Purpose: Microscope assisted vasovasostomy(MAVV) has been adapted as the standard procedure for vasectomy reversal, either in one layer or two layer fashion of anastomosis. The patency rate was variable from 46-96%, and only few research recruited Asian people. Here we reviewed 9 years data from single institution, investigating the actual patency rate and possible factors related to postoperative obstruction.
Materials & Methods: From March 2010 to Aug 2018, 51 Taiwanese receiving microscope assisted vasovasostomy due to infertility were recruited. Patients who had no semen analysis data post surgery were excluded, and total 33 cases were selected for analysis after all. Lumen patency was evaluated by saline instillation during surgery. The definition of patency is the presence of sperm from semen analysis. SPSS version 19 was used for statistic analysis.
Results: The mean age of these patients was 41 years old with only one patient over 50 years old(Table 1). The mean operation time was 120 minutes, and blood loss was around 3ml. 9 zero nylon was mostly used in these cases for single layer anastomosis. The patency rate was 81.8% in our study, with mean age 42 years old. There were no statistical differences between the patent and obstructive group in age, operative time or blood loss.
Conclusion: Microscope assisted vasovasostomy is a good method for vasectomy reversal, with patency rate up to 81.8%. Further study is warranted to evaluate the possible factors contributing to the postoperative patency.
