Right kidney stone 5mm size is a small stone in the kidney, it is recommended to drink more water, urinate more, and have regular ultrasound review of the urinary system, and no medication, extracorporeal shock wave lithotripsy or surgery is needed for the time being. Most of the stones can be discharged through the ureter, but in a very small number of patients, the stones may be located in the renal calyces or in a small calyx and cannot be discharged. This is usually done in patients whose stones have gradually increased in size during the observation period and have not moved. If the size of the stone is more than 6 mm, and there is fluid in the kidney, and the amount of fluid is further increased, then extracorporeal shock wave lithotripsy is needed. If there is no change in stone size during the review, it is sufficient to drink more water, exercise more and urinate more to promote stone discharge.
