Development and assessment of an ex-vivo bench model aimed at laparoscopic ureteric reconstructive techniques.

INTRODUCTION/BACKGROUND: Reconstructive and ablative urologic techniques require special technical mastery, especially the intracorporeal suturing. OBJECTIVE: To report the subjective evaluation of a versatile ex-vivo model aimed to practice laparoscopic ureteric reconstructive techniques (LURT) on box-trainer. STUDY DESIGN: The model is a continuous portion of porcine urinary bladder ("dilated pelvis"), the vesico-ureteral joint ("stenosis") and healthy ureter. All 127 participants (n = 119 urologists and n = 8 paediatric surgeons) performed on the model laparoscopic Anderson-Hynes dismembered pyeloplasty, and then, in the animal model, different LURT procedures (ureteroneocystostomy, ureteric reimplantation and/or dismembered pyeloplasty). The model was subjectively evaluated (face and content validity), through a 12 items questionnaire, based on a Likert scale (1-5 points) and a global question (1-10 points). RESULTS: The total mean rating for 11/12 items was very high (>4points). Only one was rated under 3 points. The overall total mean rating from 1 to 10 points was very high (9.19 ± 0.82 points). In 10/12 items, expert's feedback (content validity) prevailed over non-experts (face validity). DISCUSSION/CONCLUSION: The model was highly accepted for the practice of LURT techniques. Additionally, it is cost-effective, easy to assemble, ethically considerate, and realistic.

Actividad médico-quirúrgica y estado actual de la formación de los residentes de urología en España: Resultados de una encuesta nacional / Medical-surgical activity and the current state of training of urology residents in Spain: Results of a national survey

Objetivos: Conocer el estado actual de la actividad médico-quirúrgica y de la formación de los residentes de urología en España. Material y método: Se diseñaron 2 encuestas anónimas y fueron cargadas en la herramienta Google Docs© para ser contestadas vía online. El periodo de recolección online fue de septiembre de 2015-enero de 2016. Los datos recolectados fueron procesados utilizando el programa estadístico IBM SPSS para Windows, Versión 21.0 y el programa R versión 3.2.3. Resultados: El número de total de respondedores fue de 163. En referencia al número de guardias de presencia física la mayoría de los residentes realizan entre 4 y 6 guardias al mes. Ochenta y cuatro de los encuestados refieren estar menos de 20 horas semanales en quirófano y 43 de estos incluso menos de 10 horas. El 30% de los encuestados no ha realizado ninguna resección transuretral, la mayoría ha realizado al menos una adenomectomía prostática, pero a su vez no ha realizado ningún procedimiento oncológico mayor, ya sea por vía laparoscópica o abierta. En las preguntas destinadas a entrenamiento y cursos de formación encontramos que la mayoría de los residentes entrena laparoscopia en el hospital o en casa. La satisfacción global de la residencia fue valorada en 2,6. En este sentido podría considerarse la satisfacción global como moderada. Conclusiones: Se deberían orientar esfuerzos para estandarizar la adquisición de habilidades quirúrgicas y no quirúrgicas, garantizar el acceso a cursos de formación, establecer un mínimo de intervenciones requeridas por año y lograr una evaluación objetiva de la especialidad

Objectives: To determine the actual state of medical-surgical activity and training for urology residents in Spain. Material and method: We designed 2 anonymous surveys, which were uploaded with the Google Docs© tool so that the respondents could answer the surveys online. The online collection period was September 2015 to January 2016. The collected data were processing using the statistical programme IBM SPSS for Windows, Version 21.0 and the programme R version 3.2.3. Results: The total number of responders was 163. In reference to the number of physically present on-call residents, the majority conducted between 4 and 6 shifts a month. Eighty-four of those surveyed indicated that they were in the operating room less than 20hours a week, and 43 of these even less than 10hours. Thirty percent of those surveyed had not performed any transurethral resection. The majority had performed at least one prostatic adenomectomy, but had not performed any major oncologic procedure, either laparoscopically or openly. In the questions concerning training and training courses, we found that most of the residents trained in laparoscopy at the hospital or at home. The overall satisfaction for the residence was assessed at 2.6. Based on this score, the overall satisfaction could be considered moderate. Conclusions: Efforts should be directed towards standardising the acquisition of surgical and nonsurgical skills, ensuring access to training courses, establishing a minimum of required operations per year and achieving an objective assessment of the specialty

La evaluación de competencias quirúrgicas como complemento al método formativo. Revisión / The assessment of surgical skills as a complement to the training method. Revision

Contexto y objetivo: La adquisición y mejora de las habilidades quirúrgicas son un elemento fundamental en la formación de cualquier profesional. Si bien, la propia evaluación de estas constituye, por ahora, un campo con escaso desarrollado. El objetivo de este trabajo es analizar las particularidades de los diferentes sistemas de evaluación y establecer los criterios mínimos que debe reunir un sistema de evaluación de habilidades y conocimientos, como método de evaluación de competencias quirúrgicas en cirugía urológica. Adquisición de evidencias: Revisión de la literatura científica orientada a los diferentes sistemas de evaluación de habilidades y competencias, técnicas y no técnicas, disponibles en la actualidad, con especial atención a las revisiones sistemáticas realizadas y a los estudios prospectivos. Síntesis de evidencias: Tras la revisión efectuada, encontramos que los diferentes sistemas de evaluación de competencias quirúrgicas presentan, a nuestro juicio, una serie de carencias: existe cierto grado de subjetividad en la evaluación de un cirujano por parte del evaluador; no se recoge formalmente la evaluación de competencias no técnicas.; no se describe un seguimiento de la evaluación ni unos parámetros básicos asociados a calidad sanitaria y no existe un registro de competencias asociadas a las diferentes técnicas quirúrgicas, como tampoco se describe la graduación de las mismas y las particularidades específicas para su aplicación. Conclusiones: Entendemos necesario el desarrollo de un nuevo sistema de evaluación de competencias quirúrgicas, técnicas y no técnicas, orientado a la evaluación de urólogos en diferentes técnicas quirúrgicas. Para ello, nuestro equipo ha trabajado en el desarrollo del sistema Evaluation System for Surgical Competencies on Laparoscopy, fundamentado en la definición, graduación y evaluación de aquellas competencias que demuestra un cirujano

Context and objective: The acquisition and improvement of surgical skills constitute a fundamental element in the training of any practitioner. At present, however, the assessment of these skills is a scarcely developed area of research. The aim of this study was to analyse the peculiarities of the various assessment systems and establish the minimum criteria that a skills and knowledge assessment system should meet as a method for assessing surgical skills in urological surgery. Acquisition of evidence: Scientific literature review aimed at the various currently available assessment systems for skills and competencies (technical and nontechnical), with a special focus on the systematic reviews and prospective studies. Summary of the evidence: After conducting the review, we found that the various assessment systems for surgical competence have, in our opinion, a number of shortcomings. There is a certain degree of subjectivity in the assessment of surgeons by the evaluators. The assessment of nontechnical competencies is not formally recorded. There is no description of a follow-up assessment or any basic parameters associated with healthcare quality. There is no registration of associated competencies associated with the various surgical techniques. There is also no ranking of these competencies and the specific peculiarities for their application. Conclusions: We believe that the development of a new assessment system for surgical competencies (technical and nontechnical) aimed at assessing urologists in the various surgical techniques is necessary. To this end, our team has worked on developing the Evaluation System for Surgical Competencies on Laparoscopy, which is based on the definition, ranking and assessment of competencies demonstrated by surgeons

¿Ha dejado de disminuir la mortalidad por cáncer de próstata en España? / Has prostate cancer mortality stopped its decline in Spain?

Objetivo: Describir la evolución de la mortalidad por cáncer de próstata en España durante el periodo 1980-2013. Sujetos y método: Los datos de mortalidad por cáncer de próstata y las poblaciones necesarias para el cálculo de los indicadores fueron facilitados por el Instituto Nacional de Estadística. Se calcularon las tasas específicas por grupos de edad, crudas y estandarizadas globales mediante el método directo (población estándar europea), que se expresan como tasas por 100.000 personas-año. Para el análisis de tendencias de las tasas se utilizaron modelos de regresión joinpoint. Resultados: Las tasas ajustadas (globales) por edad en España descienden de 21,7 a 15,4 defunciones por 100.000 varones-año entre los años extremos del periodo estudiado (PCA: -0,9%; p < 0,05). El análisis joinpoint refleja 2 periodos: 1980-1998 (incremento del 0,7% anual; p < 0,05) y 1998-2013 en el que las tasas disminuyen de forma significativa (-3%; p < 0,05). Exceptuando las ciudades autónomas de Ceuta y Melilla, en las que las tasas permanecen estables a lo largo del periodo de estudio, el resto de comunidades muestran 1 o 2 puntos de inflexión en las tendencias y todas muestran un periodo final con descenso de las tasas (exceptuando Galicia y Cataluña, en las que en el periodo 2008-2013 se estabilizan). Conclusión: El descenso de la mortalidad por cáncer de próstata en España parece haberse detenido en Galicia y Cataluña

Objective: To describe the evolution of prostate cancer mortality in Spain during the period 1980-2013. Subject and method The prostate cancer mortality data and population data needed to calculate the indicators were provided by the National Institute of Statistics. We calculated the specific rates by age group, raw and standardised globally using the direct method (European standard population). The rates are expressed for 100,000 person-years. For the analysis of trends in the rates, we used joinpoint regression models. Results: The overall rates adjusted for age in Spain decreased from 21.7 to 15.4 deaths per 100,000 men-years between the starting and ending date of the study period (annual percentage change: -.9%; P < .05). The joinpoint analysis reflects 2 periods: 1980-1998 (.7% annual increase; P < .05) and 1998-2013, during which the rates decreased significantly (-3%; P < .05). Except for the autonomous cities of Ceuta and Melilla where the rates remained stable over the course of the study period, the communities showed 1 or 2 points of inflection in the trends, and all had a final period with a reduction in the rates (except for Galicia and Catalonia, where the rates stabilised in 2008-2013). Conclusion: The decline in prostate cancer mortality in Spain appears to have stopped in Galicia and Catalonia

Comparación de datos anatomopatológicos entre biopsia de próstata y pieza de prostatectomía radical en pacientes con cáncer de bajo y muy bajo riesgo / Comparison of pathological data between prostate biopsy and radical prostatectomy specimen in patients with low to very low risk prostate cancer

Objetivo: Analizar la correlación entre los datos anatomopatológicos encontrados en prostatectomía radical y la biopsia previa realizada en pacientes con cáncer de próstata de bajo riesgo. Material y métodos: Se ha realizado un estudio descriptivo transversal para valorar las características de las prostatectomías radicales realizadas en nuestro centro desde enero de 2012 a noviembre de 2014. Los criterios de inclusión fueron pacientes con enfermedad de bajo riesgo (cT1c-T2a, PSA ≤ 10 ng/ml y Gleason ≤ 6). Fueron excluidos aquellos con menos de 8 cilindros en la biopsia, número de cilindros afectos no especificados, tacto rectal no recogido en historia clínica o biopsia realizada en otro centro. Resultados: De las 184 prostatectomías realizadas en este periodo, 87 pacientes cumplían con los criterios de inclusión y 26 de estos presentaban < 3 cilindros afectados y un PSAd ≤ 0,15 (muy bajo riesgo). Encontramos en la muestra total un porcentaje de infragradación (Gleason ≥ 7) del 18,4% (IC 95%: 10,3-27,6%) y de afectación extracapsular (pT3) del 10,35% (IC 95%: 4,6-17,2%). El porcentaje de márgenes positivos fue del 21,8% (IC 95%: 12,6-29,9%). En el grupo de muy bajo riesgo no encontramos ningún caso de afectación extracapsular y un solo caso de infragradación (Gleason 7 [3 + 4]) representando un 3,8% del total (IC 95%: 0-12,5%). Resultaron ser variables predictoras de no correlación (estadio ≥ pT3a o infragradación) el grupo de riesgo inicial, volumen, PSA densidad y cilindros afectados. Conclusiones: El volumen prostático, el valor del PSA densidad, el número de cilindros afectados y el grupo de riesgo inicial del paciente influyen en la aparición de datos de mal pronóstico anatomopatológico en la pieza de prostatectomía radical (afectación extracapsular y Gleason ≥ 7)

Objective: To analyze the correlation between pathological data found in radical prostatectomy and previously performed biopsy in patients at low risk prostate cancer. Material and methods: A descriptive, cross-sectional study was conducted to assess the characteristics of radical prostatectomies performed in our center from January 2012 to November 2014. The inclusion criteria were patients with low-risk disease (cT1c-T2a, PSA ≤ 10 ng/mL and Gleason score ≤ 6). We excluded patients who had fewer than 8 cores in the biopsy, an unspecified number of affected cores, rectal examinations not reported in the medical history or biopsies performed in another center. Results: Of the 184 patients who underwent prostatectomy during this period, 87 met the inclusion criteria, and 26 of these had < 3 affected cores and PSA density ≤ .15 (very low risk). In the entire sample, the percentage of undergrading (Gleason score ≥ 7) and extracapsular invasion (pT3) was 18.4% (95% CI 10.3 − 27.6) and 10.35% (95% CI 4.6 − 17.2), respectively. The percentage of positive margins was 21.8% (95% CI 12.6-29.9). In the very low-risk group, we found no cases of extracapsular invasion and only 1 case of undergrading (Gleason 7 [3 + 4]), representing 3.8% of the total (95% CI 0 - 12.5). Predictors of no correlation (stage ≥ pT3a or undergrading) were the initial risk group, volume, PSA density and affected cores. Conclusions: Prostate volume, PSA density, the number of affected cores and the patient's initial risk group influence the poor pathological prognosis in the radical prostatectomy specimen (extracapsular invasion and Gleason score ≥ 7)

[Early experience in laparoscopic radical prostatectomy using the laparoscopic device for umbilical access SILS Port]. / Experiencia inicial en prostatectomía radical laparoscópica con el dispositivo de acceso laparoscópico umbilical Single-Incision Laparoscopic Surgery Port.

Since 2007, various urological procedures have been performed with laparoendoscopic single-site surgery (LESS surgery), including nephrectomy, pyeloplasty, simple prostatectomy and, with the refinement of laparoscopic instrumentation, radical prostatectomy. This paper reports our initial experience in radical prostatectomy using the SILS Port from Covidiem and two lateral 5-mm trocars for triangulation. The SILS Port allows for accurate, simple insertion through a Hadson incision. The flexible port accommodates three 5-mm cannulas or two 5-mm cannulas and a 12-mm port for easier instrument exchange through a single incision. This approach decreases morbidity from bleeding, hernia and/or internal organ damage and improves cosmetic. One-port single-incision laparoscopy is part of the natural development of minimally invasive surgery. Future research is required to assess the intraoperative and postoperative benefits of LESS surgery as compared to standard laparoscopy.

Experiencia inicial en prostatectomía radical laparoscópica con el dispositivo de acceso laparoscópico umbilical Single-Incision Laparoscopic Surgery Port® / Early experience in laparoscopic radical prostatectomy using the laparoscopic device for umbilical access SILS Port®

Desde el año 2007 se están realizando distintos procedimientos en cirugía laparoendoscópica por puerto único (laparoendoscopic single-site surgery), incluyendo nefrectomía, pieloplastia, adenomectomía prostática y, con el perfeccionamiento del instrumental laparoscópico, prostatectomía radical. Presentamos nuestra experiencia inicial en prostatectomía radical laparoscópica utilizando el dispositivo Single-Incision Laparoscopic Surgery Port® de Covidien y 2 trocares auxiliares de 5mm colocados lateralmente para triangulación. El Single-Incision Laparoscopic Surgery Port® permite una inserción precisa y sencilla a través de una incisión de Hadson. El puerto flexible contiene 3 cánulas de 5mm o 2 cánulas de 5mm y una de 12mm para facilitar el intercambio de instrumental a través de la incisión única. Este abordaje disminuye la morbilidad por sangrado, hernias y/o lesión de los órganos internos y mejora los resultados cosméticos. El puerto único forma parte del desarrollo natural de la cirugía mínimamente invasiva. Se necesita más experiencia para determinar los beneficios intra y postoperatorios de la cirugía laparoendoscópica por puerto único en comparación con la laparoscopia convencional (AU)

[A Spanish multicenter trial of TVT for female urinary incontinence]. / TVT para la incontinencia urinaria femenina: estudio multicéntrico español.

OBJECTIVE: The purpose of this study was to evaluate results and complications of TVT in a large series from different hospital centers in Spain. METHOD: We retrospectively studied the results of TVT placement from 6 centers with 272 consecutive patients (median follow-up was 636 days). All types of stress urinary incontinence with a surgical indication were included and no previous conditions were established regarding the indication. No protocol was used for either the intervention or postoperative support measures. Data collection was protocolized and carried out using a common questionnaire that was completed by an urologist at each center from 3 to 6 months after the intervention and then annually. All patients who underwent intervention were asked about their satisfaction with the outcome. Multivariate studies were made to identify the factors that influenced the recovery of continence and the occurrence of complications. RESULTS: 92.1% of patients were continent and 2.4% have not shown any improvement. 91.6% of the patients claimed to be satisfied whereas only 2.7% were dissatisfied. After four years only 2.8% of patients showed mild incontinence with time and 0.4% had moderate incontinence. Only previous surgery for incontinence was found to be significantly unfavorable factor for achieving postoperative continence. CONCLUSION: We have reproduced a scenario closer to daily clinical reality than the results of series from a single institution or analyses using stricter selection criteria. This multicenter study verifies the viability and reproducibility of TVT with minimal complications in centers where patients are not selected and where not all urologists are specialized in urinary incontinence.

TVT para la incontinencia urinaria femenina: estudio multicéntrico español / A spanish multicenter trial of TVT for female urinary incontinence

Objetivo: Evaluar resultados y complicaciones del TVT en una gran serie multicéntrica española. Método: Estudio retrospectivo de 272 pacientes consecutivas con colocación de TVT en 6 centros españoles (mediana seguimiento 636 días). Se incluyó cualquier tipo de incontinencia de esfuerzo con indicación quirúrgica. No se utilizó protocolo de uniformidad para la intervención ni cuidados postoperatorios. Recogida de datos, estandarizada a 3, 6 meses y anualmente tras intervención. Se realizó estudio multivariado para identificar factores influyentes en la recuperación de la continencia y aparición de complicaciones. Se valoró la satisfacción de la paciente respecto a la intervención. Resultados: El 92,1% de las pacientes obtuvieron la continencia frente al 2,4% que no mostraron ninguna mejoría. A los cuatro años sólo el 2,8% de las pacientes mostraron incontinencia mínima y el 0,4% incontinencia moderada en el tiempo. Solo se encontró como factor influyente (desfavorable) para continencia postoperatoria el antecedente de cirugía previa anti-incontinencia. 91,6% declararon estar satisfechas mientras que sólo el 2,7% estaban insatisfechas. Conclusión: Creemos haber reproducido un escenario cercano a la realidad clínica diaria. El estudio multicéntrico verifica la viabilidad y reproducibilidad de los resultados del TVT con mínimas complicaciones en pacientes no seleccionadas y en centros donde no todos los urólogos están especializados en incontinencia urinaria (AU)

[Prostatic exfoliative cytology obtained from urine samples after massage. Initial results]. / Citología exfoliativa prostática obtenida en muestras de orina tras masaje. Primeros resultados.

INTRODUCTION: The same as the exfoliative cytology is a routine method to diagnose bladder tumour, the prostatic cytology obtained after massage may become a useful procedure to diagnose prostate cancer. OBJECTIVE: To obtain suitable prostatic cytologic material. To establish the role of the exfoliative cytology to diagnose cancer. MATERIAL AND METHODS: We made a prospective longitudinal descriptive study with 60 patients out of 150 (all of them with possible prostate cancer) for two years. We compared cytologic discoveries (urine after massage) with histological parameters (biopsies). RESULTS: When the cytology fulfills a series of requirements (a high number of prostatic cells, anisokariosis and antibodies Ki-67+) and these are compared with the histological data, we obtained a specificity of 100% and a sensibility of 67% for prostatic cancer. With this information the cytology reaches a predictive value of 100% and negative of 92%. CONCLUSIONS: It is possible to obtain prostatic cytologic material in a simple and easy way. The prostatic cytology may become a valid and useful method to diagnose the carcinoma of the prostate. Also this material can be used for multiple diagnostic, follow-up and research procedures.

Citología exfoliativa prostática obtenida en muestras de orina tras masaje. Primeros resultados / Exfoliative prostatic cytology obtained in urine samples after massage. First results

INTRODUCCIÓN: Al igual que la citología exfoliativa es un método de rutina en el diagnóstico del cáncer vesical, la citología prostática obtenida tras masaje puede llegar a ser un procedimiento de utilidad diagnóstica en el cáncer prostático. OBJETIVOS: Obtener material citológico prostático adecuado. Establecer el papel de la citología exfoliativa prostática en el diagnóstico del cáncer. MATERIAL Y MÉTODOS: Llevamos a cabo un estudio descriptivo, longitudinal y prospectivo, del que presentamos los resultados preliminares, sobre 60 pacientes de un total de 150, con sospecha de cáncer prostático, en un periodo de dos años. Comparamos hallazgos citológicos (orina tras masaje) con parámetros histológicos (biopsias).RESULTADOS: Cuando la citología cumple una serie de requisitos (elevado número de células prostáticas, anisocariosis y anticuerpo Ki-67 +) y estos se comparan con los datos histológicos, obtenemos para el cáncer prostático una específicidad del 100 per cent y una sensibilidad de 67 per cent. Con este tamaño de muestra la citología alcanza un valor predictivo del 100 per cent y negativo del 92 per cent. CONCLUSIONES: Es posible la obtención de material citológico prostático de forma simple y sencilla. La citología prostática puede llegar a ser un método útil y válido en el diagnóstico del carcinoma de la próstata. Este material además se puede utilizar para múltiples procedimientos diagnósticos, de seguimiento y de investigación (AU)

[Second resection in patients with Ta-T1 bladder tumors]. / Segunda resección en pacientes con tumores vesicales Ta-T1.

OBJECTIVES: To study the incidence of "residual/recurrence" tumor after a second bladder resection (2nd TUR). METHODS: 40 patients with new or recurrent superficial bladder tumor underwent repeat transurethral resection within 3 months after the initial resection. 37 patients were staged as Ta-T1. We study the incidence of tumor after the 2nd TUR both macroscopically detected or included in the bladder scar. We also study the influence of possible factors as the time between both resections, stage, grade, number of tumor size, localization in the bladder, primary or recurrent tumor and tumor pattern. RESULTS: After the 2nd TUR we found tumor in 14 of 37 (37.8%) Ta-T1 bladder tumors. Among the 14 tumors, 10 (71.5%) were macroscopically visible tumors and 4 cases the tumor were found after resection of the bladder scar of the first resection. We did not find relation between the presence of tumor in the 2nd TUR and any of the variables. CONCLUSIONS: After a TUR of superficial bladder tumor the complete removal of tumor is not always achieved. The early 3 months cystoscopy may not find residual tumor. Although we have found tumor in 37.8% in the 2a TUR we can not recommend routine 2nd TUR in superficial bladder cancer.

Segunda resección en pacientes con tumores vesicales Ta-T1 / Second TUR in patients with stage Ta-T1 transicional cell carcinoma of the bladder

OBJETIVO: Estudiar la incidencia de tumor "residual/recidivante" tras segunda resección precoz (2ª RTU), y que factores influyen en su hallazgo. MATERIAL Y MÉTODO: Estudio prospectivo de 40 pacientes con neoplasia vesical superficial a los que se les realizó una 2ª RTU precoz. Como posibles factores de riesgo de hallazgo de tumor se estudiaron el intervalo de tiempo entre ambas RTU, el estadio, el grado, el número de implantes tumorales, el tamaño de los implantes, localización dentro de la vejiga, tumor primario o recidivante y el patrón tumoral. RESULTADOS: Al realizar la 2ª RTU se confirmó histológicamente tumor en 14 (37,8 por ciento) de 37 pacientes con tumores Ta-T1 (excluimos aquellos con afectación focal de la muscular): 10 (71,5 por ciento) eran tumores macroscópicamente visibles, en 4 casos (28,5 por ciento) se encontró tumor al biopsiar las áreas de cicatriz/edema de la resección anterior. No encontramos asociación entre la presencia de tumor en la 2ª RTU y ninguna de las variables en estudio. CONCLUSIONES: La erradicación de tumor vesical superficial mediante RTU no se consigue en un elevado porcentaje de pacientes. La cistoscopia a los tres meses no puede excluir tumor residual. Aunque hemos encontrado 37,8 por ciento de tumor en la 2ª RTU, actualmente no podemos recomendarla de forma rutinaria en los tumores vesicales superficiales (AU)

[Congenital bladder diverticulum and Ehlers-Danlos syndrome: an unusual association]. / Divertículo vesical congénito y síndrome de Ehlers-Danlos: una rara asociación.

The existence of a vesical diverticulum in the context of a congenital connective tissue disorder such as Ehlers-Danlos syndrome led us to consider the possibility of a relationship. Four types of diverticula can be found in the literature: congenital, acquired, iatrogenic and syndrome-associated. Within the later, Ehlers-Danlos syndromes type IV and IX, even type V, are associated to the existence of vesical diverticula. The potential spontaneous rupture of the diverticulum is a typical feature, as well as post-surgery relapse. The attitude towards such diverticula should be one of watchful waiting, and simple, plasty-free diverticulectomy on the bladder's neck is indicated when performing a surgical procedure.
