The bladder growths are not necessarily tumors, but also other lesions may be present, specifically in the following areas: 1, glandular and cystic cystitis, which is a type of chronic and proliferative cystitis, mainly due to long-term chronic stimulation of the urinary tract, such as stones and long-term indwelling catheters, which can easily lead to this disease, causing focal elevation of the mucosal surface of the bladder, which can be multifocal and can also form polypoid or papillary hyperplasia. 2. nephrogenic adenoma, also known as nephrogenic metaplasia, is a specific type of metaplastic epithelial metaplasia and not a true tumor, occurring mostly after chronic inflammatory stimulation, radiation therapy or surgery. 3. papillary and polypoid cystitis, in which the mucosa is focally or multifocally elevated, is a verrucous proliferative lesion. 4. inflammatory pseudotumor of the bladder, a specific chronic inflammatory condition that is primarily a verrucous proliferation, also known as myofibroblastoma. Mainly the bladder wall will out realistic masses. So the bladder grows something not necessarily a tumor, but also inflammatory or verrucous proliferative lesions, it is recommended that patients must seek medical attention to clarify the disease so that targeted treatment can be provided.
