    Summary

    This study determined optimal suture sizes and modified instruments for two-layer vas reversal. A new technique was developed to enable single-surgeon vas reversal procedures.

    Area of Science:

    • Urology
    • Surgical Techniques
    • Microsurgery

    Background:

    • Vas reversal is a microsurgical procedure to restore patency of the vas deferens.
    • Existing techniques may require specialized equipment or multiple surgeons, posing challenges.

    Purpose of the Study:

    • To optimize suture selection for each layer in two-layer vas reversal.
    • To adapt existing surgical instruments for improved vas reversal efficacy.
    • To develop a simplified technique for performing vas reversal as a solo surgeon.

    Main Methods:

    • Investigated appropriate suture sizes for the inner and outer layers of the vas deferens during reversal.
    • Modified standard microsurgical instruments to enhance maneuverability and precision for vas reversal.
    • Devised and tested a novel surgical approach facilitating single-operator vas reversal.

    Main Results:

    • Established specific suture size recommendations for accurate mucosal and muscular layer approximation.
    • Successfully adapted instruments, improving ease of use and surgical outcomes in vas reversal.
    • Validated a technique allowing a single surgeon to efficiently complete the vas reversal procedure.

    Conclusions:

    • The study provides evidence-based guidelines for suture selection in two-layer vas reversal.
    • Instrument modifications and the developed technique enhance the feasibility and efficiency of vas reversal surgery.
    • The findings support the adoption of a single-surgeon approach for improved accessibility of vas reversal procedures.
