[Critical analysis of the bibliography of Actas Urológicas Españolas]. / Análisis crítico de la bibliografía de Actas Urológicas Españolas.

In the absence of Spanish journals and publications with a high impact factor and since one of the primary reasons to obtain such an impact is the frequency with which the publication is referenced, we wanted to check the general belief by which even in the Spanish journals the proportion of national articles that get referenced is very small. We reviewed all articles published by Actas Urológicas Españolas during 1989 and 1990 (12 issues, 246 articles with 4,549 references), and found that only 14.42% of references were from publications or books edited in Spain or at congresses held within Spain. After excluding books and communications originates in congresses, the figure is 10.9%. On the other hand, we noticed that over 25% articles do not include one single Spanish reference. Finally, the publication most often consulted is the USA Journal of Urology, which approaches some 20% of all mentions.

[Accidentally diagnosed hypernephromas. Retrospective study and evaluation of their importance in clinical practice]. / Hipernefromas de diagnóstico accidental. Estudio retrospectivo y evaluación de su importancia en la práctica clinica.

Presentation of a retrospective study on 50 hypernephromas seen in our service, including an evaluation of those that were accidentally diagnosed. Nineteen of these were diagnosed by chance and 9 as a result of other investigations required for the study of a gastrointestinal disease, these studies being in most cases an ultrasound recording. Data obtained with this review allows us to compare these results with those from other authors, as well as to evaluate the relevance of such diagnoses in the daily clinical practice. The study concludes that the fact that these tumours are found in earlier stages is more than enough to raise questions on the way in which we could increase the number of this chance diagnosis.
