A comparison of open-end versus closed-end vasectomies: a report on 6220 cases.

This study was done to determine if there was a difference in results when both vas ends were closed or when the prostatic end was closed and the testicular end left open. The author performed 6220 vasectomies between June 1, 1972 and June 1, 1992. The first series consisted of 3081 vasectomies in which both ends of the vas deferens were closed. The second series consisted of 3139 vasectomies in which the testicular end of the vas deferens was left open while the prostatic end only was closed. No portion of the vas was excised. Congestive epididymitis was diagnosed in 6% of cases utilizing closed-end vasectomy and 2% of cases where the open-end vasectomy was performed. Open-end vasectomy is recommended because the incidence of congestive epididymitis is reduced.
