[Successful therapy of uncontrollable macrohematuria caused by the cyclophosphamide-injured bladder]. / Erfolgreiche Therapie unstillbarer Makrohämaturie bei Cyclophosphamid-Blase.

An uncontrollable bleeding of the urinary bladder was successfully treated using a 4% formalin strip tamponade with vesico-ureteral reflux and supportive therapy with thrombocyte concentrates and transfusions of fresh blood. Non-toxic side-effects of oxazaphosphorin derivates and modern methods of prophylaxis using a uroprotectic are presented. Previously the use of formalin together with vesicoureteral reflux was contraindicated; in this case it was successfully applied for the first time via the suprapubic route using a strip tamponade.
