Extracorporeal shock wave lithotripsy: indications and technique

Area of Science:

• Urology
• Nephrology
• Minimally Invasive Surgery

Background:

• Kidney stones (renal calculi) pose a significant health burden, often requiring invasive surgical interventions.
• Traditional stone removal methods carry substantial morbidity and risk.
• There is a need for safer and more effective treatments for urolithiasis.

Purpose of the Study:

• To evaluate the efficacy and safety of a new method for treating kidney stones.
• To compare the morbidity and risk of this new method with existing stone removal techniques.
• To assess the potential of extracorporeal shock wave lithotripsy (ESWL) in reducing surgical interventions for stones.

Main Methods:

• Utilized extracorporeal shock wave lithotripsy (ESWL) as a primary treatment modality.
• Assessed the short-term morbidity and risk associated with ESWL.
• Analyzed the percentage of stones treatable by ESWL compared to surgical removal.
• Investigated the combined use of ESWL with endoscopic procedures.

Main Results:

• The new ESWL method demonstrated one-tenth the morbidity and risk of comparable stone removal techniques in the short term.
• ESWL is effective in treating 70% to 80% of stones that would otherwise necessitate surgery.
• Combining ESWL with endoscopic procedures reduced the need for open surgical procedures to less than 1% of patients.

Conclusions:

• ESWL represents a significant advancement in kidney stone treatment, offering substantially lower morbidity and risk.
• The combination of ESWL and endoscopic procedures greatly minimizes the need for open surgery.
• Despite treatment advancements, metabolic evaluation and prevention strategies for kidney stone disease remain crucial.
