Kidney stones: The question is why are you taking vitamin d and calcium (c) at all? Your stones could certainly be due to taking those agents. Have a physician order a 24 hour urine collection for uric acid, c and phosphorus levels. If your calcium is high in it, you may need to be on diuretics to reduce the c there. Have a doctor discuss with you the reasons you should or should not be on vit d and c. Good luck. ...Read more

My friend is wanting to know if its dangerous to have small kidneys? She has been having a lot of back pain, chills and  shortness of breath.

Lungs?: Kidneys vary in size a little. What do you mean small and why are they small? If she has a chronic kidney disease and her kidneys are small as a result of that it could be related to her current symptoms. If she has mildly small kidneys and normal function this is not likely relatedat all. I wonder if her symptoms are more related to her lungs which can produce pain, chills and short breath. ...Read more

Do you know if a small size kidney on left would cause a lot of pain? I have pain always in the left side back around kidney. Have 2 cyst inside.

Kidney pain is usually caused by distension of the renal capsule, as in stones, infection, and masses causing obstruction are the most common reasons. Trauma of the kidney can also cause pain. Enlarged renal cysts may also refer pain to the back. A exam +/- MRI would help clear up the diagnosis. ...Read more

Just found out I have a small myelolipoma on my R kidney. Can that cause any problems? Does it trigger hormone release like excessive growth hormones?

Just found out I have a small myelolipoma on my R kidney. Can that cause any problems? Does it trigger hormone release like excessive growth hormones?

Rare and benign: myelolipoma of the kidney is a rare and benign lesion usually of adrenal but sometimes found in the kidney. If it enlarges in the kidney it may compress the hilum to produce hydronephrosis and in even rarer cases may have a liposarcomatous component. There are no reported cases of producing hormone and would never induce production of growth hormone which is of pituitary origin. ...Read more

I have 4 "tiny" stones 2 in each kidney and a very small cyst. I get bad kidney pain sometimes. Can this be caused if stones aren't in ureter?

I have 4 "tiny"  stones 2 in each kidney and a  very small cyst. I get bad kidney pain sometimes. Can this be caused if stones aren't in ureter?

No: Non-obstructing stones or a small cyst will not cause pain in the kidney. Kidney pain typically results from distention of the renal capsule when the stones move into the ureter. Pain usually occurs during acute obstruction. Cysts in the kidney only cause pain when there is hemorrhage into a cyst or very rarely do they cause blockage of the drainage from the kidney. ...Read more

Will a small kidney stone cause pain?

Ureteral stone: The size of the stone does not correlate well to the intensity of the pain. The nearly unbearable pain of "ureteral colic" is from spasm of the muscular ureter. Although likely to pass on its own within a few days, a 2-3mm stone sometimes will get stuck and fail to progress. Usually after 5 days, i recommend having the stone extracted with a ureteroscope as an outpatient. ...Read more
