Bladder occupations mainly manifest as soft tissue lesions in the bladder, which need to be combined with various examinations to further determine the benign or malignant nature, mainly including clinical examination, imaging examination, cystoscopy and pathologic biopsy.
1. Clinical examination: most of the symptoms of benign bladder occupations are not obvious, and some of them may be accompanied by bladder irritation; malignant bladder occupations may present with hematuria and a decline in physical condition.
2. Imaging examination: benign bladder occupations have smooth margins, not rich in blood supply, and the bladder wall is structurally intact; malignant bladder occupations often have uneven margins, rich blood supply, and some of them have liquefaction necrosis, and the neighboring bladder wall is invaded.
3. Cystoscopy: benign bladder occupations have smooth surface by cystoscopy, and most of them are not accompanied by ulceration; malignant bladder occupations have irregular edges by cystoscopy, and some of them are accompanied by erosion, ulceration and hemorrhage.
4. Pathological biopsy: the pathological biopsy of benign occupancy of bladder belongs to abnormal proliferation of cells, which is not accompanied by disordered proliferation; malignant occupancy of bladder can be found malignant tumor cells, with obvious cellular heterogeneity.
Pathological biopsy is the gold standard for diagnosing the benign or malignant nature of a specific lesion, and bladder occupancy should be treated in a standardized manner under the guidance of a clinician.
