Incidence, severity, and risk factors for hemorrhagic cystitis (HC) were assessed in 267 patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). HC was diagnosed in 14.6% (39 patients) within 1-139 days after allo-HSCT (median duration – 39 days). Chemotherapy-related HC was diagnosed in 4 patients only. The majority (1935) of patients developed late HC of viral aetiology. Median time from a day of HC diagnosis to clinical symptoms resolution was 25 days (range: 6 to 133 days). Using a multivariate analysis, allo-HSCT from mismatched unrelated/haploidentical donor was found to be a risk factor of HC (р=0.01). The analysis also showed that 82.1% of patients with HC received cyclophosphamide as a part of conditioning regimen or +3/+4 days after allo-HSCT.
