Cystone is used to treat and prevent kidney and urinary tract stones, treat urinary tract infections, treat kidney pain, and treat burning urination. Cystone treats excess salts in the urine and prevents infection from bacteria in the urinary tract. It is used before and after urinary surgeries. Kidney and urinary tract stones can cause severe pain to the patient, especially when moving, but they usually do not cause permanent damage if they are detected in time and treated.
