[Outcomes of early endoscopic realignment of post-traumatic posterior urethral ruptures]. / Résultats du réalignement endoscopique précoce des ruptures de l'urètre postérieur post-traumatique.

INTRODUCTION: Post-traumatic rupture of the posterior urethra is a serious injury that can compromise the micturition and erectile prognosis of the often-young patient. The management of this lesion is still controversial, leaving the choice between early endoscopic realignment or suprapubic catheterization with deferred urethroplasty. The objective of this study was to report our clinical experience and outcomes with early endoscopic realignment (EER) for patients with pelvic fracture urethral injury. PATIENTS AND METHODS: We underwent a retrospective review of patients with pelvic fracture associated urethral injury who underwent EER from 2010 to 2020. Preoperative, perioperative, and postoperative outcome data were collected. Complications for the surgical procedure were analyzed, as well as postoperative stenosis, urinary incontinence and erectile dysfunction. The primary endpoint was success, defined as satisfying micturition with no urethral stricture at the time of last follow-up. RESULTS: Early endoscopic realignment was performed in 26 patients managed for complete post-traumatic posterior urethral rupture. The median age was 26 (16-39) years. The most common mechanism of urethral injury was road traffic accidents in 69.23% of cases. The most common urethral injury was grade 4 in 23 patients (88.46%). The median time to endoscopic realignment was 8 days (3-18). The median time to postoperative bladder catheterization was 22 (10-32) days. The median follow-up time was 34 (18-54) months. Ten patients developed urethral stricture during follow-up: 7 (26.92%) were treated with one or two internal cold blade urethrotomies, 3 required urethroplasty. There were no urethroplasty failures after a first endoscopic realignment. Two patients reported severe stress urinary incontinence. The median IIEF-5 score at the date of last news was 23 (17-25). CONCLUSION: Early endoscopic realignment allows some patients to avoid a heavier surgical treatment, and doesn't compromise the realization of a later urethroplasty.

Hematuria macroscópica como signo inicial del cáncer primario de uretra. Reporte de caso / Macroscopic hematuria as an initial sign of primary urethral cancer. Case report

Fundamento: El cáncer primario de uretra se define como el tumor cuya primera lesión se localiza en la uretra; es infrecuente, el mismo representa menos del 1 % de los tumores malignos y el 5 % de los tumores malignos del sistema urinario. La extensión de este proceso a la glándula prostática genera sintomatología urinaria obstructiva e irritativa y cuadros agudos como la hematuria macroscópica. Objetivo: Presentar el caso de un paciente con cáncer primario de uretra en su variedad urotelial con hematuria macroscópica como forma clínica de presentación. Presentación del caso: Caso clínico de un paciente masculino de 75 años de edad, con hematuria macroscópica como forma clínica de presentación de cáncer primario de uretra en su variedad urotelial, el cual se diagnosticó anatomopatológicamente durante el estudio de la hematuria. Conclusiones: El caso que se presenta permite alertar a la comunidad científica que en pacientes que presentan hematuria macroscópica, sin manifestaciones urológicas obstructivas ni irritativas, también debe tenerse en cuenta el diagnóstico de cáncer uretral primario, aunque sea un signo infrecuente como forma clínica de presentación de esa enfermedad.

Background: Primary urethral cancer is defined as a tumor whose first lesion is located in the urethra; is very uncommon, represents less than 1% of malignant tumors and 5% of malignant tumors of the urinary system. The extension of this process to the prostate gland creates obstructive and irritative urinary symptoms and acute conditions such as macroscopic hematuria. Objective: To present the case of a patient with primary urethral carcinoma in its urothelial variety with macroscopic hematuria as clinical presentation. Case presentation: Clinical case of a 75-year-old male patient, with macroscopic hematuria as a clinical presentation of primary cancer of the urethra in its urothelial variety, diagnosed anatomopathologically during the hematuria study. Conclusions: The case presented alerts the scientific community that the diagnosis of primary urethral cancer should be considered in patients with macroscopic hematuria in the absence of obstructive or irritative urologic manifestations, although it is a rare sign as clinical presentation of this disease.

Buccal mucosa graft urethroplasty for bulbar urethral stricture: Outcomes andpredictive factors affecting success.

INTRODUCTION AND OBJECTIVE: The bulbar urethra is the location where urethral stricture is most commonly observed. The most successful method for long and recurrent urethral stenosis is graft urethroplasty. The most successful graft source is buccal mucosa, with advantages like easy adaptation to the corporeal bed, thick epithelium, thin lamina propria with rich vascular structure and easy ability to obtain the graft. In this study we aimed to retrospectively assess the outcomes and predictive factors affecting surgical success of our buccal mucosal graft urethroplasty surgery performed for bulbar urethra stenosis with moderate length. MATERIAL AND METHOD: In this study, we monitored 51 patients with mean 4.4 cm bulbar urethral stricture length for mean 17 months follow-up. From operative and postoperative data, stenosis length, operation duration, Qmax, International Prostate Symptom Score, International Index of Erectile Function-Erectile Function and OF, success rates in total and in subgroups (age, according to DVIU, etiology, BMI and DM), follow-up duration, complications, re-stricture time and number were assessed. RESULTS: The total success of the operations was 86.3%. In 17 months, the re-stricture rate was 13.7%. Oral and urethral complications were all minor. The complications with longest duration (6 months) were ejaculation, erection problems and urethral fistula. Mean time to re-stricture was 11 months. All re-stricture patients were relieved by one DVIU session each. CONCLUSION: For bulbar urethral stricture longer than 2 cm and with recurrence, the dorsal buccal mucosa graft replacement is a very successful method with low complication rates.

Uretroplastia con injerto de mucosa oral para la estenosis de uretra bulbar: resultados y factores predictivos asociados al éxito / Buccal mucosa graft urethroplasty for bulbar urethral stricture: Outcomes and predictive factors affecting success

Introducción y objetivo La uretra bulbar es la localización en la que se observa con más frecuencia la estenosis uretral. La técnica con mayores tasas de éxito para el tratamiento de estenosis largas y recurrentes que facetan la uretra es la uretroplastia con injerto. La procedencia del injerto que ha mostrado resultados más satisfactorios es la mucosa oral, por sus beneficios como la fácil adaptación al lecho de cuerpos cavernosos, un epitelio grueso, una lámina propia fina con una estructura vascular rica, además de ser fácil de obtener. En este estudio nos propusimos evaluar retrospectivamente los resultados de nuestra cirugía de uretroplastia con injerto de mucosa oral realizada para la estenosis de uretra bulbar con longitud moderada y los factores predictivos asociados al éxito quirúrgico. Material y métodos En este estudio se evaluó a 51 pacientes con una longitud media de 4,4cm de estenosis de uretra bulbar durante una media de 17 meses de seguimiento. A partir de los datos operatorios y postoperatorios, se evaluó la longitud de la estenosis, el tiempo quirúrgico, el Qmáx, el International Prostate Symptom Score, el International Index of Erectile Function-Erectile Function y la OF, las tasas de éxito globales y por subgrupos (edad, según sesiones de UIVD, etiología, índice de masa corporal y diabetes mellitus [DM]), la duración del seguimiento, las complicaciones, el tiempo y el número de reestenosis. Resultados El éxito global de las intervenciones fue del 86,3%. En 17 meses, la tasa de reestenosis fue del 13,7%. Las complicaciones orales y uretrales fueron todas menores. Las complicaciones de mayor duración (6 meses) fueron los trastornos de eyaculación y erección y la fístula uretral. El tiempo medio de reestenosis fue de 11 meses. Todos los pacientes con reestenosis se resolvieron con una sesión de UIVD cada uno (AU)

Dilataciones uretrales: un clásico vigente. Caso clínico / Urethral dilations: a traditional treatment still in use. Clinical case

Se presenta el caso de un varón de 76 años de edad diagnosticado de estenosis uretral hace 20 años. El paciente es tratado en la Unidad Enfermera Urológica mediante dilataciones uretrales periódicas. El tratamiento mediante dilataciones de las estenosis uretrales es muy antiguo. Durante años fue el único tratamiento disponible. Posteriormente las intervenciones quirúrgicas se han incorporado como tratamiento curativo. No obstante, las Dilataciones Uretrales han pasado a formar parte, como tratamiento alternativo, realizándose por parte de la Enfermera Urológica. Actualmente nuestro paciente prefiere seguir siendo tratado con las Dilataciones, y no con cirugía, pues, aunque la uroflujometría dista de ser excelente, su calidad de vida si lo es. (AU)

I am presenting a clinical case regarding a male patient who was diagnosed with urethral stricture twenty years ago. The patient receives treatment in the Urological Infirmary by way of urethral dilations. This method of treatment for urethral strictures is very old and for years it was the only one available. Surgical interventions have since been adopted as a remedial treatment. However, urethral dilations are still used as an alternative treatment at the Urological Infirmary. At present, our patient prefers to continue being treated with the dilations instead of surgery, and while his uroflowmetry is far from excellent, his quality of life is good. (AU)

Los fenómenos pop-off como factores protectoresde enfermedad renal crónica en niños con válvulasde uretra posterior / Pop-off mechanisms as protective factors against chronic renal disease in children with posterior urethral valves

Objetivos: Identificar si los fenómenos pop-off actúan como factoresprotectores de enfermedad renal crónica o terminal en pacientes conválvulas de uretra posterior. Material y métodos: Estudio de cohortes retrospectivo de los pa-cientes con válvulas de uretra posterior tratados en un hospital infantil detercer nivel. Se recogieron variables demográficas, clínicas, analíticas yradiológicas. Se consideraron fenómenos pop-off: reflujo vesicoureteralde alto grado unilateral con displasia renal ipsilateral y sin afectación delriñón contralateral, urinoma, ascitis urinaria prenatal, divertículo vesicalgrande y uraco persistente. Para el análisis estadístico se han utilizadoregresiones logísticas múltiples y regresión de Cox multivariante. Resultados: Se incluyeron 70 pacientes intervenidos de válvulas deuretra posterior y visitados en nuestro centro desde 2010 hasta agostode 2020. Catorce (20%) presentaban fenómenos pop-off y 56 (80%)no. Los fenómenos pop-off fueron protectores para el desarrollo deenfermedad renal crónica (0 vs. 27%; p = 0,03) y podrían proteger de lanecesidad de terapia renal sustitutiva (0 vs. 9%; p = 0,58). Los valores decreatinina nadir (mg/dl) fueron predictores de desarrollo de enfermedadrenal crónica (0,37 vs. 0,53; p < 0,0001) y de necesidad de terapia renalsustitutiva (0,38 vs. 1,21; p < 0,001). Conclusiones: Los fenómenos pop-off actúan como factor protectorde enfermedad renal crónica en los pacientes con válvulas de uretraposterior. La creatinina nadir es un factor predictor de enfermedad renalcrónica y de necesidad de terapia renal sustitutiva. Se necesita un tamañode muestra mayor para determinar si los fenómenos pop-off protegende la necesidad de terapia renal sustitutiva.(AU)

Objective: To identify whether pop-off mechanisms act as protec-tive factors against chronic or end-stage renal disease in patients withposterior urethral valves. Materials and methods: A retrospective cohort study of patients withposterior urethral valves treated at a tertiary care children’s hospital wascarried out. Demographic, clinical, analytical, and radiological variableswere collected. Considered as pop-off mechanisms were: unilateral high-grade vesicoureteral reflux with ipsilateral renal dysplasia and withoutinvolvement of the contralateral kidney, urinoma, prenatal urinary ascites,large bladder diverticulum, and persistent urachus. Multiple logistic regres-sion and multivariate Cox regression were used for statistical analysis. Results: 70 patients undergoing posterior urethral valve surgery inour institution from 2010 to August 2020 were included. 14 (20%) hadpop-off mechanisms and 56 (80%) did not. Pop-off mechanisms pro-tected against developing chronic renal disease (0% vs. 27%; p = 0.03)and could protect against the need for renal replacement therapy (0%vs. 9%; p = 0.58). Nadir creatinine values (mg/dl) were predictors forthe development of chronic renal disease (0.37 vs. 0.53; p < 0.0001)and the need for renal replacement therapy (0.38 vs. 1.21; p < 0.001). Conclusions: Pop-off mechanisms act as a protective factor againstchronic renal disease in patients with posterior urethral valves. Nadircreatinine is a predictor of chronic renal disease and the need for renalreplacement therapy. A larger sample size is needed to determine whetherpop-off mechanisms protect against the need for renal replacement therapy.(AU)

Tomografía computarizada con reconstrucción 3D para el diagnóstico de lesiones traumáticas de uretra / Three-dimensional computed tomography reconstruction for the diagnosis of traumatic urethral injuries

RESUMEN La uretrografía retrógrada es la técnica de referencia (gold standard) utilizada clásicamente para hacer diagnóstico de lesiones de uretra. En este contexto se presenta un caso en el que se realizó tomografía computarizada con reconstrucción 3D con contraste intravenoso y endouretral, pudiendo reconstruir la uretra en toda su extensión en forma tridimensional. De esta manera se arribó al diagnóstico de certeza de la lesión de uretra. Como ventaja del método se menciona la posibilidad de diagnosticar ‒ con un solo estudio por imágenes‒ lesiones de todo el tracto urinario, órganos sólidos, huecos y lesión del anillo pélvico asociados al traumatismo, con una alta sensibilidad y especificidad sin necesidad de requerir otros estudios complementarios.

ABSTRACT Retrograde urethrography is the gold standard method for the diagnosis of urethral injuries. In this setting, we report the use of computed tomography with intravenous injection and urethral administration of contrast medium and 3D reconstruction of the entire urethra. The definitive diagnosis of urethral injury was made. The advantage of this method is the possibility of making the diagnosis of traumatic injuries of the entire urinary tract, solid organs, hollow viscera and of the pelvic ring within a single imaging test, with high sensitivity and specificity, with no need to perform other complementary tests.

Ressecção endoscópica de extensa lesão condilomatosa uretral ­ relato de caso e revisão da literatura / Endoscopic resection of extensive urethal condilomatic injury - case report and literature review

Introdução: O Condiloma uretral é uma infecção sexualmente transmissível comum associada ao vírus do papiloma humano. O acometimento na uretra é raro, principalmente quando trata-se de um paciente HIV positivo com carga viral indetectável. Objetivo: Tem como objetivo discutir sobre o acometimento uretral do papiloma vírus e as possíveis formas de tratamento, assim como revisar a literatura. Relato de caso: O paciente em questão apresentou suspeita de carcinoma de células de transição, sendo encaminhado para tratamento, porém afastado essa suspeita e fechando diagnóstico para lesão condilomatosa uretral, sendo realizado tratamento por ressecção endoscópica das lesões com energia monopolar. Discussão: O acometimento uretral ocorre em até 5% dos casos, e o mesmo apresenta alta probabilidade de malignização. Não existem diretrizes específicas sobre o manejo do condiloma intra-uretral, pois trata-se de uma patologia rara. O objetivo dos tratamentos é remover as verrugas e induzir períodos livre de lesões, sendo que o conservador com crioterapia e o ácido tricloroacético nem sempre são aplicáveis à uretra devido ao difícil acesso. A ressecção endoscópica das lesões tem se mostrado mais eficaz. Conclusão: Urologistas e patologistas devem estar cientes dessa rara possibilidade, a fim de evitar erros de diagnóstico acerca dessa entidade predominantemente benigna. Desta forma apresentamos um caso de ressecção endoscópica de extensa lesão condilomatosa em uretra peniana de uma paciente masculino hemofílico e HIV positivo. [au]

Introduction: Urethral condyloma is a common sexually transmitted infection associated with the human papillomavirus (HPV). Affection in the urethra is rare, especially when dealing with an HIV positive patient with an undetectable viral load. Objective: It aims to discuss the urethral involvement of the papillomavirus and the possible forms of treatment, as well as to review the literature. Case report: The patient in question presented suspicion of transitional cell carcinoma, being referred for treatment, but this suspicion was removed and the diagnosis of urethral condylomatous lesion was closed, with treatment by endoscopic resection of the lesions with monopolar energy. Discussion: Urethral involvement occurs in up to 5% of cases, and it has a high probability of malignancy. There are no specific guidelines on the management of intra-urethral condyloma, as it is a rare condition. The goal of treatments is to remove warts and induce injury-free periods, the conservative with cryotherapy and trichloroacetic acid not always being applicable to the urethra due to difficult access. Endoscopic resection of the lesions has been shown to be more effective. Conclusion: urologists and pathologists should be aware of this rare possibility, in order to avoid diagnostic errors about this predominantly benign entity. Thus, we present a case of endoscopic resection of an extensive condylomatous lesion in the penile urethra of a male patient with hemophilia and HIV positive. [au]

First Case Described in the Medical Literature: Male Urethral Sarcoidosis. Description of a Case and Review of the Literature

Objective: Although the sarcoidosis is a multisystemic disease that theoretically can affect almost any organ, the presence of sarcoidosis in the male urethra has not been described in the medical literature. We present the first male case of urethral sarcoidosis. Method: A 46 years old male undergoing follow up due to lower urinary tract symptoms was diagnosed of endobronchial sarcoidosis during the preoperative study for internal urethrotomy. After surgery, he presented clinical improvement for one year. Given the worsening, a new internal urethrotomy was tried. As it was impossible due to complexity they took a biopsy of the urethra. The pathology report described non-caseating granulomas compatible with sarcoidosis. After that, medical and endoscopic management of the urethral sarcoidosis was attempted. As it didn't achieve an adequate control, the patient was derivate to the "complex urethral unit" of the Cruces University Hospital. Once it was valuated, it was decided to start immunotherapy and subsequently an urethroplasty with a double oral mucosa graft was performed. Outcomes: During the postoperative period, a urethral catheter was maintained for two weeks. It was removed after no urinary leakage was observed in de cystourethrography. After that the patient remains with good evolution until today. Conclusions: Urethral affectation by sarcoidosis is a therapeutic challenge itself. For a better symptom control and to reduce the recurrences, a dual approach using systemic treatment in combination with local surgical treatment seems necessary (AU)

Objetivo: Pese a que la sarcoidosis es una enfermedad multisistémica que teóricamente puede afectar a casicualquier órgano, no ha sido descrita en la literatura médicala presencia de sarcoidosis en uretra masculina. Presentamos el diagnóstico y tratamiento del primer caso masculinode sarcoidosis uretral.Método: Varón de 46 años en seguimiento por clínicamiccional de vaciado al que se le diagnosticó de sarcoidosis endobronquial durante el estudio preoperatorio para larealización de una uretrotomía interna. Tras la intervenciónpresentó mejoría clínica durante un año. Ante el empeoramiento, se intentó repetir una nueva uretrotomía internasiendo esta imposible y decidiéndose realizar una biopsia.El informe anatomopatológico describió granulomas no caseificantes compatibles con sarcoidosis. Posteriormente seintentó un manejo médico y endoscópico de la sarcoidosis uretral que no logró un adecuado control por lo que sederivó a la unidad de uretra compleja del Hospital Universitario Cruces. Ante los hallazgos se decidió comenzar coninmunoterapia y posteriormente se realizó una uretroplastiacon doble injerto de mucosa oral.Resultado: Durante el postoperatorio se mantuvo unasonda uretral durante dos semanas. Posteriormente se retirótras la realización de una cistouretrografía miccional seriada donde no se apreciaba fuga urinaria permaneciendo elpaciente con buena evolución hasta hoy en día.Conclusiones: La afectación uretral por sarcoidosissupone actuar ante una patología que de por sí es un retoterapéutico. Para un mejor control sintomatológico y reducir las recidivas parece necesario un abordaje doble mediante un tratamiento sistémico farmacológico en combinación con tratamiento quirúrgico local (AU)

la incontinencia urinaria (IU), se define por la Sociedad Internacional de Continencia, como la perdida involuntaria de orina, una condición potencialmente tratable con disminución de la calidad de vida de las mujeres en diferentes aspectos, entre ellos la salud sexual con su pareja y su bienestar social. Se han descrito que solo el 44,9 % de las mujeres consultan, teniendo mayores tasas de depresión y ansiedad. El objetivo de esta investigación fue determinar la aparición de complicaciones intraoperatorias y posoperatorias con la realización de cintas transobturadora y retropúbica en el Hospital Militar Central en Bogotá durante el periodo 2015 al 2020. Se realizó un estudio observacional, descriptivo, retrospectivo de corte longitudinal, en el Hospital Militar Central en Bogotá; se incluyeron todas las pacientes con diagnósticos de incontinencia urinaria, tanto de esfuerzo, como de urgencias y/o mixtas, intervenidas con cintas medios uretrales libres de tensión por vía retropúbica o transobturadora. Las complicaciones posteriores al procedimiento quirúrgico la más prevalente fue el dolor con un 96,8 %, seguida de infección urinaria o expulsión de la banda con un 8,6 %; entre otras complicaciones menos frecuentes como hematomas, dispareunia y abscesos. La mayoría de las pacientes obtuvieron una adecuada respuesta clínica en el postoperatorio, el 77 % no requirió ningún manejo adicional. Las cintas mediouretrales, proporcionan un buen resultado con una baja incidencia de complicaciones quirúrgicas y recidiva, con mejoría de la calidad de vida de la paciente frente a su patología de incontinencia urinaria.

The International Continence Society defines urinary incontinence (UI) as the involuntary loss of urine, a potentially treatable condition with a decrease in the quality of life of women in different aspects, including sexual health with their partner and their social well-being. It has been described that only 44.9% of women consult, having higher rates of depression and anxiety. The objective of this research was to determine the occurrence of intraoperative and postoperative complications with the performance of transobturator and retropubic taping at the Central Military Hospital in Bogota during the period 2015 to 2020. An observational, descriptive, retrospective, retrospective. All patients with diagnoses of urinary incontinence, both stress, emergency, and/or mixed, operated with tension-free mid-urethral tapes by retropubic or transobturator route were included. The most prevalent complications after the surgical procedure were pain (96.8 %), followed by urinary tract infection or expulsion of the band (8.6 %), among other less frequent complications such as hematomas, dyspareunia, and abscesses. Most patients obtained an adequate clinical response in the postoperative period, 77 % did not require additional management. Mediourethral tapes provide a good result with a low incidence of surgical complications and recurrence, improving the patient's quality of life concerning her urinary incontinence pathology.

As complicações mais prevalentes após o procedimento cirúrgico foram dor (96,8%), seguida de infecção do trato urinário ou expulsão da faixa (8,6%), entre outras complicações menos frequentes, como hematomas, dispareunia e abscessos. A maioria dos pacientes teve uma resposta clínica adequada no pós-operatório e 77% não precisaram de nenhum tratamento adicional. Os slings mediouretrais proporcionam um bom resultado com baixa incidência de complicações cirúrgicas e recorrência, com melhora na qualidade de vida da paciente com relação à sua patologia de incontinência urinária.

Urethral leiomyoma: combined vaginal and abdominal approach - a case report / Mioma uretral: abordagem combinada vaginal e abdominal - um relato de caso

Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.

Resumo Introdução: os leiomiomas são tumores mesenquimais benignos de origem muscular lisa, podendo manifestar-se em diversas localizações. Os leiomiomas uretrais são raros, tendo apenas aproximadamente 120 casos relatados na literatura. São mais comuns na terceira e quarta décadas de vida, sendo raros em pacientes menopausadas. Em geral, são tratados cirurgicamente, com apenas três relatos de recidivas na literatura. Descrição: relato de caso de uma paciente do sexo feminino, 56 anos, portadora de diabetes mellitus do tipo II, hipertensão arterial crônica, sobrepeso (IMC 27,1Kg/m2) e tabagismo. Além disso, com quadro de sintomas obstrutivos urinários e portadora de um grande leiomioma uretral, este que foi completamente removido, através de uma desafiadora abordagem cirúrgica combinada (abdominal e vaginal), sem lesões uretrais associadas. Discussão: os leiomiomas uretrais são tumores raros e seu manejo é desafiador e ainda não foi estabelecido.

Uretroplastia término terminal y reconstrucción cavernosa temprana en ruptura bilateral de origen traumático / End-to-End Urethroplasty and Early Cavernous Reconstruction in Bilateral Rupture of Traumatic Origin / Uretroplastia término-terminal e reconstrução cavernosa precoce em rotura bilateral de origem traumática

Introducción. La fractura de pene es una emergencia urológica rara, se desconoce la incidencia real dado el subregistro causado por la reducida consulta de los pacientes, resultado del embarazoso contexto. En Estados Unidos alcanza un 38% donde la etiología de índole sexual predomina. En Colombia hay escasos reportes publicados. El diagnóstico de esta entidad es netamente clínico. El objetivo de este trabajo es reportar una evolución satisfactoria en términos de función miccional y eréctil en un paciente sometido a reconstrucción cavernosa y uretral temprana en rotura bilateral de origen traumático mediante una técnica quirúrgica poco convencional, de acuerdo con lo hallado en la literatura. Presentación del caso. Paciente masculino de 30 años, previamente sano, quien consultó al servicio de urgencias por uretrorragia, edema y dolor peneano secundario a trauma contuso del mismo durante relación sexual. El reporte ecográfico mostró disrupción en túnica albugínea del cuerpo esponjoso, hematoma y aparente transección uretral; se realizó exploración quirúrgica 6 horas después, con evidencia de fractura de cuerpos cavernosos, laceración del 40% de la circunferencia, transección completa de la uretra y cuerpo esponjoso. Se realizó rafia de cuerpos cavernosos y uretroplastia término terminal de uretra bulbar, con evolución clínica satisfactoria. Discusión. La reconstrucción quirúrgica en menos de 24 horas en fractura de pene disminuye significativamente la estancia hospitalaria y complicaciones precoces; asimismo, desciende el riesgo de disfunción eréctil, erecciones dolorosas y problemas miccionales. No hay publicaciones que comparen resultados a largo plazo entre los dos abordajes quirúrgicos. Conclusiones. La fractura de pene es una patología poco frecuente con diagnóstico clínico, la cual debe manejarse de manera temprana por cualquier urólogo y, en caso de ser posible, con experiencia reconstructiva y excelentes resultados en la función sexual y miccional.

Introduction. Penile fracture is a rare urological emergency, the real incidence is unknown given the underreporting caused by the reduced consultation of patients, resulting from the embarrassing context. In the United States it reaches 38%, where sexual etiology predominates. In Colombia there are few published reports. The diagnosis of this entity is purely clinical. The aim of this work is to report a satisfactory evolution in terms of voiding and erectile function in a patient who underwent early cavernous and urethral reconstruction in bilateral rupture of traumatic origin by means of an unconventional surgical technique, in accordance with what has been found in the literature. Case Presentation. A 30-year-old male patient, previously healthy, consulted the emergency department for urethrorrhagia, edema and penile pain secondary to blunt trauma to the penis during sexual intercourse. The ultrasound report showed disruption in the tunica albuginea of the corpus spongiosum, hematoma and apparent urethral transection; surgical exploration was performed 6 hours later, with evidence of fracture of the corpora cavernosa, laceration of 40% of the circumference, complete transection of the urethra and corpus spongiosum. Sutures to the corpora cavernosa and end-to-end urethroplasty of the bulbar urethra were performed, with satisfactory clinical evolution. Discussion. Surgical reconstruction in less than 24 hours in penile fractures significantly reduces hospital stay and early complications; it also reduces the risk of erectile dysfunction, painful erections and voiding problems. There are no publications comparing long-term results between the two surgical approaches. Conclusions. Penile fracture is a rare pathology with clinical diagnosis, which should be managed early by any urologist and, if possible, with reconstructive experience and excellent results in sexual and voiding function.

Introdução. A fratura peniana é uma emergência urológica rara, a real incidência é desconhecida dada a subnotificação causada pela reduzida consulta de pacientes, resultado do contexto constrangedor. Nos Estados Unidos chega a 38% onde predomina a etiologia de natureza sexual. Na Colômbia há poucos relatórios publicados. O diagnóstico desta entidade é puramente clínico. O objetivo deste trabalho é relatar uma evolução satisfatória da função miccional e erétil em um paciente submetido à reconstrução cavernosa e uretral precoce em ruptura bilateral de origem traumática por meio de técnica cirúrgica não convencional, de acordo com o que foi encontrado na literatura. Apresentação do caso. Paciente do sexo masculino, 30 anos, previamente saudável, procurou o pronto-socorro por uretrorragia, edema e dor peniana secundária a trauma contuso durante a relação sexual. O relatório do ultrassom mostrou ruptura na túnica albugínea do corpo esponjoso, hematoma e transecção uretral aparente; a exploração cirúrgica foi realizada 6 horas depois, com evidência de fratura dos corpos cavernosos, laceração de 40% da circunferência, transecção completa da uretra e corpo esponjoso. Foram realizadas ráfia dos corpos cavernosos e uretroplastia término-terminal da uretra bulbar, com evolução clínica satisfatória. Discussão. A reconstrução cirúrgica em menos de 24 horas nas fraturas penianas reduz significativamente o tempo de internação e as complicações precoces. Da mesma forma, diminui o risco de disfunção erétil, ereções dolorosas e problemas de micção. Não há publicações comparando os resultados a longo prazo entre as duas abordagens cirúrgicas. Conclusões. A fratura peniana é uma patologia rara com diagnóstico clínico, que deve ser tratada precocemente por qualquer urologista e, se possível, com experiência reconstrutiva e excelentes resultados na função sexual e miccional.

Consecuencias de la fractura de pene: complicaciones y resultados funcionales a largo plazo / Consequences of penile fracture: Complications and long-term functional outcomes

Introducción La fractura de pene (FP) es una urgencia urológica con baja incidencia, por lo que existe poca evidencia de los resultados a largo plazo. Este estudio se centra en las complicaciones postoperatorias y los resultados funcionales a largo plazo en pacientes que han sufrido una FP reparada quirúrgicamente en nuestro centro.Materiales y métodos Los registros clínicos de pacientes sometidos a cirugía urgente por FP en un hospital de tercer nivel entre 2006 y 2020 se revisaron retrospectivamente. Los resultados funcionales se evaluaron con visitas telefónicas voluntarias desde junio del 2020 a febrero del 2021. Se realizó un cribado de sintomatología del tracto urinario inferior mediante el cuestionario IPSS, de función sexual mediante el EHS y el IIEF-5, y de alteraciones morfológicas mediante pregunta directa a los pacientes.ResultadosCuarenta y un pacientes fueron sometidos a cirugía por FP; 11 de ellos además asociaron lesión uretral (mayor incidencia si había lesión de ambos cuerpos cavernosos, 19,4 vs. 80%, p<0,05). Solo un paciente presentó una complicación Clavien-Dindo tipo 3a por dehiscencia de la herida, 4 (13%) tipo 2 y 9 (29%) tipo 1. Realizaron seguimiento a largo plazo 24 pacientes, de los cuales 20 (83,3%) presentaban una función sexual normal. Doce (50%) presentaban un nódulo palpable en la zona de la fractura, 8 (33,3%) curvatura peneana de nueva aparición y un paciente con lesión uretral previa presentó estenosis de uretra.Conclusión En la fractura de pene, hay más incidencia de lesión uretral si se afectan ambos cuerpos cavernosos. Las secuelas funcionales a largo plazo tras la reparación quirúrgica de una FP son poco frecuentes (AU)

Consequences of penile fracture: Complications and long-term functional outcomes.

INTRODUCTION: Penile fracture (PF) is a urological emergency with low incidence, and evidence of its long-term outcomes is scarce. This study focuses on postoperative complications and long-term functional outcomes in patients with PF and surgical repair at our center. MATERIALS AND METHOD: Clinical records of patients undergoing urgent surgery for PF at a third level hospital between 2006 and 2020 were retrospectively reviewed. Functional outcomes were assessed with voluntary telephone interviews from June 2020 to February 2021. Lower urinary tract symptoms were screened by IPSS questionnaire, sexual function by EHS and IIEF-5 and morphological alterations by direct questions to patients. RESULTS: A total of 41 patients underwent surgery for PF. Eleven of them also had urethral injury (higher incidence if there was bilateral corpora cavernosa injury, 19.4% vs. 80%, p < 0.05). Only 1 patient presented a Clavien-Dindo type 3a complication due to wound dehiscence, 4 (13%) type 2 and 9 (29%) type 1. Twenty-four patients underwent long-term follow-up, of whom 20 (83.3%) presented normal sexual function. Twelve patients (50%) had a palpable nodule at the fracture site, 8 (33.3%) had new onset penile curvature and 1 patient with previous urethral injury presented urethral stricture. CONCLUSION: In cases of penile fracture, there is a higher incidence of urethral injury if both corpora cavernosa are affected. Long-term functional sequelae after surgical repair of a PF are rare.

Important interaction between urethral taste bud-like structures and Onuf's nucleus following spinal subarachnoid hemorrhage: A hypothesis for the mechanism of dysorgasmia / Interacción importante entre las estructras de tipo papila gustativa de la uretra y el núcleo de Onuf tras hemorragia subaracnoidea espinal: una hipótesis para el mecanismo de la disorgasmia

Background: We previously postulated that orgasmic sensation may occur through recently discovered genital taste bud-like structures. The interaction between the pudendal nerve and Onuf's nucleus may be important for developing orgasmic information. The study aims to investigate whether ischemic damage to Onuf's nucleus-pudendal network following spinal subarachnoid hemorrhage (SAH) causes taste bud degeneration or not.Methods: The study was conducted on 22 fertile male rabbits who were divided into three groups: control (GI; n=5), SHAM (GII; n=5) and study (GIII; n=12). Isotonic solution, .7cm3, for the SHAM, and .7cm3 homologous blood was injected into spinal subarachnoid spaces at S2 level of the study group. Two weeks later, Onuf's nucleus, pudendal ganglia and the taste bud-like structures of the penile urethra were examined histopathologically. Degenerated neuron densities of Onuf's nucleus, pudendal ganglia and atrophic taste bud-like structures were estimated per mm3 and the results analyzed statistically.Results: The mean degenerated neuron densities of taste bud-like structures, Onuf's nucleus and pudendal ganglia were estimated as 2±1/mm3, 5±1/mm3, 6±2/mm3 in GI; 12±4/mm3, 35±9/mm3, 188±31/mm3, in GII and 41±8/mm3, 215±37/mm3, 1321±78/mm3, in GIII. Spinal SAH induced neurodegeneration in Onuf's nucleus, pudendal ganglia and taste bud atrophy was significantly different between GI/GII (p<.005); GII/GIII (p<.0005) and GI/GIII (p<.0001). (AU)

Antecedentes: Hemos postulado previamente que la sensación orgásmica puede producirse a través de las recientemente descubiertas estructuras de tipo papila gustativa de los genitales. La interacción entre el nervio pudendo y el núcleo de Onuf puede ser importante para desarrollar información orgásmica. El objetivo del estudio fue estudiar si el daño isquémico a la red núcleo-ganglios pudendos de Onuf tras una hemorragia subaracnoidea espinal (HSA) puede causar o no una degeneración de las estructuras de tipo papila gustativa.Métodos: El estudio fue realizado en 22 conejos fértiles que se dividieron en 3 grupos: control (GI; n=5), placebo (GII; n=5) y de etudio (GIII; n=12). Se inyectaron 0,7cc de solución isotónica a los miembros del grupo placebo, y 0,7cc de sangre homóloga en los espacios subaracnoideos espinales a nivel de S2, al grupo de estudio. Al cabo de 2 semanas se examinaron histopatológicamente el núcleo de Onuf, los ganglios pudendos y las estructuras de tipo papila gustativa de la uretra. Se calcularon por mm3 las densidades de las neuronas degeneradas del núcleo de Onuf, los ganglios pudendos y las estructuras atróficas de tipo papila gustativa, analizándose estadísticamente los resultados.Resultados: Las densidades medias de las neuronas degeneradas de las estructuras de tipo papila gustativa, el núcleo de Onuf y los ganglios pudendos se calcularon como 2±1, 5±1, 6±2/mm3 en GI; 12±4, 35±9, 188±31 en GII y 41±8, 215±37, 1321±78/mm3, en GIII. La neurodegeneración inducida de HSA en el núcleo de Onuf, los ganglios pudendos y la atrofia de las papilas gustativas fue significativamente diferente entre los grupos GI/GII (p<0,005); GII/GIII (p<0,0005) y GI/GIII (p<0,0001).

CONCLUSION: Ischemic neuronal degenerations of Onuf's nucleus and pudendal ganglia following spinal SAH lead to genital taste bud-like structure atrophy. This mechanism may be responsible for sexual anhedonia and sterility in cases with spinal cord injury, which has not been documented so far. More studies are needed.

Manejo quirúrgico de prolapso uretral en pediatría: Reporte de caso / Surgical management of urethral prolapse in pediatrics: A case report

Introducción. El prolapso uretral es una entidad poco común, con una incidencia estimada de 1 en 3000 mujeres. Se presenta cuando la mucosa uretral sobresale espontáneamente más allá del meato uretral. Es una patología poco diagnosticada dada su baja frecuencia y de allí la importancia de conocer sobre su presentación, diagnóstico y tratamiento. El objetivo de este artículo fue presentar el caso de una paciente de 10 años con diagnóstico de prolapso uretral y su manejo quirúrgico. Caso clínico. Paciente femenina de 10 años, que consultó por cuadro clínico de 1 año de evolución consistente en dolor en región urogenital, que se irradiaba a hipogastrio, asociado a pujo y disuria, a quien se le diagnosticó prolapso uretral y se realizó corrección quirúrgica de mucosa uretral prolapsada mediante técnica de Kelly-Burnham modificada. Conclusión. El prolapso uretral es una entidad que con frecuencia es diagnosticada erróneamente pues su diagnóstico es eminentemente clínico. Si bien se ha descrito el tratamiento médico en primera instancia, éste tiene una alta tasa de recurrencia, por lo que en estos casos se prefiere la resección quirúrgica del tejido prolapsado.

Introduction. Urethral prolapse is a rare entity, with an estimated incidence of 1 in 3,000 women. It occurs when the urethral mucosa spontaneously protrudes beyond the urethral meatus. It is a poorly diagnosed pathology given its low frequency and hence the importance of knowing about its presentation, diagnosis and treatment. The objective of this article was to present the case of a 10-year-old patient with a diagnosis of urethral prolapse and its surgical management. Clinical case. A 10-year-old female patient, who consulted for a 1-year clinical picture consisting of pain in the urogenital region, radiating to the hypogastrium, associated with pushing and dysuria, who was diagnosed with urethral prolapse and a surgical correction of the urethral mucosa was performed prolapsed by modified Kelly-Burnham technique. Conclusion. Urethral prolapse is an entity that is frequently misdiagnosed because its diagnosis is eminently clinical. Although medical treatment has been described in the first instance, it has a high recurrence rate, so surgical resection of the prolapsed tissue is preferred in these cases.

Predictores de cirugía uretral compleja en estenosis de la uretra anterior / Predictors of complex urethral surgery in urethral stricture former

Objetivo: Determinar los factores predic-tores asociados a Cirugía Uretral Compleja (CUC) enlos casos de estenosis de la uretra anterior.Material y método: Estudio transversal con registro de datos retrospectivo, incluye a todos los pacientes masculinos a quienes se les practicó una plastía dela uretra anterior entre 2011 y 2018. Como CUC seconsideró a la Uretroplastia con dos o más injertos, laanastomosis término terminal ampliada, la uretroplastíacombinada y la cirugía por estadíos. Los datos se recabaron de la historia clínica electrónica consignándoseaquellos demográficos, antecedente de tratamientosprevios, así como las características de la estenosis(etiología, ubicación anatómica, longitud, número deestenosis entre otras). Se realizó un análisis univariadoy multivariado para identificar variables predictoras deCUC. Resultados: Se analizaron los datos de 665 pacientes con criterios de inclusión válidos. La media de edadfue de 56,1 años, 27,5% eran fumadores crónicos,32,5% habían recibido algún tratamiento previo, siendolas dilataciones el procedimiento más común (17,6%),la etiología más prevalente fue la iatrógena seguida porla idiopática en un 61,1 y un 20,3% respectivamente,la ubicación más común fue la uretra bulbar en 56,2%mientras que la media de longitud de la estenosis fuede 4,8 cm. En el análisis univariado y multivariable elantecedente de dilataciones (HR 2,6), la multifocalidad(HR 2,51), la longitud de la estenosis (>4 cm) (HR 1,49)y la etiología hipospadias (HR 11,9) resultaron ser factores predictores independientes para CUC (p<0,05).Conclusiones: La hipospadia fue dentro de lasetiologías analizadas la única que predice la necesidad de CUC. En lo que respecta a antecedentes yhallazgos radiológicos, las dilataciones y las estenosisextensas y multifocales respectivamente fueron predictores de CUC.(AU)

Objective: To determine the clinical-sur-gical factors associated with Complex Urethral Surgery(CUC) in anterior urethral stenosis.Material and method: This is a cross-sectionalstudy with retrospective data recording, including allmale patients who underwent anterior urethroplasty between 2011 and 2018. CUC included two or moregrafts urethroplasty, excisional augmented anastomoticurethroplasty, combined flaps and grafts urethroplastyand stages surgery. The data were collected electronic medical record, recording the demographicdata, background of previous treatments as well as thecharacteristics of the stenosis (etiology, anatomical location, length, number of strictures, among others). A univariate and multivariate analysis were conducted usingthe chi-squared test and logistic regression to identify thevariables related to CUC.Results: The data of 665 patients met the inclusioncriteria were analyzed. The mean age was 56.1 years,27.5% were smokers, 32.5% had received some previous treatment, and dilatations were the most commonprocedure. The most prevalent etiology was iatrogenic,followed by idiopathic in a 61.1 and 20.3% respectively. Bulbar urethral stricture were the most commonlocation (56.2%) while the mean length of the stenosiswas 4.8 cm. After univariate and multivariate analysis,previous dilations (HR 2.6), multifocality (2.51), lengthof stenosis (>4 cm) (HR 1.49) and the hypospadias etiology (HR 11.9) were independent predictors for CUC(p<0.05).Conclusions: Hypospadias was the only etiologyfactor that predicts the need for CUC. Regarding radiological findings, extensive and multifocal stenosis, werepredictors of complex surgery. History of previous dilations were also predictors of CUC.from the
