    Full Text Available El ameloblastoma es un tumor de epitelio odontogénico, caracterizado por la invasión local y aumento de la tasa de recidiva. Por esto se realizó este estudio descriptivo para determinar el comportamiento de los ameloblastomas en nuestro medio. Método: estudio retrospectivo de 17 años basado en los datos existentes de los archivos del Departamento Oral de Patología. Se analizaron los archivos de pacientes de enero de 1992 a mayo de 2009, con un diagnóstico definitivo de ameloblastoma. Fué recogida la información respecto al sexo, raza, presencia de síntomas, ubicación anatómica y extensión. Resultados: dentro de los 60 pacientes con ameloblastoma se observó, mayor incidencia en la tercera década de vida (28,3 %. Las mujeres fueron más comprometidas que los hombres, con una proporción 1,22:1. La mayoría de lesiones fueron observadas en la raza blanca (51,7 %. El sitio más habitual por la ocurrencia de tumor fue la mandíbula (85 %. Los pacientes fueron sintomáticos en el 75 %. La mayoría de pacientes presentaron lesiones de 3,5 a 6,0 centímetros de extensión (55 %. Conclusiones: el ameloblastoma es mayormente observado en mujeres, en la tercera década de la vida y en la mandíbula. Las diferencias con otros estudios entre el sexo, la edad, raza, extensión, localización anatómica y los síntomas pueden ser atribuidos a las diferencias geográficas.

    Full Text Available La litiasis renal es causa de importante morbilidad y costo económico, afectando hasta el 15% de la población. Además, la litiasis renal puede ser expresión también de enfermedades extrarrenales, entre las cuales destaca riesgo aumentado de osteoporosis. Estudios nacionales muestran que las causas de litiasis renal en Chile son similares a las comunicadas internacionalmente, destacando la hipercalciuria idiopática como el principal factor de riesgo. A pesar de los avances en técnicas urológicas de remoción de cálculo, éstas no modifican la historia natural de la litiasis renal. Así, en los pacientes sin tratamiento médico, la recurrencia es la regla más que la excepción. En esta revisión se actualiza el estudio y manejo endocrinológico de la litiasis renal, para el cual la evidencia muestra que éste es eficaz y seguro en la prevención de recurrencia de litiasis renal y control de enfermedades asociadas, complementando así el manejo urológico de esta importante enfermedad.

    Full Text Available Background and aims: the management of acute hepatitis C (AHC is controversial. We have conducted a retrospective study to determine the epidemiological and biochemical aspects, the genotypes, the spontaneous clearance of HCV (SVC, and the treatment responses in patients with AHC. Methods: we have retrospectively collected data from 131 patients with AHC from 18 Spanish hospitals. Results: the mean age was 43 ± 16 years (17-83, 69% were symptomatic. The causes of infection were nosocomial in 40% and intravenous drug users in 20%. Eighty two percent had genotype 1. The delay from symptoms-onset to HCV-RNA confirmation was 50 ± 68 days (range, 11-350 days and to treatment (in 59% 14 ±13 weeks (range, 2-58 days. In the treated group, 80% achieved sustained virological response (SVR versus 57% SVC in untreated patients (p = 0.004. Up to 96% of those treated within the first 12 weeks had SVR versus 86% of those treated later (p = 0.04. Patients with HCV-RNA(- at week 4 resolved with or without treatment more frequently than those HCV-RNA(+ (98 versus 69%, p = 0.005. The treatment was not beneficial if HCV-RNA was undetectable at week 12. No differences in SVR were found in genotype 1 patients treated for 24 or 48 weeks. Patients with low baseline viral load achieved higher SVC and SVR. The SVC in patients with bilirubin > 5 mg/dl was 78 versus 40% in those with lower values (p = 0.004. Conclusions: the most common transmission route was nosocomial. SVR was higher in patients treated than SVC in non-treated. Early treatment (before week 12 achieved the highest response rate. SVC and SVR were more common in patients with a low baseline viral load. Undetectable HCV-RNA at week 4 was associated with high SVR and SVC rates. Jaundice was related with SVC.Introducción y objetivos: el manejo de la hepatitis aguda C (HAC es objeto de controversia.

Este estudo tem como objetivo avaliar a incidência de pacientes com mais de 80 anos submetidos à cirurgia cardíaca no Instituto do Coração do Hospital das Clínicas da FMUSP, nos últimos 16 anos. MÉTODO: Foram analisados, no período de 1986 a 2001, o número de cirurgias de revascularização do miocárdio (RM e cirurgia valvar (CV e, em cada grupo, o número de cirurgias em pacientes com mais de 80 anos. Os dados foram analisados descritivamente. RESULTADOS: Os dados revelam aumento progressivo do número de octogenários submetidos à cirurgia cardíaca. As cirurgias de revascularização do miocárdio tiveram aumento de 0,13% em 1986 para 3,5% em 2001. As cirurgias valvares aumentaram de 0% em 1986 para 1,44% em 2001, registrando o maior valor de 3,02% em 1999. CONCLUSÕES: Os conhecimentos da fisiopatologia, da senilidade e os avanços no manuseio do trauma cirúrgico estão permitindo estender os recursos da cirurgia cardíaca no grupo de paciente mais idoso. A escolhas da técnica anestésica deve ser criteriosa, bem como a hidratação, a assistência ventilatória e a analgesia pós-operatória, permitindo redução da morbimortalidade neste grupo de maior risco cirúrgico.JUSTIFICATIVA Y OBJETIVOS: El aumento de la expectativa de vida hace con que pacientes cada vez mas edosos tengan indicación de tratamiento quirúrgico de cardiopatias.

    To obtain mean angulation values for renal hila in relation to the horizontal plane traced over the right and left spinal erector muscles, considering the center of the lumbar vertebral spine as a parameter for measuring the renal hila angles. The authors have analyzed 250 abdominal computed tomography studies of both male and female healthy individuals (128 men with mean age 52.45 {+-} 17.42 years, and 122 women with mean age 54.39 {+-} 18.27 years), corresponding to 500 renal hila evaluated. The mean angulation of each hilum in relation to the horizontal plane was obtained taking acute angles into consideration. The comparative study have not found any statistically significant difference in acute angles of renal hila between male and female individuals. The statistical analysis demonstrated limits of 40.40 deg and 44.54 deg for mean right hilum angulation and 39.91 deg and 43.23 deg for mean left hilum angulation, with a confidence interval of 95% . Renal hila present similar angulation independently of sex. Higher angulation values correspond to hyper-rotation or excessive rotation, and lower angulation values, to incomplete or reverse rotation. (author)

    Full Text Available Gastrointestinal endoscopy is a safe, efficient technique with minimal complications, and a useful diagnostic tool for the pediatric population. Under ideal conditions endoscopies for children should be performed by experienced pediatric endoscopists. In this study we report our experience with pediatric endoscopy at the general adult endoscopy unit in our hospital. Our goal is to quantify the number of endoscopies performed in children, as well as their indications and findings, the type of sedation or anesthesia used, and the time waiting for the test to occur. Our experience demonstrates that endoscopists in a general adult gastroenterology department, working together with pediatricians, may perform a relevant number of endoscopies in children in a fast, safe, effective manner.La endoscopia gastrointestinal es una técnica segura y eficiente con mínimas complicaciones, así como una útil herramienta diagnóstica en la población pediátrica.

Fueron variables para estudio, edad, sexo, peso corporal en kilogramos, hemoglobina, tensiones arteriales sistólica y diastólica, frecuencia cardíaca, complicaciones posinducción y las dosis de tiopental sódico en miligramos por kilogramos. Se utilizó análisis de varianza. Fueron significativas las variaciones con p Fifty six medical histories with the anesthesiology protocols of 26 patients with chronic renal failure (CRF and of 30 sound patients were reviewed. Age, sex, body weight in kg, haemoglobine, systolic and diastolic arterial tensions, heart rate, postinduction complications, and thiopental sodium doses in mg x kg were the variables used in this study. The variance analysis was used. Variations with p < 0,05 were significant. The sample was divided into patients without CRF (group I and with CRF (group II. There were no differences between the thiopental sodium anesthetic doses of both groups (4,59 + 3,88 mg/kg, group I and 5,89 + 4,15 mg/kg, group II. Arterial tension descended more in patients from group II as a result of anesthesia induction. This variation did not mean a greater incidence of hypotension between both groups (16,6 % in I and 15,3 % in II. It is concluded that in our enviroment the necessary dose of thiopental sodium to induce anesthesia in patients with and without CRF was not statistically different. However, the fal of arterial tensions was more important in group II. It is recommended to take more precaution in the administration of thiopental sodium to these patients

    Full Text Available Se presenta la experiencia dermatológica obtenida durante el seguimiento prospectivo de 114 pacientes con trasplante renal, atendidos en el Hospital Universitario San Vicente de Paúl, de Medellín; su evolución post-trasplante fluctuaba entre 2 meses y 13 anos y el seguimiento dermatológico fue por dos anos. Se encontró un número elevado de manifestaciones cutáneas (promedio 4,8 por paciente; las más frecuentes fueron: acné, micosis, hirsutismo y xerosis; no se hallaron lesiones malignas. No hubo asociación de las manifestaciones cutáneas con la edad del paciente, el tipo de donante o el esquema Inmunosupresor. Dada la alta frecuencia de patología cutánea se sugiere que estos pacientes sean educados adecuadamente sobre este aspecto y examinados periódicamente con el fin de detectar y manejar a tiempo sus problemas dermatológicos benignos O potencialmente malignos.

Variables relativas al paciente, realización de tratamientos y resultados fueron evaluadas y correlacionadas con las variables clave: número de desbridamientos quirúrgicos y cultivos aislados de agentes infecciosos. RESULTADOS: La tasa de infección, después de la cirugía, fue 9,83%. Algunas variables fueron relacionadas con el número de desbridamientos quirúrgicos realizados y no fue posible establecer alguna relación. No obstante, se descubrió que pacientes con un mayor número de tratamientos quirúrgicos realizados tuvieron una tasa mayor de dolor postoperatorio. CONCLUSIÓN: Pacientes que recibieron un mayor número de tratamientos realizados tuvieron más dolor en el período postoperatorio. No hubo correlación, estadísticamente significativa, entre el número de desbridamientos o agentes infecciosos, o con otras variables.

    Kidney cancer represents 3 % of the tumors in adults. In the United States, the 45% is diagnosed in early stages. Its natural history is characterized for being absolutely unpredictable and probably related to hormonal, immunologic and unknown factors. There are patients in advanced stage with prolonged or low average survival and even with metastasis declination. These particularities along with the lack of prospective random studies make difficult to establish which is the roll of the adjuvant radiotherapy, being considered not standard since 1997. [Spanish] El cancer de rinion representa el 3% de los tumores en adultos. En Estados Unidos el 45% se diagnostica en estadios tempranos. Su historia natural se caracteriza por ser absolutamente impredecible, probablemente relacionado a factores hormonales, inmunologicos y desconocidos; hay pacientes con enfermedad avanzada con prolongada o corta supervivencia media e incluso con regresion de metastasis. Estas particularidades, juntamente con la falta de estudios prospectivos aleatorios dificultan establecer cual es el rol de la radioterapia adyuvante, considerandose no estandar desde 1997.

Papillary thyroid carcinoma (PTC in 96%. The 63% was SI; 14% SII; 19% SIII and 4% SIV. During follow-up, we observed that 90% of patients with Tg between 2 and 10 had evidence of residual TC, and 100% with Tg > 10 ng/ml, whereas 18% of those whose stimulated Tg < 2 presented positive image. There was not found significative correlation with pathologic antecedents or relevant image signs. In conclusion: TCP was the most frequent carcinoma in women, in patients younger than 45 years and in those who have euthyroid function. A stimulated serum thyroglobulin level was a good indicator for residual TC, but failed to select those patients who were disease free.

Image quality of each study was evaluated using subjective criteria from two expert observers, without previous information about administered activity, and objective criteria based on signal/noise ratios and variance of the random noise in the images. They were used to develop clustering and discriminant analysis over the independent variables to detect groups of images with differentiated quality from the physical and mathematical point of view. As a conclusion, we found that it is possible to reduce the given activities in 50%. (Author) 30 refs.

    Full Text Available Resumen Una de las actividades que se realizan en el proceso educativo con herramientas de ayuda a la toma de decisión (HATD es ayudarles a explorar sus valores mediante las "tarjetas de valores". El objetivo del estudio fue, conocer los valores de las personas con Enfermedad Renal Crónica en la elección de modalidad de Tratamiento Sustitutivo Renal y analizar si existía relación entre los mensajes de las tarjetas y la modalidad de tratamiento. Estudio retrospectivo. Se incluyeron 281 pacientes que pasaron por el proceso de educación con HATD entre los años 2011-2016. Los datos se obtuvieron de los registros de enfermería de la historia clínica. Se estudiaron variables demográficas, tarjetas de valores y elección de tratamiento. La muestra fue de 281 pacientes. Las 3 tarjetas que obtuvieron un mayor porcentaje de elección fueron, Personal sanitario responsable del tratamiento (14,20%, Ser independiente (13,65%, Impacto para la familia (13,30%; según la modalidad de tratamiento elegida, HD: Impacto para la familia (15,94%, Personal sanitario responsable del tratamiento (15,58%, Ser independiente (13,04%. DP: Ser independiente (18,95%, Personal sanitario responsable del tratamiento (15,26%, Impacto para la familia (14,21%. Tratamiento médico conservador: Ser independiente (25,2%, Autonomía e Impacto para la familia (12,5%. Trasplante de donante vivo: Personal sanitario responsable tratamiento (30%, Ser independiente (30%, Autonomía (10%. Podemos concluir que la mayoría de los mensajes de las tarjetas, parecen estar en concordancia con la modalidad elegida. No hay valores propios de una modalidad de tratamiento sustitutivo renal sino personas con diferentes valores que marcan la toma de decisión.

    Full Text Available INTRODUCCIÓN. La insuficiencia renal aguda se produce en horas o en algunos días, y durante su evolución se produce un deterioro del estado nutricional del paciente. El objetivo de este estudio fue caracterizar el estado nutricional de niños con esta enfermedad que requirieron terapias de reemplazo renal. MÉTODOS. Se realizó un estudio retrospectivo y transversal que incluyó a los pacientes ingresados por insuficiencia renal aguda en dos hospitales pediátricos de Santiago de Cuba entre diciembre de 2006 y diciembre de 2008. Se analizó edad, sexo, etiología, terapia de reemplazo renal, causa del uso de nutrición parenteral, evaluación nutricional según tablas cubanas de percentiles y parámetros antropométricos (edad, peso, talla y aporte de nutrientes parenterales. RESULTADOS. Eventos prerrenales fueron la causa de la insuficiencia renal aguda en el 44,4 % de los casos, y renales y posrenales, en el 33,4 y 22,2 %, respectivamente. Como método de depuración renal se utilizó la diálisis peritoneal en el 66,6 % de los casos y la hemodiálisis en los restantes pacientes. Las principales causas que motivaron la nutrición parenteral fueron las afecciones quirúrgicas, los estados hipercatabólicos, la hemorragia digestiva y la pancreatitis, en orden decreciente. Cuatro pacientes fueron evaluados como de bajo peso. CONCLUSIONES. El aporte promedio de proteínas y lípidos estuvo por debajo de los aportes nutricionales establecidos, y el aporte de kilocalorías fue superior a lo recomendado. Se deben mejorar estos parámetros en el tratamiento de estos pacientes.INTRODUCTION: Acute renal insufficiency appears in hours or in a few days and during its course there is a deterioration of patient nutritional status. The aim of present study was to characterize the nutritional status of children with this disease requiring renal replacement therapies.

    Full Text Available Objetivos: Determinar la frecuencia de secuela renal después del evento agudo de Síndrome Urémico Hemolítico (SUH en niños y los factores asociados a la presencia de secuelas. Material y métodos: Estudio descriptivo y retrospectivo. Se revisaron las historias clínicas de los pacientes con SUH en el HNCH de 1997 al 2012, y se registraron datos de características clínicas, hallazgos de laboratorio y parámetros de función renal al ingreso, al alta y a los seis meses después del alta. En los casos que no contaban con control a los 6 meses, se intentó contactar a los pacientes para tomar nuevos controles. Resultados: Siete de 12 pacientes presentaron disminución en la tasa de filtración glomerular (TFG o proteinuria o hipertensión a los 6 meses o más después del episodio agudo, con un promedio de 30,75 meses de seguimiento. Tanto en los pacientes con secuelas como con recuperación renal se encontró una distribución similar de los factores asociados a secuelas como hipertensión al alta, proteinuria al alta, necesidad de diálisis, oligoanuria, leucocitosis > 20 000 cel/mm3 y síntomas neurológicos. Sin embargo algunas variables como oligoanuria y necesidad de diálisis se encontraron a niveles por debajo de los descritos en la literatura. Conclusiones: Es claro que existen pacientes con secuelas renales luego del episodio agudo de SUH que además presentan varios factores predictores de secuelas descritos en la literatura.

Existió un predominio del sexo femenino y edad media de 44,6 años. La intubación prolongada de origen diverso fue la causa de la estenosis en 4 de los 5 pacientes y en 1 fue posterior a la reparación de lesión traqueal yatrógena. La instalación de la estenosis tuvo lugar entre 8 días y 3 meses. La tomografía lineal en 3 pacientes y en 2 la radiografía simple de tráquea anteroposterior y lateral verificaron el diagnóstico. La endoscopia traqueobronquial preoperatoria fue de utilidad en la caracterización de la estenosis. En todos los pacientes se realizó tratamiento quirúrgico al resecar el área estenótica con posterior anastomosis terminoterminal y fijación del cuello en flexión durante 8 días como promedio. Dos pacientes mostraron granulomas en el nivel de la línea de sutura, los cuales fueron tratados por vacuolización con láser. No se reportó mortalidad en la muestra estudiadaA retrospective and descriptive study was conducted by using the medical histories of 5 patients with tracheal stenosis, mostly as a result of prolongued intubation. Aspects connected with the diagnosis, treatment and complications were taken into account. It was observed a predominance of females and an average age of 44.6. Prolongued intubation of different origin was the cause of stenosis in 4 of the 5 patients, whereas in the other it occurred after the reparation of the tracheal and athrogenous lesion. The installation of stenosis took place between 8 days and 3 months. Lineal tomography in 3 patients and anteroposterior and lateral simple X-ray of the trachea in 2 confirmed the diagnosis.

    Full Text Available Con el objetivo de proponer un procedimiento integrador para el análisis retrospectivo y prospectivo de sistemas lecheros, se realizó una investigación documental basada en una revisión bibliográfica narrativa. La información provino de dos tipos de fuente: primaria y secundaria, mientras que la estrategia de búsqueda se basó en combinaciones de palabras clave. El procedimiento, que consistió en realizar 22 operaciones de manera ordenada, se basó en el enfoque de ingeniería de sistema y contempló las cuatro dimensiones generales (productiva, económica, social y ambiental que definen la sostenibilidad de los sistemas agropecuarios. Se utilizó este enfoque por considerar que el análisis de dichos sistemas se debe orientar al examen holístico de lo que en ellos ocurre, así como a proponer soluciones concretas con bases científicas. Los resultados demostraron que la secuencia de operaciones propuesta puede ser considerada como un procedimiento útil para realizar el análisis retrospectivo y prospectivo de sistemas lecheros, con un enfoque sistémico e integrador que permite interrelacionar la caracterización del sistema de producción de leche en pastoreo, el análisis de la eficiencia y el diseño de alternativas tecnológicas para la mejora de este.

    Full Text Available O viés retrospectivo é o fenômeno de perceber e avaliar eventos diferentemente, uma vez que eles tenham ocorrido. Dada uma falha cognitiva, pessoas tendem a ter distorções da memória e a produzir falsas sensações de inevitabilidade e previsibilidade. Os objetivos deste trabalho foram fazer uma revisão de literatura do viés retrospectivo e discutir as implicações teóricas e práticas do tema. Uma pesquisa, realizada nas principais bases de dados do país, não encontrou nenhum artigo relacionado com o tema. A partir de uma seleção das principais pesquisas internacionais sobre o assunto, foi feita uma análise que mostrou os níveis cognitivos do viés retrospectivo, suas implicações e as estratégias usadas para atenuar o viés. Nas considerações finais, são discutidos o impacto e a importância do conhecimento desse fenômeno no dia a dia de tomadores de decisão e cidadãos, assim como a necessidade de se explorar o tema em pesquisas nacionais.

    Full Text Available A laringomalácia é a anomalia congênita da laringe mais frequente, sendo responsável por cerca de 60% a 75% dos casos de estridor congênito. Apesar de seu curso benigno e autolimitado, 10% dos casos necessitam de intervenção. Atualmente, as supraglotoplastias são consideradas o tratamento padrão da laringomalácia grave. OBJETIVO: Descrever a experiência adquirida pelos autores no tratamento cirúrgico dos pacientes com laringomalácia grave. Metodologia: Estudo retrospectivo. MÉTODO: Os prontuários de 11 casos consecutivos de laringomalácia grave, submetidos ao tratamento cirúrgico entre 2003 e 2012, foram analisados quanto à idade, gênero, sintomas, doenças associadas, técnica cirúrgica adotada, tempo de extubação, complicações cirúrgicas, tempo de internação e evolução clínica. RESULTADOS: Dos 11 casos de laringomalácia grave, seis pacientes (54,5% foram operados com o uso do laser de CO2 e em cinco pacientes (45,5% foram realizadas a técnica a frio. Apenas um paciente (9,1% necessitou reabordagem cirúrgica. Não foram observados casos de complicações cirúrgicas. Todos os pacientes apresentaram melhora clínica importante. CONCLUSÃO: A supraglotoplastia mostrou-se um procedimento eficaz e seguro no tratamento da laringomalácia grave.

    Full Text Available La injuria renal aguda (IRA es un evento mórbido de gran impacto en la vida de las personas. La tasa de letalidad de la IRA ha sido un tema relevante y se han estudiado muchos factores relacionados. Objetivos: Determinar el perfil epidemiológico de los pacientes con IRA en un hospital de Lima y los factores asociados a la mortalidad durante el periodo de hospitalización. Material y métodos: Estudio descriptivo, retrospectivo de una cohorte de pacientes incidentes con diagnóstico de IRA. Se calculó la letalidad bruta y la ajustada a tiempo de permanencia hospitalaria. Se usó la regresión multivariante de Cox, así como el mejor modelo para regresión logística binaria asociada a letalidad. Se aceptó una significancia estadística de p<0,05. Resultados: Se identificaron 90 pacientes con IRA en los años 2002, 2003 y 2004 (incidencia de 30, 39 y 21 pacientes/año, respectivamente. Su permanencia hospitalaria fue 13,44 ± 1,66 (promedio±1ES días, la tasa bruta de letalidad 39% y la tasa ajustada 2,89 fallecidos/100 días de hospitalización. Las variables relacionadas al riesgo de muerte en el tiempo fueron el estado de shock, el diagnóstico de sepsis y la disfunción respiratoria al momento de la admisión. Conclusiones: La gravedad clínica como condición al momento de la admisión al centro hospitalario, el estado séptico y la presencia de disfunción respiratoria, fueron los factores que influenciaron en el pronóstico de supervivencia de pacientes con IRA.

    Conclusiones: El consenso en analizar el perfil lipídico en los pacientes con ERC indica el reconocimiento del alto riesgo cardiovascular de esta enfermedad. La ausencia de acuerdo en considerar la función renal o la albuminuria, tanto en la elección de la estatina como durante el seguimiento, indica un conocimiento limitado de las diferencias entre estatinas en relación con la ERC, por lo que sería deseable disponer de una guía/documento de consenso sobre uso de estatinas en la ERC.

    Full Text Available Renal cryoablation is an alternative minimally-invasive method of treatment for localized renal cell carcinoma. The main advantages of this methodology include visualization of the tumor and the forming of "ice ball" in real time, fewer complications compared with other methods of treatment of renal cell carcinoma, as well as the possibility of conducting cryotherapy in patients with concomitant pathology. Compared with other ablative technologies cryoablation has a low rate of repeat sessions and good intermediate oncological results. The studies of long-term oncological and functional results of renal cryoablation are presently under way.

Resumen: Antecedentes: En la práctica clínica habitual la prescripción de análogos de vitamina D (AVD en la enfermedad renal crónica (ERC se asocia con frecuencia a un descenso de la función renal estimada cuyo origen no es bien conocido. Objetivos: Analizar el efecto de la suspensión de un tratamiento previo con AVD en ERC avanzada, y determinar los factores asociados con los cambios de función renal. Material y métodos: Estudio de cohorte retrospectivo en pacientes adultos incidentes con ERC avanzada. El subgrupo caso estaba siendo tratado con AVD y esta medicación fue suspendida en la primera visita. El subgrupo control no había sido tratado con AVD y fueron elegidos por criterios de coincidencia para datos relevantes relacionados con la progresión de la ERC. La variable de resultado principal fue el cambio de filtrado glomerular, tanto el estimado (FG-MDRD como el medido (media del aclaramiento de creatinina y urea, con respecto al siguiente control analítico. Parámetros basales relacionados con el metabolismo mineral y la generación de creatinina fueron analizados como determinantes potenciales de los cambios de la función renal. Resultados: Se incluyeron 67 pacientes casos y otros 67 controles. El 67% de los casos mejoró la función renal, mientras que el 72% de los controles empeoró (p < 0,0001. El cambio FG-MDRD en casos y controles fue +0,455 ± 0,997 vs. −0,436 ± 1,103 ml/min/1,73 m2/mes (p < 0,0001, respectivamente. La excreción total de creatinina era ligeramente superior en los casos, pero la diferencia con respecto a los controles no fue significativa.Por regresión logística y lineal multivariante, el calcio sérico total basal fue uno de los principales determinantes tanto de la recuperación de la función renal (odds ratio = 3,49; p = 0,001, como de la magnitud de esta recuperaci

    Between 1964 to 1990, 458 patients diagnosed of bladder cancer have been treated with radical radiotherapy in our department. The 5-years and 10-years actuarial survival rates were 37% and 27% respectively. The 5-years and 10-years actuarial local control rates, evaluated in 404 patients, were 41% and 38%. In regard to survival, T stage (p=0.013), advanced intravesical extension or multicentrity (p>0.0001), and squamous differentiation (p<0.0001), reached statistical significance as adverse prognostic factors. In 248 patients, with invasive transitional carcinoma, radical radiotherapy alone was used. In this group of patients, T stage (p=0.006) and advanced intravesical extension or multicentrity (p=0.0002) were adverse prognostic factors for survival. Our results suggest that radical radiotherapy must be considered and alternative to surgery in management of bladder cancer. On the basis of prognostic factors evidenced in this series a subgroup of patients with low probability of survival when treated with exclusive radiotherapy are defined. This patients must be included in clinical research protocols. (Author) 44 refs.

    The absorbed dose of the kidneys during renal function studies of adult patients is estimated through biokinetics of radiopharmaceuticals containing the {sup 123}I/{sup 131}I (hippuran) e {sup 111}In (DPTA). Using the methodology MIRD and representation Cristy-Eckerman for adult kidneys, it is shown that dosimetric contributions of organs of biokinetics {sup 123}I/{sup 131}I (hippuran) e {sup 111}In (DPTA) are significant, in estimative of dose for renal function studies. Dosimetric contributions (body and whole bladder, kidneys excluding) are given by 11.90% (for {sup 123}I), 4.97% (for {sup 131}I) and 28.32% (for {sup 111}In). In all cases, the dosimetric contributions are mainly due to photons issued by the whole body.

    Full Text Available INTRODUCTION: Renal hemangioma is a relatively rare benign tumor, seldom diagnosed as a cause of hematuria. CASE REPORT: A female 40-year old patient presented with continuous gross hematuria, anemia and episodic right lumbar pain, with onset about 3 months previously. The patient underwent multiple blood transfusions during her hospital stay and extensive imaging propedeutics was performed. Semi-rigid ureterorenoscopy evidenced a bleeding focus in the upper calix of the right kidney, with endoscopic treatment being unfeasible. The patient underwent right upper pole nephrectomy and presented a favorable outcome. Histopathological analysis of the surgical specimen showed that it was a renal hemangioma. COMMENTS: Imaging methods usually employed for diagnostic investigation of hematuria do not have good sensitivity for renal hemangioma. However, they are important to exclude the most frequent differential diagnoses. The ureterorenoscopy is the diagnostic method of choice and endoscopic treatment can be feasible when the lesion is accessible and electrocautery or laser are available. We emphasize the open surgical treatment as a therapeutic option upon failure of less invasive methods.

    Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

    1979-01-01

    Stone in the urinary tract has fascinated the medical profession from the earliest times and has played an important part in the development of surgery. The earliest major planned operations were for the removal of vesical calculus; renal and ureteric calculi provided the first stimulus for the radiological investigation of the viscera, and the biochemical investigation of the causes of calculus formation has been the training ground for surgeons interested in metabolic disorders. It is therefore no surprise that stone has been the subject of a number of monographs by eminent urologists, but the rapid development of knowledge has made it possible for each one of these authors to produce something new. There is still a technical challenge to the surgeon in the removal of renal calculi, and on this topic we are always glad to have the advice of a master craftsman; but inevitably much of the interest centres on the elucidation of the causes of stone formation and its prevention. Professor Pyrah has had a long an...

    Full Text Available Introdução: A tuberculose (TB infantil permanece como uma das doenças mais prevalentes e preocupantes no mundo, sobretudo em nações em desenvolvimento, onde as taxas são ainda mais elevadas e os casos descritos subestimados pela dificuldade em se estabelecer um diagnóstico definitivo. Dessa forma, este estudo tem como objetivo descrever o perfil clínico e epidemiológico dos pacientes com TB infantil pulmonar e extrapulmonar. Métodos: Foram avaliados retrospectivamente, através de questionário, pacientes com idade de até 15 anos, internados no Serviço de Pediatria do HCPA, no período de janeiro de 2002 a setembro de 2007.   Resultados: Dos 52 pacientes incluídos, 63% apresentavam TB pulmonar. Das formas extra-pulmonares, a meningoencefalite foi a mais prevalente (22%. Comorbidades foram dectadas em 31 (60% pacientes, dos quais 15 (29% apresentavam desnutrição grave, 9 (18% HIV positivo e 7 (13% pneumopatia crônica. Das manifestações clínicas, febre e tosse estavam presentes na maioria dos pacientes. O padrão radiológico predominante foi o de consolidação pulmonar (51%. A maioria dos pacientes referia história de contato com paciente bacilífero (64%. Conclusão: A TB pulmonar representa a principal forma de apresentação clínica da TB, sendo o diagnóstico feito de forma presuntiva na maioria dos casos. O diagnóstico baseado na comprovação bacteriológica foi obtido numa minoria de pacientes, demonstrando a importância dos achados clínico-laboratoriais, história epidemiológica e vacinal para o diagnóstico. Nesse sentido, a criação de escores tem se tornado uma ferramenta de fácil acesso e com razoável acurácia para auxiliar o diagnóstico de TB em serviços de baixa complexidade, especialmente o ambulatorial.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    Four cases of traumatic renal artery occlusion were described and illustrated. In two cases, direct blows to the abdomen compressed the renal artery against the vertebral column. Clinically, they were severely injured with macroscopic hematuria. Aortograms showed abrupt truncation of renal arteries. In the other two, rapid deceleration caused sudden displacement of the kidney producing an intimal tear with resultant thrombosis. Although they showed little injury without macrohematuria, aortograms revealed tapered occlusion of renal arteries. One of them developed hypertension. ''Rim sign'' of post-contrast CT and hypertension resulted from traumatic renal artery occlusion were reviewed. (author)

    Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

Para ello, se lleva a cabo un estudio ex post facto, de carácter retrospectivo y con un grupo cuasi control. Se utilizan los criterios diagnósticos del DSM-IV-TR para la dependencia alcohólica, el Müncher Alkoholismus Test (MALT para valorar la gravedad del alcoholismo y el SCL-90-R como medida de la sintomatología asociada. Los resultados obtenidos muestran la presencia de numerosa sintomatología psicopatológica, con elevaciones significativas en la mayoría de las dimensiones del SCL-90-R, tanto en los hombres como en las mujeres de la muestra. La comparación con las muestras normativas refleja que los alcohólicos de la muestra presentan más síntomas psicopatológicos que la población normal, pero menos que la población psiquiátrica. Asimismo, la gravedad del alcoholismo se relaciona de forma significativa con la mayor presencia e intensidad de comorbilidad. Por último, se comentan las implicaciones de este estudio para la práctica clínica y para la investigación futura.

    Renal artery disease is a potentially correctable cause of hypertension. Previous studies have suggested the utility of duplex sonography in accurately detecting and grading the severity of renal artery stenosis. The purpose of this paper is to evaluate color flow Doppler for this use. Forty-three kidneys were examined by color-flow Doppler and conventional duplex sampling in patients with suspected renovascular hypertension or those undergoing aortography for unrelated reasons. Doppler tracings were obtained from the renal arteries and aorta with calculation of the renal aortic ratio (RAR) and resistive index (RI). Results of Doppler sampling with color flow guidance were compared with aortograms in a blinded fashion

    Full Text Available Primary renal cell carcinomas have rarely been reported in patients with crossed fused renal ectopia. We presented a patient with right to left crossed fused kidney harbouring renal tumor. The most frequent tumor encountered in crossed fused renal ectopia is renal cell carcinoma. In this case, partial nephrectomy was performed which pave way to preservation of the uninvolved both renal units. Due to unpredictable anatomy, careful preoperative planning and meticulous delineation of renal vasculature is essential for preservation of the uninvolved renal units.

    Full Text Available Estudios epidemiológicos han señalado que el Síndrome Metabólico (SM es un factor de riesgo independiente, que incidiría en el desarrollo de daño renal crónico, existiendo además una relación gradual entre el número de componentes del SM y la prevalencia de enfermedad renal crónica (ERC. El SM corresponde a una agrupación de factores de riesgo: Obesidad abdominal, hipertrigliceridemia, colesterol HDL bajo, elevación de la presión arterial, elevación de la glicemia en ayunas, que se asocian a un aumento del riesgo de desarrollo de diabetes mellitus y enfermedades cardiovasculares. Debido a limitaciones metodológicas de los estudios actuales, no ha sido posible demostrar si el SM es causa o efecto de ERC. Se describen los mecanismos fisiopatológicos del SM y de su asociación a ERC. La American Heart Association recomienda un manejo agresivo y enfocado en los múltiples factores de riesgo del SM; sin embargo, aún no existen estudios que hayan evaluado si este tipo de intervenciones en pacientes con SM puede reducir la incidencia o la progresión de ERC. Se requieren estudios prospectivos e intervencionales que permitan medir de manera exacta el impacto del tratamiento del SM y la obesidad en el riesgo de ERC.

    Background Hypothyroidism induces significant changes in the function of organ systems such as the heart, muscles and brain. Renal function is also influenced by thyroid status. Physiological effects include changes in water and electrolyte metabolism, notably hyponatremia, and reliable alterations of renal hemodynamics, including decrements in renal blood flow, renal plasma flow, glomerular filtration rate (GFR). Objective Renal function is profoundly influenced by thyroid status; the purpose of the present study was to determine the relationship between renal function and thyroid status of patients with hypothyroidism. Design and Patients In 5 patients with primary hypothyroidism and control group renal functions are measured by serum creatinine and glomerular filtration rate (GFR) using modified in diet renal disease (MDRD) formula. Result In hypothyroidism, mean serum creatinine increased and mean estimated GFR decreased, compared to the control group mean serum creatinine decreased and mean estimated GFR Increased. The hypothyroid patients showed elevated serum creatinine levels (> 1.1mg/dl) compared to control group (p value .000). In patients mean estimated GFR decreased, compared to mean estimated GFR increased in the control group (p value= .002).

    Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, vascular reconstructions and various surgical and radio logic techniques being performed in recent years. We report the presence of bilateral triple renal arteries, discovered on routine dissection of a male cadaver. On the right side, one additional renal artery originated from the abdominal aorta (distributed to superior pole of the kidney) and one other originated from the right common iliac artery (distributed to lower pole of the kidney). On the left side, both additional renal arteries originated from the abdominal aorta. Our observation has been compared with variations described in the literature and their clinical importance has been emphasized. (author)

  13. Renal imaging in paediatrics

    International Nuclear Information System (INIS)

    Porn, U.; Hahn, K.; Fischer, S.

    2003-01-01

    The most frequent renal diseases in paediatrics include urinary tract infections, hydronephrosis, kidney anomalies and reflux. The main reason for performing DMSA scintigraphy in paediatrics is the detection of cortical abnormalities related to urinary tract infection. Because the amount of tracer retained in the tubular cells is associated with the distribution of functioning renal parenchyma in the kidney, it is possible, to evaluate the split renal function. In comparison to ultrasound and intravenous urography the sensitivity in the detection of acute as well as chronic inflammatory changes is very high, however less specific. An indication for a renography in neonates and children is beside an estimation of the total renal function and the calculation of the split renal function, the assessment of renal drainage in patients with unclear dilatation of the collecting system in ultrasound. The analysis of the time activity curve provides, especially for follow-up studies, a reproducible method to assess the urinary outflow. The diuretic scintigraphy allows the detection of urinary obstruction. Subsequently it is possible to image the micturition phase to detect vesico-ureteric reflux (indirect MCU) after drainage of tracer from the renal pelvis. An reflux in the ureters or the pelvicalyceal system is visible on the scintigraphic images and can be confirmed by time activity curves. A more invasive technique is the direct isotope cystography with bladder catheterization. The present paper should give an overview about the role of nuclear medicine in paediatric urology. (orig.)

  14. Perioperative acute renal failure.

    LENUS (Irish Health Repository)

    Mahon, Padraig

    2012-02-03

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

  20. Cadmium and renal cancer

    International Nuclear Information System (INIS)

    Il'yasova, Dora; Schwartz, Gary G.

    2005-01-01

    Background: Rates of renal cancer have increased steadily during the past two decades, and these increases are not explicable solely by advances in imaging modalities. Cadmium, a widespread environmental pollutant, is a carcinogen that accumulates in the kidney cortex and is a cause of end-stage renal disease. Several observations suggest that cadmium may be a cause of renal cancer. Methods: We performed a systematic review of the literature on cadmium and renal cancer using MEDLINE for the years 1966-2003. We reviewed seven epidemiological and eleven clinical studies. Results: Despite different methodologies, three large epidemiologic studies indicate that occupational exposure to cadmium is associated with increased risk renal cancer, with odds ratios varying from 1.2 to 5.0. Six of seven studies that compared the cadmium content of kidneys from patients with kidney cancer to that of patients without kidney cancer found lower concentrations of cadmium in renal cancer tissues. Conclusions: Exposure to cadmium appears to be associated with renal cancer, although this conclusion is tempered by the inability of studies to assess cumulative cadmium exposure from all sources including smoking and diet. The paradoxical findings of lower cadmium content in kidney tissues from patients with renal cancer may be caused by dilution of cadmium in rapidly dividing cells. This and other methodological problems limit the interpretation of studies of cadmium in clinical samples. Whether cadmium is a cause of renal cancer may be answered more definitively by future studies that employ biomarkers of cadmium exposure, such as cadmium levels in blood and urine

    Atherosclerotic renal artery stenosis (RAS) is the single largest cause of secondary hypertension; it is associated with progressive renal insufficiency and causes cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy, including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid-lowering agents, and antiplatelet therapy, is advised in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe RAS are likely to benefit from renal artery revascularization. Screening for RAS can be done with Doppler ultrasonography, CT angiography, and magnetic resonance angiography. Copyright © 2015 Elsevier Inc. All rights reserved.

    Acute renal failure (ARF) may be due to obstructive uropathy or renal parenchymal disease. Twenty-five children with acute renal failure secondary to renal parenchymal disease underwent ultrasonographic examination of the kidneys. Changes of renal size and cortical echogenicity were correlated with renal function. All patients presented with bilaterally enlarged kidneys with the exception in renal function resulted in normalization of renal size. With regard to cortical echogenicity two groups were formed. Group A comprised 11 patients whose kidneys had the same echogenicity as the liver, while in group B the kidneys were more echogenic (14 patients). Cortical echogenicity was always increased. Determination of creatinine levels showed a statistically significant difference between group A (3.32 mg% ± 1.40 S.D.) and group B (5.95 mg% ± 1.96 S.D.), p < 0.001. Changes in renal function were paralleled by rapid changes in renal size and cortical echogenicity. (orig.)

    The frequent application of ultrasound and radiological imaging for non-urological indications in recent years has resulted in an increase in the diagnosis of small renal masses. The treatment options for patients with a small renal mass include active surveillance, surgery (both open and minimally invasive) as well as ablative techniques. As there is a risk for metastatic spread even in small renal masses surgical extirpation remains the treatment of choice in most patients. Ablative procedures, such as cryoablation and radiofrequency ablation are appropriate for old and multi-morbid patients who require active treatment of a small renal mass. Active surveillance is an alternative for high-risk patients. Meticulous patient selection by the urologist and patient preference will determine the choice of treatment option in the future.

    Patterson, J.E.; Andriole, V.T.

    1987-01-01

    Our knowledge of the spectrum of renal abscesses has increased as a result of more sensitive radiologic techniques. The classification of intrarenal abscess now includes acute focal bacterial nephritis and acute multifocal bacterial nephritis, as well as the previously recognized renal cortical abscess, renal corticomedullary abscess, and xanthogranulomatous pyelonephritis. In general, the clinical presentation of these entities does not differentiate them; various radiographic studies can distinguish them, however. The intrarenal abscess is usually treated successfully with antibiotic therapy alone. Antistaphylococcal therapy is indicated for the renal cortical abscess, whereas therapy directed against the common gram-negative uropathogens is indicated for most of the other entities. The perinephric abscess is often an elusive diagnosis, has a more serious prognosis, and is more difficult to treat. Drainage of the abscess and sometimes partial or complete nephrectomy are required for resolution. 73 references

    INTRODUCTION: Lithium is established as an effective treatment of mania, of depression in bipolar and unipolar disorder, and in maintenance treatment of these disorders. However, due to the necessity of monitoring and concerns about irreversible adverse effects, in particular renal impairment......, after long-term use, lithium might be underutilized. METHODS: This study reviewed 6 large observational studies addressing the risk of impaired renal function associated with lithium treatment and methodological issues impacting interpretation of results. RESULTS: An increased risk of renal impairment...... associated with lithium treatment is suggested. This increased risk may, at least partly, be a result of surveillance bias. Additionally, the earliest studies pointed toward an increased risk of end-stage renal disease associated with lithium treatment, whereas the later and methodologically most sound...

    Full Text Available Abstract The renal artery pseudoaneurysm embody a rare vascular complication coming of percutaneous procedures, renal biopsy, nephrectomy, penetrating traumas and more rarely blunt traumas. The clinical can be vary according the patient, the haematuria is the symptom more commom. Is necessary a high level of clinical suspicion for your diagnosis, this can be elucidated by through complementary exams as the eco-color Doppler and the computed tomography scan (CT. This report is a case of a patient submitted a right percutaneous renal biopsy and that, after the procedure started with macroscopic haematuria, urinary tenesmus and hypogastric pain. The diagnosis of pseudoaneurysm was given after one week of evolution when the patient was hospitalized because gross haematuria, tachycardia, hypotension and hypochondrium pain. In the angiotomography revealed a focal dilation of the accessory right renal inferior polar artery, dilation of renal pelvis and all the ureteral course with presence hyperdenso material (clots inside the middle third of the ureter. The treatment for the majority of this cases are conservative, through arterial embolization, indicated for thouse of smaller dimensions in patients who are hemodynamically stable. However, it was decided by clinical treatment with aminocaproic acid 1 g, according to previous studies for therapy of haematuria. The patient received discharge without evidence of macroscopic haematuria and with normal renal ultrasound, following ambulatory care.

    Full text: Renal artery stenosis (RAS) is a common condition that may lead to hypertension, progressive renal dysfunction and cardiovascular morbidity. Catheter-based therapy for symptomatic, haemodynamically significant, RAS has become the preferred method of revascularization. Balloon angioplasty has been the traditional treatment of choice for fibromuscular dysplasia, however stents are increasingly used for the treatment of atheromatous lesions; in many cases-such as in ostial lesions-, direct stenting is strongly indicated. Despite the increased use of endovascular therapy for renal artery stenosis, there is still controversy regarding the optimal management and the net benefit of this treatment. Several randomized trials of balloon angioplasty or stenting for renal artery stenosis compared with medical therapy alone have been conducted, however these could not show definite advantage of endovascular therapy. Problems encountered with those trials include enrollment of small number of patients, frequent crossover from medical to interventional therapy compromising the intention-to-treat results, or selection of patients that are not expected to show clear benefit. The Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) is the most important of these trials; however, it,s study design was faulty and therefore did not provide conclusive evidence to answer the question of whether angioplasty and stenting or medical therapy is the best treatment for haemodynamically significant RAS. All expectations are now focused on the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) trial which was designed to answer the same question, and its methodologies took into consideration the weaknesses of the ASTRAL trial. Regarding stent device itself, it seems that the optimal design is probably a stainless steel, laser cut, open-cells stent mounted on a rapid exchange delivery balloon catheter compatible with 0.014-in and 0.018-in guidewire.

    Renal colic in pregnant women is a serious condition, mainly when is associated with fever. Our retro-prospective study analyzes 111 cases managed conservatively or with endourological procedures for renal colic--insertion of JJ stents and percutaneous nephrostomy. Clinical evolution determined the insertion of JJ stents in 60 cases and the failure of this procedure imposed percutaneous nephrostomy in 5 cases. In 56 cases urinary tract infection was associated and in 2 cases, despite all efforts, the patients deceased due to sever sepsis. The immediate drainage of the upper urinary tract for renal colic in pregnancy is the recommended treatment, especially when the pain is associated with fever. JJ stens were well tolerated, even when they were replaced after 3 months. Pregnant women with a history of UTI or stone disease should be carefully followed-up.

    A total of 174 patients underwent simple nephrectomy in case of clinically operable kidney cancer without demonstrable metastases. Of these 85 received preoperative irradiation to the kidney and the regional lymph nodes (3000-4000 rad in 3-4 weeks). Prognosis was not influenced by preoperative irradiation. The preoperatively assessable prognostic criteria were sex and sedimentation rate: ESR >= 30 and being male worsened prognosis. The clinical T-categories of the UICC were not related to prognosis. Of the microscopic examination of the nephrectomy specimen, renal vein invasion and to a lesser extent a low degree of differentiation appeared to worsen prognosis. The prognostic influence of the P-categories was caused by a higher incidence of renal vein involvement in case of higher P-category. The most important prognostic factors - ESR, renal vein involvement, and sex - were not interrelated. Elective chemotherapy, radiation therapy, and hormone therapy could be considered in certain high-risk groups. (orig.)

    Scintigraphy is useful for monitoring perfusion and function of renal transplant, as well as for diagnosing miscellaneous surgical. This non-invasive imaging technique, which uses no deleterious products, is an attractive alternative for patients. This is especially true for those patients in early post-transplant course, with immunity depression and often impairment of renal function. Otherwise, multiple indices with a large range of inter-patient values has not favoured a methodological and interpretative consensus. Furthermore, the poor specificity of renogram patterns does not allow for discrimination of all etiologies with only one scintigraphy. Nevertheless, follow-up with iterative scintigraphy may be helpful due to the high intra-patient reproducibility and to the early appreciate change of parameters, according to clinical and histological renal post-transplant outcome.

    Full Text Available Leiomyosarcomas are rare malignant tumors of the kidney. They may arise from the renal capsule, renal vein, renal pelvic musculature or renal parenchyma. Renal pelvis is an uncommon site of occurrence, with around 10 cases reported in the literature so far. Here we present a 60-year-old male who presented with increased urinary frequency, lower limb weakness, anorexia and weight loss. Imaging showed a right renal mass. A renal cell carcinoma was suspected clinically. A right nephrectomy was performed, which showed a large circumscribed mass in the hilar region. Histology revealed a tumor mass arising from the renal pelvis. The tumor was composed of spindle cells arranged in fascicles. Immunohistochemistry showed tumor cells to be positive for smooth muscle actin (SMA and desmin (Des and negative for cytokeratin (CK, HMB 45, CD117 (C-kit, and CD34. That confirmed the diagnosis of leiomyosarcoma.

    Essential hypertension remains one of the biggest challenges in medicine with an enormous impact on both individual and society levels. With the exception of relatively rare monogenetic forms of hypertension, there is now general agreement that the condition is multifactorial in nature and hence requires therapeutic approaches targeting several aspects of the underlying pathophysiology. Accordingly, all major guidelines promote a combination of lifestyle interventions and combination pharmacotherapy to reach target blood pressure (BP) levels in order to reduce overall cardiovascular risk in affected patients. Although this approach works for many, it fails in a considerable number of patients for various reasons including drug-intolerance, noncompliance, physician inertia, and others, leaving them at unacceptably high cardiovascular risk. The quest for additional therapeutic approaches to safely and effectively manage hypertension continues and expands to the reappraisal of older concepts such as renal denervation. Based on the robust preclinical and clinical data surrounding the role of renal sympathetic nerves in various aspects of BP control very recent efforts have led to the development of a novel catheter-based approach using radiofrequency (RF) energy to selectively target and disrupt the renal nerves. The available evidence from the limited number of uncontrolled hypertensive patients in whom renal denervation has been performed are auspicious and indicate that the procedure has a favorable safety profile and is associated with a substantial and presumably sustained BP reduction. Although promising, a myriad of questions are far from being conclusively answered and require our concerted research efforts to explore the full potential and possible risks of this approach. Here we briefly review the science surrounding renal denervation, summarize the current data on safety and efficacy of renal nerve ablation, and discuss some of the open questions that need

    Background: Renal leiomyomas are rare benign tumors of the kidney which can be found at autopsy as small capsular nodules in about 5% of cases. The clinical incidence of such lesions is much smaller, and only case reports or small series have been reported in the imaging literature. Purpose: To describe the imaging characteristics observed in a series of eight patients with pathology-proven asymptomatic leiomyomas of the kidney. Material and Methods: We reviewed the imaging findings observed in eight patients with pathologically proven asymptomatic renal leiomyomas discovered during studies performed for reasons unrelated to the kidney. All patients had undergone computed tomography (CT), two ultrasonography, and one magnetic resonance imaging (MRI). Results: Lesions ranged in size from 1.2 to 13 cm. Six were at the periphery of the kidney, compressed its outer surface, but did not cause disruption of the cortex; two involved the renal cortex. All had regular outer margins. A cleavage plane between the tumor and the kidney was revealed at CT and/or ultrasonography in three of the cases located at the periphery. At ultrasonography, leiomyomas appeared hypoechogenic. At CT, they were slightly hyperdense before contrast medium injection; all were hypodense to the renal cortex after contrast medium. Four were homogeneous, two were slightly heterogeneous, and the remaining two were frankly heterogeneous. The lesion studied by MRI, which was homogeneous at the postcontrast CT study, had a heterogeneous structure on both T1- and T2-weighted images, with internal areas of hypointensity on T1. Conclusion: There are some imaging findings that can help to suggest the diagnosis of renal leiomyomas. First, their density: all tumors examined before contrast were hyperdense to the kidney, with density similar to that of muscles, and all had lower enhancement than the adjacent renal parenchyma. Second, the location and margins of the tumors: most were peripheral, without

A opção pelo enxerto dermoadiposo foi feita com a finalidade de repor volume na cavidade e, ao mesmo tempo, conseguir maior superfície anterior da cavidade, já que a maioria possuía cavidades contraídas. A maioria dos pacientes (53,6% não apresentou complicações, tendo sido a necrose do enxerto a complicação mais observada (32,1%. O resultado final da cirurgia foi considerado bom em 71,4% dos pacientes e ruim em 7,1%. CONCLUSÃO: O enxerto dermoadiposo é uma técnica cirúrgica simples e de bons resultados para reposição de volume em cavidades anoftálmicas. Os autores estimulam o ensino da mesma nos serviços de treinamento de jovens cirurgiões.

Sin embargo, aún existen muchos aspectos en los cuales se debe profundizar. El primero de ellos es dar solución a la diversidad terminológica existente. Al no tener un consenso sobre el concepto, se utilizan de manera indiscriminada términos como longevidad, sostenibilidad, éxito, supervivencia, duración, etc., los cuales en lugar de aclarar, generan confusión. Por otro lado, tampoco hay evidencia suficiente para sugerir alternativas que permitan a las empresas lograr ser perdurables.

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (HRS) is a unique form of renal failure associated with advanced liver dise...

    The purpose of this study is to determine characteristic CT findings in renal abscess. Twenty cases of renal abscess were retrospectively analyzed for CT findings relating to the shape and extent of the abscess, change of nephrogram, peripheral rim enhancement, wedge-shaped enhancement on delayed scans, enlargement of the kidney involved and associated findings. Seven patients had a renal abscess at the right kidney, nine at the lift kidney and two bilaterally. The abscesses were round in 18 cases and finger-like in two. Rim enhancement around renal abscess was seen in four cases (20%). Changes in the nephrogram around the abscess were seen in 12 cases (60%). In all six patients who had undergone delayed postcontrast scans, wedge-shaped enhancement was shown around the abscess (100%). In the observation of the extent of renal abscesses, 14 cases were within the kidney, six cases extended the beyond renal capsule, and two were loculated in the renal fascia itself. Renal enlargement was seen in nine cases (45%). These results suggest that CT findings such as delayed wedge-shaped enhancement, change of nephrogram, peripheral rim enhancement, renal enlargement, and associated findings are valuable for diagnosis, and that CT also gives information concerning the extent, evolution and complication of a renal abscess

    Full Text Available La preocupación por la «cantidad» ha privado durante mucho tiempo en el ámbito educativo; ha sido considerado esencial por los gobiernos la consecución de una «educación para todos». Sin embargo, el aumento de los costos no ha conllevado una mejora sustancial, una disminución efectiva de la ineficacia de los sistemas tradicionales de enseñanza; de ello dan fe las tasas de abandonos y repeticiones de curso. Esto conduce a considerar que la falta de correspondencia entre el aumento de los recursos destinados a educación y el rendimiento de las instituciones educativas sea un problema de «calidad» más que de «cantidad». De ahí que se hable hoy insistentemente de la mejora de la calidad de la educación. Al tema de la «calidad de la educación» se dedicó en 1981 un seminario organizado por la Escuela Asturiana de estudios Hispánicos. En él, Víctor García Hoz definía la calidad educativa «como el modo de ser de la educación que reúne las características de integridad, coherencia y eficacia»1, entendiendo la eficacia como la denotación de que el fin perseguido ha sido alcanzado, más que como producción de algo material, con lo que es posible hablar en términos de eficacia refiriéndose tanto a lo cuantitativo como a lo cualitativo.

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    Full Text Available Phosphorus is a common anion. It plays an important role in energy generation. Renal phosphate handling is regulated by three organs parathyroid, kidney and bone through feedback loops. These counter regulatory loops also regulate intestinal absorption and thus maintain serum phosphorus concentration in physiologic range. The parathyroid hormone, vitamin D, Fibrogenic growth factor 23 (FGF23 and klotho coreceptor are the key regulators of phosphorus balance in body.

    To evaluate the usefulness and complications of renal biopsy under ultrasonography-guidance in renal dysfunction after renal transplantation. Ultrasonography-guided renal biopsy was done in 47 patients with the transplanted kidney. The subjects consisted of 30 males and 17 females, age ranged from 16 to 66 years (average age=38 years). Biopsies were done once in 27 patients, twice in 17 patients, three times in 3 patients, a total of 70 biopsies. The success rate of renal biopsy for the accurate pathologic diagnosis and the incidence and types of complications following biopsy were evaluated. The success rate of renal biopsy for the accurate pathologic diagnosis was 96%(67/70). Pathologic diagnosis included 27 cases of acute rejection (39%), 8 cases of acute tubular necrosis (11%), 4 cases of acute rejection and acute tubular necrosis (6%), 4 cases of cyclosporin toxicity (6%), 4 cases of primary disease recurrence (6%), 4 cases of infection (6%) and others. Complications after renal biopsy included 15 cases of microscopic hematuria (21%), 1 case of gross hematuria with spontaneous cessation and 1 case of life threatening hemorrhage. Ultrasonography-guided renal biopsy is a safe and effective diagnostic method for the evaluation of renal dysfunction following renal transplantation.

    Renal angiomyoadenomatous tumour is a rare, recently described neoplasm with a distinctive histological appearance. Although reported in the pathology literature, to our knowledge, no prior reports have described its imaging appearance. We describe the computed tomography and magnetic resonance imaging features of an incidentally detected renal angiomyoadenomatous tumour that appeared as a well-marginated, solid T2-hypointense enhancing mass, in a 50-year-old woman.

    Renal oncocytoma, although rare, is being diagnosed more frequently, and criteria to differentiate it from other tumors have been described. Multiple oncocytomas have been reported, but an association between multiple oncocytomas and renal carcinoma in the same kidney has not been described. The authors report a case with two oncocytomas and a renal carcinoma in the right kidney as well as a right adrenal adenoma

    Purpose: To demonstrate the different patterns of renal infarction to avoid pitfalls. To present 'flip-flop enhancement' pattern in renal infarction. Materials and methods: Retrospective review of a total of 41 renal infarction in 37 patients were done. These patients underwent initial CT and the diagnosis of renal infarction was confirmed with either follow up CT or at surgery. Results: Twenty-three patients had wedge-shaped focal infarcts, nine patients had global and five patients had multifocal infarcts of the kidneys. Cortical rim sign was seen predominantly with global infarcts. In five patients, a 'flip-flop enhancement' pattern was observed. In two patients, planned renal biopsies due to tumefactive renal lesions were cancelled because of 'flip-flop enhancement' pattern on follow up CTs. Conclusion: Although most of our cases were straightforward for the diagnosis of renal infarction, cases with tumefactive lesions and global infarctions without the well-known cortical rim sign were particularly challenging. We describe a new sign, flip-flop enhancement pattern, which we believe solidified the diagnosis of renal infarction in five of our cases. The authors recommend further investigations for association of flip-flop enhancement and renal infarction

    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

    Full Text Available Myxomas are rare tumors that can appear in many anatomical locations. There are only 14 cases of renal involvement documented in the literature. This article reports a case of renal myxoma in an elderly woman with recurrent cystitis. After five years of follow-up, the computed tomography (CT revealed a large solid tumor mass in the left kidney. Tumor resection was performed preserving the affected kidney with histopathological diagnosis of renal myxoma. The objective of this study is to report a rare case of renal myxoma, emphasizing the importance of the differential diagnosis from other benign and malignant mesenchymal tumors.

    Full Text Available La enfermedad renal crónica constituye una patología de prevalencia e impacto creciente en la población mundial por sus múltiples complicaciones, incluyendo un riesgo cardiovascular aumentado, que representa la principal causa de morbimortalidad en pacientes nefrópatas crónicos. Sin embargo, la relevancia de las dislipidemias, especialmente, la hipercolesterolemia LDL, en el deterioro de la función renal y desarrollo de ateroesclerosis en sujetos con daño renal crónico no ha sido claramente establecida. Esta situación ha generado controversia sobre el beneficio real del uso de hipolipemiantes en estos pacientes. En base a la evidencia disponible, incluyendo estudios clínicos recientes, la recomendación más apropiada sugiere que el uso de terapia hipolipemiante basada en estatinas (con o sin ezetimiba es beneficioso desde un punto de vista cardiovascular en nefrópatas crónicos con insuficiencia renal leve a moderada antes de la diálisis. Por otro lado, no existe evidencia definitiva para apoyar el uso rutinario de este tipo de hipolipemiantes en el manejo del deterioro de la filtración glomerular y/o la proteinuria. Basándose en la evidencia analizada en esta revisión, las futuras guías clínicas para el manejo del daño renal crónico deberán incorporar el uso de estatinas y/o ezetimiba como un elemento más dentro del armamento terapéutico de este tipo de pacientes.

    The changing trend in renal surgery, transplantation and minimal invasive urology implies preprocedure evaluation of renal veins. Development of imaging methods offers new possibilities for venographic visualization. The goal of this study is to present authors experience in visualization of renal veins using 64 MDCT and to evaluate the utility in assessments of their variants. 128 patients (68 females and 60 males, mean age 53,3) with urological complaints underwent 64MDCT examination including CT angiography. Contrast enhancement includes 3-4ml/sec injection flow of 90 ml contrast medium followed by 20 ml saline at the same rate. In 23 out of 128 examined patients some of the common variants of the renal vein is found. 64 MDCT angiography visualize very well renal veins and becomes method of choice in preoperative assessment of renal vein anatomy.

    With the greater frequency of renal transplant surgery, more female pts are becoming pregnant and carrying to term. In the renal allograft blood vessels and ureter may be compressed resulting in impaired renal function and/or, hypertension. Toxemia of pregnancy is seen more frequently than normal. Radionuclide renal scan monitoring may be of significant value in this high risk obstetrical pt. After being maintained during the pregnancy, renal function may also deteriorate in the post partum period. 5 pregnant renal transplant pts who delivered live babies had renal studies with Tc-99m DTPA to assess allograft perfusion and function. No transplanted kidney was lost during or after pregnancy as a result of pregnancy. No congenital anomalies were associated with transplant management. 7 studies were performed on these 5 pts. The 7 scans all showed the uterus/placenta. The bladder was always distorted. The transplanted kidney was rotated to a more vertical position in 3 pts. The radiation dose to the fetus is calculated at 0.024 rad/mCi administered. This study demonstrates the anatomic and physiologic alterations expected in the transplanted kidney during pregnancy when evaluated by renal scan and that the radiation burden may be acceptable in management of these pts

    Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation [13]. AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

    Full Text Available El citrato es un potente inhibidor de la cristalización de sales de calcio. La hipocitraturia es una alteración bioquímica frecuente en la formación de cálculos de calcio en adultos y especialmente en niños. El pH ácido (sistémico, tubular e intracelular es el principal determinante de la excreción de citrato en la orina. Si bien la mayoría de los pacientes con litiasis renal presentan hipocitraturia idiopática, hay un número de causas para esta anormalidad que incluyen acidosis tubular renal distal, hipokalemia, dietas ricas en proteínas de origen animal y/o dietas bajas en álcalis y ciertas drogas, como la acetazolamida, topiramato, IECA y tiazidas. Las modificaciones dietéticas que benefician a estos pacientes incluyen: alta ingesta de líquidos y frutas, especialmente cítricos, restricción de sodio y proteínas, con consumo normal de calcio. El tratamiento con citrato de potasio es efectivo en pacientes con hipocitraturia primaria o secundaria y en aquellos desordenes en la acidificación, que provocan un pH urinario persistentemente ácido. Los efectos adversos son bajos y están referidos al tracto gastrointestinal. Si bien hay diferentes preparaciones de citrato (citrato de potasio, citrato de sodio, citrato de potasio-magnesio en nuestro país solo está disponible el citrato de potasio en polvo que es muy útil para corregir la hipocitraturia y el pH urinario bajo, y reducir marcadamente la recurrencia de la litiasis renal.

    Renal scintigraphy data may be analyzed automatically by the use of a processing system coupled to an Anger camera (TRIDAC-MULTI 8 or CINE 200). The computing sequence is as follows: normalization of the images; background noise subtraction on both images; evaluation of mercury 197 uptake by the liver and spleen; calculation of the activity fractions on each kidney with respect to the injected dose, taking into account the kidney depth and the results referred to normal values; edition of the results. Automation minimizes the scattering parameters and by its simplification is a great asset in routine work [fr

    Metastases are the most frequent malignant tumors of the kidney, but these lesions are of late onset in neoplastic disease. The 19 cases reported here were all investigated with various imaging techniques (CT 12 cases, ultrasonography 12 cases, urography 8 cases, angiography 2 cases, MRI 1 case). The most common primary malignancies were lung cancer, melanoma and cancer of the controlateral kidney. In this series, 8 of the lesions were solitary, and 9 were unilateral. Tumor vascularity was evaluated in 15 cases: 14 of these lesions were hypovascular. The differential diagnosis includes small cysts, lymphoma, bilateral renal cancer, multiple small abscesses and multiple small infarcts [fr

    There are conflicting reports about the renal involvement in Behcet's disease (BD). In this study we aimed to study the frequency and type of renal involvement in a group of patients with BD in Azerbaijan province that is one of the prevalent areas of BD in Iran. All cases of BD were prospectively followed between June 2004 and January 2007, and evaluated for renal dys-function (serum creatinine > 1.7 mg/dL), glomerular hematuria and proteinuria. Those patients with proteinuria > 500 mg/day and serum creatinine level > 2 mg/dL, underwent renal biopsy. From a total number of 100 patients, six patients (6%) had obvious renal involvements. Four patients had glomerular hematuria and proteinuria. Renal biopsy in two of them revealed measangial proliferative glumerulonephritis with IgA deposit in one of them and membranoproliferative glumerolonephritis in another one. Two remaining patients had serum creatinine > 2 mg/dL without any hematuria or proteinuria. Serologic study for viral agents and collagen vascular disease were negative in all patients with renal involvements. In conclusion, renal involvement in BD is not infrequent, although in most cases it is mild in nature and may be missed. (author)

    Many chronic renal diseases lead to the final common state of decrease in renal size, parenchymal atrophy, sclerosis and fibrosis. The ultrasound image show a smaller kidney, thinning of the parenchyma and its hyperechogenicity (reflecting sclerosis and fibrosis). The frequency of renal cysts increases with the progression of the disease. Ultrasound generally does not allow for the exact diagnosis of an underlying chronic disease (renal biopsy is usually required), but it can help to determine an irreversible disease, assess prognosis and avoid unnecessary diagnostic or therapeutic procedures. The main exception in which the ultrasound image does not show a smaller kidney with parenchymal atrophy is diabetic nephropathy, the leading cause of chronic and end-stage renal failure in developed countries in recent years. In this case, both renal size and parenchymal thickness are preserved until end-stage renal failure. Doppler study of intrarenal vessels can provide additional information about microvascular and parenchymal lesions, which is helpful in deciding for or against therapeutic intervention and timely planning for optimal renal replacement therapy option

    Full Text Available A patient with miliary tuberculosis and a chronic urogenital focus is described, who had a borderline renal function at diagnosis and developed overt renal failure upon daily treatment with rifampin (RMP, isoniazid (INH and ethambutol (EMB. This is the first Brazilian report of BMP induced renal damage. A renal biopsy taken on the third day of oliguria showed recent tubular necrosis with acute interstitial inflammation and granuloma formation. The aspect of the granulomatous lesion hightly suggested drug etiology because of the lack of palisading, high incidence of neutrophils and absence of facid-fast bacilli. This is the first presentation of an acute granulomatous interstitial nephritis probably due to RMP. Furthermore the pathogenesis of the renal damage caused by tuberculosis and RMP are discussed.

    Results from large epidemiological studies suggest a clear relation between low birth weight and adverse renal outcome evident as early as during childhood. Such adverse outcomes may include glomerular disease, hypertension, and renal failure and contribute to a phenomenon called fetal programming. Other factors potentially leading to an adverse renal outcome following fetal programming are maternal diabetes mellitus, smoking, salt overload, and use of glucocorticoids during pregnancy. However, clinical data on the latter are scarce. Here, we discuss potential underlying mechanisms of fetal programming, including reduced nephron number via diminished nephrogenesis and other renal (e.g., via the intrarenal renin-angiotensin-aldosterone system) and non-renal (e.g., changes in endothelial function) alterations. It appears likely that the outcomes of fetal programming may be influenced or modified postnatally, for example, by the amount of nutrients given at critical times.

    Full Text Available Primary hyperparathyroidism (PHPT is associated with nephrolithiasis and nephrocalcinosis. Hypercalciuria is one of the multiple factors that is implicated in the complex pathophysiology of stone formation. The presence of a renal stone (symptomatic or asymptomatic categorizes PHPT as symptomatic and is an indication for parathyroid adenomectomy. Progression of nephrocalcinosis is largely reversible after successful surgery, but the residual risk persists. PHPT is also associated with declining renal function. In case of asymptomatic mild PHPT, annual renal functional assessment is advised. Guidelines suggest that an estimated glomerular filtration rate (eGFR < 60 ml / minute / 1.73 m 2 is an indication for parathyroid adenomectomy. This article discusses how to monitor and manage renal stones and other related renal parameters in case of PHPT.

    Magnification selective renal arteriograms were performed on 24 patients, 12 of whom were hypertensive, and compared with non-magnification arteriograms by two observers independently. The magnification angiograms were performed on a Siemens Microfocus Bi 125/3/50 RG tube with a 0.1 mm focal spot. Of the 24 patients examined, information crucial to the diagnosis was found only on the magnification films in three patients (12.5%). Extra information compared with the non-magnification films was found in the magnification films in 12 patients (50%). No additional information was discovered in the remaining nine patients (37.5%). The magnification angiograms enabled the interlobular vessels to be visualised - this was not possible on the non-magnification films. Against the additional information gained must be weighed the disadvantages of magnification arteriography which include increased radiation dose and lengthening of procedure time plus additional injections of contrast. In conclusion, there is a place for magnification renal arteriography and the advantages seem to outweigh the disadvantages. (author)

    2018-01-01

    Peri-operative acute kidney injury is common, accounting for 30-40% of all in-hospital cases of acute kidney injury. It is associated with clinically significant morbidity and mortality even with what was hitherto regarded as relatively trivial increases in serum creatinine, and carries over a 12-fold relative risk of death following major abdominal surgery. Comorbid conditions such as diabetes, hypertension, liver disease and particularly pre-existing chronic kidney disease, as well as the type and urgency of surgery, are major risk factors for the development of postoperative acute kidney injury. As yet, there are no specific treatment options for the injured kidney, although there are several modifiable risk factors of which the anaesthetist should be aware. As well as the avoidance of potential nephrotoxins and appropriate volume balance, optimal anaesthetic management should aim to reduce the risk of postoperative renal complications. This may include careful ventilatory management and blood pressure control, as well as appropriate analgesic strategies. The choice of anaesthetic agent may also influence renal outcomes. Rather than concentrate on the classical management of acute kidney injury, this review focuses on the potential development of acute kidney injury peri-operatively, and the means by which this may be ameliorated. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

    Angiographies on forty cases of renal tuberculosis performed at the National Medical Center during a period 1960 through 1970 were reviewed. Abdominal angiography was performed via the femoral route. Some were followed by selective nephroangiography. All patients were subjected to urographyior to angiography. The results of X-ray findings in the forty cases with renal tuberculosis were follows. 1. The age varied 18 to 57 years, average 30.5 years. Twenty one patients were male, and nineteen were female. 2. The right kidney was involved in 17 cases and the left in 15 cases. Both kidneys were involved in 8 cases. 3. Urographic examination revealed pathologic changes in all patients. 4. Focal destruction in the collecting system was the most common finding in the urography of 16 patients. 5. A varying degree of hydronephrosis was present in 15 patients, of whom nine had complained of palpable mass due to hydronephrosis. 6. In the 7 patients with extensive destruction there was no observable excretion contrast medium from the diseased kidney. 7. Angiographic examination was normal in 6 of the 40 patients. 8. Decreased vascularity in the subsegmental or smaller arteries of the affected kidney was the most frequent finding, being found in 34 patients. 9. Occlusion or abrupt termination of the subsegmental arteries was present in 4 patients. 10. Eighteen of the patients had signs of an expansive process within the cavity, the vessels being displaced and stretched around the lesions.

    TODOS: Estudio retrospectivo multicéntrico de cohortes realizado en el período del 2005 al 2008 en 16 instituciones de atención de salud de referencia públicas y privadas de Bogotá, Colombia, que forman parte de una red nacional de vigilancia epidemiológica y de una red hospitalaria de 4 469 camas. Se analizaron la aparición de resistencia a la meticilina y la mortalidad mediante análisis descriptivos y de tiempo transcurrido hasta un suceso; se estableció un modelo multifactorial de regresión de riesgos proporcionales de Cox para evaluar la asociación entre la resistencia a la meticilina y la mortalidad. RESULTADOS: Se estudiaron 372 pacientes: 186 con bacteriemia por MRSA, apareados aleatoriamente con 186 con bacteriemia por Staphylococcus aureus sensible a la meticilina (MSSA. La cirugía previa, el tratamiento con antibióticos y las infecciones intrahospitalarias se asociaron independientemente con la resistencia a la meticilina. El MRSA provocó hospitalizaciones más prolongadas en los sobrevivientes (mediana de 24 frente a 18 días, P = 0,014. Los factores predictivos de mortalidad fueron: la edad del paciente, un nivel de creatinina superior a 1,21 mg/dl al ingresar en la UCI, la septicemia grave y el requerimiento de inotrópicos. El tratamiento antimicrobiano apropiado y el cambio de tratamiento antimicrobiano constituyeron factores protectores independientes, igual que el sexo masculino. CONCLUSIONES: La resistencia a la meticilina per se no fue un factor pronóstico independiente de la mortalidad. Las condiciones previas, como la edad, la insuficiencia renal inicial, la septicemia grave y el requerimiento de inotrópicos explicaron la mortalidad observada. El tratamiento antimicrobiano apropiado seguía siendo un factor protector. Es obligatorio hacer un llamamiento para mejorar las medidas de control de las infecciones en Colombia y en otros contextos similares.

    Full Text Available El poliomavirus humano BK causa infección primaria asintomática en la niñez, estableciendo latencia principalmente en el tracto urinario. En individuos con alteración en la inmunidad celular se puede producir su reactivación desencadenando patología a nivel renal. Por estas razones es particularmente importante en la población pediátrica trasplantada renal, en la que puede producir la infección primaria cuando el paciente está inmunosuprimido. En nuestro trabajo se realizó el seguimiento de un paciente de 5 años trasplantado renal en octubre de 2003 que 45 días post-trasplante sufrió un deterioro del órgano injertado. Desde la fecha del trasplante hasta junio de 2004 se produjeron 3 episodios de alteración en la función renal, durante los cuales se analizaron muestras de sangre, orina, biopsia renal y líquido de linfocele. Para el diagnóstico difererencial entre rechazo agudo versus causa infecciosa se emplearon técnicas de detección para los virus BK, CMV y ADV, además del estudio citológico del tejido renal. Los resultados obtenidos junto con la clínica del paciente indican un probable caso de infección por BK. La importancia de realizar el diagnóstico diferencial entre rechazo agudo y la infección por BK radica en que la conducta en cuanto a la terapia inmunosupresora es opuesta en cada caso.BK Human Polyomavirus causes an asymptomatic primary infection in children, then establishing latency mainly in the urinary tract. Viral reactivation can lead to renal pathology in individuals with impaired cellular immune response.

  12. RENAL DAMAGE WITH MALIGNANT NEOPLASMS

    Full Text Available The relationship between renal damage and malignant neoplasms is one of the most actual problems of the medicine of internal diseases. Very often, exactly availability of renal damage determines the forecast of cancer patients. The range of renal pathologies associated with tumors is unusually wide: from the mechanical effect of the tumor or metastases on the kidneys and/or the urinary tract and paraneoplastic manifestations in the form of nephritis or amyloidosis to nephropathies induced with drugs or tumor lysis, etc. Thrombotic complications that develop as a result of exposure to tumor effects, side effects of certain drugs or irradiation also play an important role in the development of the kidney damage. The most frequent variants of renal damage observed in the practice of medical internists (therapists, urologists, surgeons, etc., as well as methods of diagnosis and treatment approaches are described in the article. Timely and successful prevention and treatment of tumor-associated nephropathies give hope for retaining renal functions, therefore, a higher life standard after completion of anti-tumor therapy. Even a shortterm episode of acute renal damage suffered by a cancer patient must be accompanied with relevant examination and treatment. In the caseof transformation of acute renal damage into the chronic kidney disease, such patients need systematic and weighted renoprotective therapy and correct dosing of nephrotoxic drugs.

    2014-01-01

    Teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. Teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. A left-sided abdominal mass was detected on physical examination and B-Mod Ultrasound (US) examination revealed a heterogeneous mass with central cystic component. Computed tomography (CT) demonstrated a lobulated, heterogeneous, hypodense mass extending craniocaudally from the splenic hilum to the level of the left iliac fossa. Nephrectomy was performed and a large, fatty mass arising from the left kidney was excised. The final pathologic diagnosis was confirmed as cystic renal teratoma

    Yuen, Noah K; Ananthakrishnan, Shubha; Campbell, Michael J

    2016-01-01

    Renal hyperparathyroidism (rHPT) is a common complication of chronic kidney disease characterized by elevated parathyroid hormone levels secondary to derangements in the homeostasis of calcium, phosphate, and vitamin D. Patients with rHPT experience increased rates of cardiovascular problems and bone disease. The Kidney Disease: Improving Global Outcomes guidelines recommend that screening and management of rHPT be initiated for all patients with chronic kidney disease stage 3 (estimated glomerular filtration rate, < 60 mL/min/1.73 m(2)). Since the 1990s, improving medical management with vitamin D analogs, phosphate binders, and calcimimetic drugs has expanded the treatment options for patients with rHPT, but some patients still require a parathyroidectomy to mitigate the sequelae of this challenging disease.

    Rickets/osteomalacia is an important problem in a tropical country. Many cases are due to poor vitamin D intake or calcium deficient diets and can be corrected by administration of calcium and vitamin D. However, some cases are refractory to vitamin D therapy and are related to renal defects. These include rickets of renal tubular acidosis (RTA), hypophosphatemic rickets, and vitamin D dependent rickets (VDDR). The latter is due to impaired action of 1α-hydroxylase in renal tubule. These varieties need proper diagnosis and specific treatment. PMID:24251212

    There are differences in renal anatomy and physiology between rabbits and other domestic species. Neurogenic renal ischemia occurs readily. Reversible prerenal azotemia may be seen in conjunction with gut stasis. Potentially fatal acute renal failure may be due to structural kidney damage or post-renal disease. Chronic renal failure is often associated with encephalitozoonosis. Affected rabbits cannot vomit and often eat well. Weight loss, lethargy, and cachexia are common clinical signs. Polydypsia/polyuria may be present. Derangements in calcium and phosphorus metabolism are features of renal disease. Radiography is always indicated. Urolithiasis, osteosclerosis, aortic and renal calcification are easily seen on radiographs. Copyright © 2013 Elsevier Inc. All rights reserved.

    2006-01-01

    Objective: To study the relationship between renal morphology and renal function, and to assess the value of CT as a criterion to grade renal function. Methods: Enhancement CT were performed in 89 patients with no local renal disease whose split renal glomerular filtration rates (GFR) were measured by renal dynamic imaging with 99 Tc m -DTPA. The 178 kidneys were divided into normal renal function, mild and severe renal impairment groups according to renal function. Differences between three groups respect to the mean thickness of renal cortex and parenchyma were assessed by ANOVA. Using Pearson's correlation test, the correlation between the renal cortex, parenchyma thicknesses and renal GFR were examined. The value of CT in predicting renal function was assessed by using ROC analysis. Results: The renal cortex thicknesses of normal renal function, mild and severe renal impairment groups were (5.9±1.1), (4.6± 1.1), and (3.3±1.0) mm respectively, and the renal parenchyma thicknesses were (26.3±4.2), (21.3±4.6), (16.2±4.6) mm. There were significant differences of renal cortex, parenchyma thicknesses between 3 groups (cortex F=54.78, P<0.01; parenehyma F=43.90, P<0.01). The thicknesses of renal cortex (r=0.752, P<0.01), parenchyma (r=0.738, P<0.01) had positive linear correlation with renal function. ROC analysis of the renal cortex thicknesses measured by CT in predicting mild and severe renal impairment showed that the Az was 0.860 and 0.905 respectively, whereas that of parenchyma was 0.868 and 0.884. Conclusion: The thicknesses of renal cortex, parenchyma measured by CT can reflect renal function. CT was a supplementary method to assess renal function. (authors)

  7. The Effects of Renal Denervation on Renal Hemodynamics and Renal Vasculature in a Porcine Model.

    Willemien L Verloop

    Full Text Available Recently, the efficacy of renal denervation (RDN has been debated. It is discussed whether RDN is able to adequately target the renal nerves.We aimed to investigate how effective RDN was by means of functional hemodynamic measurements and nerve damage on histology.We performed hemodynamic measurements in both renal arteries of healthy pigs using a Doppler flow and pressure wire. Subsequently unilateral denervation was performed, followed by repeated bilateral hemodynamic measurements. Pigs were terminated directly after RDN or were followed for 3 weeks or 3 months after the procedure. After termination, both treated and control arteries were prepared for histology to evaluate vascular damage and nerve damage. Directly after RDN, resting renal blood flow tended to increase by 29±67% (P = 0.01. In contrast, renal resistance reserve increased from 1.74 (1.28 to 1.88 (1.17 (P = 0.02 during follow-up. Vascular histopathology showed that most nerves around the treated arteries were located outside the lesion areas (8±7 out of 55±25 (14% nerves per pig were observed within a lesion area. Subsequently, a correlation was noted between a more impaired adventitia and a reduction in renal resistance reserve (β: -0.33; P = 0.05 at three weeks of follow-up.Only a small minority of renal nerves was targeted after RDN. Furthermore, more severe adventitial damage was related to a reduction in renal resistance in the treated arteries at follow-up. These hemodynamic and histological observations may indicate that RDN did not sufficiently target the renal nerves. Potentially, this may explain the significant spread in the response after RDN.

    Bone scintigraphy with Tc-99m HEDP was performed in 30 patients on maintenance hemodialysis, and the results of quantitative analysis were compared wth those of a normal group. To permit this comparison, elevated background activity due to the absence of renal radiotracer excretion was reduced by hemodialysis to levels found in the normals. Histologic proof of renal osteodystrophy had been obtained in all patients. the incidence of radiographic abnormalities was 46%, whereas abnormal scans were found in 25 patients (83%); skeletal lesions were also more pronounced and detected earlier. However, even when the scans appeared normal, the quantitative analysis showed increased skeletal activity in all patients. The total skeletal activity proved to be a good index of the severity of renal osteodystrophy and appeared dependent on both osteomalacia and hyperparathyroidism. These findings show that bone scintigraphy is a sensitive method to detect skeletal involvement in renal osteodystrophy

    2016-05-01

    Prolonged intermittent renal replacement therapy (PIRRT) is becoming an increasingly popular alternative to continuous renal replacement therapy in critically ill patients with acute kidney injury. There are significant practice variations in the provision of PIRRT across institutions, with respect to prescription, technology, and delivery of therapy. Clinical trials have generally demonstrated that PIRRT is non-inferior to continuous renal replacement therapy regarding patient outcomes. PIRRT offers cost-effective renal replacement therapy along with other advantages such as early patient mobilization and decreased nursing time. However, due to lack of standardization of the procedure, PIRRT still poses significant challenges, especially pertaining to appropriate drug dosing. Future guidelines and clinical trials should work toward developing consensus definitions for PIRRT and ensure optimal delivery of therapy. Copyright © 2016 National Kidney Foundation, Inc.

    Fungal infection is relatively common among renal transplant recipients from developing countries. Mucormycosis, also known as zygomycosis, is one of the most serious fungal infections in these patients. The most common of presentation is rhino-cerebral. Isolated involvement of a renal allograft is very rare. A thorough search of literature and our medical records yielded a total of 24 cases with mucormycosis of the transplanted kidney. There was an association with cytomegalovirus (CMV) infection and anti-rejection treatment in these patients and most of these transplants were performed in the developing countries from unrelated donors. The outcome was very poor with an early mortality in 13 (54.5%) patients. Renal allograft mucormycosis is a relatively rare and potentially fatal complication following renal transplantation. Early diagnosis, graft nephrectomy and appropriate antifungal therapy may result in an improved prognosis for these patients. PMID:26069793

    2008-07-01

    The study of renal atherosclerotic disease has conventionally focused on the diagnosis and management of renal artery stenosis. With the increased understanding of atherosclerosis as a systemic inflammatory process, there has been increased interest in vascular biology at the microvasculature level. While different organ beds share some features, the inflammation and injury in the microvasculature of the kidney has unique elements as well. Understanding of the pathogenesis yields a better understanding of the clinical manifestations of renal atherosclerotic disease, which can be very subtle. Furthermore, identifying the molecular mechanisms responsible for the progression of kidney damage can also direct clinicians and scientists toward targeted therapies. Existing therapies used to treat atherosclerotic disease in other vascular beds may also play a role in the treatment of renal atherosclerotic disease.

  2. Renal Ammonia Metabolism and Transport

    Science.gov (United States)

    Weiner, I. David; Verlander, Jill W.

    2015-01-01

    Renal ammonia metabolism and transport mediates a central role in acid-base homeostasis. In contrast to most renal solutes, the majority of renal ammonia excretion derives from intrarenal production, not from glomerular filtration. Renal ammoniagenesis predominantly results from glutamine metabolism, which produces 2 NH4+ and 2 HCO3− for each glutamine metabolized. The proximal tubule is the primary site for ammoniagenesis, but there is evidence for ammoniagenesis by most renal epithelial cells. Ammonia produced in the kidney is either excreted into the urine or returned to the systemic circulation through the renal veins. Ammonia excreted in the urine promotes acid excretion; ammonia returned to the systemic circulation is metabolized in the liver in a HCO3−-consuming process, resulting in no net benefit to acid-base homeostasis. Highly regulated ammonia transport by renal epithelial cells determines the proportion of ammonia excreted in the urine versus returned to the systemic circulation. The traditional paradigm of ammonia transport involving passive NH3 diffusion, protonation in the lumen and NH4+ trapping due to an inability to cross plasma membranes is being replaced by the recognition of limited plasma membrane NH3 permeability in combination with the presence of specific NH3-transporting and NH4+-transporting proteins in specific renal epithelial cells. Ammonia production and transport are regulated by a variety of factors, including extracellular pH and K+, and by several hormones, such as mineralocorticoids, glucocorticoids and angiotensin II. This coordinated process of regulated ammonia production and transport is critical for the effective maintenance of acid-base homeostasis. PMID:23720285

    The authors report their experience in the study of renal transplant recipients by MR, in order to determine its clinical potentials. The main purpose of this work is to focus on MR patterns in relation to clinical findings of rejector or normally fuctioning kidney. Twenty-four patients were examined with a 0.5 T superconductive magnete, body coil, spin-echo pulse sequence (SE) and inversion-recovery (IR). MRI patterns could be seen in normally functioning kidneys and transplant rejections, while variable MRI findings were observed in transplants with acute tubular necrosis (ATN). In the normally functioning transplanted kidney there is a clear corticomedullary differentiation (CMD), and the extent of vascular penetration into the renal parenchyma is clearly seen. In transplant rejection, CMD is either diminished or absent, and there is no vascular penetration into the parenchyma; to differentiate acute from chronic rejections, the increase/decrease in renal size and the change in renal shape (spherical shape in acute transplant rejection) respectively must be observed. MRI proves thus to be useful in the study of renal transplants, even in case of questionable clinical findings, and in patients in whom renal biopsy is contraindicated

    Renal transplantation is the most effective mode of renal replacement therapy for correction of renal failure. Renal donors can either be: a. a deceased person - the kidneys being removed when brain death or absence of cerebral cortical function / perfusion is confirmed - the cadaveric kidney is packed in ice and nutrient solution and transplanted within 24 hours of removal ('cold ischemia') ob. a living donor - the donor may or may not be related to the recipient. Due to the limited length of the renal vessels and ureter of the donor kidney, it is implanted close to the bladder of the recipient. The donor vessels are anastomosed to the iliac artery and vein of the recipient. Transplant variants: a. 2 kidneys maybe transplanted because: - an old donor with less kidney reserve from atrophy due to age or disease (e.g. hypertension) - an infant donor when both kidneys are removed en bloc, b. Donor kidneys with more than 1 artery, vein or ureter. c. Donor horse shoe kidney d. Combined renal and pancreas transplant for type I diabetics -a short segment of duodenum transplanted with the pancreas maybe implanted into the bladder.

    Acute renal failure (ARF) occurs in up to 10% of critically ill patients, with significant associated morbidity and mortality. The optimal mode of renal replacement therapy (RRT) remains controversial. This retrospective study compared continuous renal replacement therapy (CRRT) and intermittent hemodialysis (IHD) for RRT in terms of intensive care unit (ICU) and hospital mortality, and renal recovery. We reviewed the records of all patients undergoing RRT for the treatment of ARF over a 12-month period. Patients were compared according to mode of RRT, demographics, physiologic characteristics, and outcomes of ICU and hospital mortality and renal recovery using the Chi square, Student's t test, and multiple logistic regression as appropriate. 116 patients with renal insufficiency underwent RRT during the study period. Of these, 93 had ARF. The severity of illness of CRRT patients was similar to that of IHD patients using APACHE II (25.1 vs 23.5, P = 0.37), but they required significantly more intensive nursing (therapeutic intervention scale 47.8 vs 37.6, P = 0.0001). Mortality was associated with lower pH at presentation (P = 0.003) and increasing age (P = 0.03). Renal recovery was significantly more frequent among patients initially treated with CRRT (21/24 vs 5/14, P = 0.0003). Further investigation to define optimal timing, dose, and duration of RRT may be beneficial. Although further study is needed, this study suggests that renal recovery may be better after CRRT than IHD for ARF. Mortality was not affected significantly by RRT mode.

    Alagille syndrome (AS) is a cholestatic disease secondary to scarcity of interlobular bile ducts. It is associated with extrahepatic manifestations, and renal involvement is frequent. To describe the prevalence, type and outcome of renal pathology in children with AS. The presence and outcome of renal pathology was retrospectively studied in 21 children who met AS criteria. Renal pathology was observed in 18 patients (85.7%): (1) ultrasound variations in 7 patients (6 cases of bilateral renal dysplasia and 1 case of renal agenesis); (2) distal renal tubular acidosis in 2 patients; (3) a drop in glomerular filtration and/or proteinuria in 16 patients. The frequency of a drop in glomerular filtration was similar between patients with and without pathological kidney ultrasound findings. Our study confirms a high prevalence of renal involvement, which enhances the importance of diagnosis and renal function follow-up in children with AS. Sociedad Argentina de Pediatría.

    Renal dysfunction is encountered in 20-25% of patients with multiple myeloma (MM) at the time of diagnosis. There is often a precipitating event. Several biochemical and clinical correlations with renal failure in MM have been reported. Renal failure in MM is associated with worse outcome of the disease. We retrospectively analyzed the medical records of 64 patients with MM admitted to our institution during the period January 1992 to December 2012. Abnormal renal function was observed in 24 (37.5%) patients and 17 (26.6%) of them had renal failure; 14 of the 17 (82.4%) of patients with renal failure had Stage III MM. Urine Bence- Jones protein was positive in ten (58.8%) patients with renal failure versus ten (21.3%) patients without renal failure (P = 0.004). Potential precipitating factors of renal failure were determined in nine patients. Renal function normalized in 11 patients with simple measures, while six patients required hemodialysis; one remained dialysis dependent till time of death. Early mortality occurred in five (29.4%) patients with renal failure as compared with two (4.3%) patients in the group without renal failure (P = 0.005). In conclusion, renal failure is associated with a higher tumor burden and Bence-Jones proteinuria in patients with MM. It is reversible in the majority of patients; however, early mortality tends to be higher in patients with persistent renal failure.

    Renal failure secondary to ANCA-associated vasculitis represents a clinical and therapeutic challenge. In this study, we aimed to assess the treatment response rates and long-term outcomes of vasculitis patients presenting with renal failure. This retrospective study included 151 patients with renal vasculitis from three hospitals who underwent a renal biopsy between 1997 and 2014. Patients with renal failure which required dialysis at the onset were compared to those presenting with more preserved renal function. The primary end point was treatment response and patient surivival. Patients with severe renal involvement had a lower response to treatment compared to those having preserved renal function (26.6 versus 93.4%; p renal recovery (41.6 versus 12.5%; p = 0.05). A higher incidence of severe infections was observed among patients with severe renal involvement (38.4 versus 18.1%, p = 0.01). The mortality rate was significantly higher among vasculitis patients presenting with renal failure (53.8 versus 22.2%, p = 0.001). Global survival at 1 and 5 years was 60 and 47% in patients requiring dialysis compared with 90 and 80% among those with more preserved renal function (p renal dysfunction represents an independent risk factor for patient survival in renal vasculitis. Patients requiring dialysis associate a lower response rate to immunosuppressive therapy and a higher incidence of severe infections.

    1987-01-01

    This study was designed to investigate the hemodynamic effects of exogenous adenosine in the interstitium of the rat kidney. Adenosine or its analogues were infused into the renal interstitium by means of chronically implanted capsules. In fusion of adenosine decreased glomerular filtration rate (GFR) from 0.81 +/- 0.06 to 0.37 +/- 0.06 ml/min while having no effect on renal blood flow (RBF). The metabolically stable analogue, 2-chloradenosine (2-ClAdo), decreased GFR from 0.73 +/- 0.07 to 021 +/- 0.06 ml/min. Interstitial infusion of theophylline, an adenosine receptor antagonist, completely abolished the effects of adenosine and 2-ClAdo on GFR. The distribution of adenosine, when infused into the renal interstitium, was determined using radiolabeled 5'-(N-ethyl)-carboxamidoadenosine (NECA), a metabolically stable adenosine agonist. After continuous infusion, [ 3 H]NECA was distributed throughout the kidney. The effects of NECA to reduce GFR were similar to those of adenosine and 2-ClAdo. They conclude that increased levels of adenosine in the renal interstitium markedly decrease GFR without affecting RBF in steady-state conditions. The marked effects of adenosine agonists during their infusion into the renal interstitium and the complete blockade of these effects by theophylline suggest an extracellular action of adenosine

Cortex, outer medulla and inner medulla were delineated and their sequential CT image was well correlated with the anatomicophysiological character of the kidney. Dynamic CT of 32 abnormal cases showed abnormal sequential CT findings explaining the mechanism of the abnormalities. Especially, delayed enhancement of renal cortex was noted in 17 of 19 kidneys with arterial obstruction and delayed enhancement of renal medulla in 22 of 25 cases with renal dysfunction. Compaired with excretory urography in 11 cases with renal dysfunction, advantage of dynamic CT were noted. (author)

    Most renal lesions replace the renal parenchyma as a focal space-occupying mass with borders distinguishing the mass from normal parenchyma. However, some renal lesions exhibit interstitial infiltration-a process that permeates the renal parenchyma by using the normal renal architecture for growth. These infiltrative lesions frequently show nonspecific patterns that lead to little or no contour deformity and have ill-defined borders on CT, making detection and diagnosis challenging. The purpose of this pictorial essay is to describe the CT imaging findings of various conditions that may manifest as infiltrative renal lesions.

The purpose of this study was to assess the differences of CT findings between two conditions. CT findings of 5 cases of renal cell carcinoma involving the renal collecting systems and 10 cases of renal urothelial tumors invading the renal parenchyma were compared, and analyzed about the presence or absence of hydronephrosis, normal or abnormal CT nephrogram, renal contour changes due to mass and tentative diagnosis. The diagnoses were confirmed at surgery. Renal cell carcinoma showed hydronephrosis in only 20% and normal CT nephrogram and outward contour bulging in all cases. In contrast, renal urothelial tumor showed hydronephrosis(70%), abnormal CT nephrogram(60%), and preservation of reinform shape(100%). Renal contour changes and CT nephrogram may be useful in distinguishing both disease entities

    Eleven patients with sharply circumscribed round to ovoid renal cysts measuring 70-90 H on CT are reported. The cysts were hyperdense on unenhanced scans, measuring 30-60 H greater than the adjacent parenchyma, and either hypodense, isodense, or hyperdense on enhanced scans. Four patients had polycystic kidney disease; of the other 7 patients, the cysts were cortical in 6 and parapelvic in 1. Eight patients had a solitary cyst and 3 had multiple cysts. Sonography demonstrated internal echoes and/or lack of increased through-transmission in 6 patients. Pathological analysis was available in 6 cases and indicated a benign, hemorrhagic renal cyst. This hyperdense CT appearance is characteristic of some hemorrhagic renal cysts, though differentiation between benign and malignant cysts requires cyst puncture and/or surgery

    To report two cases of renal hemorrhage after extracorporeal shock wave lithotripsy (ESWL) and their therapeutic management. Description of the clinical cases, together with the diagnosis and therapeutic management of these complications. We present two cases of patients with renal hemorrhage after ESWL, which were performed without immediate complications. One of the cases, after detecting an important laceration of the renal parenchyma, needed two embolization sessions for its short-term resolution; however, the patient finally passed away due to the complications derived from hemorrhage. The other case was solved through conservative management. Even though hemorrhage is an infrequent complication after ESWL, it should be suspected when the patient presents compatible clinical symptoms, since even though most cases are resolved in a conservative manner, on some occasions specific treatments for the hemorrhage are necessary. Old age and the presence of vascular comorbidities seem to be related to a higher risk of hemorrhage after ESWL.

    Data on renal hemodynamics, function, and oxygenation in early clinical septic shock are lacking. We therefore measured renal blood flow, glomerular filtration rate, renal oxygen consumption, and oxygenation in patients with early septic shock. Prospective comparative study. General and cardiothoracic ICUs. Patients with norepinephrine-dependent early septic shock (n = 8) were studied within 24 hours after arrival in the ICU and compared with postcardiac surgery patients without acute kidney injury (comparator group, n = 58). None. Data on systemic hemodynamics and renal variables were obtained during two 30-minute periods. Renal blood flow was measured by the infusion clearance of para-aminohippuric acid, corrected for renal extraction of para-aminohippuric acid. Renal filtration fraction was measured by renal extraction of chromium-51 labeled EDTA. Renal oxygenation was estimated from renal oxygen extraction. Renal oxygen delivery (-24%; p = 0.037) and the renal blood flow-to-cardiac index ratio (-21%; p = 0.018) were lower, renal vascular resistance was higher (26%; p = 0.027), whereas renal blood flow tended to be lower (-19%; p = 0.068) in the septic group. Glomerular filtration rate (-32%; p = 0.006) and renal sodium reabsorption (-29%; p = 0.014) were both lower in the septic group. Neither renal filtration fraction nor renal oxygen consumption differed significantly between groups. Renal oxygen extraction was significantly higher in the septic group (28%; p = 0.022). In the septic group, markers of tubular injury were elevated. In early clinical septic shock, renal function was lower, which was accompanied by renal vasoconstriction, a lower renal oxygen delivery, impaired renal oxygenation, and tubular sodium reabsorption at a high oxygen cost compared with controls.

    Full Text Available The purpose of this study was to carry out a five-year retrospective descriptive follow-up of the oral manifestation frequency, systemic condition and type of medication used in HIV-infected children and adolescents after the introduction of combined antiretroviral therapy. Fifty-eight patients were examined in 2001/2002, and their previous medical and dental records (1997 to 2000 were researched from files. There was an occurrence of 7 new cases of AIDS in a sample of 19 children, while 46.5% of the entire sample (n = 58 progressed as to classification of HIV infection. No difference was noted among the frequencies of oral manifestations, categories of the immunosuppression and viral load categories. The oral manifestations in the group of children and adolescents followed up in this study remained stable, even after treatment with combined antiretroviral therapy. However, a downward trend in the frequency of oral candidiasis and parotid enlargement was noted.O objetivo deste estudo foi realizar um acompanhamento descritivo retrospectivo da freqüência de manifestações bucais, da condição sistêmica e do tipo de medicação utilizada em um grupo de crianças e adolescentes infectados pelo HIV após a introdução da terapia anti-retroviral combinada.

    It was demonstrated in rats that renal injury which follows transient renal hypoxia is potentiated by the contrast media metrizoate, ioxaglate, iopamidol and iohexol. Intravenous injection of 1 g I/kg of all four media alone to 82 rats caused no significant increase in serum urea 1, 3 and 7 days later. The percentage increase of serum urea is given in median values and interquartile range (in parentheses). Bilateral renal arterial occlusion alone for 40 minutes in 42 rats increased serum urea one day later by 40% (20-130). Intravenous injection of the media followed in one hour by bilateral renal arterial occlusion for 40 minutes in 104 rats caused serum urea to increase one day later by 130% (70-350) after metrizoate, by 220% (50-380) after ioxaglate, by 290 % (60-420) after iopamidol and by 160% (50-330) after iohexol. There were no significant differences between the potentiating effects of the various media on ischemic renal failure. (orig.)

    All reported cases of massive postpartum right renal hemorrhage have involved healthy young primigravidas and blacks have predominated (4 of 7 women). Coagulopathies and underlying renal disease have been absent. Hematuria was painless in 5 of 8 cases. Hemorrhage began within 24 hours in 1 case, within 48 hours in 4 cases and 4 days post partum in 3 cases. Our first case is the only report in which hemorrhage has occurred in a primipara. Failure of closure or reopening of pyelovenous channels is suggested as the pathogenesis. The hemorrhage has been self-limiting, requiring no more than 1,500 cc whole blood replacement. Bleeding should stop spontaneously, and rapid renal pelvic clot lysis should follow with maintenance of adequate urine output and Foley catheter bladder decompression. To date surgical intervention has not been necessary.

    Full Text Available Myxomas are mesenchymal tumors commonly found in the heart and skin. Renal myxomas are rare, having only been documented 14 times. Our case is a 55-year-old woman who presented to our clinic after a right renal mass was incidentally found on CT. Evaluation with MRI showed a mass that appeared to arise from the supero-medial cortex of the right kidney. As the imaging was concerning for renal cell carcinoma, the patient underwent a partial nephrectomy. Microscopic examination showed a well-circumscribed mass with polygonal to spindle-shaped cells in a granular eosinophilic cytoplasm. Immunohistochemical staining for CD-10, Desmin, HMB-45, and Pankeratin were negative.

    We have five cases of the global renal infarction, four of which resulted from post-transarterial embolization(TAE) of the hypernephroma, the remaining one was probably caused by the cardiac disease. Generally speaking, CE-CT is useful for the diagnosis of the acute renal infarction, because the ''rim sign'' which represents viable subcapsular parenchyma is helpful for the diagnosis. It seems that band-like enhancement from the renal sinus to the periphery in the low-attenuation-parenchyma on CE-CT, named as ''band sign'', is useful for the diagnosis. ''Band sign'' may also be valuable for distinguishing the neoplastic area from the non-neoplastic one after TAE of the hypernephroma. (author)

    Radiographic findings of thirty eight cases of renal tuberculosis treated at this hospital during last 4 years were analysed with following results. The cases examined were 24 male and 14 female patients. Age distribution was broad and evenly distributed ranging from 2nd decades to 5th decades. Main symptoms complained were urinary frequency, hematuria, dysuria and flank pain. Findings of physical examination revealed tenderness of costovertebral angle, palpable mass on flank area and epididymal indutration. The simple chest films showed pulmonary tuberculosis in 22 cases including 6 cases of active military type. Thirty one cases showed increased ESR, 8 cases showed AFB positive in urine and 12 cases showed bilateral renal tuberculosis. Through urographic findings nonvisualization, cyceopelviectasis, motheaten appearance of minor calyx, contracted bladder, delayed visualization, ureteral stricture and beading were observed in order of frequency. Five cases with miliary tuberculosis showed advanced renal lesion on urogram

    CT is indispensable in the evaluation of renal masses, providing noninvasive and clear transverse images. With wider clinical application of CT, renal cysts have been found more frequently. CT examinations on 500 patients, who underwent CT for the diagnosis of renal diseases except for renal cysts, have been reviewed and analysed. The incidence of renal cysts was 9.6 % without prediction for sexes, but the incidence and sizes of the cysts increased with the advancing age. The upper portion of the kidneys was more frequently involved, but there was no relationship between number, sex and age of the patients. Since renal cysts produce mass effect in the kidneys, understanding of the nature and incidence of the renal cysts is important in diagnosing renal mass lesions. (author)

    The radionuclide dynamic and function study, glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) were reported in 14 cases of renal and ureteral calculi patients before and after extracorporeal shock wave lithotripsy (ESWL). In 12 cases with normal renal blood flow, within 3 months after ESWL, the GFR of shock and non-shock side decreased with different extent, while the individual ERPF had little change. In 5 cases followed up 1 year after ESWL, the individual GFR and ERPF were normal. In 2 cases of severe renal function insufficiency, there was no improvement in renal function in shock side, after 5 months and 1 year, the renal function was still at low level. Thereby it is considered that ESWL is not suitable for the renal calculi patients with severe renal function insufficiency

    To study the effects of renal failure on bumetanide kinetics, the authors administered single intravenous doses of 1.0 mg/3.08 microCi 14 C-bumetanide to six healthy subjects and 22 patients with variable degrees of renal failure. The kinetics of 14 C-bumetanide and total 14 C were adequately described by a two-compartment open model in the control subjects and in the patients. The volume of the central compartment and the distribution t1/2 were of the same order in both groups, whereas the mean (+/- SE) volume at steady state was larger (22.1 +/- 1.6 and 16.9 +/- 1.0 L) and the elimination t1/2 was longer (1.9 +/- 0.2 and 1.4 +/- 0.1 hours) in patients with renal failure than in healthy controls. Bumetanide renal clearance was lower (10 +/- 3 and 90 +/- 13 ml/min) in patients than in subjects and correlated with creatinine clearance (r = 0.784) and log serum creatinine level (r = -0.843), whereas nonrenal clearance was significantly higher in the patients (153 +/- 14 and 99 +/- 6 ml/min). Bumetanide total plasma clearance did not significantly change. The non-protein-bound, free fraction of bumetanide was higher in patients and correlated with plasma albumin levels (r = -0.777). The kinetics of total 14 C showed similar but greater changes than those of 14C-bumetanide. Thus the most important changes in bumetanide kinetics in patients with renal failure are low renal clearance and a high free fraction, with a consequent increase in nonrenal clearance, volume of distribution, and elimination t1/2

  7. Molecular mechanisms of renal aging.

    Schmitt, Roland; Melk, Anette

    2017-09-01

    Epidemiologic, clinical, and molecular evidence suggest that aging is a major contributor to the increasing incidence of acute kidney injury and chronic kidney disease. The aging kidney undergoes complex changes that predispose to renal pathology. The underlying molecular mechanisms could be the target of therapeutic strategies in the future. Here, we summarize recent insight into cellular and molecular processes that have been shown to contribute to the renal aging phenotype.The main clinical finding of renal aging is the decrease in glomerular filtration rate, and its structural correlate is the loss of functioning nephrons. Mechanistically, this has been linked to different processes, such as podocyte hypertrophy, glomerulosclerosis, tubular atrophy, and gradual microvascular rarefaction. Renal functional recovery after an episode of acute kidney injury is significantly worse in elderly patients. This decreased regenerative potential, which is a hallmark of the aging process, may be caused by cellular senescence. Accumulation of senescent cells could explain insufficient repair and functional loss, a view that has been strengthened by recent studies showing that removal of senescent cells results in attenuation of renal aging. Other potential mechanisms are alterations in autophagy as an important component of a disturbed renal stress response and functional differences in the inflammatory system. Promising therapeutic measures to counteract these age-related problems include mimetics of caloric restriction, pharmacologic renin-angiotensin-aldosterone system inhibition, and novel strategies of senotherapy with the goal of reducing the number of senescent cells to decrease aging-related disease in the kidney.

    Full Text Available En este ensayo resaltamos los vínculos cognitivos entre las matemáticas y la música, que pueden favorecer procesos de enseñanza y aprendizaje de las fracciones en la matemática escolar. Las actividades exhibidas provienen de una investigación que promueve experiencias sensoriales en el campo rítmico para favorecer la construcción de nociones matemáticas. Dichas actividades posibilitan un engranaje armónico entre las matemáticas y la música convergentes en el tiempo y el sonido como los objetos de estudio común entre éstas disciplinas. El análisis de la investigación que aquí reportamos es producto de la aplicación de las actividades en diferentes programas de formación de profesorado de México y Francia, alrededor de la enseñanza y aprendizaje de las matemáticas en contextos interdisciplinarios. Este análisis se desarrolló desde tres categorías referentes a las nociones de unidad relativa, relación parte-parte y equipartición, las cuales son nociones fundamentales para el estudio de las fracciones en la matemática escolar. Encontramos que la enseñanza con enfoque integrador requiere no solo conocimientos especializados, sino un cambio de creencias en torno a las opiniones del profesorado sobre la organización del currículo, su enseñanza y la manera en que aprende la población estudiantil. Un aporte de esta experiencia es ofrecer a docentes elementos teóricos y didácticos para el estudio de las fracciones en contextos interdisciplinarios.

    Radioisotopic renal function tests are of assistance to diagnose and follow-up the course of renal insufficiency. The radioisotopic renogram is useful in assessing the response to therapy of child obstructive uropathies and evaluating renal transplant function. The renal scan is helpful, in an emergency service, to differenciate chronic renal insufficiency from acute renal insufficiency. Hg renal uptake test provides informations on physiopathological problems. Among them, the following problems are emphasized: evolution of a nonfunctioning kidney, control of the success of a reparative surgery and of bilateral obstructive uropathies with unilateral symptoms [fr

    Acute renal infarction presents in a similar clinical picture to that of a renal stone. We report a 55-year-old Saudi female, known to have atrial fibrillation secondary to mitral stenosis due to rheumatic heart disease. She presented with a two day history of right flank pain that was treated initially as renal stone. Further investigations confirmed her as a case of renal infarction. Renal infarction is under-diagnosed because the similarity of its presentation to renal stone. Renal infarction should be considered in the differential diagnosis of loin pain, particularly in a patient with atrial fibrillation. (author)

    In order to determine sonographic characteristic of renal tuberculosis, we retrospectively collected 27 cases during a 5 year period. Infected kidneys showed large size (52%) and lobulating contour (76%). In 19 cases of increased parenchymal echogenicity, most of them (16 cases) showed decreased parenchymal thickness. We divided hydronephrotic patterns into 4 categories; predominant calyceal dilatation with mild or no pelvic dilatation (67%), focal calyectasis without pelvic dilation (15%), parenchymal cavitation without hydronephrosis (11%) and proportional hydronephrosis with calyceal deformity (7%). Our findings suggest that disproportional hydronephrosis would be the characteristic finding of renal tuberculosis

  16. Rol de las claudinas en el manejo renal del calcio

    Full Text Available Los canales paracelulares que se encuentran en las uniones estrechas tienen un papel fundamental en los flujos iónicos transepiteliales. Esta vía está formada por un gran número de proteínas, entre ellas, las claudinas. En el epitelio renal, las claudinas confieren selectividad iónica a la unión estrecha. La rama gruesa ascendente de Henle (RGAH es el segmento tubular renal más importante en la reabsorción tubular de calcio. Sus células forman una barrera impermeable al agua, transportan activamente sodio y cloro por la vía transcelular y proveen una vía paracelular para la reabsorción selectiva de calcio. Varios estudios han llevado a un modelo en el que distintas claudinas forman el canal paracelular, especialmente la claudina 16 y 19. La claudina 16 media la permeabilidad paracelular catiónica en la RGAH mientras que la claudina 19 incrementa la selectividad catiónica de la claudina 16 bloqueando la permeabilidad aniónica. Recientemente se ha encontrado que la actividad promotora de la claudina 14 está localizada exclusivamente en la RAGH. Cuando se coexpresa con la claudina 16, la claudina 14 inhibe la permeabilidad de la claudina 16, reduciendo la permeabilidad paracelular al calcio. El proceso de reabsorción de calcio en la RGAH está estrechamente regulado por el receptor sensor de calcio (CaSR que monitorea los niveles circulantes de Ca ajustando la tasa de excreción renal de forma acorde. Dos micro-ARN, los mir-9 y mir-374, son regulados directamente por el CaSR. Los miR-9 y miR-374 suprimen la traslación del ARNm de la claudina 14 e inducen su decaimiento.

    Urothelial carcinoma (UC) originated from renal pelvis is the common tumor of the urinary system, however, neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in the complete renal and ureteral duplex cases. We present the first case of renal pelvis UC of the upper moiety in a complete right renal duplex. This male patient has bilateral complete renal and ureteral duplex. To the best of our knowledge, this is the first reported case of renal pelvis UC in a complete renal duplex system. After this experience we feel that the diagnosis of renal pelvis UC in duplex kidneys is not so easy, and once the diagnosis is determined, the whole renal duplex units and bladder cuff or ectopic orifice should be excised radically.

    2015-01-01

    The prevalence of both hypogonadism and renal failure is increasing. Hypogonadism in men with renal failure carries with it significant morbidity, including anemia and premature cardiovascular disease. It remains unclear whether testosterone therapy can affect the morbidity and mortality associated with renal failure. As such, in this review, we sought to evaluate the current literature addressing hypogonadism and testosterone replacement, specifically in men with renal failure. The articles chosen for this review were selected by performing a broad search using Pubmed, Embase and Scopus including the terms hypogonadism and renal failure from 1990 to the present. This review is based on both primary sources as well as review articles. Hypogonadism in renal failure has a multifactorial etiology, including co-morbid conditions such as diabetes, hypertension, old age and obesity. Renal failure can lead to decreased luteinizing hormone production and decreased prolactin clearance that could impair testosterone production. Given the increasing prevalence of hypogonadism and the potential morbidity associated with hypogonadism in men with renal failure, careful evaluation of serum testosterone would be valuable. Testosterone replacement therapy should be considered in men with symptomatic hypogonadism and renal failure, and may ameliorate some of the morbidity associated with renal failure. Patients with all stages of renal disease are at an increased risk of hypogonadism that could be associated with significant morbidity. Testosterone replacement therapy may reduce some of the morbidity of renal failure, although it carries risk.

    Dynamic renal scintigraphy has been reviewed for evaluation of renal arterial involvement in aortic disorders such as arteriosclerosis obliterans, abdominal aortic aneurysm and dissecting aneurysm. As a diagnostic finding and parameters, we used blood perfusion images of both kidneys and relative split renal function index obtained with analysis of the time-activity curves which were generated using a renal region of interest. In the diagnosis of unilateral renal arterial involvement, sensitivity and specificity of blood perfusion images were 100 % (9/9) and 77 % (10/13) and those of relative split renal function index were 78 % (7/9) and 92 % (12/13), respectively. Dynamic renal scintigraphy was useful for evaluating unilateral renal arterial involvement in aortic diseases. However, scintigraphic diagnosis of bilateral renal arterial involvement were difficult. And in a severe case, we could not differentiate renal parenchymal damage due to renovascular involvement from senile renal dysfunction or hypertensive renal disease which is often a cause of aortic disorders.

    Dopamine D2 receptor (DRD2) deficiency increases renal inflammation and blood pressure in mice. We show here that long-term renal-selective silencing of Drd2 using siRNA increases renal expression of proinflammatory and profibrotic factors and blood pressure in mice. To determine the effects of renal-selective rescue of Drd2 expression in mice, the renal expression of DRD2 was first silenced using siRNA and 14 days later rescued by retrograde renal infusion of adeno-associated virus (AAV) vector with DRD2. Renal Drd2 siRNA treatment decreased the renal expression of DRD2 protein by 55%, and DRD2 AAV treatment increased the renal expression of DRD2 protein by 7.5- to 10-fold. Renal-selective DRD2 rescue reduced the expression of proinflammatory factors and kidney injury, preserved renal function, and normalized systolic and diastolic blood pressure. These results demonstrate that the deleterious effects of renal-selective Drd2 silencing on renal function and blood pressure were rescued by renal-selective overexpression of DRD2. Moreover, the deleterious effects of 45-minute bilateral ischemia/reperfusion on renal function and blood pressure in mice were ameliorated by a renal-selective increase in DRD2 expression by the retrograde ureteral infusion of DRD2 AAV immediately after the induction of ischemia/reperfusion injury. Thus, 14 days after ischemia/reperfusion injury, the renal expression of profibrotic factors, serum creatinine, and blood pressure were lower in mice infused with DRD2 AAV than in those infused with control AAV. These results indicate an important role of renal DRD2 in limiting renal injury and preserving normal renal function and blood pressure. PMID:27358912

    Introduction: The recent success of renal denervation in lowering blood pressure in drug-resistant hypertensive patients has stimulated interest in developing novel approaches to renal denervation including local drug/chemical delivery. The purpose of this study was to develop a rat model in which depletion of renal norepinephrine (NE) could be used to determine the efficacy of renal denervation after the delivery of a chemical to the periadventitial space of the renal artery. Methods: Renal denervation was performed on a single renal artery of 90 rats (n = 6 rats/group). The first study determined the time course of renal denervation after surgical stripping of a renal artery plus the topical application of phenol in alcohol. The second study determined the efficacy of periadventitial delivery of hypertonic saline, guanethidine, and salicylic acid. The final study determined the dose–response relationship for paclitaxel. In all studies, renal NE content was determined by liquid chromatography–mass spectrometry. Results: Renal NE was depleted 3 and 7 days after surgical denervation. Renal NE was also depleted by periadventitial delivery of all agents tested (hypertonic saline, salicylic acid, guanethidine, and paclitaxel). A dose response was observed after the application of 150 μL of 10{sup −5} M through 10{sup −2} M paclitaxel. Conclusion: We developed a rat model in which depletion of renal NE was used to determine the efficacy of renal denervation after perivascular renal artery drug/chemical delivery. We validated this model by demonstrating the efficacy of the neurotoxic agents hypertonic saline, salicylic acid, and guanethidine and increasing doses of paclitaxel.

    Based on experience gained from more than 1600 patients with proved or suspected kidney diseases and on results on extended studies with dogs, sequential scintigraphy was performed after renal transplantation in dogs. After intravenous injection of 500 {mu}Ci. {sup 131}I-Hippuran scintiphotos were taken during the first minute with an exposure time of 15 sec each and thereafter with an exposure of 2 min up to at least 16 min.. Several examinations were evaluated digitally. 26 examinations were performed on 11 dogs with homotransplanted kidneys. Immediately after transplantation the renal function was almost normal arid the bladder was filled in due time. At the beginning of rejection the initial uptake of radioactive Hippuran was reduced. The intrarenal transport became delayed; probably the renal extraction rate decreased. Corresponding to the development of an oedema in the transplant the uptake area increased in size. In cases of thrombosis of the main artery there was no evidence of any uptake of radioactivity in the transplant. Similar results were obtained in 41 examinations on 15 persons. Patients with postoperative anuria due to acute tubular necrosis showed still some uptake of radioactivity contrary to those with thrombosis of the renal artery, where no uptake was found. In cases of rejection the most frequent signs were a reduced initial uptake and a delayed intrarenal transport of radioactive Hippuran. Infarction could be detected by a reduced uptake in distinct areas of the transplant. (author)

    Despite the abundance of antihypertensive drugs, resistant hypertension remains a major clinical problem. Recent technological advances render interventional management of resistant hypertension one of the hottest topics in the hypertension field. The aim of this review is to present the pathophysiologic background and the mechanisms mediating blood pressure reduction after renal sympathetic denervation, to analyze recent findings with this fascinating approach and to critically suggest future research directions. Catheter-based, ablation-induced renal sympathetic denervation was initially studied in 45 patients with resistant hypertension in a proof-of-concept study. Impressive blood pressure reductions of about 30/15  mmHg were achieved at 6 months, without serious complications. A second, controlled, randomized (but not blinded) study confirmed the results, verifying the efficacy and safety of the procedure. A recent report revealed the 2-year durability of blood pressure reduction. Data published so far indicate that ablation-induced renal denervation is a feasible, effective, and well tolerated interventional approach for the management of resistant hypertension. The groundbreaking studies of renal denervation in drug-resistant hypertension pave the way for further research in other disease conditions in which sympathetic overactivity seems to play a critical role. This initial wave of enthusiasm needs to be followed by rigorous investigation, for the proper identification of the potential and the limitations, indications, and contraindications of this approach.

    2009-06-01

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Relationship between live donor renal anatomic asymmetry and posttransplant recipient function has not been studied extensively. We analyzed 96 live kidney donors, who had anatomical asymmetry (>10% renal length and/or volume difference calculated from computerized tomography angiograms) and their matching recipients. Split function differences (SFD) were quantified with technetium-dimercaptosuccinic acid renography. Implantation biopsies at time 0 were semiquantitatively scored. A comprehensive model using donor renal volume adjusted to recipient weight (Vol/Wgt), SFD, and biopsy score was used to predict recipient estimated glomerular filtration rate (eGFR) at 1 year. Primary analysis consisted of a logistic regression model of outcome (odds of developing eGFR>60 mL/min/1.73 m(2) at 1 year), a linear regression model of outcome (predicting recipient eGFR at one-year, using the chronic kidney disease-epidemiology collaboration formula), and a Monte Carlo simulation based on the linear regression model (N=10,000 iterations). In the study cohort, the mean Vol/Wgt and eGFR at 1 year were 2.04 mL/kg and 60.4 mL/min/1.73 m(2), respectively. Volume and split ratios between 2 donor kidneys were strongly correlated (r = 0.79, P 10%) were not different (P = 0.190). On multivariate models, only Vol/Wgt was significantly associated with higher odds of having eGFR > 60 mL/min/1.73 m (odds ratio, 8.94, 95% CI 2.47-32.25, P = 0.001) and had a strong discriminatory power in predicting the risk of eGFR less than 60 mL/min/1.73 m(2) at 1 year [receiver operating curve (ROC curve), 0.78, 95% CI, 0.68-0.89]. In the presence of donor renal anatomic asymmetry, Vol/Wgt appears to be a major determinant of recipient renal function at 1 year after transplantation. Renography can be replaced with CT volume calculation in estimating split renal function.

    Percutaneous transluminal renal angioplasty with stenting has been effective in the control of hypertension, renal function, and pulmonary edema caused by atherosclerotic renal artery stenosis. However, the role of the procedure has not been fully established in the context of chronic total occlusion of renal artery. We report the successful use of this procedure in 57-year-old male patient who reported for evaluation of a recent episode of accelerated hypertension. A renal angiogram in this patient showed ostial stenosis of the right renal artery, which was filling by way of the collateral artery. Renal angioplasty for chronic total occlusion of right renal artery was successfully performed in a retrograde fashion through a collateral artery, thereby leading to improvement of renal function and blood pressure control.

    Objective: To discuss the clinical efficacy and complications of super selective renal arterial embolization in treating acute renal arterial bleeding in patients with renal insufficiency, and to evaluate the influence of the treatment on the renal function. Methods: During the period of January 2000 December 2009, super selective renal arterial embolization was performed in our institution for acute renal bleeding in 13 patients with renal insufficiency. The complete clinical and imaging materials of all patients were properly collected. The clinical effectiveness, the renal function, the extent of embolization and the complications were observed and the relationship between each other was analyzed. Results: The embolization procedure was successfully completed in all patients with a technical success rate of 100%. The mean embolized territory was 22% of a single kidney. Three days after the procedure, the hemoglobin level, hematocrit, blood pressure and heart rate were considerably improved in all patients. Compared to the corresponding preoperative data, all the differences were statistically significant (P 0.05), while the blood urea nitrogen was markedly decreased (P=0.011). Post embolization syndrome occurred in 5 patients and progressive aggravation of the renal function was observed in one patient, who had to receive hemodialysis finally. The embolized territory in patients occurring complications was larger than that in patients without occurring complications (U=1.500, P=0.006). Conclusion: Super selective renal arterial embolization is an effective and safe treatment for acute renal arterial bleeding in patients with renal insufficiency, the therapy will not significantly worsen the renal function. Appropriate and reasonable extent of embolization, as small as possible, is the key point for reducing the complications. (authors)

  19. Renal replacement therapy in sepsis-induced acute renal failure

    Directory of Open Access Journals (Sweden)

    Rajapakse Senaka

    2009-01-01

    Full Text Available Acute renal failure (ARF is a common complication of sepsis and carries a high mortality. Renal replacement therapy (RRT during the acute stage is the mainstay of therapy. Va-rious modalities of RRT are available. Continuous RRT using convective methods are preferred in sepsis-induced ARF, especially in hemodynamically unstable patients, although clear evidence of benefit over intermittent hemodialysis is still not available. Peritoneal dialysis is clearly inferior, and is not recommended. Early initiation of RRT is probably advantageous, although the optimal timing of dialysis is yet unknown. Higher doses of RRT are more likely to be beneficial. Use of bio-compatible membranes and bicarbonate buffer in the dialysate are preferred. Anticoagulation during dialysis must be carefully adjusted and monitored.

    Objective: To identify the causes of acute renal failure (ARF) in pediatric population along with the identification of the age and gender most affected by the failure. Subjects and Methods: The study included children under the age of 12 years who presented with signs and symptoms suggestive of ARF (oliguria/anuria, vomiting, acidotic breathing etc.) along with raised blood urea nitrogen (BUN) serum creatinine and metabolic acidosis as shown by arterial blood gases (ABGs). Patients were divided into two group on the basis of age; group A consisting of 0-2 years and group B from >2 years. Patients presenting with transient pre-renal azotaemia were excluded from the study. After providing initial emergency cover, detailed history, physical examination and investigations were carried out according to a proforma specially designed to ascertain the cause of ARF. Patients were managed for ARF as per standard recommendations and investigations completed or repeated as and when required. Results: A total of 119 patients with ARF were admitted in the ward over a period of two years constituting 1.36% of the total admissions and 16.39% of the admissions due to renal pathology. Mean age of presentation was 4.5 years 16.7% of the patients under the age of 5 years. Male predominance was noted in all ages with an overall male to female ratio of 2.3:1. Most common cause leading to ARF in younger age group was found to be hemolytic uremic syndrome [25(54.34%)] followed by septicemia [7(15.21 %)]. In older patients renal calculus disease was the most common [22(30.13%)] underlying pathology followed by pre-existing, undiagnosed chronic renal failure [16(21.91 %)]. Conclusion: ARF is fairly cotton in children especially under the age of 5 years showing a male predominance. More than 90% of the cases can be prevented by improving primary health care and by early and prompt treatment of infections. (author)

    To evaluate the efficacy and safety of ultrasound (US)-guided percutaneous microwave ablation (MWA) for renal cell carcinoma (RCC) adjacent to renal sinus. This retrospective study included 41 patients who underwent US-guided percutaneous MWA of 41 RCCs adjacent to the renal sinus from April 2006 to December 2015. Contrast-enhanced images of US and computed tomography (CT) or magnetic resonance (MR) imaging were performed at pre-ablation and 1day, 1 month, 3 months, and every 6 months after ablation. Initial ablation success (IAS), disease-free survival (DFS), RCC-related survival (RRS), and overall survival (OS) were recorded at the follow-up visits. IAS was achieved in 92.7% (38/41) of the study subjects. The IAS significantly differed between patients with RCCs ≤4cm (100%, 29/29) and RCCs >4cm (75%, 9/12, p=0.021). During the median follow-up of 37.6 (range, 3.0-97.3) months, the estimated 1-, 3-, and 5-year DFS of patients with an initial tumor of ≤4cm were 100%, 89.7%, and 81.5%, respectively. The 1-, 3-, and 5-year RRS were 100%, 93.3%, and 93.3%, respectively. The 1-, 3-, and 5-year OS were 97.1%, 87.8%, and 83.6%, respectively. The multivariate analysis using the Cox proportional hazard model revealed no independent predictor of recurrence among all the variables. There were no MWA-related deaths among the study subjects. One patient developed a retroperitoneal abscess after ablation. US-guided percutaneous MWA appears to be a promising method for RCCs adjacent to renal sinus, especially for tumors ≤4cm.

    PurposeRenal denervation (RDN) emerged as an innovative interventional antihypertensive therapy. With the exception of pretreatment blood pressure (BP) level, no other clear predictor for treatment efficacy is yet known. We analyzed whether the presence of multiple renal arteries has an impact on BP reduction after RDN.MethodsFifty-three patients with treatment-resistant hypertension (office BP ≥ 140/90 mmHg and 24-h ambulatory BP monitoring (≥130/80 mmHg) underwent bilateral catheter-based RDN. Patients were stratified into one-vessel (OV) (both sides) and at least multivessel (MV) supply at one side. Both groups were treated on one vessel at each side; in case of multiple arteries, only the dominant artery was treated on each side.ResultsBaseline clinical characteristics (including BP, age, and estimated glomerular filtration rate) did not differ between patients with OV (n = 32) and MV (n = 21). Office BP was significantly reduced in both groups at 3 months (systolic: OV −15 ± 23 vs. MV −16 ± 20 mmHg; diastolic: OV −10 ± 12 vs. MV −8 ± 11 mmHg, both p = NS) as well as 6 months (systolic: OV −18 ± 18 vs. MV −17 ± 22 mmHg; diastolic: OV −10 ± 10 vs. −10 ± 12 mmHg, both p = NS) after RDN. There was no difference in responder rate (rate of patients with office systolic BP reduction of at least 10 mmHg after 6 months) between the groups.ConclusionIn patients with multiple renal arteries, RDN of one renal artery—namely, the dominant one—is sufficient to induce BP reduction in treatment-resistant hypertension

Office BP was significantly reduced in both groups at 3 months (systolic: OV -15 {+-} 23 vs. MV -16 {+-} 20 mmHg; diastolic: OV -10 {+-} 12 vs. MV -8 {+-} 11 mmHg, both p = NS) as well as 6 months (systolic: OV -18 {+-} 18 vs. MV -17 {+-} 22 mmHg; diastolic: OV -10 {+-} 10 vs. -10 {+-} 12 mmHg, both p = NS) after RDN. There was no difference in responder rate (rate of patients with office systolic BP reduction of at least 10 mmHg after 6 months) between the groups.ConclusionIn patients with multiple renal arteries, RDN of one renal artery-namely, the dominant one-is sufficient to induce BP reduction in treatment-resistant hypertension.

    Orthotopic renal transplant (ORT) is useful in cases of severe atherosclerosis, heterotopic bilateral transplant, unsuitable pelvic vessels and in aortic thrombosis, but it is not available in all the institutions and it is only realized of exceptional form. To review the indication, surgical technique and outcome of the ORT at our hospital. The studied included five cases between January 1990 and December 2005. We analyzed several variables: demographic characteristics, characteristics of the donor, ischemia times, evolution of renal function and morbi-mortality associated. Left ORT was performed in three men and two women. Mean patient age was 52+/-5 years, all the patients received kidneys from cadaveric donors. Mean creatinine and urea one month postoperative were 2.2+/-0.72 mg/dl and 103+/-17.2 mg/dl and at 6 months postoperative were 1.8+/-0.59 mg/dl and 78+/-14 mg/dl respectively. Immediately all patients received prophylaxis with low molecular weight heparin but it was indicated antiaggregation to two patients when they left the hospital, anticoagulation to two patients and to one of them was decided to anticoagulation nor antiagregation for history of bled digestive. A patient died for bleeding episode at level of the renal graft six months after the transplant, she was in treatment with dicumarinics, they were indicated by venous deep thrombosis in right leg. The survival a year is 80 % of the graft and the patient. Only two patients returned to hospital later, one of them for presenting an episode of diverticulitis and the other one for renal obstructive failure that needed laying of catheter pig-tail. Four patients presented stenosis of renal native vassels detected in control magnetic nuclear resonance, not symptomatic. There are two patients who take more than three years transplanted with renal stable function (creatinina 1.3 mg/dl and 1.4 mg/dl respectively). ORT is an excellent option in patients with co-morbidity increased for atherosclerosis and

    Pre-clinical studies of renal denervation would suggest that the extent of renal nerve injury correlates with outcomes. The “completeness” of renal nerve injury following renal denervation correlates with treatment-based variables such as the depth of ablation, the number of ablations along the length of the artery, and the number of renal arteries successfully ablated. Renal denervation techniques targeting only main renal arteries may lead to suboptimal results in patients with accessory re...

    Hospitalizations due to heart failure are increasing steadily despite advances in medicine. Patients hospitalized for worsening heart failure have high mortality in hospital and within the months following discharge. Kidney dysfunction is associated with adverse outcomes in heart failure patients. Recent evidence suggests that both deterioration in kidney function and renal congestion are important prognostic factors in heart failure. Kidney congestion in heart failure results from low cardiac output (forward failure), tubuloglomerular feedback, increased intra-abdominal pressure or increased venous pressure. Regardless of the cause, renal congestion is associated with increased morbidity and mortality in heart failure. The impact on outcomes of renal decongestion strategies that do not compromise renal function should be explored in heart failure. These studies require novel diagnostic markers that identify early renal damage and renal congestion and allow monitoring of treatment responses in order to avoid severe worsening of renal function. In addition, there is an unmet need regarding evidence-based therapeutic management of renal congestion and worsening renal function. In the present review, we summarize the mechanisms, diagnosis, outcomes, prognostic markers and treatment options of renal congestion in heart failure.

    Full Text Available Objective: During partial nephrectomy, renal hypothermia has been shown to decrease ischemia induced renal damage which occurs from renal hilar clamping. In this study we investigate the infusion rate required to safely cool the entire renal unit in a porcine model using retrograde irrigation of iced saline via dual-lumen ureteral catheter. Materials and Methods: Renal cortical, renal medullary, bowel and rectal temperatures during retrograde cooling in a laparoscopic porcine model were monitored in six renal units. Iced normal saline was infused at 300 cc/hour, 600 cc/hour, 1000 cc/hour and gravity (800 cc/hour for 600 seconds with and without hilar clamping. Results: Retrograde cooling with hilar clamping provided rapid medullary renal cooling and significant hypothermia of the medulla and cortex at infusion rates ≥ 600 cc/hour. With hilar clamping, cortical temperatures decreased at -0.9° C/min. reaching a threshold temperature of 26.9° C, and medullary temperatures decreased at -0.90 C/min. reaching a temperature of 26.1° C over 600 seconds on average for combined data at infusion rates ≥ 600 cc/hour. The lowest renal temperatures were achieved with gravity infusion. Without renal hilum clamping, retrograde cooling was minimal at all infusion rates. Conclusions: Significant renal cooling by gravity infusion of iced cold saline via a duel lumen catheter with a clamped renal hilum was achieved in a porcine model. Continuous retrograde irrigation with iced saline via a two way ureteral catheter may be an effective method to induce renal hypothermia in patients undergoing robotic assisted and/or laparoscopic partial nephrectomy.

También hay una serie de fenómenos propiamente culturales, que son los que los denominados "estudios culturales" (G. Canclini. M. Barbero, etc. han asumido en Latinoamérica. Tales estudios han aportado una descripción de fenómenos nuevos, que no son analizados por ningún otro discurso teórico (tribus urbanas, identidades lábiles, influencia de los medios en los nuevos estilos de consumo, etc..

    Embolization was performed in six patients with renal artery aneurysms (n=2) and arteriovenous fistulas (AVF) (n=5). The aneurysms were observed in one patient with fibromuscular dysplasia and in another with Ehlers-Danlos syndrome. All the AVFs were intraparenchymal and secondary to iatrogenic trauma. Elective embolization was performed in five patients with good clinical results at follow-up between 1 and 9 years. Because of rupture of the aneurysm emergency embolization was attempted without success in the patient with Ehlers-Danlos syndrome, and nephrectomy was carried out. A postembolization syndrome complicated three procedures in which Gelfoam and polyvinyl alcohol were used; in two of these cases unexpected reflux of the particulate material occurred, resulting in limited undesired ablation of the ipsilateral renal parenchyma. Embolization is the most reliable and effective treatment for intrarenal vascular abnormalities since it minimizes the parenchymal damage. (orig.)

    25 patients with chronic renal disease are investigated. In 16 cases with conservative treatment the bone scintigram showed pathological uptake according to the creatinine level, mainly in the joints of iliosacrum, hip, knee and ankles. In three patients increased uptake in the skull was found. The bone uptake found by scintigraphy was highly pronounced in the patients treated by dialysis. The most frequently involved regions were the joints of iliocacrum and hip, facial cranium, skull, pelvis and metatarsus. The count-rate ratio of cranium to chest was significantly increased in 6 patients. The investigations 6 months later showed in 4 cases a further increase compared with the first values. Count-rates of the skull were found to be comparable to the highly increased uptake in Paget's disease. Bone scintigraphy is a suitable method to estimate semiquantitatively the bone turnover in renal disease. (orig.) [de

    The aim of the study was to estimate the clinical relevance and accuracy of dynamic renal scintigraphy (DRS) in case of obstructed kidneys as hydronephrosis is among the complications at different renal diseases, like nephrolithiasis and urolithiasis. Twenty-one patients mainly with unilateral hydronephrosis were studied. DRS with 99m Tc-MAG3 or 99m Tc-EC was done and quantitative parameters of the morphological and functional status of every kidney were assessed. At 24 % of the patients accumulation curves typical for obstructed by hydronephrosis kidneys were obtained. At 38 % the type of renograms of the affected kidneys was intermediate one, closer to that at the cases with nephrosclerosis, with lower uptake and severe parenchymal changes. The rest 38 % of the cases showed normal renograms or slightly delayed downslope. DRS is a very precise and sensitive method for evaluation of the degree of kidney damage in cases with hydronephrosis

    1987-01-01

    The US appearances in seven pathologically and/or surgically proved cases of renal allograft rupture are presented. These include a triangular or amorphous echogenic area in the cortex and medulla in a polar location, an echogenic band or wavy, branching anechoic lines in the hyperechoic region, a subcapsular hematoma, and an extrarenal hematoma in direct continuity with the echogenic area. Duplex Doppler examination in renal allograft rupture shows marked reduction of absence of the diastolic component of the velocity waveform in the arcuate and interlobar arteries, with reduction in amplitude of the systolic wave form. Correlation of the US appearances with gross and microscopic pathologic findings indicates that the echogenic area is due to an intrarenal hematoma, while the echogenic band represents the cortical laceration with adherent blood clots. The US-duplex Doppler examination should be the primary diagnostic modality in this life-threatening condition

    2001-01-01

    To evaluate the blood flow velocity waveform of the renal artery and renal volume of growth-retarded fetuses and to compare them with those of normal fetuses. Pulsatility index of the renal artery and renal volume measured by three-dimensional ultrasonography were obtained from seventy eight normal fetuses at the gestational age from twenty five to thirty nine weeks and eighteen intrauterine growth retarded fetuses whose weight was below ten percentile at birth. We studied changes of the pulsatility index of the renal artery and renal volume according to the gestational age and compared with those of growth-retarded fetuses. Pulsatility index (PI) of the fetal renal artery decreased throughout the gestational period (r=0.703, p<0.0001). In growth-retarded fetuses, despite of abnormal doppler velocity waveform of the middle cerebral artery, which was showing fetal hypoxia, the renal PI was not increased significantly. The fetal renal volume increased throughout the gestational period (r=0.834, p<0.0001) whereas in growth-retarded fetuses, all renal volume was below fifth percentile of normal fetuses. In growth-retarded fetuses, fetal renal volume was decreased significantly without change of the renal vascular flow. Therefore, the fetal renal volume measured by three-dimensional ultrasonography may be a helpful parameter in the diagnosis of growth-retarded fetuses.

    Type A or B aortic dissection can extend to renal arteries, causing a renal ischemia which treatment is usually endovascular. The aim of our study is to show the interest of the renal volumetry in the follow-up of these patients. Twenty-two patients (16 men, mean age 63.4±11.8years, BMI 25.2±3.4kg/m(2)) with a type A or B aortic dissection spread to one or to both renal arteries and followed at Grenoble university hospital were consecutively included. All patients underwent renal angiography with aorto-renal pressure gradients measurements and follow-up by renal volumetry (scanner Siemens(®)). A renal ischemia was defined by a decrease of 20% or more of the volumetry. Sixteen patients (73%) were hypertensive before the aortic dissection among which ten (62%) were treated. Eight patients (36%) have a significant renal pressure gradient among which five (62%) underwent renal endovascular therapy. The renal volumetry of these five patients remained unchanged while six of 17 patients (36%) without angioplasty have a decreasing volumetry. Renal volumetry appeared an effective and attractive option for the follow-up of the patients with aortic dissection spread to the renal arteries. These results should be taken into account to put the indication of an endovascular treatment. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    To evaluate the blood flow velocity waveform of the renal artery and renal volume of growth-retarded fetuses and to compare them with those of normal fetuses. Pulsatility index of the renal artery and renal volume measured by three-dimensional ultrasonography were obtained from seventy eight normal fetuses at the gestational age from twenty five to thirty nine weeks and eighteen intrauterine growth retarded fetuses whose weight was below ten percentile at birth. We studied changes of the pulsatility index of the renal artery and renal volume according to the gestational age and compared with those of growth-retarded fetuses. Pulsatility index (PI) of the fetal renal artery decreased throughout the gestational period (r=0.703, p<0.0001). In growth-retarded fetuses, despite of abnormal doppler velocity waveform of the middle cerebral artery, which was showing fetal hypoxia, the renal PI was not increased significantly. The fetal renal volume increased throughout the gestational period (r=0.834, p<0.0001) whereas in growth-retarded fetuses, all renal volume was below fifth percentile of normal fetuses. In growth-retarded fetuses, fetal renal volume was decreased significantly without change of the renal vascular flow. Therefore, the fetal renal volume measured by three-dimensional ultrasonography may be a helpful parameter in the diagnosis of growth-retarded fetuses.

    Full Text Available Leiomyomas are smooth muscle tumours that are rarely found in the kidney. There is one report of a leiomyoma in a kidney transplant in a paediatric recipient. Here, we report an adult renal transplant recipient who developed an Epstein-Barr virus-positive leiomyoma in his allograft 15 years after transplantation. The patient was converted to everolimus for posttransplant immunosuppression management and there was no sign of progression over a year.

    Full Text Available Congenital hypopituitarism is potentially fatal in the newborn period but treatable if the diagnosis is made early. We report a neonate who presented with hypothermia and severe hypoglycemia. He also had undescended testis and micropenis. Initial screening revealed panhypopituitarism, which was corrected promptly. He developed renal failure due to initial cardiovascular compromise related to hypotension but recovered quickly with standard management. Magnetic resonance imaging revealed absent stalk of anterior pituitary.

    Primary hyperparathyroidism (PHPT) is associated with nephrolithiasis and nephrocalcinosis. Hypercalciuria is one of the multiple factors that is implicated in the complex pathophysiology of stone formation. The presence of a renal stone (symptomatic or asymptomatic) categorizes PHPT as symptomatic and is an indication for parathyroid adenomectomy. Progression of nephrocalcinosis is largely reversible after successful surgery, but the residual risk persists. PHPT is also associated with decli...

    To evaluate the radiographic and CT findings of pulmonary complications other than pulmonary edema arising from renal transplantation. Among 393 patients who had undergone renal transplantation at our hospital during a previous ten-year period, 23 with pulmonary complications other than pulmonary edema were included in this study. The complications involved were infection caused by CMV (n=6), bacteria (n=4), fungus (n=4), tuberculosis (n=2), varicella (n=1) or chlamydia (n=1), and malignancy involving lung cancer (n=4) or Kaposi's sarcoma (n=1). Two chest radiologists reviewed all images. The complications manifesting mainly as pulmonary nodules were lung cancer (4/4), tuberculosis (1/2), and Kaposi's sarcoma (1/1). Pulmonary consolidation was a main feature in bacterial infection (4/4), fungal infection (3/4), tuberculosis (1/2), chlamydial infection (1/1), and varicellar pneumonia (1/1). Ground-glass attenuation was a main CT feature in CMV pneumonia (4/6), and increased interstitial making was a predominant radiographic feature in CMV pneumonia (2/6). The main radiologic features described above can be helpful for differential diagnosis of the pulmonary complications of renal transplantation.

    Renal transplantation with a well-functioning graft leads to a rapid restoration of endocrine and sexual functions. The aim of this study was to examine our experience with pregnancies among renal transplant patients, particularly with regard to their impact on graft function. We analyzed 10 pregnancies in 7 renal transplant recipients for long-term graft outcomes in terms of clinical and biological data. The mean patient age was 28.5 +/- 4 years. They all received a living donor kidney. The time between transplantation and the onset of pregnancy was 33.4 +/- 23.2 months. Regarding the immunosuppressive therapy, all patients received steroids and cyclosporine; 4 patients received in addition azathioprine and 2 received mycophenolate mofetil that was changed at 1 month before conception to azathioprine. There was no significant difference between the serum creatinine before and during pregnancy. We did not observe any acute rejection episode. Pregnancy complications were preclampsia in 1 case, hypertension in 1 case, urinary tract infection in 2 cases, and anemia in 80% of patients during the third trimester. Premature rupture of membranes occurred in 1 case and preterm delivery in 2 cases. Two cases of neonatal death were registered. Cesarean section was performed in 50% of cases. The follow-up revealed 2 cases of chronic rejection. A multidisciplinary approach is necessary for pregnancy which generally occurs at 2 years after kidney transplantation.

  13. Renal disease and mitochondrial genetics.

    Respiratory chain (RC) deficiencies have long been regarded as neuromuscular diseases mainly originating from mutations in the mitochondrial DNA. Oxidative phosphorylation, i.e. adenosine triphosphate (ATP) synthesis-coupled electron transfer from substrate to oxygen through the RC, does not occur only in the neuromuscular system. Therefore, a RC deficiency can theoretically give rise to any symptom, in any organ or tissue, at any age and with any mode of inheritance, owing to the dual genetic origin of RC enzymes (nuclear DNA and mitochondrial DNA). Mitochondrial diseases can give rise to various syndromes or association, namely, neurologic and neuromuscular diseases, cardiac, renal, hepatic, hematological and endocrin or dermatological presentations. The most frequent renal symptom is proximal tubular dysfunction with a more or less complete de Toni-Debre-Fanconi Syndrome. A few patients have been reported with tubular acidosis, Bartter Syndrome, chronic tubulointerstitial nephritis or nephrotic syndrome. The diagnosis of a RC deficiency is difficult when only renal symptoms are present, but should be easier when another, seemingly unrelated symptom is observed. Metabolic screening for abnormal oxidoreduction status in plasma, including lactate/pyruvate and ketone body molar ratios, can help to identify patients for further investigations. These include the measurement of oxygen consumption by mitochondria and the assessment of mitochondrial respiratory enzyme activities by spectrophotometric studies. Any mode of inheritance can be observed: sporadic, autosomal dominant or recessive, or maternal inheritance.

    Full Text Available At present, the diagnosis of renal allograft rejection requires a renal biopsy. Clinical management of renal transplant patients would be improved if rapid, noninvasive and reliable biomarkers of rejection were available. This study is designed to determine whether such protein biomarkers can be found in renal-graft tissue proteomic approach. Orthotopic kidney transplantations were performed using Fisher (F344 or Lewis rats as donors and Lewis rats as recipients. Hence, there were two groups of renal transplant models: one is allograft (from F344 to Lewis rats; another is syngrafts (from Lewis to Lewis rats serving as control. Renal tissues were collected 3, 7 and 14 days after transplantation. As many as 18 samples were analyzed by 2-D Electrophoresis and mass spectrometry (MALDI-TOF-TOF-MS. Eleven differentially expressed proteins were identified between groups. In conclusion, proteomic technology can detect renal tissue proteins associated with acute renal allograft rejection. Identification of these proteins as diagnostic markers for rejection in patients′ urine or sera may be useful and non-invasive, and these proteins might serve as novel therapeutic targets that also help to improve the understanding of mechanism of renal rejection.

    Renal Artery Stenosis (RAS), is one of the causes of secondary hypertension; there are many causes of renal artery stenosis, as atherosclerosis of the renal artery which account for 90% of cases of RAS; fibromuscular dysplasia accounts for 10% of RAS. Various causes of thrombophilia either due congenital causes or acquired causes and can lead to RAS. Our patient was presented by acute attack of epistaxis and hypertension. Angiography of the Renal Arteries,are showed no sign of renal artery stenosis. However, the right kidney showed upper pole infarction, and the left kidney showed evidence of functional lower pole renal artery stenosis, although there is no anatomical stenosis detected in angiography. Work up for the cause of thrombophilia did not help in the diagnosis, which may be due to an undiscovered cause of thrombophilia

    The interaction between acute heart failure (AHF) and renal dysfunction is complex. Several studies have evaluated the prognostic value of this syndrome. The aim of this systematic review, which includes non-selected samples, was to investigate the impact of different renal function variables on the AHF prognosis. The categories included in the studies reviewed included: creatinine, blood urea nitrogen (BUN), the BUN/creatinine quotient, chronic kidney disease, the formula to estimate the glomerular filtration rate, criteria of acute renal injury and new biomarkers of renal damage such as neutrophil gelatinase-associated lipocalin (NGAL and cystatin c). The basal alterations of the renal function, as well as the acute alterations, transient or not, are related to a worse prognosis in AHF, it is therefore necessary to always have baseline, acute and evolutive renal function parameters.

    Infection is the most common disease of the urinary tract in children, and various imaging techniques have been used to verify its presence and location. On retrospective analysis, 50 consecutive children with documented upper urinary tract infection had abnormal findings on renal cortical scintigraphy with 99mTc-glucoheptonate. The infection involved the renal poles only in 38 and the poles plus other renal cortical areas in eight. Four had abnormalities that spared the poles. Renal sonograms were abnormal in 32 of 50 children. Excretory urograms were abnormal in six of 23 children in whom they were obtained. Vesicoureteral reflux was found in 34 of 40 children in whom voiding cystourethrography was performed. These data show the high sensitivity of renal cortical scintigraphy with 99mTc-glucoheptonate in documenting upper urinary tract infection. The location of the abnormalities detected suggests that renal infections spread via an ascending mode and implies that intrarenal reflux is a major contributing factor

    A patient who was operated for an abdominal aortic aneurysm 7 years earlier presented with recently discovered iliac and renal artery aneurysms. The renal artery had an angulation of 90 o , but the aneurysm was successfully excluded using a covered vascular stent graft placed over an extrastiff guidewire. Even in cases of complex anatomy of a renal aneurysm, endovascular treatment should be considered. With development of more flexible and low-profile endoprosthesis with accurate deployment, these have become more usable

  8. Purinergic Signalling in Inflammatory Renal Disease

    Directory of Open Access Journals (Sweden)

    Nishkantha eArulkumaran

    2013-07-01

    Full Text Available Extracellular purines have a role in renal physiology and adaption to inflammation. However, inflammatory renal disease may be mediated by extracellular purines, resulting in renal injury. The role of purinergic signalling is dependent on the concentrations of extracellular purines. Low basal levels of purines are important in normal homeostasis and growth. Concentrations of extracellular purines are significantly elevated during inflammation and mediate either an adaptive role or propagate local inflammation. Adenosine signalling mediates alterations in regional renal blood flow by regulation of the renal microcirculation, tubulo-glomerular feedback, and tubular transport of sodium and water. Increased extracellular ATP and renal P2 receptor-mediated inflammation are associated with various renal diseases, including hypertension, diabetic nephropathy, and glomerulonephritis. Experimental data suggests P2 receptor deficiency or receptor antagonism is associated with amelioration of antibody-mediated nephritis, suggesting a pathogenic (rather than adaptive role of purinergic signalling. We discuss the role of extracellular nucleotides in adaptation to ischaemic renal injury and in the pathogenesis of inflammatory renal disease.

    Matthews, H.K.; Toal, R.L.

    1996-01-01

    Radiography has a limited role in the evaluation of the kidneys in foals and adult horses. Ultrasonography is the current method of choice for structural evaluation of the kidneys in horses as it provides additional information to standard serum chemistry and urinalysis evaluation. A variety of structural abnormalities have been identified in diseased equine kidneys with the use of ultrasound. Ultrasound guided renal biopsy is the preferred method for performing renal biopsy in the horse. The use of Duplex Doppler ultrasound may allow for the characterization of regional hemodynamics of the equine kidney, but is currently an untapped method for evaluation of equine renal hemodynamics. Radionuclide methods including scintigraphy and quantitative renal function measurement can be used to provide further information about equine renal function. Scintigraphy can provide structural and possibly functional information. Quantitative methods using radiopharmaceuticals can provide precise measurement of glomerular filtration rate and effective renal blood flow. This method is especially helpful in identifying acute renal failure and in guiding response to treatment. All equine renal imaging techniques should be a supplement to the physical examination and standard laboratory tests. Additional diagnostic aids such as urinary tract endoscopy should also be considered in horses with hematuria, hydroureter, and suspected calculi. Taken together, all these modalities provide a thorough evaluation of the equine renal system and provide a basis for the clinician to select treatment options and provide prognostic information to the owner

    The rationale behind catheter-based renal denervation is that afferent and efferent renal nerves play a role in the pathogenesis and maintenance of high blood pressure, and that this can be prevented by blocking the function of the renal nerves. Since the introduction of catheter-based renal denervation, several observational and a small number of randomised controlled trials have been conducted. The available evidence does not allow for a definitive conclusion regarding its efficacy. There have been no serious side-effects reported. The development of this treatment concept has not been finalised; new trials have just commenced or will start in the near future.

    Perirenal hematoma after a renal biopsy is a common complication that usually resolves spontaneously, but this rarely requires transfusions or surgical/radiological intervention. We report here on a case of a renal perforating artery that was mistaken for renal arterial bleeding in a 53-year-old woman who was complicated with perirenal hematoma after undergoing a percutaneous renal biopsy. On the color and pulsed wave Doppler ultrasonography, linear blood flow was seen in the perirenal hematoma, which extended perpendicularly from the renal parenchyma into the perirenal space, and this linear blood flow exhibited an arterial pulse wave. On CT angiography, the renal perforating artery was demonstrated as a curvilinear vessel coursing tangentially to the renal margin and we decided that it was a pseudolesion caused by the renal perforating artery. A renal perforating artery may be mistaken for renal arterial bleeding after a percutaneous renal biopsy. A renal perforating artery and arterial bleeding can be differentiated by the location and shape seen on a color Doppler examination and the pulse waves characteristics

On CT angiography, the renal perforating artery was demonstrated as a curvilinear vessel coursing tangentially to the renal margin and we decided that it was a pseudolesion caused by the renal perforating artery. A renal perforating artery may be mistaken for renal arterial bleeding after a percutaneous renal biopsy. A renal perforating artery and arterial bleeding can be differentiated by the location and shape seen on a color Doppler examination and the pulse waves characteristics

    Selective infusion of the epinephrine into the renal artery has been used in the field of the diagnostic and the therapeutic radiology for correct diagnosis and effective treatment, respectively. However, administration of overdose of epinephrine may cause serious complication, renal infarction. The study was undertaken to evaluate the sequential change of renal arterial constrictive effect of selective infusion of epinephrine into renal artery and to determine the critical doses of epinephrine producing irreversible renal infarct. A total of 25 rabbits are used, which are divided into 5 groups. Under the general anesthesia is made the selective infusion of various doses of epinephrine into the right renal artery of the rabbits. At the various time interval during and after the epinephrine infusion, renal angiography was done, and 24 hrs. later, gross and microscopic findings of the kidney were observed. The results are as follows; 1. Vasoconstriction of renal artery occurred within 2 mins. infusion, and maximum effect within 5 mins. 2. It seems that there is correlation between the amount of infused epinephrine and the time taken to recover from constriction of renal artery. 3. When epinephrine is infused into the renal artery in the rate of 1 ug/min., renal infarct is not noticed below the level of 10 mins., but correlation between the amount of infused epinephrine and the frequency of renal infarct occurs above 20 mins. infusion

    This study sought to assess the efficacy of catheter-based renal sympathetic denervation in patients with accessory renal arteries and to compare the blood pressure (BP)-lowering effect with that observed in patients with bilateral single renal arteries after renal denervation. Catheter-based renal sympathetic denervation causes significant BP reductions in patients with resistant hypertension. Seventy-four patients were included in this study. Patients were assigned to 2 main groups: a bilateral single renal arteries group I (n = 54) and an accessory renal arteries group II (n = 20). Group II consisted of 9 patients whose accessory renal arteries were all denervated (group IIa), and 11 patients whose accessory renal arteries were not, or only incompletely, denervated (group IIb). The primary endpoint was the change in office systolic BP after 6 months. The procedure was successful in all patients. Group I: mean BP at baseline was 166.2/89.4 ± 20.5/14.6 mm Hg and decreased by -16.6 (p renal denervation in patients with accessory renal arteries is less pronounced than in patients with bilateral single renal arteries.

    PurposeTo describe the incidence of multiple renal artery pseudoaneurysms (PSA) in patients referred for renal artery embolization following partial nephrectomy and to study its relationship to RENAL nephrometry scores.Materials and MethodsThe medical records of 25 patients referred for renal artery embolization after partial nephrectomy were retrospectively reviewed for the following parameters: size and number of tumors, RENAL nephrometry scores, angiographic abnormalities, technical and clinical outcomes, and estimated glomerular filtration rates (eGFRs) after embolization.ResultsTwenty-four patients had primary renal tumors, while 1 patient had a pancreatic tumor invading the kidney. Multiple tumors were resected in 4 patients. Most patients (92 %) were symptomatic, presenting with gross hematuria, flank pain, or both. Angiography revealed PSA with (n = 5) or without (n = 20) AV fistulae. Sixteen patients (64 %) had multiple PSA involving multiple renal vessels. Higher RENAL nephrometry scores were associated with an increasing likelihood of multiple PSA. Multiple vessels were embolized in 14 patients (56 %). Clinical success was achieved after one (n = 22) or two (n = 3) embolization sessions in all patients. Post-embolization eGFR values at different time points after embolization were not significantly different from the post-operative eGFR.ConclusionA majority of patients requiring renal artery embolization following partial nephrectomy have multiple pseudoaneurysms, often requiring selective embolization of multiple vessels. Higher RENAL nephrometry score is associated with an increasing likelihood of multiple pseudoaneurysms. We found transarterial embolization to be a safe and effective treatment option with no long-term adverse effect on renal function in all but one patient with a solitary kidney.

Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos  de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio. Anorexia Nervosa is an Eating Disorder defined (etimoligacally as a "nervouse loss of apetite". It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

    Full Text Available Diez pacientes afectados por diversas patologías que requerían tratamiento crónico con Vincristina, fueron sometidos a estudios electrofisiológicos en los que se valoró: el número de unidades motoras (UM funcionantes en los músculos de la eminencia tenar, los valores de los incrementos medios de UM, velocidad de conducción motora y su latencia residual en el nervio mediano, la velocidad de conducción sensitiva del mismo nervio y el estado de la transmisión neuromuscular. Los valores obtenidos fueron comparados con grupos controles. Los resultados mostraron disminución del número de UM; las UM remanentes presentaron amplitud reducida junto a otras cuyo tamaño no superaba el del grupo control, hecho que sugiere la incapacidad de lograr una reinervación adecuada. Las velocidades de conducción motora y sensitiva mostraron valores diminuídos, con mayor compromiso en los segmentos distales. Junto a estos datos se halló respuesta miasteniforme al estímulo repetitivo. Todos estos resultados permiten postular la existencia de un compromiso de la unidad motora, abarcando todos sus segmentos, en pacientes intoxicados con Vincristina.

    Acoustic radiation force impulse is a noninvasive method for evaluating tissue elasticity on ultrasound. Renal shear wave velocity measured by this technique has not been fully investigated in patients with renal disease. The aim of the present study was to compare renal shear wave velocity in end-stage renal disease patients and that in patients without chronic kidney disease and to investigate influencing factors. Renal shear wave velocities were measured in 59 healthy young subjects (control group), 31 subjects without chronic kidney disease (non-CKD group), and 39 end-stage renal disease patients (ESRD group). Each measurement was performed 10 times at both kidneys, and the mean value of eight of 10 measurements, excluding the maximum and minimum values, was compared. Renal shear wave velocity could be measured in all subjects. Renal shear wave velocity in the control group was higher than in the non-CKD group and in the ESRD group, and no difference was found between the non-CKD group and the ESRD group. Age and depth were negatively correlated to the renal shear wave velocity. In multiple regression analysis, age and depth were independent factors for renal shear wave velocity, while renal impairment was not. There was no difference between the non-CKD group and the ESRD group, even when ages were matched and depth was adjusted. Renal shear wave velocity was not associated with advanced renal impairment. However, it reflected alteration of renal aging, and this technique may be useful to detect renal impairment in the earlier stages. © 2015 Asian Pacific Society of Nephrology.

    At present, the diagnosis of renal allograft rejection requires a renalbiopsy. Clinical management of renal transplant patients would be improved ifrapid, noninvasive and reliable biomarkers of rejection were available. Thisstudy is designed to determine whether such protein biomarkers can be foundin renal graft tissue proteomic approach. Orthotopic kidney transplantationswere performed using Fisher (F344) or Lewis rats as donors and Lewis rats asrecipients. Hence, there were two groups of renal transplant models: one isallograft (from F344 to Lewis rats); another is syngrafts (from Lewis toLewis rats) serving as control. Renal tissues were collected 3, 7 and 14 daysafter transplantation. As many 18 samples were analyzed by 2-DElectrophoresis and mass spectrometry (MALDI-TOF-TOF-MS). Elevendifferentially expressed proteins were identified between groups. Inconclusion, proteomic technology can detect renal tissue proteins associatedwith acute renal allograft rejection. Identification of these proteins asdiagnostic markers for rejection in patient's urine or sera may be useful andnon-invasive, and these proteins might serve as novel therapeutic targetsthat also help to improve the understanding of mechanisms of renal rejection.(author)

    Full Text Available INTRODUÇÃO E OBJETIVOS: A primeira referência de retardo no esvaziamento gástrico (EG foi feita por Grodstein em 1979. Outros estudos foram publicados posteriormente, nem sempre confirmando essa observação. A importância do EG em anestesia pode ser resumida em um de seus aspectos principais, o jejum pré-operatório. O retardo no esvaziamento pode causar estase e aumentar o risco de vômito e aspiração pulmonar. A possibilidade de existir retardo do esvaziamento em urêmicos é atraente. Queixas dispépticas são comuns nesses pacientes e poderiam ser explicadas pela dificuldade de esvaziamento gástrico. Apesar das evidências, a literatura é muito controversa nesse aspecto. Não há consenso quanto aos resultados obtidos. Diferenças no método de estudo utilizado poderiam explicar esses resultados, observados em estudos clínicos e experimentais. O objetivo desse estudo foi rever alguns aspectos importantes da síndrome dispéptica em pacientes com insuficiência renal crônica (IRC terminal, com ênfase no retardo do EG. CONTEÚDO: Serão abordados os aspectos básicos relacionados com a fisiologia do EG, os métodos mais empregados para o estudo do EG, a síndrome dispéptica e a uremia e o esvaziamento gástrico na insuficiência renal crônica. CONCLUSÕES: O EG é um processo fisiológico complexo de transferência do alimento do estômago para o duodeno, cujos mecanismos ainda não estão devidamente esclarecidos. A cintilografia, utilizando refeições acrescidas de radiofármacos, é o exame mais utilizado para o estudo do EG. Uma porcentagem expressiva de pacientes com IRC terminal apresenta retardo no EG. Possivelmente outros mecanismos, além da uremia que participa da função motora gástrica, estão envolvidos nesta disfunção.INTRODUCCIÓN Y OBJETIVOS: La primera referencia de retardo en el vaciamiento gástrico (EG fue hecha por Grodstein en 1979.

    VACTERL association refers to a combination of congenital anomalies that can include: vertebral anomalies, anal atresia, cardiac malformations, tracheo-esophageal fistula with esophageal atresia, renal anomalies (typically structural renal anomalies), and limb anomalies. We conducted a description of a case series to characterize renal findings in a cohort of patients with VACTERL association. Out of the overall cohort, 48 patients (with at least three component features of VACTERL and who had abdominal ultrasound performed) met criteria for analysis. Four other patients were additionally analyzed separately, with the hypothesis that subtle renal system anomalies may occur in patients who would not otherwise meet criteria for VACTERL association. Thirty-three (69%) of the 48 patients had a clinical manifestation affecting the renal system. The most common renal manifestation (RM) was vesicoureteral reflux (VUR) in addition to a structural defect (present in 27%), followed by unilateral renal agenesis (24%), and then dysplastic/multicystic kidneys or duplicated collected system (18% for each). Twenty-two (88%) of the 25 patients with a structural RM had an associated anorectal malformation. Individuals with either isolated lower anatomic anomalies, or both upper and lower anatomic anomalies were not statistically more likely to have a structural renal defect than those with isolated upper anatomic anomalies (p = 0.22, p = 0.284, respectively). Given the high prevalence of isolated VUR in our cohort, we recommend a screening VCUG or other imaging modality be obtained to evaluate for VUR if initial renal ultrasound shows evidence of obstruction or renal scarring, as well as ongoing evaluation of renal health. © 2014 Wiley Periodicals, Inc.

MÉTODOS: É relatada a experiência do Serviço de Cirurgia Torácica do Hospital Universitário de Londrina de janeiro de 1998 a dezembro de 2004. Trata-se de um estudo retrospectivo, em que foram analisados 46 pacientes pneumonectomizados, divididos em dois grupos: drenados e não drenados. As doenças foram as mesmas: neoplasia, bronquiectasia e tuberculose. RESULTADOS: Foram drenados 21 pacientes e 25 não o foram. A complicação pós-operatória mais comum foi o enfisema subcutâneo (12 casos, sendo o tempo de internação menor (6,5 dias nos pacientes não drenados em relação aos drenados (10,2 dias, sem que tenham sido observadas complicações graves. CONCLUSÃO: A evolução favorável dos 25 pacientes não drenados e o tempo de internação menor levam ao questionamento da necessidade de drenagem rotineira da cavidade pleural pós-pneumonectomia.OBJECTIVE: To evaluate the need for post-pneumonectomy thoracic drainage. METHODS: This was a retrospective study of 46 patients having undergone pneumonectomy in the Thoracic Surgery Department of the Londrina University Hospital between January of 1998 and December of 2004. Patients were divided into two groups: those having been submitted to drainage and those not having been. The diseases involved were lung cancer, bronchiectasis and tuberculosis. RESULTS: Drainage was used in 21 patients, whereas no drainage was used in 25. The most common postoperative complication was subcutaneous emphysema (12 cases. Hospital stays were of shorter duration among patients who were not submitted to drainage than among those who were (mean, 6.5 days vs. 10.2 days. No serious postoperative complications were observed in the group of patients not submitted to drainage. CONCLUSION: The findings that evolutions were more favorable and hospital stays were shorter for the patients not submitted to drainage call into

    Full Text Available RESUMO: O presente trabalho descreve um estudo retrospectivo da casuística de Curicacas (Theristicus caudatus atendidas pelo Projeto de Atendimento Médico Veterinário a Animais Selvagens do Planalto Catarinense (CAV/UDESC nos anos de 2003-2014. Neste período foram atendidas 77 curicacas, todas de vida livre e do Planalto Catarinense. Constatou-se que 33.7% eram jovens, 16,8% adultas e 49,5% com idade indeterminada. Dessas, 22.1% eram machos, 14.3% fêmeas e os demais indefinidos. Em relação às afecções clínicas, 55.8% possuíam fr,tura óssea, 9,1% sinais neurológicos, 3,9% múltiplas lacerações na pele e músculos, 3,9% luxação em membro, 3,% hemorragia em cavidade oral, 2,6% ruptura de sacos aéreos, 2,6% dispneia, 2,6% diarreia e 1,3% peritonite. Em 20,8% dos casos apresentavam apenas sinais inespecíficos como desnutrição. Dos animais atendidos, 55,8% morreram; 28,6% foram eutanasiados; 5,2% tratados e encaminhados à sede do IBAMA ou CETAS; 2,6% realizou-se soltura e em 7,8% o destino não foi informado. Efetuou-se necropsia em 70,8%, sendo que em 82,6% dessas obteve-se o diagnóstico definitivo de traumatismo e em 2,2% o diagnóstico foi de peritonite secundária a perfuração de moela por corpo estranho metálico e 2,2% vieram a óbito por pneumonia causada por corpo estranho (projétil. A alta mortalidade das aves atendidas parece estar relacionada com a gravidade das lesões apresentadas e afecções secundárias aos traumatismos. A curicaca foi a espécie que apresentou o maior número de atendimentos pelo projeto durante o período descrito no estudo, demonstrando que o estudo da casuística dessa ave pode servir como indicador do risco a que outras espécies de aves da região estão sujeitas.

    Full Text Available O ácido hipúrico é o principal metabólito do tolueno, solvente amplamente utilizado em processos industriais e com importantes efeitos tóxicos, fato que justifica a preocupação em monitorar regularmente sujeitos com risco de exposição ocupacional a este solvente. O objetivo deste trabalho foi avaliar os níveis de ácido hipúrico encontrados em trabalhadores submetidos à monitorização biológica. Foi realizado um estudo retrospectivo com dados dos anos de 2002 a 2005, no qual foram analisados os resultados e a situação do empregado na oportunidade do exame (periódico, demissional e admissional. Os resultados indicam uma redução significativa nos níveis de ácido hipúrico em 2005. Exames periódicos obtiveram resultados superiores aos exames admissionais e demissionais, e não foi verificada diferença significativa nas proporções dos sujeitos agrupados de acordo com a situação funcional em cada um dos intervalos estabelecidos segundo o valor de referência e o índice biológico máximo permitido. Os níveis de ácido hipúrico detectados indicam um baixo de risco de exposição ao tolueno na população avaliada, provavelmente em decorrência da preocupação crescente com a implantação de medidas de higiene ocupacional.Hippuric acid is the primary metabolite of toluene, a solvent widely used in industrial processes with considerable toxic effects, a fact which justifies regularly monitoring individuals with occupational exposure to this solvent. This work aims at evaluating urinary hippuric acid levels found in workers subject to biological monitoring. A retrospective study was carried out with data referring from 2002 to 2005, in which exams results and employment status were analyzed (periodic, post-employment, and pre-employment exams. Results indicate a significant reduction in hippuric acid levels for 2005. Periodic exams presented higher results than pre-employment and post-employment exams. No significant

    To evaluate the clinical application of computed tomography-based measurement of renal cortical volume and split renal volume as a single tool to assess the anatomy and renal function in patients with renal tumors before and after partial nephrectomy, and to compare the findings with technetium-99m dimercaptosuccinic acid renal scan. The data of 51 patients with a unilateral renal tumor managed by partial nephrectomy were retrospectively analyzed. The renal cortical volume of tumor-bearing and contralateral kidneys was measured using ImageJ software. Split estimated glomerular filtration rate and split renal volume calculated using this renal cortical volume were compared with the split renal function measured with technetium-99m dimercaptosuccinic acid renal scan. A strong correlation between split renal function and split renal volume of the tumor-bearing kidney was observed before and after surgery (r = 0.89, P volumetry had a strong correlation with the split renal function measured using technetium-99m dimercaptosuccinic acid renal scan. Computed tomography-based split renal volume measurement before and after partial nephrectomy can be used as a single modality for anatomical and functional assessment of the tumor-bearing kidney. © 2017 The Japanese Urological Association.

    Full Text Available OBJECTIVE: We present our experience in a series of 17 consecutive pediatric patients submitted to retroperitoneal laparoscopic renal biopsy. MATERIALS AND METHODS: Retroperitoneal laparoscopic renal biopsy (LRB was performed in 5 boys and 12 girls. Mean age was 8.1 years and age range from 2 to 12. Two or three trocars were used to expose the inferior pole of the kidney, remove enough cortical parenchymal specimen and fulgurate the biopsy site. Assessment included surgical time, estimated blood loss, hospitalization period, analgesia requirements, complications and number of glomeruli present in the specimen. RESULTS: LRB was successfully performed in all 15 patients (88%. In two cases, LRB was not possible to be performed. One patient was converted to a transperitoneal laparoscopy due to tear in the peritoneum. The other patient had had previous abdominal surgery and, during retroperitoneal balloon dilation, the peritoneum was opened and the open biopsy was performed. A third patient had postoperatively a perirenal hematoma, which was solved spontaneously. Complication rate was 17.6% (3/17 cases. Mean operative time was 65 minutes, while mean estimated blood loss was 52 mL, mean hospital stay was 2.2 days and mean analgesic requirement was 100 mg of tramadol. The mean number of glomeruli present in the specimen was 60. CONCLUSION: Retroperitoneal laparoscopic renal biopsy in children is a simple, safe. Bleeding is still the most common complication. However, direct vision usually allows a safe control of this drawback. In our institution, laparoscopic approach is the chosen procedure in pediatric patients older than one - year - old.

    Initial studies of catheter-based renal arterial sympathetic denervation to lower blood pressure in resistant hypertensive patients renewed interest in the sympathetic nervous system's role in the pathogenesis of hypertension. However, the SYMPLICITY HTN-3 study failed to meet its prespecified blood pressure lowering efficacy endpoint. To date, only a limited number of studies have described the microanatomy of renal nerves, of which, only two involve humans. Renal arteries were harvested from 15 cadavers from the Klinikum Osnabruck and Schuchtermann Klinik, Bad Rothenfelde. Each artery was divided longitudinally in equal thirds (proximal, middle, and distal), with each section then divided into equal superior, inferior, anterior, and posterior quadrants, which were then stained. Segments containing no renal nerves were given a score value = 0, 1-2 nerves with diameter 4 nerves or nerve diameter ≥600 µm a score = 3. A total of 22 renal arteries (9 right-sided, 13 left-sided) were suitable for examination. Overall, 691 sections of 5 mm thickness were prepared. Right renal arteries had significantly higher mean innervation grade (1.56 ± 0.85) compared to left renal arteries (1.09 ± 0.87) (P renal artery has significantly higher innervation scores than the left. The anterior and superior quadrants of the renal arteries scored higher in innervation than the posterior and inferior quadrants did. The distal third of the renal arteries are more innervated than the more proximal segments. These findings warrant further evaluation of the spatial innervation patterns of the renal artery in order to understand how it may enhance catheter-based renal arterial denervation procedural strategy and outcomes. The SYMPLICITY HTN-3 study dealt a blow to the idea of the catheter-based renal arterial sympathetic denervation. We investigated the location and patterns of periarterial renal nerves in cadaveric human renal arteries. To quantify the density of the

    The renal and intrarenal haemodynamic pattern in 17 patients with essential hypertension of different severity and duration was studied by means of the 133-Xenon washout technique and the selective renal angiography. The mean and the cortical renal blood flows were on average significantly decreased as compared to the controls. A good agreement was found between the reduction in renal perfusion and the degree of vascular abnormalities as shown by angiography; on the contrary no correlation was found between the impairment in renal blood flow and the degree and/or duration of hypertension

    To investigate the renal pathological implications in type 2 diabetes mellitus patients with renal involvement. A total of 328 type 2 diabetes mellitus (T2DM) patients with renal involvement who underwent a renal biopsy and received follow-up for at least one year were recruited in our study. The patients were divided into the diabetic nephropathy (DN), non-diabetic renal disease (NDRD), and NDRD superimposed on DN groups based on the pathological diagnosis. Renal outcomes were defined by the initiation of renal replacement therapy or doubling of the serum creatinine. Kaplan-Meier analysis was used to compare renal survival, and Cox proportional hazard analysis was used to determine the predictors of renal outcomes in the DN group. Renal biopsy findings revealed that 188 patients (57.32%) had pure DN, 121 patients (36.89%) had NDRD alone, and 19 patients (5.79%) had NDRD superimposed on DN. The most frequent subclassification of NDRD was membranous nephropathy (MN). Compared with the NDRD and NDRD superimposed on DN groups, patients with pure DN had poorer renal function and lower renal survival rates. In the DN group, the five-year renal survival rates of glomerular classes of I, IIa, IIb, III and IV were 100%, 84.62%, 60%, 47.5% and 33.33%, respectively. Multivariate Cox proportional hazard analysis showed that the glomerular lesions, proteinuria and serum creatinine were independent risk factors for renal outcomes, while interstitial fibrosis/inflammation and arteriolar hyalinosis were not independently associated with renal outcomes in the DN group. Making an accurate pathologic diagnosis by renal biopsy is crucial for diabetes mellitus (DM) patients with renal involvement. The findings of our present study indicated that patients with pure DN had poorer renal outcomes than patients with NDRD or NDRD superimposed on DN. The classification of glomerular lesions, proteinuria and serum creatinine were independent risk factors for renal outcomes in the DN group

    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with renal transplantation with renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

    The authors present the renal tolerance for nonionic low-osmotic contrast agent iopromide (ultravist) on the ground of literature and of angiographic examinations in 10 patients with chronic renal failure. One patient only had significant temporary deterioration of renal function. The presented results showed that analyzed agent is less nephrotoxic than high osmolality contrast agents. The use of iopromide is strongly recommended in patients with chronic renal failure. The risk of depression of renal function after administration of contrast material is minimized. (author)

    Skull X-ray of 60 patients with chronic renal failure were examined. Alterations included diminished or increased bone density, radiolucent areas, pepper pot skull and the disappearance of vascular grooves and sutures. It is suggested that the radiological aspect of the skull is of very little diagnostic use in the assessment of uremic osteopathy since specific alterations are rare and tardive and show no correlation with clinical and laboratory findings. Skull X-ray can be usefull in assessing the effects of treatment (vitamin D derivaties, parathyroidectomy) and for the identification of focal lesions (brown tumors)

    Chronic kidney diseases generally lead to renal fibrosis. Despite great progress having been made in identifying molecular mediators of fibrosis, the mechanism that governs renal fibrosis remains unclear, and so far no effective therapeutic antifibrosis strategy is available. Here we demonstrated that a switch of metabolism from oxidative phosphorylation to aerobic glycolysis (Warburg effect) in renal fibroblasts was the primary feature of fibroblast activation during renal fibrosis and that suppressing renal fibroblast aerobic glycolysis could significantly reduce renal fibrosis. Both gene and protein assay showed that the expression of glycolysis enzymes was upregulated in mouse kidneys with unilateral ureter obstruction (UUO) surgery or in transforming growth factor-β1 (TGF-β1)-treated renal interstitial fibroblasts. Aerobic glycolysis flux, indicated by glucose uptake and lactate production, was increased in mouse kidney with UUO nephropathy or TGF-β1-treated renal interstitial fibroblasts and positively correlated with fibrosis process. In line with this, we found that increasing aerobic glycolysis can remarkably induce myofibroblast activation while aerobic glycolysis inhibitors shikonin and 2-deoxyglucose attenuate UUO-induced mouse renal fibrosis and TGF-β1-stimulated myofibroblast activation. Furthermore, mechanistic study indicated that shikonin inhibits renal aerobic glycolysis via reducing phosphorylation of pyruvate kinase type M2, a rate-limiting glycolytic enzyme associated with cell reliance on aerobic glycolysis. In conclusion, our findings demonstrate the critical role of aerobic glycolysis in renal fibrosis and support treatment with aerobic glycolysis inhibitors as a potential antifibrotic strategy.

    Renal denervation (RDN) has been shown to reduce blood pressure (BP), muscle sympathetic nerve activity (MSNA) and target organ damage in patients with resistant hypertension (RH) and bilateral single renal arteries. The safety and efficacy of RDN in patients with multiple renal arteries remains unclear. We measured office and 24-hour BP at baseline, 3 and 6 months following RDN in 91 patients with RH, including 65 patients with single renal arteries bilaterally (group 1), 16 patients with dual renal arteries on either one or both sides (group 2) and 10 patients with other anatomical constellations or structural abnormalities (group 3). Thirty nine out of 91 patients completed MSNA at baseline and follow-up. RDN significantly reduced office and daytime SBP in group 1 at both 3 and 6 months follow-up (Pkidney function in any group. While RDN can be performed safely irrespective of the underlying renal anatomy, the presence of single renal arteries with or without structural abnormalities is associated with a more pronounced BP and MSNA lowering effect than the presence of dual renal arteries in patients with RH. However, when patients with dual renal arteries received renal nerve ablation in all arteries there was trend towards a greater BP reduction. Insufficient renal sympathetic nerve ablation may account for these differences. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    ESWL is now widely used for the treatment of renal stone disease. Although ESWL has many advantages for patients' quality of life, few reports have demonstrated the long-term outcomes of the alterations of renal morphology after ESWL. We reported renal scarring after ESWL monotherapy in patients with renal calyceal stones. In this study, we evaluated a large series of patients' cohort treated at our institution, and assessed the causal effect of ESWL on the late occurrence of renal scar formation. ESWL was performed with EDAP (LT-01,02) that generates shock wave energy by piezoelectric discharge. We analyzed the records of 285 kidneys treated between Dec. 1986 and Nov. 1998. Renal scarring was noted in 44 kidneys and not in 241 kidneys with periodical ultrasonography. We compared the backgrounds of the two groups using chi-square or non-parametric analysis. The Kaplan-Meier method and Cox regression model determined the analysis of renal scar formation. Univariate and multiple regression analysis revealed that the total amount of ESWL emission and hyperuricemia independently affected the probability of renal scar formation. Over-emission of ESWL (over 10,000 shots) must be care for the prevention of renal scarring in patients with renal calyceal calculi, especially when associated with hyperuricemia. After ESWL, periodical checkups with ultrasonography will provide useful information for the clinical diagnosis of renal scarring.

    We report the case of a 46-year-old woman with acute febrile symptom who had multiple pulmonary nodules and a renal mass. She underwent 18 F-fluorode-oxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) to find a hidden malignancy and the cause of her fever. FDG PET/CT images demonstrated a renal mass and multiple lung nodules with intense FDG uptake, which was suspicious of a renal malignancy with multiple pulmonary metastatic lesions. CT-guided biopsies of the pulmonary and renal lesions only showed chronic inflammatory infiltrates without evidence of malignancy. She was diagnosed with septic pulmonary embolism from a renal abscess. One month after antibiotic treatment, the follow-up chest and abdomen CT showed improvement of the lung and renal lesions. This is the first case demonstrating the FDG PET/CT finding of septic pulmonary embolism associated with renal abscess in the published literature. (author)

    The renal quantitative scintillation camera study assesses glomerular filtration rate and effective renal plasma flow based upon renal uptake of 99mtechnetium-iron ascorbate and 131iodine-hippuran, respectively. The method was compared to inulin, para-aminohippuric acid and creatinine clearance studies in 7 normal subjects and 9 patients with various degrees of reduced renal function. The reproducibility of the technique was determined in 15 randomly selected pediatric patients. The values of glomerular filtration rate and effective renal plasma flow were not significantly different from those of inulin and para-aminohippuric acid studies. The reproducibility of the technique was comparable to that of inulin and para-aminohippuric acid studies. Patient acceptance of the technique is excellent and the cost is minimal. Renal morphology and excretory dynamics also are demonstrated. The technique is advocated as a clinical measure of renal function
