There is no authoritative data to show the ratio of benign and malignant. The bladder occupation may be caused by localized stones, bladder inflammation or tumor growth, which need to be judged specifically. 1. Bladder stones: bladder stones are not malignant in nature, they are localized deposits caused by long-term lack of water or metabolic and circulatory disorders, and may cause local pain, hematuria, or difficulty in defecation, etc. Surgery is recommended for treatment. 2. Cystitis: Inflammation of the bladder may also appear as bladder occupying lesion on imaging, which is benign, and can be effectively treated by taking anti-inflammatory drugs as prescribed by the doctor, such as levofloxacin, etc. It is necessary to pay attention to the side-effects and adverse reactions of the drugs, and please use the above medicines under the guidance of the doctor. 3. Bladder tumor: bladder tumor is a more common cause of bladder space-occupying lesions. The incidence of malignant bladder tumors is higher, but there are also benign tumors. In the presence of tumor-occupying lesions, pathology should be examined in a timely manner, and surgical or antitumor therapy should be chosen according to its malignancy and specific growth rate. In the presence of bladder occupying lesions can be combined with imaging, ultrasound or tissue sections to determine the nature of the specific lesion, so as to treat as early as possible.
