If you have back pain when urinating, you should pay attention to the possibility of urinary tract stones and ask if you have hematuria, urinary frequency and urinary urgency. By testing routine urine, ultrasound examination of kidney, ureter and bladder, effective diagnosis and differential diagnosis can be made, and if there are stones ultrasound can detect. If there are red cells and white cells in the urine, it may be a urinary tract infection. It is recommended that if there are small stones, drinking more water and urinating more often can provide relief. If the stone is larger, larger than 0.5cm, it is recommended to use extracorporeal shock wave lithotripsy to break up the stone and expel it from the body. If there is also a combination of inflammation, you should increase the oral antibacterial agent, commonly used antibacterial agent recommended levofloxacin, and drink more than 1500ml of water per day.
