Kidney stones are hard stones that can cause severe pain on the side of your abdomen/waist, along with blood in your urine and nausea or vomiting. You are more likely to develop kidney stones if you eat a particular diet, do not drink enough fluids or if you are overweight. Once you have had one episode, they are likely to recur, but there are several treatment options available. Most stones are made of calcium, or can be of uric acid or a mix of both.
Abdominal pain, pain in kidney, renal colic, blood in urine or urine infection are the most common symptoms. You are more likely to form a stone if your urine is concentrated. Majority of the stones that cause renal colic are small and pass out themselves with the urine in a day or so. Some stones become stuck in a kidney or in one of the tubes (the ureters), which drains the urine from the kidney and can cause persistent symptoms or problems. In these cases, the pain usually becomes severe and you may need to visit a hospital and take treatment, after proper diagnosis.
