Factores pronósticos en cáncer renal con trombo en vena. Análisis de supervivencia / Prognostic factors in renal cancer with venous thrombus survival analysis

OBJETIVO: Analizar el tratamiento quirúrgico en el cáncer renal con trombo venoso a distintos niveles, así como las complicaciones perioperatorias y los diversos factores pronósticos relacionados a supervivencia global, cáncer específica y libre de enfermedad. MÉTODOS: Estudio descriptivo retrospectivo de 42 casos de cáncer renal con trombo venoso entre 2005 y 2015. El nivel alcanzado por el trombo se estableció según la clasificación de la Clínica Mayo. Las complicaciones postoperatorias se estadificaron según la clasificación de Clavien-Dindo. RESULTADOS: Predominio masculino con media de edad de 65,7 años. El 16,6% correspondieron a tumores con trombo de nivel II. En el 58,9% se realizó un abordaje subcostal. En 2 pacientes se estableció hipotermia con parada cardíaca y circulación extracorpórea. En 3 pacientes se realizó resección de lesiones metastásicas durante la nefrectomía radical. La necesidad de reintervención fue del 2,3% mientras que, la mortalidad perioperatoria fue del 4,7%. El 30% debutaron con metástasis al diagnóstico. Veinte pacientes progresaron a 15,5 meses (3-55). La supervivencia global fue de 60 meses. La mortalidad cáncer específica fue del 75%. La supervivencia libre de enfermedad fue del 30% a 55 meses. CONCLUSIONES: El tratamiento quirúrgico del cáncer renal con trombo venoso precisa un manejo multidisciplinar. La técnica quirúrgica seleccionada varía en función del nivel del trombo tumoral. El estadiaje tumoral es el factor pronóstico de mayor importancia. El nivel del trombo influye en el pronóstico, teniendo una supervivencia mayor aquellos pacientes con trombo confinado en vena renal (pT3a) frente a los tumores con trombo en aurícula (pT3c)

OBJECTIVES: To analyze surgery for renal cancer with venous thrombus at different levels, perioperative complications and prognostic factors associated to overall, cancer-specific and disease-free survival. MATERIAL AND METHODS: Retrospective analysis of 42 cases of renal cancer with venous thrombus performed between 2005 and 2015. The level reached by the thrombus was established according to the Mayo Clinic classification. Postoperative complications were staged according to Clavien-Dindo classification. RESULTS: Most frequent in males. Mean age 65.7 years. 16.6% were tumors with level II thrombus. Subcostal approach was performed in 58.9%. Extracorporeal circulation with cardiac arrest and hypothermia was established in 2 patients. Resection of metastatic disease was performed in 3 patients during radical nephrectomy. Reoperation was 2.3% while, perioperative mortality was 4.7%. 30% presented with metastases at diagnosis. Twenty patients progressed at 15.5 months (3-55). Overall survival was 60 months. The cancer-specific mortality was 75%. Disease-free survival was 30% at 55 months.CONCLUSIONS: Surgical treatment of renal cancer with venous thrombus requires a multidisciplinary management. The surgical technique varies according to the level reached by the venous thrombus. Tumor stage is the most important prognostic factor. Thrombus level influences prognosis, with longer survival for patients with tumor thrombus confined to the renal vein (pT3a) in comparison to tumors with thrombus in the atrium (pT3c)

[Small cell carcinoma of the bladder: Our experience]. / CARCINOMA DE CÉLULAS PEQUEÑAS DE VEJIGA.

OBJECTIVES: Small cell carcinoma of the bladder shows low incidence and poor survival; thus, treatment algorithms based on randomized studies are unavailable. The aim of the present study is to review our case series. METHODS: Observational retrospective study of 10 patients diagnosed with small cell carcinoma of the bladder between 2006 and 2013. RESULTS: Mean age was 65.7 years; There was only one female in the cohort. In all cases hematuria was the fist symptom. 4 cases presented high-grade papillary urothelial carcinoma with small cell carcinoma. Radical cystectomy was performed in 40% patients, in combination with chemotherapy, radiotherapy or both. Median survival was 330 days (IC 95%: 40.757- 619.243) and only one patient showed complete response. CONCLUSIONS: Even when small cell carcinoma of the bladder is a low incidence tumor, its prognosis is worse than that of urothelial carcinoma. Although further randomized studies are needed to best define treatment, this study shows that survival at local stages is optimized by neoadjuvant chemotherapy, followed by radical resection, as the literature suggests.

Carcinoma de células pequeñas de vejiga / Small cell carcinoma of the bladder: Our experience

OBJETIVO: El carcinoma vesical de células pequeñas presenta una baja incidencia y escasa supervivencia, por lo que no existen esquemas terapéuticos basados en estudios randomizados. Nos planteamos como objetivo revisar nuestra casuística. MÉTODOS: Estudio observacional retrospectivo de 10 pacientes diagnosticados de carcinoma de células pequeñas entre 2006 y 2013. RESULTADOS: La edad media fue de 65,7 años y sólo se presentó en una mujer de los 10 pacientes. Se relacionó en su totalidad con antecedentes de tabaquismo, siendo la forma de presentación la hematuria. 4 casos presentaban carcinoma urotelial de alto grado junto con el componente microcítico. Se realizó cistectomía radical en el 40% de los pacientes, recibiendo además tratamiento con quimioterapia, radioterapia o ambos. La mediana del tiempo de supervivencia fue de 330 días (IC 95%: 40,757 - 619,243). Sólo en un caso obtuvimos respuesta completa. CONCLUSIONES: El carcinoma de células pequeñas de vejiga es un tumor con baja incidencia pero de peor pronóstico que los tumores uroteliales. Aunque se necesiten más estudios randomizados para definir el mejor tratamiento, y nuestra casuística sea limitada, se ha publicado que los mejores resultados en cuanto a supervivencia en los estadios localizados se consiguen con quimioterapia neoayuvante seguida de cirugía radical

Urinary incontinence during pregnancy and postpartum. Associated risk factors and influence of pelvic floor exercises.

OBJECTIVES: To determine the prevalence of urinary incontinence (UI) before pregnancy, in the third trimester and postpartum. To analyze its influence on quality of life and associated potential risk factors and the efficacy of pelvic floor exercises. METHODS: Prospective study in 413 pregnant women. The modified ICIQ-SF incontinence questionnaire was given to the pregnant women at the end of the third quarter. This questionnaire was administered by telephone at 3 and 6 months postpartum. The influence of several risk factors for UI in pregnancy and postpartum were analyzed. Patients with persistent UI at 6 months postpartum were trained to do pelvic floor exercises. RESULTS: Patients with UI before pregnancy were excluded from the study. UI in the third trimester was 31%. Analyzed risk factors did not condition a higher percentage of UI. Prevalence of UI was 11.3% at 3 months postpartum and 6.9% at 6 months. 70% of the incontinent patients already had it during pregnancy and it appeared de novo post-delivery in 30% of the patients. Prevalence of UI after delivery was higher in women with UI in pregnancy and lower in caesarean cases. Most women improved with pelvic floor exercises. CONCLUSIONS: Analysed risk factors did not significantly increase UI in pregnancy. Prevalence of UI after delivery is higher in women with UI in pregnancy and lower in caesarean cases. Postpartum pelvic floor exercises for three months in patients with persistent stress UI at 6 months postpartum clearly improved the degree of continence.

Incontinencia urinaria en embarazo y postparto. Factores de riesgo asociados e influencia de los ejercicios del suelo pélvico / Urinary incontinence during pregnancy and postpartum. Associated risk factors and influence of pelvic floor exercises

OBJETIVO: Determinar la prevalencia de incontinencia urinaria (IU) previa a la gestación, en el tercer trimestre y en el postparto. Analizar su influencia en la calidad de vida, los posibles factores de riesgo y la eficacia de los ejercicios del suelo pélvico. MÉTODOS: Estudio prospectivo a 413 gestantes. Se entregó el cuestionario de incontinencia ICIQ-SF modificado a las gestantes al final del tercer trimestre y a los 3 y 6 meses postparto. Se analizó la influencia de varios factores de riesgo de IU en el embarazo y en el postparto. Las pacientes con persistencia de IU a los 6 meses del parto fueron instruidas para realizar ejercicios de suelo pélvico. RESULTADOS: Las pacientes con IU previa a la gestación fueron excluidas. La prevalencia de incontinencia en el tercer trimestre en gestantes fue del 31%. Ningún factor de riesgo condicionó un mayor porcentaje de IU. La prevalencia de IU fue de 11.3 % a los tres meses del parto y del 6.9% a los 6 meses. De las pacientes incontinentes un 70% ya la sufría en el embarazo y en el 30% apareció de novo tras el parto. El porcentaje de IU postparto fue más elevado en mujeres con IU en la gestación y más bajo en aquellas con cesárea. La mayoría de las mujeres mejoraron con ejercicios de suelo pélvico. CONCLUSIONES: Ningún factor de riesgo aumenta el riesgo de IU en gestantes de forma significativa. La prevalencia de IU tras el parto es mayor en aquellas mujeres con IU en el embarazo y más baja en aquellas con cesárea. La mayoría de las puerperas mejoraron con ejercicios de suelo pélvico

Indicaciones y complicaciones de la embolización renal: análisis retrospectivo / Indications and complications of renal embolization: a retrospective analysis

La embolización renal es un procedimiento intervencionista, cuyas aplicaciones terapéuticas han variado a lo largo del tiempo. Realizamos una revisión retrospectiva de 48 embolizaciones, analizando las causas y complicaciones asociadas a esta técnica. Nuestra indicación principal fue la embolización prequirúrgica de tumores renales de gran tamaño, aunque la indicación de mayor relevancia clínica actual es el tratamiento conservador de fístulas arterio-venosas iatrogénicas, angiomiolipomas o traumatismos renales con sangrado activo. La complicación menor más frecuente es el síndrome post-embolización (52.8 por ciento), situación que remite fácilmente con tratamiento médico. Como complicaciones mayores destacan la sepsis y la migración de material embolígeno, ambos muy poco frecuentes en nuestra serie...

Renal embolization is an interventional procedure, whose therapeutic applications have varied over time. We conducted a retrospective review of 48 embolizations, analyzing the causes and complications associated with this technique. Our main indication was the preoperative embolization of large renal tumors, although the most relevant indication today is the conservative treatment of iatrogenic arteriovenous fistula, angiomyolipomas or renal trauma with active bleeding. The most common minor complication is post-embolization syndrome (52.8 percent), a situation that is easily managed with medical treatment. Major complications include sepsis and migration of embolic material and both are very rare in our series...

Fibrous pseudotumor affecting the tunica vaginalis, epididymis and seminal duct.

OBJECTIVE: To report one case of advanced fibrous pseudotumour. METHODS: A 34-year-old patient presented with a painless lump on the right side of the scrotum. Examination revealed a hard tissue thickening attached to the tail and body of the right epididymis. The results of the ultrasound study were not clear and multiple differential diagnosis were considered. The lesion was surgically removed by partial right epididymectomy and resection of the affected tunica vaginalis and ductus deferens for anatomopathological study. RESULTS: The histopathological study revealed an evolved fibrous pseudotumour with bone metaplasia. CONCLUSION: Fibrous pseudotumour is a benign paratesticular lesion that grows slowly and painlessly. It is usually diagnosed by chance or in associated processes such as hydrocele. Differential diagnosis with malignant tumors avoids unnecessary radical treatment.

Pseudotumor fibroso que afecta a la túnica vaginal, el epidídimo y la vía seminal / Fibrous pseudotumor affecting the tunica vaginalis, epididymis and seminal duct

OBJETIVO: Presentamos un caso evolucionado de Pseudotumor fibroso. MÉTODOS: Varón de 34 años que consulta por bultoma escrotal derecho indoloro presentando a la exploración un engrosamiento de consistencia indurada fusionado a la cola y el cuerpo de epidídimo derecho. El estudio ecográfico no fue aclaratorio planteando múltiples diagnósticos diferenciales. Se realizó exéresis de la lesión precisando una epididimectomía parcial derecha y resección de la túnica vaginal y el conducto deferente afectados para su estudio anatomopatológico. RESULTADOS: El estudio histopatológico de la pieza quirúrgica correspondía a un pseudotumor fibroso evolucionado, con metaplasia ósea. CONCLUSIÓN: El pseudotumor fibroso es una lesión paratesticular benigna, de crecimiento lento e indoloro. El diagnóstico suele ser por hallazgo casual o por procesos asociados como el hidrocele. El diagnóstico diferencial con los tumores malignos evita tratamientos radicales innecesarios (AU)
