Publication of original research in urologic journals--a neglected orphan?

The pathophysiologic mechanisms behind urologic disease are increasingly being elucidated. The object of this investigation was to evaluate the publication policies of urologic journals during a period of progressively better understanding and management of urologic disease. Based on the ISI Web of Knowledge Journal Citation Reports and the PubMed database, the number and percentage of original experimental, original clinical, review or commentarial articles published between 2002-2010 in six leading urologic journals were analyzed. "British Journal of Urology International", "European Urology", "Urologic Oncology-Seminars and Original Investigations" ("Urologic Oncology"), "Urology", "The Journal of Urology", and "World Journal of Urology" were chosen, because these journals publish articles in all four categories. The publication policies of the six journals were very heterogeneous during the time period from 2002 to 2010. The percentage of original experimental and original clinical articles, related to all categories, remained the same in "British Journal of Urology International", "Urologic Oncology", "Urology" and "The Journal of Urology". The percentage of experimental reports in "World Journal of Urology" between 2002-2010 significantly increased from 10 to 20%. A distinct elevation in the percentage of commentarial articles accompanied by a reduction of clinical articles became evident in "European Urology" which significantly correlated with a large increase in the journal's impact factor. No clearly superior policy could be identified with regard to a general increase in the impact factors from all the journals. The publication policy of urologic journals does not expressly reflect the increase in scientific knowledge, which has occurred over the period 2002-2010. One way of increasing the exposure of urologists to research and expand the interface between experimental and clinical research, would be to enlarge the percentage of experimental articles published. There is no indication that such policy would be detrimental to a journal's impact factor.
