Management of male posterior urethral stenosis following trauma and prostatic treatments, techniques and results
Bibliographic record
Abstract
Posterior Urethral Stenosis (PUS) is a surgical challenge. The aim of this article is to summarize current knowledge on the management of PUS. A comprehensive literature review was conducted using the PubMed database, covering the period from 2020 to 2023. To supplement this review, recommendations from the American Urological Association (AUA), European Association of Urology (EAU), and Canadian Urological Association (CUA), along with several key reference surgical guides, were incorporated. The collected data was then summarized by etiology to provide a detailed analysis. Pelvic Fracture Urethral Injury (PFUI) is a frequent complication of pelvic fractures. Treatments are well-established, including early realignment and excision-primary-anastomosis (EPA). Stenosis following treatment for benign prostatic hyperplasia (BPH) presents specific challenges due to the high risk of urinary incontinence. The management of post-prostatectomy stenoses stenosis depends on the stricture's location and may involve endoscopic treatment or complex reconstruction. Stenosis following radiotherapy presents additional complexity due to poor tissue quality. The impact on urinary and sexual function varies by etiology and must be considered when choosing a treatment approach. The management of PUS must consider the precise location and etiology of the stenosis. Treatment options vary from endoluminal techniques to open or robot-assisted reconstructions, chosen based on the patient's goals and overall health condition. Special attention must be given to the potential impact on urinary and sexual function. Les sténoses de l’urètre postérieur (SUP) constituent un défi chirurgical. Cet article vise à synthétiser les connaissances actuelles sur la prise en charge des SUP. Une revue exhaustive de la littérature a été effectuée en utilisant la base de données PubMed pour entre 2020 et 2023. Les recommandations de l’AUA, de l’EAU, de la CUA et plusieurs ouvrages de référence ont été utilisés pour compléter cette revue. Une synthèse par étiologie a été réalisée. Les SUP post-traumatique du bassin représentent une complication fréquente des fractures pelviennes. Les traitements sont bien codifiés : réalignement précoce, urétroplastie/résection-anastomose. Les sténoses post-traitement de l’hypertrophie bénigne de prostate, posent des défis particuliers en raison du risque élevé d’incontinence urinaire. La gestion des sténoses postprostatectomie radicale dépend de la localisation et peut inclure des traitements endoscopiques ou des reconstructions complexes. Les sténoses post-traitement physique présentent une complexité supplémentaire due à la faible qualité des tissus. L’impact sur la fonction urinaire et sexuelle varie en fonction de l’étiologie et doit être impérativement pris en compte dans le choix du traitement. La prise en charge d’une SUP doit tenir compte de la localisation exacte de la sténose et de son étiologie. Les options thérapeutiques vont des techniques endoluminales aux reconstructions ouvertes ou robot-assistées, choisies en fonction des objectifs du patient et de son état de santé général. Il faudra avoir une attention particulière aux impacts fonctionnels sur les fonctions urinaire et sexuelle.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
