Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Endourology

Context:

  • Ureteropelvic junction (UPJ) stenosis is a common cause of upper urinary tract obstruction.
  • Antegrade endopyelotomy is an established treatment, but incision techniques can be refined.
  • Laparoscopic approaches offer advantages in precision and visualization.

Purpose:

  • To evaluate the safety and efficacy of a novel technique for antegrade endopyelotomy using modified laparoscopic scissors.
  • To assess the feasibility of performing the incision through a nephroscope with specialized instruments.

Summary:

  • Modified 3 mm laparoscopic scissors were used for antegrade endopyelotomy in 18 patients with UPJ obstruction (12 primary, 6 secondary).
  • The technique involves a small puncture and controlled opening of the scissors under endoscopic visualization, allowing for precise cutting and management of small vessels.

  • The procedure resulted in a 94% success rate, with minimal operative time, blood loss, and rapid hospital discharge.

    • Impact:

    • This modified technique offers a precise and safe alternative for antegrade endopyelotomy.
    • It potentially reduces operative time and improves patient recovery compared to conventional methods.
    • The ability to visualize and manage vascular structures during the incision enhances procedural safety.
