What does bladder space occupying lesion mean?

The bladder is an important part of the body that stores urine. Once a disease occurs, it will inevitably have a great impact on the urinary system. There are many diseases related to the bladder in life, so what does bladder space occupying mean?

What does bladder occupying mean?

"Space-occupying lesions" is a special term in medical imaging diagnosis, usually appearing in the results of X-ray, B-ultrasound, CT, MRI (magnetic resonance imaging), DSA (digital subtraction angiography), etc. It means: there is an "extra object" in the examined part. This "extra object" can cause the surrounding tissues to be compressed and displaced. Space-occupying lesions usually refer to tumors (benign or malignant), parasites, stones, hematomas, etc., without involving the cause of the disease.

“Space-occupying lesions” ≠ cancer

Space-occupying lesions are not equal to cancer. In clinical work, experienced doctors can generally make a clear diagnosis based on the patient's medical history. This term is only used when it is difficult to determine. At this time, the doctor will ask the patient to provide a more detailed medical history, refer to other examinations, or do some special CT scans to further clarify.

“Space-occupying lesions” can be either benign or malignant

Space-occupying lesions can be divided into malignant space-occupying lesions and benign space-occupying lesions according to their nature. Malignant space-occupying lesions mainly include cancer, sarcoma, etc., among which cancer is the most common. Sarcoma is a malignant tumor originating from vascular endothelial cells. It is relatively rare, but generally does not metastasize everywhere, and the survival period is longer than cancer. Benign space-occupying lesions can be roughly divided into two types: cystic space-occupying and solid space-occupying. Cystic space-occupying lesions mainly include cysts, abscesses, etc., among which cysts are more common; solid space-occupying lesions mainly include hemangiomas, cellular adenomas, focal nodular hyperplasia, focal fatty liver, inflammatory pseudotumors, tumor-like hyperplasia, etc., among which hemangiomas are the most common. After the discovery of space-occupying lesions, the first thing to do is to make a qualitative diagnosis, that is, to determine the nature of the patient's space-occupying lesions, whether they are benign or malignant. Various imaging examinations can not only cooperate with qualitative diagnosis, but also perform localization diagnosis, that is, to further determine the location, size, number of space-occupying lesions and their relationship with surrounding tissues. The most commonly used localization diagnosis is CT, magnetic resonance imaging, and B-ultrasound. When necessary, arterial angiography can be used to provide a basis for whether surgical treatment is appropriate.
