Blood in urine is a more prominent symptom of kidney stones, which mostly occurs after renal colic. The management of blood in urine depends on the color, nature, and severity of the hematuria. The cause of blood in urine from kidney stones is mainly due to the rough surface of the stone rubbing in the renal pelvis, causing bleeding from ruptured capillaries in the mucosa of the renal pelvis or the ureteral mucosa. The clinical term for blood in urine is called carnal hematuria. A light red color, or a mild type of hematuria like a wash of flesh water, suggests more than 1 ml of blood per liter of urine, which can usually be relieved by drinking more water. In this case, we should drink more water to keep the daily urine volume at 2000-3000ml, and more urination can effectively dilute the color of urine; if the hematuria is blood-like or dark red and sticky with a large number of blood clots, it is relatively serious, and the patient should go to the urology department of a regular hospital and take appropriate hemostatic drugs under the guidance of the doctor to control the symptoms of hematuria. At the same time, kidney stone hematuria needs to be treated with antibiotics to prevent infection. After finding blood in urine, patients should further check the stone situation by doing ultrasound, taking pictures, doing CT, etc. to clarify the size of stones, the location of stones and the number of stones. This is because only by expelling the stones can the hematuria be effectively relieved. For smooth stones less than 6mm, if there is no obstruction in the urinary tract below the stone and the stone has not caused complete obstruction, stone removal flush can be taken, together with more water and proper exercise, which will help to expel the stone. If the stone is larger than 6mm, treatment such as extracorporeal shock wave lithotripsy, or ureteroscopic surgery, or percutaneous nephrolithotomy to remove the stone can be considered.
