What size kidney stone requires ureteroscopy?
Ureteroscopy with laser lithotripsy (URS) may be used for stones up to 2 centimeters in size located anywhere in the ureter or kidney. This procedure involves passing a small diameter fiberoptic ureteroscope through the bladder and into the ureter, allowing the surgeon to see the stone.

The smaller the kidney stone, the more likely it will pass on its own. If it is smaller than 5 mm (1/5 inch), there is a 90% chance it will pass without further intervention. If the stone is between 5 mm and 10 mm, the odds are 50%. If a stone is too large to pass on its own, several treatment options are available.
Most often ureteroscopy is used for stones in the ureter, especially for stones closest to the bladder, in the lower half of the ureter. lt is the most common treatment of lower ureteral stones. For stones in the kidney, shock wave lithotripsy (SWL) is the most common treatment.
Stones that are smaller than 2 cm in diameter are the best size for SWL. The treatment might not be effective in very large ones. SWL is more appropriate for some people than others. Because x-rays and shock waves are needed in SWL, pregnant women with stones are not treated this way.
Typically, any stone 4 millimeters (mm) or less in length will pass on its own within 31 days. Between 4 mm and 6 mm, only 60 percent will pass without medical intervention, and on average take 45 days to exit your body naturally. Anything bigger than 6 mm will almost always need medical care to help remove the stone.
Very small stones (up to 3mm) can even pass without any pain as they may not cause any blockage on their way out. Stones between 3 and 5 mm often cause pain (renal colic) while passing down the ureter. Small stones in the kidney generally continue to grow over months or years.
If a kidney stone becomes lodged in the ureters, it may block the flow of urine and cause the kidney to swell and the ureter to spasm, which can be very painful. At that point, you may experience these symptoms: Severe, sharp pain in the side and back, below the ribs. Pain that radiates to the lower abdomen and groin.
If you have stones, you may experience sharp pain that occurs intermittently as the kidney spasms while attempting to eliminate the stone from your body. This pain may feel similar to a back muscle strain. Expect to experience spasms around 1 to 4 times per hour until the stone passes into your ureter.
Even small stones can cause extreme pain as they exit your body through your urinary tract. Drinking fluids may help the process, which can take as long as three weeks. A large kidney stone can get trapped in your ureter (the tube that drains urine from your kidney down to your bladder).
How many days rest required after ureteroscopy?
You will need to rest for 24 hours. You should have someone stay with you during that time. Your surgeon will likely prescribe medicines for you to take at home. This may include a pain medicine and an antibiotic to prevent infection.
SURGICAL OPTIONS — The most commonly used surgical procedures for stone removal are minimally invasive techniques such as shock wave lithotripsy (SWL), ureteroscopy (URS), and percutaneous nephrolithotomy (PNL). Other, less commonly performed, procedures include laparoscopic, robot-assisted, and open surgery.
Most patients are able to perform normal, daily activities within 5-7 days after ureteroscopy.
In the case of kidney stones, they can help widen the tube that connects the kidney with the bladder (ureter). This gives a larger stone more room to pass. Evidence suggests that alpha-1 blockers like Flomax may be most effective for kidney stones larger than 5 mm.

Staying hydrated can help pass kidney stones faster. Certain substances, including apple cider vinegar and lemon juice, may help dissolve kidney stones, making them easier to pass. Drinking plenty of fluids can help pass kidney stones and prevent new stones from forming.
This may be surprising, but it's not fast at all. A kidney stone typically forms slowly over the course of months or even years. It's usually at least a few months before the person with the kidney stone experiences pain or other symptoms.
Those that are 5 to 7 mm (larger than a pencil erasure but smaller than a green pea) can be passed in 50 percent of cases. Stones that are larger than 7 mm rarely pass without a surgical procedure. There is usually no permanent damage if kidney stones are recognized and treated in a timely fashion.
Sometimes, a kidney stone does not cause any symptoms and is only found when imaging tests are done for another reason. Stones can remain in the kidneys for years without ever causing symptoms. However, stones typically do cause symptoms when they pass from the kidneys through the urinary tract.
According to the American Urological Association, the length of time required to pass a kidney stone located in the ureters (tube that connects kidneys to the bladder), is an average of 8 days if the stone is less than 2mm, about 12 days for a stone between 2mm and 4mm, and 22 days if the stone is between 4mm and 6mm.
How fast can a kidney stone move through the ureter?
Small kidney stones are considered 1-5 millimeters (mm) taking on average 8 to 12 days to pass. Smaller stones are most likely the fastest to pass and exit through the urine. Large kidney stones are considered greater than 5 mm, taking on average 22 days or longer to pass.
Proximal ureteral stones are also less likely to pass spontaneously. On the initial CT-KUB scan, our patient's stone was in the proximal left ureter. Paradoxically, after that, the stone had migrated spontaneously upward to the renal calyx. This phenomenon has been reported only once in the literature.
You may not notice if you have small kidney stones. You'll usually pee them out without any discomfort. Larger kidney stones can cause several symptoms, including: pain in the side of your tummy (abdomen)
pain in the side of your tummy (abdomen) or groin – men may have pain in their testicl*s. a high temperature. feeling sweaty. severe pain that comes and goes.
Often, the pain worsens at night, disrupting sleep. The correct sleeping position can alleviate the pain and help the stones pass quickly, but the best position to lay with kidney stones varies from person to person.
