How does cyclophosphamide cause hemorrhagic cystitis?
Cyclophosphamide causes hemorrhagic cystitis by renal excretion of its hepatic metabolite, acrolein, which is urotoxic.
How can cyclophosphamide prevent hemorrhagic cystitis?
During cyclophosphamide treatment, plenty of oral fluids, bladder irrigation and frequent voiding are recommended since-these reduce the time of contact of acrolein with the bladder mucosa, thereby minimising the chances of cystitis.

What are the side effects of cyclophosphamide for cystitis?
A known adverse effect of such treatment is hemorrhagic cystitis. A series of 100 patients with hemorrhagic cystitis induced by cyclophosphamide was studied. Major symptoms were gross hematuria (78%) and irritative voiding symptoms (45%). Microhematuria developed in 93% of patients.
