[Analysis of the absorcion's factors of irrigating fluid during transurethral resection of the prostate]. / Análisis de los factores de reabsorción de líquido de irrigación durante la RTU de próstata.

OBJECTIVES: In this study it was our intention to evaluate the relation between the reabsorption of irrigating fluid and three variables: time of the intervention, volume of solution of glicina employee and weight of the fragments, during the RTU of prostate fulfilled to low hydraulic pressure. MATERIAL AND METHOD: We study 74 patients that RTU of prostate was performed with suprapúbica derivation with Amplatz's pod 30 ch. The ethanol was monitored in expired air every 15 minutes during the intervention. Likewise we annotated the time of the intervention, the volume of glicina used and the weight of the fragments extracted. Statistically Anova's text was in use for comparison of averages. RESULTS: 13,6% of the patients absorbed irrigating fluid in some quantity. The range of absorption belongs to 100 cc until 2.000 cc. We did not find a statistically significant difference in the averages of time of resection, volume of glicina and weight of the fragments between the group of patients that had absortion of irrigating fluid and they that didn't had. CONCLUSIONS: Our data show that the operative time, the volume of irrigating fluid and the weight of the resected fragments do not influence the reabsorption of liquid of irrigation when a RTU is realized to low hydraulic pressure.

Análisis de los factores de reabsorción de líquido de irrigación durante la RTU de próstata / Analysis of the absorcion´s factors of irrigating fluid during transurethral resection of the prostate

Objetivos: En este estudio fue nuestra intención evaluar la relación entre la reabsorción de líquido de irrigación y tres variables: tiempo de la intervención, volumen de solución de glicina empleado y peso de los fragmentos, durante la RTU de próstata realizada a baja presión hidráulica. Material y método: Estudiamos 74 pacientes a los que se realizó RTU de próstata con derivación suprapúbica con vaina de Amplatz 30 ch. Se monitorizó el etanol en aire expirado cada 15 minutos durante la intervención. Así mismo se anotaron el tiempo de la intervención, el volumen de glicina utilizado y el peso de los fragmentos extraídos. Estadísticamente se utilizó el Test de Anova para comparación de medias. Resultados: Un 13,6 % de los pacientes absorbieron líquido de irrigación en alguna cantidad. El rango de absorción es de 100 cc hasta 2.000 cc. No se encontró una diferencia estadísticamente significativa entre las medias del tiempo de resección, del volumen de glicina y del peso de los fragmentos entre el grupo de pacientes que había reabsorbido líquido de irrigación y los que no reabsorbieron. Conclusiones: Nuestro estudio pone de manifiesto que el tiempo operatorio, el volumen de líquido de irrigación y el peso de los fragmentos resecados no influyen en la reabsorción de líquido de irrigación cuando se realiza una RTU a baja presión hidráulica (AU)

[Quality analysis of the statistical used resources (material and methods section) in thesis projects of a university department]. / Análisis de calidad de los recursos estadísticos (sección material y método) en los proyectos de tesis de un departamento universitario.

INTRODUCTION AND OBJECTIVES: Studies about quality in thesis and investigation projects in biomedical sciences are unusual, but very important in university teaching because is necessary to improve the quality elaboration of the thesis. The objectives the study were to determine the project's quality of thesis in our department, according to the fulfillment of the scientific methodology and to establish, if it exists, a relation between the global quality of the project and the statistical used resources. MATERIAL AND METHODS: Descriptive study of 273 thesis projects performed between 1995-2002 in surgery department of the Zaragoza University. The review realized for 15 observers that they analyzed 28 indicators of every project. Giving a value to each of the indicators, the projects qualified in a scale from 1 to 10 according to the quality in the fulfillment of the scientific methodology. RESULTS: The mean of the project's quality was 5.53 (D.E: 1.77). In 13.9% the thesis projects was concluded with the reading of the work. The three indicators of statistical used resources had a significant difference with the value of the quality projects. DISCUSSION: The quality of the statistical resources is very important when a project of thesis wants to be realized by good methodology, because it assures to come to certain conclusions. In our study we have thought that more of the third part of the variability in the quality of the project of thesis explains for three statistical above-mentioned articles.

Análisis de calidad de los recursos estadísticos (sección material y método) en los proyectos de tesis de un departamento universitario / Quality analysis of the statistical used resources (material and methods section) in thesis projects of a universitary department

INTRODUCCIÓN Y OBJETIVOS: Los estudios sobre la calidad de tesis y proyectos de investigación en ciencias biomédicas son muy escasos, pero de enorme interés para la docencia universitaria, por la necesidad académica de mejorar la calidad del proceso de elaboración de la tesis. Los objetivos del estudio fueron determinar la calidad de los proyectos de tesis de nuestro departamento, según el cumplimiento de la metodología científica y establecer, si existe, una relación entre la calidad global del proyecto y los recursos estadísticos utilizados. MATERIAL Y MÉTODO: Estudio descriptivo en el que se analizaron 273 proyectos de tesis realizados entre 1995 y 2002 en el departamento de Cirugía de la Universidad de Zaragoza. La revisión se realizó por 15 observadores que analizaron 28 indicadores de cada proyecto. Dando un valor ponderado a cada uno de los indicadores, se calificaron los proyectos en una escala de 0 a 10 según la calidad en el cumplimiento de la metodología científica. RESULTADOS: La media de las calificaciones de los proyectos fue de 5,53 (D.E: 1,77.) Un 13,9% de los proyectos de tesis se concluyeron con la defensa y lectura del trabajo. En los tres indicadores de recursos estadísticos se encontró una diferencia estadísticamente significativa con la valoración de la calidad de los proyectos. DISCUSIÓN: La calidad de los recursos estadísticos es de suma importancia cuando se quiere realizar un proyecto de tesis con buena metodología, ya que asegura llegar a conclusiones ciertas. En nuestro estudio hemos encontrado que más de la tercera parte de la variabilidad en la calidad del proyecto de tesis se explica por los tres ítems estadísticos referidos
