Extracorporeal shock wave lithotripsy in children

Area of Science:

• Pediatric Urology
• Nephrolithiasis Treatment
• Extracorporeal Shock Wave Lithotripsy

Background:

• Urinary calculi in children present unique treatment challenges.
• Extracorporeal shock wave lithotripsy (ESWL) is a non-invasive option for stone removal.
• Assessing ESWL efficacy in pediatric populations is crucial for guiding treatment decisions.

Purpose of the Study:

• To evaluate the success rate and outcomes of extracorporeal shock wave lithotripsy (ESWL) in pediatric patients.
• To identify factors influencing ESWL success in children with urinary calculi.
• To determine the suitability of ESWL as a first-line treatment for pediatric nephrolithiasis.

Main Methods:

• Retrospective review of 103 pediatric patients treated with ESWL.
• Analysis of stone characteristics (size, number) and their correlation with treatment outcomes.
• Assessment of short-term complications and hospitalization duration.

Main Results:

• The overall success rate for ESWL in children was 63%.
• Stone volume was a critical factor, with decreasing success rates as stone size increased.
• Higher stone burden (increased number of stones) correlated with lower stone-free rates.
• Short-term complications were minimal, and hospital stays were brief.

Conclusions:

• ESWL demonstrates a favorable success rate in pediatric patients with urinary calculi.
• Stone size (under 200 mm2) and number are significant predictors of ESWL outcomes.
• ESWL is recommended as a primary treatment modality for appropriately selected pediatric urinary stones.
