Summary

Laparoscopic-assisted tubeless percutaneous nephrolithotomy (PNL) is optimal for complex ectopic kidney stones. This technique offers a high stone-free rate and potentially shorter hospital stays for urolithiasis treatment.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrolithiasis Management

Background:

  • Complex urolithiasis in ectopic kidneys presents unique treatment challenges due to variable anatomical locations.
  • Conventional approaches may be insufficient, necessitating tailored surgical strategies.

Purpose of the Study:

  • To review developed techniques for treating complex urolithiasis in ectopic kidneys.
  • To evaluate the efficacy of laparoscopic-assisted tubeless, transhepatic, and transiliac percutaneous nephrolithotomy (PNL).

Main Methods:

  • Retrospective analysis of patients with congenital pelvic kidneys undergoing PNL.
  • Procedures included laparoscopic-assisted tubeless PNL (n=6), transiliac PNL (n=1), and transhepatic PNL (n=1).
  • Laparoscopic procedures utilized internalized ureteral stents without drainage tubes.

Main Results:

  • All PNL procedures were successful.
  • Laparoscopic-assisted PNL achieved a 100% stone-free rate postoperatively.
  • Transiliac and transhepatic PNL required secondary procedures for complete stone removal.
  • Mean hospital stay was 3 days for laparoscopic-assisted and transiliac PNL, and 1 day for transhepatic PNL.

Conclusions:

  • Laparoscopic-assisted tubeless PNL is the preferred treatment for large or complex stones in ectopic kidneys.
  • Performing PNL tubeless may reduce hospital stays.
  • Individualized approaches are recommended for patients with a history of abdominal surgery.
