HI, I have a 1CM Kidney Stone that's in my ureter. It's on my right side but I've not had any pain at all. How dangerous is this?

Dangerous: The ureter is blocked by the stone and it is causing back pressure into the kidney. If not relieved, the back pressure will destroy the kidney. You do not have pain because the stone is too big to move. Please see a urologist at your earliest. ...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

What can happen if i don't have a kidney stone removed from ureter?

What can happen if i don't have a kidney stone removed from ureter?

Pass or obstruct.: A stone in the ureter may pass or it may obstruct the ureter. The likelihood that a stone will pass decreases significantly the larger it is, especially over 5mm. If the stone fails to pass, obstruction of urine can cause the kidney to swell in a process called hydronephrosis. Over time this can lead to increased risk of infection and kidney atrophy. Work with your urologist for options. ...Read more

I had a kidney stone before but it was passed before 10days, but there is slightly pain left in my kidney or may b in ureter. i don't knw the reason ?

Stone: I would suggest a urinalysis and an exam to make sue you don't have a UTI. You may need an X-ray to make sure it's not a new or residual stone. Also you should have a CT Urogram or IVP if you've never had one to make sure there are no anatomical issues. ...Read more
