Kidney or bladder stones are the crystals of calcium oxalate and uric acid. If a kidney stone obstructs the urethra or the ureter, it results in haematuria (blood in the urine), constant and severe pain in the back or side, fever, vomiting, or chills. Nephrolithiasis (Kidney stones): Minerals in urine form stones, which may generate into a size big enough to block the flow of urine. Most kidney stones pass through urine on their own, but some kidney stones are too large and they cannot pass hence should be treated.

Bladder stones are hard masses of minerals in the urinary bladder. Bladder stones create when urine in the bladder becomes more concentrated, resulting in the minerals to take up shapes. Concentrated, stagnant urine is the regular after-effect of not having the capacity to totally exhaust the bladder. On the off chance that bladder stones are sufficiently small, they can go all alone with no detectable indications. In any case, once they get bigger, bladder stones can bring about incessant inclinations to urinate, excruciating or troublesome urination and haematuria.
