Objectives
To describe and evaluate the outcomes of a new epididymovasostomy technique.
Patients and Methods
Nine patients with obstructive azoospermia were treated at the Minia University Hospital using a new microsurgical bilateral epididymovasostomy technique. The technique involved the opening of a small window in the tunica of the epididymis, making an opening in the underneath epididymal tubule and keeping it open by fixing the edges of the epididymal opening to the edge of the epididymal tunica with four 10/0 nylon sutures. The abdominal cut end of the vas deferens was then anastomosed to the epididymal opening by suturing the epididymal tubule, fixed to its tunica in one layer, to the full thickness vas deferens. The main outcome measure was finding sperm in the ejaculate.
Results
Sperm was found in the ejaculate in six out of nine patients after our new, one-layer, epididymovasostomy technique. Mean +/- SD operating time was 176 +/- 23 min.
Conclusions
This new, one-layer, epididymovasostomy technique provides a simple alternative method of epididymovasostomy, with reasonable outcomes. More cases and follow-up are needed to make meaningful comparisons with conventional epididymovasostomy.
