Development and validation of a clinical nomogram to predict prostatic inflammation in men with lower urinary tract symptoms.

BACKGROUND: Prostatic inflammation is an important etiological component of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). The Prostatic Inflammation Nomogram Study (PINS) aimed to develop and validate a nomogram for predicting the presence of prostatic inflammation in men with LUTS. METHODS: This non-interventional, cross-sectional, prospective study was conducted in six secondary/tertiary centers across Cyprus, Greece, Italy, Portugal, and Spain. Men (≥40 years) with BPH/LUTS scheduled to undergo prostatic surgery or transrectal ultrasound-guided (TRUS) prostate biopsy were included. Fifteen demographic and clinical participant characteristics were selected as possible predictors of prostatic inflammation. The presence of inflammation (according to Irani score) in the prostatic tissue samples obtained from surgery/TRUS biopsy was determined. The effect of each characteristic on the likelihood a prostate specimen demonstrated inflammation (classified by Irani score into two categories, 0-2 [no/minimal inflammation] or 3-6 [moderate/severe inflammation]) was assessed using multiple logistic regression. A nomogram was developed and its discriminatory ability and validity were assessed. RESULTS: In total, 423 patients (mean age 68.9 years) were recruited. Prostate volume ultrasound (PVUS) > 50 mL, history of urinary tract infection (UTI) treatment, presence of diabetes, and International Prostate Symptom Score (IPPS) Storage score were statistically significant predictors of Irani classification. Logistic regression demonstrated a statistically significant effect for leucocytes detected via urine dipstick, presence of diabetes, PVUS > 50 mL, history of UTIs, and higher IPSS Storage score for the odds of an inflammatory score category of 3-6 versus 0-2. The nomogram had a concordance index of 0.71, and good internal validity. CONCLUSIONS: The nomogram developed from PINS had good predictive ability and identified various characteristics to be predictors of prostatic inflammation. Use of the nomogram may aid in individualizing treatment for LUTS, by identifying individuals who are candidates for therapies targeting prostatic inflammation.

Analysis of prognostic factors of failure in perineal urethrostomy.

PURPOSE: To identify prognostic factors of failure in patients undergoing perineal urethrostomy (PU) with Blandy technique, with inverted U-shaped perineal flap. METHODS: This is a retrospective study of PU of non-oncological causes (2001-2017). Data of age, BMI, history of diabetes mellitus, etiology of urethral stricture, type of stricture, previous surgeries, dilatation and suprapubic catheter were collected. Failure was defined as the need for any instrumentation after surgery. Variables were analyzed by Cox regression and Kaplan-Meier curves were used for survival analysis. RESULTS: A total of 115 PU were performed. Median age was 61 years (IQR 53-68) and BMI 27.9 (IQR 25-30.9). The most frequent etiologies were: lichen sclerosus (30.4%), iatrogenic (27%), and idiopathic (25.7%). 62.6% had panurethral stricture. There were no complications in 73%. Clavien I complications occurred in 25.2%, Clavien II in 0.9% and Clavien IVa in 0.9%. The overall success rate was 51.3% with a median follow-up of 71 months. In the last 8 years, it was 75%. In the multivariate analysis, we found that age (p = 0.01), BMI (p = 0.01), date of surgery (p = 0.01), and suprapubic catheter (p = 0.003) were predictive variables. The voiding satisfaction rate was 88.7%. CONCLUSIONS: PU with Blandy technique is a surgery with low morbidity. During the entire study period, it had a failure rate of 48.7% but the failure rate decreased to 25% over the last 8 years. Age, BMI, date of surgery and suprapubic catheter are the most important prognostic factor of failure.

Mortality and biochemical recurrence after surgery, brachytherapy, or external radiotherapy for localized prostate cancer: a 10-year follow-up cohort study.

To compare the effectiveness at ten years of follow-up of radical prostatectomy, brachytherapy and external radiotherapy, in terms of overall survival, prostate cancer-specific mortality and biochemical recurrence. Cohort of men diagnosed with localized prostate cancer (T1/T2 and low/intermediate risk) from ten Spanish hospitals, followed for 10 years. The treatment selection was decided jointly by patients and physicians. Of 704 participants, 192 were treated with open radical retropubic prostatectomy, 317 with 125I brachytherapy alone, and 195 with 3D external beam radiation. We evaluated overall survival, prostate cancer-specific mortality, and biochemical recurrence. Kaplan-Meier estimators were plotted, and Cox proportional-hazards regression models were constructed to estimate hazard ratios (HR), adjusted by propensity scores. Of the 704 participants, 542 patients were alive ten years after treatment, and a total of 13 patients have been lost during follow-up. After adjusting by propensity score and Gleason score, brachytherapy and external radiotherapy were not associated with decreased 10-year overall survival (aHR = 1.36, p = 0.292 and aHR = 1.44, p = 0.222), but presented higher biochemical recurrence (aHR = 1.93, p = 0.004 and aHR = 2.56, p < 0.001) than radical prostatectomy at ten years of follow-up. Higher prostate cancer-specific mortality was also observed in external radiotherapy (aHR = 9.37, p = 0.015). Novel long-term results are provided on the effectiveness of brachytherapy to control localized prostate cancer ten years after treatment, compared to radical prostatectomy and external radiotherapy, presenting high overall survival, similarly to radical prostatectomy, but higher risk of biochemical progression. These findings provide valuable information to facilitate shared clinical decision-making.Study identifier at ClinicalTrials.gov: NCT01492751.

High ulcerative colitis and Crohn's disease ratio in a population-based registry from Córdoba, Argentina.

BACKGROUND: Few studies have described the epidemiology and clinical behavior of inflammatory bowel disease (IBD) in South America. The aim of this study was to report on the prevalence, phenotype, and treatment of patients with IBD diagnosis in Capital Department of the Province of Córdoba, Argentina. METHODS: Data from adult patients (≥ 18 years-old) with IBD diagnosis that attended 12 public or private centers between 05/2014 and 05/2019 were included in a common registry. RESULTS: A total of 655 patients were included (females: 53.4%). The ratio of ulcerative colitis (UC) (n = 561) to Crohn's disease (CD) (n = 88) was 6.38, with age-adjusted IBD prevalence being 70.1 (95% confidence interval 70.08-70.12) cases/100,000 habitants. Extraintestinal manifestations were diagnosed in 22.8% of patients, and left-side colitis (46%) was the most frequent extension in UC patients. In CD patients, colonic involvement (55.7%) and non-stricturing/non-penetrating behavior (74%) were the most frequent presentations. Biologic therapy was used in 36.4% of CD patients and 9.1% of UC patients (P<0.001). CONCLUSION: In this population registry study, IBD prevalence was similar to that reported in other series in the region. A higher UC/CD ratio was observed due to the lower prevalence of CD compared to similar studies in South America.

Comparative Effectiveness Research in Localized Prostate Cancer: A 10-Year Follow-up Cohort Study.

PURPOSE: Long-term comparative effectiveness research on localized prostate cancer treatments is scarce, and evidence is lacking especially for brachytherapy. The aim of this study was to assess the long-term impact of the side effects of radical prostatectomy, brachytherapy, and external radiation therapy on patients with localized prostate cancer at 10 years, using propensity score analyses. METHODS AND MATERIALS: This was a prospective observational study of a cohort of men who received a diagnosis of clinically localized prostate cancer (clinical stage T1 or T2, low and intermediate risk group) and were treated with radical prostatectomy (n = 139), brachytherapy (n = 317), or external radiation therapy (n = 194). Treatment decisions were jointly made by patients and physicians. Patient-reported outcome (PRO) evaluation included the Expanded Prostate Cancer Index Composite and Short Form-36, administered centrally by telephone interviews before and annually after treatment. The Expanded Prostate Cancer Index Composite covers urinary, bowel, sexual, and hormonal domains. To assess PRO changes over time, while accounting for correlation among repeated measures, generalized estimating equation models adjusted by propensity scores were constructed. RESULTS: The PRO completion rate at 10 years was 85.8%. Generalized estimating equation models showed that the pattern of radical prostatectomy side effects, with substantial urinary incontinence and sexual dysfunction, remained until 10 years after treatment (standard deviation [SD], -1.1 and -1.3, respectively). Brachytherapy produced late deterioration in urinary continence (SD, -0.4) and sexual function (SD, -0.9) that appeared midterm, but the differences from radical prostatectomy remained statistically significant at 10 years (P < .001 after adjusting by propensity score). External radiation therapy showed similar results to brachytherapy, but with bowel bother (SD, -0.3). CONCLUSIONS: Although late deterioration in radiation therapy groups attenuated differences from radical prostatectomy, relevant PRO differences still remained after 10 years. Our findings support that brachytherapy is the treatment option that causes the least impact on PROs; it is therefore an alternative to be considered when making evidence-based decisions on localized prostate cancer treatment.

Estimating preferences for treatments in patients with localized prostate cancer.

PURPOSE: Studies of patients' preferences for localized prostate cancer treatments have assessed radical prostatectomy and external radiation therapy, but none of them has evaluated brachytherapy. The aim of our study was to assess the preferences and willingness to pay of patients with localized prostate cancer who had been treated with radical prostatectomy, external radiation therapy, or brachytherapy, and their related urinary, sexual, and bowel side effects. METHODS AND MATERIALS: This was an observational, prospective cohort study with follow-up until 5 years after treatment. A total of 704 patients with low or intermediate risk localized prostate cancer were consecutively recruited from 2003 to 2005. The estimation of preferences was conducted using time trade-off, standard gamble, and willingness-to-pay methods. Side effects were measured with the Expanded Prostate Index Composite (EPIC), a prostate cancer-specific questionnaire. Tobit models were constructed to assess the impact of treatment and side effects on patients' preferences. Propensity score was applied to adjust for treatment selection bias. RESULTS: Of the 580 patients reporting preferences, 165 were treated with radical prostatectomy, 152 with external radiation therapy, and 263 with brachytherapy. Both time trade-off and standard gamble results indicated that the preferences of patients treated with brachytherapy were 0.06 utilities higher than those treated with radical prostatectomy (P=.01). Similarly, willingness-to-pay responses showed a difference of €57/month (P=.004) between these 2 treatments. Severe urinary incontinence presented an independent impact on the preferences elicited (P<.05), whereas no significant differences were found by bowel and sexual side effects. CONCLUSIONS: Our findings indicate that urinary incontinence is the side effect with the highest impact on preferences and that brachytherapy and external radiation therapy are more valued than radical prostatectomy. These time trade-off and standard gamble preference assessments as well as the willingness-to-pay estimation could be useful to perform respectively cost-utility or cost-benefit analyses, which can guide health policy decisions.

Quality of life impact of treatments for localized prostate cancer: cohort study with a 5 year follow-up.

PURPOSE: To assess long-term quality of life (QoL) impact of treatments in localized prostate cancer patients treated with radical prostatectomy, external beam radiotherapy or brachytherapy. MATERIAL AND METHODS: Observational, prospective cohort study with pre-treatment QoL evaluation and follow-up until five years after treatment. 704 patients with low or intermediate risk localized prostate cancer were consecutively recruited in 2003-2005. QoL was measured by the EPIC questionnaire, with urinary irritative-obstructive, incontinence, bowel, sexual, and hormonal scores (ranging 0-100). RESULTS: Brachytherapy's QoL impact was restricted to the urinary domain, Generalized Estimating Equation models showed score changes at five years of -12.0 (95% CI=-15.0, -9.0) in incontinence and -5.3 (95% CI=-7.5, -3.1) in irritative-obstructive scales. Compared to brachytherapy, radical prostatectomy fared +3.3 (95% CI=+0.0, +6.5) points better in irritative-obstructive but -17.1 (95% CI=-22.7, -11.5) worse in incontinence. Sexual deterioration was observed in radical prostatectomy (-19.1; 95% CI=-25.1, -13.1) and external radiotherapy groups (-7.5; 95% CI=-12.5, -2.5). CONCLUSIONS: Brachytherapy is the treatment causing the least impact on QoL except for moderate urinary irritative-obstructive symptoms. Our study provides novel long-term valuable information for clinical decision making, supporting brachytherapy as a possible alternative to radical prostatectomy for patients seeking an attempted curative treatment, while limiting the risk for urinary incontinence and sexual impact on QoL.

Quality-of-life impact of primary treatments for localized prostate cancer in patients without hormonal treatment.

PURPOSE: Earlier studies evaluating the effect on quality of life (QoL) of localized prostate cancer interventions included patients receiving adjuvant hormone therapy, which could have affected their outcomes. Our objective was to compare the QoL impact of the three most common primary treatments on patients who were not receiving adjuvant hormonal treatment. PATIENTS AND METHODS: This was a prospective study of 435 patients treated with radical prostatectomy, external-beam radiotherapy, or brachytherapy. QoL was assessed before and after treatment with the Short Form-36 and the Expanded Prostate Cancer Index Composite. Differences between groups were tested by analysis of variance. Distribution of outcome at 3 years was examined by stratifying according to baseline status. Generalized estimating equation models were constructed to assess the effect of treatment over time. RESULTS: Compared with the brachytherapy group, the prostatectomy group showed greater deterioration on urinary incontinence and sexual scores but better urinary irritative-obstructive results (-18.22, -13.19, and +6.38, respectively, at 3 years; P < .001). In patients with urinary irritative-obstructive symptoms at baseline, improvement was observed in 64% of those treated with nerve-sparing radical prostatectomy. Higher bowel worsening (-2.87, P = .04) was observed in the external radiotherapy group, with 20% of patients reporting bowel symptoms. CONCLUSION: Radical prostatectomy caused urinary incontinence and sexual dysfunction but improved pre-existing urinary irritative-obstructive symptoms. External radiotherapy and brachytherapy caused urinary irritative-obstructive adverse effects and some sexual dysfunction. External radiotherapy also caused bowel adverse effects. Relevant differences between treatment groups persisted for up to 3 years of follow-up, although the difference in sexual adverse effects between brachytherapy and prostatectomy tended to decline over long-term follow-up. These results provide valuable information for clinical decision making.

Laparoscopic kidney transplantation.

We present the details of the first laparoscopic transplantation of a kidney from a living, related donor, performed April 16, 2009. Surgical and functional results were acceptable. Surgical time was 240 min (53 min for vascular suture), with blood loss of 300 cm(3) and a hospital stay of 14 d. Serum creatinine at discharge was 73 mmol/l. Laparoscopic kidney transplantation is a complex technique that requires previous experience in vascular and laparoscopic surgery. As with all novel procedures, technical modifications will be required to formalize its use and detailed comparisons will need to be made with standard procedures.

[Evaluation of the quality of life of patients with localizad prostate cancer: validation of the Spanish version of the EPIC]. / Evaluación de la calidad de vida de los pacientes con cáncer de próstata localizado: validación de la versión española del cuestionario EPIC.

BACKGROUND AND OBJECTIVE: The EPIC (Expanded Prostate Cancer Index Composite) is a specific questionnaire for patients with prostate cancer designed to evaluate the impact of treatments on their quality of life. It contains 50 items divided in 4 summaries: urinary, intestinal, sexual and hormonal. The objective was to adapt the EPIC to Spanish and to evaluate its metric characteristics. METHOD: The method followed for the adaptation included translation and back-translation. The metric characteristics were evaluated in 50 patients from each treatment -prostatectomy, brachytherapy and external radiotherapy-, all of whom were administered the EPIC, SF-36 and FACT (Functional Assessment of Cancer Therapy) pre and post intervention. Reliability was evaluated with the Cronbach alpha coefficient. Construct validity was assessed by means of correlations between subscales of the EPIC and questionnaires, and comparing the patients with and without hormonal therapy (T-test). In order to value sensitivity to change, the standardized effect size was calculated after the intervention. RESULTS: The Cronbach's alpha of the EPIC summaries was high (0.66-0.89). The correlations between the EPIC and the FACT were near or higher than 0.4. Differences were found in the hormonal and sexual summaries between the patients with and without hormonal therapy (p<0.01). The standardized effect size was large (>0.8) in the urinary (3 groups) and sexual (group of prostatectomy) summary, and moderate in the intestinal summary (0.6 and 0.7) for the 2 groups of radiotherapy. CONCLUSIONS: The Spanish version of the EPIC is reliable, valid and presents an excellent sensitivity to change, being a useful tool to compare the impact in the quality of life of the 3 treatments.

Evaluación de la calidad de vida de los pacientes con cáncer de próstata localizado: validación de la versión española del cuestionario EPIC / Evaluation of the quality of life of patients with localizad prostate cancer: validation of the Spanish version of the EPIC

Fundamento y objetivo: el EPIC (Expanded Prostate Cancer Index Composite) es un cuestionario específico para la evaluación del impacto de los tratamientos en la calidad de vida de los pacientes con cáncer de próstata. Contiene 50 ítems divididos en 4 sumarios: urinario, intestinal, sexual y hormonal. El objetivo de este trabajo ha sido adaptar el cuestionario EPIC al español y evaluar sus características métricas. Método: para la adaptación se siguió el método de traducción directa-inversa. Las características métricas se evaluaron en 50 pacientes de cada tratamiento ¿prostatectomía, braquiterapia y radioterapia externa¿, a quienes se administraron el EPIC, SF-36 y FACT (Functional Assessment of Cancer Therapy) antes y después de la intervención. Con el coeficiente alfa de Cronbach se evaluó la fiabilidad. La validez de constructo se estudió mediante correlaciones entre subescalas del EPIC y entre cuestionarios, y comparando a los pacientes con y sin hormonoterapia (prueba de la t de Student). Para valorar la sensibilidad al cambio se calculó el tamaño del efecto estandarizado tras la intervención. Resultados: el alfa de Chronbach de los sumarios del EPIC fue elevado (0,66¿0,89). Las correlaciones entre el EPIC y el FACT fueron cercanas o superiores a 0,4. Se encontraron diferencias en los sumarios hormonal y sexual entre los pacientes con y sin hormonoterapia (p<0,01). El tamaño del efecto estandarizado fue grande (>0,8) en los sumarios urinario (3 grupos) y sexual (grupo de prostatectomía), y moderado en el sumario intestinal (0,6 y 0,7) para los 2 grupos de radioterapia. Conclusiones: la versión en castellano del EPIC es fiable y válida, y presenta una sensibilidad al cambio excelente, por lo que resulta una herramienta útil para comparar el impacto en la calidad de vida de los 3 tratamientos (AU)

Traumatismo renal con urinoma / Renal traumatism with urinoma

El extravasado de orina ocurre en los traumatismos renales que interesan la vía urinaria. El mecanismo de producción del traumatismo, la clínica y la exploración física permiten limitar el diagnóstico a la región lumbar o extenderlo a otras regiones, pero la determinación de la presencia de urinoma precisa de otros métodos. La TC es la mejor prueba diagnóstica aunque en la fase inicial del traumatismo puede no demostrar fuga de contraste. En aquellos casos en que el paciente está inestable, en las lesiones penetrantes o ante una lesión vascular sangrante, debe optarse por la técnica más resolutiva

The leak out of urine occurs in renal traumatisms that affect the urinary system. The mechanism of production of the traumatism, clinic and physical exploration allow to limit the diagnosis to the lumbar region or extended it to other regions, but the determination of the presence of urinoma requires other methods. CT is the best diagnostic test although in the initial phase of the traumatism may not show leakage of contrast. In the cases where the patient is unstable, or in cases of penetrating injuries or in a vascular bleeding injury, we should adopt a more resolutive technique
