Patients with cystitis may experience symptoms of lower abdominal distention and discomfort, as well as frequent urination, urgent urination, and painful urination. Patients presenting these symptoms should first visit the urology department of a hospital to undergo routine urine analysis and urinary system ultrasound to confirm the diagnosis of cystitis. Once diagnosed, under the guidance of a consulting physician, treatment involves oral or intravenous antibiotics. Additionally, patients are advised to drink plenty of water and urinate frequently, which can assist in the treatment of cystitis.
