[Experience of direct hemoperfusion using polymyxin B-immobilized fiber on patients with endotoxin shock from urosepsis].

We report the effects of direct hemoperfusion using polymyxin B-immobilized fiber (PMX treatment) on two patients with endotoxin shock from urosepsis. In both cases, urosepsis caused by pyelonephritis from a ureteral stone progressed to endotoxin shock and disseminating intravascular coagulation (DIC). Single J catheter was indwelt in the ureter for the purpose of drainage before PMX treatment. Drainage of the origin of infection, using effective antibiotics and PMX treatment improved shock state and DIC earlier than we expected.
