Scalpel versus no-scalpel incision for vasectomy

Area of Science:

• Urology
• Surgical Techniques
• Men's Health

Background:

• Vasectomy is a common surgical procedure for male sterilization.
• Two primary surgical approaches exist: the incisional method and the no-scalpel technique.
• The no-scalpel technique aims to minimize adverse events and reduce procedure time.

Purpose of the Study:

• To compare the effectiveness, safety, and acceptability of the incisional versus no-scalpel vasectomy approaches.
• Evaluate outcomes such as bleeding, pain, hematoma, infection, operating time, and contraceptive efficacy.

Main Methods:

• Comprehensive literature search of multiple databases (CENTRAL, MEDLINE, POPLINE, LILACS, EMBASE) and clinical trial registries.
• Inclusion of randomized controlled trials and controlled clinical trials, with no language restrictions.
• Data extraction on safety, acceptability, operating time, contraceptive efficacy, and discontinuation, with statistical analysis using Peto odds ratios and 95% confidence intervals.

Main Results:

• The no-scalpel technique demonstrated significantly less perioperative bleeding, scrotal pain, and incisional infection compared to the standard incisional method.
• Both techniques showed reduced hematoma formation with the no-scalpel approach.
• Operations using the no-scalpel method were faster, allowing for quicker resumption of sexual activity, though one smaller study did not confirm these differences.

Conclusions:

• The no-scalpel vasectomy approach is associated with reduced bleeding, hematoma, infection, and pain, alongside shorter operation times compared to the traditional incision technique.
• Vasectomy effectiveness was found to be comparable between the no-scalpel and incisional methods.
• The no-scalpel technique offers a favorable safety and efficiency profile for vasectomy procedures.
