Bladder stones are stones formed inside the bladder, including both primary and secondary bladder stones. The typical symptoms of bladder stones are pain and hematuria, often accompanied by interrupted urine flow, which is a distinctive manifestation of bladder stones. Through ultrasound examination of the urinary system, the size, shape, and number of stones inside the bladder can be detected. For the treatment of bladder stones, small stones can typically pass through the urethra on their own, generally if they are less than 0.6 centimeters. Larger bladder stones can be treated with intravesical lithotripsy. Methods of lithotripsy include extracorporeal shock wave lithotripsy and transurethral lithotripsy to break and remove the stones. Additionally, individuals with bladder stones should drink plenty of water, urinate frequently, and avoid spicy and irritating foods.
