The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are single-blind peer reviewed by two or more anonymous reviewers and the Editor. The Editorial Board reserves the right to refuse any material for publication and advises that authors should retain copies of submitted manuscripts and correspondence as material cannot be returned. Final acceptance or rejection rests with the Editorial Board.
All manuscripts should be written so that they are intelligible to the professional reader who is not a specialist in the particular field. They should be written in a clear, concise, direct style. Where contributions are judged as acceptable for publication on the basis of urologic content, the Editor and the Publisher reserve the right to modify manuscripts to eliminate ambiguity and repetition and improve communication between author and reader. If extensive alterations are required, the manuscript will be returned to the author for revision. Authorship must be finalized during the submission process. Please ensure that all authors are listed and in the correct order, because changes are not permissible once the accepted manuscript goes into production.

Both solicited and unsolicited articles will undergo peer review prior to acceptance.


Conflicts of interest: Authors should declare relationships that may pose any conflicts of interest as a Conflict of Interest statement in the CONFLICTS OF INTEREST section within the manuscript.
Financial support: Authors are required to identify explicitly all sources of funding. If the research reported in the manuscript has received partial or complete funding from commercial sponsors, the authors must also include a statement to that effect. The existence of financial support is not an impediment to publication; however, the disclosure of funding is mandatory and should be indicated in the ACKNOWLEDGEMENT section within the manuscript.


Authors must state that the protocol for the research project has been approved by a suitably constituted Ethics Committee of the institution within which the work was undertaken and that it conforms to the provisions of the Declaration of Helsinki (as revised in Fortaleza, Brazil, October 2013), available at: In general, submission of a case report should be accompanied by the written consent of the subject (or parent/guardian) before publication; this is particularly important where photographs are to be used or in cases where the unique nature of the incident reported makes it possible for the patient to be identified. While the Editors recognize that it might not always be possible or appropriate to seek such consent, the onus will be on the authors to demonstrate that this exception applies in their case. Any experiments involving animals must be demonstrated to be ethically acceptable and where relevant conform to national guidelines for animal usage in research. IJU retains the right to reject any manuscript on the basis of unethical conduct of either human or animal studies.
As shown in the Declaration of Helsinki (Fortaleza, Brazil, October 2013), every research study involving human subjects must be registered in a publicly accessible database before recruitment of the first subject. Thus any research project that assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome must be registered. The above policy applies to every research study which began with enrollment of patients after November 1st 2013 (If authors are considering submitting a non-registered prospectively designed research study, please explain the reason why it has not been registered. Registration of retrospective studies is not required, but must have official approval from an appropriate ethical committee at submission of the study).


We strongly recommend, as a condition of consideration for publication, registration in a public trials registry. Trials register at or before the onset of patient enrollment. This policy applies to any clinical trial starting enrollment after January 1, 2006. For trials that began enrollment before this date, we request registration by April 1, 2006, before considering the trial for publication. We define a clinical trial 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 studies on pharmacokinetics or major toxicity (e.g., phase 1 trials), are exempt.
We do not advocate any particular registry, but registration with a registry should meet the following minimum criteria: (1) accessible to the public at no charge; (2) searchable by standard, electronic (Internet-based) methods; (3) open to all prospective registrants free-of-charge or at minimal cost; (4) validate registered information; (5) identify trials with a unique number; and (6) include information on the investigator(s), research question or hypothesis, methodology, intervention and comparisons, eligibility criteria, primary and secondary outcomes measured, date of registration, anticipated or actual start date, anticipated or actual date of last follow-up, target number of subjects, status (anticipated, ongoing or closed) and funding source(s).
Registries that currently meet these criteria include:
(1) registry sponsored by the United States National Library of Medicine (;
(2) International Standard Randomized Controlled Trial Number Registry (;
(3) Australian Clinical Trials Registry (;
(4) Chinese Clinical Trials Register (;
(5) Clinical Trials Registry India (; and
(6) University hospital Medical Information Network (UMIN) (


Reporting of randomized controlled trials should follow the guidelines of The CONSORT Statement:

Papers accepted for publication in IJU become copyright of The Japanese Urological Association. Papers need to be submitted with a signed Author Submission Requirement Form that includes transfer of copyright. In signing the Author Submission Requirement Form, it is assumed that authors have obtained permission to use any copyrighted or previously published materials. All authors must read and agree to the conditions outlined in the Author Submission Requirement Form, and must sign the Form or agree that the corresponding author can sign on their behalf.

NIH Public Access Mandate: For those interested in our policy on the NIH Public Access Mandate, please consults our policy statement:

Manuscripts must follow the style detailed in the International Committee of Medical Journal Editors’ revised ‘Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication’, as presented at:

Spelling: The Journal uses US spelling and authors should therefore follow the latest edi-tion of the Merriam–Webster’s Collegiate Dictionary.
Units: All measurements must be given in SI or SI-derived units. For more information about SI units, please go to the Bureau International des Poids et Mesures (BIPM) website at:
Abbreviations & acronyms: Must be used sparingly – only where they ease the reader’s task by reducing repetition of long, technical terms. Abbreviations and acronyms are not allowed in the article title and abstract. For the main text, author can use abbreviations and acronyms, and must provide a list of abbreviated words in the manuscript. This is not applicable for Editorials, Editorial Comment, Letters to the Editor articles.
Trade names: Drugs should be referred to by their generic names. If proprietary drugs have been used in the study, refer to these by their generic name, mentioning the proprietary name, and the name and location of the manufacturer, in parentheses.

The length of manuscripts must adhere to the specifications under the section Manuscript Categories.
Manuscripts should be presented in the following order: (i) title page, (ii) abstract and key words, (iii) text, (iv) acknowledgments, (v) conflicts of interest, (vi) references, (vii) supporting information, (viii) figure legends, (ix) tables (each table complete with title and footnotes) and (x) figures. Footnotes to the text are not allowed and any such material should be incorporated into the text as parenthetical matter.

The title page should contain (i) title of the paper, (ii) full names of the authors and (iii) addresses of the institutions at which the work was carried out together with (iv) the full postal and email address, plus facsimile and telephone numbers, of the author to whom correspondence about the manuscript should be sent, and (v) a word count.
The present address of any author, if different from that where the work was carried out, should be supplied in a footnote. In keeping with the latest guidelines of the International Committee of Medical Journal Editors, each author’s contribution to the paper is to be quantified. The title should be short, informative and contain the major key words so that readers and in particular online users will discover the article easily during online search. Do not use abbreviations in the title. A short running title (less than 40 characters) should also be provided. The running title is the short title found at the top right-hand corner of the article to help article search.

The length of abstracts must adhere to the specifications under the section Manuscript Categories. Please note that the requirements differ between manuscript types. The abstract should not contain abbreviations or references. Five key words, for the purposes of indexing, should be supplied below the abstract, in alphabetical order, and should be taken from those recommended by the US National Library of Medicine’s Medical Subject Headings (MeSH) browser list at:

Please note that the requirements differ between manuscript types. Please refer to Manuscript Categories for individual requirements.

Sources of financial grants and other funding must be acknowledged, including a frank declaration of the authors’ industrial links and affiliations. The contribution of colleagues or institutions should also be acknowledged. Thanks to anonymous reviewers are not appropriate.

Authors are required to disclose any conflicts of interest. The statement should be the same as on the Author Submission Requirement Form. The absence of any interest to disclose must also be stated.

The Vancouver system of referencing should be used (examples are given below). In the text, references should be cited using super-script Arabic numerals in the order in which they appear. If cited in tables or figure legends, number according to the first identification of the table or figure in the text. In the reference list, cite the names of all authors when there are six or fewer; when seven or more, list the first three followed by et al. Do not use ibid. or op cit. Reference to un-published data and personal communications should not appear in the list but should be cited in the text only (e.g. Smith A, 2000, un-published data). All citations mentioned in the text, tables or figures must be listed in the reference list. Names of journals should be abbreviated in the style used in Index Medicus. Authors are responsible for the accuracy of the references.

Supporting Information is provided by the authors to support the content of an article but they are not integral to that article. They are hosted via a link on Wiley Online Library, but do not appear in the print version of the article. Supporting Information must be submitted together with the article for re-view; they should not be added at a later stage. They can be in the form of tables, fig-ures, appendices and even video footage. Reference to Supporting Information in the main body of the article is allowed. Howev-er, it should be noted that excessive refer-ence to a piece of Supporting Information may indicate that it would be better suited as a proper reference or fully included fig-ure/table. The materials will be published as they are supplied and will not be checked or typeset in any way. All Supporting Infor-mation files should come with a legend, listed at the end of the main article. Each figure and table file should not be larger than 5MB, although video files may be larger. Prior to submission, please check the guidelines at:

Manuscripts must be submitted online at: Authors must supply an email address as all correspondence will be by email.

All articles submitted to the Journal must comply with these instructions. Failure to do so will result in return of the manuscript and possible delay in publication.
• Submissions must be double-spaced.
• All margins should be at least 30 mm.
• All pages should be numbered consecutively in the top right-hand corner, beginning with

EarlyView articles are complete full-text articles published online in advance of their publication in a printed issue. Articles are therefore available as soon as they are ready, rather than having to wait for the next scheduled print issue. EarlyView articles are complete and final. They have been fully reviewed, revised and edited for publication, and the authors’ final corrections have been incorporated. Because they are in final form, no changes can be made after online publication. The nature of EarlyView articles means that they do not yet have volume, is-sue or page numbers, so EarlyView articles cannot be cited in the traditional way. They are therefore given a Digital Object Identifier (DOI), which allows the article to be cited and tracked before it is allocated to an issue. After print publication, the DOI remains valid and can continue to be used to cite and ac-cess the article. More information about DOIs can be found at:
