Simplifying vasectomy reversal without compromising outcomes: a single-surgeon series.

Area of Science:

• Urology
• Microsurgery
• Reproductive Medicine

Background:

• Microsurgical vasovasostomy (VV) offers superior outcomes compared to macroscopic or loupe-assisted techniques.
• The optimal number of anastomosis layers (single vs. double) for VV remains debated, despite the popularity of two-layer methods.
• This study evaluates a simplified single-layer microsurgical VV technique.

Purpose of the Study:

• To assess the outcomes of a simplified single-layer microsurgical vasovasostomy (VV) technique.
• To compare the results of this technique with existing two-layer methods.
• To identify predictive factors for successful VV outcomes.

Main Methods:

• Retrospective analysis of 237 patients undergoing microsurgical VV from 2010-2022.
• A single-layer, six-point, 8-0 nylon anastomosis was performed.
• Intraoperative assessment of vasal fluid and postoperative semen analysis at 3 months.

Main Results:

• An overall patency rate of 85.8% was achieved.
• Obstructive intervals significantly impacted patency rates (P=0.04).
• No difference in patency was observed between straight vs. convoluted vas or unilateral VV.

Conclusions:

• A simplified single-layer microsurgical VV technique yields outcomes comparable to complex two-layer methods.
• Reduced ischemia and tissue handling may contribute to the success of the single-layer technique.
• The single-layer technique offers potential advantages in terms of time, cost, and learning curve for routine practice.
