Bilateral simultaneous percutaneous nephrolithotomy (BPNL) is feasible and safe for treating kidney stones. This procedure, performed under single anesthesia, achieved high stone clearance rates with minimal complications.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Upper tract urolithiasis presents a significant clinical challenge.
  • Percutaneous nephrolithotomy (PNL) is a standard treatment for large kidney stones.
  • Bilateral simultaneous PNL (BPNL) offers a potentially more efficient approach for bilateral stones.

Purpose of the Study:

  • To evaluate the feasibility and safety of performing bilateral simultaneous percutaneous nephrolithotomy (BPNL) under a single anesthetic session.
  • To assess the technical aspects, operative time, and outcomes of BPNL.

Main Methods:

  • A prospective study involving 16 consecutive patients with bilateral upper tract urolithiasis.
  • Bilateral simultaneous PNL was attempted, with patient repositioning for contralateral access.
  • Data on operative time, stone clearance, complications, and hospital stay were collected.

Main Results:

  • BPNL was successfully completed in 14 out of 16 patients (87.5%).
  • Average operative time was 83 minutes, with no significant intraoperative morbidity.
  • Complete stone clearance was achieved in 11 patients (78.6%), with 2 requiring additional treatments.

Conclusions:

  • Bilateral simultaneous PNL is a feasible and safe procedure for selected patients with bilateral upper tract stones.
  • With appropriate training and setup, BPNL can be efficiently performed under a single anesthesia.
  • The study suggests BPNL is advisable for patients with bilateral stones after achieving proficiency in standard PNL.
