Second, your doctors will decide how to treat your stone. In some people, doctors will also order an intravenous pyelogram or lVP, a special type of X- ray of the urinary system that is taken after injecting a dye. The KUB test may be used to monitor your stone before and after treatment, but the CT scan is usually preferred for diagnosis. The KUB x-ray is often obtained by the surgeons to determine if the stone is suitable for shock wave treatment. This can be done with a high resolution CT scan from the kidneys down to the bladder or an x-ray called a "KUB x-ray'' (kidney-ureter-bladder x-ray) which will show the size of the stone and its position. Your doctors will want to know the exact size and shape of the kidney stones. This is what causes the pain.ĭiagnosis of a kidney stone starts with a medical history, physical examination, and imaging tests.
But stones that don't move may cause a back-up of urine in the kidney, ureter, the bladder, or the urethra. Sometimes, tiny stones move out of the body in the urine without causing too much pain. The stone-forming chemicals are calcium, oxalate, urate, cystine, xanthine, and phosphate.Īfter it is formed, the stone may stay in the kidney or travel down the urinary tract into the ureter. In most people, having enough liquid washes them out or other chemicals in urine stop a stone from forming. Usually, these chemicals are eliminated in the urine by the body's master chemist: the kidney. The crystals attract other elements and join together to form a solid that will get larger unless it is passed out of the body with the urine. When there is too much waste in too little liquid, crystals begin to form. Urine has various wastes dissolved in it. Common symptoms include severe pain in lower back, blood in your urine, nausea, vomiting, fever and chills, or urine that smells bad or looks cloudy. A kidney stone may be treated with shockwave lithotripsy, uteroscopy, percutaneous nephrolithomy or nephrolithotripsy. There are four types of kidney stones: calcium oxalate, uric acid, struvite, and cystine. A kidney stone is a hard object that is made from chemicals in the urine.
