Microsurgical Reconstruction Following Failed Vasectomy Reversal

Abstract

Complete failure of vasectomy reversal usually is due to unrecognized epididymal obstruction. Late failure following initial patency suggests a compromised anastomosis. Repeat vasectomy reversals result in patency and pregnancy rates somewhat lower than previously reported for unselected vasovasostomy and vasoepididymostomy. Because stenosis rates are greater following reoperation, intraoperative and postoperative sperm cryopreservation is recommended.
