Association between benign prostate enlargement-related storage and voiding symptoms and systolic blood pressure: a single-center cross-sectional study

ABSTRACT BACKGROUND: Lower urinary tract symptoms significantly worsen quality of life. The hypothesis that they might lead to serious systolic blood pressure alterations through inducing sympathetic nervous activity has not been studied so far. OBJECTIVES: To investigate the relationship between benign prostate enlargement-related storage and voiding symptoms and systolic blood pressure. DESIGN AND SETTING: Cross-sectional single-center study on data from a hospital patient record system. METHODS: We evaluated the medical records of all consecutive patients with benign prostate enlargement-related lower urinary tract symptoms admitted between January 2012 and December 2017. Storage and voiding symptoms were assessed separately. International Prostate Symptom Score, uroflowmetry, postvoiding residual urine volume and systolic blood pressure were recorded. Pearson correlation and linear regression analysis were used. RESULTS: Positive correlations were found between systolic blood pressure and all of the storage symptoms. Among these, urgency had the most significant effect. There were 166 patients (41.4%) with urgency for urination, which increased mean systolic blood pressure from 124.88 mmHg (average value in elevated blood pressure group) to 132.28 mmHg (average value in stage-1 hypertension group). Hesitancy in urinating and feeling of incomplete bladder emptying had weak positive correlations with systolic blood pressure. There was a negative correlation between systolic blood pressure and intermittency of urination. CONCLUSIONS: With increasing numbers of urine storage symptoms, systolic blood pressure also increases, while the opposite occurs for voiding symptoms in patients with benign prostate enlargement. We conjecture that storage symptoms may lead to this increase through inducing sympathetic hyperactivity. Further prospective studies with larger groups are needed to confirm these findings.

Relationship between visual prostate score (VPSS) and maximum flow rate (Qmax) in men with urinary tract symptoms

ABSTRACT Objective: To evaluate correlation between visual prostate score (VPSS) and maximum flow rate (Qmax) in men with lower urinary tract symptoms. Material and Methods: This is a cross sectional study conducted at a university Hospital. Sixty-seven adult male patients>50 years of age were enrolled in the study after signing an informed consent. Qmax and voided volume recorded at uroflowmetry graph and at the same time VPSS were assessed. The education level was assessed in various defined groups. Pearson correlation coefficient was computed for VPSS and Qmax. Results: Mean age was 66.1±10.1 years (median 68). The mean voided volume on uroflowmetry was 268±160mL (median 208) and the mean Qmax was 9.6±4.96mLs/sec (median 9.0). The mean VPSS score was 11.4±2.72 (11.0). In the univariate linear regression analysis there was strong negative (Pearson's) correlation between VPSS and Qmax (r=848, p<0.001). In the multiple linear regression analyses there was a significant correlation between VPSS and Qmax (β-http://www.blogapaixonadosporviagens.com.br/p/caribe.html after adjusting the effect of age, voided volume (V.V) and level of education. Multiple linear regression analysis done for independent variables and results showed that there was no significant correlation between the VPSS and independent factors including age (p=0.27), LOE (p=0.941) and V.V (p=0.082). Conclusion: There is a significant negative correlation between VPSS and Qmax. The VPSS can be used in lieu of IPSS score. Men even with limited educational background can complete VPSS without assistance.

¿Es posible aumentar la especificidad para la realización de biopsia prostática en pacientes con PSA entre 4-10 ng/ml con cociente PSA libre/PSA total < 20%? / Is it possible to increase the specificity for the performance of prostatic biopsy in patients with PSA between 4 and 10 ng/ml and free/total PSA ratio 20%?

OBJETIVO: En la actualidad sigue siendo un problema la toma de decisión para realizar biopsia de próstata en pacientes con PSA entre 4-10 ng/ml, a pesar del uso del cociente PSA libre/ PSA total. El objetivo de este estudio es investigar la manera de aumentar la especificidad en la toma de decisión de la realización de biopsia de próstata en este tipo de pacientes. MÉTODOS: Desde enero a diciembre de 2014, se incluyen en este estudio hombres con PSA entre 4-10ng/ml y cociente PSA libre/ PSA total <20%, candidatos a biopsia de próstata. Se excluyen del estudio pacientes que estén tomando inhibidores de la 5 alfa-reductasa y pacientes con biopsias de próstata previamente realizadas. Se analiza edad, PSA total, testosterona total, libre y biodisponible, FSH, LH, SHBG, 17-hidroxiprogesterona, Androstendiona, volumen prostático (medido por ecografía transrectal), cocientes testosterona total/PSA, testosterona libre/PSA, testosterona biodisponible/PSA y Densidad de PSA, testosterona total/volumen próstata, testosterona libre/volumen próstata y testosterona biodisponible/volumen próstata. Análisis estadístico con SPSS 20,0 y significación estadística p≤0,05. RESULTADOS: Un total de 109 pacientes se incluyeron, divididos en 2 grupos según resultado de la biopsia. Grupo 1: 49 pacientes con biopsia de próstata positiva; Grupo 2: 60 pacientes con biopsia de próstata negativa. Se observan diferencias estadísticamente significativas en relación al volumen prostático (Grupo 1: 37,6 cc; Grupo 2: 52,8 cc; p = 0,04), densidad PSA (Grupo 1: 0,24; Grupo 2: 0,17; p = 0,002), testosterona total/volumen próstata (Grupo 1: 0,15; Grupo 2: 0,10; p = 0,02), testosterona libre/volumen próstata (Grupo 1: 0,002; Grupo 2: 0,001; p = 0,01) y testosterona biodisponible/volumen próstata (Grupo 1: 0,06; Grupo 2: 0,04; p = 0,007). Se realiza curva ROC para determinación de punto de corte con especificidad 90%, observando que un volumen de próstata menor a 60,7cc, una densidad de PSA mayor a 0,27 y un valor testosterona biodisponible/volumen próstata mayor a 0,07. CONCLUSIÓN: La decisión de biopsia de próstata en pacientes con PSA entre 4-10 ng/ml con cociente PSA libre/PSA total < 20% sigue siendo controvertida, no obstante podemos optimizar la decisión utilizando otros parámetros como el volumen de próstata, la densidad PSA y el cociente testosterona biodisponible/volumen próstata

OBJECTIVE: To investigate the manner to increase specificity in the decision-making process for the performance of prostate biopsy. METHODS: We include in this study men with PSA between 4 and 10 ng/ml and free/total PSA < 20%, candidates for prostate biopsy. Patients receiving 5 alpha reductase inhibitors or with previous biopsies were excluded. Analyzed variables: total PSA, total testosterone, free and bioavailable testosterone, FSH, LH, SHBG, 17 hydroxyprogesterone, Androstenedione, prostatic volume measured by transrectal ultrasound, total testosterone/PSA, testosterone/free PSA, bio available testosterone/PSA and PSA density, total testosterone/prostate volume, free testosterone/prostate volume and bioavailable testosterone/prostate volume. RESULTS: A total 109 patients have been included, divided into 2 groups according to the results of the biopsy. Significant differences were observed in prostatic volume (Group 1: 36.6cc and Group 2: 52.8 cc; p = 0.04), PSA density (Group 1: 0.24 Group 2: 0.17; p = 0.002), total testosterone/prostate volume (Group 1: 0.15 and Group 2: 0.10; p = 0.02) free testosterone/ prostate volume (Group 1: 0.002 Group 2: 0.001; p = 0.01) and bioavailable testosterone/prostate volume (Group 1: 0.06 Group 2: 0.04; p = 0.007). CONCLUSION: The decision for a prostate biopsy on patients with a PSA between 4-10 ng/ml with free/total ratio < 20% continues to be an issue, however, we can optimize decision using other parameters such as prostate volume, PSA density and bioavailable testosterone/prostate volume

The role of prolactin in prostatic inflammation / O papel da prolactina na inflamação prostática

Several reports have shown that prolactin (PRL) plays a role in prostatic growth, but few studies considered the role of PRL in the process of prostatic inflammation. Young (45 ± 5 days old) and adult (75 ± 5 days old) male Wistar rats were subcutaneously injected daily with domperidone (4.0 mg.kg-1) to maintain high serum PRL levels. The animals were treated for 15, 30, 45 or 60 days. Blood and prostate samples were collected at the end of each treatment for PRL dosage and histological analysis, respectively. Only young animals treated with DOMP for 15 and 30 days displayed inflammatory infiltrate in the prostate. These results confirm literature data in regards to PRL involvement in inducing prostate inflammation. Moreover, it was concluded that young animals are more susceptible then adults to the PRL action concerning prostate inflammation...

A prolactina (PRL) influencia o crescimento prostático, entretanto poucos estudos investigaram o papel da PRL na inflamação prostática. Ratos Wistar jovens (45 ± 5 dias de idade) e adultos (75 ± 5 dias de idade) receberam injeções subcutâneas diárias de domperidona (4,0 mg.kg-1) para manter níveis séricos altos de PRL. Os animais foram tratados por 15, 30, 45 ou 60 dias. Amostras de sangue e próstata foram coletadas ao final dos tratamentos para dosagem de PRL e análise histológica, respectivamente. Apenas os animais jovens tratados com domperidona por 15 e 30 dias apresentaram infiltrado inflamatório na próstata. Esses resultados confirmaram a participação da PRL na indução da inflamação prostática. A conclusão obtida foi que animais jovens são mais susceptíveis à ação da PRL na inflamação da próstata que os adultos...

Calidad de vida después recidiva bioquímica en los pacientes con cáncer de próstata. ¿Cómo y cuánto viven los pacientes después de recidiva bioquímica? / Quality of life after biochemical recurrence in patients with prostate cancer. How and how long do patients live after biochemical recurrence?

La monitorización rutinaria de PSA en pacientes con cáncer de próstata localizado tratados radicalmente permite identificar aquellos con recurrencia bioquímica exclusiva. Las opciones de tratamiento para el fallo bioquímico incluyen observación, cirugía, radioterapia externa sola o asociada a hormonoterapia, braquiterapia, crioterapia y hormonoterapia exclusiva. Estos tratamientos determinan un patrón específico de cambios (función urinaria, intestinal, sexual y hormonal) que puede impactar negativamente sobre la calidad de vida, de manera que su indicación debe realizarse de una manera juiciosa y siempre en consonancia con las expectativas y preferencias de los pacientes. Las decisiones sobre cómo y cuándo tratar un fallo bioquímico son complicadas y el impacto de las terapias de rescate sobre el resultado clínico final es desconocido. Las tasas de control del cáncer de próstata tras tratamiento de rescate con prostatectomía, crioterapia ó braquiterapia oscilan entre el 20-80% de los casos en función de las características de los pacientes seleccionados. Dado que los individuos con fallo bioquímico pueden estar clínicamente asintomáticos durante muchos años sin tratamiento es esencial que médicos y pacientes dispongan de un claro conocimiento del potencial impacto de las mismas sobre la calidad de vida(AU)

Routine monitoring of PSA in patients with localized prostate cancer radically treated permits to identify those with biochemical recurrence only. Treatment options for biochemical failure include observation, surgery, radiotherapy alone or combined with hormonal therapy, brachytherapy, cryotherapy and hormone therapy exclusively. These treatments determine a specific pattern of changes (urinary function, bowel, sexual and hormonal) that can negatively impact the quality of life, so that the indication must be made in a judicious way and always in consonance with patient’s expectations and preferences. Decisions on how and when to treat biochemical failure are complicated and the impact of salvage therapy on clinical outcome is unknown. Rates of prostate cancer control after salvage therapy with prostatectomy, brachytherapy or cryotherapy vary between 20-80% of cases according to selected patient characteristics. Because individuals with BF may be clinically asymptomatic for many years without treatment, it is essential that physicians and patients have a clear understanding of the potential impact of these on the quality of life(AU)

Correlation between the presence of inguinal hernia and the intensity of lower urinary tract symptoms / Correlação entre a presença de hérnia inguinal e a intensidade dos sintomas do trato urinário inferior

PURPOSE: To verify the correlation between the presence of IH and the intensity of LUTS related to BPH quantified through the International Prostate Symptom Score (IPSS). METHODS: We prospectively selected 52 patients over the age of 55years; Patients were divided into 2 groups. Group 1: composed of 32 patients with IH; Group 2 (control group): composed of 20 patients with no clinical evidence of IH. All patients were assessed using the IPSS, uroflowmetry (Qmax), post-void residual urine volume (PVR) and prostate volume (PV). RESULTS: Groups 1 and 2 presented no difference in PV (p>0.05) and uroflowmetry (Qmax) (p>0.05). There was a statistical significant difference between the PVR mean values between groups 1 and 2. The presence of IH correlated with a higher IPSS score (r=0.38 p<0.05) despite the fact the no difference was detected between the incidence of patients with mild, moderate and severe LUTS in groups 1 and 2. CONCLUSION: Patients with IH present higher IPSS. The role of IPSS as a marker to predict the development of clinical IH still to be determined.

OBJETIVO: Verificar a correlação entre a presença de HI e a intensidade dos STUI quantificados através do escore internacional de sintomas prostáticos (IPSS). MÉTODOS: Foram selecionados prospectivamente 52 pacientes com idade superior a 55 anos; os pacientes foram divididos em 2 grupos. Grupo 1: composto por 32 pacientes portadores de IH, Grupo 2 (grupo controle): composto por 20 pacientes sem evidência clínica de IH. Os parâmetros avaliados foram: sintomas urinários, quantificados através do IPSS; fluxo urinário máximo (Qmax), obtido através da fluxometria livre; resíduo pós miccional (RM) e volume prostático (VP), obtido através do ultrassom transretal. RESULTADOS: Os grupos 1 e 2 não apresentaram diferença significativa em relação ao Qmax e VP (p>0.05). Foi detectada diferença estatística significativa entre em relação ao VR entre os grupos 1 e 2 (p<0.05). A presença de HI se correlacionou com o aumento da intensidade dos STUI (r=0,38; p<0.05). Não foi detectada diferença estatisticamente significativa entre a incidência de pacientes portadores de STUI, leve, moderado ou intenso entre os grupos 1 e 2. CONCLUSÃO: Pacientes portadores de HI apresentam escore de sintomas (IPSS) mais elevados, entretanto o papel dos sintomas urinários como um dos possíveis fatores causadores do aparecimento de HI ainda não foi determinado.

Células madre y medicina regenerativa en urología, 2ª parte: urotelio, vejiga, uretra y próstata / Stem cells and regenerative medicine in urology, part 2: urothelium, urinary bladder, urethra and prostate

Introducción: La investigación en terapia celular y medicina regenerativa, desarrollada en su mayor parte en torno al estudio de las células madre, está obteniendo resultados prometedores en todas las especialidades médicas. En urología están llevándose a cabo grandes avances en este campo, si bien existen ciertas dificultades, pues, por ejemplo, a fecha de hoy aún no ha sido posible la completa identificación y aislamiento de las células madre uroteliales ni prostáticas humanas, aunque muchos grupos se están acercando cada vez más a ello. Material y métodos: Realizamos una búsqueda electrónica mediante la base de datos Pubmed, tanto de artículos originales como de revisiones, utilizando los criterios de búsqueda stem cells urology, urothelial stem cells, bladder stem cells, prostate stem cells, urethra stem cells, cell therapy urology, tissue engeneering urology y regenerative medicine urology. Resultados: Hemos hecho una revisión de 30 trabajos publicados hasta noviembre de 2009, tratando con ello de hacer una recopilación lo más completa posible, para poder conocer un poco mejor los avances realizados en este campo, desde los inicios hasta nuestros días. Conclusión: Aunque existen aún importantes numerosas incógnitas, la mayor de ellas conseguir la identificación, aislamiento y cultivo de las células madre renales, uroteliales y prostáticas humanas, esto no debe impedir a los investigadores el poder trasladar los resultados obtenidos en el laboratorio a la clínica (AU)

Introduction: Investigation in cell therapy and regenerative medicine, mainly developed around stem cell research, is reaching promising results in every medical specialities. There are also being great advances in Urology, despite the difficulties researchers are facing, as complete identification and isolation of human urothelial and prostatic stem cells has not been possible yet, although many groups are close to achieve it. Material and methods: We performed an electronic research through the Pubmed database, of both original and review publications, with the following search criteria: "stem cells urology", "urothelial stem cells", "bladder stem cells", "prostate stem cells", "urethra stem cells", "cell therapy urology", "tissue engeneering urology" y "regenerative medicine urology". Results: We reviewed 30 articles published up to November 2009, trying to summarize thoroughly the most relevant findings and the last advances in this fild, from the first steps to this day. Conclusion: Despite the great lack of knowledge existing, especially the need for achieving the identification of kidney, urothelium and prostate stem cells, this shouldn’t prevent researchers from translating the laboratory results to the clinical work (AU)

Impact of infection on the secretory capacity of the male accessory glands

INTRODUCTION: Studies that compare the impact of different infectious entities of the male reproductive tract (MRT) on the male accessory gland function are controversial. MATERIAL AND METHODS: Semen analyses of 71 patients with proven infections of the MRT were compared with the results of 40 healthy non-infected volunteers. Patients were divided into 3 groups according to their diagnosis: chronic prostatitis NIH type II (n = 38), chronic epididymitis (n = 12), and chronic urethritis (n = 21). RESULTS: The bacteriological analysis revealed 9 different types of microorganisms, considered to be the etiological agents, isolated in different secretions, including: urine, expressed prostatic secretions, semen and urethral smears: E. Coli (n = 20), Klebsiella (n = 2), Proteus spp. (n = 1), Enterococcus (n = 20), Staphylococcus spp. (n = 1), M. tuberculosis (n = 2), N. gonorrhea (n = 8), Chlamydia tr. (n = 16) and, Ureaplasma urealyticum (n = 1). The infection group had significantly (p < 0.05) lower: semen volume, alpha-glucosidase, fructose, and zinc in seminal plasma and, higher pH than the control group. None of these parameters was sufficiently accurate in the ROC analysis to discriminate between infected and non-infected men. CONCLUSION: Proven bacterial infections of the MRT impact negatively on all the accessory gland function parameters evaluated in semen, suggesting impairment of the secretory capacity of the epididymis, seminal vesicles and prostate. These findings were associated with an infectious related significant increase of semen pH. None of the semen parameters evaluated can be suggested as a diagnostic tool for infection.

Morphometric analysis of the fate of secretory epithelial cells in the ventral lobe of the rat prostate during massive apoptosis

Orchiectomy causes marked, rapid involution of the prostatic secretory epithelium. Concurrently, macrophages, which in normal glands are small and rarely occur at the base of the secretory epithelium, increase in size and number. Apoptotic cells are engulfed by companion epithelial cells and also by macrophages. In secretory cells and macrophages, dense bodies progressively increase in number and store membranes derived from dead cells of the secretory epithelium. In this work, we examined the contributions of the various routes of disposal of demised secretory epithelial cells of the rat prostate, induced to enter in apoptosis by retrieval of androgen. Specifi cally, we sought to determine how much membrane surface area derived from apoptotic cells of the secretory epithelium could be stored in dense bodies, and how these data compared with the disposal of dead cells via the glandular lumen. Glands from unoperated controls (day 0) and from rats examined 12 h and 1, 2, 3, 4, 5, 6, 7, 8, and 9 days after orchiectomy were studied morphometrically. The total membrane surface area of rough and smooth endoplasmic reticulum, Golgi apparatus, mitochondria and vesicles declined from 6.75 x 103 ìm2 in non-castrated rats to 1.12 x 103 ìm2 nine days after castration. Similarly, the total surface area of the secretory epithelium decreased from 10.6 x 1011 ìm2 in non-castrated rats to 0.204 x 1011 ìm2 nine days after castration. Geometrical models revealed that 1 ìm3 of dense body accommodated at least 142 ìm2 of myelin-like membrane surface area. Three to four days after castration, the total volume of intramacrophage dense bodies peaked (~5 x 106 ìm3) and represented 1-2% of the volume of intraepithelial dense bodies (~4 x 108 ìm3). The minimum membrane surface area that could be stored in dense bodies of the secretory epithelium on post-castration days 0, 1, 2, 3, 4 and 9 was 1.4%, 9%, 16%, 23%, 28% and 44%, respectively, of the total membrane surface area of the...

Prostate Shape and Symptom Score in Benign Prostatic Hyperplasia

Prostates of the same volumes were found to have very variable shapes, that is, combinations of variably elongated width, height, and lengths. These were believed to be possible causes of the differences in the severity of both the obstructions and symptoms in the prostates even when their volumes were similar. We measured the transverse (width), anterior-posterior (height) and longitudinal (length) diameters of the prostates and the transition zone, and their calculated volumes using transrectal ultrasonography. To establish the relationship between the International Prostate Symptom Score (IPSS) and each of the dimensional parameters of the transition zone and the total prostate, 105 consecutive patients (mean age 66.43 +/- 9.24 years with a range o6f 46 to 90) who had voiding dysfunctions that were presumably related to BPH were analyzed using the t-test. Patients with conditions other than BPH were excluded. The results were as follows: 1. There was no significant correlation between the IPSS and any prostate volume parameter in the constant prostate volume conditions, because of the small numbers in each group. However, in the analysis of the total number of cases in all the volume categories, a significant correlation was found between the IPSS and some prostate dimensions; i.e., the longitudinal parameters in the total prostates (p < 0.01), and the transverse (p < 0.05) and longitudinal parameters (p < 0.05) in the transition zones. 2. Further investigations of the statistics of these significant parameters showed that prostates that were longer than 4 cm had significantly more severe symptoms than prostates shorter than 4 cm (p < 0.05), and that prostates with a ratio of length in the transition zone to the length in the total prostate ratio that was greater than 0.8 had significantly higher symptom scores than those with lower ratios (p < 0.05). When evaluating patients who have BPH, it is important to consider the shape of prostate. More aggressive treatment may be indicated in cases where the transition zone lengths exceeds 4 cm and the transition zone to total prostate length ratio exceeds 0.8.

El dilema de la andropausia y el reemplazo hormonal en el hombre mayor / The dilemma of andropause and hormone replacement in the aged man

Los niveles de testosterona plasmática disminuyen con el correr de los años, calculándose que en un 20-30 por ciento de los hombres mayores de 60 años tiene valores por debajo de lo normal. Este estado de déficit ha sido denominado PADAM (déficit parcial de andrógenos en hombres de edad, por sus siglas en inglés). Los andrógenos en el adulto actúan sobre varias estructuras, como el hueso, el músculo, la hematopoyesis y la función sexual. La terapia de reemplazo hormonal puede realizarse con medicación oral o inyectable, debiendo valorarse los riesgos potenciales, especialmente sobre la próstata, lo que requiere un estricto monitoreo

Carcinoma epidermoide vesical de tipo verrucoso asociado a esquistosomiasis / Verrucous vesical epidermoid carcinoma associated with achistosomiasis

Introducción: Presentamos un caso de carcinoma vesical en un paciente con esquistosomiasis del mismo órgano. Esta neoplasia es una complicación tardía que afecta a pacientes con infestación crónica no tratada. Métodos y resultados: Un paciente inmigrante presentó hematuria macroscópica de tres años de evolución con polaquiuria y nicturia. La ecografía y urografía intravenosa mostraron un vejiga de baja capacidad y pared engrosada, con asimetría y rigidez parietal izquierdo del suelo. La TAC fue sugestiva de neoplasia infiltrante en cara anterior. Se realizó el diagnóstico histopatológico de carcinoma epidermoide de tipo verrucoso asociado a esquistosomiasis vesical y uretral. Comentario: La infestación vesical por esquistosoma haematobio es una entidad que, a pesar de ser poco frecuente en nuestro medio, hay que tener presente por el aumento de la inmigración y los viajeros procedentes de países endémicos, ya que no diagnosticarse temprano puede llevar a graves complicaciones y comprometer la vida del paciente (AU)

Estudo estrutural, morfométrico e topoquímico do destino das células mortas nos epitélios secretores da próstata e da mama induzidos a sofrer apoptose maciça / Morphometric and topochemical studies on the fate of the dead cells in epithelia induced to suffer massive apoptosis

Apresentamos os resultados obtidos em estudos dos epitélios secretores do lobo ventral da próstata de ratos castrados e de glândula mamária de ratas em desmame induzido. Em ambas as glândulas o recrutamento de macrófagos e o destino das células epiteliais secretoras apoptóticas foram analisados näo só com observaçöes qualitativas e morfométricas ao MET mas tambée através de cortes de parafina submetidos à reaçäo para revelar o antígeno ED1, um indicador fiduciável da presença de macrófagos de rato. Ainda em cortes de parafina, uma abordagem de apariçäo de células apoptóticas foi feita usando a reaçäo de TUNEL. Baseados nas observaçöes ao microscópio eletrônico de que corpos apoptóticos dentro de macrófagos säo progressivamente compactados em corpos densos e que os corpos densos intra-epiteliais pareciam ser formados de modo similar, decidimos investigar se há algum fundamento para a suspeita de que a totalidade da área superficial de membranas epiteliais perdidas na apoptose maciça poderia ter sido progressivamente armazenada nos corpos densos dos macrófagos intra-epiteliais e nos corpos densos das células epiteliais

Evaluación clínica de la correlación entre el volumen prostático, el flujo urinario, la edad y el residuo posciccional en 250 pacientes con trastornos miccionales / Clinical evaluation of the correlation between prostatic volume (PV), peak flow rate (PFR), age, and post void residual urine (PVR) in 250 patients with lower urinary tract symptoms (LUTS)

Objetivo: Interpretar clínicamente los resultados de la correlación existente entre los parámetros objetivos que utilizamos en la evaluación de pacientes portadores de síntomas urinarios, en relación con la presencia de HPB. Material y métodos: se evaluó la variación de las relaciones entre el tscto rectal, la flujometría, el volumen prostático, la edad y el residuo, en 250 pacientes con síntomas urinarios. Resultados: El tamaño de la próstata aumentó con la edad, con un brusco incremento en la década de los 50 años (p<0,01), el Qmax fue menor (p<0,01) y el residuo fue más frecuente (p<0,01) cuanto más grande ( o más pesada) fue la próstata; del mismo modo se relacionó el menor flujo con la mayor prevalencia de residuo (p<0,01). mientras que la edad no demostró una influencia significativa (p>0.05) para condicionar estos resultados. Conclusión En los pacientes que consultan por trastornos miccionales en asociación con HPB clínicamente demostrable se observa una correlación estadísticamente significativa entre el mayor tamaño de la misma, un flujo bajo, menor de 10ml/s y la presencia de residuo posmicional clínicamente significativo, independientemente de la edad
