Abstract

PURPOSE
Because of the volume of elective sterilizations performed in the world during the past decade, the vasectomy was a popular method for male sterilization in Korea and this, in turn, had been followed by an increase in the number of patient requiring vasectomy reversal with the high rate of subsequent divorce and remarriage. Recently, many authors have reported high success rates of vasovasostomy using microsurgical techniques and we performed modified two layer vasovasostomy with intravasal silicone tube to increase postoperative patency and pregnacy rate. METHODS: Microscopic vasovasostomy was performed in 9 patients at our department using modified two layer vasovasostomy with silicone tube insertion. Their ages ranged from 28 to 44 with an average of 35.78+/-1.36 years. Standard Guibor silicone tube, consisting of two 17.7cm, 0.064cm diameter, malleable, stainless steel probes connected by 29cm of silicone tubing wedged onto disposable probes, were used in all cases.
RESULTS
Success rates were 88.8% for patency and pregnancy 44.4% for pregnancy in modified two layer vasovasostomy with silicone tube insertion. The patency rates were higher in cases of long postoperative day and in cases of short duration of vasectomy and vasovasostomy.
CONCLUSION
We used a modified method to correspond the patency and pregnancy rate in microscopical modified two layer vasovasostomy using the intravasal silicone tube permanently. This method brings normal patency in microsurgical vasovasostomy because the silicone tube prevent obstruction of anastomosed site of the vas permanently.
