Fully developed cyclophosphamide-induced cystitis is characterized by nearly complete detachment of the urothelium, severe submucosal edema owing to damage to the microvascular bed and focal muscle necroses. The initial response to the primary attack by the cyclophosphamide metabolites seems to be fragmentation of the luminal membrane. This damages the cellular barrier against the hypertonic urine. Subsequent breaks in the lateral cell membranes of the superficial cells and in all the plasma membranes of the intermediate and basal cells, intercellular and intracellular edema and disintegration of the desmosomes and hemidesmosomes lead to progressive degeneration and detachment of the epithelial cells with exposure and splitting of the basal membrane. The morphological changes of the endothelial cells, which become more pronounced in the later stages of the experiment, the involvement of blood vessels regardless of their diameter and the location-dependent extent of the damage indicate a direct type of damage which is preceded by a mediator-induced increase in permeability, the morphological correlate of which is the formation of gaps in the interendothelial cell connections on the venules. These changes can be effectively prevented by mesna. The only sign of a possible involvement is the increase in the number of specific granules with a presumed lysosomal function in the superficial cells.
