Obturator foramen approach. I. A new technique for reconstruction of the vas deferens after extensive resections.

A new approach for restoring continuity of the vas deferens after long segment resection is presented. The technique was used in six patients. It consists of passing the pelvic segment of the vas through the obturator foramen for anastomosis with the scrotal vasal segment. No complications were encountered, and the results were excellent. The vasal length was studied in 37 cadavers of different ages. The portion of the vas that could be spared by the obturator approach was calculated and found to represent as much as one third of the total vasal length. The indications for the technique are outlined.
