ABSTRACT

OBJECTIVE: The increase of healthcare pressure in Emergency Departments compels us to have a better understanding of patients' characteristics and the pathology they consult for. This is the first study that estimates the waiting time in the emergency room and the factors that are independently related with hospital admission. METHODS: Descriptive and retrospective study of 2.741 patients who were admitted to the Emergency Department with genitourinary symptoms in 2011. Clinical and epidemiological features were reviewed. A multivariable study was performed to identify the factors related with the final resolution of patients, recurrence emergency attendance, and waiting time in the emergency room. RESULTS: Most of the patients were male (60.3%), being diagnosed with hematuria, acute urinary retention and genital pathology. Females complained more frequently for pyelonephritis, urinary tract infection and low-back pain. Male were hospitalized in greater proportion. Age, diagnosis of infection/sepsis or low-back pain, and yellow or orange MTS level were independent features for hospital admission. Also, in the univariate and multivariate study, age > 60 years (311 vs 220 min.), UTI/sepsis related diagnoses (300 vs 250 min.), and hospital admission as final resolution (440 vs 240 min.) had a significant influence in the waiting time in the Emergency Department. CONCLUSIONS: Age over 60 years, hospital admission as final resolution and infection/sepsis diagnosis were independent features for further waiting time in the Emergency Department. Persistent pain and symptoms of infection/sepsis behaved as independent features for hospital admission.


OBJETIVO: El aumento de la presión asistencial de los servicios de urgencias hospitalarios obliga a conocer las características de los pacientes y de los procesos por los que acuden. Este estudio es el primero que calcula tiempo de permanencia en urgencias y factores que se relacionan de manera independiente con ingreso hospitalario.MÉTODOS: Estudio descriptivo y retrospectivo de 2.741 pacientes que acudieron a Urgencias por sintomatología genitourinaria en el año 2011. Se examinaron rasgos clínicos y epidemiológicos. Se realizó un análisis multivariable para conocer los factores relacionados con la resolución final de los pacientes, recurrencia en la asistencia a urgencias y tiempo en urgencias. RESULTADOS: La mayoría de pacientes fueron varones (60,3%), con diagnósticos de hematuria, RAO y patología genital. Las mujeres, presentaron pielonefritis, ITU y dolor lumbar de manera más frecuente. Los varones ingresaron en mayor proporción. La edad, el diagnóstico de infección/sepsis o dolor lumbar y un nivel MTS amarillo o naranja, resultaron ser factores independientes de ingreso. Tanto en el estudio univariable como multivariable, la edad mayor de 60 años (311 vs 220 min), los diagnósticos relacionados con ITU y sepsis (300 vs 250 min) y el ingreso hospitalario como resolución final (440 vs 240 min) influyeron de forma significativa en el tiempo de estancia en Urgencias. CONCLUSIONES: La edad > 60 años, el resultado de ingreso y el diagnóstico de infección/sepsis fueron factores independientes de mayor tiempo en Urgencias. La presencia de dolor persistente y de infección/sepsis se comportaron como factores independientes de ingreso.

ABSTRACT

Introducción: Evaluamos, en cuanto a recurrencia, los factores pronósticos en el cáncer vesical no infiltrante de músculo y el efecto de la terapia intravesical. Material y métodos: Estudiamos 419 neoplasias vesicales. Realizamos análisis univariados y multivariados sobre 24 variables de estas neoplasias y valoramos distintos tratamientos. Resultados: Existieron diferencias significativas en el tiempo libre hasta la recurrencia, que fue menor en los tumores que recurrieron en menos de 12 meses, en los tumores múltiples (3 o más tumores) y de cúpula; además existieron diferencias estadísticamente significativas cuando se estudiaron dos grupos homogéneos de cirujanos.El empleo de instilaciones vesicales incrementó de forma independiente el tiempo hasta la recidiva. Se demostró que la recurrencia se produjo significativamente más tarde cuando se habían empleado dosis altas de BCG y terapia de mantenimiento. Conclusiones: Los siguientes factores resultaron independientes para explicar menor tiempo libre hasta la recurrencia superficial: recidiva en el primer año, multiplicidad, técnica quirúrgica, no empleo de lavados intravesicales, tratamiento con dosis bajas de BCG y terapia de inducción frente a mantenimiento. El empleo de instilaciones vesicales, con dosis altas de BCG y terapia de mantenimiento, incrementó de forma independiente el tiempo hasta la recidiva.(AU)

ABSTRACT

BACKGROUND AND OBJECTIVE: The aim of this study was to analyze the significance of anemia as well as other prognostic factors influencing survival in patients with renal cell carcinoma (RCC). PATIENTS AND METHODS: A retrospective review of data of 316 patients who underwent surgery between 1970 and 2003 was performed. Most important known prognostic factors of RCC were investigated. RESULTS: Most of patients had T1b-T2, low nuclear grade and single tumours. In 8.2% and 9% of cases, lymph node and metastatic dissemination were detected at the time of diagnosis, respectively. At the beginning, most frequent symptoms were hematuria and pain, with anemia (Hb >10g/dl) in 69 patients. After a median follow-up of 50 months, 24.1% of patients had a recurrence. From these, more than 50% developed recurrence within one year after nephrectomy. Advanced tumours (T3-4) consisted of high nuclear grade (III-IV) tumours, larger size tumours, with necrosis and vascular infiltration in surgical specimen, as well as lymph node and metastatic dissemination. In multivariate analysis, anemia, time to recurrence, type of treatment for recurrence as well as lymph node dissemination were independent factors of cancer specific survival. CONCLUSION: Anemia seems to be a marker of recurrence and progression in patients with renal cell carcinoma undergoing nephrectomy. From our point of view, anemia could be considered a significantly high mortality rate for renal cancer in these patients.

ABSTRACT

Fundamento y objetivo: Valorar el significado pronóstico de la anemia para el carcinoma de células renales (CCR), así como otros factores implicados en la supervivencia. Pacientes y método: Se realizó un análisis retrospectivo de los datos de 316 pacientes con carcinoma renal intervenidos entre los años 1970 y 2003. Se investigaron las principales características implicadas en el pronóstico de pacientes con CCR. Resultados: La mayoría de los tumores presentaron estadios bajos T1b-T2, con grados nucleares bajos (I–II) y un tumor único. En un 8,2% se encontró afectación ganglionar en el momento del diagnóstico y en casi un 9% existían metástasis a distancia. La clínica más frecuente al inicio fue hematuria o dolor, y la anemia (hemoglobina<10g/dl) estuvo presente en 69 casos Resultados: Con una mediana de seguimiento de 50 meses, recidivó un 24,1% de casos, de los que más del 50% ocurrió en el primer año tras la intervención. Los tumores avanzados (T3-4) tendieron a presentar un grado nuclear mayor (III–IV), más tamaño, necrosis, afectación vascular y ganglionar, asociándose más frecuentemente a metástasis a distancia. Los factores que influyeron de forma independiente en la mortalidad específica por cáncer fueron la presencia de adenopatías metastásicas, el tiempo libre de enfermedad en los casos con recidiva, así como el tratamiento de esa recidiva y la presencia de anemia. Conclusión: La existencia de anemia en pacientes intervenidos por carcinoma renal puede ser un marcador de recidiva y progresión de la enfermedad que implica, finalmente, un mayor riesgo de mortalidad por este tumor (AU)

ABSTRACT

OBJECTIVE: We report one case of ovarian metastasis secondary to a renal clear cell carcinoma. METHODS/RESULTS: 52 year-old consulting for metrorrhagia with the initial diagnosis of primary ovarian carcinoma. Tumor dissemination work up tests reported a renal mass suggestive of ovarian metastasis. Surgery included hysterectomy, double annexectomy, and radical nephrectomy. Final diagnosis was renal clear cell carcinoma with ovarian metastasis. CONCLUSIONS: Metastases to the ovary pose a diagnostic problem in their interpretation, especially when they show a similar histology to the primary ovarian tumor. Due to therapeutic and prognostic implications, it is very important to differentiate if it is a primary ovarian tumor or a metastasis from a renal carcinoma.

ABSTRACT

OBJECTIVES: To evaluate the prognostic significance of the 2002 TNM tumor classification for renal cell carcinoma, as well as other factors intervening in its survival. METHODS: Retrospective chart review of 316 renal carcinomas operated between 1970 and 2003. Twenty-five prognostic variables were analyzed. RESULTS: The histological type was renal cell carcinoma in 90.5% of the patients. Most tumors were T1b or T2, with a Fuhrman nuclear grade I or II. Mean tumor size was 7.17 +/- 3.4 cm. Most cases had a solitary tumor. 8.2% of the patients had lymph node involvement at the time of diagnosis, and 8.6% metastases. The most frequent clinical presentations were hematuria and/or pain. Mean follow-up was 57.8 months. 24.1% of the cases had recurrence, more than 50% of them during the first year. Advanced tumors (T3, T4) had the tendency to have a nuclear grade III-IV, bigger size, necrosis, vascular involvement, lymph node involvement, and metastases. At the end of follow-up, most patients were alive and disease free. The number of months free of disease, the presence of metastatic lymph nodes, the treatment of the first recurrence and the presence of anemia were independent factors for cancer specific mortality. CONCLUSIONS: The modification of the current classification of renal tumors pT3 and pT4 would help to a better decision-making in the therapy of tumors with vascular, perirenal fat or adrenal involvement. Anemia and treatment of the first recurrence are important factors for cancer specific survival.

ABSTRACT

OBJECTIVES: To review the influence of various intravesical treatments on superficial bladder cancer recurrence. METHODS: We retrospectively reviewed 473 superficial bladder neoplasias. Based on diagnosis and transurethral resection of bladder tumor (TUR BT), and depending on pathology, we proposed different adjuvant treatment and follow-up schemes. RESULTS: The following factors were independent risk factors for a longer recurrence-free time: intravesical instillations, high dose BCG, and maintenance therapy in comparison to induction. CONCLUSIONS: The use of intravesical instillations independently increases the time to recurrence. It was demonstrated that recurrence was significantly later when high dose BCG and maintenance therapy were employed.

ABSTRACT

Objetivo: Valorar el significado pronóstico de la clasificación tumoral TNM de 2002 para el carcinoma de células renales (CCR), así como otros factores implicados en la supervivencia. Métodos: Estudio retrospectivo de historias clínicas de 316 carcinomas renales intervenidos entre los años 1970 y 2003. Se analizaron 25 variables implicadas en el pronóstico de pacientes con CCR. Resultados: En un 90,5% de pacientes el tipo histológico fue de células renales. La mayoría de los tumores fueron T1b o T2, con un grado nuclear de Fuhrman I o II. La media del tamaño tumoral fue de 7,17 +/- 3,4 cm. En la mayoría de casos existió tumor único. En un 8,2% hubo afectación ganglionar en el momento del diagnóstico y en un 8,6% existían metástasis a distancia. La clínica más frecuente fue hematuria y/o dolor. El seguimiento medio fue de 57,8 meses. Recidivaron un 24,1% de los cuales más del 50% ocurrió en el primer año. Los tumores avanzados (T3, T4) tendieron a presentar un grado nuclear III-IV, mayor tamaño, necrosis, afectación vascular, afectación ganglionar y metástasis a distancia. Al finalizar el seguimiento la mayor parte de pacientes estaba vivo libre de tumor. Los factores que influyeron de forma independiente en la mortalidad cáncer específica fueron los meses libres de enfermedad, la presencia de adenopatías metastásicas, el tratamiento de la primera recidiva y la presencia de anemia. Conclusión: La modificación de la actual clasificación de los tumores renales pT3 y pT4, ayudaría a la mejor toma de decisiones en cuanto a la actitud terapéutica de tumores con afectación vascular, de grasa perirrenal y de glándulas adrenales. La anemia y el tratamiento de la primera recidiva son factores importantes implicados en la supervivencia cáncer específica (AU)

ABSTRACT

OBJETIVOS: Revisar la influencia de distintos tratamientos endovesicales sobre la recurrencia del cáncer vesical superficial. METODOS: Se revisaron retrospectivamente un total de 473 neoplasias vesicales superficiales. A partir del diagnóstico y la RTU vesical, y en función del resultado anatomopatológico, se plantearon distintos esquemas de seguimiento y tratamiento complementario. RESULTADOS: Resultaron independientes para explicar mayor tiempo libre hasta la recurrencia superficial los siguientes factores: empleo de lavados endovesicales, tratamiento con dosis altas de BCG y terapia de mantenimiento frente a inducción. CONCLUSIONES: El empleo de instilaciones vesicales incrementaron de forma independiente el tiempo hasta la recidiva. Se demostró que la recurrencia se produjo significativamente más tarde cuando se habían empleado dosis altas de BCG y terapia de mantenimiento (AU)
