I don't know if this comment is intended seriously but just to be clear. Lithotripsy can cause acute tissue damage and long-term loss of kidney function.[1] The shock waves need to be carefully targeted at the stone and for the correct amount of time to reduce the risk of this, typically with X-ray or ultrasound. You can absolutely not do this at home!
