Scalpel versus no-scalpel incision for vasectomy

Vasectomy surgical techniques: a systematic review
|
| Current evidence supports no-scalpel vasectomy as the safest surgical approach to
isolate the vas when performing vasectomy. Adding FI increases effectiveness beyond ligation and
excision alone. Occlusive effectiveness appears to be further improved by |

|
A comparison of vas occlusion techniques: cautery more effective
|
| The use of cautery as part of the vasectomy procedure significantly reduced vasectomy failure rates compared with ligation and excision plus fascial interposition as part of the procedure. It is unclear from our results and those of others whether fascial |

Vasectomy by ligation and excision, with or without fascial
|
| Fascial interposition significantly improves vasectomy success when ligation and
excision is the method of vas occlusion.

|
Effectiveness and complications associated with 2 vasectomy occlusion techniques
|
| The risk of vas occlusion failure was much greater in the clipping and excision group than in the cautery, interposition and open testicular end group 8.7% versus 0.3%. Medical consultations for hematoma or infection were more frequent in the cautery gro |

|
Recent developments in vasectomy
|
| Recent evidence suggests that cautery plus fascial
interposition is more effective than ligation and
excision plus fascial interposition, but fascial
interposition is technically challenging; research
is needed to determine where cautery alone fits

Vasectomy in the United States, 2002
|
| Overall 37.8% of physicians reported currently using no scalpel vasectomy and almost half of the vasectomies performed in 2002 were no scalpel vasectomies. Methods of vas occlusion varied in and among specialties with a combination of ligation and caute |

The First Semen Analysis After Vasectomy: Timing and Definition of Success.
|
| A prerequisite of preoperative counselling for vasectomy should be an understanding by the patient that vasectomy is not a procedure but a process requiring a SAV to determine success. On the basis of published evidence, we recommend a single SAV at 12 w |

Vasectomy Follow up: Clinical Significance of Rare nonmotile Sperm in Postoperative Semen Analysis.

| Our data show that despite aggressive counseling, compliance with follow-up testing is very
poor. Patient-reported complaints are common but minor. We found that most men with RNMS become
azoospermic and propose that the presence of RNMS is consistent w |

Azoospermia should not be given as the result of vasectomy

Persistence or reappearance of nonmotile sperm after vasectomy: Does it have clinical consequences?
|
| Nonmotile sperm was found in 33% of the patients 12 weeks after vasectomy. The mean time to azoospermia was 6.36 months. Azoospermia as a criterion for sterility leads to unnecessary prolonged semen analysis in a large percentage of the vasectomized pati |

A prospective study of time and number of ejaculations to azoospermia after vasectomy by ligation and excision.
|
| Only 60/100 and 27.9/100 men were azoospermic by 12 weeks and 20 ejaculations, respectively. 16.6% did not achieve azoospermia by 24 weeks, of whom 25 (11.5% of all participants) were considered to have vasectomy failure. |

Post vasectomy analysis: call for a uniform evidence-based protocol

Complications of Vasectomy

Frequency and patterns of early recanalization after vasectomy
