Summary

Percutaneous nephrolithotomy (PCN) is recommended for renal calculi larger than 2 cm, as extracorporeal shock wave lithotripsy (ESWL) is less effective for these larger stones. PCN offers a viable alternative for complex cases.

Area of Science:

  • Urology
  • Nephrology
  • Surgical Interventions

Background:

  • Extracorporeal shock wave lithotripsy (ESWL) has altered the landscape of renal lithiasis treatment.
  • Percutaneous nephrolithotomy (PCN) remains a crucial intervention for specific cases of kidney stones.

Purpose of the Study:

  • To analyze current indications for PCN in renal lithiasis treatment.
  • To highlight the role of stone size in treatment decisions.
  • To discuss challenges associated with PCN.

Main Methods:

  • Analysis of current indications for PCN.
  • Focus on stone size as a primary criterion.
  • Review of challenges in specific patient populations and stone types.

Main Results:

  • Calculi greater than 2 cm are best treated with PCN.
  • ESWL achieves complete stone clearance in only 15-20% of patients with large calculi after one session.
  • PCN is indicated for staghorn calculi.

Conclusions:

  • Stone size is a critical factor in selecting PCN over ESWL for renal lithiasis.
  • PCN is effective for large calculi and staghorn stones.
  • Challenges exist for PCN in pediatric, obese, and renoureterally compromised patients, and for hard cystine calculi.
