title: [Clinical study on 6 cases of urosepsis associated with septic shock].
abstract: At Asama General Hospital, we experienced six cases of urosepsis with septic shock during a period of five years between 1989 and 1993. All six patients, whose average age was 74 years old, recovered. In four patients, the condition was caused by obstructive uropathy. The remaining two cases were caused by renal inflammatory disease, which was complicated by diabetes mellitus. One of them was renal abscess with renal papillary necrosis, and the other was emphysematous pyelonephritis. The patients, who exhibited symptoms such as gram-negative bacteremia, severe hypotension, tachycardia, decrease of urine volume and mental disturbance, were diagnosed with urosepsis with septic shock. In all cases, symptoms such as a high fever of over 39 degrees C, hypoxemia and thrombocytopenia were observed. Renal dysfunction was found in 67%, and both liver dysfunction and disseminated intravascular coagulation (DIC) were found in 50% of the cases. Since no patients suffered from adult respiratory distress syndrome, a high survival rate was apparent. Anti-shock therapy and anti-coagulation therapy were ineffective for the patients who had septic shock due to urinary tract obstruction. Urinary tract drainage was required to treat the latter patients. Nephrectomy could not be avoided in renal parenchymatous inflammatory disease. In the future, what might be essential in therapeutics against urosepsis with septic shock, particularly to avoid nephrectomy, are the treatments such as immunotherapy against endotoxins and their mediators, and hemoperfusion for the removal of endotoxins.
