Summary
Extracorporeal shock wave lithotripsy (ESWL) effectively treats pediatric urolithiasis, with stone size significantly impacting stone-free rates. Different lithotripters showed varied re-treatment rates but similar stone-free outcomes.
Area of Science:
- Pediatric Urology
- Nephrology
- Surgical Technology
Background:
- Urinary stone disease (urolithiasis) affects children, necessitating effective treatment options.
- Extracorporeal shock wave lithotripsy (ESWL) is a non-invasive modality for managing pediatric urolithiasis.
Purpose of the Study:
- To evaluate the efficacy of ESWL in treating pediatric urolithiasis.
- To identify factors influencing treatment outcomes, including stone-free rates and re-treatment needs.
Main Methods:
- A cohort of 148 children and adolescents with renal or ureteric stones were treated using two types of lithotripters.
- Patients were assessed three months post-treatment.
- Statistical analysis (chi-square test) was employed to determine factors associated with stone-free rates.
Main Results:
- The overall stone-free rate for renal stones was 86%, with a 64% re-treatment rate.
- Stone transverse diameter was a significant factor affecting the stone-free rate (P = 0.012).
- All ureteric stones were cleared, with minimal re-treatment required; complications were rare.
Conclusions:
- ESWL is a safe and effective treatment for pediatric urolithiasis.
- Stone size is a critical determinant of ESWL success.
- While lithotripter type influenced re-treatment rates, it did not significantly affect the stone-free rate.
