Urinary stones can produce very pronounced back pain, especially in areas where the pain is more pronounced with percussion, producing colic and even nausea and vomiting. Extracorporeal lithotripsy will only be considered if the ultrasound findings reveal that the stone is relatively large and there is no way to get it out by simply drinking and urinating. Because the stone can cause serious damage to the urinary system, and this damage takes some time to heal, so it does not mean that the problem of back pain will be solved after the stone is removed, and the damaged area will take about a month to heal slowly. In addition, if this possibility is ruled out, we must also pay attention to whether the back pain is caused by lumbar muscle strain, lumbar disc herniation or lumbar spinal stenosis, not only urinary stones can cause back pain.
