Abstract

Modified two layer vasovasostomy and modified one layer vasovasostomy with stent under micro- scope were performed in 63 patients from April 1987 to December 1991 in Fatima General Hospital. Among 56 patients who could be followed up post-operatively, modified two layer vasovasostomy under microscope was performed in 26 patients and modified one layer vasovasostomy with stent under microscope was performed in 31 patients. Patients whose vesovasostomy had been performed using modified two layer technique had a 80.0% patency rate and they had a 60% prenenancy rate. Patients whose vasovasostomy had been performed using modified one layer with stent technique had a 77.4 % patency rate and they had a 54.8 % pregnancy rate. In conclusion, we found a little difference in pregnancy rate and patency rate between two technique but we experienced that modified one layer technique with stenting was easier, more time-saving and cost-effective than two layer technique.
