How is the severity of adenocystitis differentiated? The severity of adenocystitis can be differentiated based on its microscopic appearance and pathologic changes. Under cystoscopy, you can observe the size, distribution, location, etc. of adenoid cystitis. If the adenoid cystitis is distributed in masses, which means that there are more layers, and if it is closer to the ureteral opening, these are more serious manifestations. Pathologically, if adenoid cystitis is found to have increased nuclear anisotropy, it is also a sign of severity. Adenoid cystitis is a type of precancerous bladder cancer and requires active treatment.
