Farooq Qureshi, FRCS Anderson Walk Smithfield. SA 5114 so that the full thickness of the vas is not destroyed. The distal end is fulgurated at the cut surface and the sheath of the vas closed over it with a single suture. This creation of a fascial barrier between the ends prevents spontaneous rejoining, and also facilitates reversal later on if required. Ligatures or metal clips should not be used on the vas, whether absorbable or unabsorbable. These cause necrosis and sloughing of the vessel, and it becomes permanently fibrosed.
