Percutaneous vasectomy: a simple modification eliminates the steep learning curve of no-scalpel vasectomy.

摘要

PURPOSE: We report a simplified method to avoid the most difficult step of no-scalpel vasectomy, while maintaining its minimally invasive advantages. MATERIALS AND METHODS: Using the no-scalpel vasectomy instruments in percutaneous fashion we perform vasectomy in the office setting without fixation of the vas to skin using the ring clamp. The sharp no-scalpel hemostat punctures the skin. The vas is then grasped with the ringed instrument instead of piercing the vas and performing the supination maneuver, as described for no-scalpel vasectomy. RESULTS: Percutaneous vasectomy was performed in 573 men by a single surgeon. In the 35 consecutive cases recently reviewed average operative time was 9.3 minutes with an additional 67 seconds added when a resident performed the procedure on 1 side in 15 cases. As determined by the knuckle of vas pulled through a puncture, average incisional length was 8.4 mm. Patients reported complete recovery in an average of 8.9 days. No major complications occurred. A single case of recanalization (0.17%) was successfully corrected by repeat percutaneous vasectomy. CONCLUSIONS: Percutaneous vasectomy is a minimally invasive option for permanent male sterilization that avoids the difficult aspects of no-scalpel vasectomy.
