How long can a kidney stone be stuck in my ureter before any damage is done?

How long can a kidney stone be stuck in my ureter before any damage is done?

Difficult to say: In studies on dogs in the past, if a kidney was completely blocked, there was some irreversible damage that stated to occur at 2 weeks. If the obstruction is not 100%, you probably have longer before seeing any permanent effects on 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 an urinalysis and an exam to make sure 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

I was told I had a 3mm kidney stone in the top of my left ureter two days ago and that I should be able to pass it without a lot of problems. I have?

Kidney stone: Drink plenty of liquids and strain all your urine through something like a handkerchief. The stone will look very tiny. If you retrieve it, it will be analyzed by the laboratory to see what kind of stone it is. If you don't retrieve a stone and have no symptoms, you may have passed it or it may still be present. Notify your urologist who may send you for another imaging test. ...Read more

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

My husband is having two kidney stones in the right kidney. One is 8mm and the other is 6mm. The 6mm stone is in the end of the ureter & 8mm on the top.

My husband is having two kidney stones in the right kidney. One is 8mm and the other is 6mm. The 6mm stone is in the end of the ureter & 8mm on the top.

Location location: Kidney stones could be "obstructing" or "non obstructing". Beyond treating these stones, your husband needs to take preventive steps to prevent further stones from forming. This includes water intake. A nephrologist (kidney specialist) should be able to order special urine studies to determine the cause of stone formation and prescribe customized treatment. ...Read more

2nd time kidney stones w/in 10mos. 1x: 3mm-stuck in l distal ureter & 6mm-l kidney. 2x: 5mm & 2mm-l kidney & 5mm-r kidney. Do I get lithotripsy again?

2nd time kidney stones w/in 10mos. 1x: 3mm-stuck in l distal ureter & 6mm-l kidney. 2x: 5mm & 2mm-l kidney & 5mm-r kidney. Do I get lithotripsy again?

Possibly: Lithotripsy's results depend on the size and location of the stones along the urinary tract. However, equally importantly, you need to be investigated to figure out why you are having recurrent stones, and take appropriate measures like increased water intake (and, possibly other medications) that should reduce your risk of future stones. ...Read more

I am suffering from kidney stone which is now in distal ureter. Can I eat carrot or drink carrot juice?

Sure: Nothing in carrot juice is relevant to kidney stone treatment. Drinking lots of water (which the kidney then eliminates) may help push the stone down the ureter. If you are a "stone-former" I suggest you get an evaluation by a nephrologist to determine possible preventive strategies. ...Read more

5 mm. kidney stone that has been sitting at the top of the ureter for 9 days. Urologist recommends Lithotripsy. Reasonable or useless to tough it out?

5 mm. kidney stone that has been sitting at the top of the ureter for 9 days. Urologist recommends Lithotripsy.  Reasonable or useless to tough it out?

Should pass without : Need for intervention. Also, depends upon symptoms. You have had multiple stones in past & presumably passed most or all. Worth active intervention to remove ureteroscopically or have stent placed if UR in pain. This is very small stone & certainly too small for extra-corporal shock wave lithotripsy (ESWL). Hope you have had metabolic work-up for stones! ...Read more

Can I tell if kidney stone has transited from ureter to bladder by change in symptoms?CT scan shows a 4mm stone 1.5 CM from bladder.

Can I tell if kidney stone has transited from ureter to bladder by change in symptoms?CT scan shows a 4mm stone 1.5 CM from bladder.

See answer: The only true accurate means of determining whether an ureteral calculus has passed is to retrieve it by straining your urine. The chance of spontaneous passage of a 4mm stone ~50-60%. Onset of symptoms of urinary urgency, frequency, burning, voiding small volumes usually indicates the stone is at the UVJ (ureter meets bladder). The absence or disappearance of pain does not guarantee stone passage. ...Read more
