The effectiveness of the electrocautery technique of vasectomy is compared with the more commonly used ligation technique. Twenty-five hundred cases of vasectomy by electrocautery are presented. The men were Americans who selected vasectomy over a period of 11 years. All cases were performed by one unvarying technique. The vas was cut, and the lumen was cauterized. One end was covered, and all bleeding sites were cauterized. The failure rate in this series was 0.24 percent. A review of the world literature shows that failure rates of the common ligation techniques ranged from 1 to 6 percent. It appears that the electrocautery technique has about one tenth the failures of the standard ligation technique.

To investigate the prevalence of vasectomy training in family practice residencies, a national survey of program directors was undertaken, with a response rate of 93%. Of the respondents, 44% had specific residency programs to provide vasectomy training. Of the residencies with specific training programs, training was a requirement in 18%. A majority of programs with training (54%) had both lecture and surgery components, with the remainder having only surgery. In 45% of the programs with training, residents performed five or fewer vasectomies, and in only 22% of the programs did residents perform more than 10 vasectomies. Among the programs where training was elective, 63% of the residents took the training. Only one program reported a medicolegal problem, which resulted in an out-of-court settlement.
BACKGROUND: This study was conducted to determine whether the open-ended technique of vasectomy is an improvement over traditional closed-ended techniques. METHODS: A switch from closed-ended to open-ended vasectomy was affected in 1988 at the authors' vasectomy clinic. Patients were contacted by telephone 1 to 3 years after vasectomy. RESULTS: The authors successfully contacted 200 of 257 consecutive open-ended vasectomy patients (78 percent). Among the 200 men there were no reported pregnancies among their partners, but there was one (0.5 percent) failure of the sperm to clear, which was treated by repeat vasectomy. There were 3 (1.5 percent) mild infections, 1 (0.5 percent) sperm granuloma, and 1 (0.5 percent) case of late, intermittent pain. CONCLUSIONS: This open-ended vasectomy series has low complication and failure rates, corroborating findings from two larger series. There is no increase in the failure rate using the open-ended technique compared with the closed-ended technique. The single case of late pain is consistent with a decrease in this complication. Open-ended vasectomy approaches the ideal vasectomy.
