[Analysis of patients with septic shock due to urosepsis brought on by ureteral calculi].

While a ureteral stone is a common disease, it occasionally causes urosepsis and septic shock. We analyzed 6 cases of septic shock due to urosepsis caused by a ureteral stone from August 1998 to September 2001. All patients were female, ranging in age from 38-76 years old (63.8 +/- 15.3). Stones ranged from 4 to 12 ml in size. The results of analysis of bacterial culture from blood and urine revealed E. coli in 4 cases, K. pneumoniae in 1 case and P. mirabilis in 1 case. Treatment, including intravenous transfusion, the administration of vasopressor drugs and antibiotics, and anti-disseminated intravascular coagulation (DIC) treatments were performed. Percutaneous nephrostomy in 4 cases and ureteral stent indwelling in 1 case were also used for the management of urinary tract. Extracorporeal shock wave lithotripsy (ESWL) was performed in 4 patients after improvement of general condition. Furthermore, the 3 most recent patients had also received therapy to remove endotoxins. All patients were diagnosed in a stone-free condition after a combination of these therapies. The mean recovery interval from shock condition to shock-free status seemed to be shorter in the patients that received the endotoxin removal therapy.
