Key Facts

• Two types: intracorporeal laser lithotripsy (lower tract) and extracorporeal shock wave lithotripsy (upper tract)
• Laser lithotripsy: holmium:YAG laser via cystoscope; fragments bladder/urethral stones
• Not possible in male cats or small male dogs (urethra too narrow for cystoscope)
• Laser success rate: 83-96% in female dogs, 68-81% in male dogs
• Extracorporeal: shock waves fragment kidney/ureteral stones; 85% success in dogs
• Calcium oxalate stones respond well to extracorporeal lithotripsy in dogs (not cats)
• Advantages: same-day discharge, less invasive, no cutting
• Disadvantages: requires specialized equipment, limited availability, more expensive than surgery
• Not efficient for numerous stones (>5) or very large stones
• Species: dogs and cats (limited in males)
