Prevalence and grade of malignancy differences with respect to the area of involvement in multiparametric resonance imaging of the prostate in the diagnosis of prostate cancer using the PI-RADS version 2 classification.

PURPOSE: The peripheral zone is histologically different from the transitional zone. The aim of this study is to analyze the differences between the prevalence and grade of malignancy of mpMRI-targeted biopsies that involve the TZ with respect to the PZ. METHODS: A cross-sectional study of 597 men evaluated for PC screening between February 2016 and October 2022 was conducted. Exclusion criteria were prior BPH surgery, radiotherapy, 5-alpha-reductase inhibitors treatment, UTI, mixed involvement of PZ-TZ or doubts, and central-zone involvement. Hypothesis contrast test was used to study differences proportions of malignancy (ISUP > 0) and significant (ISUP > 1) and high-grade tumor (ISUP > 3) in PI-RADSv2 > 2-targeted biopsies in PZ with respect to TZ, and logistic regression and hypothesis contrast tests were used to study the influence of the area of exposure as an effect-modifying factor in the diagnosis of malignancy with respect to the PI-RADSv2 classification. RESULTS: 473 patients were selected and 573 lesions biopsied (127 PI-RADS3, 346 PI-RADS4 and 100 PI-RADS5). A significant increase was described in the proportion of malignancy and significant and high-grade tumor in PZ compared to TZ (22.6%, 21.3%, and 8.7%, respectively). Significant increase in proportions and malignancy were described in cores targeted to PZ with respect to TZ, highlight the differences between PZ and TZ for ST (37.3%vs23.7% for PI-RADS4, 69.2%vs27.3% for PI-RADS5, respectively). Statistically significant linear trend was described increasing for malignancy, significant and high-grade tumors with respect to the PI-RADSv2 scores (change > 10%). CONCLUSION: Although the prevalence and grade of malignancy in the TZ is lower than in the PZ, PI-RADS4 and 5-targeted biopsies should not be omitted in this location, but PI-RADS3 could be.

Diagnostic evaluation and incorporation of PSA density and the prostate imaging and data reporting system (PIRADS) version 2 classification in risk-nomograms for prostate cancer.

PURPOSE: The diagnostic approach for prostate cancer still depends on PSA and DRE. OBJECTIVES: to evaluate the diagnostic validity of PSA-Density and PIRADSv2 as diagnostic tests regarding biopsy results, and to design nomograms that include all diagnostic variables for malignancy, significant tumor (ST) and high-grade tumor. METHODS: Cross-sectional study which included men with PSA ≥ 4 ng/ml and/or suspicious DRE, PIRADSv2 ≥ 3 lesions on multiparametric MRI and prostate biopsy. The gold standard test was the maximum ISUP of the targeted biopsy per patient (malignancy: ISUP ≥ 1, ST: ISUP ≥ 2, high-grade tumor: ISUP ≥ 4). Association and logistic regression tests were used and diagnostic validity parameters using PSA-Density and PIRADSv2 classification was analyzed. Nomograms were designed for malignancy, ST, and high-grade tumor using the best model selection procedure from all possible equations. RESULTS: 336 men with median age, PSA and PSA-Density of 67.7 years (IQR:12.6), 6.3 ng/ml (IQR:3.3) and 0.12 ng/ml/cc (IQR:0.10), respectively; 63 index lesions were PIRADS3, 204 PIRADS4, and 69 PIRADS5. 65.8% and 37.8% were malignant and ST, respectively. The significant positive association highlighted between malignancy and ST with age, DRE, PSA-Density and PIRADSv2. PSA-Density and PIRADSv2 ≥ 3 presented the highest sensitivity to detect malignancy, and their combination showed sensitivity nearly 95% (AUC:0.803). Nomograms for malignancy and ST included the variables age, DRE, PSA-Density, and PIRADSv2 with a sensitivity closely 91% (AUC:0.833), and a specificity of almost 85% for ST, exposing risk < 5% for ST when PSA-Density is < 0.15, not suspicious DRE and PIRADS3. CONCLUSION: PSA-Density and PIRADSv2 classification in risk nomograms can provide highly relevant information to increase the accuracy in the diagnosis of PC and ST.

OBJETIVO: Comparar la eficacia y seguridad de la profilaxis de las infecciones del tracto urinario (ITUs) con un complemento alimenticio que contiene D-manosa como principio activo principal (Manosar(R)), en comparación con otro preparado cuyo principio activo único son las proantocianidinas (PAC), ambos de liberación continuada, tras su administración durante24 semanas. MÉTODOS: Estudio experimental multicéntrico, aleatorizado y doble ciego. Se incluyeron 283 mujeres con historia de ITUs recurrentes sin evidencias de complicación. Se randomizaron 1:1 en dos grupos. En un grupo se administró 1 sobre diario oral de Manosar®, y en el otro 1 sobre diario oral de un compuesto de 240 mg de PAC de liberación continuada. Previo a la inclusión en el estudio se confirmó el episodio de ITU al menos por la sintomatología clínica y positividad del test de Combur. RESULTADOS: Se obtuvieron datos válidos de 184 pacientes con edad media de 49,5 años: 90 recibieron Manosar(R) y 94 PAC aislado. Un total de 72 pacientes padecieron una ITU por E.coli: 25 pacientes en el brazo con Manosar(R) frente a 47 pacientes en el grupo de PAC aislado, siendo esta diferencia estadísticamente significativa (p = 0,002). El tiempo libre de nuevas recurrencias de ITU fue de 98,6 días en el grupo tratado con Manosar(R) y de 84,6 días en el grupo con PAC aislado. CONCLUSIÓN: La toma oral de un sobre al día de Manosar(R) es eficaz y segura en la prevención de las ITUs recurrentes en la mujer, siendo superior a la toma oral de PAC aislado

OBJECTIVE: To compare the efficacy and safety in the prophylasis of urinary tract infections (UTIs) with a food supplement that contains D-mannose like active ingredient (Manosar(R)), in comparison to another preparation in which the active ingredient are the proanthocyanidins (PAC), both of them, in prolonged released, after, they was administered for 24 weeks. METHODS: A multicenter, randomized and double blind experimental study was carried out. 283 women with a history of recurrent UTIs without evidence of complication were included. They were randomized 1: 1 in two groups. In one group, 1 oral sachet of Manosar(R) a day was administered, and in the other group 1 oral sachet of a compound of 240 mg of continuous-release PAC. Prior to inclusion in the study, the episode of UTI was confirmed at least by the clinical symptoms and positivity of the Combur test.

INTRODUCCIÓN: La biopsia prostática por fusión se describe como superior a la biopsia transrectal sistemática para identificar lesiones sospechosas de carcinoma de próstata. OBJETIVOS: Evaluar la clasificación PIRADS propuesto por la Sociedad Europea de Radiología Urogenital para la detección de cáncer de próstata mediante RNM en una cohorte consecutiva de pacientes con RNM y biopsia guiada por fusión. MATERIAL Y MÉTODOS: Estudio observacional transversal. 87 pacientes con sospecha de cáncer de próstata sometidos a biopsia de próstata transperineal y fusión con RNM en nuestro centro. Describimos tumor significativo como Gleason ≥ 7(3 + 4), y carcinoma de alto riesgo como Gleason ≥ 8. Utilizamos la prueba de Chi-cuadrado para analizar la relación entre cáncer de próstata y PIRADS, así como regresión logística y pruebas de tendencia lineal, comparando las proporciones con medidas de intensidad de asociación. Empleamos el sistema HITACHI Real-Time Virtual Sonography y el software STATA/IC v.14.2 para el análisis estadístico. RESULTADOS: 64,37% pacientes presentaron resultado positivo para malignidad. Media de edad 67,89 años (SD 7,42), de PSA total 9,15 ng/ml (SD 7,85), y de volumen prostático 54,05 cc (SD 22,92). Se biopsiaron 124 lesiones sospechosas en RNM (25% PIRADS III, 57,26% PIRADS IV y 17,74% PIRADS V). 5/31 lesiones PIRADS III, 47/71 PIRADS IV y 18/22 PIRADS V fueron positivas para malignidad, con relación lineal estadísticamente significativa entre PIRADS y malignidad (p < 0,001), razón de prevalencias (RP) 4,10 (IC95% 1,81-9,32) para PIRADS IV, y RP 5,07 (CI95% 2,2211,59) para PIRADS V respecto a PIRADS III. 3,23% lesiones PIRADS III, 32,39% PIRADS IV y 63,64% PIRADS V correspondieron a tumores significativos.

INTRODUCTION: Prostate Fusion biopsy (MRI + prostate ultrasound) is described in literature as superior to classic random transrectal biopsy in order to identify suspicious lesion. OBJECTIVES: To evaluate the Prostate Imaging Reporting and Data System (PI-RADS) proposed by the European Society of Urogenital Radiology (ESUR) for detection of prostate cancer by multiparametric MRI in a consecutive cohort of patients with MRI and transrectal ultrasound prostate fusion-guided biopsy. MATERIAL AND METHODS: 87 patients with suspected Prostatic Cancer on prostate MRI underwent fusion transperineal prostate biopsy in our Department. 37 patients had at least one prior negative classic prostatic transrectal biopsy. Clinically significant tumor was described as Gleason 7(3+4) or higher. The Chi-square test was used to analyze the relationship between prostate cancer and the different PIRADS stages, as well as logistic regression and linear trend tests, comparing the proportions using measures of association intensity. We use the HITACHI Real-Time Virtual Sonography (HI-RVS) system, and the STATA/IC v.14.2 software for statistical analysis. RESULTS: 64.37% patients had tested positive for malignancy. Median age 67.89 years old. Median PSA 9.15 ng/ml, and average prostate volume was 54.05 cc. 124 suspicious lesions were described in prostate MRI (25% PIRADS III, 57% PIRADS IV and 17% PIRADS V). 5/31 lesions PIRADS III, 47/71 PIRADS IV and 18/22 PIRADS V were positive for malignancy, with a statistically significant linear relationship between PIRADS and malignancy (p < 0.001) - HR 4.10 (CI 95% 1.81 to 9.32) for PIRADS IV and HR 5.07 (CI95% 2.22 to 11.59) for PIRADS V vs. PIRADS III. 3.23% lesions PIRADS III, 32.39% PIRADS IV and 63.64% PIRADS V corresponded to significant tumors. A statistically significant association between PIRADS and significant tumors (p < 0.001) - HR 10.04 (CI95% 1.42 to 71.09) for PIRADS IV and HR 19.73 (CI95% 2.80 to 139.18) for PIRADS V vs PIRADS III was observed -. CONCLUSION: Our results show that transperineal targeted prostate biopsy using multiparametric MRI and transrectal ultrasound fusion is a safe procedure with excellent outcomes to obtain an accurate diagnosis of prostate cancer. Fusion biopsy has the potential to improve the diagnosis of malignancy and clinically significant tumors while reducing overdiagnosis

[Clinical and urodynamic risk factors of recurrent urinary tract infections in patients with multiple sclerosis.] / Factores de riesgo clínicos y urodinámicos de infecciones urinarias recurrentes en pacientes con esclerosis múltiple.

OBJECTIVES: To determine the risk factors of recurrent urinary infections (rUTIs) in patients with Multiple Sclerosis (MS). METHODS: A retrospective cohort study was conducted including 114 patients with MS, 84 women (74%) and 30 men (26%), with a mean age of 49. They underwent videourodynamic study and selective sphincter electromyography due to urinary symptoms (LUTS). Clinical data (both neurological and urological) and videourodynamic data (including free flowmetry, cystomanometry and pressure flow study) were collected. In 37 patients (32%), the presence of rTUIs was demonstrated. RESULTS: Statistically significant differences were demonstrated between the patients with and without rUTIs with respect to the following clinical variables: the time of evolution of the symptoms (greater in the case of rUTIs), time from the diagnosis of MS (higher in the case of rUTIs), EDSS score (Expanded Disability Staus Scale) (higher in the case of rUTIs) and the EM type [higher frequency of rUTIs in the progressive types (primary and secondary)]. Urodynamic variables with significant differences were: maximum flow in free flowmetry (lower in patients with rUTIs), voiding volume in free flowmetry (lower in patients with rUTIs), micturition efficiency (higher percentage of residual urine in patients with rUTIs), stress urinary incontinence (SUI) (higher frequency of rUTIs in patients with SUI), detrusor pressure at maximum flow (lower in patients with rUTIs) and bladder contractility index (lower in patients with rUTI). No significant difference was demonstrated in relation to the presence and type of neurogenic lower urinary tract dysfunction (NLUTD). CONCLUSIONS: The severity and duration of MS is a risk factor for rUTIs. Urodynamic risk factors are compatible with a lower contractile capacity in patients with rUTIs, while the existence of NLUTD would not imply any specific risk factor.

OBJETIVO: Determinar los factores de riesgo de infecciones urinarias recurrentes (rUTIs) en pacientes con Esclerosis Múltiple (EM).MÉTODOS: Se realizó un estudio de cohortes retrospectivo en 114 pacientes, 84 mujeres (74%) y 30 varones (26%), de edad media 49 años con EM sometidos a estudio videourodinámico y electromiografía selectiva esfinteriana por presentar síntomas urinarios (LUTS). Se recogieron los datos clínicos (tanto neurológicos como urológicos) y videourodinámicos (incluyendo flujometría libre, cistomanometría y estudio presión flujo). En 37 pacientes (32%) se demostró la presencia de rTUIs. RESULTADOS: Se demostraron diferencias estadísticamente significativas entre los pacientes con y sin rUTIs respecto de las siguientes variables clínicas: el tiempo de evolución de los síntomas (mayor en el caso de rUTIs), antigüedad de la EM (mayor en el caso de rUTIs), la puntuación EDSS (Expanded Disability Staus Scale) (mayor en el caso de rUTIs) y el tipo EM [mayor frecuencia de rUTIs en los tipos progresivos (primario y secundario)]. Las variables urodinámicas con diferencias significativas fueron: el flujo máximo en la flujometría libre (menor en pacientes con rUTIs), el volumen miccional en la flujometría libre (menor en pacientes con rUTIs), la eficiencia miccional (mayor porcentaje de residuo en pacientes con rUTIs), la incontinencia urinaria de esfuerzo (SUI) (mayor frecuencia de rUTIs en pacientes con SUI), la presión del detrusor a flujo máximo (menor en pacientes con rUTIs) y el índice de contractilidad vesical (menor en pacientes con rUTI). No se demostró ninguna diferencia significativa en relación con la presencia y tipo de disfunción neurógena del tracto urinario inferior (NLUTD). CONCLUSIONES: La gravedad y duración de la EM constituye un factor de riesgo para las rUTIs. Los factores de riesgo urodinámicos son compatibles con una menor capacidad contráctil en los pacientes con rUTIs, mientras que la existencia NLUTD no supondría ningún factor de riesgo específico.

Factores de riesgo clínicos y urodinámicos de infecciones urinarias recurrentes en pacientes con esclerosis múltiple / Clinical and urodynamic risk factors of recurrent urinary tract infections in patients with multiple sclerosis

OBJETIVO: Determinar los factores de riesgo de infecciones urinarias recurrentes (rUTIs) en pacientes con Esclerosis Múltiple (EM). MÉTODOS: Se realizó un estudio de cohortes retrospectivo en 114 pacientes, 84 mujeres (74%) y 30 varones (26%), de edad media 49 años con EM sometidos a estudio videourodinámico y electromiografía selectiva esfinteriana por presentar síntomas urinarios (LUTS). Se recogieron los datos clínicos (tanto neurológicos como urológicos) y videourodinámicos (incluyendo flujometría libre, cistomanometría y estudio presión flujo).

OBJECTIVES: To determine the risk factors of recurrent urinary infections (rUTIs) in patients with Multiple Sclerosis (MS). METHODS: A retrospective cohort study was conducted including 114 patients with MS, 84 women (74%) and 30 men (26%), with a mean age of 49. They underwent videourodynamic study and selective sphincter electromyography due to urinary symptoms (LUTS). Clinical data (both neurological and urological) and videourodynamic data (including free flowmetry, cystomanometry and pressure flow study) were collected. In 37 patients (32%), the presence of rTUIs was demonstrated. RESULTS: Statistically significant differences were demonstrated between the patients with and without rUTIs with respect to the following clinical variables: the time of evolution of the symptoms (greater in the case of rUTIs), time from the diagnosis of MS (higher in the case of rUTIs), EDSS score (Expanded Disability Staus Scale) (higher in the case of rUTIs) and the EM type [higher frequency of rUTIs in the progressive types (primary and secondary)]. Urodynamic variables with significant differences were: maximum flow in free flowmetry (lower in patients with rUTIs), voiding volume in free flowmetry (lower in patients with rUTIs), micturition efficiency (higher percentage of residual urine in patients with rUTIs), stress urinary incontinence (SUI) (higher frequency of rUTIs in patients with SUI), detrusor pressure at máximum flow (lower in patients with rUTIs) and bladder contractility index (lower in patients with rUTI). No significant difference was demonstrated in relation to the presence and type of neurogenic lower urinary tract dysfunction (NLUTD). CONCLUSIONS: The severity and duration of MS is a risk factor for rUTIs. Urodynamic risk factors are compatible with a lower contractile capacity in patients with rUTIs, while the existence of NLUTD would not imply any specific risk factor

Cambios funcionales en la fase miccional de varones diagnosticados de detrusor hipoactivo no neurogénico sometidos a cateterización vesical / Functional changes during the voiding phase in males with non-neurogenic detrusor underactivity undergoing bladder catheterization

Objetivos: Determinar los cambios urodinámicos de la fase miccional en varones con hipocontractilidad del detrusor (DU) sometidos a cateterismo vesical por retención urinaria. Métodos: De un total de 64 pacientes con retención urinaria, se realizó un estudio de seguimiento en 17 varones de edad media 77 años, diagnosticados urodinámicamente de DU por presentar un Índice de Contractilidad Vesical (BCI) menor de 100, sometidos a sonda vesical a permanencia (16 casos) o cateterismo vesical limpio intermitente (1 caso) por retención aguda de orina (14 casos), o residuo postmiccional patológico (3 casos). Los pacientes fueron sometidos a un segundo estudio urodinámico a los 13 meses de seguimiento de media. Las pruebas estadísticas utilizadas fueron el test exacto de Fisher para variables cualitativas y el test de comparación de media de la t de Student para variables paramétricas. El nivel de significación se fijó en p < 0,05 bilateral. Resultados: En el segundo estudio urodinámico, se observó un aumento significativo de la presión máxima del detrusor, la presión a flujo máximo, el BCI y el Índice de Obstrucción de Salida Vesical (BOOI) y del número de pacientes que orinaron durante el estudio presión/ flujo. Conclusiones: El cateterismo vesical en varones con DU mejora significativamente la contractilidad vesical y permiten desenmascarar obstrucciones del tracto urinario inferior que estaban ocultas por una insuficiente presión del detrusor en relación a la DU de estos pacientes. Esto podría tener no sólo aplicaciones diagnósticas, sino pronósticas y terapéuticas

Objectives: To investigate urodynamic changes during the voiding phase in males with detrusor underactivity (DU) undergoing bladder catheterization for urinary retention. Methods: From a total of 64 patients with urinary retention, a follow-up study was performed in 17 males with a mean age of 77 years. Patients received a urody namic diagnosis of DU based on a Bladder Contractility Index (BCI) score of <100 and underwent permanent bladder catheterization (16 cases) or clean intermittent catheterization (1 case) for acute urinary retention (14 cases), or post void residual urine (3 cases). Patients underwent a second urodynamic study after a mean 13 months of follow-up. Fisher’s exact test was used with categorical variables and Student’s t test with parametric variables. The level of significance was set at p < 0.05 for a two-sided test. Results: The second urodynamic study showed a significant increase in maximal detrusor pressure, pressure at maximum flow rate, BCI score, Bladder Outlet Obstruction Index (BOOI) score, and number of patients who urinated during the pressure-flow study. Conclusions: Bladder catheterization in men with DU significantly improves bladder contractility and revealed obstructions of the lower urinary tract that were masked by insufficient detrusor pressure in relation to the DU of these patients. These findings could have diagnostic as well as prognostic and therapeutic applications

[Efficacy and safety of D-mannose (2 g), 24h prolonged release, associated with Proanthocyanidin (PAC), versus isolate PAC, in the management of a series of women with recurrent urinary infections.] / Eficacia y tolerancia terapéutica de la D­manosa (2 g) de liberación prolongada 24 horas (asociada a proantocianidinas), frente a proantocianidinas aisladas en el manejo de una serie de mujeres con infecciones urinarias recurrentes.

OBJECTIVE: To compare the efficacy and safety of dietary supplement "Manosar®" composed of D-mannose (2 g), 24 h prolonged release, associated with Proanthocyanidin (PAC) (140 mg), ursolic acid (7.98 mg), A, C, and D vitamins and the oligoelement zinc, versus 240 mg of PAC in recurrent urinary tract infections (UTI), for a designed follow-up of 24 weeks, in women. METHODS: A multicenter randomized experimental double-blind study was carried out. The study was approved by review board of "Complejo Hospitalario de Toledo" (Spain), and all patients gave informed consent. A total of 150 women with non complicated UTI were screened for participation. Valid data was obtained from 93, with mean age of 48 years. Fortyfour patients were assigned to the Manosar® group and 51 patients to the PAC group. Patients were followed during six months. A previous UTI was defined based on a combination of symptoms and a positive reactive urine trip. Confirmation of a new UTI was based on symptoms, reactive urine strip and urine culture. RESULTS: Thirty-three patients (35%) had an UTI during the six months follow-up. The percentage of UTI of the Manosar® group during this period was 24%, while the percentage of the PAC group was 45% (p〈0.05). The disease-free time for the Manosar® group was 95 days, while this time was 79 days for the PAC group. The incidence of side effects was low. Diarrhea was the most frequent side-effect in both groups. CONCLUSION: Manosar® (oral once a day) is more effective than single dose PAC (240 mg daily orally) to prevent recurrent UTI in women.

Objetivo: Comparar la eficacia y seguridad de un complemento alimenticio (Manosar®) (2 gramos de D-manosa, 140 mg de PAC y 7,98 mg de ácido ursólico junto con las vitaminas A, C y E, y el oligoelemento Zinc) en la recurrencia de la ITU y su comparación con un compuesto basado con 240 mg proantocianidinas (PAC aislado), con una duración de administración esperada de 24 semanas. Métodos: Estudio experimental multicéntrico, aleatorizado y doble ciego. Aprobado por el Comité Ético de Investigación clínica del "Complejo Hospitalario de Toledo". Todos los pacientes firmaron el consentimiento. Se incluyeron 150 mujeres con historia de ITU recurrentes sin evidencias de complicación. Se obtuvieron datos válidos de 93 pacientes con edad media de 47,62 años. 42 recibieron Manosar y 51 PAC aislado. Controles cada 30 días durante 6 meses. La confirmación del episodio clínico previo de ITU fue definido al menos por la sintomatología clínica y tira de orina Combur (positiva a leucocito-esterasa y/o nitritos). La confirmación del nuevo episodio incidente durante el estudio fue confirmado por la sintomatología clínica, tira de orina y urinocultivo. Resultados: 33 pacientes (35,48%) padecieron una ITU durante el periodo de 6 meses de seguimiento. En el grupo tratado con Manosar® se observó ITU a los seis meses en un 23,8%, mientras que en el grupo control (PAC aislado) fue de 45,1% (p<0,05). El tiempo libre de enfermedad fue de 78,81 días en el grupo control (PAC aislado) y de 94,7 días en el grupo tratado con Manosar®. Se observó una baja incidencia de acontecimientos adversos, siendo la diarrea el más frecuente en ambos grupos. Conclusión: La toma oral de Manosar®, un sobre al día, es más eficaz que la toma oral de 240 mg de PAC aislado, un sobre al día, en la prevención de las infecciones urinarias de repetición en la mujer (AU)

Effect of pelvic organ prolapse repair on detrusor overactivity in women following incontinence surgery: A multivariate analysis.

AIMS: To determine the effect of pelvic organ prolapse (POP) repair on post-operative detrusor overactivity (DO) in women who have underwent incontinence surgery, using multivariate analysis. METHODS: A retrospective study was carried out on a cohort of 105 women who underwent incontinence surgery. In 39 of the patients this surgery was associated with pelvic organ prolapse repair. Clinical and urodynamic data were collected pre- and 3 months post-operatively. A multivariate statistical analysis was performed to detect confounding factors which could influence on the risk factors associated with post-operative detrusor overactivity. RESULTS: On univariate analysis, the following pre-operative factors were associated with post-operative detrusor overactivity: symptomatic mixed urinary incontinence, rectocele, detrusor overactivity, voided volume on free uroflowmetry, maximum cystomanometric capacity, and performing concomitant pelvic organ prolapse repair. Multivariate analysis, by means of confounding factors elimination, revealed that only pre-operative rectocele and detrusor overactivity were independent risk factors. CONCLUSIONS: The pelvic organ prolapse repair acts as a confounding factor. Women with a pre-operative rectocele and detrusor overactivity are on a greater risk to develop post-operative detrusor overactivity and, therefore, they should be informed.

Post Pelvic Radiotherapy Affectation of the Lower Urinary Tract Peripheral Innervation in Men.

INTRODUCTION: The periurethral electromyography (EMGs) alterations in men who underwent pelvic radiotherapy (RT), either isolated or combined with surgery, have not been frequently described in the literature. OBJECTIVE: The study aimed to compare the EMG's data in men undergoing RT versus the non-irradiated control group. MATERIAL AND METHODS: The study included 61 consecutive males, who had undergone RT (27 of them had been operated) and 99 control consecutive patients who underwent a retrospective assessment. The EMGs were performed using a concentric electrode needle perineally, localizing the sphincter by visual and auditory signal (electromyograph MMS Solar Active). RESULTS: 14.8% denervation, 62.9% reinnervation, 14.9% denervation + reinnervation and 7.4% EMG normal. The age (p < 0.001) and neurogenic bladder data (p < 0.001) are risk factors. The smaller the prostate size (obtained by rectal examination) post-RT, the more the chance for an abnormal EMG (p < 0.001). The fact of having had received RT (p < 0.001) is the only risk factor. CONCLUSION: RT produces lesions over the pudendal nerve, showing denervation even in late periods. The surgery did not behave as a risk factor.

[Prognostic factors for the efficacy of Silodosin in the treatment of symptomatic Benign Prostatic Hyperplasia. Subanalysis of the URAL study.] / Factores pronósticos de la eficacia de la Silodosina en el tratamiento de la Hiperplasia Benigna Prostática sintomática. Subanálisis del estudio URAL.

OBJECTIVE: To identify the prognostic factors influencing the clinical and urodynamics results on symptomatic benign prostatic hypertrophy (BHP) treatment in a series of patients with silodosin therapy from the URAL study. METHODS: A retrospective study was performed in a cohort of 318 patients with BPH which underwent silodosine treatment, during at least 12 weeks. RESULTS: Univariate analysis demonstrated that the variables in relationship with a decrease of urinary symptoms` punctuation postreatment (measured with the IPSS Questionnaire), a maximum peak flow (Q max) postreatment equal or superior to 15 ml/s, a postreatment postvoid residual lower to 100 ml, and a postreatment obstruction index ( Bladder Outlet Obstruction Index: BOOI) equal or lower to 20 cm H2O, presented such both as a clinical and urodynamic character. The multivariate analysis demonstrated that a decreased punctuation of IPSS Questionnaire postreatment was in relationship to: a pretreatment cystometry bladder capacity (direct relationship), pretreatment Qmax (direct relationship), pretreatment postvoid residual (inverse relationship), and pretreatment BOOI (inverse relationship). CONCLUSION: The urodynamic study was very useful in the assessment of the prognostic factors in these patients.

OBJETIVO: Determinar los factores pronósticos que influyen en el resultado clínico y urodinámicos del tratamiento de la hiperplasia benigna prostática (HBP) sintomática, en el subgrupo de pacientes tratados con silodosina, del estudio URAL. MÉTODOS: Se realizó un estudio (clínico y flujométrico) retrospectivo en una cohorte de 318 pacientes (en 40 de ellos, y de manera consecutiva, un estudio urodinámico completo) con HPB sometidos a tratamiento con silodosina al menos durante 12 semanas. RESULTADOS: El análisis univariante mostró que las variables relacionadas con: la disminución de la puntuación de síntomas urinarios medidas por el cuestionario IPSS, un flujo miccional máximo (Qmax) postratamiento superior o igual a 15 ml/s, un residuo postmiccional inferior a 100 ml y un índice de obstrucción (BOOI) inferior o igual a 20 cm H20, fueron tanto clínicas como urodinámicas. El análisis multivariante demostró que la mejoría del IPSS estaba condicionada por la capacidad vesical cistomanométrica previa (relación directa) y la del Qmax (relación directa), residuo postmiccional (relación inversa) y BOOI (relación inversa) por sus valores previos al tratamiento. CONCLUSIONES: El estudio urodinámico demuestra su utilidad en la valoración de estos factores pronósticos

[Usefulness of urodynamics in the treatment of mixed urinary incontinence in women with suburethral slings]. / Utilidad de la urodinámica en el tratamiento de la incontinencia urinaria femenina mixta con slings suburetrales.

OBJECTIVE: The urodynamic results in suburethral slings (SS), are contradictory. We evaluate a series on patients with stress urinary incontinence (associated or not with bladder hyperactivity) that underwent suburethral slings (SS) operations. METHODS: 42 women (age 62±12 years) with urinary incontinence underwent suburethral slings (86% TOT, 12% TVT, 2% others), 36% of them with simultaneous pelvic organ prolapse correction. Medical history and a pre and postsurgery urodynamic studies (according to ICS instructions, except when specified) were performed. RESULTS: After surgery, the improvement of urinary incontinence was lower in patients with previous detrusor hyperactivity (DH) than without DH (60% vs 81 %), and the bladder capacity (BC) was lower (123±36 ml) in patients with previous mixed urinary incontinence (MUI) versus no MUI (241±83 ml) (p=0.004). The decrease of BC was higher with previous MUI (184±92 ml vs 123±36 ml) versus no MUI (240±91 ml vs 237±78 ml), and the DH was more frequent in previous MUI and DH. There was a significant decrease of maximum flow rate (Qmax) (p=0.000) (although without clinical manifestation), and post void residual urine (p=0.007). We demonstrated a significant increase (p=0.001) of mean urethral resistance (URA): 12±9 cm H2O versus 15±12 cm H2O (without reaching obstruction range), and an improvement of detrusor contractility (W80-20): (3±4 W/m2; vs 6±17 W/m2;). CONCLUSION: We demonstrated worst results in MUI in patients with urinary incontinence undergoing SS. The urodynamic study gives a better prognosis reliability in the treatment of female urinary incontinence with SS.
