A novel laparoscopic stylet, designed for kidney stone removal, facilitates the mobilization and extraction of ureteral and renal pelvis calculi. This modified chromium nickel instrument has proven effective in retroperitoneoscopic ureterolithotomy, indicating potential for laparoscopic pyelolithotomy.

Area of Science:

  • Urology
  • Surgical Instrumentation
  • Minimally Invasive Surgery

Background:

  • Kidney stones (ureteral and renal pelvis calculi) pose a significant clinical challenge.
  • Traditional methods for stone extraction can be invasive.
  • Laparoscopic surgery offers a minimally invasive approach for stone removal.

Purpose of the Study:

  • To describe a new instrument, the laparoscopic stylet, for extracting ureteral and renal pelvis calculi.
  • To evaluate the utility of the laparoscopic stylet in retroperitoneoscopic ureterolithotomy.

Main Methods:

  • Development of a laparoscopic stylet from chromium nickel, modifying a classical stylet design.
  • Application of the instrument in 11 retroperitoneoscopic ureterolithotomy operations.

Main Results:

  • The laparoscopic stylet was successfully used for mobilizing and extracting calculi from the ureters.
  • The instrument demonstrated significant utility in the performed procedures.

Conclusions:

  • The newly developed laparoscopic stylet is effective for the laparoscopic extraction of ureteral calculi.
  • The instrument shows promise for application in laparoscopic pyelolithotomy procedures for renal pelvis calculi.
