Kidney Stone Signs And Symptoms

What causes kidney stones? – Arash Shadman

Kidney stones are conglomerations of crystals that form when concentrations of minerals in the urine become very high. As their name implies, stones almost always start in the kidneys. They may cause problems there, or may not be noticed until they move into the ureter . Once stones enter into the ureter the can obstruct the drainage of urine which generally causes symptoms such as pain in the upper back or lower abdomen, nausea, vomiting, and blood in the urine. Many stones will pass down the ureter, into the bladder and then be voided with urine. Occasionally stones can remain lodged in the ureter or within the bladder.

Blocked Ureter And Kidney Infection

A kidney stone that blocks the ureter can lead to a kidney infection. This is because waste products are unable to pass the blockage, which may cause a build-up of bacteria.

The symptoms of a kidney infection are similar to symptoms of kidney stones, but may also include:

  • a high temperature of 38C or over
  • chills and shivering

Kidney stones are usually formed following a build-up of certain chemicals in the body.

This build-up may be any of the following:

  • calcium
  • ammonia
  • uric acid a waste product produced when the body breaks down food to use as energy
  • cysteine an amino acid that helps to build protein

Certain medical conditions can lead to an unusually high level of these substances in your urine.

Youâre also more likely to develop kidney stones if you donât drink enough fluids.

Panel Selection And Peer Review Process

The Surgical Management of Stones Panel was created in 2013 by the American Urological Association Education and Research, Inc. . The Practice Guidelines Committee of the AUA selected the Panel Chair who in turn appointed the additional panel members with specific expertise in this area. The Endourological Society also nominated two representatives to serve on the panel. Once nominated, all panel members were asked to record their conflict of interest statements, providing specific details on the AUA interactive web site. These details are first reviewed by the Guidelines Oversight Committee , a member sub-committee from the PGC consisting of the Vice Chair of the PGC and two other members. The GOC determines whether the individual has potential conflicts related to the guideline. If there are conflicts, then the nomineeâs COI is reviewed and approved by the AUA Judicial and Ethics committee. A majority of panel members may not have relationships relevant to the Guideline topic.

What Size Of Kidney Stones Require Surgery

The hard deposits of minerals such as calcium or uric acid that form in the kidneys are called kidney stones. It is one of the most common health conditions that trouble both genders.

Some kidney stones that are quite small in size, tend to pass on their own through urine. That is why drinking enough water and healthy fluids helps a lot in dealing with kidney stones.

Whether a stone can pass naturally through the urine or needs medical intervention for removal depends upon the size, type, and location of the stone. In most cases, stones that have a high probability of getting stuck anywhere in the urinary tract require surgical treatment for removal.

According to doctors, the kidney stones that are larger than 6mm in size can obstruct the ureter or bladder. This causes intense pain and complications. These stones have less than a 20 percent chance of passing naturally and even if they do, it may take up to a year for this to happen. Thus, doctors are of the opinion that the kidney stones of 6mm or more require surgery.

A quick fact: Stones of size 4mm or less have an 80 percent chance of passing on their own. The probability of a stone passing through urine decreases with the increase in the size of the stone.

Other reasons for carrying out surgery for kidney stones may include intense and unbearable pain, an infection in the kidney stone, or the obstruction of urine flow by the kidney stone.

Keeping Kidney Stone Pain Under Control

If you are experiencing the intense discomfort of kidney stones , pain control is a top priority.

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 Stones Are More Common In Summer And In Hotter Climates

Theres a reason summer is called kidney stone season.

Hot weather leads to dehydration, which causes more kidney stones in warmer climates, Nabhani says. The southeastern United States is known as the Stone Belt, because the incidence of kidney stones is higher in this warm region. Drink your water, especially if its hot!

If you regularly sweat a lot during exercise, such as with hot yoga, be sure to stay hydrated as well.

Prevention Of Future Stones

What size kidney stone will pass on its own?

Once your health care provider finds out why you are forming stones, he or she will give you tips on how to prevent them. This may include changing your diet and taking certain medications. There is no “one-size-fits-all” diet for preventing kidney stones. Everyone is different. Your diet may not be causing your stones to form. But there are dietary changes that you can make to stop stones from continuing to form.

Diet Changes

Drink enough fluids each day.

If you are not producing enough urine, your health care provider will recommend you drink at least 3 liters of liquid each day. This equals about 3 quarts . This is a great way to lower your risk of forming new stones. Remember to drink more to replace fluids lost when you sweat from exercise or in hot weather. All fluids count toward your fluid intake. But it’s best to drink mostly no-calorie or low-calorie drinks. This may mean limiting sugar-sweetened or alcoholic drinks.

Knowing how much you drink during the day can help you understand how much you need to drink to produce 2.5 liters of urine. Use a household measuring cup to measure how much liquid you drink for a day or two. Drink from bottles or cans with the fluid ounces listed on the label. Keep a log, and add up the ounces at the end of the day or 24-hour period. Use this total to be sure you are reaching your daily target urine amount of at least 85 ounces of urine daily.

Reduce the amount of salt in your diet.
Eat the recommended amount of calcium.

The Donts You Need To Remember

  • Avoid eating junk, foods with added sugar, and preservatives. Such food items make the kidney stones grow severe and aggravate the pain.
  • You just cannot and must not lead a sedentary mode of lifestyle. This increases the risk of obesity. With obesity comes numerous health problems including pesky kidney stones.
  • You gotta cut down on caffeine and carbonated colas. These drinks are not nourishing and rather impart dehydrating effects. And, you are already aware of the negative connection of kidney stones and dehydration.
  • Last but not the least, cigarettes and alcohol. Nothing harms your body than these two ill habits. And the harm does not limit to your physical health. Prolonged smoking and excessive alcohol consumption only trigger intense pain of kidney stones along with other complications.
