What is "glomerulation"

n. (context pathology English) The occurrence of many tiny hemorrhages on the wall of the bladder

Glomerulation refers to bladder hemorrhages which are thought to be associated with some types of interstitial cystitis (IC).

The presence of glomerulations, also known as petechial hemorrhages, in the bladder suggests that the bladder wall has been damaged, irritated and/or inflamed. In fact, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Diagnostic Criteria for IC, developed in 1987, required the presence of glomerulations or Hunner's Ulcers to make a firm diagnosis of IC and is still used, today, to determine patient eligibility for some clinical trials. Research conducted by Waxman, however, determined that the hydrodistention procedure itself may have created these tiny broken blood vessels. Thus, a diagnosis of IC is now based upon other, less invasive methods, such as the PUF questionnaire.
