Purpose:
We compared the effectiveness and complications associated with 2 common vasectomy occlusion techniques, namely clipping and excision of a small vas segment and thermal cautery with fascial interposition and an open testicular end.
Materials And Methods:
We retrospectively reviewed the computerized records of 3,761 men who underwent initial vasectomy at a single university hospital family planning clinic and at 2 private clinics in the Quebec City, Canada area, including concurrent and historical controls. All procedures were performed by 1 surgeon, who used the scalpel-free technique to expose the vas.
Results:
The risk of vas occlusion failure in men with at least 1 semen analysis was much greater in the clipping and excision group than in the cautery, interposition and open testicular end group (126 of 1,453 or 8.7% versus 3 of 1,165 or 0.3%, OR 37, 95% CI 12 to 116). Medical consultations for hematoma or infection were more frequent in the cautery group (28 of 1,721 cases or 1.6% versus 10 of 2,040 or 0.5%, OR 3.4, 95% CI 1.6 to 6.9). Consultations for noninfectious pain were similar for the 2 techniques (71 of 1,721 cases or 4.1% versus 72 of 2,040 or 3.5%, OR 1.2, 95% CI 0.8 to 1.6).
Conclusions:
Cautery and interposition with an open testicular end are much more effective than clipping and excision. The effectiveness and morbidity associated with the components of the cautery, interposition and open testicular end technique need further evaluation.
Insights
Thermal cautery with fascial interposition and an open testicular end is a more effective vasectomy technique than clipping and excision. This method significantly reduces vas occlusion failure rates, though complications require further study.
Area of Science:
- Urology
- Family Planning
- Surgical Techniques
Background:
- Vasectomy is a common male sterilization procedure.
- Two prevalent occlusion techniques include clipping/excision and thermal cautery with fascial interposition and open testicular end.
Purpose of the Study:
- To compare the effectiveness and complication rates of two common vasectomy occlusion techniques: clipping and excision versus thermal cautery with fascial interposition and open testicular end.
Main Methods:
- Retrospective review of 3,761 vasectomy records from a university hospital and two private clinics.
- All procedures performed by a single surgeon using the scalpel-free technique.
Main Results:
- Vas occlusion failure was significantly higher with clipping and excision (8.7%) compared to cautery, interposition, and open testicular end (0.3%).
- The cautery group had more medical consultations for hematoma or infection (1.6% vs. 0.5%).
- Noninfectious pain consultations were similar between the two techniques.
Conclusions:
- Thermal cautery with fascial interposition and an open testicular end demonstrates superior effectiveness in vasectomy occlusion compared to clipping and excision.
- Further evaluation is needed to assess the effectiveness and morbidity of individual components of the cautery technique.
