Treatment Of Urinary Tract Stones
Nonsteroidal anti-inflammatory drugs or opioids as needed to relieve pain
Sometimes stone removal
Small stones that are not causing symptoms, blockage of the urinary tract, or an infection usually do not need to be treated and often pass on their own. Larger stones and those that are closer to the kidney are less likely to pass on their own. Some drugs may increase the likelihood of spontaneous stone passage.
Diagnosis Of Urinary Tract Stones
Doctors usually suspect stones in people with renal colic. Sometimes doctors suspect stones in people with tenderness over the back and groin or pain in the genital area without an obvious cause. Finding blood in the urine supports the diagnosis, but not all stones cause blood in the urine. Occasionally, the symptoms and physical examination findings are so distinctive that no additional tests are needed, particularly in people who have had urinary tract stones before. However, most people are in so much pain and have symptoms and findings that make other causes for the pain seem likely enough that testing is necessary to exclude these other causes. Doctors need to differentiate stones from other possible causes of severe abdominal pain, including
Helical CT done without the use of radiopaque contrast material is usually the best diagnostic procedure. CT can locate a stone and also indicate the degree to which the stone is blocking the urinary tract. CT can also detect many other disorders that can cause pain similar to the pain caused by stones. The main disadvantage of CT is that it exposes people to radiation. Still, this risk seems prudent when possible causes include another serious disorder that would be diagnosed by CT, such as an aortic aneurysm or appendicitis. Newer CT devices and methods that limit exposure to radiation are now commonly used.

Lower Pole Caliceal Stones
SWL is the initial treatment of choice for most of the small-to moderate-sized renal calculi, but its use for lower pole caliceal stones is controversial. The reported clearance rate of SWL for LPCS is 25-85%. The stone clearance decreases with increase in stone size. In a meta-analysis, Lingeman et al. found SFR of 74% for stones > 1 cm and 56% for 1-2 cm stones after SWL. Kupeli et al. reported an overall SFR of 53% with SWL for inferior caliceal stone, 62% for sones of > 1 cm, and 48% for 1-2 cm stones. May and Chandhoke reported SFR of 75% for stones > 2 cm after SWL.
Sampaio and Aragao and Elbahnasy et al. suggested that caliceal anatomy is an important factor to predict the success of SWL for LPCSs, but other authors reported no significance for either radiographic anatomy or stone bulk. Srivastava et al. evaluated the effect of these two factors prospectively for LPCSs of > 2 cm as the predictor for successful stone clearance. At three months, 78.8% renal units were clear of stones. On intravariable analysis, various anatomical parameters like infundibulopelvic angle, infundibular diameter, and length were significant, but on multivariate analysis, stone size was the most significant predictor of stone clearance.

Who Is Likely To Develop A Kidney Stone
The rate of people who develop kidney stones is increasing in the U.S. The reasons for the trend are unknown. The prevalence of kidney stones was 3.8% in the late 1970s. In the late 1980s and early 1990s, the number rose to 5.2%. Caucasian ethnicity and male gender are associated with higher rates of kidney stones. Men tend to develop kidney stones in their 40s through 70s rates increase with age. Women are most likely to experience kidney stones in their 50s. A person who has suffered from one kidney stone is more likely to develop others.

What Is The Treatment For Kidney Stones
Most people with kidney stones are able to pass them on their own within 48 hours by drinking plenty of fluids. Pain medication can ease the discomfort. The smaller the stone, the more likely it is to pass without intervention. Other factors that influence the ability to pass a stone include pregnancy, prostate size, and patient size. Stones that are 9 mm or larger usually do not pass on their own and require intervention. Stones that are 5 mm in size have a 20% chance of passing on their own while 80% of stones that are 4 mm in size have a chance of passing without treatment.
Measuring The Kidney Stone Size
To successfully pass a kidney stone through your system, it is essential to have a gauge of size to know if exterior intervention is necessary.
Typically, any stone 4 millimeters 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. If passed without care of a urologist, the severe pain can last upwards of a year.

How Can Kidney Stones Be Prevented
The best way to avoid kidney stones is to prevent the most common cause â dehydration. You are adequately hydrated when your urine is light yellow. Most people require between 8 to 10 glasses of water per day. Scientists are studying grapefruit juice and other drinks high in citric acid, which may help prevent the most common type of kidney stone.
When Treatment For Uvj Stones Is Urgent
If a patient has signs and symptoms of infection, this must addressed urgently with placement of ureteral JJ stent to relieve obstruction. Antibiotics are given to treat the infection before the stone can be broken. A double-J stent is urgently placed between the bladder and the kidney in the ureter while the infection and obstructing stone are present.
Similarly if patient has acute renal failure or insufficiency , urgent treatment is advised. Typically a ureteral stent called double J stent or JJ-stent is placed.
An ureteral stent is a plastic tube that is inserted into the ureter to keep it open and prevent urine from backing up into the kidney. A stent also needs to be inserted if the ureter is too narrow for surgical instruments to pass through. In such cases, a stent is left in place for a few weeks to allow the ureter to dilate passively.

Some Kidney Stones Can Be Passed On Their Own
Small kidney stones can pass without intervention. Those that are as small as a grain of sand likely wont cause pain as they pass out of the body, while larger stones can become stuck in the ureter, the tube that passes urine from the kidney to the bladder.
Sometimes these types of small stones will pass within a few days, explains Ralph V. Clayman, MD,professor in the department of urology at the University of California in Irvine. Others take longer, though if they are going to pass on their own, most will do so within two to three weeks.
Pain can be severe at first and may require narcotics for relief, says Dr. Clayman. But as the stone moves through the urinary tract, pain can often be managed using nonsteroidal anti-inflammatory medication, he says. Drinking water can help to pass the stone.
With guidance and supervision of your doctor oftentimes people can stay at home while passing a kidney stone on their own.
What Are The Types Of Kidney Stones
The four types of kidney stones are:
Calcium oxalate stones are the most common type of kidney stone. They represent almost 70-80% of all stones. They are caused by a build-up of calcium and oxalate or phosphate. While there are many reasons for why calcium stones form, calcium intake, too little fluid intake, or even too much Vitamin C consumption are some of the more well recognized causes.
This type of kidney stone can be caused by urine that is too acidic or in individuals with gout. It results from the buildup of uric acid.
Struvite kidney stones are uncommon . They are typically caused by certain bacteria that may infect the kidney. Stones are comprised of magnesium, phosphate and ammonium.
Cystine stones are quite rare and usually only found in people with genetic condition called cystinuria. This condition makes them unable to reabsorb a normal body chemical, called cystine. As a result, they excrete an abnormal amount of cystine which can crystallize, forming stones.

How Are Kidney Stones Treated
Once diagnosed, your healthcare provider will first determine if you even need treatment. Some smaller kidney stones may leave your system when you urinate. This can be very painful. If your provider decides that you do need treatment, your options include medications and surgery.
Medications. Medications may be prescribed to:
- Your healthcare provider may recommend that you take an over-the-counter medication like ibuprofen or, if youre in the emergency room, an IV narcotic.
- Manage nausea/vomiting.
- Relax your ureter so that the stones pass. Commonly prescribed medicines include tamsulosin and nifedipine .
You should ask your healthcare provider before you take ibuprofen. This drug can increase the risk of kidney failure if taken while youre having an acute attack of kidney stones especially in those who have a history of kidney disease and associated illnesses such as diabetes, hypertension and obesity.
Surgery. There are four types of surgeries used to treat kidney stones. The first three are minimally invasive, meaning that the surgeon enters your body through a natural opening , or makes a small incision.
What Does It Feel Like To Have A Kidney Stone
Everyone experiences kidney stones differently. Typically, kidney stones within the kidney do not cause pain.
If a stone falls onto the opening where the kidney meets the ureter or passes into the ureter, this can prevent urine from draining out of the kidney. This backing up of urine can lead to back pain just below your ribs. Sometimes the pain can be severe enough to cause nausea and vomiting.
As a stone moves, the blockage of urine may be relieved and symptoms may improve or go away. The pain may return if the stone begins to cause blockage of urine again. This changing of symptoms is called renal colic.
Blood in the urine may be a sign of kidney stones. Sometimes the blood isnt visible to the naked eye and must be detected by a urine test.
If a stone is able to pass down the ureter and close to the bladder, the pain may move to the front of the abdomen, near the pelvis.
Stones very close to the bladder can cause pain that is felt in the genitals. A stone that reaches the bladder can cause burning with urination or changes in how often or how urgently you need to urinate.

Whats The Outlook For Kidney Stones
The outlook for kidney stones is very positive, although there is a risk of recurrence . Many kidney stones pass on their own over time without needing treatment. Medications and surgical treatments to remove larger kidney stones are generally very successful and involve little recovery time.
Its possible to get kidney stones multiple times throughout your life. If you keep developing kidney stones, your healthcare provider may work with you to discover why the stones happen. Once the cause is found, you may be able to make dietary changes to prevent future stones.

Causes Of Urinary Tract Stones
Stones may form because the urine becomes too saturated with salts that can form stones or because the urine lacks the normal inhibitors of stone formation. Citrate is such an inhibitor because it normally binds with calcium that is often involved in forming stones.
Stones are more common among people with certain disorders and among people whose diet is very high in animal-source protein or vitamin C or who do not consume enough water or calcium. People who have a family history of stone formation are more likely to have calcium stones and to have them more often. People who have undergone surgery for weight loss may also be at increased risk of stone formation.
Rarely, drugs and substances in the diet cause stones.
What Is The Treatment For Stones That Do Not Pass On Their Own
Lithotripsy is a procedure that uses shock waves to break a kidney stone into smaller pieces that can be more easily expelled from the body. The device used for this procedure is called a Lithotripter. Kidney stones can also be removed surgically. A percutaneous nephrolithotomy is a procedure in which a kidney stone is removed via a small incision in the skin. A kidney stone may also be removed with a ureteroscope, an instrument that is advanced up through the urethra and bladder to the ureter.

Keeping Kidney Stone Pain Under Control
If you are experiencing the intense discomfort of kidney stones , pain control is a top priority. A 2018 analysis of multiple randomized trials looked at different pain relief medicines given to people treated in the emergency department for acute renal colic. It compared nonsteroidal anti-inflammatory drugs with paracetamol or opioids. The study found NSAIDs offered effective pain relief with fewer side effects than paracetamol or opioids. NSAIDs directly inhibit the synthesis of prostaglandins, which decreases activation of pain receptors and reduces renal blood flow and ureteral contractions.
Kidney Stone Treatment Options
We work with patients in every stage of their condition, creating a personalized plan whether surgery is needed or not. We also try to identify factors that may be causing the stones, so we can keep current stones from getting larger and reduce the risk of developing future stones.
When suspected of having a kidney stone, we take a history, perform a physical, exam, and obtain radiological imaging. Studies may include a plain x-ray of the abdomen, a renal ultrasound, or a CT scan. They help us determine the location of the stone, its size, the degree to which the stone may be causing an obstruction to urine flow, and what types of therapy would be appropriate for management.

Preventing Future Kidney Stones
If you had a calcium stone, your doctor may suggest cutting back on salt, which cause the body to dispense more calcium into the urine, as well as animal protein. You may also be advised to avoid high-oxalate foods, including chocolate, instant coffee, tea, beans, berries, dark leafy greens, oranges, tofu, and sweet potatoes. The best way to ward off new kidney stones is to drink enough water to keep urine clear.
