RESUMO

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

RESUMO

Targeted therapy (TT) for prostate cancer (PCa) aims to ablate the malignant lesion with an adequate margin of safety in order to obtain similar oncological outcomes, but with less toxicity than radical treatments. The main aim of this study was to evaluate the recurrence rate (RR) in patients with primary localized PCa undergoing mpMRI/US fusion targeted cryotherapy (FTC). A secondary objective was to evaluate prostate-specific antigen (PSA) as a predictor of recurrences. We designed a prospective single-center single-cohort study. Patients with primary localized PCa, mono or multifocal lesions, PSA ≤ 15 ng/mL, and a Gleason score (GS) ≤ 4 + 3 undergoing FTC were enrolled. RR was chosen as the primary outcome. Recurrence was defined as the presence of clinically significant prostate cancer in the treated areas. PSA values measured at different times were tested as predictors of recurrence. Continuous variables were assessed with the Bayesian t-test and categorical assessments with the chix-squared test. Univariate and logistic regression assessment were used for predictions. A total of 75 cases were included in the study. Ten subjects developed a recurrence (RR: 15.2%), while fifty-six (84.8%) patients showed a recurrence-free status. A %PSA drop of 31.5% during the first 12 months after treatment predicted a recurrence with a sensitivity of 53.8% and a specificity of 79.2%. A PSA drop of 55.3% 12 months after treatment predicted a recurrence with a sensitivity of 91.7% and a specificity of 51.9%. FTC for primary localized PCa seems to be associated with a low but not negligible percentage of recurrences. Serum PSA levels may have a role indicating RR.

RESUMO

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.

RESUMO

BACKGROUND: Some studies showed encouraging results on the efficacy and safety of penile traction therapy after Peyronie's disease (PD) surgery. The early traction therapy (ETT) could be an effective and safe approach to minimize penile shortening in patients undergoing PD surgery. AIM: To evaluate the feasibility, efficacy, and safety of a novel penile splint as ETT in patients with PD undergoing grafting techniques. METHODS: Patients with PD underwent plaque incision and grafting technique; at the end of the procedure, a novel penile splint (ETT) was applied to all patient. The device consisted of 2 10CH intubating stylets, self-adapted to each patient, that kept the penis stretched with the aid of non-absorbable sutures. The total expense for the materials needed to build each penile splint was less than 15 euros. This active traction was maintained for 1-3 weeks; then, we removed the stitches leaving the device on-site for a passive traction. Within 3-4 weeks from surgery, the penile splint was replaced by a standard penile traction device. OUTCOMES: The main outcomes evaluated at 6 months included stretched penile length (SPL), penile curvature, International Index of Erectile Function-erectile function (IIEF-EF) domain, patient satisfaction, and time to first satisfactory sexual intercourse. RESULTS: A total of 46 patients were enrolled. The median preoperative IIEF-EF, penile curvature, and SPL were 27 points, 70°, and 13 cm, respectively. The median follow-up was 15 months. The median postoperative IIEF-EF was 25 points (P < .001). The median residual penile curvature was 10° (P < .001). The median postoperative SPL was 13 cm (P = .269). 8 patients (17.4%) lost 1 cm of SPL; no shortening greater than 1 cm was recorded. The median time to first satisfactory sexual intercourse and patient satisfaction score was 6 weeks and 9 points, respectively. CLINICAL IMPLICATIONS: Our results could pave the way for a new line of research, which in turn could lead to an improvement in the postoperative management of the patient undergoing surgery for PD. STRENGTH & LIMITATIONS: This is the first study evaluating the ETT after PD surgery. The main limitation of this study is the lack of a randomized control group. Other weaknesses are the small sample size and the short follow-up time. CONCLUSION: Our novel penile splint is inexpensive, easy to assemble, and adaptable to the patient. ETT using this novel device, followed by standard traction therapy, seems to be feasible, effective, and safe. Fernández-Pascual E, Manfredi C, Cocci A, et al.

RESUMO

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.

RESUMO

AIM: To evaluate whether positron-emission tomography/computed tomography with 68Ga-PSMA (68Ga-PSMA PET/CT) influences the therapeutic management of patients with primary or recurrent prostate cancer (PCa). BACKGROUND: Although 68Ga-PSMA PET/CT is one of the best options for staging or restaging patients with PCa, its availability is still very limited in Spain. The present study reports the results of the first group of patients in Spain who underwent 68Ga-PSMA PET/CT imaging. MATERIALS AND METHODS: All patients (n = 27) with a histological diagnosis of PCa who underwent 68Ga-PSMA PET/CT prior to the definitive treatment decision at the only centre with this technology in Spain during 2017-2018 were included. Two nuclear medicine physicians and a radiologist reviewed the imaging studies. The clinical impact was assessed from a theoretical perspective, based on the treatment that would have been applied if no data from the 68Ga-PSMA PET/CT were available. RESULTS: Most patients (n = 26; 96%) had persistent disease or biochemical recurrence after radical prostatectomy, radiotherapy, or combined treatment. One patient underwent 68Ga-PSMA PET/CT imaging to stage high-risk PCa. Overall, 68Ga-PSMA PET/CT was positive in 19 patients (70.4%). In 68.75% of these patients, none of the other imaging tests-MRI, CT, or bone scans-performed prior to the 68Ga-PSMA PET/CT were able to detect the presence of cancerous lesions. Overall, the findings of the 68Ga-PSMA PET/CT led to a modification of the therapeutic approach in 62.96% of the patients in the study. CONCLUSIONS: 68Ga-PSMA PET/CT alters the therapeutic approach in a substantial proportion of patients with PCa.

RESUMO

OBJECTIVE: To perform a literature review on the use of cavoscopy during surgery for renal cell carcinoma with vena cava thrombus (RCCVCT), according to the criteria of Evidence-Based Medicine. MATERIAL AND METHODS: We performed a Pubmed search for studies published with the following keywords: "renal tumor thrombus", "renal tumor cavoscopy" and "cystoscopy thrombus", without time limit and in English. With these criteria, 5 articles were identified with a total of 41 patients. All studies found are case series and expert opinions, so the degree of evidence in the use of cavoscopy in RCCVCT is low. RESULTS: RCCVCT surgery is a complex technique, which can reach over 50% 5-year survival, when a complete oncological resection is achieved. One of the keys for surgical success is complete resection of tumor thrombus, having used different techniques for its verification. One of them is cavoscopy, which consists on the introduction of a flexible cystoscope through the cavotomy incision after thrombectomy, checking the lumen of the vena cava with saline serum irrigation. In two series of clinical cases, cavoscopy detected thrombus persistence in 22% and 43% of patients respectively, allowing resection. The entire resected thrombus showed malignancy in several cases. CONCLUSION: Cavoscopy is a technique that improves detection of tumor remnants after thrombectomy in comparison to indirect review methods. Although oncological impact of caval thrombus is controversial, the use of cavoscopy allows a more complete resection of the thrombus, and it may offer a possible increase in the recurrence-free survival of these patients.


OBJETIVO: Realización de una revisión bibliográfica sobre la utilización de la cavoscopia en la cirugía del carcinoma de células renales con trombo en cava (CCRTC), según los criterios de la Medicina Basada en la Evidencia. MATERIAL Y  MÉTODOS: Búsqueda en Pubmed de los estudios publicados con las siguientes palabras clave: "renal tumor thrombus", "renal tumor cavoscopy" y "cystoscopy thrombus", sin límite de tiempo y en inglés. Con estos criterios se identificaron 5 artículos con un total de 41 pacientes. Todos los estudios encontrados son series de casos y opiniones de expertos, por lo que el grado de evidencia en la utilización de la cavoscopia en el CCRTC es baja. RESULTADOS: La cirugía del CCRTC se trata de una técnica compleja, que puede alcanzar una supervivencia a los 5 años de más del 50% cuando se consigue una resección oncológica completa. Una de las claves del éxito de la cirugía es la resección completa del trombo tumoral, habiéndose utilizado diferentes técnicas para su comprobación. Una de ellas es la cavoscopia, que se basa en la introducción de un cistoscopio flexible a través de la cavotomía, revisando la luz de la vena cava con irrigación de suero salino tras la trombectomía. Su realización en dos series de casos clínicos detectó persistencia de trombo en el 22% y 43% de los pacientes respectivamente, permitiendo su resección. La totalidad del trombo resecado demostró malignidad en varios casos.CONCLUSIÓN: La cavoscopia es una técnica que mejora la detección de restos tumorales tras la trombectomía respecto a los métodos indirectos de revisión. Aunque el impacto oncológico del trombo en cava continúa siendo debatido, la utilización de la cavoscopia permite una resección más completa del trombo en cava, pudiendo ofrecer un posible aumento en la supervivencia libre de recurrencia de estos pacientes.

RESUMO

OBJECTIVES: Systematic review of the treatment of small testicular masses (STM) by testicular sparing surgery (TSS), including indications, surgical techniques and complications, as well as the correlation of the analysis of frozen sections (FSE) with the final tumor histology. As a secondary objective we report the initial experience of our center in TSS. MATERIAL AND METHODS: A systematic literature search of the Medline/PubMed database for studies published until June 30, 2019 with the following keywords: "testis sparing surgery", "conservative surgery", "partial orquiectomy" "testicular neoplasms", "testis tumour", "Sex cord tumor", "intraoperative ultrasonography", "enucleation", "excision" or "resection" without time limits, in English and Spanish, identifying 20 articles with a total of 204 TSS, being the series with the largest sample size of 28. In our service, 8 TSS were performed in 6 patients (two bilateral tumor) distributed between 2016-2019. RESULTS: No randomized controlled trials comparing TSS with radical orchiectomy have been reported. The indications for TSS are controversial, especially for patients with normal contralateral testicles. Tumor size has been identified as an important predictor of malignant disease and although there is no approved cut-off point, STM ≤2 cm are the ones that can benefit most from TSS. The use of intraoperative ultrasound (IU) is essential for the location of STM, whether a macroscopic or microsurgical resection is being performed, helping to reduce the rate of complications of the procedure, described in < 6%. The FSE is key at the time of the TSS, discriminating between benign and malignant neoplasms, maintaining a good correlation with the final histology. CONCLUSIONS: TSS for STM allows greater preservation of healthy parenchyma, but should be performed only in selected cases and in experienced centers. The surgical technique is safe and viable, the use of the IU and the FSE of the lesion being essential to facilitate the surgical decision making.


OBJETIVO: Revisión sistemática del tratamiento de pequeñas masas testiculares (PMT) mediante cirugía conservadora testicular (CCT), incluyendo indicaciones, técnicas quirúrgicas y complicaciones, así como la correlación del examen de secciones congeladas (ESC) con la histología final tumoral. Como objetivo secundario reportamos la experiencia inicial de nuestro centro en CCT.MATERIAL Y MÉTODOS: Búsqueda en Pubmed/Medline de estudios publicados hasta el 30 de junio de 2019 con las siguientes palabras clave: "testis sparing surgery", "conservative surgery", "partial orquiectomy" "testicular neoplasms", "testis tumour", "sex cord tumor", "intraoperative ultrasonography", "enucleation", "excision" o" resection" sin límites de tiempo, en inglés y castellano, identificándose 20 artículos con un total de 204 CCT, siendo la serie con mayor tamaño muestral de 28. En nuestro servicio se realizaron 8 CCT en 6 pacientes (dos tumores bilaterales) distribuidos entre 2016-2019. RESULTADOS: No se han informado de ensayos aleatorizados controlados que comparen CCT con orquiectomía radical. Las indicaciones para CCT son controvertidas, especialmente para pacientes con testículos contralaterales normales. Se ha identificado el tamaño tumoral como un predictor importante de enfermedad maligna y aunque no existe un punto de corte aprobado, las PMT ≤2 cm son las que más se pueden beneficiar de CCT. La utilización de ecografía intraoperatoria (EI) es esencial para la localización de PMT, ya se esté realizando una resección macroscópica o con microcirugía, ayudando a disminuir la tasa de complicaciones del procedimiento, descrita en < 6%. El ESC es clave en el momento de la CCT, discriminando entre neoplasias benignas y malignas, manteniendo una buena correlación con la histología final. CONCLUSIONES: La CCT para PMT permite mayor preservación de parénquima sano, pero debe realizarse sólo en casos seleccionados y en centros experimentados. La técnica quirúrgica es segura y viable, siendo claves la utilización de la EI y el ESC de la lesión para facilitar la decisión quirúrgica.

RESUMO

OBJECTIVE: To provide an overview of the meaning and types of virtual reality (VR) system, its current applications in the field of urology and future implications. SYNTHESIS OF THE EVIDENCE: The concept of VR involves the generation of computer environments with which a user can interact directly. Urology technologies and surgical practices are constantly evolving and RV simulation has become an important complement in urologist training curricula, taking into account not only simulations in surgical techniques, but also in non-surgical techniques such as communication and decision making. VR approaches for image-guided surgery have demonstrated potential in the field of urology by supporting guidance for various disorders. An increasing number of pre and intraoperative imaging modalities have been used to create detailed surgical route maps. The tracing of these surgical roadmaps with the surgical vision of real life has been produced in different ways (electromagnetic, acoustic, optical ...), recommending the combination of several approaches to provide a superior result. One of the disadvantages of navigation systems is soft tissue deformations, requiring confirmatory images. Although early studies report that navigation surgeries provide results equal to or greater than conventional approaches, most of the work has been done in relatively small groups of patients, thus requiring studies with larger sample sizes. CONCLUSIONS: The development of VR offers urologists many opportunities, with surgical simulation being one of its most important applications today. Likewise, the first clinical studies have demonstrated the potential of augmented reality (2D and 3D models) to improve surgical accuracy, describing different navigation systems for different urological surgical interventions.


OBJETIVO: Proporcionar una visión general sobre el significado y tipos de sistemas de realidad virtual (RV), sus aplicaciones actuales en el campo de la urología y las implicaciones futuras.SÍNTESIS DE LA EVIDENCIA: El concepto de RV implica la generación de entornos informáticos con los que un usuario puede interactuar directamente. Las tecnologías de urología y las prácticas quirúrgicas están en constante evolución y la simulación de RV se ha convertido en un complemento importante en los planes de estudio de formación de urólogos, teniendo en cuenta no sólo simulaciones en técnicas quirúrgicas, sino también en técnicas no quirúrgicas como comunicación y toma de decisiones.Los enfoques de la RV para la cirugía guiada por imagen han demostrado potencial en el campo de la urología, al apoyar la orientación para diversos trastornos. Se ha utilizado un número cada vez mayor de modalidades de imagen pre e intraoperatorias para crear mapas de ruta quirúrgicos detallados. El rastreo de estas hojas de ruta quirúrgicas, con la visión quirúrgica de la vida real, se ha producido de diferentes formas (electromagnético, acústico, óptico….), recomendándose la combinación de varios enfoques para proporcionar un resultado superior. Uno de los inconvenientes de los sistemas de navegación son las deformaciones de los tejidos blandos, precisando imágenes confirmatorias. Aunque los primeros estudios reportan que las cirugías con navegación proporcionan resultados iguales o superiores a los enfoques convencionales, la mayoría de los trabajos se han realizado en grupos de pacientes relativamente pequeños, precisando por tanto, estudios con mayor tamaño muestral. CONCLUSIONES: El desarrollo de la RV ofrece a los urólogos muchas oportunidades, siendo la simulación quirúrgica una de sus aplicaciones más importantes actualmente. Así mismo, los primeros estudios clínicos han demostrado el potencial de la realidad aumentada (modelos 2D y 3D) para mejorar la precisión quirúrgica, describiéndose diferentes sistemas de navegación para diferentes intervenciones quirúrgicas urológicas.

RESUMO

INTRODUCTION: Radical cystectomy (RC) with pelvic lymphadenectomy is the treatment of choice in patients with muscle invasive bladder cancer (MIBC). OBJECTIVE: To identify clinical and pathological variables that influence global mortality (GM) and cancer specific mortality (CSM) in patients with urothelial bladder tumor (UBT) treated with RC. METHODS: Retrospective analysis of 517 patients diagnosed with UBT and treated with RC between 1986 and 2009. Demographic, clinical, surgical and pathological variables, as well as complications and evolution after RC were collected. A comparative analysis was carried out with Chi square and ANOVA test. Survival analysis was performed with the Kaplan-Meier method and the long-rank test. Univariate and multivariate analysis were performed using Cox regression to identify independent predictors of GM and CSM. RESULTS: 91% of the patients were males with a median age of 66 years. The most frequent local pathological stage was pT3 (32.6%), with lymph node involvement in 23.8% of the patients. After a median follow-up of 34 months, 170 patients were alive and 311 had died from any cause (63.5%), being UBT the cause of death in 225 patients (45%). Rates of global survival and cancer specific survival at 5 and 10 years were 45%/34.3% and 52.5%/46.6% respectively. On the multivariate analysis age ( p = 0.004), ASA ( p = 0.000), the existence of hydronephrosis ( p = 0.01), pT ( p = 0.000) and pN ( p = 0.003) were identified as independent predictors of GM, as well as pT ( p = 0.000) and pN ( p = 0.002) for CSM. CONCLUSIONS: Age, anesthetic risk, presence of hydronephrosis, pT and pN stage were identified as independent predictors of GM, as well as pT and pN stage for CSM.


INTRODUCCIÓN: La cistectomía radical (CR) con linfadenectomía pélvica es el tratamiento de elección en los pacientes con tumor vesical músculoinfiltrante (TVMI). OBJETIVO: Identificar variables clínicas y patológicas que influyen en la mortalidad global (MG) y cáncer-específica (MCE) en pacientes con tumor urotelial vesical (TUV) tratados con CR. MATERIAL Y MÉTODOS: Análisis retrospectivo de 517 pacientes diagnosticados de TUV y tratados con CR entre 1986 y 2009. Se recogieron variables demográficas, clínicas, quirúrgicas y patológicas, así como complicaciones acontecidas y evolución tras CR. Análisis comparativo con test de Chi Cuadrado y ANOVA. Cálculo de supervivencia con el método de Kaplan-Meier y test de long-rank. Análisis univariante y multivariante mediante regresión de Cox para identificar variables predictoras independientes de MG y MCE. RESULTADOS: El 91% de los pacientes fueron varones con mediana de edad de 66 años. El estadio patológico local más frecuente fue el pT3 (32,6%), con afectación ganglionar en el 23,8% de los pacientes. Tras mediana de seguimiento de 34 meses, 170 pacientes estaban vivos y 311 habían fallecido por cualquier causa (63,5%), siendo el TUV la causa de muerte en 225 pacientes (45%). Se objetivaron tasas de supervivencia global y cáncer específica a 5 y 10 años del 45/34,3% y del 52,5/46,6% respectivamente. En el análisis multivariante se identificaron la edad ( p = 0,004), el ASA ( p = 0,000), la existencia de hidronefrosis ( p = 0,01), el pT ( p = 0,000) y el pN ( p = 0,003) como variables predictoras independientes de MG, así como el pT ( p = 0,000) y pN ( p = 0,002) para MCE. CONCLUSIONES: La edad, el riesgo anestésico, la presencia de hidronefrosis, el estadio pT y pN se identificaron como variables predictoras independientes de MG, así como el estadio pT y pN para MCE.

RESUMO

OBJECTIVES: To report our initial experience with laparoscopic Boari flap ureteral reimplantation and to review the main technical elements in ureteral reconstructive surgery. METHODS: In a 10-year period we performed 23 laparoscopic ureteral reimplantations. Three cases required a Boari flap. Two patients presented ureteral stenosis above the iliac vessels and the third one a urothelial tumor of the pelvic ureter. RESULTS: Two cases were completed laparoscopically; the third one was electively converted to open surgery to avoid prolonged OR time. Mean operative time was 276 minutes (270-290 min). There were no intraoperative complications. Mean hospital stay was 6.6 days. One patient presented postoperative UTI (Clavien 2). One patient developed with history of sever arteriopathy and aortorenal by pass developed ureteral stenosis proximal to the ureteral reimplantation eight months after the operation. CONCLUSIONS: Laparoscopic Boari flap ureteral reimplantation is an affective technique for ureteral reconstruction, safe and reproducible, reserved for cases of ureteral pathology in which the distance to bridge between the bladder and the ureteral stump is long.

RESUMO

PURPOSE: To evaluate change in quality of life (QoL) and symptoms in patients with lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH) in conditions of current clinical practice. METHODS: Prospective, longitudinal, multicenter open-label study was carried out in urology outpatient clinics. Patients were ≥40 years of age with an International Prostate Symptom Score (IPSS) score ≥ 8. QoL and symptoms were measured at baseline and 6 months using the Benign Prostatic Hyperplasia Impact Index (BII) and the IPSS. RESULTS: 1713 patients were included for analysis. Mean (SD) IPSS and BII scores at baseline were 16.8 (5.4) and 6.8 (2.6), respectively. 8.9 % (n = 153) of study participants did not receive treatment (watchful waiting, WW), 70.3 % (n = 1204) were prescribed monotherapy (alpha-adrenergic blockers [AB]; phytotherapy [PT, of which 95.2 % was the hexanic extract of Serenoa repens, HESr]; or 5-alpha-reductase inhibitors [5ARI]), and 20.8 % (n = 356) received combined treatment (AB + 5ARI; AB + HESr; others). At 6 months, improvements in QoL were similar across the different medical treatment (MT) groups, both for monotherapy (AB: mean improvement [SD] of 2.4 points [2.4]; PT: 1.9 [2.4]; 5ARI: 2.5 [2.3]) and combined therapy (AB + 5ARI: 3.1 [2.9]; AB + PT: 3.1 [2.5]). There were no clinically significant differences between MT groups and all showed significant improvement over WW (p < 0.05). HESr showed similar efficacy to AB and 5ARI both as monotherapy and in combination with AB. Results on the IPSS were similar. CONCLUSIONS: Improvements in QoL and symptoms were equivalent across the medical treatments most widely used in real-life practice to manage patients with moderate or severe LUTS. HESr showed an equivalent efficacy to AB and 5ARI with fewer side effects.

RESUMO

Prostate cancer (PCa) is a public health problem in western male populations on the basis of it's high incidence and prevalence. Nowadays we come to changes in the diagnostic technologies that deserve special attention and that once applied allow to show the way towards a personalized view of PCa being able to join this modern current trend of the oncologic pathology. In spite of the recognized heterogeneity of the disease; clinical, pathological and genetic variants in genes and the limitations of the PSA as a biomarker to determine the biological aggressiveness of PCa, the certain thing is that the therapeutic final decision is adopted on the basis of a distant information to the wished customization and it moves excessive uncertainty for patients.In this respect the search based on the identification of alterations on the genomic sequence and it's influence in the molecular characterization of the PCa is a constant in the investigation since nowadays. Actually, the progressive adjournment to the clinic of information tumour information that comes from the diagnostic tests related genetic material or their biochemical products, though still in initial phase, already allows to predict relevant changes in molecular characterization of the prostate cancer, in the eventual availability of predictive biomarkers from susceptibility to suffer the disease and of the personalized stratification of risk across the incorporation of newly and interesting molecular and immunohistochemistry biomarkers. Likewise the advances in the perspectives opened with the diagnosis, and the relevance in the decisions of biopsy indications that stem from it are based on the utilization, with the corresponding merger of images, of the multiparametric magnetic resonance (mpMRI) and the new prostate ecographic transrectal images with it's natural evolution towards focal treatments represent, in spite of the recognized complex interpretation of the images, another significant transformation towards the individualization and ideally customization of the clinical decisions opposite to a certain patient with PCa. Events all of them, even more, if they are considered to be combined turn out to be very promising and it's integration brings us over to personalized medicine in PCa since already it happens in others, though still small, neoplastic diseases. All this aspects are summarized and discussed in the present article in the light of the recent communicated information and the reflection and personal experience of the authors. Finally chasing how to improve the clinical managing and the treatment for patients with PCa.

RESUMO

Active surveillance (AS) as a therapeutic option is already integrated as a primary treatment strategy in low risk localized prostate cancer (PCa). There is a recent interest for the search of therapeutic interventions that result in a delay in the progression of such indolent cancers. The evaluation of the possible implication of 5 ARI drugs in the reduction of the risk of progression of PCa was enacted by the results of the clinical trials PCPT (Prostate Cancer Prevention Trial) and REDUCE (Reduction by Dutasteride of Prostate Cancer Events study). The results of the REDEEM clinical trial (Reduction by Dutasteride of clinical progression events in expectant management trial) revealed a delay in PCa progression favoring Dutasteride in comparison with placebo, being advanced age and PSA Density independent predictive factors for pathologic progression. Evidences regarding the influence of 5 ARIs in the evolution of AS patients come from few studies with limited follow up. Thus, the conclusions probably are far from being consiidered as definitive.

RESUMO

INTRODUCTION: The availability of organ donors is a limiting factor for kidney transplants. Donations from non-heart-beating donors (NHBD) can provide as many as one-third of all organs. Controlled patients awaiting cardiac arrest following limitation of life support techniques, or type III Maastricht donors, constitute an alternative that still has yet to be systematically developed. STUDY TYPE: Descriptive series of 10 cases occurring between January and April 2012. METHOD: Over a period of 6 months, we designed a protocol for extracting and managing kidney transplants and providing immunosuppression therapy. Patients are evaluated in accordance with the criteria agreed by a different team responsible for transplant coordination. We established a maximum duration of time between limitation of life-sustaining therapy and death of 120 minutes and 60 minutes warm ischaemia. Two types of graft perfusion were used, one in situ through direct application to the surgical area, and another using ante mortem vascular canalisation. Immunosuppression therapy included induction with thymoglobulin, steroids, and mycophenolate, with introduction of tacrolimus on the seventh day. Data are expressed as median and (range). RESULTS: We included the first 10 cases of kidney transplants with organs from 5 NHBD (type III Maastricht): 4 males, mean age of 57 years (45-66 years), with limitation of life-sustaining therapy due to anoxic encephalopathy (2), intoxication (1), acute stroke (2) and terminal respiratory failure (1). The following mean time intervals were recorded: effective warm ischaemia: 20 minutes (8-23 minutes) and cold ischaemia: 7.5 hours (4-14.1 hours). Recipients had a mean age of 58 years (32-71 years), with various aetiologies (2 cases of glomerulonephritis, 1 polycystic kidney disease, 2 tubulo-interstitial nephropathy, 4 vascular, and 1 unknown), with a mean 31.7 months on haemodialysis (11-84 months); the kidney was a second transplant in two cases. No patients were hyper-immunised. Six patients required a dialysis session at some point, and four had prolonged acute tubular necrosis, over a mean hospitalisation period of 24.5 days (8-44 days). Mean creatinine (Cr) one month after transplantation was 2.1mg/dl (0.7-3.2mg/dl), and mean nadir creatinine was 1.2mg/dl (0.7-3.2mg/dl). One patient did not improve upon Cr values <3.2mg/dl, despite the absence of evidence of toxicity or rejection in a renal biopsy, and the transplant pair reached a Cr of 1.4mg/dl. Throughout the series, similar surgical complications were recorded to those observed in conventional donor situations. CONCLUSIONS: Despite the limitations of this preliminary study, the use of this type of transplant produces favourable short-term evolution. Expanded use of this type of donor could reduce the waiting-list time for a kidney transplant.

RESUMO

Prostate cancer is the sixth most common cancer in the world (in the number of new cases), the third most common cancer in men, and the most common cancer in men in Europe, North America, and some parts of Africa. Different geographical regions have varying incidence and mortality. The risk of prostate cancer is increased by African-American ethnicity, increasing age, positive family history, and other factors such as diet. Nonetheless, the causes of prostate cancer are not well understood compared with other common cancers like lung and breast cancer. The introduction of prostate-specific antigen (PSA) screening made an enormous impact on the incidence of prostate cancer, which increased in the early 1990s and is currently down to pre-PSA screening levels. Screening has caused a change in pattern of disease to an earlier stage but not lower grade. Yet we know little about what causes this disease, in the past 10 years interest in and funding for prostate cancer research have increased and several promising risk modifiers have been identified-eg, genetic predisposition, insulin growth factor (IGF) concentrations, and lycopene consumption.

RESUMO

In this bibliographic review we reexamine the different features in relation to indication, performance and interpretation of prostatic biopsy (PB). The main objective is to place methodological features involving PB in the current scientific scenario, establishing the correlation between the most relevant and analyzing the historic evolution this procedure has followed, particularly over the last two decades. Prostate biopsy has evolved to be a regular element in urologists` daily practice and its learning process has been simplified to the point it can be approached with adequacy during the first years of residency in Urology. This privileged position PB enjoys in daily practice and the performance obtained from it would have not been a reality without optimization of transrectal ultrasound or local anesthesia techniques, yet reviled in some forums, the real responsible of such success. The consensus reached in the various scientific associations, the clinical guidelines of which are widely consulted worldwide, is the best to support the current state of the art, being the starting point for the addition of new improvements to PB.

RESUMO

OBJECTIVE: We report a rare case of advanced testicular cancer that describes the natural progression of testicular cancer without medical treatment. This study also describes the effectiveness of chemotherapy, which was the approach used for treatment. METHODS: 37 year old male with history of mental retardation, presented to the emergency room with an ulcer on his right scrotum that had been present for a few months. He was diagnosed of pT4 embryonal carcinoma by biopsy. CT scan showed multiple lung nodes. He was treated with five cycles of Bleomycin/Etoposide/Cisplatin with complete response after treatment. RESULTS: Testicular tumors are the most frequent solid tumors in males between the ages of 20 and 39 years old. Testicular tumors represent 1% of all neoplasias diagnosed in males and 0.1% of all male deaths due to cancer. Several studies have reported the current real incidence rate of testicular tumors has increased to 3%, which accounts for the diagnosis of 450 new cases of testicular cancer a year in Spain. CONCLUSIONS: The cure rate for patients with intermediate risk non-seminoma is around 70% following a conventional treatment approach of four cycles of BEP. The present case is noteworthy because, in our experience, testicular tumors are diagnosed at an early stage without extensively affecting the skin or simulating another type of epithelial tumor. As a result, the present study describes the natural progression of testicular cancer.
