Some people need to be catheterized after cystoscopic electrodesiccation, and the catheter needs to be removed 2 days after the operation, the specific situation is closely related to the scope of the operation and the postoperative recovery, and needs to be standardized under the guidance of the clinician. Cystoscopic electrodesection is mainly for tumor lesions in the bladder, which need to be catheterized for bladder perfusion treatment and irrigation after the operation. If the lesion is relatively light and the operation scope is shallow, the postoperative recovery is good, and the catheter can be removed in 2 days in most cases; if the operation scope is large and the postoperative bleeding is persistent, the recovery time will be prolonged, and the time for removing the catheter will be prolonged as well. Persistent bleeding after cystoscopic electrodesiccation, accompanied by abdominal pain, requires timely medical observation and standardized treatment under the guidance of the clinician, which should not be neglected to avoid delay or aggravation of the condition.
