Urosepsis is one of major cause of the overall sepsis leading to high morbidity and mortality, which commonly resulted from urinary tract calculi. The investigator aim to identified the incidence and risk factors of urosepsis in the patients with urinary tract calculi underwent surgical intervention in tertiary-care university hospital.

Sepsis is one of the leading cause of death of hospitalized patients in Thailand. Urosepsis or sepsis which originate from urinary tract infection was reported around 9-31% of the overall sepsis syndrome. Urinary tract calculi requiring surgical procedure was reported as a common cause of urinary tract infection. Therefore, the investigators aimed to identified the incidence and risk factors of urosepsis in the patients with urinary tract calculi underwent surgical intervention in tertiary-care university hospital.

Moreover, the patients with sepsis syndrome will be suffered from many complications such as acute respiratory distress syndrome, acute kidney injury, etc. Currently, there were many early waring scores to predict the risk of complications to help promptly treatment and decrease the severity. The investigator would like to compare the systemic inflammatory response syndrome (SIRS) criteria,Modified Early Warning Score (MEWS) and Quick Sequential Organ Failure Assessment (qSOFA) score to the prediction of postoperative complications in this group of patients.

The last primary objective of this study is to follow the course of the patients diagnosed as urosepsis if they had been treated properly according to the sepsis bundle guideline and their outcome.
