2. EDITORIAL REVIEW AND ACCEPTANCE

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.

4. DISCLOSURE

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.

5. ETHICAL CONSIDERATIONS

ETHICAL CONSIDERATIONS
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: http://www.wma.net/en/30publications/10policies/b3/. 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.
REGISTRY OF RESEARCH STUDIES INVOLVING HUMAN SUBJECTS
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).

6. CLINICAL TRIALS REGISTRY

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 (https://clinicaltrials.gov/);
(2) International Standard Randomized Controlled Trial Number Registry (http://www.controlled-trials.com);
(3) Australian Clinical Trials Registry (https://www.australianclinicaltrials.gov.au/clinical-trial-registries);
(4) Chinese Clinical Trials Register (http://www.chictr.org.cn/enIndex.aspx);
(5) Clinical Trials Registry India (http://www.ctri.in); and
(6) University hospital Medical Information Network (UMIN) (http://www.umin.ac.jp/ctr/)

7. RANDOMIZED CONTROLLED TRIALS

Reporting of randomized controlled trials should follow the guidelines of The CONSORT Statement: http://www.consort-statement.org

17. TRACKING MANUSCRIPTS

BEFORE ACCEPTANCE
Authors can track your manuscript's progress through the review process at: http://mc.manuscriptcentral.com/iju
AFTER ACCEPTANCE
Author Services enables authors to track their article, once it has been accepted, through the production process to publication online and in print. Authors can check the status of their articles online and choose to receive automated emails at key stages of production so they do not need to contact the Production Editor to check on progress. For more details on online production tracking and for a wealth of resources, including FAQs and tips on article preparation, submission and more, visit: http://authorservices.wiley.com/bauthor

18. ONLINE OPEN

OnlineOpen is available to authors of primary research articles who wish to make their article available to non-subscribers on publication, or whose funding agency requires grantees to archive the final version of their article. With OnlineOpen the author, the author's funding agency, or the author's institution pays a fee to ensure that the article is made available to non-subscribers upon publication via Wiley Online Library, as well as deposited in the funding agency's preferred archive. For the full list of terms and conditions: http://wileyonlinelibrary.com/onlineopen#OnlineOpen_Terms
Any authors wishing to send their paper OnlineOpen will be required to complete the payment form available from our website at: https://authorservices.wiley.com/bauthor/onlineopen_order.asp
Prior to acceptance there is no requirement to inform an Editorial Office that you intend to publish your paper OnlineOpen if you do not wish to. All OnlineOpen articles are treated in the same way as any other article. They go through the journal's standard peer-review process and will be accepted or rejected based on their own merit.

19. EARLYVIEW

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: http://www.doi.org/faq.html
