Ureteral Stenosis and Fistula after Kidney Transplantation.

INTRODUCTION: Ureteral complications after kidney transplantation are frequent and may have a negative impact on morbidity and graft function. Treatment modalities include conservative, endourological, and surgical techniques, with variable outcomes. The purpose of this study was to report the incidence, characteristics, treatment, and outcomes of ureteral complications at our center. METHODS: Retrospective study of kidney transplants performed at our unit between 2015 and 2020, analyzing incidence, characteristics, treatment, and outcomes of ureteral stenoses and fistulas. RESULTS: Of 648 kidney transplants, we present 3.24% stenosis and 2.16% ureteral fistulas, with a mean time from transplantation of 101.4 and 24.4 days, respectively. Primary treatment was open surgical repair in 52.4% stenosis and 100% fistulas, with a success rate of 90.9% and 71.4%, respectively. Anterograde balloon dilatations were performed in 33.3% of stenosis with 40% success. Three patients required surgery as a secondary approach with 100% success. Major complications (Clavien-Dindo III) were observed in 18.5% following surgical repair. After a mean follow-up of 31.1 ± 20.9 months, we observe 88.6% of functioning grafts. We found no significant differences in graft survival between patients with or without ureteral complications (p 0.948). CONCLUSION: Surgical repair of ureteral complications offers satisfactory results with low associated morbidity. Endourological techniques are less effective and should be reserved for selected cases. With adequate management, there is no impact on graft survival.

Validation of the Spanish Acute Cystitis Symptoms Score (ACSS) in native Spanish-speaking women of Europe and Latin America.

INTRODUCTION AND OBJECTIVES: The Acute Cystitis Symptom Score (ACSS) is a patient self-reporting questionnaire for clinical diagnostics and patient-reported outcome (PRO), which may assess the symptoms and the effect on the quality of life in women with acute cystitis (AC). The current study aimed to create a validated Spanish version of the ACSS questionnaire. MATERIAL AND METHODS: The process of linguistic validation of the Spanish version of the ACSS consisted of the independent forward and backward translations, revision and reconciliation, and cognitive assessment. Clinical evaluation of the study version of the ACSS was carried out in clinics in Spain and Latin America. Statistical tests included the calculation of Cronbach's α, split-half reliability, specificity, sensitivity, diagnostic odds ratio, positive and negative likelihood ratio, and area under the receiver-operating characteristic curve (AUC). RESULTS: The study was performed on 132 patients [age (mean;SD) 45.0;17.8 years] with AC and 55 controls (44.5;12.2 years). Cronbach's α of the ACSS was 0.86, and the split-half reliability was 0.82. The summary scores of the ACSS domains were significantly higher in patients than in controls, 16.0 and 2.0 (p < 0.001), respectively. The predefined cut-off point of ≥6 for a summary score of the "Typical" domain resulted in a specificity of 83.6% and a sensitivity of 99.2% for the Spanish version of the ACSS. AUC was 0.91 [0.85; 0.97]. CONCLUSIONS: The validated Spanish ACSS questionnaire evaluates the symptoms and clinical outcomes of patients with AC. It can be used as a patient's self-diagnosis of AC, as a PRO measure tool, and help to rule out other pathologies in patients with voiding syndrome.

[Penile prosthesis implantation in the covid era. post-surgery follow up and management of complications]. / Implante de prótesis de pene en la era COVID. Seguimiento tras la cirugía y manejo de complicaciones.

OBJECTIVES: To provide recommendations regarding surgery, follow-up, and management of possible complications related to penile prostheses implantation, during the COVID-19 pandemic. MATERIAL AND METHODS: We designed a critical narrative review of the studies investigating the impact of COVID-19 on urology practice and on penile prosthetic implantology. A comprehensive search in the MEDLINE database was performed. Different combinations of the following keywords were used according to a free-text protocol:: "SARS-CoV-2", "COVID19", "COVID Urology", "COVID19 surgery", "penile prostheses". Papers in English and Spanish language, published until September 2020 were included in the review. RESULTS: Penile prosthesis implantation is an elective surgery which should always be deferred when it cannot be performed in maximum safety conditions. However, it may lead to complications wich must be resolved urgently even within the COVID-19 Era. CONCLUSIONS: Currently, it is mandatory to develop shared strategies to avoid potential COVID-19-related complications for surgical patients. Penile prosthesis implantation should be deferred to avoid unnecessary risks and all preventive measures should be taken to minimize the risks in the event of non-delayable surgery.

Perinatal mesenchymal stromal cells of the human decidua restore continence in rats with stress urinary incontinence induced by simulated birth trauma and regulate senescence of fibroblasts from women with stress urinary incontinence.

Stress urinary incontinence (SUI) is a condition that causes the involuntary loss of urine when making small efforts, which seriously affects daily life of people who suffer from it. Women are more affected by this form of incontinence than men, since parity is the main risk factor. Weakening of the pelvic floor tissues is the cause of SUI, although a complete understanding of the cellular and molecular mechanisms of the pathology is still lacking. Reconstructive surgery to strengthen tissue in SUI patients is often associated with complications and/or is ineffective. Mesenchymal stromal cells from the maternal side of the placenta, i.e. the decidua, are proposed here as a therapeutic alternative based on the regenerative potential of mesenchymal cells. The animal model of SUI due to vaginal distention simulating labor has been used, and decidual mesenchymal stromal cell (DMSC) transplantation was effective in preventing a drop in pressure at the leak point in treated animals. Histological analysis of the urethras from DMSC-treated animals after VD showed recovery of the muscle fiber integrity, low or no extracellular matrix (ECM) infiltration and larger elastic fibers near the external urethral sphincter, compared to control animals. Cells isolated from the suburethral connective tissue of SUI patients were characterized as myofibroblasts, based on the expression of several specific genes and proteins, and were shown to achieve premature replicative senescence. Co-culture of SUI myofibroblasts with DMSC via transwell revealed a paracrine interaction between the cells through signals that mediated DMSC migration, SUI myofibroblast proliferation, and modulation of the proinflammatory and ECM-degrading milieu that is characteristic of senescence. In conclusion, DMSC could be an alternative therapeutic option for SUI by counteracting the effects of senescence in damaged pelvic tissue.

Efficacy and tolerability of the hexanic extract of Serenoa repens compared to tamsulosin in moderate-severe LUTS-BPH patients.

In a subset analysis of data from a 6-month, multicenter, non-interventional study, we compared change in symptoms and quality of life (QoL), and treatment tolerability, in men with moderate to severe lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) receiving tamsulosin (TAM, 0.4 mg/day) or the hexanic extract of Serenoa repens (HESr, 320 mg/day) as monotherapy. Symptoms and QoL were assessed using the IPSS and BII questionnaires, respectively. Patients in the treatment groups were matched using two statistical approaches (iterative and propensity score matching). Within the iterative matching approach, data was available from a total of 737 patients (353 TAM, 384 HESr). After 6 months, IPSS scores improved by a mean (SD) of 5.0 (4.3) points in the TAM group and 4.5 (4.7) points in the HESr group (p = 0.117, not significant). Improvements in QoL were equivalent in the two groups. TAM patients reported significantly more adverse effects than HESr patients (14.7% vs 2.1%; p < 0.001), particularly ejaculation dysfunction and orthostatic hypotension. These results show that HESr is a valid treatment option for men with moderate/severe LUTS/BPH; improvements in urinary symptoms and QoL were similar to those observed for tamsulosin, but with considerably fewer adverse effects.

Therapeutic concentrations of varenicline increases exocytotic release of catecholamines from human and rat adrenal chromaffin cells in the presence of nicotine.

Cardiovascular side effects of varenicline and a case report of a hypertensive crisis in a varenicline-prescribed patient with pheochromocytoma have been reported. The goal of the present study was to determine whether such side effects might derive, in part, from increased exocytosis of secretory vesicles and subsequent catecholamine release triggered by varenicline in human chromaffin cells of the adrenal gland. In this study, we performed electrophysiological plasma membrane capacitance and carbon fiber amperometry experiments to evaluate the effect of varenicline on exocytosis and catecholamine release, respectively, at concentrations reached during varenicline therapy (100 nM). Experiments were conducted in the absence or presence of nicotine, at plasma concentrations achieved right after smoking (250 nM) or steady-state concentrations (110 nM), in chromaffin cells of the adrenal gland obtained from human organ donors. Cells were stimulated with short pulses (10 ms) of acetylcholine (ACh; 300 µM) applied at 0.2 Hz, in order to closer mimic the physiological situation at the splanchnic nerve-chromaffin cell synapse. In addition, rat chromaffin cells were used to compare the effects obtained in cells from a more readily available species. Varenicline increased the exocytosis of secretory vesicles in human and rat chromaffin cells in the presence of nicotine, effects that were not due to an increase of plasma membrane capacitance or currents triggered by the nicotinic agonists alone. These results should be considered in nicotine addiction therapies when varenicline is used.

Iterative renal transplantation: our experience on third transplants.

PURPOSE: To report our experience on third kidney transplantation, analyzing the complications and graft survival rates as compared to previous transplants. METHODS: Retrospective study of third renal transplants performed at our center. Outcomes were compared with a cohort of first and second transplants. RESULTS: Of a total of 4143, we performed 72 third transplants in 46 men and 26 women with an average age of 46 years and mean time on dialysis of 70 months. Thirty-seven patients were hypersensitized [panel-reactive antibody (PRA) > 50%]. They were all from deceased donors, with a mean cold ischemia time of 19.2 h. The extraperitoneal heterotopic approach was used in 88.8%, transplantectomy was performed in 80.6% and vascular anastomoses were realized mostly to external iliac vessels, using the common iliac artery in 15 cases, and the inferior vena cava in 16. The main ureteral reimplantation technique was the Politano-Leadbetter (76.4%). Third transplantation reported a significantly higher incidence of lymphocele (13.9% vs. 3.2% in first and 4.5% in second transplants; p < 0.001), rejection (34.7% vs. 14.9% and 20.5%, p < 0.001) and urinary obstruction (11.1% vs. 3.6% and 6.3%, p 0.002). Graft survival rates for first, second and third transplants were 87%, 86% and 78% at 1 year, 83%, 82% and 74% at 3 years and 80%, 79% and 65% at 5 years, respectively. CONCLUSION: Iterative transplantation constitutes a valid therapeutic option with adequate surgical and survival results compared to previous transplants. It is a challenging procedure which must be performed by experienced surgeons.

The negative aftermath of prostate biopsy: prophylaxis, complications and antimicrobial stewardship: results of the global prevalence study of infections in urology 2010-2019.

PURPOSE: To evaluate and report the complications, and to analyse antimicrobial stewardship aspects following prostate biopsies (P-Bx) based on the data from a 9-year global study. METHODS: The primary outcome was to compare complications after P-Bx between patients of two cohorts: 2010-2014 and 2016-2019. Primary outcomes included symptoms of lower and severe/systemic urinary tract infection (LUTIS and SUTIS, respectively), and positive urine culture. Readmission to hospital after P-Bx, need for additional antimicrobial therapy, consumption of different antimicrobial agents for prophylaxis and therapy were evaluated. Students t test and chi-square test were used for comparative analyses. RESULTS: Outcome data were available for 1615 men. Fluoroquinolones-based prophylaxis rate increased from 72.0% in 2010-2014 to 78.6% in 2015-2019. Overall rates of complications increased from 6 to 11.7% including an increase in symptomatic complications from 4.7 to 10.2%, mainly due to an increase in LUTIS. Rates of patients seeking additional medical help in primary care after P-Bx increased from 7.4 to 14.4%; cases requiring post P-Bx antibiotic treatment increased from 6.1 to 9.7%, most of which received fluoroquinolones. Transperineal P-Bx was significantly associated with LUTIS. Following transrectal P-Bx, 2.8% developed febrile infections and 4.0% required hospitalisation. Two men (0.12%) died after transrectal P-Bx due to sepsis. CONCLUSIONS: The rates of complications after P-Bx tended to increase in time, as well as rates of patients seeking additional medical help in the post-P-Bx period. To reduce the risk of infectious complications and to comply with the principles of antibiotic stewardship, clinicians should switch to the transperineal biopsy route.

Role of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios in Peyronie's disease: a new diagnostic approach to predict the stage of the disease?

Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been associated with multiple entities and several types of cancers. They can be assumed as markers of inflammatory imbalance. The objective of this study is to evaluate the NLR and PLR in Peyronie's disease (PD) and to establish a comparison of its values in the acute and chronic stages. We recruited patients with PD from March 2018 to March 2019. The patients enrolled underwent medical and sexual history as well as a physical examination. The values of blood count of each patient were collected both in the acute and chronic stages. Wilcoxon test was used to compare the acute and chronic stage ratios. Kruskal-Wallis test was carried out to evaluate the impact of treatments on the ratios. To identify cutoff values, we used sensibility and specificity tables and receiver operating characteristic (ROC) curves. A total of 120 patients were enrolled. Their mean age was 55.85 (range: 18-77) years and the mean penile curvature was 48.43° (range: 10°-100°). In the acute stage, the mean NLR was 2.35 and the mean PLR was 111.22. These ratios, in the chronic stage, were 1.57 and 100.00, respectively. Statistically significant differences between acute and stable stages for both indices were found (NLR: P< 0.0001; PLR: P= 0.0202). The optimal cutoff for classification in acute or stable stage was 2 for NLR and 102 for PLR. According to our results, with an ordinary blood count, we could have important indications regarding the disease stage of the patient, and consequently on the most appropriate type of therapy to choose.

Treatment of peyronie's disease with combination of clostridium histolyticum collagenase and penile traction therapy: a prospective, multicenter, single-arm study.

The aim of this paper is to analyze our experience with intraplaque administration of collagenase from Clostridium Histolyticum (CCH) together with penile modeling for selected patients with Peyronie's disease (PD). We conducted a prospective, multicenter, single-arm study. Patients were included from October 2015 to August 2019. We carried out the I + E PROTOCOL (IMPRESS + extender). Each cycle involved administration of two injections of CCH separated 24-72 h, up to a maximum of four cycles. 24-48 h after injection patients underwent penile modeling maneuvers with the use of a PTD at home for at least 4 h a day. After each cycle, penile curvature was evaluated by the Kelami test. Mean pretreatment curvature was 57° (30-100). Eighty-seven patients underwent at least a single cycle and were eligible for analysis. Mean number of cycles administered was 2. Final average curvature after treatment, regardless of the number of cycles was 34°, with a mean reduction in curvature of -23.29° (-41%). Across the first three cycles we found statistically significant differences in the means in terms of the degrees of curvature after each cycle (p < 0.05), however this was not maintained in the fourth cycle. Statistical significance was also found when comparing the initial and final curvature after the complete treatment. We can conclude that treatment with CCH for PD is safe and effective. The concomitant use of CCH and PTT may limit the number of treatment cycles necessary to optimize outcomes when compared with CCH alone.

Efficacy and safety of dorsal penile nerve block before collagenase of clostridium histolyticum injections in peyronie's disease patients: Results from a prospective pilot study.

The intraplaque injection of collagenase from Clostridium Histolyticum (CCH) was established as an effective therapeutic alternative for selected patients with Peyronie's disease (PD). There is no consensus on the use of pre-procedure anaesthesia. The aim of this pilot study was to assess the efficacy and safety of dorsal penile block before CCH injections in reducing procedure related pain. The treatment protocol described in the IMPRESS trials was adopted. The first injection of the first cycle was given without anaesthesia, while the second after penile block. After the administration of each injection, the pain related to the procedure was evaluated with the Wong-Baker-FACES® -Pain-Rating-Scale. Thirty patients were included. Mean age 56.7 (SD: 9.61) years. Mean basal penile curvature 59.37º (SD: 18.26). The mean pain value related to the procedure measured after the first injection of the first cycle (without anaesthesia) was 5.4 (SD: 2.13), while after the second injection (with anaesthesia) was 2.5 (SD: 1.92), (p < .001). The treatment was more painful in patients with dorsal plaques (mean:6.2) than in patients with lateral plaques (mean: 4.35) (p = .01). We can conclude that penile block before CCH injection in patients with PD seems an effective and safe measure to decrease the pain related to the procedure.

A retrospective analysis comparing persistence and adherence to treatment with free- vs fixed-dose combination of an alpha blocker and an antimuscarinic agent in men with LUTS in Spain.

INTRODUCTION: Combination therapy with an alpha blocker (AB) plus an antimuscarinic (AM) is recommended for men with moderate-to-severe mixed lower urinary tract symptoms (LUTS) when monotherapy is not effective in relieving storage symptoms. This study compared treatment persistence and adherence with an AB plus AM fixed-dose combination (FDC) vs an AB plus AM free-dose combination in men with LUTS in Spain. METHODS: Retrospective study using the Spanish IQVIA Cegedim Electronic Medical Records database. Men prescribed AB plus AM combination therapy were included in an FDC or free-dose combination cohort based on their index treatment. Treatment persistence was the time from index date to first discontinuation of ≥1 of the two index drugs over 12 months. Adherence was measured using the fixed medication possession ratio (MPR). RESULTS: Of 3114 patients identified, 999 were included (FDC, n = 790; free-dose combination, n = 209). Median (95% CI) persistence was longer in the FDC (125 [109-151] days) than in the free-dose combination (31 [31-36] days) cohort (hazard ratio [HR], 2.9; 95% CI, 2.4-3.4; P < .0001). The 12-month persistence rates were 31.1% (FDC cohort) and 8.9% (free-dose cohort). The mean (SD) fixed MPR was higher in the FDC cohort (48.8 [37.2]) compared with the free-dose cohort (23.1 [28.4]); more patients in the FDC cohort (34.2%) than in the free-dose cohort (10.0%) were adherent (MPR ≥ 80%). The probability of treatment persistence and adherence increased with age (>80 vs <65 years, persistence HR, 0.7 [95% CI, 0.5-0.9]; MPR difference, 12.5), polypharmacy (persistence HR, 0.7 [95% CI, 0.6-0.9]; MPR difference, 10.7) and previous use of AB (persistence HR, 0.8 [95% CI, 0.7-1.0]; MPR difference, 5.7) or AB/AM combinations (persistence HR, 0.7 [95% CI, 0.5-0.9]; MPR difference, 11.1). CONCLUSIONS: Treatment with an AB/AM FDC is associated with better persistence and adherence vs a free-dose combination in men with LUTS in Spain.

[Benign prostatic hyperplasia management during COVID-19 pandemia.] / Manejo de la hiperplasia benigna de próstata durante la pandemia COVID-19.

OBJECTIVES: The pandemic caused by the new SARS / Cov-2 Coronavirus represents an unprecedented scenario in modern medicine that affects many aspects of daily healthcare. Lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) has a high prevalence and is related to high consumption of health resources. For this reason, we performed a revision of the management of LUTS and HBP during and after COVID-19 pandemic. MATERIAL AND METHODS: A group of experts in benign prostatic hyperplasia from different regions of Spain were selected to design a strategy to reorganize the management of benign prostatic hyperplasia and lower urinary tract symptoms during the pandemic. A comprehensive review of the literature was undertaken and a set of recommendations are generated. RESULTS: Recommendations for the management of LUTS-BPH during and after the SARS/CoV2 coronavirus pandemic outbreak consist of promoting telemedicine and developing joint protocols with Primary Care Attention .Clear diagnostic and treatment criteria and referral criteria must be established. Referral of patients for risk complications such as kidney failure, recurrent hematuria and obstructive uropathy are a priority. Surgeries due to BPH are generally potentially delayed until phases I and II of the pandemic, in which the percentage of hospitalized patients with COVID-19 does not exceed 25%, and it is necessary to determine COVID19 negativity. The surgical technique that associates the least complications and the shortest stay should be selected. CONCLUSIONS: The diagnosis and prescription of treatment for BPH during the COVID-19 pandemic should be based on telemedicine and joint protocols for primary care attention and urology. Elective surgical treatment can be delayed until we are in phases I or II, individualizing the surgical and anaesthetic technique of choice to minimize risks.

OBJETIVOS: La pandemia causada por el nuevo Coronavirus SARS/Cov-2 supone un escenario sin precedentes en la medicina moderna que afecta de manera indirecta en numerosos aspectos de nuestra actividad diaria como sanitarios. La hiperplasia benigna de próstata (HBP) es una patología con una elevada prevalencia y consumo de recursos sanitarios. Por ello, es necesaria una revisión en el manejo de la misma con el fin de adecuarlo a las necesidades impuestas por los acontecimientos recientes.MATERIAL Y MÉTODOS: Un grupo de expertos en hiperplasia benigna de próstata de distintas comunidades autónomas de España fueron contactados para diseñar una estrategia para reorganizar el manejo de la hiperplasia benigna de próstata y los síntomas del tracto urinario inferior durante la pandemia. Se realiza una revisión narrativa de la literatura publicada y se generan una serie de recomendaciones de manejo. RESULTADOS: Entre las recomendaciones para el manejo de HBP en tiempos de pandemia por coronavirus SARS/CoV2 se incluyen la promoción de teleconsulta y la realización de protocolos conjuntos con Atención Primaria estableciendo criterios de diagnóstico, tratamiento y derivación claros y homogéneos. Deben priorizarse las derivaciones pacientes complicaciones de riesgo tales como insuficiencia renal, hematuria recidivante y uropatía obstructiva. Desde el punto de vista quirúrgico, se trata generalmente de cirugías potencialmente demorables hasta fases I y II de la pandemia, donde el porcentaje de pacientes hospitalizados con Covid-19 no supera el 25%, siendo preciso determinar negatividad de COVID19. Debe seleccionarse la técnica quirúrgica que asocie una menor tasa de complicaciones así como una estancia más baja. CONCLUSIONES: El diagnóstico y el inicio del tratamiento médico de la HBP durante la pandemia debe basarse en la instauración de la telemedicina y protocolos conjuntos con atención primaria y urología. El tratamiento quirúrgico electivo se puede demorar hasta encontrarnos en fases I o II, individualizando la técnica quirúrgica y anestésica de elección para minimizar riesgos.

Physical exam in the evaluation of bladder pain syndrome (BPS): A key component for differential diagnosis. / La exploración física en la evaluación del síndrome de dolor vesical (SDV): un importante elemento para la orientación terapéutica.

OBJECTIVES: To describe in more detail the usual clinical practice regarding physical examination (PE) in Bladder Pain Syndrome (BPS) and to evaluate if the performance of PE relates to changes in severity of symptoms and in Health Related Quality of Life (HRQoL). MATERIAL AND METHODS: Epidemiological, observational, national and multicentric study that included 319 patients with BPS (79 of new diagnosis and 240 in follow-up). Demographic and clinical data were collected. The diagnostic study was performed according to the usual clinical practice, including as the case: PE and biopsy. The patients completed the "Bladder Pain/Interstitial Cystitis Symptom Score" (BPIC-SS) and "EuroQoL-5D-5L" (EQ-5D-5L) questionnaires. To describe the continuous variables, the mean, standard deviation (SD) and quartiles analyzed were used, and for categorical variables, number and percentage of patients by response category. The questionnaires' results were described according to the visual analog scale (VAS). Health status was evaluated in patients with myofascial pain. RESULTS: PE was performed in 296 cases. 28.4% of the patients presented pelvic myofascial pain. The variation of the BPIC-SS score in the explored patients was 7.77 points, compared to 1.73 in the unexplored ones. The variations in EQ-5D-5L were 0.13 and 0.04 points, respectively. CONCLUSIONS: Myofascial involvement was observed in 28.4% of the 296 cases of BPS who receiveda PE. It is important to implement a systematic, comprehensive method of PE at the national level in order to achieve a more precise characterization of BPS and a better evolution of the patient's symptoms and HRQoL.

Se recogieron datos demográficos y clínicos. El estudio diagnóstico se realizó según práctica  clínica habitual, incluyendo según el caso: EF y biopsia. Las pacientes cumplimentaron los cuestionarios "BladderPain/Interstitial Cystitis-Symptom Score" (BPIC-SS) y "EuroQoL-5D-5L" (EQ-5D-5L). Para describir las variables continuas se utilizaron la media, desviación estándar (DE) y cuartiles analizados y para las cualitativas, el número y porcentaje de pacientes por categoría de respuesta. Los resultados de los cuestionarios se describieron según la escala visual analógica (EVA). Se evaluó el estado de salud en pacientes con dolor miofascial. RESULTADOS: Se realizó EF en 296 casos. El 28,4% de los pacientes presentaban dolor miofascial. La variación de la puntuación BPIC-SS en los pacientes explorados fue de 7,77 puntos, en comparación con los 1,73 en los no explorados. Las variaciones en EQ-5D-5L fueron 0,13 y 0,04 puntos, respectivamente. CONCLUSIONES: La implicación miofascial se observó en el 28,4% de los 296 casos de SDV sometidos a EF. Es importante implementar un método sistemático e integral de EF a nivel nacional para lograr una caracterización más precisa del SDV y una mejor evolución de los síntomas y CVRS del paciente.

The challenge of pseudomonas aeruginosa related infections in a Urology Ward: Epidemiology, risk factors and patterns of antibiotic resistance. / El reto de las infecciones por pseudomonas aeruginosa en un Servicio de Urología: epidemiología, factores de riesgo y patrones de resistencia a antibióticos.

OBJECTIVES: Urological patients usually come up with risk factors for developing infections. Some of these are caused by multidrug-resistant microorganisms like Pseudomonas aeruginosa, whose notable resistance rates to antibiotics and aggressiveness make its treatment a challenge in clinical practice. Our objective was to analyze Pseudomonas aeruginosa infections incidence, risk factors and features in patients admitted to a Urology Ward in a tertiary care university hospital in Spain. MATERIAL AND METHODS: We carried out a prospective observational study from 2012 to 2017, to review all infections in our Ward with a special focus on those caused by Pseudomonas aeruginosa, performing a descriptive analysis and a comparison with other causative agents. RESULTS: 78 Infections with Pseudomonas aeruginosa isolation were registered during this period. Having a catheter of the upper urinary tract (CUUT) or comorbidities and undergoing surgery, were frequently observed among these patients although the results did not reach statistically significant differences for more frequent isolation compared to other pathogens. Antibiotic resistance rates were high for cephalosporins (33.3%) and quinolones (50%), while carbapenems (24.4%), aztreonam (10.3%) and amikacin (23.1%) exhibited the best activity. No deaths related to the infection were registered. CONCLUSIONS: Pseudomonas aeruginosa is commonly isolated in patients carrying a CUUT. An early suspicion of Pseudomonas aeruginosa infection and knowledge of local antibiotic resistance pattern are of paramount importance for improving the outcomes and handling this worldwide problem.

OBJETIVOS: Los pacientes urológicos se acompañan habitualmente de factores de riesgo para el desarrollo de infecciones. Algunas de éstas son causadas por microorganismos multi-resistentes como Pseudomonas aeruginosa, cuyas notables tasas de resistencia a los antibióticos y agresividad hacen de su tratamiento un reto para la práctica clínica. Nuestro objetivo fue analizar la incidencia de infecciones por Pseudomonas aeruginosa, factores de riesgo y características en pacientes ingresados en el Servicio de Urología de un hospital universitario de tercer nivel en España.MATERIALES Y MÉTODOS: Llevamos a cabo un estudio observacional prospectivo desde 2012 hasta 2017, para revisar todas las infecciones en nuestro Servicio, con especial atención en aquellas causadas por Pseudomonas aeruginosa, haciendo un análisis descriptivo y una comparación con otros agentes causales. RESULTADOS: Durante este periodo se registraron 78 infecciones por Pseudomonas aeruginosa. Frecuentemente estos pacientes portaban un catéter del tracto urinario superior, tenían comorbilidades o se habían sometido a una intervención quirúrgica, aunque ningún factor alcanzó la significación estadística para mayor frecuencia de aislamiento de Pseudomonas aeruginosa. Las tasas de resistencia antibiótica fueron altas para cefalosporinas (33,3%) y quinolonas (50%), mientras que los carbapenémicos (24,4%), aztreonam (10,3%) y amikacina (23,1%) mostraron la mejor actividad. No se registraron éxitus relacionados con estas infecciones. CONCLUSIONES: El aislamiento de Pseudomonas aeruginosa es frecuente en portadores de catéteres del tracto urinario superior. La sospecha precoz de estas infecciones y el conocimiento de los patrones locales de resistencia a antibióticos son de vital importancia para mejorar los resultados de este problema a nivel global.

Enhanced Contribution of Orai Channels to Contractility of Human Penile Smooth Muscle in Erectile Dysfunction.

BACKGROUND: Store-operated calcium entry and its key players, stromal interaction molecule (STIM) and Orai calcium channels, have been proposed as emergent therapeutic targets in cardiovascular pathophysiology. We hypothesize alteration of STIM/Orai signaling in erectile dysfunction (ED). AIM: To evaluate the contribution of STIM/Orai to human penile tissue contraction and to analyze the influence of ED on STIM/Orai signaling at functional and expression levels in human penile vascular tissues. METHODS: Human penile resistance arteries (HPRA) and human corpus cavernosum (HCC) were dissected from cavernosal specimens from 30 organ donors without history of ED (No ED) and from 48 patients with ED undergoing penile prosthesis insertion and functionally evaluated in wire myographs and organ chambers, respectively. Expression of STIM-1, Orai1, and Orai3 in HCC was localized and quantified by immunofluorescence. MAIN OUTCOME MEASURES: The main outcome measures are functional responses in HCC and HPRA and STIM/Orai channel protein expression in human cavernosal tissue. RESULTS: Inhibition of Orai channels with YM-58483 (20 µM) significantly reduced norepinephrine-induced contractions in both HCC and HPRA from either No ED or ED subjects, but the effects were more marked in ED (-20.1 ± 5.9% vs -45.5 ± 13.2% and -15.9 ± 4.0% vs -31.4 ± 6.9% reduction in Emax to norepinephrine in HCC and HPRA, respectively). Thromboxane-induced contractions were reduced and neurogenic contractile and relaxant responses modulated by Orai inhibition in penile tissues from patients with ED. In fact, addition of YM-58483 concentration dependently relaxed precontracted HPRA and HCC. These relaxations were significantly more pronounced in tissues from patients with ED (EC50 7.5 vs 1.3 µM and 10.5 vs 1.3 µM, for HCC and HPRA, respectively). All HCC specimens displayed expression of STIM-1, Orai1, and Orai3. Significantly increased expression of Orai1 and Orai3 but not STIM-1 was observed in patients with ED. CLINICAL TRANSLATION: Inhibition of enhanced Orai activity in human penile vascular tissue could facilitate erectile responses, alleviating ED. STRENGTHS AND LIMITATIONS: Enhanced STIM/Orai activity contribution to penile smooth muscle tone in ED is demonstrated at functional and structural levels in human tissues from a representative sample of patients with ED and in comparison with healthy tissue. We cannot differentiate the specific contribution of risk factors associated with ED to hyperactivity of the Orai system. CONCLUSIONS: Orai channels significantly contribute to human penile smooth muscle contraction. Orai contribution to penile smooth muscle tone is functionally enhanced in ED accompanied by increased expression of Orai channels in cavernosal tissue. Orai inhibition could be a potential therapeutic strategy to reduce penile smooth muscle contraction in ED. Sevilleja-Ortiz A, El Assar M, García-Rojo E, et al.

Consensus document on the multidisciplinary management of neurogenic lower urinary tract dysfunction in patients with multiple sclerosis.

AIM: Neurogenic lower urinary tract dysfunction (NLUTD) is very common in multiple sclerosis (MS) patients. Early diagnosis and treatment are crucial to avoid irreversible damage and improve quality of life. Our aim was to develop recommendations to improve NLUTD identification in MS patients, along with their referral and management. METHODS: A multidisciplinary group of 14 experts in the management of patients with MS and NLUTD (nine urologists, three neurologists, and two rehabilitators) was selected. A comprehensive review of the literature was undertaken and a set of recommendations was generated and submitted to a Delphi panel of 114 experts. Recommendations were presented according to the grade of agreement (GA). RESULTS: Early diagnosis in asymptomatic patients with risk factors for complications is recommended (GA 94%). Postvoid residual volume should be measured if changes in urinary symptoms (GA 87%), preferably ultrasound-guided (GA 86%). Early referral to urologist is recommended if urinary incontinence (GA 91%), significant post-void residual volume (94%), quality of life impairment (GA 98%) and recurrent urinary infections (GA 97%). The initial evaluation should include physical examination (GA 99%) and urodynamics including cystometry (GA 89%), pressure-flow study (90%) and electromyography (GA 70%). The panel recommends multidisciplinary collaboration (GA 100%) with a rehabilitation specialist and trained nurses in the management of NLUTD (GA 99%). CONCLUSIONS: Multidisciplinary management for patients with NLUTD due to MS is advised, including urologists, neurologists, rehabilitation, and nurses. Panel recommends early diagnosis with post-void residual volume in symptomatic patients before referring to urologist and urodynamics when referred.

Plication techniques in Peyronie's disease: new developments.

To date, surgical correction remains the gold standard for patients with stable Peyronie's disease (PD) due to its high efficacy and low morbidity. Among the surgical procedures, penile plication (PP) can be offered to men who have adequate erectile function and penile length (>13 cm), with a curvature <60° and a predicted shortening of maximum 20% of the penis. The aim of this paper is to review the new developments that have emerged in the last years about the use of PP in patients with PD. A nonsystematic review of the literature was carried out searching in the PubMed and EMBASE databases from January 01, 2009 to April 01, 2019 including the words 'Peyronie', 'penile curvature', 'penile induration', 'plication', and 'plicature'. New developments in PP in the last 10 years include avoiding degloving by using a penoscrotal incision, a new mathematical model to predict loss of length after PP, a wider range of indications including patients with severe (≥60°) or complex curvatures, burying knots to avoid later discomfort, and thinning or incising the plaque to prevent excessive shortening. PP is a well-founded procedure with great results in appropriately selected patients. Given the lack of any prospective randomized trial, no clear recommendation can be made of one technique over another.

The Brief Sexual Symptom Checklist as a Screening Tool for Sex-Related Problems in the Primary Care Setting: Focus on Erectile Dysfunction.

PURPOSE: To assess the performance of the Brief Sexual Symptom Checklist for men (BSSC-M) questionnaire in General Practitioner's (GP) consults in Spain. METHODS: Multicenter, cross-sectional study conducted in Spain among men ≥50 years, visiting a GP for any reason, and being able to answer self-administered questionnaires. Patients receiving medicines for erectile dysfunction (ED) and those with poor functional status were excluded. Sexual satisfaction was assessed by the BSSC-M, ED by the Sexual Health Inventory for Men (SHIM), and quality of life (QoL) using a 5-point Likert scale. RESULTS: In all, 770 men met all the selection criteria and 556 patients (72.2%) reported sexually related problems, ED being the most frequent (n = 427; 55.5%). The SHIM score decreased progressively with the number of causes of sexual dissatisfaction. Prevalence of ED (SHIM ≤21) was greater in patients who referred problems with erection in the BSSC-M questionnaire (76 vs. 14%; p < 0.001). Multivariate analysis for ED prediction revealed that sexual dissatisfaction, QoL (average or low/very low), and the presence of 3 or more comorbidities significantly influenced the chances of having ED. CONCLUSIONS: Our results encourage the use of the BSSC-M for identifying suspicion of ED and other sexual problems in patients > 50 who visit their GP for a routine follow-up.
