ABSTRACT
INTRODUCCIÓN: El uso de un esquema antibiótico inadecuado en sepsis aumenta significativamente la morbimortalidad. Este estudio presenta un reporte multicéntrico de susceptibilidad antibiótica en urosepsis asociada a ureterolitiasis, buscando proponer un esquema empírico óptimo para el medio nacional. MÉTODOS: Se realizó un estudio observacional prospectivo en 7 hospitales de 4 regiones del país. Se incluyeron pacientes con criterios de sepsis asociada a ureterolitiasis confirmada radiológicamente. Se registraron sus datos demográficos, signos vitales y laboratorio de ingreso, así como sus estudios microbiológicos y radiológicos, realizándose estadísticas descriptivas de los datos obtenidos. RESULTADOS: Se ingresaron 119 pacientes, de los cuales 52 cumplieron criterios de inclusión. 77% eran mujeres, con una edad promedio de 52 años. Se tomaron hemocultivos en el 48,7% de los casos y urocultivos en el 100%. El microorganismo más común fue Escherichia coli (73%), seguido por Proteus mirabilis (9,6%) y Klebsiella pneumoniae (3,9%). Hubo dos casos de bacterias gram positivas. El 100% de las bacterias gram negativas fueron sensibles a amikacina. CONCLUSIÓN: Los microorganismos encontrados en nuestra cohorte fueron similares a los de los estudios internacionales. Dado que el mayor nivel de susceptibilidad fue para amikacina, proponemos su uso como terapia empírica para la urosepsis asociada a ureterolitiasis en Chile. Siempre es necesario considerar los posibles efectos ne-frotóxicos de la amikacina. Se debe considerar una asociación de betalactámicos y glicopéptidos en pacientes con factores de riesgo de infecciones enterocócicas.
BACKGROUND: Inadequate antibiotic coverage in septic patients is associated with higher morbidity and mortality. This multicentric study reports antibiotic susceptibility in patients with ureterolithiasis-associated urosepsis, aiming to propose an optimal empirical therapy for this disease in the Chilean population. METHODS: The prospective cohort study included patients from 7 Chilean hospitals who presented with ureterolithiasis and met sepsis criteria. We analyzed demographic data, vital signs at admission, and microbiological and radiological exams. We used descriptive statistics for the analysis of collected data. Results: Initially, the study included 119 patients; 52 met the inclusion criteria. 77% were female, with a mean age of 52. 100% of the cohort had a urine culture taken at admission, whereas 48,7% had blood cultures. Escherichia Coli was the most common microorganism (73%), followed by Proteus Mirabilis (9.6%) and Klebsiella Pneumoniae (3.9%). Only two patients presented gram-positive pathogens. 100% of gram-negative bacteria were sensible to amikacin. CONCLUSION: The microorganisms found in our cohort were similar to those in international reports. Since the highest level of susceptibility was for amikacin, we propose its use as empirical therapy for urosepsis associated with ureterolithiasis in Chile. It is always necessary to consider the potential nephrotoxic effects of amikacin. An association of beta-lactams and glycopeptides should be considered in patients with risk factors for enterococcal infections.

INTRODUCTION: Urinary lithiasis is the main urologic cause of emergency treatment in adult patient. In the past years, the incidence in children population has increased. However, literature about the use of alpha-1 adrenergic blockers in pediatric population with distal ureterolithiasis is still scarce. The drug acts by decreasing ureter contractions, especially in the distal portion, facilitating calculus expulsion. OBJECTIVE: This review has the objective to evaluate the use of alpha-1 adrenergic blockers as medical expulsive treatment in children with distal ureterolithiasis. EVIDENCE ACQUISITION: An electronic literature search was performed using the MEDLINE, COCHRANE, and LILACS databases. We further searched manually the references of the primary studies. Searches were concluded on October 4th, 2014. Articles were selected, independently and in pairs, by the respective titles and summaries. Any divergence was resolved by consensus. EVIDENCE SYNTHESIS: Alpha-1 adrenergic antagonists increased the probability of calculus expulsion by 27% (NNT=4). Calculi smaller than 5mm, increased by 33% (NNT=3). Larger than 5mm, increased by 34% (NNT=3). CONCLUSION: Alpha-1 adrenergic blocker use is related with a greater incidence of expulsion of ureteral calculi, smaller or greater than 5mm, and fewer episodes of pain when compared to ibuprofen. However it is necessary larger samples to enhance the power analysis of the expulsion of ureteral calculi larger than 5mm and the episodes of pain. PATIENT SUMMARY: This review analyzed the outcome of alpha adrenergic antagonist in children with ureteral calculi. We conclude that it is the best medicine for use, since it helps the expulsion of the stone.
