ABSTRACT

OBJECTIVE: We present the case of a patient diagnosed with a testicular extramedullary plasmacytoma (EMP), and perform a brief review of the literature of this pathology. METHODS: A 64 year-old male patient, with history of multiple myeloma successfully treated three years before, presented with left testicular swelling. Initial work-up was compatible with a testicular tumor and radical inguinal orchiectomy was performed. RESULTS: Histologic examination of the testis revealed extensive intertubular infiltration by CD138 and CD56 atypical plasma cells, with diffuse staining for IgA, compatible with EMP. CONCLUSIONS: Invasion of the testis in multiple myeloma patients as a recurrence of the disease is an extremely rare condition, as EMPs are more common in other organ systems. Initial treatment should be the same as a primary testicular tumor with radical inguinal orchiectomy, and definitive diagnosis is established in histologic analysis.

Objectivo: Presentamos un caso de un paciente diagnosticado de un plasmocitoma extramedular testicular, y realizamos una breve revisión de la literatura de esta patología. Métodos: Un paciente varón de 64 años de edad, con antecedente de mieloma múltiple tratado exitosamente hace 3 años, se presenta con hinchazón testicular izquierda. El manejo inicial es compatible con un tumor testicular y se realiza orquiectomía radical inguinal. Resultados: Análisis histológico de la pieza reveló una infiltración intertubular extensa por células plasmáticas atípicas CD138 y CD56, con tinción difusa para IgA, compatible con plasmocitoma extramedular. Conclusiones: La invasión testicular en pacientes con mieloma múltiple como una recurrencia de la enfermedad es una condición extremadamente rara, ya que los plasmocitomas extramedulares son más frecuentes en otros órganos. El tratamiento inicial debe ser igual que si se tratase de un tumor testicular primario, y el diagnóstico definitivo se establece mediante análisis histológico (AU)

ABSTRACT

OBJETIVE: Our aim is to present a novel mutation of the Birt-Hogg-Dubé Syndrome. METHODS: We present a case report of a 70-year-old male with three solid nodulary lesions of 4, 2.6, and 3 cm each in the right kidney, and two lesions of 1.5 and 1.3 cm in the left kidney. RESULTS: Needle biopsy was performed. The pathological analysis of right kidney lesions revealed a renal tumor suggestive of chromophobe renal cell carcinoma and medullar tumor with zones that suggested oncocytosis. Genetic test results were positive for a novel heterozygous mutation c.1198G>A; p.V400I in exon 11 of the FLCN gene. CONCLUSION: In patients presenting with bilateral multifocal renal tumors of oncocytic hybrid histology, Birt- Hogg-Dubé syndrome should be the first diagnosis in mind. The mutation found in this patient has not been previously described in the literature in the context of BHD.

ABSTRACT

INTRODUCTION: In the last 15 years, the role of laparoscopic surgery has progressively increased to include reconstructive procedures such as pyeloplasty and management of ureteral stricture, in addition to being a field in continuous development, this refers to the improvement of ergonomics, new instruments and new techniques. We present a review on basic features of laparoscopic reconstructive surgery in urology. ACQUISITION OF EVIDENCE: For this review, an exhaustive literature search was performed in PUBMED, MEDILNE, BioMed central and others, with the keywords: reconstructive surgery, urology, laparoscopy. Only articles including urologic procedures in the adult and published in the last 6 years, were selected for this review. SYNTHESIS OF EVIDENCE: One of the objectives of any urological reconstructive procedure is to treat any segment of the genitourinary tract that is obstructed due to scar tissue following trauma or iatrogenic causes. After the excision of such segment or scar, a mobilization of the 2 healthy extremities of the urinary tract must be performed in order to proceed with a tension-free anastomosis. Occasionally, if there is tension, a mobilization of the organs at each side of the lesion should be performed to reduce the tension of the anastomosis; also, it should be a water-tight anastomosis to ensure good functional results. Another type of procedure is to perform laparoscopic repair surgery of pelvic organ prolapse in which the vaginal anatomy should be adequately restored, with good function maintained (sexual, urinary, intestinal) and durability. CONCLUSIONS: With the worldwide expansion of minimally invasive surgery in the area of laparoscopy and robotics, it has been possible to reproduce many of the reconstructive techniques that have followed the evolutionary course of surgery from the open to the robot assisted technique, which has made clear that such therapeutic options exist and are reproducible with good results.

ABSTRACT

INTRODUCCIÓN: En los últimos 15 años, el papel de la laparoscopia ha aumentado progresivamente para incluir la realización de procedimientos reconstructivos como la pieloplastia y el manejo de estenosis ureteral, además de ser un campo que se encuentra en continuo desarrollo, esto se refiere a la mejora de la ergonomía, nuevos instrumentos y nuevas técnicas. Presentamos una revisión sobre aspectos básicos de la cirugía reconstructiva laparoscópica en urología. Adquisición de la evidencia: Para esta revisión se realizó una búsqueda exhaustiva de literatura en los buscadores PUBMED, MEDILNE, BioMed central entre otros con las palabras clave: cirugía reconstructiva, urología, laparoscopia. Se seleccionaron para esta revisión artículos que incluyeran procedimientos urológicos en el adulto y publicados en los últimos 6 años. Síntesis de la evidencia: Uno de los objetivos de cualquier procedimiento reconstructivo urológico es el de tratar algún segmento del aparato genitourinario que se encuentra obstruido debido a tejido cicatricial posterior a un traumatismo o por causa iatrogénica. Después de la escisión del segmento o cicatriz, se debe realizar una movilización de los 2 extremos sanos para proceder a la realización de una anastomosis libre de tensión. Ocasionalmente, si hay tensión se debe realizar una movilización de los órganos que se encuentran en cada extremo de la lesión para reducir la tensión de la anastomosis; a su vez debe ser una anastomosis estanca para asegurar los buenos resultados funcionales de la misma. Otro tipo de procedimiento es el de realizar cirugía reparadora laparoscópica en el prolapso de órganos pélvicos en la cual se debe restaurar adecuadamente la anatomía vaginal, mantener la función (sexual, urinaria, intestinal) y durabilidad. CONCLUSIONES: Con la expansión a nivel mundial de la cirugía mínimamente invasiva en el área de laparoscopia y robótica se ha logrado reproducir muchas de las técnicas reconstructivas que han seguido el curso evolutivo de la cirugía desde la técnica abierta hasta la asistida por robot, lo que ha dejado claro que dichas opciones terapéuticas existen y son reproducibles con buenos resultados

ABSTRACT

Objectives: To evaluate the results of erectile function rehabilitation with sildenafil after laparoscopic radical prostatectomy (LRP). Materials and methods: We have evaluated on a retrospective way a subgroup of LRP with neurovascular bundles sparing that have followed a treatment schedule for erectile function rehabilitation based on sildenafil citrate. We defined the initial erectile function state as penetrate without drugs, with drugs and do not penetrate. A comparison with the erectile function after the treatment was performed. Data were analyzed at our biostatistics section. Results: We selected a total of 33 patients, 7 with unilateral neurovascular bundles sparing and 26 with bilateral neurovascular bundles sparing treated with sildenafil citrate after surgery. The recuperation rate of erectile function with bilateral sparing was 80.7%. This success rate reaches 87.5% in patients <70 years old. In the unilateral sparing group the success rate was 85.7%. Two patients abandoned the treatment schedule. Conclusions: Laparoscopic radical prostatectomy with neurovascular bundles sparing offers a high preservation rate of erectile function on expert surgeons. The maintenance treatment with phosphodiesterase-5 inhibitors may offer benefits for the erectile function rehabilitation and it has to be initiated as soon as possible. (AU)


Objetivos: Evaluar los resultados de la rehabilitación de la función eréctil con sildenafilo tras prostatectomía radical laparoscópica (PRL). Material y Metodos: Hemos evaluado de forma retrospectiva un subgrupo de PRL con preservación de haces neurovasculares que han seguido una pauta de tratamiento para la rehabilitación de la función sexual con citrato de sildenafilo. Se ha definido el estado basal de la función eréctil como “penetra sin fármacos”, “penetra con fármacos” y “no penetra”. Se compararon los resultados antes y después del tratamiento. Los datos fueron analizados en nuestra sección de bioestadística. Resultados: Se han seleccionado un total de 33 pacientes, 7 con preservación unilateral de haces neurovasculares y 26 con preservación bilateral. La tasa de recuperación de la función eréctil con preservación bilateral es del 80.7%. Esta tasa alcanza el 87.5% en pacientes < de 70 años. Para el grupo de preservación unilateral la tasa es de 85.7%. Dos pacientes han abandonado la terapia. Conclusiones: La PRL con preservación de erectores ofrece una elevada tasa de conservación de la función eréctil cuando es llevada a cabo por cirujanos expertos. La terapia mantenida con iPDE5 puede ofrecer beneficios para la rehabilitación de la función eréctil y debe administrarse lo antes posible (AU)

ABSTRACT

INTRODUCTION: It is not unusual for bladder tumors to appear following transitional cell carcinoma of the upper urinary tract (UUT), with involvement of the UUT, following invasive bladder cancer, being less common. The synchronous presence of transitional cell carcinoma of the bladder and of the UTT is exceptional. METHODS: Fifteen simultaneous cystectomies with nephroureterectomies were performed due to synchronous UUT and invasive bladder cancers (1997-2009). Surgery was performed using an open approach in 10 patients, while the last 5 procedures were performed laparoscopically. RESULTS: The mean age was 68.7 years. Mean surgery time was 348.6 minutes. Mean blood loss was 816 ml. Acute renal failure was the most frequent postoperative complication being present in 5 patients (33%). There was 1 case of a leak in the ureter-intestinal anastomosis (open approach), which required placement of a left-sided percutaneous nephrostomy. There were 2 cases of postoperative mortality, both in the open approach series and with intestinal neobladder. Mean follow-up time for the whole series was 21.25 months. Eight cases experienced metastatic progression of the disease (mean follow-up 17 months). CONCLUSION: Though multi-site studies with longer follow-up and a greater numbers of patients are needed, the moment at which urothelial tumors appear seems to influence their prognosis, with lower survival rates for tumors that synchronically appear.

ABSTRACT

INTRODUCTION: The retroperitoneal surgery is the clearer indication for the laparoscopic approach. Still there are indications for open surgery because of the complexity of the patient and the surgeon experience. OBJECTIVES: The main objective is to report our experience of laparoscopic radical nephrectomies in patient with tumors greater than 7 cm. or surgical specimens with more than 700 g of weight. We analyze their characteristics, complications rate, surgical time, postoperative outcome and hospital stay. MATERIALS AND METHODS: Since July 2004 to July 2008 we have performed 104 laparoscopic radical nephrectomies. We have selected 41 patients with characteristics of big surgical specimens. RESULTS: The average surgical time has been of 184,3 min. Only 1 case has been converted into open surgery and only 1 intraoperative death because of cardiologic arrhythmia. The average hospital stay has been of 3,51 days. The complications rate and postoperative outcome are similar to the whole series. DISCUSSION: Laparoscopic nephrectomy is technically less complex than radical prostatectomy. However, their possible complication implies a much bigger severity. The more complex cases must be approach laparoscopically only after a wide experience. Actually, in our department we usually indicate an open approach when surgical specimen crossover the abdominal middle line and in those cases where the tumoral thrombus affect the main renal vein and/or the vena cava.

ABSTRACT

Surgery is the treatment of choice for clear cell renal carcinoma not responding to chemotherapy, radiotherapy, or immunotherapy. The surgical procedure used has evolved over time in the past 40 years, mainly because of the development and widespread use of diagnostic procedures such as ultrasonography and CT. As a direct consequence, parenchymal-sparing surgery was no longer only used for patients with solitary kidneys and its indication started to be extended to patients with tumors up to 4 cm in diameter, in whom it has been shown to be a safe and effective alternative to radical nephrectomy. The other important milestone in development of renal cancer surgery undoubtedly was the revolution started in the 90s with advent of laparoscopic renal surgery, which has become established over the past 20 years approximately. Laparoscopic surgery initially raised concern about oncological safety, but clinical series with sufficiently long follow-up times and large sample sizes are now available to consider the laparoscopic approach as a reliable procedure. Technological development has caused the laparoscopic technique to be no longer seen as a procedure for the future, but rather as an absolutely current technique which should be implemented in most urology departments. Implementation of any new procedure usually involves a number of complications which we should be prepared to assume, while making every effort to try and prevent them. It is therefore essential to develop, and to implement using common sense, a training program on the procedure. Selection of patients and conditions to be treated is a crucial part of such a program.

ABSTRACT

Introducción: La cirugía retroperitoneal constituye la indicación más indiscutible para el abordaje laparoscópico. Todavía persisten indicaciones de cirugía abierta en función de la complejidad del caso y de la experiencia del cirujano. Objetivos: El objetivo principal es comunicar nuestra experiencia de nefrectomía radical laparoscópica en pacientes con tumores ≥7 cm o con piezas quirúrgicas cuyo peso haya sido ≥700 g. Analizaremos sus características, la tasa de complicaciones intraoperatorias, el tiempo quirúrgico, el curso postoperatorio así como la estancia postoperatoria. Material y métodos: Desde julio del 2004 hasta julio del 2008 hemos realizado un total de 104 nefrectomías radicales laparoscópicas. Hemos seleccionado un subgrupo de 41 pacientes con criterios de pieza quirúrgica de gran tamaño. Resultados: El tiempo quirúrgico medio ha sido de 184,3 minutos. Hemos tenido un caso de reconversión a cirugía abierta y un fallecimiento intraoperatorio por causa cardiológico. La estancia media global ha sido de 3,51 días. La tasa de complicaciones y el curso postoperatorio son comparables a toda la serie. Discusión: La nefrectomía laparoscópica es técnicamente menos compleja que la prostatectomía radical laparoscópica. Sin embargo, sus posibles complicaciones entrañan una gravedad mucho mayor. Los casos más complejos han de ser abordados por vía laparoscópica sólo cuando existe una dilatada experiencia. En general, en nuestro centro relegamos a cirugía abierta las piezas que sobrepasan la línea media y los casos con trombo tumoral que afecte a la vena renal principal y a la VCI (AU)

ABSTRACT

El tratamiento de elección del carcinoma renal de células claras es un tratamiento quirúrgico, siendo un tumor que no responde a quimioterapia, radioterapia o inmunoterapia. Dicho tratamiento quirúrgico ha ido variando a lo largo del tiempo en los últimos 40 años, debido sobre todo al desarrollo y universalización de los sistemas de diagnóstico como la ecografía y la TAC. Como consecuencia directa, la cirugía conservadora de parénquima deja de ser empleada solamente en pacientes monorrenos y comienza a extenderse sus indicaciones en pacientes con tumores de hasta 4 cm de diámetro, demostrando ser una alternativa segura y eficaz a la nefrectomía radical. El otro hito importante en el desarrollo del tratamiento quirúrgico del cáncer renal es sin duda la revolución iniciada en la década de los 90 con el inicio de la cirugía renal laparoscópica, que ha venido implantándose en los últimos 20 años aproximadamente. En unos comienzos dubitativos en lo que a seguridad oncológica se refiere, actualmente contamos con series lo suficientemente extensas en tiempo de seguimiento y tamaño muestral, como para pensar que se trata de una técnica lo suficientemente fiable. El desarrollo de la tecnología ha ayudado a que la técnica laparoscópica ya no se vea como una técnica de futuro, sino de absoluta actualidad que debería estar implantada en la mayoría de los servicios de Urología. Toda implantación de una nueva técnica suele acarrear una serie de complicaciones que debemos estar dispuestos a asumir y a intentar poner todos los medios a nuestro alcance para evitarlas. Ante esta situación, es fundamental desarrollar un programa de formación y de inicio en la técnica llevado a cabo con sentido común, en el cual la selección de los pacientes y de las patologías a abordar es primordial (AU)

ABSTRACT

OBJECTIVES: The main challenge of laparoscopic nephroureterectomy is the management of distal ureter, which also will have an important repercussion in the oncological outcome of many cases. We present our experience in such aspect, considering that we performed the last five laparoscopic nephroureterectomies in forced Trendelemburg position, resulting in a more comfortable and safe management of the distal ureter. METHODS: Between August and December 2006 we performed five purely laparoscopic nephroureterectomies with bladder cuff positioning the patient in forced Trendelemburg, a position similar to that of laparoscopic radical cystectomy or prostatectomy. RESULTS: Mean surgical time was 182 minutes (170-210). Mean blood loss was 100 cc and no patient required transfusion. Mean hospital stay was four days. CONCLUSIONS: We believe this position is a good alternative for the management of the distal ureter during the laparoscopic approach. The technique is very similar to open surgery, which continues being the gold standard today.

ABSTRACT

Objetivo: El principal reto de la nefroureterectomía laparoscópica es el manejo del uréter distal que además tendrá una repercusión importante en el resultado oncológico en muchos de los casos. Presentamos nuestra experiencia en este aspecto, teniendo en cuenta que las 5 últimas nefroureterectomías laparoscópicas las hemos realizado con una posición de Trendelemburg forzado, lo que ha supuesto un manejo más cómodo y seguro del uréter distal. Métodos: Desde agosto hasta diciembre de 2006 se han realizado 5 nefroureterectomías con rodete vesical puramente laparoscópico con el paciente en posición de Trendelemburg forzado, muy similar a la posición empleada en las cistectomías o prostatectomías radicales laparoscópicas. Resultados: El tiempo quirúrgico medio es de 182 minutos (170-210). El sangrado medio intraoperatorio es de 100cc y ninguno de estos pacientes ha precisado transfusión. El tiempo hospitalario medio es de 4 días. Conclusiones: Creemos que esta posición es una buena alternativa para el manejo del uréter distal en el abordaje laparoscópico. Se trata de una técnica muy similar a la cirugía abierta, que hoy por hoy continúa siendo el gold Standard (AU)


Objectives: The main challenge of laparoscopic nephroureterectomy is the management of distal ureter, which also will have an important repercussion in the oncological outcome of many cases. We present our experience in such aspect, considering that we performed the last five laparoscopic nephroureterectomies in forced Trendelemburg position, resulting in a more comfortable and safe management of the distal ureter. Methods: Between August and December 2006 we performed five purely laparoscopic nephroureterectomies with bladder cuff positioning the patient in forced Trendelemburg, a position similar to that of laparoscopic radical cystectomy or prostatectomy. Results: Mean surgical time was 182 minutes (170-210). Mean blood loss was 100 cc and no patient required transfusion. Mean hospital stay was four days. Conclusions: We believe this position is a good alternative for the management of the distal ureter during the laparoscopic approach. The technique is very similar to open surgery, which continues being the gold standard today (AU)

ABSTRACT

OBJECTIVE AND METHODS: We report two new cases of this rare and aggressive tumour; one case appeared in the earliest age reported in the literature (case #2). We also review etiological, diagnostic and therapeutic features. RESULTS: Despite aggressive surgery and adjuvant chemotherapy it has a very poor prognosis, with disease progression within 6 months in both cases. CONCLUSIONS: Sarcomatoid renal cell carcinoma is an infrequent entity, extremely aggressive and requires radical surgery at the time of diagnosis due to its advanced stage, although results are poor. It can also appear in young people with the same aggressiveness than in adult age.

ABSTRACT

Objetivo y Métodos: Bajo el formato de casos clínicos aportamos dos nuevos casos de este raro y agresivo tumor, siendo la edad de presentación de uno de ellos (caso clínico nº 2) la más temprana recogida en la literatura. Asimismo, revisamos aspectos relativos a la etiología, diagnóstico y tratamiento. Resultados: A pesar de cirugía muy agresiva y tratamiento adyuvante, el pronóstico es infausto, con progresión de la enfermedad en los primeros 6 meses en ambos casos. Conclusiones: El carcinoma sarcomatoide de riñón es una entidad infrecuente, extremadamente agresiva y que requiere cirugía radical debido a su avanzado estado en el momento del diagnóstico, aunque con pobres resultados. Puede aparecer también en la juventud con la misma agresividad que en la edad adulta Carcinoma renal sarcomatoide. Regresión espontánea. Patología del tumor renal (AU)

ABSTRACT

OBJETIVOS: Analizar los resultados obtenidos en los 2 primeros años de implantación de una vía clínica para la resección transuretral (RTU) de neoformaciones vesicales diseñada en el Hospital Universitario La Paz. MÉTODOS: Hemos diseñado para la resección transuretral de vejiga una vía clínica de 4 estancias hospitalarias (5 días), y que incluye la siguiente documentación: matriz-verificación, órdenes de tratamiento, verificación de variaciones, hoja de información iconográfica para el paciente y la encuesta de satisfacción del paciente. La información para la evaluación de resultados se ha obtenido de la documentación de la vía y de los datos de actividad del Servicio de Urología. Para valorar los resultados en la eficiencia en el consumo de recursos, se ha realizado una comparación entre la estancia media de los pacientes en vía clínica y un grupo control compuesto por una muestra aleatoria de 50 pacientes sometidos a RTU vesical durante 1997 (AU)

ABSTRACT

OBJETIVO: El papiloma invertido urotelial supone el 2,2 por ciento de todas las neoplasias uroteliales. Su significado oncológico aún es incierto, no conociéndose bien su potencial de recidiva y/o progresión. Analizamos nuestra experiencia entre los años 1976 y 1999. MÉTODOS: Entre 1976 y 1998 han sido tratados en nuestro Servicio 31 pacientes con papiloma invertido urotelial del tracto urinario inferior. 17 pacientes presentaron asociación con carcinoma urotelial previo y/o sincrónico (Grupo I) mientras que los otros 14 pacientes presentaron papilomas invertidos primarios (Grupo II). Hemos calculado las tasas de recurrencia y de progresión de forma global y en cada uno de los grupos, realizando una comparación de la frecuencia de entre ambos grupos. 2 pacientes, una del Grupo I y otra del Grupo II, no acudieron a ninguna revisión. El seguimiento medio en los otros 29 casos fue de 51,3 meses (rango 3-125 meses). RESULTADOS: 12 pacientes (41,4 por ciento) presentaron una recurrencia en forma de carcinoma vesical. 10 fueron pacientes del Grupo I (10/16; 62,3 por ciento) y 2 del Grupo II (2/ 13; 15,4 por ciento) (p<0,05). El tiempo medio hasta la recurrencia fue de 17,9 meses (rango 3-58 meses). El tiempo libre de enfermedad resultó mayor en el Grupo II (p<0,05). Se produjo progresión a tumor infiltrante en 3 pacientes, todos con carcinoma vesical superficial asociado (Grupo I). El tiempo medio hasta la progresión fue de 30,7 meses (rango 18-38 meses). No hubo diferencias estadísticamente significativas en el porcentaje de progresión entre los pacientes de los Grupos I y II. CONCLUSIONES: El papiloma invertido de tracto urinario inferior ha presentado, en nuestra serie, una elevada frecuencia de asociación a carcinoma urotelial, así como una alta tasa de recurrencia, aún en el caso de tumores primarios. Esto nos obliga a considerarlo como una neoplasia de bajo grado de malignidad que debe ser sometida a un seguimiento periódico (AU)
