has a low rate of complications and, that this may be further reduced if the surgeon achieves sufficient routine in the procedures.
