How Is Lithotripsy Performed?
The Lithotripsy machine creates shock waves, which are a form of high-pressure energy. The waves travel through water and body tissue, hit the stone, then scatter and break it up. The patient usually passes the residual sand-like particles in the urine. This procedure is associated with minimal discomfort. Lithotripsy alone can treat 70 to 80% of patients with kidney stones, however 20 to 30% of patients need further treatment because their stones are too large, or too hard to be broken. They may also have anatomic abnormalities which prevent the passing of the fragments. Additional procedures or a repeat lithotripsy treatment may be needed to totally eliminate stone fragments. You will be in the unit approximately two hours. An IV will be started to supply fluids and medications during the procedure. The procedure takes 20 to 40 minutes followed by one hour for recovery. You may bring a CD or cassette tape to listen to during the procedure.
