Summary

Percutaneous nephrolithotomy (PCNL) complications were reduced by an occlusive catheter technique. This innovation minimizes stone fragment migration, improving surgical outcomes and reducing operative time for kidney stone removal.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Percutaneous nephrolithotomy (PCNL) is a common procedure for kidney stone removal.
  • Fragment migration into inaccessible calices is a significant challenge during PCNL, prolonging operative time and potentially requiring repeat procedures.

Purpose of the Study:

  • To describe modifications to PCNL aimed at preventing stone fragment migration.
  • To evaluate the efficacy of these modifications in reducing operative time and improving stone clearance.

Main Methods:

  • A novel occlusive catheter was introduced into the renal collecting system to close caliceal orifices during PCNL.
  • In cases of multiple stones, simultaneous dual-tract access and alternating nephroscope use were employed.
  • Ultrasonic lithotripsy was utilized for stone fragmentation.

Main Results:

  • The occlusive catheter technique effectively prevented stone fragment migration into upper and lateral calices.
  • Simultaneous dual-tract access facilitated efficient management of multiple stones.
  • The modifications significantly reduced operative time and increased the overall effectiveness of PCNL.

Conclusions:

  • The described modifications, particularly the occlusive catheter, represent a valuable advancement in PCNL.
  • These techniques enhance stone removal efficiency and reduce procedural complications, offering improved patient outcomes.
