I have a 7 mm kidney stone will it pass on its on or will it get stuck? I'm due to fly in aweek scared with the stone!

Depends: Is it still a kidney stone of has it passed into the ureter and is now an ureteral stone? If it is just sitting in the kidney it will probably stay there for some indeterminate time, maybe, "forever". If in the ureter, it can cause pain and blood in the urine as it makes it way down. The chances of stone passage for stones 5-7 mm, 60%; for stones 7-9 mm, 48%.
Good luck. ...Read more

I am flying in 2 weeks with a 4mm kidney stone which is in the bottom of my kidney. Minimal to no pain. Will the flight altitude make the stone move?

I am flying in 2 weeks with a 4mm kidney stone which is in the bottom of my kidney. Minimal to no pain. Will the flight altitude make the stone move?

No, but...: Changing altitude will not alter the odd for this 4-mm stone to move, but its timing of moving and dropping is entirely unpredictable so air pilots are advised to be stone-free. As to air passengers, it is up to their choice and risk. Besides, personal past history of stone disease may be a good reference to project how possible a stone in kidney may move, but still not 100% certain. Best wish ... ...Read more

Is it safe to fly with kidney stones?

Is it safe to fly with kidney stones?

That's fine.: Meaning it's not that high altitude or pressurized cabins will make kidney stones more likely to pass. However, I don't think you'd want a stone to coincidentally get stuck while trying to pass while you were in an airplane. This would give you tremendous pain and there'd be nothing you could do about it. Chance worth taking? ...Read more

See your doctor.: Kidney stones hurt and you should have pain medication to get you through them. Doctors usually get imaging on the stones to find out their size.

I first had a kidney stone when I was 14 then recently at 19. Both times I didn't pass them and I believe it was both kidneys. What could happen?

Pass or stuck: Your kidney stone will pass eventually, but that depend on the size and location.
If it is inside the kidney, a piece might brake off and try to pass with the urine.
If it is sitting in the lip of the kidney, then if it is too large it might cause some king of obstruction which is painful, and could be dangerous.
You need to see a urologist to check about the status of your kidney function. ...Read more

I have 6mm kidney stone in my kidney and am in pain dr say u shouldn't b in pain. It's in ur kidney is it possible that it could b stone?

Obstruction = Pain: Kidney stones that are within the kidney and not causing any obstruction to the flow of urine are generally not symptomatic. If a stone blocks the flow of urine, pressure builds up above the stone causing stretching (hydronephrosis) and deep pain. That said, sometimes a stone can be obstructing a single calyx (see image) and can cause pain, even though the stone is not within the ureter. ...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

How fast can't kidney stones grow? It's for a school assignment and I'm having trouble finding information.

How fast can't kidney stones grow? It's for a school assignment and I'm having trouble finding information.

Here's your answer: The vast majority of kidney stones certainly grow very slowly, as we commonly see them as incidental findings at autopsy and they have surely been growing for many years. This being said, a proteus infection in the kidney or a hyperuricemic crisis during an illness can precipitate struvite or uric acid solids in the kidney which could easily form a stone in short order. ...Read more

Have a friend who was diagnosed with kidney stone 8 days ago and still hasn’t passed it. How/when should he go back to the doc?

Have a friend who was diagnosed with kidney stone 8 days ago and still hasn’t passed it. How/when should he go back to the doc?

Kidney stone.: Kidney stones up to 5mm in size will predictably pass on their own. Your friend should drink plenty of water to produce a lot of urine, dilate those ureters and allow the stone to pass. It may hurt while it's on its way out, but it'll pass. Bigger stones will likely get stuck and will cause tremendous pain and will have to be removed by lithotripsy or cystoscopy. ...Read more

However, even if not seen, you can still have blood called microscopic, which is detected by checking the urine. If you have fever, the problem could be more serious as infection may be present. ...Read more
