Sent to Health Experts September 23 05:04 PM

My son who is 18 years old, was just diagnosed with multiple kidney stones in the kidney. He was admitted in the hospital for urinating blood, thats how we found out what he had. My concern is he has so many stones to pass. How long can the stones remain there before it can cause damage to the kidney? You should know that he also has a horseshoe kidney. His uric acid level in his blood was a 12.2 and it was 1,700 in his urine. I know thats extremely high, especially for someone his age. Also, his endocronologist doesn't think its necessary to see a kidney specialist but I should see a urologist. His kidneys, they say are funtioning fine now. Please give me your input.

Reply to Dr AMIT MUNJAL's Post: On the cat scan they said they saw 2 stones. One was 2cm and one was 3cm. The Sonogram is the one that showed a clearer picture of the kidney. That showed multiple stones in kidney. I asked how many and the size of them, and they didn't know because there was so many. It also showed sand residue from the stones. He has a strainer to urinate in and only passed very few orange sandy I think stones. The endoronologist wants me to take one that is big enough to the lab to analize it. They did not say anything about Hydronephrosis. I'm worried about how long they should remain there before they could damage the kidney. He is taking allopurinol and Colchicine.

Hello

Stones less than 5 mm in size usually will pass spontaneously, however the majority of stones greater than 6 mm will require some form of intervention, especially so if the stone is stuck causing persistent obstruction and/or infection of the urinary tract. But since you are telling size in cm ,i dont think it will pass spontaneously.This needs some intervention . Horseshoe kidneys often sit in front of the great blood vessels in the abdomen. This plus its unusual blood supply make it a risk when performing surgery involving the abdominal aorta .ESWL (Extra corporeal shock wave lithotripsy) is considered the first therapeutic option for cases of lithiasis with a mean area 4 cm2 or less and pelvic location. In case of great lithiasic areas other therapeutic options should be considered (open surgery or percutaneous nephrolithotomy) either in monotherapy or complementary to ESWL.You can have a look on success rate of this procedure in the following link.

Regarding the damage caused to kidney by stones i would say this depends on this factor

1) Degree of Hydronephrosis- Hydronephrosis is distention (dilation) of the kidney with urine, caused by backward pressure on the kidney when the flow of urine is obstructed.Prolonged hydronephrosis results in the eventual loss of kidney function .

Reply to Dr AMIT MUNJAL's Post: Thank you for your reply. That helped me but I also need to know how long can these stones remain in the kidney before causing harm to it. He got back from the hospital Friday afternoon and only passed these sand like stones which were orange in color. There are only about 2 or 3. The doctor said I should wait until he passes one bigger. Now, all day Saturday and today, he hasn't passed any. How dangerous is this, if he continues not to pass them. Thank you again.

Hello

If the stone is causing obstruction and causing the kidneys to swell (moderate to severe hydronephrosis) than this is dangerous. If stone is not causing much obstruction than it can remain in kidney for two to three months without causing much damage. Also if the stone has sharp and pointed it can cause damage due to its shape.

So the extent of damage depends on size and shape of stone and associated obstruction.If a stone is causing obstruction then it can cause associated kidney infections to complicate the matter further.

Hope this helps.

I asked this question yesterday at 7:18 pm and usually I would get a response the morning after, so I'll just ask again.

My son is on Allopurinol. How long should this take to start to break up the kidney stones in his kidney?

Hello

If hypercalciuria is present, then allopurinol will not prevent calcium stones from forming. Also if the size of stone is in 2- 3 cm i dont think allopurinol will be efficacious in dissolving it all together.Allopurinol is more prophylactic in preventing formation of new stones rather than curative.
