RESUMO
PURPOSE: A step-based anastomotic urethroplasty is a standard technique for repairing the posterior urethra in patients with pelvic fracture urethral injury (PFUI). We aim to identify pre-operative factors, including results of conventional radiological imaging, for prediction of elaborated perineal or a combined abdominoperineal procedure. METHODS: Retrospective observational study on 114 consecutive patients undergoing urethroplasty for PFUI between January 2020 and December 2022 was conducted. Surgical procedures were categorized according to the Webster classification into two groups: steps 1-2 (group 1) and steps 3-4 or a combined abdominoperineal repair (group 2). Pre-operative pattern results of RGU/VCUG were categorized regarding the relation between the proximal urethral stump with the pubic symphysis: posterior urethral stump below (pattern 1) or above (pattern 2) the lower margin of the pubic symphysis. Patient demographics were assessed. Univariate and multivariate logistic regression analyses were utilized. RESULTS: Overall, 102 patients were enrolled in the study for data analysis. On the multivariate logistic regression analysis, the presence of erectile dysfunction (OR 4.5; p = 0.014), prior combined treatment (endoscopic and urethroplasty) (OR 6.4; p = 0.018) and RGU/VCUG pattern 2 (OR 66; p < 0.001) significantly increased the likelihood of the need of step 3 or higher. CONCLUSIONS: The need of step 3 or higher during urethroplasty for PFUI can be predicted pre-operatively with conventional imaging (RGU/VCUG). Patients with proximal urethral stump above the lower margin of pubic symphysis were about 66 times more likely to need step 3 or higher during urethroplasty.

Objetivo: Determinar la etiología actual y las características clínicas de la estrechez y estenosis de uretra masculina, en una institución de alta complejidad. Método: Estudio observacional, descriptivo de tipo transversal. Se recolectó información de 344 pacientes con estrechez o estenosis de uretra a los cuales se les realizó uretroplastia entre enero de 2011 y marzo de 2019. Para cada paciente se tuvo en cuenta la edad, la etiología, el sitio uretral comprometido, la longitud de la estrechez, procedimientos previos y la cirugía realizada. Resultados: La edad media fue 59,6 años (rango 14-90 años). La etiología más común fue la iatrogénica (68,1%), seguida de la inflamatoria (13,9%), idiopática (12,2%) y traumática (5,5%). De las causas iatrogénicas, el 39,2% fueron secundarias a instrumentación uretral, el 20,6% a cirugía endoscópica de próstata, el 4,3% poscirugía de hipospadias, un 2,3% otras y un 1,7% cirugía de próstata abierta. Al estratificar por edad, la etiología de la estrechez más común fue iatrogénica en los tres grupos etarios: en el grupo de 0-45 años con un 32,6%, en el grupo de 46-59 años con un 63,3% y en el grupo de mayores de 60 años con un 83,4%. Conclusión: La estrechez de uretra es una patología que cada vez se presenta con más frecuencia en la práctica urológica diaria, no es una enfermedad de los ancianos sino que involucra a todas las edades. Actualmente, la principal causa es la etiología iatrogénica, por lo cual estamos obligados a mejorar las estrategias de prevención
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
