Efficacy of Intraoperative Mitomycin-C in Vasovasostomy Procedure: A Randomized Clinical Trial
Journal Title: International Journal of Fertility & Sterility - Year 2019, Vol 13, Issue 3
Abstract
Background Two-six percentage of vasectomized men will ultimately seek vasectomy reversal, which late stricture and obstruction after operation are relatively common. To find a method for improving vasovasostomy outcomes, we used intra-operative local mitomycin-C (MMC) preventing possible fibrosis and stricture. Materials and Methods In this randomized clinical trial, 44 patients were assigned to two groups randomly during a one-year study and the data of 40 patients were analyzed. The patients were followed up for 6 months after surgery. The case group (n=19) was treated by vasovasostomy with intra-operative local MMC. The control group (n=21) underwent standard vasovasostomy. Results Mean sperm count in MMC group was significantly higher than the controls. The sperm count of more than 20 million/ml was respectively 53% and 14% in MMC and control groups. In a subgroup where the interval between vasectomy and reversal was 5-10 years, post-reversal azoospermia was absent in MMC group, but 50% of the controls were still azoospermic. In addition, 80% of MMC group had more than 20 million/ml sperms, but all of the controls had less than 20 million/ml sperms. No significant complication was seen. Conclusion Intra-operative local MMC in vasovasostomy can be regarded as a safe and efficient technique which has several advantages including lower cost. Increase of sperm count is the main effect of local MMC applica- tion that is more prominent when the interval between vasectomy and reversal is 5-10 years (Registration number: IRCT2015092324166N1).
