Abstract
Encrusted cystitis (EC) and encrusted pyelitis (EP) are rare chronic inflammatory diseases of the bladder and renal pelvis, respectively, and are characterized by mucosal inflammation with deposits of ammonium magnesium phosphate on the urothelium. Corynebacterium urealyticum is the pathogen responsible in the vast majority of cases. We report 4 cases of EC and 1 case of EP. In 1 case of EC Ureaplasma urealyticum was isolated as the microorganism responsible. To the best of our knowledge, U. urealyticum–induced EC has never been reported previously.
