Abstract

Objective: To determine the actual etiology and clinical characteristics of male urethral stricture and stenosis in a highly complexity institution.

Method: Observational, descriptive cross-sectional study. Information was collected from 344 patients with urethral stricture or stenosis who underwent urethroplasty between January 2011 and March 2019. Age, etiology, compromised urethral site, length of the stricture, previous procedures and surgery performed were considered for each patient.

Results: The median age was 59.6 years (range 14-90 years). The most common etiology was iatrogenic 68.1%, followed by inflammatory 13.9%, idiopathic 12.2% and traumatic 5.5%. Of the iatrogenic causes, 39.2% were secondary to urethral instrumentation, 20.6% endoscopic prostate surgery, 4.3% post-hypospadias surgery, 2.3% other, and 1.7% open prostate surgery. When stratifying by age, the most common etiology of stricture was iatrogenic in all three age groups: in the 0-45 years group (32.6%), in the 46-59 years group (63.3%) and in the group of over 60 years (83.4%).

Conclusion: Urethral stricture is a pathology that occurs more and more frequently in daily urological practice, it is not a disease of the elderly but involves all ages. Currently, the main cause is iatrogenic etiology, for which reason we are obliged to improve prevention strategies.

    Editorial times

    The editorial process consists of 6 stages:

    1. Reception of the manuscript (indeterminate, depending on whether the author meets the requirements): its objective is to verify that the manuscript complies with the specifications of these instructions for authors and that the submitted documentation is complete.

    2. Initial editorial review (maximum 5 business days): its objective is to corroborate the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical soundness of the study. At this time, it will be submitted to an electronic plagiarism detection system. Derived from this, a rejected opinion may be obtained, or it will be sent for review by peer researchers.

    3. Review by peer researchers (maximum 30 business days): the opinion of at least two experts in the area in question will be obtained, who will evaluate the technical and methodological aspects of the investigation.

    4. Editorial review (maximum 7 business days): its objective is to make a decision based on the opinion of peer reviewers. The opinion can be rejected, major changes, minor changes or accepted. In the case of major or minor changes, it will be submitted again for evaluation by the initial peer reviewers.

    5. Final edition (6 weeks): its objective is the technical and linguistic edition (and translation), layout of galleys, DOI assignment, and correction by the author.

    6. Advanced publication: All manuscripts will be published ahead of print on the journal’s website as soon as they complete the editing process, until they are incorporated into a final issue of the journal.
