Controlled Clinical Trial
Continuous bladder irrigation prevents hemorrhagic cystitis after allogeneic hematopoietic cell transplantation.
Hemorrhagic cystitis is 1 of the most troublesome complications of hematopoietic cell transplantation conditioning regimens. We conducted a nonrandomized controlled clinical study to investigate the role of continuous bladder irrigation in addition to mesna, hydration, and alkalization in the prevention of hemorrhagic cystitis after allogeneic hematopoietic cell transplantation. A total of 80 eligible patients entered the study. ⋯ High-grade hemorrhagic cystitis was more frequently associated with high-grade graft-versus-host disease within 30 days after transplant (P = 0.06). In general, continuous bladder irrigation added to mesna, hydration, and alkalization regimens was well tolerated, decreased the complications of hemorrhagic cystitis, and may be useful in hematopoietic cell transplantation patients. However, more investigations with randomized controlled clinical trials with more patients are needed.
