Comparison of low-power magnification one-layer vasovasostomy with stent and microscopic two-layer vasovasostomy for...

This study aimed to evaluate a simplified vasovasostomy procedure that shortens the operative time. This was a retrospective (non-randomized) study of men who underwent bilateral vasectomy and consulted for vasovasostomy (02/2014-08/2016). Eight interrupted sutures were used for one-layer full-thickness vasal anastomosis over a 20 or 22 G catheter temporarily inserted in the lumen of the anastomotic site as a stent. Control patients underwent double-layer vasovasostomy. The surgery was significantly shorter in the one-layer group (n = 23) (62 ± 8 vs. 133 ± 15 min, P < 0.001 vs. the two-layer group, (n = 19)). There was no difference in patency between the two groups (95.7 vs. 94.7%, P > 0.999). There was one case of epididymitis in each group. There were no complications like bleeding, scrotal hematoma, hydrocele, or infection. Low-power microscopic one-layer vasovasostomy with stent was simple and had a short operation time. The patency could be similar to that of two-layer vasovasostomy, but prospective studies are necessary for confirmation.
