title: Haemorrhagic cystitis as a complication after allogenic bone marrow transplantation.
abstract: OBJECTIVE
  The main objective of the following work is to present our own material and the ways in which we have dealt with haemorrhagic cystitis (HC) following allogenic bone marrow transplantation in children.
  
  
  METHODS
  From 1994 to 2002, allogenic transplantation of haematopoietic cells was performed in 129 children at the Oncological and Haematological Child Clinic, Wroclaw University of Medicine. The procedure was carried out in patients with neoplastic diseases. In 33 cases, HC symptoms of various intensity were observed. The intensity of the symptoms was evaluated according to Arthur's four-point scale. To confirm the diagnosis USG was carried out in each case. Special attention was given to the ultrasonographic structure of the bladder wall. Cartoni's technique was followed in the examination.
  
  
  RESULTS
  Out of 129 children who underwent allogenic transplantation of haematopoietic cells 33 (20.75 %) revealed HC symptoms. The symptoms occurred between the 2nd and the 124th day after transplantation (mean 29 days). The treatment included antiviral medicines, estrogens, reduction of immunosuppression and mechanical urological procedures. The children diagnosed with 2nd grade disease and higher were catheterised and diuresis was forced by the administration of larger amounts of liquids intravenously. Antihaemorrhagic drugs and vitamin K were also given. Blood was substituted if needed as were blood derivatives. Eighteen children with massive haematuria with clots underwent catherisation with a suprapubic catheter so as to continuously rinse the bladder. In 8 cases tamponade of the bladder occurred. The clots were removed from the bladder during cystoscopy under general anaesthesia. Twelve children died from HC. This amounts to 36 % of all the cases identified as HC and 9 % of all the children who underwent allogenic marrow transplantation.
  
  
  CONCLUSIONS
  In conclusion it must be emphasised that HC in children after allogenic transplantation of haematopoietic cells is an extremely severe disease, which, if not cured, is terminal. The decision whether to perform embolisation of internal iliac arteries or to remove the bladder when non-radical methods have been exhausted, is worth considering.
