Kidney stones – Diagnosis and treatment – Mayo Clinic

Diagnosis

If your doctor of the church suspects that you have a kidney stone, you may have diagnostic tests and procedures, such as :

  • Imaging. Imaging tests may show kidney stones in your urinary tract. High-speed or dual department of energy computerized imaging ( CT ) may reveal evening bantam stones. simple abdominal X-rays are used less frequently because this kind of imaging test can miss modest kidney stones .
    Ultrasound, a noninvasive test that is promptly and easy to perform, is another imaging choice to diagnose kidney stones.

  • Analysis of passed stones. You may be asked to urinate through a strainer to catch stones that you pass. Lab analysis will reveal the makeup of your kidney stones. Your doctor uses this information to determine what’s causing your kidney stones and to form a plan to prevent more kidney stones.

Treatment

treatment for kidney stones varies, depending on the type of rock and the lawsuit .

Small stones with minimal symptoms

Most minor kidney stones wo n’t require invasive discussion. You may be able to pass a little rock by :

  • Drinking water. Drinking as much as 2 to 3 quarts (1.8 to 3.6 liters) a day will keep your urine dilute and may prevent stones from forming. Unless your doctor tells you otherwise, drink enough fluid — ideally mostly water — to produce clear or nearly clear urine.
  • Pain relievers. Passing a small stone can cause some discomfort. To relieve mild pain, your doctor may recommend pain relievers such as ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve).
  • Medical therapy. Your doctor may give you a medication to help pass your kidney stone. This type of medication, known as an alpha blocker, relaxes the muscles in your ureter, helping you pass the kidney stone more quickly and with less pain. Examples of alpha blockers include tamsulosin (Flomax) and the drug combination dutasteride and tamsulosin (Jalyn).

Large stones and those that cause symptoms

Parathyroid glands

Parathyroid glands

Parathyroid glands

The parathyroid gland glands lie behind the thyroid. They produce parathyroid gland hormone, which plays a role in regulating the soundbox ‘s blood degree of calcium and phosphorus .
Kidney stones that are besides large to pass on their own or cause shed blood, kidney price or ongoing urinary tract infections may require more-extensive treatment. Procedures may include :

  • Using sound waves to break up stones. For certain kidney stones — depending on size and localization — your doctor of the church may recommend a procedure called extracorporeal daze wave lithotripsy ( ESWL ) .
    ESWL uses sound waves to create strong vibrations ( shock waves ) that break the stones into bantam pieces that can be passed in your urine. The operation lasts approximately 45 to 60 minutes and can cause moderate pain, so you may be under sedation or light anesthesia to make you comfortable .
    ESWL can cause blood in the urine, bruising on the back or abdomen, bleeding around the kidney and early adjacent organs, and discomfort as the gem fragments pass through the urinary nerve pathway .
  • Surgery to remove very large stones in the kidney. A routine called transdermal nephrolithotomy ( nef-row-lih-THOT-uh-me ) involves surgically removing a kidney gem using small telescopes and instruments inserted through a modest incision in your back .
    You will receive general anesthesia during the surgery and be in the hospital for one to two days while you recover. Your sophisticate may recommend this operating room if ESWL is abortive .

    once the pit is located, special tools can snare the stone or break it into pieces that will pass in your urine. Your doctor may then place a little tube ( stent ) in the ureter to relieve well and promote bring around. You may need general or local anesthesia during this procedure .
  • Parathyroid gland surgery. Some calcium phosphate stones are caused by hyperactive parathyroid gland glands, which are located on the four corners of your thyroid gland gland, merely below your Adam ‘s apple. When these glands produce excessively much parathyroid gland hormone ( hyperparathyroidism ), your calcium levels can become excessively high and kidney stones may form as a leave .
    hyperparathyroidism sometimes occurs when a small, benign tumor forms in one of your parathyroid gland glands or you develop another condition that leads these glands to produce more parathyroid gland hormone. Removing the growth from the gland stops the geological formation of kidney stones. Or your doctor of the church may recommend treatment of the condition that ‘s causing your parathyroid gland gland to overproduce the hormone .

Prevention

    If you live in a hot, dry climate or you exercise frequently, you may need to drink even more water to produce adequate urine. If your urine is idle and clear, you ‘re probably drink enough water .
