Summary

This randomized controlled clinical study compared supine mini percutaneous nephrolithotomy versus flexible ureteroscopy for the management of dense lower calyceal renal stones measuring 1-2 centimeters (≤20 millimeters) with stone density greater than 1000 Hounsfield units in school-age pediatric patients aged 6-12 years. Participants were randomized to undergo either supine mini percutaneous nephrolithotomy with laser lithotripsy or flexible ureteroscopy with laser lithotripsy. The study assessed stone-free rate on non-contrast computed tomography of the urinary tract at 1 month postoperatively, along with operative time, fluoroscopy time, intraoperative and postoperative complications, and length of hospital stay. The trial has ended.

Conditions

  • Nephrolithiasis
  • Kidney Calculi
  • Urolithiasis

Interventions

PROCEDURE

Supine Mini Percutaneous Nephrolithotomy

Percutaneous renal access and tract dilation to mini size in the supine position, followed by endoscopic stone fragmentation using laser lithotripsy, with ureteral stent placement and nephrostomy tube placement per protocol.

PROCEDURE

Flexible Ureteroscopy

Retrograde endoscopic access to the kidney using a flexible ureteroscope with laser lithotripsy for stone fragmentation, followed by ureteral stent placement per protocol.
