Background : Vasectomy reversal with microscopic one-layer technique was one of the method tore-anastomosis vasectomized tube.

Objective : To evaluate the effectiveness of vasectomy reversal with microscopic one layer technique.

Setting : King Chulalongkorn Memorial Hospital.

Research design : Descriptive study

Material and Method : Data were collected from OPD cards, IPD cards and operative note. We conducted a retrospective review of 108 patients who underwent vasectomy reversal with microscopic one-layer technique between 2004 and 2014. The effectiveness was interpreted by pregnancy and patency rate. Patient’s age, underlying diseases, alcohol consumption, smoking, history of STD, wife’s age, duration after vasectomy, history of prior vasovasostomy, operative findings, and complications were collected and interpreted for influence of
pregnancy by using statistic t-test, Mann Whitney U test and ROC curve with P < 0.05 considered statistic significant.

Result : Sixty-eight patients were included in this study. The pregnancy rate was 33.8 % (23/68) and the patency rate by semen analysis 3 months after surgery was 75.5 % (40/53). Patients’ age, history of alcohol consumption, smoking, STD, prior vasovasostomy, their wife’s age, operation time and intraoperative findings were not significant. Duration after vasectomy, normal post-semen analysis and the patent of lumen were statistically significantly associated with pregnancy rate. In the group that had time after vasectomy less than 9.5 years had pregnancy rate significantly higher than the other group (46.7%, 23.7%, respectively).

Conclusion : Microscopic one-layer technique of vasectomy reversal provides good outcomes if the time after vasectomy is less than 9.5 years. The patency rate and pregnancy rate are similar to other techniques. Nowadays, this technique seems to be a good option for vasectomy reversal.
