ABSTRACT
Objetivo: Evaluar si la re-clasificación de los carcinomas renales de células claras (CRCC) en dos o tres grados de Fuhrman (GF) frente a la clasificación clásica mantiene su valor pronóstico. Material y métodos: Estudio sobre una cohorte de 383 CRCC tratados con nefrectomía radical/parcial (1990-2009). Se analizaron datos demográficos, evolución y supervivencia de los pacientes. Un uropatólogo reasignó los grados de Fuhrman de forma ciega al informe original. Para estudiar si se mantenía el valor pronóstico con las distintas clasificaciones se realizaron tres análisis de regresión múltiple de Cox, categorizando la variable grado en 4 categorías (I-II-III-IV), en tres (I+II-III-IV) y en dos (I+II-III+IV). Las variables explicativas fueron: edad, sexo, tamaño tumoral, estadio y grado. Las variables respuesta fueron: tiempo de supervivencia libre de progresión (recidiva locorregional /metástasis) y de supervivencia cáncer-específica. Resultados: La mediana de supervivencia global fue de 125 meses (IC 95%: 92-159). En los tres análisis multivariantes el grado de Fuhrman demostró valor predictivo independiente (p=0,0001) frente al estadio para la supervivencia libre de progresión y supervivencia cáncer-específica. El valor pronóstico se mantuvo en las nuevas clasificaciones. En la de tres categorías el paso del grado I+II al III presentó un RR: 2,31(p=0,0001) y del grado III al IV un RR: 2,47(p=0,0001) y en la de dos categorías se observó un RR: 2,8 (p=0,001) al pasar del grado I+II al III+IV. Conclusiones: La categorización en dos o tres grupos del grado de Fuhrman mantiene la capacidad predictiva sobre la supervivencia libre de progresión y cáncer-específica. Los grados III y IV presentan evoluciones distintas, por lo que la clasificación en tres categorías parece más adecuada para describir la evolución de estos pacientes (AU)
Objective: To evaluate if re-grading renal cell carcinoma (CRCC) in two or three-tiered grading schemes versus the traditional Fuhrman classification maintains the same prognostic value. Material and methods: A study of a cohort of 383 treated CRCC with radical or partial nephrectomy between 1990-2009 was made. We analyzed the demographic data, evolution and survival of these patients. An uropathologist reassigned the Fuhrman grades blindly to the first classification. In order to study if the prognostic value was maintained with the different classification, three Cox multivariate regression analysis were performed, classifying the variable of grade into four categories: (I-II-III-IV), into three (I+II-III-IV) and into two (I+II-III+IV). The explanatory variables were: age, gender, tumor size, study stage and grade. The response variables were progression-free survival (local-regional recurrence/metastasis) and cancer specific survival time. Results: The median overall survival was 125 months (95% CI: 92-159). In the three multivariate analyses carried out, the Fuhrman classification showed independent predictive value (p=:0.0001) compared to progression-free survival and cancer specific survival. The predictive power was maintained in the new classifications. In the three categories, the changing from grade I+II to III meant RR: 2.31 (p=0.0001) and from grade III to IV RR: 2.47 (p=0.0001) and in two-tiered classification an RR: 2.8 (p=0.001) was found when changing from I+II to III+IV. Conclusions: Our results show that categorizing the Fuhrman grade into three or two-tiered grading schemes provide the same predictive accuracy on progressive free survival and cancer specific survival. Grades III and IV have different outcomes so that the three-tiered classification seems to be more appropriate to described the course of these patients (AU)

OBJECTIVE: The aim of this study was to develop a postoperative prognostic nomogram for disease-free survival in patients with renal adenocarcinoma. MATERIALS AND METHODS: A total of 224 patients with organ-confined or locally advanced renal adenocarcinoma were treated with radical or partial nephrectomy. The variables included in the model were age, histological type, pathological stage, Fuhrman grade and DNA ploidy. Tumor recurrence was defined as any clinical evidence of recurrence. The probability of progression-free survival was calculated using the Kaplan-Meier estimate, and multivariate analysis was performed using a Cox regression. The nomogram was created using the data obtained from the Cox regression. RESULTS: Tumor recurrence was detected in 89 patients (39.74%). The median progression-free time in these patients was 9.55 months (range 0-133). Of these patients, 70.9% relapsed during the first 2 years, and only 15 patients (6.9%) were alive but ill at the end of the study. The probability of progression-free survival at 5 and 10 years was 66.64 and 61.97%, respectively. We performed a statistical validation of the model with accurate predictions that were discriminated with a confidence interval of 0.75 (comparing the predicted and actual probability). According to the nomogram obtained, patients with low-grade, diploid, organ-confined tumors would be candidates for follow-up not exceeding 5 years due to the low probability of recurrence (<40 points). CONCLUSION: The nomogram we developed is clinically relevant and can provide prognostic information for both patients and researchers. In addition, it can be used by researchers during the monitoring protocols that categorize patients based on their relative risk of disease progression.

OBJECTIVE: To evaluate the prognostic value of venous tumor thrombus in renal cell carcinoma. MATERIAL AND METHODS: A retrospective study of 167 patients with renal cell carcinoma and stage pT3 who underwent radical nephrectomy and extended lymphadenectomy from July 1969 to May 2008 was conducted. Patients with any kind of venous involvement were selected for the analysis (73 patients; 43.7%). The Kaplan Meier survival curves and log-rank test for comparisons were used for the survival analysis. Multivariate analysis was done by Cox regression. RESULTS: Lymph node involvement was present in 30 patients (41.1%) and metastatic disease in 9 patients (12.3%). The most frequent histologic renal cell carcinoma subtype was 50 (68.5%) conventional carcinoma, followed by nondifferentiated in 11 (15.5%), and chromophobe in 9 (12.3%). High grade tumors (Furhman 3-4) were present in 57% of the cases. Venous thrombus level extended to renal vein in 61 patients (83.6%), to inferior vena cava in 9 patients (12.3%) and to the cardiac right atrium in 3 cases (4.1%). The survival analysis showed worse survival in those patients with venous tumor thrombosis (p=.001) and with vein wall invasion (p=.0042), but not in function on the level of the thrombus (p=.12). The multivariate analysis identified the Furhman grade and venous tumor thrombosis as independent survival prognostic factors. CONCLUSIONS: In our series, venous tumor thrombosis, together with the Furhman nuclear grade, is an independent survival prognostic factor. However, neither cephalic extension of the thrombus nor the invasion of the vein wall showed independent prognostic value.

Objetivos: La retención aguda de orina (RAO) es poco frecuente en mujeres y puede relacionarse con distintas patologías. Sólo algunas pacientes son remitidas a una Unidad de Urodinámica para un estudio más exhaustivo. Se pretende describir las características y causas de RAO en las mujeres derivadas a nuestra unidad y analizar su evolución a medio plazo. Material y métodos: Estudio descriptivo retrospectivo (enero 1982- diciembre 2006) incluyendo las mujeres derivadas a la Unidad de Urodinámica tras sufrir una RAO. Se revisaron las historias clínicas con especial énfasis en antecedentes personales, exploración física, así como estudio urodinámico completo durante el episodio de RAO y una vez superado este. Resultados: Se incluyeron 202 mujeres, con una mediana de edad de 57 años (12- 87). Previamente 59 pacientes (28,7%) presentaban síntomas de vaciado. Los patrones urodinámicos que se encontraron fueron: 65 hipocontractilidad vesical (32,2%), 64 estudio normal (31,7%), 37 acontractilidad (18,3%), 21 obstrucción infravesical (10,4%) y 15 ausencia de relajación de suelo pélvico (7,4%). Las principales causas de RAO fueron: 53 neurológica (26,2%); 46 causa desconocida (22,8%); 19 ginecológica (9,4%); 22 diabetes mellitus (10,9%); y 16 urológica (7,9%). Deterioraron la función renal 14 mujeres (6,9%). Tras la RAO 106 mujeres (52,4%) necesitaron continuar con algún tipo de tratamiento. Conclusiones: En nuestra serie la RAO en mujeres suele ser consecuencia de una enfermedad neurológica o uroginecológica subyacente, aunque en un porcentaje importante de pacientes no se logra filiar la causa. La mitad de las pacientes se recuperaron totalmente y no precisaron ningún tipo de tratamiento (AU)
Objectives: Acute urinary retention (AUR) is uncommon in women and can be related to different conditions. Only some patients are referred to the urodynamics units for a more extensive study. We intend to describe the characteristics and causes of AUR in women referred to our unit and to analyze their middle term evolution. Material and Methods: We performed a descriptive retrospective study (January 1982-December 2006), including the women referred to our Uro-Neurology and Urodynamics Unit after suffering an AUR. Medical charts were reviewed with special emphasis on medical history, physical examination, and also complete urodynamics study during the AUR event and after its resolution. Results: A total of 202 women were included, median age of 57 years (12-87 years). Prior to the AUR, 59 women (28.7%) reported voiding symptoms. The urodynamics findings were: 65 (32.2%) detrusor hypocontractility; 64 (31.7%) normal study; 37 (18.3%) detrusor acontractility; 21 (10.4%) bladder outlet obstruction; 15 (7.4%) poor pelvic floor relaxation. The causes of the AUR were: 53 neurological (26.2%); 46 unknown (22.8%); 19 gynecological (9.4%); 22 diabetes mellitus (10.9%); 16 urological (7.9%). Renal insufficiency was observed in 14 patients (6.9%). After the AUR 106 women (52.4%) needed some kind of prolonged treatment. Conclusions: In our experience, AUR in the female is mainly related to underlying neurologic/urogynecologic disease, even though the etiology could not be known in a significant percentage of patients. Half of the patients recovered completely and did not require any treatment (AU)

BACKGROUND/AIMS: A correlation has been observed between DNA ploidy and other prognostic parameters such as tumor stage and grade. The present study evaluates tumor aneuploidization during renal adenocarcinoma expansion and growth. METHODS: A total of 252 renal tumors were analyzed between 1969 and 2001. Evaluated variables were age, TNM, Fuhrman classification, histology, size and DNA. A tumor was homogeneous when all the samples were diploid or aneuploid, and a heterogeneous tumor was the coexistence of aneuploid and diploid samples, or all-aneuploid with different aneuploid clones. RESULTS: A total of 224 tumors were included (coefficient of variation <8). The DNA study classified 129 (57.6%) as diploid and 95 (42.4%) as aneuploid. The percentage of aneuploid tumors increased significantly with the pathological stage. Both aneuploid patterns were also significantly more frequent in advanced pathological stages. Tumors with multiple aneuploid clones (n = 17) were significantly more frequent in tumors measuring `4 cm. Both aneuploid patterns showed no differences in survival (p = 0.83), indicating that the heterogeneous pattern probably represents an intermediate step between diploid and homogeneous aneuploid tumor status. CONCLUSIONS: The aneuploid pattern is more common in more advanced stages of the disease, with no clear correlation to primary tumor size. This suggests gradual aneuploidization with tumor expansion and growth.

OBJECTIVE: To describe the outcome of patients diagnosed of incidental prostate adenocarcinoma managed by watchful waiting. MATERIAL AND METHODS: We included patients with PSA< 4 ng/mL or higher with previous negative biopsy, who underwent surgery for BPH being diagnosed of incidental prostate adenocarcinoma. We performed a descriptive and retrospective study in patients with this diagnosis between 1992 and 2007. Salvage curative treatment was offered to those patients who progressed. Statistical analysis was performed using SPSS program. Progression variables were: age, preoperative and postoperative PSA, stage, Gleason score, prostate volume, initial treatment, PSA evolution and salvage treatment if necessary. RESULTS: 47 patients were diagnosed of incidental prostatic adenocarcinoma, finding an incidence of 4.25%. The medium follow up was 37 months. Of the patients who opted for watchful waiting, 72.5% remain on it. 11 patients progressed. Postoperative PSA and Gleason score showed up as prognostic variables of progression in T1a stage and postsurgery PSA did so in T1b patients. CONCLUSION: Watchful waiting is a useful option in patients with incidental prostate adenocarcinoma and favourable prognostic criteria. Postoperative PSA and Gleason score can predict progression in T1a stage and postoperative PSA in T1b stage.

INTRODUCTION: Nocturnal enuresis is a disorder with a maintained historical interest. Not only the multifactorial etiopathology, also its prevalence. OBJECTIVE: We consider reviewing the literature for knowing the problematic in the calculation of the prevalence of this disease. MATERIAL AND METHOD: We searched in Pubmed database with Mesh terms: "Enuresis", "Nocturnal Enuresis", we added in the search box terms bedwetting and epidemiology or prevalence. We included manuscripts in English and Spanish with more than 1000 patients as sample, we also included review papers. We analyzed the methodology and the prevalence, when it was possible, we stratified results in age, sex and the frequency of wet nights. RESULTS: The analyzed study's methodology is heterogeneous. Therefore comparisons are difficult. Due to the difficulty within the interpretation of the overall frequency, the results are not interesting unless methodology, age range of the sample and diagnosis criteria are previously detailed. CONCLUSIONS: An own epidemiology study is necessary in order to solve our problematic.

Introducción: La enuresis nocturna es un trastorno con un interés histórico mantenido, no solo en cuanto a su patogenia, probablemente multifactorial pero todavía hoy desconocida, sino también en cuanto a su frecuencia. Objetivo: Nos planteamos revisar la literatura médica al respecto para conocer la problemática en el cálculo de su casuística. Material y método: Realizamos una búsqueda en la base de datos PubMed, mediante los términos Mesh «enuresis», «nocturnal enuresis» y «bedwetting», e incluimos en el cuadro de búsqueda los términos «epidemiology OR prevalence». Incluimos todos los trabajos en lengua inglesa o española. Seleccionamos los trabajos con una muestra mayor de 1.000 pacientes, e incluimos estos y los artículos de revisión. Procedemos al análisis de la metodología empleada por los grupos más relevantes, así como los resultados globales de frecuencia; además, cuando es posible, estratificamos los resultados por edad, sexo y frecuencia de los escapes. Resultados: La metodología de los trabajos analizados es heterogénea y las comparaciones se hacen, por tanto, difíciles. La prevalencia global es difícil de estimar y dar resultados globales carece de interés pues para interpretarlos es necesario pormenorizar la metodología, la muestra y los criterios diagnósticos. Conclusiones: Se hace necesario un estudio epidemiológico propio que resuelva nuestra problemática (AU)

INTRODUCTION: Immunosuppressive treatment promotes development of neoplasms in kidney transplant patients. Cancer prevalence in these patients is 4 to 5 times higher as compared to the general population. Tumors are also known to behave more aggressively in transplant patients. OBJECTIVE: To perform a descriptive analysis of de novo urological tumors in kidney transplant patients and to analyze patient survival. MATERIALS AND METHODS: A retrospective study was conducted in 1751 transplant patients from January 1980 to December 2006. Patients in whom the tumor occurred in the first year after transplantation were excluded. The primary variables considered included sex, age at transplant, age at cancer diagnosis, site, clinical stage, treatment, and outcome. A Chi-square test was used for univariate statistical analysis. Survival was assessed using the Kaplan-Meier method. RESULTS: Twenty-nine de novo tumors (1.6%) were diagnosed in the 1751 transplanted patients, with a median follow-up of 35.28 months (2-121) from tumor diagnosis. Tumors were found in 24 males (82%) and 5 females (18%). Median age at transplantation was 50.8 (17-70) years, and median age at tumor diagnosis was 56.4 (19-79) years. Eleven patients (38%) were diagnosed with prostate cancer, seven (24%) with bladder tumors, 4 (60%) with non-muscle invasive tumors, and 3 (40%) with muscle invasive tumors. A renal adenocarcinoma in the primitive kidney was diagnosed in 6 patients (20%). Five patients (18%) were detected a tumor in the transplanted kidney. Median survival was 75 months for patients with bladder tumors, 82 months for prostate cancer, 59 months for tumors in the native kidney, and 86 months for graft tumors. CONCLUSIONS: In our series, de novo urological tumors in kidney transplant recipients were more common in males. Prostate cancer is the most common tumor and renal cell carcinoma of the native kidney has the worst survival rate.

INTRODUCTION: Spinal cord ischemia is a circulatory disorder of acute or subacute establishment and neurological clinic of medullar section, usually incomplete. We describe clinical and anatomical characteristics, as well as diagnostic methods and therapeuthic used in these patients. MATERIAL AND METHODS: Since 1987 to 2007, 65 patients were diagnosed of spinal cord ischemia in our hospital. Clinical interview, neurological examination and image study were performed. Urodynamic study was performed after medullar shock phase, including cystometry, pressure flow study and external urinary sphincter electromyography. We have reviewed treatment applied in these patients. RESULTS: 65 patients (27 women and 38 men), median age 63 years (15-87). 28 patients (43%) presented high lesion (upper to T7), 32 (49%) middle (T7-L2) and 4 (6%) low lesion (below L2). Flaccid paraplegia and acute urinary retention were the most frequent clinical findings at the begining. Aetiology was determined mainly by Magnetic Resonance. Urodynamic study revealed: 9 patients (47.4%) with high spinal cord lesion and detrusor overactivity (with or without dyssynergia), and 6 (31.5%) with arreflexia; 11 patients (47.8%) with middle spinal cord lesion and detrusor overactivity and 7 patients with arreflexia (30.4%); one patient with low spinal cord lesion and detrusor overactivity, and another one with arreflexia (33%). CONCLUSIONS: There is a good correlation among lesion level and clinical findings in traumatic spinal cord injuries, but this is not the same in spinal cord ischemia. Probably, incomplete and patched lesions in vascular spinal cord injuries could explain this lack of correlation. Therefore, it is mandatory to performe an exhaustive neurological and urological evaluation of these patients in order to select the best treatment and prevent upper urinary tract damage in the future.
