Patients with cystitis do not need to undergo cystoscopy. The main examinations for patients with cystitis include routine urine tests, bacteriological examination of urine, routine blood tests, kidney function tests, ultrasonography of the urinary system, and X-rays including abdominal plain films. Diagnostically, it mainly depends on the patient's clinical manifestations and a comprehensive judgment based on the results of these auxiliary examinations. Patients with cystitis generally experience symptoms such as frequent urination, urgency, painful urination, and discomfort or pain in the lower abdomen and perineal area.
