Abstract

Because of the large volume of elective sterilizations performed in this country during the past decade, the high rate of subsequent divorce and remarriage, and improved results of new sterilization reversal techniques, surgeons are receiving rapidly increasing numbers of requests for tuboplasty and vasovasostomy. During the past 10 years (1978-1987), a total of 44 corrective procedures were performed for patients with post-vasectomy azoospermias in this department. Herein, we analyze various factors influencing upon results of anastomosis, and compare results of macroscopic and microscopic anastomotic techniques. The results are as follows: 1. Reversal of vasectomy was requested due to change of mind is 25 patients (56.8%), remarriage in 10 patients (22.7%), death of children in 4 patients (9.1 %), psychologic problem in 4 patients (9.1%) and economic change in 1 patient (2.3%) 2. Results of total vasovasostomies revealed that viable sperms were present in 5 of patients (50%) in macrosurgery and in 22 of 24 patients (92%) in microsurgery. Pregnancy occurred in 2 of 10 patients (20%) in macrosurgery and in 16 of 24 patients (67%) in microsurgery. 3. The longer the interval of obstruction, the less anatomical and functional success rates were noted. 4. It is advised that total open loop technique is far more advanced technically with fool-proof measure. 5. Surgeons who perform the procedure regularly can obtain better results.
