Hemorrhagic cystitis (HC) presenting with gross hematuria, bladder pain and urinary frequency develops in 13-38% of patients following bone marrow transplantation (BMT). The objective of the study was to study the characteristics of patients suffering hemorrhagic cystitis after hematopoietic stem cell transplantation in our center. We conducted a retrospective chart review of all patients who underwent BMT at our institution between January 1996 and August 2012. We recorded the age, sex, diagnosis, conditioning regimen, interval between BMT and development of symptoms of cystitis and treatment instituted. Five hundred patients underwent BMT in the period of time studied. 52 of them developed hemorrhagic cystitis. The mean age of the affected patients was 39 years; there were 34 males and 18 females. The diagnoses include AML (n=11), ALL (n=8), CML (n=6), MDS (n=11), CLL (n=5), NHL (n=1), HD (n=5), MM (n=2), Medular aplasia((n=3). HC appeared 59.48 days after BMT. There were no differences between sexes. Mortality among the 52 patients was 51.14% but HC was not the cause of death in any patient. Polyomaviruses were detected in the urine of 78.94 % of survivors. Polyomavirus infection with BK and JC types is usually acquired in infancy and the virus remains latent in renal tissue. Immunosuppression facilitates reactivation of the renal infection and replication of the virus responsible for the clinical manifestations of HC. The differential diagnoses include other urinary infections, lithiasis, thrombocytopenia and adverse effects of pharmacological agents. The urologist plays a limited role in the management of this disease.
