In general, the patient is advised to drink large quantities of clean water, and painkillers are also given to him. The doctor may prescribe antibiotics for the patient to treat urinary tract infection. The aim of these procedures is to try to push the stone out and get rid of it, but the problem lies in the large stones in size. The doctor decides to perform lithotripsy by ultrasound from outside the body or lithotripsy by laser by entering through the urethra to the stone. In some cases where the kidney stone is large and of high density, the stone is removed surgically with a process called nephrostomy, where the surgeon enters directly into the patient’s kidney through the flank wall and surgically removes the stone.
