Kidney or bladder stones are solid accumulations of crystals made from minerals and proteins found in urine. Bladder diverticulum enlarged prostate, neurogenic bladder and urinary tract infection can cause an individual to have a greater chance of developing bladder stones. If a kidney stone becomes lodged in the ureter or urethra, it can cause constant severe pain in the back or side, vomiting, haematuria (blood in the urine) fever or chills.
Bladder stones are hard masses of minerals in your bladder. Bladder stones develop when urine in your bladder becomes concentrated, causing minerals in your urine to crystallize. Concentrated, stagnant urine is often the result of not being able to completely empty your bladder. If bladder stones are small enough, they can pass on their own with no noticeable symptoms. However, once they become larger, bladder stones can cause frequent urges to urinate, painful or difficult urination and haematuria.
Kidney stones (nephrolithiasis): Minerals in urine form crystals (stones), which may grow large enough to block urine flow. It's considered one of the most painful conditions. Most kidney stones pass on their own but some are too large and need to be treated.
