据统计,55％以上的革兰氏阴性杆菌败血症起源于泌尿生殖道,其中25％为特发性,75％属医源性。梗阻性或非梗阻性尿路病变均可引起急性或亚急性尿路败血症。其中上尿路梗阻所致的败血症极易发生败血性休克(约占59～78％),休克使败血症的死亡率增高2～4倍。非梗阻性尿路败血症往往属医源性,为 According to statistics, more than 55% of Gram-negative bacilli sepsis originated in genitourinary tract, of which 25% are idiopathic and 75% are iatrogenic. Obstructive or non-obstructive urinary tract disease can cause acute or subacute urinary tract sepsis. Septicemia caused by upper urinary tract obstruction septic shock prone to septic shock (about 59 to 78%), shock increased sepsis mortality by 2 to 4 times. Non-obstructive urinary sepsis is often iatrogenic, for
