Case Reports

Would authors please note that there has been a change in editorial policy and the Journal will no longer accept Case Reports, with immediate effect. Any Case Reports submitted will be returned to the authors without review.*

*Authors may wish to consider submitting Case Reports to a dedicated publication such as International Journal of Surgery Case Reports. This is an online-only, open access journal, funded by article publication charges; see www.casereports.com for details.

Authorship
All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

Acknowledgements
All contributors who do not meet the criteria for authorship as defined above should be listed in an acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose whether they had any writing assistance and identify the entity that paid for this assistance.

Conflict of Interest Statement
The potential for conflict of interest exists when an author (or the author s institution), reviewer or editor has financial or personal relationships that may inappropriately influence his or her actions. Editors and reviewers for the journal are responsible for disclosing to the Editor-in-Chief any personal or financial relationship that may bias their work during the peer review process. Corresponding authors are required to submit a conflict of interest statement as a separate submission item. Where an author has no competing interests, they must nonetheless provide a statement to confirm this. The Editor-in-Chief reserves the right to publish all declared competing interests. Authors are specifically asked to reflect on financial conflicts of interest (such as employment, consultancy, stock ownership, honoraria and paid expert testimony) as well as other forms of conflict of interest, including personal, academic and intellectual issues. Authors will not be able to complete their submission without providing a conflict of interest statement. For queries, please contact the journal editorial office directly: jpurol@elsevier.com

Role of the Funding Source
All sources of funding should be declared as an acknowledgement at the end of the text. Authors should declare the role of study sponsors, if any, in the study design, in the collection, analysis and interpretation of data; in the writing of the manuscript; and in the decision to submit the manuscript for publication. If the study sponsors had no such involvement, the authors should so state.

Open access
This journal offers you the option of making your article freely available to all via the ScienceDirect platform. To prevent any conflict of interest, you can only make this choice after receiving notification that your article has been accepted for publication. The fee of $3,000 excludes taxes and other potential author fees such as color charges. In some cases, institutions and funding bodies have entered into agreement with Elsevier to meet these fees on behalf of their authors. Details of these agreements are available at http://www.elsevier.com/fundingbodies. Authors of accepted articles, who wish to take advantage of this option, should complete and submit the order form (available at http://www.elsevier.com/locate/openaccessform.pdf). Whatever access option you choose, you retain many rights as an author, including the right to post a revised personal version of your article on your own website. More information can be found here: http://www.elsevier.com/authorsrights.

Randomised Controlled Trials
All randomised controlled trials submitted for publication in the Journal of Pediatric Urology should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart. Please refer to the CONSORT statement website at http://www.consort-statement.org for more information. The Journal of Pediatric Urology has adopted the proposal from the ICMJE which require, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Trials must register at or before the onset of patient enrolment. The clinical trial registration number (ISRCTN) should be included at the end of the abstract of the article. For this purpose, a clinical trial is defined as any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g. phase I trials) would be exempt. Further information can be found at http://www.icmje.org.

Ethics
Work on human beings that is submitted to the Journal of Pediatric Urology should comply with the principles laid down in the Declaration of Helsinki (Recommendations guiding physicians in biomedical research involving human subjects. Adopted by the 18th World Medical Assembly, Helsinki, Finland, June 1964, amended by the 29th World Medical Assembly, Tokyo, Japan, October 1975, the 35th World Medical Assembly, Venice, Italy, October 1983, and the 41st World Medical Assembly, Hong Kong, September 1989). The manuscript should contain a statement that the work has been approved by the appropriate ethical committees related to the institution(s) in which it was performed and that subjects gave informed consent to the work. Patients and volunteers names, initials, and hospital numbers should not be used.

Animal experiments require full compliance with local, national, ethical, and regulatory principles, and local licensing arrangements, and the journal will not accept papers for publication if doubts exist over the standards of care and humanity shown to experimental animals. For this reason a clear statement of the care principles used should be included in the text.

Guidelines on publication ethics adhered to by this journal are to be found at the Committee on Publication Ethics (COPE) website at http://www.publicationethics.org.uk.

Submission of articles
Submission and peer review of all papers is now conducted entirely online, increasing efficiency for editors, authors, and reviewers, and enhancing publication speed. Authors requesting further information on online submission are strongly encouraged to view the system, including a tutorial, at http://ees.elsevier.com/jpurol.

Author Support is also available on http://support.elsevier.com

It is essential to give a fax number and e-mail address when submitting a manuscript. Articles must be written in good English.

Copyright
Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the copyright-holder.

Upon acceptance of an article, authors will be asked to sign a Journal Publishing Agreement (for more information on this and copyright see http://www.elsevier.com/authors). Acceptance of the agreement will ensure the widest possible dissemination of information.

Preparation of text

Electronic format requirements for accepted articles
Wordprocessor documents
It is important that the file be saved in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as possible. In particular, do not use the wordprocessors options to justify text or to hyphenate words. You may use bold face, italics, subscripts, superscripts, etc. Do not embed graphically designed equations or tables, but prepare these using the wordprocessor s facility. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. Do not import the figures into the text file but, instead, indicate their approximate locations directly in the electronic text. See also the section on Preparation of electronic illustrations. To avoid unnecessary errors you are strongly advised to use the spellchecker function of your wordprocessor.

LaTeX documents
The Elsevier LaTeX package (including detailed instructions for LaTeX preparation) can be obtained from: http://www.elsevier.com/wps/find/authorsview.authors/latex

Presentation of manuscript
General Please write your text in good English (American or British usage is accepted, but not a mixture of these). Italics are to be used for expressions of Latin origin; for example, in vivo, et al., per se. Use decimal points (not commas); use a space for thousands (10 000 and above).

For authors in Japan: upon request, Elsevier Japan will provide a list of people who can check and improve the English of an article before submission. Contact our Tokyo office: Elsevier K.K., Editorial Service, 1-9-15 Higashi Azabu, Minato-ku, Tokyo 106-0044, Japan; tel: +81-3-5561-5032; fax: +81-3-5561-5045; e-mail: info@elsevier.co.jp

Type the entire manuscript using double spacing and wide (3 cm) margins. (Avoid full justification, i.e. do not use a constant right-hand margin.) Ensure that each new paragraph is clearly indicated. Present tables and figure legends on separate pages at the end of the manuscript. Consult a recent issue of the journal to become familiar with layout and conventions. Number all pages consecutively.

Provide the following data on the title page (in the order given).

Title: Concise and informative. Avoid abbreviations and formulae where possible.
• Author names and affiliations: Where the family name may be ambiguous (e.g. a double name), please indicate this clearly. Present the authors affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author s name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and the e-mail address of each author.
• Corresponding author: Clearly indicate who is willing to handle correspondence at all stages of refereeing and publication, and post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.
• Present/permanent address: If an author has moved since the work described in the article was done, or was visiting at the time, a `present address (or `permanent address ) may be indicated as a footnote to that author s name. The address at which the author actually did the work must be retained as the main affiliation address.

Abstract: A concise and factual abstract is required of no more than 200 words, sub-divided into an objective (a short statement of the aims, not a long paragraph of background information), subjects/patients (or materials) and methods, the results (no long lists of detailed values, but stating the main findings) and a conclusion, essentially assessing whether the aims have been met. References should be avoided, but if essential, they must be cited in full. Non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

Keywords: Immediately after the abstract, provide a list of 3-6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, `and , `of ). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

Abbreviations: Define abbreviations that are not standard in this field at their first occurrence in the article. Ensure consistency of abbreviations throughout the article.

Arrangement of the article

Introduction: State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Experimental/Materials and methods: Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.

Results

Discussion: This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

Conclusions: The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Nomenclature: Please supply, as a separate list, the definitions of field-specific terms used in your article.

Appendices: If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: (Eq. A.1), (Eq. A.2), etc.; in a subsequent appendix, (Eq. B.1) and so forth.

Acknowledgements: Place acknowledgements, including information on grants received, before the references, in a separate section, and not as a footnote on the title page.

References: See separate section below.

Figure legends, tables, figures, schemes: Present these, in this order, at the end of the article. They are described in more detail below. High-resolution graphics files must always be provided separate from the main text file (see Preparation of illustrations).

Text graphics: Present incidental graphics not suitable for mention as figures, plates or schemes at the end of the article and number them `Graphic 1 , etc. Their precise position in the text can then be defined similarly. See further under the section, Preparation of illustrations. Ensure that high-resolution graphics files are provided, even if the graphic appears as part of your normal wordprocessed text file.

Specific remarks

Tables: Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.

Nomenclature and units: Follow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI.

Supplementary data (including multimedia and video:) The journal accepts electronic supplementary material to support and enhance your scientific research. Supplementary files allow the author to submit supporting applications, movies, animation sequences, high-resolution images, background datasets, sound clips and more, which will be published online alongside the electronic version of your article. In order to ensure that your submitted material is directly usable, please ensure that data is provided in one of the recommended file formats (for detailed guidance on formats for supplementary files, including movies, go to http://www.elsevier.com/framework_authors/Artwork/Multimedia_2010.pdf).

References

Responsibility for the accuracy of bibliographic citations lies entirely with the authors.

Citations in the text: Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications should not be in the reference list, but may be mentioned in the text. Citation of a reference as `in press implies that the item has been accepted for publication. Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given. At the end of the text, list the references in the order in which they appear in the text.

Citing and listing of web references: As a minimum, the full URL should be given. Any further information, if known (author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g. after the reference list) under a different heading if desired, or can be included in the reference list.
