ABSTRACT
PURPOSE: To evaluate the influence of the urologist's experience on the surgical results and complications of transurethral resection of the prostate (TURP). PATIENTS AND METHODS: Sixty-seven patients undergoing transurethral resection of the prostate without the use of a video camera were randomly allocated into three groups according to the urologist's experience: a urologist having done 25 transurethral resections of the prostate (Group I - 24 patients); a urologist having done 50 transurethral resections of the prostate (Group II - 24 patients); a senior urologist with vast transurethral resection of the prostate experience (Group III - 19 patients). The following were recorded: the weight of resected tissue, the duration of the resection procedure, the volume of irrigation used, the amount of irrigation absorbed and the hemoglobin and sodium levels in the serum during the procedure. RESULTS: There were no differences between the groups in the amount of irrigation fluid used per operation, the amount of irrigation fluid absorbed or hematocrit and hemoglobin variation during the procedure. The weight of resected tissue per minute was approximately four times higher in group III than in groups I and II. The mean absorbed irrigation fluid was similar between the groups, with no statistical difference between them (p=0.24). Four patients (6 percent) presented with TUR syndrome, without a significant difference between the groups. CONCLUSION: The senior urologist was capable of resecting four times more tissue per time unit than the more inexperienced surgeons. Therefore, a surgeon's experience may be important to reduce the risk of secondary TURP due to recurring adenomas or adenomas that were incompletely resected. However, the incidence of complications was the same between the three groups.

Los edulcorantes son productos útiles empleados muy comúnmente en la alimentación de los pacientes diabéticos y en regímenes hipocalóricos. Se presenta un análisis crítico de los diferentes edulcorantes calóricos y no calóricos actualmente disponibles en el mercado nacional analizando el aporte energético así como las ventajas y desventajas de cada uno de ellos. Se describen las características químicas y metabólicas del aspartame, endulzante no calórico y se comentan las investigaciones que se realizaron para lograr la autorización de su uso por la Federal Drug Administration (FDA). Se hace énfasis en que el profesional de la salud, debe tener conocimientos sobre los edulcorantes y productos dietéticos, a objeto de instruir a los pacientes para la correcta selección de ellos
