Introduction:
Studies have shown that the Li vasectomy can match the effectiveness of and reduce the duration of operation and rate of complications compared to standard vasectomy with bilateral incision.
Materials And Methods:
A prospective, randomised trial was conducted to compare the Li vasectomy with the standard vasectomy with bilateral incision. Data regarding effectiveness, time of operation, the patient's pain and discomfort, and peroperative and postoperative complications were recorded. Overall, 99 patients were entered in the trial, 51 with vasectomy with bilateral incision, 48 with the Li vasectomy.
Results:
No significant difference was found between the two methods with regard to effectiveness, time of operation, the patient's pain and discomfort, and peroperative and postoperative complications. Overall, vasectomy was inadequate in 5%, haematoma was found in 13%, infection in 9%, and scrotal pain or painful ejaculation in 9%.
Discussion:
The Li vasectomy can be learned and practiced under routine conditions by residents in training with the same effectiveness and the same rate of complications as standard vasectomy with bilateral incision. The total morbidity was at the same level as in previous Danish studies, but higher than in the international studies with the Li vasectomy.
