Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Laparoscopic nephroureterectomy and ureterectomy are standard procedures.
  • Effective bladder cuff management is crucial for preventing complications.

Purpose of the Study:

  • To evaluate the safety and efficacy of a gastrointestinal anastomosis stapling device for bladder cuff closure during laparoscopic nephroureterectomy and ureterectomy.

Main Methods:

  • A gastrointestinal anastomosis stapling device delivering titanium staples was used.
  • The device was initially tested in 8 female pigs undergoing laparoscopic nephroureterectomy.
  • Subsequently, 3 human patients underwent laparoscopic ureterectomy using the stapler for ureteral and bladder cuff transection.

Main Results:

  • No complications such as extravasation, stone formation, urinary tract infection, or abscess formation were observed.
  • Follow-up in animal models ranged from 2 to 6 months postoperatively.
  • The stapling device provided rapid and secure closure of the bladder cuff in all cases.

Conclusions:

  • Titanium staples offer a safe and effective method for bladder cuff closure in laparoscopic nephroureterectomy and ureterectomy.
  • This technique may reduce operative time and improve patient outcomes.
  • Further studies are warranted to confirm long-term efficacy.
