Comparison of modified one‐ and two‐layer microsurgical vasovasostomy

Objective To compare the outcome of a modified one‐layer and two‐layer vasovasotomy (VV) in two groups of similar men undergoing vasectomy reversal.Patients and methods The charts and surgical records of all surgical procedures performed on men undergoing a modified one‐ or two‐layer VV between June 1992 and July 1994 were retrospectively reviewed. A successful outcome (patency) was defined as sperm present at follow‐up (mean follow‐up 8 weeks). A modified one‐layer VV was used in 17 men (group 1) and a two‐layer VV in 23 (group 2).Results Sperm were present in both groups if surgery was undertaken after vasal obstruction lasting < 36 months. The modified one‐ and two‐layer VV had equal patency (88% and 90%, respectively) when undertaken after an obstructed interval of 36–96 months; outcomes were poorer if surgery was performed after > 96 months. The mean operative duration was 96 min for a modified one‐layer VV and 167 min for the two‐layer VV.Conclusions The simpler and faster modified one‐layer VV provides sufficient accuracy for successful vasectomy reversal in most cases. For most patients, both procedures have equivalent patency.
