Seminoma en paciente con Síndrome de Kartagener / Testicular seminoma in a patient with Kartagener's syndrome

Objetivo: Presentar la asociación de seminoma en paciente afecto de SK y su relación con la fertilidad. Métodos: Se describe la presencia de un seminoma en paciente afecto de SK, haciendo hincapié en la posible correlación de ambas patologías con la fertilidad, así como se comentan citas bibliográficas de interés. Resultado: Paciente con tumor testicular y SK al que se realizó orquiectomía, resultando ser un seminoma en el estudio anatomopatológico. Se realizaron dos espermiogramas en los que se corroboró la azoospermia, siendo difícil de diferenciar la posible implicación de ambas patologías en relación con la ausencia de espermatozoides en el eyaculado. Conclusiones: Presentamos un caso de seminoma en paciente afecto de SK y azoopermia. Tras la orquiectomía la evolución es favorable, haciéndose breve referencia bibliográfica al SK y sus potenciales implicaciones en la fertilidad. La asociación de este síndrome con tumor testicular es excepcional en la bibliografía consultada (AU)

Objective: To present the association between Seminoma and Kartagener's Syndrome (KS), and its relation with infertility. Methods: We report one case of Seminoma in a patient with Kartagener's Syndrome, focussing on the possible relation between both pathologies and fertility. Bibliographic references are discussed. Results: Orchyectomy was performed on a patient with Kartagener's Syndrome and testicular tumour. The pathology result was Seminoma. Azoospermia was obtained twice in the postoperative espermiogram, not being easy to establish the implication of each pathology (KS or Seminoma) in infertility. Conclusions: A patient with KS and Seminoma plus azoospermia is reported, with a great outcome from the oncological point of view. Bibliographic references are described. The association between KS and Seminoma is exceptional in the literature (AU)

Trasplante renal sobre prótesis aortobifemoral / renal transplantation in patients with a vascular aortobifemoral prosthesis

Introducción: Cada vez es más frecuente en la práctica clínica, la existencia de pacientes en insuficiencia renal terminal subsidiarios de trasplante renal que han recibido con anterioridad una cirugía protésica de revascularización. Hasta hace poco tiempo, estos pacientes eran desestimados como candidatos a trasplante renal. Contamos aquí nuestra experiencia en cinco casos. Material y métodos: De un total de 1483 trasplantes renales, 5 eran pacientes portadores de prótesis aorto-bifemoral (2 por aneurisma y 3 por enfermedad oclusiva). Revisamos las características, evolución y complicaciones de estos pacientes. Resultados: El injerto vascular se había colocado entre 6 meses y 16 años antes del trasplante. La técnica quirúrgica del trasplante fue la clásica, anastomosando la arteria renal al injerto vascular. Complicaciones quirúrgicas fueron; 1 trombosis de la arteria renal que precisó trombectomía y 1 estenosis ureterovesical. 2 pacientes fallecieron con injerto funcionante por neumonía a los 6 meses y 7 años, 3viven con injerto funcionante a los 7 meses, 3 y 7 años. Durante la evolución aparecieron otras complicaciones vasculares no relacionadas con el trasplante. Conclusión: El trasplante renal sobre prótesis aorto-bifemoral es una opción válida en pacientes seleccionados (AU)

Introduction: Nowadays, it is much more common in end stage renal disease patients with vascular grafts, to be kidney transplant candidates. We expose our experience in five cases. Material and methods: Of all 1,483 kidneys transplanted in our center, 5 recipients had a previous aortobifemoral bypass (2 due to abdominal aortic aneurysm, and 3 due to vascular occlusive disease). We review the clinical features, outcome and complications in these patients. Results: The vascular surgery was done 6 months to 16 years prior to transplantation. The renal transplant was done in iliac foss a with arterial anastomosis to the vascular graft. Surgical complications were: 1 renal artery thrombosis that was treated with thrombectomy, and 1 stricture at the ureterovesical junction. 2 patients dead at 6 months and 7 years with a functioning allograft and 3 patients live with functional allograft at 7 months, 3 years and 7 years. Conclusion: Kidney transplantation may be successful in selected patients with aortobifemoral bypass (AU)

[Mediastinal lymph nodes during the course of a metastatic prostate cancer]. / Adenopatías mediastínicas en la evolución de un cancer de próstata metastásico.

Prostate carcinoma is one of the most frecuent cancers in men. Significant numbers of patients have regional lymph node and bone metastases during the course of the disease. Mediastinal lymphadenopathy and cutaneous metastases are uncommon and signify well-advanced disease. We report the case of a patient with prostate cancer who develops mediastinal lymphadenopathy, pulmonary nodules and cutaneous metastases 8 years after the diagnosis.

Adenopatías mediastínicas en la evolución de un cáncer de próstata metastásico / Mediastinal lymph nodes during the course of a metastatic prostate cancer

El cáncer de próstata es uno de los tumores más frecuentes. Un número importante de pacientes presentarán adenopatías regionales y metástasis óseas en el curso de la enfermedad. Sin embargo, las adenopatías mediastínicas y las metástasis cutáneas son infrecuentes y significan enfermedad avanzada. Presentamos el caso de un paciente diagnosticado de cáncer de próstata que desarrolla adenopatías mediastínicas, nódulos pulmonares y metástasis cutáneas, 8 años después del diagnóstico

[In vitro three-dimensional reconstruction of human bladder mucosa]. / Reconstrucción tridimensional in vitro de mucosa vesical humana.

OBJECTIVE: The purpose of this study is to apply the in vitro keratinocyte culture techniques and the tissue engineering principles to human urothelium, to reconstruct an in vitro three-dimensional human bladder mucosa, suitable for grafting. MATERIAL AND METHODS: Biopsy specimens of human bladder mucosa were obtained from patients undergoing suprapubic prostatectomy, in vitro cultured and finally, an immunohistochemical study was made. RESULTS: A three-dimensional in vitro tissue was obtained, composed of a bio-artificial submucosa (fibrin gel and fibroblast) where the uroepithelial cells were seeding. We used a biodegradable polyglycolic acid mesh to facilitate the tissue manipulation and implantation. An immature epithelium was obtained with a weak immunostaining to cytokeratins. The immunohistochemical study could not demonstrate the development of basement membrane. CONCLUSIONS: In vitro keratinocyte culture techniques could be applied to other epithelial tissues like the urothelium. We obtained a three-dimensional in vitro tissue suitable for grafting in a relatively short time, which needs the matrix interactions in order to mature.

Reconstrucción tridimensional in vitro de mucosa vesical humana / In vitro three-dimensional reconstruction of human bladder mucosa

Objetivo: Aplicar las técnicas de cultivo in vitro de queratinocitos así como los principios de la ingeniería tisular al epitelio urinario humano, con el fin de reconstruir tridimensionalmente una mucosa vesical humana in vitro, apta para trasplantar. Material y Métodos: Se obtuvieron muestras de mucosa vesical de pacientes programados para cirugía abierta de próstata, previo consentimiento de los mismos, las cuales fueron cultivadas in vitro, para proceder posteriormente al estudio histomorfológico de los tejidos obtenidos. Resultados: Se obtuvo un tejido tridimensional compuesto por una submucosa bioartificial a base de un gel de fibrina y fibroblastos, sobre la que descansan las células uroepiteliales, pudiendo utilizar una malla de ácido poliglicólico, que facilite la manipulación de la mucosa y el posterior injerto de la misma. El tejido obtenido tenía el aspecto de un epitelio inmaduro con muy escasa reacción a citoqueratinas, sin poderse demostrar inmunohistoquímicamente el desarrollo de una membrana basal. Conclusiones: Las técnicas de cultivo in vitro de queratinocitos son aplicables a otros epitelios, entre ellos el urotelio humano. En un periodo de tiempo relativamente corto se puede obtener un tejido in vitro tridimensional apto para trasplantar, precisando posiblemente de las interacciones con el lecho receptor para poder madurar

[Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis]. / Quiste epidermoide testicular: una rara entidad de dificil diagnostico preoperatorio.

Intratesticular epidermoid cysts are rare tumours that constitute one percent of all testicular masses. They are bening lesions that make differential diagnosis from malignant testicular tumours difficult. The absence of serum markers elevation and ultrasound imaging could support these lesions being bening epidermoid cysts, and in that case, conservative surgery is adequate. We present the case of a 22 years old patient who complains of a left testicular mass. In this case ultrasound diagnosis was non-specific and a left radical inguinal orchiectomy was performed.

Quiste epidermoide testicular: una rara entidad de difícil diagnostico preoperatorio / Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis

Los quistes epidermoides intratesticulares son tumores raros, constituyendo el 1% de todos los tumores testiculares. Se trata de tumoraciones benignas que plantean un difícil diagnóstico diferencial preoperatorio frente a los tumores malignos testiculares. La ausencia de elevación de los marcadores tumorales y la apariencia ecográfica, pueden orientar hacia su diagnóstico preoperatorio y en este caso la cirugía conservadora del testículo. Se presenta el caso de un paciente de 22 años que consulta por una masa en el testículo izquierdo. En este caso, el diagnóstico ecográfico preoperatorio no descartaba otras patologías por lo que se procedió a la realización de orquiectomía inguinal izquierda (AU)

[Surgical aspects in the third and fourth kidney retransplant]. / Aspectos quirúrgicos en los terceros y cuartos retrasplantes renales.

INTRODUCTION AND OBJECTIVES: A quarter of patients waiting for kidney transplantation are patients with previous graft failure. Outcome of first and second renal transplant make these the gold standard for end renal stage disease, but this is not so clear in the case of third and further renal transplant, especially at the time of organ shortage. We revise our experience in patients with three or more kidney transplants focusing on surgical aspects and graft outcome. MATERIAL AND METHOD: 1364 renal transplants have been carried out in our centre since 1975 until December 2003. We have retrospectively revised the 34 patients with three renal transplants and the 5 with four. We analyse the surgical technique, surgical complications and graft outcome. RESULTS: Mean age was 42 years (21-65). Average mismatches between donor and recipient was 3.2. All kidneys, but one case of living donor, were harvested from cadaver donors, mostly in multiple organ-procurement. Average time from the last renal transplant was 5 years (3 days-17 years) and from the last transplant carried out in the iliac fossa reused until the new transplant was 9 years (3 days- 17.5 years). All implants were performed through an iterative lumboliliac incision (25 on the right side, 11 on the left one and in 3 cases where side was not registered). Mean average duration of the procedure was 166 minutes (100-300). Nephrectomy of previous graft at the moment of the implant was carried out in 13 patients (33%). Vascular anastomosis was made on the common iliac vessels (50%) or on the external ones (50%) in end to side way, Ureteroneocystostomy was performed in an extravesical way except in 1 patient with cutaneous diversion. Vascular complications were 4 haemorrages (1 patient died), 3 venous and 2 arterial thrombosis. We had an abscess secondary to intestinal fistulae. Other surgical complications were 4 lymphoceles, three of them needed surgical treatment, and one perirenal haematoma treated in a conservative way. No urological complications were seen. In total 6 grafts (15%) were lost due to surgical complications. Graft actuarial survival rate at 1 year was 65%, 40% at 5 and 28% at 10 years. CONCLUSIONS: Three and four renal transplant survival rates are shorter than first and second ones. Iterative access through lumboiliac incision is associated with a higher vascular complication rate, probably in these patients a transperitoneal access would be better. Multicentric studies with higher numbers of patients are needed to define more clearly which patients would benefit from multiple kidney retransplants.

Aspectos quirúrgicos en los terceros y cuartos retrasplantes renales / Surgical aspects in the third and fourth kidney retransplant

Introducción y objetivos: El fracaso de un injerto renal previo constituye la cuarta parte de los pacientes en lista de espera para trasplante renal. Si bien los resultados de los primeros y segundos trasplantes hacen que sean el tratamiento prioritario de la insuficiencia renal crónica, no es tan evidente que el tercer o más trasplante sea la mejor elección especialmente dada la escasez de órganos. Revisamos nuestra experiencia en pacientes con tres o más trasplantes renales con especial atención a los aspectos quirúrgicos y evolución del injerto. Material y método: Entre 1975 y diciembre de 2003 hemos realizado 1.364 trasplantes renales. Hacemos una revisión retrospectiva de los 34 pacientes con 3 trasplantes y 5 con 4 trasplantes. Analizamos fundamentalmente la técnica y complicaciones quirúrgicas y la evolución del injerto. Resultados: La edad media fue de 42 años (21-65). La media de incompatibilidades entre donante y receptor fue de 3,2. Todos, excepto 1 caso de donante vivo, fueron donantes cadáveres, la mayoría multiorgánicos. El tiempo medio desde el trasplante previo fue de 5 años (3 días-17 años) y entre la última cirugía en la fosa ilíaca reutilizada y el trasplante fue de 9 años (3 días y 17,5 años). En todos los casos se utilizó una incisión lumboilíaca iterativa (25 derecha, 11 izquierda, 3 no consta); el mayor problema quirúrgico fue la existencia de fibrosis en la fosa ilíaca. La duración media de la intervención fue de 166 minutos (100-300). En 13 pacientes (33%) se realizó trasplantectomía en el mismo acto quirúrgico. La anastomosis vascular se hizo en los vasos ilíacos comunes (50%) o externos (50%). La ureteroneocistostomía se hizo mediante técnica extravesical excepto en 1 caso con derivación a piel. Complicaciones vasculares: 4 hemorragias (1 exitus), 3 trombosis venosas y 2 arteriales. Hubo 1 absceso del lecho secundario a una fístula intestinal. Otras complicaciones fueron 4 linfoceles precisando tratamiento quirúrgico 3 de ellos y un hematoma perirenal que no precisó cirugía. No hubo complicaciones urológicas. En total se perdieron 6 injertos (15%) por las complicaciones quirúrgicas. La supervivencia actuarial del injerto fue del 65% al año, 40% a los 5 años y 28% a los 10. Conclusiones: La supervivencia de los 3º y 4º trasplantes renales es menor que la de los 1º y 2º. La cirugía mediante abordaje iterativo es dificultosa y se asocia a un mayor índice de complicaciones vasculares. Se precisan estudios multicéntricos con un mayor número de pacientes para poder concluir qué pacientes se beneficiarían de los múltiples retrasplantes (AU)

Estudio experimental sobre la viabilidad del injerto libre de epitelio urinario autólogo cultivado in vitro / Experimental study about viability of autologous free graft in vitro cultivated urinary epithelium

OBJETIVO: Con el presente trabajo pretendimos aplicar las técnicas de cultivo in vitro de queratinocitos así como los principios de la ingeniería tisular al epitelio urinario, con el fin de conseguir un tejido autólogo tridimensional apto para trasplantar, y confirmar a su vez la viabilidad del injerto libre del mismo en un modelo experimental. MATERIAL Y MÉTODOS: Se procedió a un diseño experimental en el animal de laboratorio donde se aplicaron las técnicas del cultivo celular y de la ingeniería de tejidos. Se obtuvieron muestras de mucosa vesical de conejo, las cuales fueron cultivadas in vitro, implantándose posteriormente el tejido obtenido en cada animal, estableciéndose 3 grupos, con diferentes periodos de seguimiento (7,14 y 30 días), para proceder al estudio histomorfológico de la viabilidad de dichos implantes. RESULTADOS: Se obtuvo un tejido tridimensional compuesto por una submucosa bioartificial a base de un gel de fibrina y fibroblastos, sobre la que descansan las células uroepiteliales, utilizando una malla de ácido poliglicólico, la cual facilitó la manipulación del tejido y el posterior injerto del mismo. Todos los implantes resultaron viables y se pudo comprobar como los injertos con mayor periodo de seguimiento (30 días) se encontraban mejor conformados, con múltiples capas celulares. CONCLUSIONES: Las técnicas de cultivo in vitro de queratinocitos son aplicables a otros epitelios, entre ellos el urinario. En un periodo de tiempo relativamente corto se puede obtener un tejido in vitro tridimensional apto para trasplantar. El estudio histológico puso de manifiesto que el injerto libre de epitelio urinario autólogo cultivado es totalmente viable, apuntando futuras aplicaciones clínicas

OBJETIVE: The purpose of this study is to apply the in vitro keratinocyte culture techniques and the tissue engineering principles to urothelium, to obtain a three-dimensional autologous tissue suitable for grafting. We also showed the viability of free graft cultured urothelium in an experimental model. MATERIAL AND METHODS: An animal experimental model was designed to apply the techniques of cellular culture and tissue engineering. Biopsy specimens of bladder mucosa were obtained, in vitro cultured and posteriorly implanted in each animal. We established three groups based on different follow-up periods (7, 14 and 30 days), and made a final histomorphological study to demonstrate the viability of the graft at the end of its respective follow-up period. RESULTS: A three-dimensional in vitro tissue was obtained, composed of a bio-artificial submucosa (fibrin gel and fibroblast) where the uroepithelial cells were seeding; a biodegradable polyglycolic acid mesh was used to facilitate the tissue manipulation and implantation. In the morphological study all the implants appeared viable, but the grafts with longer implantations periods were better conformed, showing a tisular structure with multiple cellular layers. CONCLUSIONS: In vitro keratinocyte culture techniques could be applied to other epithelial tissues as the urothelium. We obtained a three-dimensional in vitro tissue suitable for grafting in a relatively short time. The histological study demonstrated that free autologous urothelial graft is totally viable, opening future clinics applications

Estado actual de la ingeniería de tejidos en urología. Revisión de la literatura / Current state of the tissue engineering in urology. Revision of the literature

En la década de los 80 surge un nuevo campo de la medicina que aplica los principios del cultivo celular a polímeros sintéticos biodegradables de soporte con el fin de crear sustitutos biológicos autólogos que puedan mejorar, mantener o restaurar la función de órganos o tejidos dañados. La Ingeniería Tisular constituye una nueva disciplina en plena fase de desarrollo, especialmente en USA, con múltiples potenciales aplicaciones en las diferentes especialidades médicas. Nuestra especialidad no puede permanecer ajena al interés y esperanzador futuro suscitado por esta nueva ciencia. En el presente trabajo realizamos una amplia revisión bibliográfica en Medline con objeto de conocer los antecedentes, estado actual y las posibles aplicaciones futuras de la Ingeniería de Tejidos en Urología

The Tissue Engineering constitutes a new discipline in full phase of development especially in USA, with multiple potential applications in several medical specialities. Our speciality can’t remain indifferent to interest and encouraging future originated by this new science. In this work we have made a wide bibliographical revision in the Medline to know the antecedents, current state and the possible future applications of Tissue Engineering in Urology

[Usefulness of abdominal leak point pressure determination in the diagnosis of female urinary incontinence in the TVT era]. / Utilidad de la determinación de la presión abdominal de fuga en el diagnóstico de la incontinencia de orina femenina en la epoca del TVT.

OBJECTIVE: To analyse our results about continence in the treatment of female urinary incontinence with the tension-free vaginal tape (TVT) procedure based on abdominal leak point pressure(ALPP). PATIENTS AND METHODS: Retrospective study of the fifty two patients who had urodynamic study and abdominal leak point pressure determination and were operated on between 1999 and 2002 for stress urinary incontinence. We reviewed the data of clinical history, physical examination and urodynamic report, surgery, complications, and objective and subjective results. Those patients having ALPP > 100 are included in group 1, between 61 and 100 in group 2 and less than 60 in group 3. RESULTS: There were 19 patients in group 1, 17 in group 2 and 16 in group 3. We found no difference between the three groups regarding age, delivery, menopause, hysterectomy, evolution, previous surgery, grade of cystocele, association of anterior colporraphy to TVT and type of anaesthesia. The Obrink clinical grade increased as the ALPP decreased (grade 3 in 26.32% of group 1, 31.58% in group 2 and 68.71% in group 3). 100% of patients in groups 1 and 2 were continent with effort and 93.75% in group 3. Complications, especially de novo instability or urgency-frequency episodes or persistence of instability in patients having mixed incontinence, caused a decrease in the satisfaction degree to 79% in group 1, 76.5% in 2 and 62.5% in 3. CONCLUSIONS: Abdominal leak point pressure determination does not change our decision of perform a TVT procedure but permits us to differentiate one group in which results could be worse.

Utilidad de la determinación de la presión abdominal de fuga en el diagnóstico de la incontinencia de orina femenina en la época del TVT / Usefulness of abdominal leak point pressure determination in the diagnosis of female urinary incontinence in the TVT era

OBJETIVO: Analizar los resultados del tratamiento de la incontinencia de esfuerzo tratada con TVT en función de la presión abdominal de fuga (PAF). MATERIAL Y MÉTODO: Estudio retrospectivo de 52 pacientes operadas entre 1999 y 2002 que tenían estudio urodinámico y determinación de la PAF, con seguimiento mínimo de 3 meses. Se analizan las características clínicas y resultados respecto de la desaparición de la incontinencia al esfuerzo como de la sensación subjetiva y satisfacción de las pacientes. Denominamos grupo 1 si la PAF>100; grupo 2 entre 61 y 100; y grupo 3 si la PAF<60. RESULTADOS: En el grupo 1 había 19 pacientes, 17 en el 2 y 16 en el 3. No existieron diferencias entre los 3 grupos respecto a la edad, paridad, menopausia, histerectomía, años de evolución, cirugía previa, presencia y grado de cistocele, asociación de colporrafia al TVT y tipo de anestesia utilizada. El grado clínico de Obrink aumentó a medida que disminuía la PAF (grado 3 en 26,32% del grupo 1; 31,58% del 2 y 68,71% del 3).La continencia al esfuerzo se consiguió en el 100% de las pacientes de los grupos 1 y 2, y en el 93,75% del grupo 3. La aparición de complicaciones, especialmente inestabilidad de novo o cuadros de urgencia-frecuencia así como la persistencia de inestabilidad en algunos casos de incontinencia mixta, hizo que el grado de satisfacción de las pacientes fuese del 79% en el grupo 1, 76,5% en el 2 y del 62,5% en el 3. CONCLUSIONES: La determinación de la PAF no parece influir en la decisión de implantar un TVT, pero sí permite diferenciar un grupo (PAF<60 cm de agua) cuyos resultados esperados son ligeramente peores

[Upper urinary tract tumours]. / Tumores de urotelio superior.

OBJECTIVE: To evaluate diagnostic techniques, treatment and follow-up in 94 patients affected of upper urinary tract tumor. PATIENTS AND METHOD: From 1978 to december 2002 we operated 105 patients due to upper urinary tract tumor, although only 94 are valid for analysis. Mean age was 65 years and 85% were man. Haematuria was the most frequent symptom. RESULTS: Urography (93%), ecography (77%) and CT (67%) were the most used diagnostic techniques. Pelvic tumor was the most frequent (71%) and total nephroureterectomy including bladder cuff the chosen treatment (76.4%). Previous or simultaneous bladder tumor was observed in 23% cases and delayed in 30%. With a mean follow-up of 76 months the patient survival is 53%. CONCLUSIONS: Due to the high frequence of previous, simultaneous or delayed bladder tumors, the upper urinary tract tumor should be considered as a panurothelial disease, worsening the outcome of this kind of tumors.

Tumores de urotelio superior / Upper urinary tract tumours

OBJETIVOS: Evaluar los métodos diagnósticos empleados, el tratamiento y el seguimiento de los pacientes afectos de tumor de urotelio superior. PACIENTES Y MÉTODO: Desde 1978 hasta diciembre de 2002 han sido operados 105 pacientes afectos de tumor de urotelio superior, siendo válidos para el análisis 94. La edad media ha sido de 65 años, siendo el 85 por ciento varones. La hematuria fue el síntoma más frecuente de presentación. RESULTADOS: Se realizó UIV en el 93 por ciento de los pacientes, la ecografía en el 77 por ciento y el TAC en el 67 por ciento. Predominó el tumor piélico (71 por ciento) y el tratamiento mayoritario fue la nefroureterectomía total con resección del collarete vesical perimeatal (76,4 por ciento). El tumor vesical previo o simultáneo se constató en 22 casos (23,3 por ciento) y posterior en 28 casos (30 por ciento). Con un seguimiento medio de 76 meses, la supervivencia es del 53 por ciento. CONCLUSIONES: El tumor de urotelio superior debe considerarse como una enfermedad panurotelial debido a la alta frecuencia de tumor vesical previo, simultáneo o posterior, lo cual empeora aún más el pronóstico de esta enfermedad (AU)
