The hematuria will clear up in a few days, depending on what disease is causing the hematuria. If the hematuria is caused by inflammation, it will usually get better in 3-5 days. If the hematuria is caused by a stone, the stone has not moved and drinking more water will relieve it in 1-2 days, and the stone will move again and cause hematuria. If the hematuria is caused by urinary tract tuberculosis, it lasts longer. If the hematuria is caused by trauma, the hematuria will only be relieved if the condition is effectively controlled and the bleeding stops, which usually lasts 1-2 weeks. If the hematuria is caused by a tumor in the urinary tract, it may occur intermittently, and the hematuria will be completely relieved only after the tumor is removed. It is important to drink more water when hematuria occurs, and the cause of the hematuria must be found.
