Kidney or bladder stones are solid build-ups 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, hematuria (blood in the urine), fever, or chills.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 hematuria.
