<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had kidney stones in the past and have not been feeling well,I went to the dr then I went to get xrays I went to hospital to get the typed report it says I have a 2mm density over the lower pole of the right kidney and additional calculi noted in the kidneys or along the expected course of the kidney.and a few rounded denisitiess in the anatamotic pelvis likely represent phleboliths. what does all that mean in English?? my back has really been bothering me and I cannot seem to get comfortable.  <response>: Hi, Density is therm applied for appearance of tissue on x-ray. In simple word hyper-dense means white on x-ray and hypo-dense means black on x-ray. But most of the time only word density is used, and it means hyper-density.2 mm density over the lower pole of the right kidney and additional calculi noted in the kidneys or along the expected course of the kidney it means - There is one 2 mm calculus stone at lower end of right kidney maybe in ureter - tube connecting kidney to urinary bladder urine bagand some additional more, number not specified stones at the possible location of right kidney. Pelvis : it is a part of kidney from where ureter tube connecting kidney to urinary bladder urine bag originate and blood vessels enter the kidney. Phleboliths : it means stones in veins blood vessels that carries blood away from kidney to Inferior vent cave which is a big blood vessel which carries blood from lower half of body to heart Back pain in your case is due to kidney stone.
