PURPOSEA group of international urology and medical oncology experts developed and completed a survey on prostate cancer (PCa) in developing countries. The results are reviewed and summarized, and recommendations on consensus statements for very low-, low-, and intermediate-risk PCa focused on developing countries were developed.METHODSA panel of experts developed more than 300 survey questions of which 66 questions concern the principal areas of interest of this paper: very low, low, and intermediate risk of PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up for very low-, low-, and intermediate-risk PCa in areas of limited resources discussed in this manuscript.RESULTSThe panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion not a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations consider cost-effectiveness and the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time.CONCLUSIONThe voting results and recommendations presented in this document can be used by physicians to support management for very low, low, and intermediate risk of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment for very low, low, and intermediate risk of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

INTRODUCTION: Due to the evolution of extracorporeal lithotripsy equipment (ESWL) and presently, the fact that most part of the equipment does not present ultrasound to localize urinary calculi, a system that allows adapting ultrasound equipment to ESWL equipment was developed, disposing only of fluoroscopy. Thus, this equipment was developed and was tested in urinary stones in canine models, to check its precision in relation to fluoroscopy. METHOD: Seven male dogs were utilized with the introduction, in the bladder through the ureteral route, of chalkstones, with initial localization by fluoroscopy, with a further ultrasound coincidence check localization of the vesical stones, being submitted to ESWL with a 3-hour, 21 days and 60 days follow-up after the procedure. RESULTS: Success of localization in all animals was verified presenting elimination of stones in the first micturitions, after ESWL. No complications were verified in those animals for 60 days. CONCLUSION: We verified that this equipment can lead to an update of the equipment that use only fluoroscopy, increasing in this way, their technical capacity in the treatment of urinary calculi, mainly in cases of non-radiopaque stones.

OBJECTIVE: Surgical correction of the deformity and plaque caused by Peyronie's disease has some important disadvantages and extracorporeal shockwave therapy (ESWT) emerged as a new promising therapy. We evaluated prospectively the efficacy and safety of the association of high dose vitamin E and ESWT as a non-invasive treatment for the disease. MATERIALS AND METHODS: Twenty-five patients 42 to 68 years old (mean = 54) presenting penile deviation and sexual distress caused by Peyronie's disease were treated in a non-invasive manner. The time of penile deviation ranged from 16 to 52 months (mean = 30). All patients had previous unsuccessful treatment for Peyronie's disease. The angulation's deformity of the penis was assessed by photography at home. The patients received vitamin E (l.200 mg daily) during 3 months and underwent 3 to 6 sessions (mean = 3) of ESWT (3,000 to 4,000 shockwaves) at a power level of l to 2 at 1-week intervals. RESULTS: From 25 patients treated, 16 (64%) reported an improvement in penile angulation, with a mean reduction of 21 degrees (10 to 40). Eight patients reported improvement in their spontaneous erections. Overall, the patients presented only minimal bruising at the site of treatment and skin hematoma. Four patients presented urethral bleeding. The mean angulation after treatment in the control group was 48.67 degrees (30 - 70) and in the study group was 24.42 degrees (0 - 70), statistically significant. CONCLUSION: Considering the common complications and the unsatisfactory outcome of the surgical correction for Peyronie's disease, the association of high dose vitamin E and ESWT represents a good option for a non-invasive, effective and safe treatment of the penile deformity.

INTRODUCTION: Sildenafil citrate is a type 5 phosphodiesterase inhibitor, which has demonstrated excellent results in the treatment of erectile dysfunction. The effect of sildenafil citrate in the cavernous arteries of patients with erectile dysfunction has not been established yet. The objective of this study was to assess the effect of sildenafil citrate in the cavernous arteries of patients with erectile dysfunction, following an intracavernous injection of alprostadil. MATERIALS AND METHODS: 29 male patients, with mean age of 53.8 years (32 to 75 years), were prospectively evaluated. The mean time with complaint of erectile dysfunction was 50.5 months (6 to 168 months). Each patient was his own control. Patients underwent a measurement of peak systolic velocity before and after use of sildenafil citrate associated with 5 micrograms of alprostadil, through ultrasonic velocitometry Knoll/MIDUS® system. In the interval between measurements, approximately 15 days, patients used 3 tablets of sildenafil at home with their partners. RESULTS: Using only 5 mcg of alprostadil, average peak systolic velocity was 23.9 cm/s, and when associated to 50 mg of sildenafil it was 24.8 cm/s. Despite the increase in the flow rate caused by sildenafil, the difference was not statistically significant, Zcalculated = - 0.695 NS (Wilcoxon test). Twenty one of the 29 patients (72.4%) showed global improvement in sexual performance with the use of sildenafil citrate at home. There was not a statistically significant correlation between the global response to sildenafil citrate and the increase in the peak systolic velocity. CONCLUSION: We concluded that, even though the use of 50 mg of sildenafil citrate associated with 5 mcg of alprostadil provides an increase in the peak systolic velocity of the cavernous arteries, there was no statistic difference in relation to alprostadil alone. There was no correlation between the global response to sildenafil and the increase in the peak systolic velocity

ABSTRACT Prostate cancer is the second most common cancer and the fifth leading cause of cancer deaths. In Brazil, it is likewise the second most common cancer among men, second only to non-melanoma skin cancers. The aim of this consensus is to align different opinions and interpretations of the medical literature in a practical and patient-oriented approach. The first Brazilian Consensus on the Treatment of Advanced Prostate Cancer was published in 2017, with the goal of reducing the heterogeneity of therapeutic conduct in Brazilian patients with metastatic prostate cancer. We acknowledge that in Brazil the incorporation of different technologies is a big challenge, especially in the Sistema Único de Saúde (SUS), which allows for the disparity in the options available to patients treated in different institutions. In order to update the recommendations and to make them objective and easily accessible, once more a panel of specialists was formed in order to discuss and elaborate a new Brazilian Consensus on Advanced Prostate Cancer. This Consensus was written through a joint initiative of the Brazilian Society of Clinical Oncology (SBOC) and the Brazilian Society of Urology (SBU) to support the clinical decisions of physicians and other health professionals involved in the care of patients with prostate cancer.
