RESUMEN

Resumo O cateter vesical de longa permanência pode ser indicado em situações clínicas, como nas doenças crônicas do sistema genitourinário ou neurológico. Além dos riscos de infecção, traumas e sangramentos, a permanência do cateter pode afetar dimensões psicoemocionais e socioeconômicas. Objetivamos compreender como a necessidade de uso do cateter urinário por um longo prazo afeta a autopercepção, as interrelações e o autocuidado deste paciente. Realizamos um estudo qualitativo, descritivo, a partir da entrevista de 17 pacientes, e aplicamos a análise temática e o pensamento complexo. Os diferentes prognósticos e as expectativas em relação ao cateter influenciaram a autopercepção, a adaptação, sua aceitação ou negação. A presença do cateter, seja como medida curativa ou para conforto, pode afetar a autoimagem e a sexualidade, gerar inseguranças e incertezas, que requerem compreensão da multidimensionalidade das situações, que sofrem interferências do meio pessoal, familiar e social, bem como da capacidade dos sistemas de saúde para o seu enfrentamento. Apesar dos desafios, a maioria dos participantes relatou disposição favorável para o autocuidado, seja para viabilizar retirada do cateter, ou para prevenir agravos em indicações vitalícias.

Abstract A long-term indwelling catheter may be indicated in clinical situations, such as chronic diseases of the genitourinary or neurological systems. In addition to the risks of infection, trauma, and bleeding, a catheter's permanence can affect psycho-emotional and socioeconomic dimensions. We aimed to understand how the need to use a long-term indwelling catheter affects this patient's self-perception, interrelationships, and self-care. We carried out a qualitative, descriptive study based on interviews with 17 patients, and applied thematic analysis and complex thinking. The different prognoses and expectations regarding the catheter influenced self-perception, adaptation, acceptance, or denial. The presence of a catheter, whether as a curative measure or for comfort, can affect self-image and sexuality, and generate insecurities and uncertainties, which require understanding the multidimensionality of situations that suffer interference from the personal, family, and social environment, as well as health systems' capacity to deal with it. Despite the challenges, the majority of participants reported a favorable disposition towards self-care, whether to enable catheter removal or to prevent injuries in lifelong indications.

RESUMEN

OBJECTIVE: To evaluate the relationship between heart failure (HF), chronic obstructive pulmonary disease (COPD), and smoking with the development of urethral stricture (US) by examining the patients who underwent transurethral prostate resection procedure, with and without the development of US in their follow-ups. METHODS: Among the patients who underwent transurethral resection of the prostate, 50 patients who developed US during their follow-ups formed group 1, while a total of 50 patients who did not develop US and were selected by lot formed group 2. The relationship between the patients' data on HF, COPD and smoking status and the development of US was investigated. RESULTS: The mean number of cigarettes smoked was statistically significantly high in the group with stricture (p = 0.007). Furthermore, pulmonary function test parameters of patients such as forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC were found to be statistically significantly higher in Group 2 (p < 0.001, p < 0.001, and p = 0.008, respectively). In the logistic regression analysis, being a smoker was found to be the strongest predictor (p = 0.032). CONCLUSION: Our study concluded that smoking, HF, and COPD significantly increase the risk of developing stricture after transurethral resection of the prostate.

OBJETIVO: Evaluar la relación de la insuficiencia cardiaca, la enfermedad pulmonar obstructiva crónica y el tabaquismo con el desarrollo de estenosis de uretra en pacientes sometidos a resección transuretral de próstata con y sin desarrollo de estenosis de uretra en su seguimiento. MÉTODO: Cincuenta pacientes que desarrollaron estenosis de uretra durante su seguimiento formaron el grupo 1, y 50 pacientes que no desarrollaron estenosis de uretra y fueron seleccionados por lote formaron el grupo 2. Se investigó la relación de los datos de los pacientes sobre insuficiencia cardiaca, enfermedad pulmonar obstructiva crónica y tabaquismo con el desarrollo de estenosis uretral. RESULTADOS: La media de cigarrillos fumados fue significativamente más alta en el grupo con estenosis (p = 0.007). Además, se encontró que los parámetros de las pruebas de función pulmonar de los pacientes, como FEV1, FVC y FEV1/FVC, eran significativamente más altos en el grupo 2 (p < 0.001, p < 0.001 y p = 0.008, respectivamente). CONCLUSIONES: El tabaquismo, la insuficiencia cardiaca y la enfermedad pulmonar obstructiva crónica aumentan significativamente el riesgo de desarrollar estenosis después de una resección transuretral de próstata.

RESUMEN

INTRODUCTION AND OBJECTIVES: Female urethral strictures are a rare condition that significantly impacts patients' quality of life. Patient-reported outcomes are crucial, yet data regarding sexual function and treatment satisfaction are scarce. We aimed to provide insights from a reconstructive referral center. PATIENTS AND METHODS: We conducted a retrospective analysis of women treated with ventral onlay one-stage buccal mucosa graft urethroplasty for urethral strictures between 2009-2023. We assessed objective (retreatment-free survival, ΔQmax) and subjective outcomes (validated patient-reported outcomes). RESULTS: Of 12 women, 83% and 17% had iatrogenic and idiopathic strictures, respectively. Median number of prior interventions was 6. Strictures were located meatal and mid-urethral in 25% and 75%, respectively, 22% had the bladder neck involved. Median graft length was 2 cm. At median follow-up of 66 months, 33% of patients underwent stricture retreatment, but only one case occurred within the first 2 years postoperatively. The median improvement in maximum flow rate (ΔQmax) was 10 ml/s. Median International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS) scores were 8 for filling symptoms, 6 for voiding symptoms, and 3 for incontinence symptoms. Median ICIQ-FLUTSsex score was 4. Higher scores indicate a higher symptom burden. Median ICIQ-Satisfaction outcome and satisfaction scores were 18 and 7, respectively, reflecting high treatment satisfaction. CONCLUSIONS: Buccal mucosal graft urethroplasty by ventral onlay for female urethral strictures yields effective, durable, and positively received outcomes. However, larger studies across multiple institutions are necessary to further assess its efficacy, especially regarding patient-reported experiences and sexual function.

RESUMEN

Introducción El objetivo de este estudio es evaluar y comparar la función eréctil (FE) tras la uretroplastia por escisión y anastomosis primaria (UEAP) y la uretroplastia con injerto de mucosa oral (UIMO) en la estenosis de uretra bulbar. Métodos Se identificó retrospectivamente a los pacientes tratados mediante uretroplastia. Se determinaron como criterios de inclusión en el estudio la edad entre 18 y 70 años y ser sexualmente activo. Los criterios de exclusión fueron la disfunción eréctil grave preoperatoria, estenosis distinta de la uretra bulbar, incompatibilidad psicosocial, estenosis uretral relacionada con fractura pélvica y tiempo de seguimiento inferior a un año. Como criterio de valoración primario, se utilizó el International Index of Erectile Function-5 (IIEF-5) para la comparación de la FE en el preoperatorio y en el 3.°, 6.° y 12.° mes tras la intervención quirúrgica. El criterio de valoración secundario fue el efecto de los datos demográficos, las características de la estenosis y del tratamiento sobre la FE. Resultados Tras aplicar los criterios de inclusión y exclusión, se identificó a 50 pacientes. De ellos, 30 fueron tratados mediante UEAP y 20 mediante UIMO. Al 3.er mes de la intervención, la FE mostró una disminución estadísticamente significativa en el grupo UEAP. En ambos grupos de pacientes se observó una mejoría de los efectos negativos postoperatorios sobre la EF en el 6.° mes, que recuperaron su nivel basal a los 12 meses. Conclusión Las técnicas UEAP y UIMO tienen un efecto similar sobre la FE a medio y largo plazo y ambas pueden utilizarse con seguridad y eficacia en el grupo de pacientes adecuado. (AU)

Introduction The aim of this study is to evaluate and compare erection function (EF) after excision and primary anastomosis urethroplasty (EPAU) and buccal mucosal graft urethroplasty (BMGU) in bulbar urethral stricture. Methods Patients who underwent urethroplasty were identified retrospectively. The criteria for inclusion in the study were determined as being over 18 years old and under 70 years old, being sexually active. Exclusion criteria are: preoperative severe erectile dysfunction, stricture outside the bulbar urethra, psychosocial incompatibility, urethral stricture related to pelvic fracture, follow-up time less than a year. As the primary endpoint, the International Index of Erectile Function-5 (IIEF-5) was determined as a comparison of EF in the preoperative and 3rd, 6th and 12th months after surgery. The secondary endpoint was the evaluation of the effects of demographic data, stricture and treatment characteristics on EF. Results Fifty patients were identified considering the inclusion/exclusion criteria. It was observed that there were 30 patients who underwent EPAU and 20 patients who underwent BMGU. At the third month after surgery, EF showed a statistically significant decrease in the EPAU group. In both patient groups, it was observed that the early negative effects after the operation in EF started to improve in the 6th month and returned to the baseline level by the first year. Conclusion EPAU and BMGU techniques have a similar effect on EF in the medium and long term. Both methods can be used safely and effectively in the appropriate patient group. (AU)

RESUMEN

Introducción La incontinencia urinaria de esfuerzo (IUE) constituye uno de los problemas de salud con mayor impacto en la vida de las personas. El objetivo del presente trabajo fue desarrollar una terapia para IUE dentro de la ingeniería de tejidos mediante aislamiento y cultivo de mioblastos autólogos (MAC), su implante endoscópico y el estudio de su eficacia en un modelo de incontinencia por esfinterotomía desarrollado en conejos. Materiales y métodos Se utilizaron conejos Nueva Zelanda, machos, sanos. Los animales fueron primero sangrados para obtención del plasma pobre en plaquetas (PPP) y biopsiados para el aislamiento de mioblastos. Posesfinterotomía, fueron divididos en dos grupos: grupo tratado (representado por aquellos animales que recibieron MAC resuspendidos en PPP) y grupo control (representado por aquellos animales que recibieron solo PPP). Se utilizó el punto de presión de pérdida (LPP) para medir la continencia de ambos grupos en diferentes instancias. Los resultados se evaluaron con modelos de regresión lineal jerárquica. Se efectuaron también estudios histológicos sobre los esfínteres de los conejos una vez finalizado el seguimiento. Resultados No se observaron diferencias estadísticamente significativas entre los valores basales de LPP de cada grupo. Los valores posesfinterotomía de ambos grupos estuvieron por debajo del 50% del valor basal, condición necesaria para considerarlos sujetos incontinentes. Los valores posimplante del grupo tratado fueron superiores al 50% del valor basal, permitiendo suponer una recuperación de la continencia. Se observó una diferencia estadísticamente significativa en los valores de LPP entre los dos grupos de tratamiento (p=0,003). El estudio histológico en el grupo tratado reveló islas interconectadas formadas por fibras musculares, mientras que en el grupo control se observó tejido conectivo periférico a la luz de la uretra e infiltrado inflamatorio. Discusión y conclusiones ... (AU)

Introduction Stress urinary incontinence (SUI) is one of the health problems with more impact on patients’ lives. The aim of the present work was to develop a therapy for SUI using tissue engineering by isolation and culture of autologous myoblasts (CAM) followed by endoscopic implantation. We also evaluated the efficacy of this therapy in a rabbit model of incontinence after sphincterotomy. Materials and methods We used healthy male New Zealand rabbits. The animals were first bled to obtain platelet-poor plasma (PPP) and biopsied for myoblast isolation. Post-sphincterotomy, they were divided into two groups: the treatment group (including animals that received CAM resuspended in PPP) and the control group (including animals receiving only PPP). The leak-point pressure (LPP) was used to measure continence in both groups at different time points. The results were evaluated with hierarchical linear regression models. Histological evaluation of the rabbits’ sphincters was also performed at the end of follow-up. Results No statistically significant differences were observed between the baseline LPP values of each group. The post-sphincterotomy values of both groups were below 50% of the baseline value, which was a mandatory condition for incontinence. The post-implantation values of the treatment group were higher than 50% of the baseline value, which led us to assume continence recovery. A statistically significant difference was observed in the LPP values between the two treatment groups (p=0.003). Histological study revealed interconnected islands formed by muscle fibers in the treatment group, and connective tissue surrounding the urethral lumen and inflammatory infiltrate in the control group. Discussion and conclusions The implantation of CAM significantly improved LPP values in the treatment group, and the improvement remained throughout the evaluation period. ... (AU)

RESUMEN

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.

RESUMEN

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)

RESUMEN

INTRODUCTION@#Placement of ureteral access sheath (UAS) prior to retrograde intra-renal surgery (RIRS) is done to provide easier re- entries, shorter operation time and better vision. However, some studies have associated the placement of UAS to increased morbidity and complications.@*OBJECTIVE@#The study aimed to compare outcomes of patients with nephrolithiasis who underwent RIRS with versus without placement of UAS.@*METHODS@#This is a retrospective cohort study among patients with nephrolithiasis who underwent RIRS with or without placement of UAS. The authors analyzed a total of 52 patients who underwent RIRS, 22 without, and 30 with UAS. Comparison of patients’ clinical profile, duration of post-operative hospital stay and the difference of their frequency were determined using Independent Sample T-test, Mann-Whitney U test and Fisher’s Exact test, respectively. STATA 15.0 was used for data analysis.@*RESULTS@#The two groups were similar in terms of clinical profile and operative outcomes. In terms of complications, there was one patient who had a failed surgery in the UAS group. Bleeding was reported in both groups. One-fourth of the patients had abdominal/bladder cramps and 13% had fever. Stone-free rate was 94% at 1 month and 92% at 3 months post-op. Readmission within 3 months was seen in four patients (8%) and retreatment was done on three patients (6%).@*CONCLUSION@#There is no significant difference in placing UAS or not prior to RIRS in terms of clinical profile and operative outcomes. Safety measures should be observed to prevent any bleeding and ureteral injuries during placement of UAS intra-operatively.

RESUMEN

Introducción y objetivos: A lo largo de los años los médicos que se ocupan de los trastornos urológicos pediátricos han recurrido a la ampliación vesical (AV), un procedimiento quirúrgico altamente desafiante desarrollado para preservar las funciones renales en diversos casos de anomalías urinarias congénitas. Este estudio tiene como objetivo revelar los resultados de la AV a muy largo plazo en una amplia muestra de pacientes pediátricos, así como el papel de la enfermedad subyacente en el pronóstico renal tras la AV.Materiales y métodosSe realizó un estudio transversal retrospectivo en 54 niños con anomalías urinarias congénitas que fueron sometidos a una AV. Se evaluó la técnica de ampliación utilizada, la localización de la implantación del uréter, las complicaciones y los hallazgos ecográficos. Se recogieron datos sobre los niveles de creatinina sérica en los registros preoperatorios y posteriores a la AV anuales.ResultadosDe los 54 niños 33 (61,1%) eran varones. Los diagnósticos fueron disrafismo espinal (DE) (n=13), válvula uretral posterior (VUP) (n=8), extrofia vesical (n=32) y traumatismo (n=1). La duración media del seguimiento fue de 18 (3-31) años. Las comparaciones de los niveles de creatinina sérica entre los grupos revelaron que, a pesar de que no existían diferencias significativas entre el grupo de extrofia vesical y el de VUP en el periodo preoperatorio ni en el primer año postoperatorio, los casos con VUP presentaban niveles de creatinina sérica significativamente más altos en los siguientes años posteriores a la cirugía. Además, en comparación con el grupo de DE, los sujetos con VUP tenían niveles significativamente más altos en el segundo (p=0,035) y décimo año (p=0,006) del postoperator. (AU)

Introduction and objectives: Throughout the years, clinicians dealing with pediatric urology disorders have resorted to bladder augmentation (BA), a demanding surgical procedure, to preserve renal functions in sundry congenital urinary tract defects. This study aimed to reveal the very long-term outcomes of BA in a large sample of pediatric patients and the role of underlying disease on renal prognosis after BA.Materials and methodsA retrospective cross-sectional study was conducted on 54 children with congenital urinary defects who underwent BA. The utilized augmentation technique, the location of ureter implantation, complications, and ultrasonography findings were analyzed. Data on serum creatinine levels were collected from preoperative records and anniversaries following BA.ResultsAmong 54 children, 33 (61.1%) were boys. Diagnoses were spinal dysraphism (SD) (n=13), posterior urethral valve (PUV) (n=8), bladder exstrophy (n=32) and trauma (n=1). The median follow-up duration was 18 (3-31) years. The comparisons of serum creatinine levels between groups revealed that, despite no meaningful difference was present between bladder exstrophy and PUV group in the preoperative period and postoperative 1st year, cases with PUV had significantly higher levels of serum creatinine levels in the following postoperative years. Therewithal compared with the SD group, subjects with PUV had significantly higher levels at the postoperative 2nd year (P=.035) and 10th year (P=.006).ConclusionsIn our study, significantly long-term follow-up outcomes could facilitate the pre- and postoperative approach for enterocystoplasty in children. According to our results, it is noteworthy that kidney functions are at high risk of worsening in subjects with PUV and underwent BA. (AU)

RESUMEN

Abstract The introduction of foreign bodies in the urethra are uncommon. Given its rarity, the approach to this condition is not standardized but it is highlighted that minimally invasive procedures should be prioritized depending on its feasibility. In the present study, we report a case of a 60-year-old male patient with bipolar disorder and a foreign body impacted in the bulbar urethra with open surgical resolution after a failed endoscopic treatment. We perform an analysis into the diagnostic and therapeutic methods used, with postopera tive results.

Resumen La introducción de cuerpos extraños uretrales es poco frecuente, razón por la cual, la mayoría de las publicaciones disponibles en la literatura son reportes de casos aislados o pequeñas series con gran heteroge neidad. Existen distintas aproximaciones frente a esta afección, desde métodos menos invasivos hasta cirugías abiertas más complejas. Presentamos un caso de cuerpo extraño impactado en uretra bulbar con el objetivo de analizar métodos diagnósticos empleados y aproximaciones terapéuticas concluyendo en la resolución quirúrgica convencional. Se evaluaron resultados postoperatorios.

RESUMEN

INTRODUCTION AND OBJECTIVES: Throughout the years, clinicians dealing with pediatric urology disorders have resorted to bladder augmentation (BA), a demanding surgical procedure, to preserve renal functions in sundry congenital urinary tract defects. This study aimed to reveal the very long-term outcomes of BA in a large sample of pediatric patients and the role of underlying disease on renal prognosis after BA. MATERIALS AND METHODS: A retrospective cross-sectional study was conducted on 54 children with congenital urinary defects who underwent BA. The utilized augmentation technique, the location of ureter implantation, complications, and ultrasonography findings were analyzed. Data on serum creatinine levels were collected from preoperative records and anniversaries following BA. RESULTS: Among 54 children, 33 (61.1%) were boys. Diagnoses were spinal dysraphism (SD) (n = 13), posterior urethral valve (PUV) (n = 8), bladder exstrophy (n = 32) and trauma (n = 1). The median follow-up duration was 18 (3-31) years. The comparisons of serum creatinine levels between groups revealed that, despite no meaningful difference was present between bladder exstrophy and PUV group in the preoperative period and postoperative 1st year, cases with PUV had significantly higher levels of serum creatinine levels in the following postoperative years. Therewithal compared with the SD group, subjects with PUV had significantly higher levels at the postoperative 2nd year (P = .035) and 10th year (P = .006). CONCLUSIONS: In our study, significantly long-term follow-up outcomes could facilitate the pre- and postoperative approach for enterocystoplasty in children. According to our results, it is noteworthy that kidney functions are at high risk of worsening in subjects with PUV and underwent BA.

RESUMEN

Objetivo: Evaluar los valores individuales del U-score como factores predictores de la cirugía uretral compleja.Métodos: Estudio transversal que incluye a los pacientes que recibieron una uretroplastia anterior entre 2011 y 2019. Se midieron las variables del U-score (etiología [1-2 puntos], número de estenosis [1-2 puntos], localización anatómica (1-2 puntos) y longitud [1-3 puntos]) de manera individual y total. La complejidad quirúrgica se definió como baja (anastomosis, injerto de mucosa oral y uretroplastia anterior ampliada) y alta (injerto doble de mucosa oral, colgajo y combinación de injerto y colgajo). Los componentes del U-score se incluyeron como predictores de cirugía compleja y como variables principales con estimaciones y comparaciones de los valores de probabilidad individuales. Se establecieron grupos según la probabilidad de riesgo de cirugía compleja.Resultados: Se incluyeron 654 pacientes. La edad media fue de 57,2 años. Se realizó cirugía de baja complejidad en 464 pacientes (259 anastomosis, 144 injertos, 61 uretroplastia anterior aumentada) y de alta complejidad en 190 (53 injerto doble de mucosa oral, 27 colgajo, 110 combinación injerto/colgajo). En el análisis multivariante, la longitud, el número de estenosis y la localización fueron predictores de complejidad. La introducción del U-score como única variable en el modelo univariante predijo una OR de 8,52 (IC 95%: 6,1-11). Los grupos del U-score simplificado obtenidos por probabilidad de complejidad fueron: riesgo bajo (4-5 puntos), riesgo intermedio (6 puntos) y riesgo alto de complejidad (7-9 puntos) La predicción del riesgo de probabilidad de cirugía compleja (IC 95%) para el grupo de riesgo bajo, medio y alto fue de 1,6 (0-2,9), 19,1 (13,8-25,9) y 77,9 (61,6-88,7), respectivamente.Conclusiones: El U-score puede utilizarse como una herramienta predictiva de la cirugía uretral compleja. Presentamos la herramienta de riesgo U-score simplificado para evaluar

Objective: To assess U-score individual values as urethral complex surgery predictors.Methods: Cross-sectional study including patients who received anterior urethroplasty from 2011 to 2019. U-score (etiology (1-2 points), number of strictures (1-2 points), anatomic location (1-2 points) and length (1-3 points)) was measured individually and globally. Surgical complexity was defined as low (anastomotic, buccal mucosal graft, and augmented anterior urethroplasty), and high complexity (double buccal mucosal graft, flap, and graft/flap combination). U-score components were included as complex surgery predictor and as main variable with individual probability values estimations and comparisons. Risk complex surgery probability groups were established.Results: 654 patients were included. Mean age was 57.2 years. Low complexity surgery was performed in 464 patients (259 anastomotic, 144 graft, 61 augmented anterior urethroplasty) and high complexity was done in 190 (53 double buccal mucosa graft, 27 flap, 110 graft/flap comb.). In multivariate analysis length, number of strictures and location were predictors of complexity. Introducing U-Score as only variable in univariate model predicted an OR 8.52 (95%CI 6.1-11). Simplified U-score grouping set obtained by complex probability was: low risk (4-5 points), medium risk (6 points) and high risk of complexity (7-9 points) Predicted risk of complex surgery probability (95%CI) for low, median and high risk group were 1.6 (0-2.9), 19.1 (13.8-25.9) and 77.9 (61.6-88.7), respectively.Conclusions: U-score can be used as a tool to predict complex urethral surgery. We present a simplified U-score risk tool to assess individual complex anterior urethroplasty probability (AU)

RESUMEN

Objetivo: Hemos empleado previamente la técnica de reparación mediante tubularización e incisión de la placa uretral (TIP) con algunas modificaciones en casos de hipospadias distal debido a sus excelentes resultados cosméticos. En este estudio se evaluaron los efectos de la espongioplastia y los colgajos de dartos dorsal y de las sondas uretrales cortas en los resultados de la reparación con TIP.Materiales y método: Sólo se incluyeron casos de hipospadias distal. Los pacientes elegibles se dividieron en dos grupos: el grupo A incluyó a los pacientes con reparación mediante espongioplastia con colocación de colgajo de dartos dorsal, mientras que el grupo B incluyó a los pacientes sometidos a reparación utilizando colgajo de dartos dorsal. Adicionalmente, el grupo A se dividió en dos subgrupos según el tipo de sonda utilizada (sonda vesical o sonda uretral corta).Resultados: Un total de 473 pacientes participaron en este estudio. No se observaron diferencias estadísticamente significativas en las tasas de complicaciones entre los dos grupos. En el grupo A se utilizó una sonda vesical en 107 pacientes y una sonda uretral corta en 135 pacientes. No se observaron diferencias estadísticamente significativas al comparar los resultados de los dos grupos.Conclusiones: La espongioplastia puede combinarse con la colocación de colgajo de dartos dorsal para reducir la necesidad de plicaturas dorsales, además de reducir la tasa de fístulas. Las sondas uretrales cortas pueden utilizarse de forma segura y sin efectos durante el postoperatorio en niños con control de esfínteres Objetivo Hemos empleado previamente la técnica de reparación mediante tubularización e incisión de la placa uretral (TIP) con algunas modificaciones en casos de hipospadias distal debido a sus excelentes resultados cosméticos. En este estudio se evaluaron los efectos de la espongioplastia y los colgajos de dartos dorsal y de las sondas uretrales cortas en los resultados de la reparación con TIP

Aim: We have previously employed the tubularized incised plate (TIP) repair technique in distal hypospadias cases with a few modifications because of its excellent cosmetic results. In this study, we aimed to evaluate the effects of spongioplasty and dorsal dartos flaps, in addition to short urethral stents on the outcomes of TIP repair.Materials and methods: Only distal hypospadias cases were involved in this study. Eligible patients were divided into two groups: group A included patients repaired with both spongioplasty and dorsal dartos flap placement, while group B included patients repaired with dorsal dartos flap placement alone. Group A was further divided into two subgroups according to the type of catheter used (bladder catheter or short urethral stent).Results: A total of 473 patients were included in this study. There was no statistically significant difference observed in the complication rates between the two groups. In Group A, a bladder catheter was used in 107 patients and a short urethral stent was used in 135 patients. When the results of the two groups were compared, there was no statistically significant difference.Conclusions: Spongioplasty could be combined with dorsal dartos flap placement to reduce the need for dorsal plication rather than to reduce the fistula rate. Short urethral stents can be used safely with no postoperative effects in children who have completed toilet training (AU)

RESUMEN

Background: Meatal advancement with glanduloplasty (MAGPI) has been in the recent years one of the most frequently surgical techniques used for the correction of distal hypospadias. Multiple modifications have been described to improve the results ofthis technique. In 2004 we presented the initial results of the New Modern MAGPI or DUAGPI (distal urethral advancement and glanduloplasty) as a surgical alternative to the original MAGPI. Objetive: The objective of the present study is to evaluate the applicability, safety and the cosmetic results obtained with this technique, as well as the long-term complications. Materials and Methods: Retrospective and descriptive study of patients with distal hypospadias, corrected using the DUAPI technique, between 2002 and 2018. Surgical technique: Initially, an artificial erection was performed, the absence of curvature in all patients is proven. A skin denudation was performed up to the base of the penis in those children with a bend greater than 30. Second, the distal urethral disconnection was performed at the posterior and lateral urethral level. A glandular triangular section is made to accommodate the distal urethra and to allow a conical appearance with a final glandular. Finally, the fixation of the distal urethral to the glandular tip and the anterior glandular closure is performed. We performed an annual follow-up of all patients. The analysis of all the variables collected during surgery and follow-up was done with SPSS 22 statistical package. Results: 90 patients meet inclusion criteria and were included in the study (32 glandular and 58 coronal). The mean surgical time was 47 minutes (Range: 37-71 minutes). The mean follow-up was 9.4 years (2.1-15 years). 2 patients had meatal stenosis after surgery, 4 mild glandular retraction, and 2 urethrocutaneous fistula. Six of the 8 patients with a complication were successfully reoperated (AU)

RESUMEN

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)
