Kidney stones are a common type of urinary stone. Simple kidney stones usually do not affect the color of the urine, which can be pale yellow. When kidney stones are combined with a urinary tract infection, they can increase the impurity content of the urine and can make the urine cloudy. If the stones irritate the mucous membrane of the renal pelvis and bleed, it will increase the red blood cells in the urine and cause hematuria to occur. Patients with kidney stones should be given treatment as soon as possible according to the size of the stone and choose a reasonable treatment plan to avoid symptoms such as pain and hematuria due to the stone staying in the urinary tract for a long time. At present, the treatment for kidney stones can be done by extracorporeal shock wave lithotripsy or by percutaneous nephrolithotripsy for stone extraction.
