Percutaneous nephrolithotomy (PCNL) is safe and effective for treating kidney stones in pelvic ectopic kidneys. This minimally invasive procedure achieved complete stone clearance in all patients, demonstrating its viability for complex cases.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Percutaneous nephrolithotomy (PCNL) is established for normal kidneys but underutilized for pelvic ectopic kidneys due to perceived risks.
  • Abdominal organ injury is a significant concern, limiting widespread adoption of PCNL in these cases.

Purpose of the Study:

  • To evaluate the safety and efficacy of PCNL for treating kidney stones in pelvic ectopic kidneys.
  • To identify key technical factors contributing to successful PCNL in this challenging anatomical location.

Main Methods:

  • Nine patients with pelvic ectopic kidney stones underwent PCNL.
  • Key techniques included ultrasound-guided puncture, mature tract or Amplatz sheath use, and routine postoperative double-J stenting.
  • Nephrostogram was performed before nephrostomy tube removal.

Main Results:

  • Complete stone clearance was achieved in all nine patients.
  • Most patients (7/9) required a single tract, and 6/9 were treated in a single stage.
  • No significant complications were observed, with an average hospital stay of 5.2 days.

Conclusions:

  • PCNL is a safe and effective treatment for calculi in pelvic ectopic kidneys.
  • Meticulous technique and specific precautions enable successful outcomes in these complex cases.
