Patients with cystitis may experience hematuria, commonly terminal hematuria, which occurs towards the end of urination. Sometimes, blood is present throughout the entire urination process, even with blood clots being expelled. The onset is often quite sudden, and may be accompanied by frequent urination, urgency, and painful urination, with severe cases needing to urinate every few minutes, regardless of day or night. Therefore, when cystitis leads to hematuria, there is no need for concern. Timely treatment can fully resolve the issue, and it is important not to be overly stressed mentally.
