Percutaneous nephrolithotomy (PCNL) using ureteroscopy and pneumatic lithotripsy is safe and effective for pediatric kidney stones. This minimally invasive procedure achieved a 91% stone-free rate in children under 14.
Area of Science:
- Urology
- Pediatric Surgery
- Minimally Invasive Procedures
Context:
- Pediatric urolithiasis presents unique challenges.
- Percutaneous nephrolithotomy (PCNL) is an established treatment for kidney stones.
- Advancements in technology allow for minimally invasive approaches in children.
Purpose:
- To evaluate the safety and efficacy of PCNL with ureteroscopy and pneumatic lithotripsy in pediatric patients.
- To determine the stone clearance rate and complication profile of this technique in children.
- To assess the feasibility of this approach for various stone burdens, including staghorn calculi.
Summary:
- A study involving 15 pediatric patients (22 renal units) with kidney stones, including bilateral, multiple, and staghorn calculi, was conducted.
- Percutaneous nephrolithotomy (PCNL) was performed using X-ray guidance, minimal tract dilation, ureteroscopy, and pneumatic intracorporeal lithotripsy.
- Complete stone clearance was achieved in 91% of cases, with minor pyrexia in 14 patients and no blood transfusions required.
Impact:
- This study demonstrates that PCNL with ureteroscopy and pneumatic lithotripsy is a safe and effective treatment option for pediatric kidney stones.
- The findings support the use of this minimally invasive technique for achieving high stone-free rates in children.
- This approach offers a viable solution for complex pediatric urolithiasis, potentially reducing morbidity associated with open surgery.
