Bladder stones are hard mineral deposits that form in the bladder when urine becomes concentrated. They can develop when the bladder does not empty completely, leading to the crystallization of minerals. Symptoms may include pain during urination, frequent urination, and blood in the urine. Treatment for bladder stones often involves increasing fluid intake to help flush them out. In some cases, medical procedures may be necessary to break up or remove larger stones. Preventive measures include staying hydrated and addressing any underlying conditions that may contribute to stone formation, such as urinary tract infections or enlarged prostate.
