RESUMEN
BACKGROUND: Tumor human leukocyte antigen class I (HLA-I) expression plays an important role in T cell-mediated tumor rejection. Loss of HLA-I is associated with cancer progression and resistance to immunotherapy, including antibodies blocking programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) signaling. Our objective was to analyze a correlation between HLA-I, tumor immune infiltration, and PD-L1/PD-1 axis in bladder cancer in association with the clinicopathologic features of patients. METHODS: We analyzed 85 cryopreserved bladder tumors by immunohistochemistry to investigate the expression of HLA-I, PD-L1, PD-1, CD3, CD8, and CXC chemokine receptor 4 (CXCR4). The results were correlated with tumor stage and other clinicopathologic variables of patients. RESULTS: We found a strong positive correlation between tumor HLA-I expression and infiltration with CD3+ and CD8 + T cells. PD-L1 expression was positive in 15.5% of tumors and heterogeneous in 40.5%, and was linked to a more advanced tumor stage. The majority of HLA-I-positive/heterogeneous tumors also expressed PD-L1 and PD-1, which were significantly correlated with each other and with lymphocyte infiltration. Interestingly, the analysis of the simultaneous expression of both markers revealed that 85.2% of tumors with a positive/heterogeneous HLA-I phenotype and negative for PD-L1 were mostly non-invasive, representing a 'tumor rejection' immune phenotype. CONCLUSIONS: High tumor HLA-I expression with absence of PD-L1 provides bladder cancer with an immune rejection mechanism. Evaluation of PD-L1 and HLA-I together should be considered in bladder cancer and may provide a new predictive biomarker of tumor invasiveness and of the response to 'immune checkpoint' therapy.

INTRODUCTION: The objective was to evaluate the effect of hydrochlorothiazide and alendronate on urine calcium and bone mineral density in calcium stone-forming patients. MATERIAL AND METHODS: A prospective, non-randomized, non-observational comparative study was performed; this study included 111 patients with recurrent calcium stones, divided into 3 groups according to the treatment received. Group 1: 36 patients were treated with alendronate, 70 mg/week; Group 2: 34 patients were treated with alendronate, 70 mg/week + hydrochlorothiazide, 50 mg/day; Group 3: 41 patients were treated with hydrochlorothiazide, 50 mg/day. All patients received recommendations on diet and fluid intake. Other variables of bone mineral density were studied and analyzed, including bone remodeling markers and urinary calcium before and after 2 years of treatment. The statistical analysis was performed using the SPSS 17.0 program, with a statistical significance of p < 0.05. RESULTS: After 2 years of treatment, a significant difference was observed in the ß-crosslaps and a bone mineral density improvement in Group 1, along with a decrease in urinary calcium. In Group 3, a statistically significant difference was found in urinary calcium and fasting calcium/creatinine ratio, as well as an improvement in bone mineral density after 2 years of medical treatment. In Group 2 patients treated with the combination, there was an improvement in bone mineral density and a decrease in the ß-crosslaps marker similar to patients in Group 1, and a decrease in urinary calcium similar to those in Group 3. CONCLUSION: Combined alendronate + hydrochlorothiazide treatment offers the best results along with the improvement in bone mineral density and decrease in urine calcium in patients with recurrent calcium stones.

AIMS: This study aims to describe the information needs of urological and breast cancer patients and factors related to use of the Internet as a source of health information. METHODOLOGY: A cross-sectional descriptive study was carried out, using individual questionnaire-based interviews held during the oncology appointments of 169 patients with urological cancer and 100 with breast cancer at the Virgen de las Nieves University Hospital in Granada, Spain. The variables studied were use of the Internet as a source of health information, health status, patient's role in the decision-making process, information sources, satisfaction with the health-care system, type of information received, and Internet use. A multivariate logistic regression analysis was carried out. RESULTS: Breast cancer patients are more concerned with long-term results and the effects on their family and personal life. They are also interested in the experiences of other patients and support groups or staff who could help them to cope with their illness. The information needs of patients with urological cancer are linked to short-term alternative treatments, their sex life, keeping healthy, and exercise. More clinical aspects, such as tests and experiments linked to their treatment, are not a frequent information need. The factors linked to use of the Internet as a source of health information are younger age, high level of education, the patient's active role in the decision-making process, and undergoing more aggressive treatment. There is no link between using the Internet as a source of health information and level of satisfaction with the health-care system, or with Internet use in general. CONCLUSION: Patients need additional information about their illness on top of that given to them by health-care staff, and they often use the Internet to find it. The greatest information need is related to the effects of their illness on their day-to-day life. Health-care staff should provide patients with advice about reliable websites and how to search the Internet.

INTRODUCTION: Mental disorders, smoking, or alcoholism and benign prostate disease are highly prevalent in men. AIMS: To identify the relationship between mental disorders, smoking, or alcoholism and benign prostate disease. METHODOLOGY: A prospective multicenter study that evaluated prostate health status in 558 men from the community. Groups: GP-men who request a prostate health examination and whose medical history includes a mental disorder, smoking, or alcoholism prior to a diagnosis of benign prostate disease; GU-men who request a prostate health examination and whose medical history includes a benign prostate disease prior to a diagnosis of mental disorder, smoking, or alcoholism. VARIABLES: age, body mass index (BMI), prostate specific antigen (PSA), follow-up of the mental disorder, smoking or alcoholism, time elapsed between urological diagnosis and the mental disorder, smoking or alcoholism diagnosis, status of the urological disease (cured or not cured), concomitant diseases, surgical history, and concomitant treatments. Descriptive statistics, Student's t-test, Chi2, multivariate analysis. RESULTS: There were no mental disorders, smoking, or alcoholism in 51.97% of men. Anxiety, smoking, major depressive disorder, pathological insomnia, psychosis, and alcoholism were identified in 19.71%, 13.26%, 5.73%, 4.30%, 2.87%, and 2.15% of individuals, respectively. Nonbacterial prostatitis (31.54%), urinary tract infection (other than prostatitis, 24.37%), prostatic intraepithelial neoplasia (13.98%), and prostatodynia (1.43%) were prostate diseases. Unresolved symptomatic benign prostate disease was associated with anxiety, depression, and psychosis (p = 0.002). Smoking was the disorder that men managed to eliminate most frequently. The dominant disorder in patients with symptomatic benign prostatic disease was alcoholism (p = 0.006). CONCLUSIONS: Unresolved symptomatic benign prostatic disease is associated with anxiety, depression, and psychosis. Alcoholism is associated with a worse prognosis in the follow-up of symptomatic benign prostatic disease.

BACKGROUND: People who use the Internet to research health topics do not usually find all the information they need and do not trust what they read. This study was designed to assess the reliability, accessibility, readability, and popularity of cancer Web sites in Spanish and to analyze the suitability of Web site content in accordance with the specific information needs of cancer patients. MATERIALS AND METHODS: This was a two-phase, cross-sectional, descriptive study. The first phase involved data gathering through online searches and direct observation. The second phase involved individual structured interviews with 169 patients with breast, prostate, bladder, and kidney cancer. Spearman rank correlations were calculated between variables. RESULTS: Most sites belonged to nonprofit organizations, followed by universities or medical centers (14%). Thirty-one percent of the Web sites had quality seals, 59% provided details of authorship, 62% provided references to bibliographic sources, 38% identified their funding sources, and 54% showed the date of their last update. Twenty-one percent of the Web sites did not meet the minimum accessibility criteria. With regard to readability, 24% of the texts were considered to be "quite difficult." Patients' information needs vary depending on the type of cancer they have, although all patients want to know about the likelihood of a cure, survival rates, the side effects, and risks of treatment. CONCLUSIONS: The health information on cancer available on the Internet in Spanish is not very reliable, accessible, or readable and is not necessarily the information that breast, kidney, prostate, and bladder cancer patients require. The content of cancer Web sites needs to be assessed according to the information needs of patients.

OBJECTIVES: To analize the current role of target therapies in the treatment of small renal masses. METHODS: We performed a bibliographic review on the effect of target therapies on primary renal tumor, including our initial experience with two cases of small renal tumor in single kidneys treated with sunitinib. RESULTS: There is very limited experience with target therapies, being possible to use them, as the reviewed literature shows, to increase safety in nephron sparing surgery or tissue ablation technique, or as the treatment for small renal tumors in patients with single kidney in whom nephron sparing surgery is not feasible. Of our two cases with small renal tumors in patients with single kidney, the first case has had complete response to sunitinib after 21 months of follow up, and the second has had tumor stabilization after 33 months of follow up, shifting from sunitinib to pazopanib due to intolerance. CONCLUSIONS: The indication of target therapies in the treatment of metastatic renal cancer could be expanded. These therapies could be useful in localized small renal cancer and, although experience with this indication is limited, results are promising.

AIMS: The aims of this study were to describe the profile of urological cancer patients who look for health information on the Internet and to analyse the factors related to use of the Internet as a source of health information. METHODOLOGY: A cross-sectional descriptive study using individual, semi-structured, questionnaire-based interviews was carried out in oncology clinics in a hospital in Granada (Spain) in a sample group of 169 patients with prostate, bladder and kidney cancer. The dependent variable was use of the Internet as a source of health information. The independent variables were sociodemographic variables, health status, relationship with healthcare services, patient's role in decision-making process, satisfaction with healthcare, Internet use, Internet skills and attitude. Data analyses include descriptive, bivariate and multivariate analyses. RESULTS: Of the patients in the sample group, 72.2 % had prostate cancer, 19.4 % had bladder cancer and 8.3 % had kidney cancer. Only 11.2 % of patients in the group used the Internet as a source of health information. These patients were typically men of an average age of 62 years, who live in urban areas, who have completed secondary or university education, with a high income and who usually share the role of decision maker with their doctor. Patients who use the Internet as a source of health information usually look for support from psychological support groups, have family members who also look for information on the Internet and prefer sources of information other than those provided by the health services. CONCLUSIONS: The study outlines the profile of urological cancer patients who use the Internet as a source of health information. Internet use is related to a patient's attitude towards decision making, level of education and whether or not they look for information from sources other than the health system itself.

In this study, we have evaluated whether 57 genome-wide association studies (GWAS)-identified common variants for type 2 diabetes (T2D) influence the risk of developing prostate cancer (PCa) in a population of 304 Caucasian PCa patients and 686 controls. The association of selected single nucleotide polymorphisms (SNPs) with the risk of PCa was validated through meta-analysis of our data with those from the UKBiobank and FinnGen cohorts, but also previously published genetic studies. We also evaluated whether T2D SNPs associated with PCa risk could influence host immune responses by analysing their correlation with absolute numbers of 91 blood-derived cell populations and circulating levels of 103 immunological proteins and 7 steroid hormones. We also investigated the correlation of the most interesting SNPs with cytokine levels after in vitro stimulation of whole blood, peripheral mononuclear cells (PBMCs), and monocyte-derived macrophages with LPS, PHA, Pam3Cys, and Staphylococcus Aureus. The meta-analysis of our data with those from six large cohorts confirmed that each copy of the FTOrs9939609A, HNF1Brs7501939T, HNF1Brs757210T, HNF1Brs4430796G, and JAZF1rs10486567A alleles significantly decreased risk of developing PCa (p = 3.70 × 10-5, p = 9.39 × 10-54, p = 5.04 × 10-54, p = 1.19 × 10-71, and p = 1.66 × 10-18, respectively). Although it was not statistically significant after correction for multiple testing, we also found that the NOTCH2rs10923931T and RBMS1rs7593730 SNPs associated with the risk of developing PCa (p = 8.49 × 10-4 and 0.004). Interestingly, we found that the protective effect attributed to the HFN1B locus could be mediated by the SULT1A1 protein (p = 0.00030), an arylsulfotransferase that catalyzes the sulfate conjugation of many hormones, neurotransmitters, drugs, and xenobiotic compounds. In addition to these results, eQTL analysis revealed that the HNF1Brs7501939, HNF1Brs757210, HNF1Brs4430796, NOTCH2rs10923931, and RBMS1rs7593730 SNPs influence the risk of PCa through the modulation of mRNA levels of their respective genes in whole blood and/or liver. These results confirm that functional TD2-related variants influence the risk of developing PCa, but also highlight the need of additional experiments to validate our functional results in a tumoral tissue context.

INTRODUCTION: The crisis in the SARSCoV-2 coronavirus causing COVID-19 is putting health systems around the world to the test. In a great effort to standardize the management and treatment guidelines, the different health authorities and scientific associations have tried to issue recommendations on how to act in this new and complex scenario. OBJECTIVE: To synthesize the existing evidence and recommendations about urological emergency surgery during the COVID-19 pandemic situation. Furthermore, we propose a general action protocol for these patients. MATERIAL AND METHODS: The document is based ont he scarce evidence on SARS / Cov-2 and the experience of the authors in the management of COVID-19 in their institutions, including specialists from Andalusia, Cantabria, Madrid and the Basque Country. A web and PubMed search was performed using the keywords "SARS-CoV-2", "COVID19", "COVID Urology", "COVID19 surgery" and "emergency care". A narrative review of the literature was carried out until April 30, 2020, including only articles and documents written in Spanish and English. After the nominal group technique modified due to the extraordinary restrictions, a first draft was made to unify criteria. Finally, a definitive version was made, agreed by all the authors on May 12, 2020. RESULTS: General principles of action are set out, as well as specific recommendations for the most frequent urgent urological procedures. CONCLUSIONS: Given the exceptional nature of the situation, there is a lack of evidence regarding the optimal management of the patient with urgent urological pathology. The information is changing, as the epidemiological knowledge of the disease advances. The establishment of multidisciplinary surgical committees that develop and implement action protocols appropriate to the different resources and particular situations of each center is recommended. Likewise, these committees must individually assess each possible urological surgical emergency situation and ensure compliance with protective measures for the patient and other healthcare personnel.

Finalmente, se realizó una versión definitiva, consensuada por todos los autores el 12 Mayo 2020. RESULTADOS: Se exponen unos principios generales de actuación, así como unas recomendaciones específicas para los procedimientos urológicos urgentes más frecuentes.CONCLUSIONES: Dado el carácter excepcional de la situación, existe un déficit de evidencia respecto al óptimo manejo del paciente con patología urológica urgente. La información es cambiante, según avanza el conocimiento epidemiológico de la enfermedad. Es recomendable el establecimiento de comités multidisciplinares quirúrgicos que desarrollen e implementen protocolos de actuación adecuados a los distintos recursos y situaciones particulares de cada centro. Del mismo modo, estos comités deben evaluar de forma individualizada cada posible situación de urgencia quirúrgica urológica y velar por el cumplimiento de las medidas de protección para el paciente y resto del personal sanitario.

Inflammation has been implicated as an etiological factor in different human cancers. Allelic variations in the genes implicated in inflammation are candidates as genetic determinants or markers of renal carcinoma risk. The present stud investigates whether polymorphisms of the genes that give rise to increases in the levels of proinflammatory cytokines and chemokines are associated with an increased risk of renal carcinoma. To this effect, a number of case-control studies were designed to assess the correlation between renal carcinoma and polymorphisms IL10-1082 A/G (rs 1800896), IL10-592 A/C (rs 1800872), IL10-819 C/T (rs 1800871), IL10-1082 A/G, IL4-590 C/T (rs 2243250), TNF-A-308 A/G (rs 1800629), RANTES-403 G/A (rs 2107538), IL1-A-889 C/T (rs 1800587), MCP-1 2518 G/A (rs 1024611), CTLA-4/+49 A/G (rs 231775) and CTLA-4 CT60 A/G (rs 3087243) in 127 renal carcinoma patients and in 176 healthy subjects. The results obtained in relation to cytokine polymorphism IL-10-1082 A/G indicate that AG heterozygosity status is the principal risk factor in relation to locally advanced or metastatic tumor stage and renal carcinoma. In the case of the molecule CTLA4, the results obtained in renal cancer reveal an association between the polymorphisms of the CTLA-4 gene and an increased risk of developing renal cell carcinoma. A high genotypic frequency of polymorphisms CTLA4/CT60-AA and CTLA4/A49G-AA is observed in patients with renal cell carcinoma versus the controls. An association has been established between polymorphism CTLA4/CT60 and tumor grade in patients with renal cell carcinoma. Logistic regression analysis has confirmed these data, demonstrating a high frequency of the AA genotype in patients with high-grade tumors. The results obtained support the hypothesis that different genetic factors implicated in the regulation of adaptive immune responses, stromal cell composition and local cytokine production levels may be crucial elements in the modification of the clinicopathological parameters of renal carcinoma.

OBJECTIVES: We report the cases of three patients with primary renal lymphoma. Diagnosis and subsequent treatment are discussed. METHODS: The literature on the origin, epidemiology, clinical presentation, diagnosis, treatment and prognosis of primary renal lymphoma was reviewed. RESULTS: The first patient was diagnosed after radical nephrectomy and subsequently was given six cycles of CVP (cyclophosphamide, vincristine, prednisone). The diagnosis of the second patient was established by renal biopsy, and the patient received six cycles of CHOP (cyclophosphamide, adriamycin, vincristine and predisone). The last patient had a lymphoma, secondary to immunosuppression, in a transplanted kidney. In this case transplant nephrectomy sufficed to cure the patient's lymphoma. All patients had B-cell non-Hodgkin lymphoma (an extrarenal origin was ruled out by bone marrow biopsy), and were disease-free 15 months, 7 months, and 6.5 years after diagnosis, respectively. CONCLUSIONS: Primary renal lymphoma is rare. Diagnosis is established by renal biopsy, although it often presents as a mass simulating renal cell cancer and diagnosis is obtained after radical nephrectomy. Treatment consists of chemotherapy (CHOP). associated with rituximab.

PURPOSE: To evaluate the efficacy of oral anticholinergics as a preventive strategy of storage symptoms and urinary incontinence associated with the early postoperative period after Greenlight laser photovaporization of the prostate (PVP). To analyze potential variables related to the onset of these symptoms. MATERIALS AND METHODS: Retrospective study of 105 patients who underwent PVP using a 180-W Greenlight laser (XPS). Patients were divided into two groups, depending on whether they were or weren´t prescribed anticholinergics when discharged (oral solifenacin 5 mg for 1 month after surgery). Differences between both groups were analyzed according to IPSS, ICIQ-SF and OABq-SF scores at 1 and 6 months. The potentially predictive variables of the symptomatology after undergoing PVP that we analyzed included age, prostate volume, PSA, IPSS, ICIQ-SF, OABq-SF, Qmax, previous use of a permanent urinary catheter, energy used, and laser application time. RESULTS: 58 patients in the group with anticholinergics and 47 in the group without anticholinergics were compared. No significant differences were observed between both groups in IPSS (p = .521), ICIQ-SF (p = .720) or OABq-SF (p = .851) at 1 and 6 months after surgery. Regardless of the use of anticholinergics, there was a significant score improvement between the first and second checkup in all the questionnaires: there was a significant decrease in the mean IPSS (p < .001) and the mean score of the eighth IPSS question on patient's quality of life (p = .026), ICIQ- SF (p = .010) and OAB-q related to symptoms (p = .001) as well as a significant increase in the mean OAB-q score regarding quality of life (p = .005). None of the variables analyzed showed a significant relation to the storage-symptom rate, rate of incontinence, or ICIQ-SF and OABq-SF scores. CONCLUSIONS: The use of solifenacin 5 mg after Greenlight laser PVP is not an effective preventive treatment for storage and incontinence symptoms associated with this procedure, which seem to self-limit over time.

OBJECTIVE: Following first-line treatment progression in metastatic renal carcinoma, different options for second-line treatment are available, with axitinib being one of them. The objective of this article is to evaluate the results of Axitinib in a real practice setting. METHODS: From December 2011 to October 2016, we treated 19 patients with CCRM with Axitinib, 3 patients in third line and 16 patients in second line after progression on Sunitinib or Pazopanib. We performed a retrospective study of the last 16 patients, analyzing the effectiveness and safety of the drug. RESULTS: The median progression-free survival (PFS) was 9 months and the median overall survival with 8 dead patients was 59 months. Overall, toxicity by Axitinib was very common, diarrhea 87.5%, asthenia 75%, dysphonia 56.25%, hypertension 37.5% and anorexia 37.5%, although most are grade 1-2 toxicities controlled with hygiene-diet measures and treatment recommendations. CONCLUSIONS: Axitinib is a drug that has been shown to increase PFS after 1st line progression, with a tolerable toxic profile. With the approval of nivolumab and cabozantinib, the place of Axitinib in sequential therapy is yet to be defined.
OBJETIVO: Tras progresión de primera línea de tratamiento en el carcinoma renal metastásico hay disponibles distintas opciones de tratamiento de segunda línea, siendo Axitinib una de ellas. MÉTODOS: Desde diciembre de 2011 hasta octubre de 2016, hemos tratado a 19 pacientes con CCRm con Axitinib, 3 pacientes en tercera línea y 16 en segunda línea tras progresión de Sunitinib o Pazopanib. Realizamos un estudio retrospectivo de los últimos 16 pacientes, analizando efectividad y seguridad del fármaco. RESULTADOS: La mediana de la supervivencia libre de progresión (SLP) fue de 9 meses y la mediana de supervivencia global con 8 pacientes fallecidos fue de 59 meses. La toxicidad global por Axitinib fue muy frecuente, diarrea 87,5%, astenia 75%, disfonía 56,25%, HTA 37,5% y anorexia 37,5%, aunque en su mayoría fueron toxicidades grado 1-2 controlados con medidas higiénico dietéticas y recomendaciones de tratamiento. CONCLUSIONES: Axitinib es un fármaco que ha demostrado aumentar la SLP tras progresión de 1ª línea, con un perfil toxico tolerable. Con la aprobación de nivolumab y cabozantinib, el lugar de Axitinib en la terapia secuencial está por definir.

PURPOSE: To evaluate the capacity of 18f-fluorocholine positron emission tomography/computed tomography (FCH PET/CT) to detect biochemical recurrence of prostate cancer and to determine the correlation with PSA kinetics and influence of antiandrogen hormone therapy. PATIENTS AND METHODS: Observational and retrospective study, which included patients with prostate cancer and criteria for biochemical recurrence and/or resistance to castration, according to the European Association of Urology. FCH PET/CT results were classified as positive or negative, using as gold standard the pathology report, findings of other imaging test, and/or clinical follow-up results. The correlation between FCH PET/CT and PSA kinetics (PSA at the time of exploration [PSA-trigger], doubling time [PSAdt] and velocity [PSAva]) was studied and the influence of hormone therapy was analysed. RESULTS: The study included 203 patients. The FCH PET/CT detection rate was 43.3%. The group of patients with FCH PET/CT positive showed more aggressive PSA kinetics (PSAdt: 7.5 months and PSAva 8.37±14.8ng/ml/a) than the FCH PET/CT negative group (PSAdt: 14.5±7.6 months and PSAva: 1.8±3.7ng/ml/a). The detection rate of FCH PET/CT in the subgroup with castration resistance was 89.1%, significantly higher than in the group with radical treatment at 29.9%, p<.001. CONCLUSIONS: FCH PET/CT is useful to detect biochemical recurrence of prostate cancer, especially in patients who receive hormone therapy or more aggressive PSA kinetics.

OBJECTIVES: There is no broad consensus about what diagnostic tests use for CRPC follow up as well as their frequency. Our objective is to review and analyze the most important CRPC follow up patterns described in the literature to date. METHODS: We performed a critical analysis of the recommendations for follow up most universally employed (PCWG3, RADAR, St Gallen consensus, NCCN guidelines, EAU guidelines) RESULTS: CT scan and bone scan are the routine recommended diagnostic tests, in front of other techniques such as PET/CT or MRI, that may improve the diagnostic efficacy but they have the problem of availability and lack of internal validity for follow up. CONCLUSIONS: Follow up is different for non metastatic and metastatic CRPC. For nm CRPC, it is recommended to perform monitoring that includes PSA and imaging tests, without consensus about periodicity. For mCRPC, it is recommendable to do follow up with periodic PSA and imaging tests, since it is possible to have radiological progression without PSA progression.

OBJECTIVES: Androgen deprivation therapy (ADT) in prostate cancer is associated with the appearance of different adverse effects. Among these effects, notable ones that may affect metabolism are osteoporosis and metabolic syndrome. The aim of this study is to analyse lithogenic risk markers three months after initiating treatment with LHRH analogue. METHODS: Pilot study encompassing 15 prostate cancer patients who were candidates for ADT, which they received in the form of quarterly doses of goserelin 10.8 mg. A blood and urine analyses for lithogenic risk, bone and metabolic markers were carried out, as was a study of metabolic syndrome criteria. Statistical analysis was performed with SPSS 17.0, taking P≤.05 to be statistically significant. RESULTS: Patients included in the study had a mean age of 72.46 ± 6.61 years. We observed a significant increase in the percentage of metabolic syndrome (20% versus 46.7%; P<.05) and insulin resistance index (1.87 versus 2.96; P=.01) at 3 months treatment. There was a notable increase in bone remodelling markers and significant increases in 24 h urinary calcium values (9.46 versus 14.57 mg/dl; P=.008), 24 h urinary calcium excretion index (0.10 versus 0.13 mg/dl GF [glomerular filtration]; P=.01) and the fasting calcium/ creatinine ratio (0.107 versus 0.195; P=.007), without any changes to other lithogenous risk markers. CONCLUSIONS: Androgen deprivation therapy can lead to the short-term appearance, primarily when fasting, of hypercalciuria in prostate cancer patients, possibly in association with bone metabolism.

Urology needs models of competencies assessment, although there is a wide range of tools not yet integrated into the official training programs. CONTEXT: At present, there is no universal framework for measuring surgeons' level of competence. Urology training programs should provide and consider knowledge, pyschomotor/cognitive skills, and simulator, cadaver or animal models-based training. Validity is a complex concept that refers to the capacity of the evaluation tool, so it is necessary to demonstrate several types of validation to assure the capacity of a method, reinforced with different reliability tests and calculation of internal consistency between evaluators. OBJECTIVE: Based on a structured dossier of surgical skills, classified by groups, the ESSCOLAP® Basic system was proposed with 5 simulator tasks to evaluate basic laparoscopic skills. Once validated in the JUMISC (Spain), the tool was proposed to extend its scope and implementation in other locations. RESULTS: Our system has not yet demonstrated a full validity in the real clinical setting because a predictive validity needs to be demonstrated on the basis of clinical data. It also suffers from a certain range of subjectivity, thus implying clear and defined criteria for any situation. Factors like the number of evaluators and tasks to assess will influence the reliability tests that measure the degree of agreement between evaluators, so that a higher number of evaluated cases would imply a greater reliability of our system. Finally, we assume that the incorporation of this type of tools implies an added cost, charged to the public and private responsible institutions, which will only be considered cost-effective when it is demonstrated its real and positive traceability in health outcomes. CONCLUSIONS: ESSCOLAP® Basic, of quick and simple implementation capacity, has been validated and calibrated for the evaluation of basic technical skills in laparoscopy.
