polypoid cystitis


Also found in: Dictionary, Thesaurus, Encyclopedia.

polypoid cystitis

A reactive inflammatory lesion of the urinary bladder characterised by cytologically unremarkable urothelium of normal thickness, which is thrown into broad undulations overlying a markedly oedematous lamina propria.

cystitis

inflammation of the urinary bladder. The condition may result from an ascending infection coming from the exterior of the body by way of the urethra, or it may be caused by an infection descending from the kidney. Often cystitis is not an isolated infection but is rather a result of some other physical condition. For example, urinary retention, calculi in the bladder, tumors, or neurological diseases impairing the normal function of the bladder may lead to cystitis.
Clinical signs include freqency, pain on urination, blood-stained urine, a thickened bladder wall. Significant clinical pathology findings include hematuria, a high cell count indicative of inflammation, and a positive bacterial culture.
