Definition
=========================================================================

● Clinical syndrome of gross hematuria, often with irritative bladder symptoms

Etiology
=========================================================================

● Due to drug treatment (cyclophosphamide, methotrexate, ifosphamide), radiation therapy (eMedicine), viral infection (adenovirus, herpes simplex virus, CMV, BK virus)
● Post allogeneic hematopoietic stem cell transplantation (Chin Med J (Engl) 2008;121:1766)
● Occurs in 10% of pediatric bone marrow transplants (J Pediatr Urol 2009;5:254)

Clinical
=========================================================================

● Irritative voiding symptoms, gross hematuria

Case reports
=========================================================================

● 8 year old with BK-virus associated hemorrhagic cystitis presenting as mural nodules (Pediatr Radiol 2010;40:1430)
● 49 year old man with symptoms after receiving penicillin for endocarditis (Intern Med 2009;48:1667)
● 70 year old man with hemorrhagic cystitis due to melphalan (Case Report Med 2010;2010:569138)

Treatment
=========================================================================

● Clot evacuation and hydration, bladder irrigation with saline or alkalinized saline, intravesical instillation of aluminium hydroxide/magnesium hydroxide
