Insights
This study compares pediatric urolithiasis treatments, finding percutaneous nephrolithotomy (PCNL) and extracorporeal shockwave lithotripsy (SWL) highly effective for stone removal in children.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
- Nephrolithiasis Management
Background:
- Pediatric urolithiasis management involves challenging endourologic techniques.
- Selecting the appropriate minimally invasive modality is crucial for successful outcomes.
Purpose of the Study:
- To analyze the outcomes of different endourologic techniques for pediatric urolithiasis.
- To evaluate the effectiveness of selected techniques based on established guidelines.
Main Methods:
- Prospective analysis of percutaneous nephrolithotomy (PCNL), ureteroscopy (URS), and extracorporeal shockwave lithotripsy (SWL).
- Study included 45 children (35 boys, 10 girls) aged 12 months to 17 years.
- Outcomes assessed included stone-free rate, complications, and hospital stay.
Main Results:
- Extracorporeal shockwave lithotripsy (SWL) achieved a 92.3% stone-free rate in 13 children.
- Percutaneous nephrolithotomy (PCNL) had a 95.8% stone-free rate, with 80% completed in a single stage.
- Rigid ureteroscopy (URS) was successful in 66.7% of planned procedures.
Conclusions:
- Judicious use of minimally invasive techniques can effectively treat most pediatric stone disease cases.
- Proper treatment planning is essential for optimal patient outcomes.
- An algorithm for managing pediatric stone disease is recommended based on study findings.
Background And Purpose:
Pediatric urolithiasis can be managed with various endourologic techniques, which are challenging and demanding. With the availability of advanced minimally invasive techniques, one has to select the appropriate modality. We analyzed the results of various techniques selected prospectively on the basis of our guidelines for the management of pediatric urolithiasis.
Patients And Methods:
We analyzed the results of percutaneous nephrolithotomy (PCNL), ureteroscopy (URS), and extracorporeal shockwave lithotripsy (SWL) in 45 children treated at our institute between January 2004 and May 2005. There were 35 boys and 10 girls ranging from 12 months to 17 years age (median age 8.2 +/- 5.72 years), with 25 children (55.6%) under the age of 8 years. Stone-free rate, complications, and hospital stay were assessed.
Results:
Extracorporeal lithotripsy was performed in 13 children (15 renal units) with average stone surface area of 50.8 +/- 35.8 mm(2). The stone-free rate was 92.3%. The total number of shocks per treatment ranged from 450 to 1400 (mean 856.3 +/- 189.6). A total of 25 PCNLs were done. Stone extraction was completed in a single stage in 20 units (80%), whereas 5 units (20%) required a second stage. Stone-free status was achieved in 23 renal units (95.8%). In the URS group, 9 procedures were planned in 8 children, and rigid ureteroscopy was successful in 6 (66.7%).
Conclusions:
With the availability of various alternative approaches, proper treatment planning and judicious use of minimally invasive techniques can cure most patients. On the basis of our experience and results, we recommend an algorithm for the management of pediatric stone disease.
