Abstract: Determinar si injuria renal aguda es predictor de estancia hospitalaria prolongada en pacientes postoperados de cirugía abdominal. Material y métodos: Se analizó una cohorte retrospectiva de 144 pacientes postoperados de cirugía abdominal de los cuales 48 presentaron injuria renal aguda y 96 no lo presentaron y se determinó su riesgo relativo de presentar estancia hospitalaria prolongada. Resultados: Estancia hospitalaria prolongada presentaron 20 (41,7%) pacientes con injuria renal aguda y 10 (10,4%) pacientes sin injuria renal aguda (p<0,001). El riesgo relativo de estancia hospitalaria prolongada por injuria renal aguda fue 4,00 (IC 95%: 2.04-7,86). En el análisis bivariado los factores asociados a estancia hospitalaria prolongada fueron: género masculino (p=0,002), hipertensión arterial (p=0,009) y tiempo operatorio ≥ 60 minutos (p<0,001). En el análisis multivariado los factores asociados a estancia hospitalaria prolongada fueron: injuria renal aguda (p=0,011, RR: 3,9 IC 95% 1,362-11,20), género masculino (p=0.007, RR: 4.086 IC 95% 1,480-11,279) y tiempo operatorio ≥ 60 minutos (p=0,007, RR 17,561, IC 95% 2,177-141,687). Conclusión: La injuria renal aguda es un factor predictor de estancia hospitalaria prolongada en pacientes postoperados de cirugía abdominal.

To determine if acute kidney injury is a predictor of prolonged hospital stay in post-abdominal surgery patients. Material and methods: A retrospective cohort of 144 postoperative abdominal surgery patients was analyzed, of whom 48 presented acute kidney injury and 96 did not present it, and their relative risk of presenting prolonged hospital stay was determined. Results: Prolonged hospital stay was presented by 20 (41.7%) patients with acute kidney injury and 10 (10.4%) patients without acute kidney injury (p<0.001). The relative risk of prolonged hospital stay for acute kidney injury was 4.00 (95% CI: 2.04-7.86). In the bivariate analysis, the factors associated with prolonged hospital stay were male gender (p=0.002), arterial hypertension (p=0.009) and operating time ≥60 minutes (p<0.001). In the multivariate analysis, the factors associated with prolonged hospital stay were acute kidney injury (p=0.011, RR: 3.9 95% CI 1.362-11.20), male gender (p=0.007, RR: 4.086 95% CI 1.480 -11.279) and operating time ≥ 60 minutes (p=0.007, RR 17.561, 95% CI 2.177-141.687). Conclusion: Acute kidney injury is a predictor of prolonged hospital stay in post-abdominal surgery patients.
