Pediatric urolithiasis: to cut or not to cut

Area of Science:

• Pediatric Urology
• Surgical Technology
• Nephrology

Background:

• Urolithiasis is a significant health issue in children, particularly in developing nations.
• Extracorporeal shock wave lithotripsy (ESWL) has become a common treatment for kidney stones since 1982, despite unknown long-term kidney effects.
• Traditional open surgery was the primary method before ESWL's widespread adoption.

Purpose of the Study:

• To compare the effectiveness and outcomes of ESWL versus open surgery for pediatric urolithiasis.
• To evaluate stone clearance rates, complications, follow-up duration, and treatment costs for both methods.
• To provide guidance on the appropriate use of ESWL in pediatric stone management.

Main Methods:

• A retrospective study comparing ESWL and open surgery for pediatric urolithiasis (patients under 14 years).
• Data collected from November 1988 to December 1991 at a single institution.
• Analysis focused on stone location (kidney, ureter, bladder), clearance rates, complications, follow-up adherence, and cost.

Main Results:

• ESWL treated 44 calculi in 31 patients with an 82% overall stone clearance rate (83% for renal stones).
• Open surgery treated 57 stones in 52 patients with a 96% overall stone clearance rate (88% for renal stones).
• ESWL had significant patient loss to follow-up (93.5% after 6 months) and higher mean cost ($780) compared to open surgery ($580). Open surgery had minor complications like wound infections.

Conclusions:

• Open surgery demonstrated a higher stone clearance rate and lower cost compared to ESWL in this pediatric cohort.
• Significant loss to follow-up in the ESWL group raises concerns about long-term outcomes.
• ESWL should be reserved for children with small stones or those with guaranteed long-term follow-up, given current knowledge.
