[Relevance of clinical and serum parameters on severe urinary sepsis after renal obstruction.]

Abstract:

INTRODUCTION:Urosepsis is an underdiagnosed entity with high morbidity and mortality and significant associated costs. The delay in diagnosis leads to an increased risk of multiorgan failure and death. Although its prognosis is better than that of other sepsis, the mortality rate is 20 - 40%. OBJECTIVE:Describe the obstructive uropathy cases (OU) that are complicated by severe sepsis (SS) and identify early biomarkers of SS. MATERIAL AND METHODS:Observational and prospective study of 65 patients with urgent high OU. All patients were evaluated at three different times (0, 24 and 48 hours). An SS predictor model has been constructed and a multivariate risk analysis has been carried out. RESULTS:64.61% (n=42) developed SS (NSS: n=13). The only statistically significant variables in the 3 moments evaluated and that obtained a good area under the curve [AUROC (>0.70)] were the elevation of neutrophils, procalcitonin, and decrease of bicarbonate. At the time of patient admission, the variable that best predicted SS was the elevation of procalcitonin (AUROC:0.919). SS risk factors (p<0.005) were the history of cancer immunosuppression, and/or urinary tract surgeries, complete UO and high blood values of lactate, potassium and decrease of bicarbonate. The potassium-lactate combination on admission predicted SS with a probability function of 0.805. CONCLUSIONS:There is an analytical profile maintained over the time characteristic of SS that allows anearly identification of patients with OU subsidiary of been complicated with SS. :INTRODUCCIÓN: La Sepsis urinaria obstructiva (SUO) es una entidad infradiagnosticada con una elevada morbimortalidad e importantes costes asociados. El retraso en su diagnóstico condiciona un mayor riesgo de fracaso multiorgánico y fallecimiento. Aunque su pronóstico es mejor que el de otros focos de sepsis, su mortalidad es del 20 - 40%. OBJETIVO:Describir los cuadros de uropatía obstructiva (UO) que se complican con sepsis grave (SG) e identificarlos biomarcadores diagnósticos de SG en la UOde forma precoz.MATERIAL Y MÉTODOS: Estudio observacional y prospectivo de 72 pacientes con UO alta ingresados de manera urgente en el Servicio de Urología del Hospital Clínico Universitario de Valladolid. Todos los pacientes del estudio fueron evaluados en tres momentos diferentes (0, 24 y 48 horas). Se ha creado un modelo predictor de SG y se ha realizado un análisis multivariante de riesgo. RESULTADOS:El 64,61% de los pacientes (n=42) desarrolló SG (NSG: n=13). Las únicas variables estadísticamente significativas en los tres momentos evaluados y que obtenían una buena área bajo la curva [AUROC (>0,70)] fueron la elevación de neutrófilos y procalcitonina y la disminución de bicarbonato. En el momento del ingreso la variable que mejor predecía SG fue la elevación de procalcitonina (AUROC: 0,919). Los factores de riesgo de SG (p<0,05) fueron los antecedentes de cáncer, la inmunosupresión y/o cirugías de vías urinarias, la UO completa y los valores elevados en sangre de lactato y potasio y la disminución del bicarbonato en la gasometría venosa. La combinación potasio-lactato al ingreso predecía SG con una función de probabilidad de 0,805. CONCLUSIONES:Existe un perfil analítico, mantenido en el tiempo, característico de SG que permite la identificación precoz de los pacientes con UO subsidiarios de complicarse con SG.
