Percutaneous nephrolithotripsy (PCNL) effectively treated kidney stones in 64 patients. Most patients were stone-free after PCNL, with minimal complications and short hospital stays.

Area of Science:

  • Urology
  • Nephrology
  • Surgical Procedures

Background:

  • Kidney stones, particularly large renal or staghorn calculi, pose a significant clinical challenge.
  • Percutaneous nephrolithotripsy (PCNL) is an established minimally invasive surgical option for stone removal.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of percutaneous nephrolithotripsy (PCNL) for treating renal and ureteric stones.
  • To assess the stone-free rates, operative time, hospital stay, and complication profile of PCNL.

Main Methods:

  • A consecutive series of 68 PCNL procedures were performed on 64 patients over a 14-month period.
  • The study included patients with large renal, staghorn, and ureteric stones, with all procedures performed as a single stage.

Main Results:

  • 41% of patients were stone-free after PCNL alone; 86% achieved stone-free status at three months follow-up.
  • Residual fragments required extracorporeal shockwave lithotripsy (ESWL) in 38 cases.
  • Mean operative time was 109.6 minutes, and mean hospital stay was 4.5 days, with minor complications in 6 patients.

Conclusions:

  • PCNL is an effective treatment for renal and ureteric stones, achieving high stone-free rates with a low complication rate.
  • A significant proportion of patients may require adjunctive ESWL for complete stone clearance.
  • The procedure is associated with acceptable operative times and short hospitalizations.
