Laparoscopic pyeloplasty with pyelolithotomy effectively removes kidney stones during ureteropelvic junction repair. This minimally invasive approach offers stone-free rates comparable to open surgery.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Endourology

Background:

  • Ureteropelvic junction (UPJ) obstruction can coexist with renal calculi.
  • Traditional management often involves separate procedures for obstruction and stones.
  • Laparoscopic techniques offer potential advantages in treating complex urological conditions.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of combining laparoscopic pyeloplasty with pyelolithotomy.
  • To assess the efficacy of this combined approach in patients with UPJ obstruction and stones.

Main Methods:

  • A transperitoneal laparoscopic approach was used for pyeloplasty and pyelolithotomy in 19 patients (20 renal units).
  • Stones were extracted via a small pyelotomy before UPJ repair, using graspers and a flexible cystoscope.

  • Renal pelvis reconstruction was tailored to the specific UPJ anatomy.

    • Main Results:

    • A median of 1 stone (range 1-28) was removed per patient.
    • The procedural stone-free rate was 90% at 3 months, with 90% of patients free of obstruction.
    • The overall long-term stone-free rate was 80% at a mean follow-up of 12 months.

    Conclusions:

    • Laparoscopic pyelolithotomy is a feasible adjunct to laparoscopic pyeloplasty for managing UPJ obstruction with stones.
    • Outcomes are comparable to open pyeloplasty or percutaneous endopyelotomy.
    • This minimally invasive strategy preserves the benefits of open surgery.
