High dose cyclophosphamide and/or busulfan conditioning treatment of recipients of bone marrow transplants proved to be highly effective but associated with substantial and sometimes life threatening hemorrhagic cystitis. To prevent this complication, a prophylactic continuous bladder irrigation program was instituted in patients receiving cyclophosphamide and/or busulfan in preparation for bone marrow transplantation. Retrospective analysis of 199 patients who underwent allogeneic bone marrow transplantation revealed that continuous bladder irrigation significantly decreased the frequency of hemorrhagic cystitis in patients receiving busulfan and cyclophosphamide (continuous bladder irrigation 23% versus no bladder irrigation 53%, p < 0.004). There was no difference in the frequency of hemorrhagic cystitis between the different preparative regimens in patients who underwent continuous bladder irrigation. There was no relationship between the incidence of hemorrhagic cystitis and the severity of graft-versus-host disease or the time to engraftment. The duration of hemorrhagic cystitis and overall survival rates were similar in both groups, and there was no increase in complications related to catheterization. In general, continuous bladder irrigation was well tolerated, decreased the incidence of hemorrhagic cystitis and may be useful in bone marrow transplant patients.
