    Summary

    This study presents a novel partial nephrectomy technique minimizing kidney injury and blood loss without clamping the renal pedicle. The method utilizes continuous U-shaped sutures for effective hemostasis and parenchyma closure, leading to favorable patient outcomes.

    Area of Science:

    • Urology
    • Surgical Innovation
    • Nephrology

    Background:

    • Partial nephrectomy is crucial for kidney preservation.
    • Traditional methods may cause significant renal injury and blood loss.
    • Minimally invasive techniques are continuously sought to improve outcomes.

    Purpose of the Study:

    • To describe a novel partial nephrectomy technique.
    • To evaluate its efficacy in minimizing kidney injury and blood loss.
    • To assess outcomes without pedicle clamping or hypothermia.

    Main Methods:

    • A continuous U-shaped suture technique using chromic catgut was employed for virtual and total hemostasis.
    • Renal parenchyma excision was performed between two parallel U-shaped sutures.
    • Raw surfaces were reapproximated with continuous sutures, followed by temporary nephrostomy.

    Main Results:

    • The technique was applied to 112 consecutive patients over 12 years.
    • Minimizes injury to the kidney and avoids unnecessary blood loss.
    • No interruption of arterial or venous blood flow during surgery was necessary.

    Conclusions:

    • The described partial nephrectomy technique offers a safe and effective approach.
    • It successfully minimizes renal parenchyma injury and blood loss.
    • The technique demonstrates favorable short- and long-term outcomes in a large patient cohort.
