Consider diseases caused by stones in the urinary tract, including kidney stones or ureteral stones. When stones occur in the urinary tract, there can be pain in the lower back and corresponding abdominal pain, which is very severe in nature and accompanied by digestive symptoms, that is, nausea and vomiting, which is usually the contents of the stomach and does not contain bile or blood. As the stone moves down the ureter, it can damage the ureteral mucosa, resulting in blood in the urine. An abdominal ultrasound is usually sufficient to make a definitive diagnosis, as ultrasound is particularly sensitive to the presence of stones. After the diagnosis is clear, lithotripsy, including extracorporeal lithotripsy or ureteroscopic lithotripsy, is needed. At the same time, when the pain is obvious, we need to give painkillers to treat the symptoms.
