The significance of joint evaluation of gastrointestinal ultrasound results and renal artery resistance index for assessing intestinal-renal syndrome in sepsis patients: a retrospective study.

ABSTRACT:

Background

Sepsis triggered by intra-abdominal infections (IAI) carries significant morbidity and mortality. The gut and kidneys are critically vulnerable in sepsis, with crosstalk potentially driving "intestinal-renal syndrome"-worsening gut dysfunction leading to acute kidney injury (AKI) and vice versa. Doppler ultrasound offers non-invasive hemodynamic assessment: the superior mesenteric artery resistance index (SMARI) reflects splanchnic perfusion, whereas the renal artery resistance index (RRI) indicates renal vascular resistance. However, the combined role of serial SMARI and RRI measurements in tracking intestinal-renal syndrome progression and predicting outcomes in IAI-induced sepsis remains inadequately explored. This study aimed to visually judge the process of enterore
