Encrusted cystitis: aetiology, clinical aspects and management.

Encrusted cystitis is a rare condition characterised by the formation of calcified plaques adherent to or embedded in the bladder mucosa. Although chronic infection with urea-splitting organisms is a prerequisite, other factors seem to play an important role in its development. We report our experience of 4 such cases in which encrusted cystitis presented with various symptoms, produced different pathological abnormalities and was treated by different means in each patient.
