Introduction: Renal cell carcinoma (RCC) is the ninth most common cancer in men, and the 14th most common cancer in women. It has been reported that the incidence of RCC is rising. These changes are more common in developed countries because of better screening programs and disease registry. The aim of this article is to review the epidemiology of RCC around the world. Methods: A literature review on four databases was performed: PubMed, Embase, Lilacs, and Scielo. Studies of incidence, prevalence, mortality, and survival of RCC were taken from different countries. Studies included were published in the last 10 years. Two reviewers independently selected the studies. Results: A total of 5275 references were reviewed by title and abstract. In the end, 42 references were selected for full-text review. The global incidence and prevalence of cancer vary. The highest incidence was described in North America and Northern Europe. In Canada, by 2007 the incidence was 17.9/100 000 and 10.3/100 000 in males and females, respectively. Developing countries like Colombia have fewer incidence rates, finding less information in poor-income areas. Conclusions:We have seen a rise in the incidence and mortality of RCC globally. There is an association between RCC and smoking, obesity, hypertension, and socioeconomic status. Seeing the epidemiological data from some regions in developing countries and the lack of specialists in those places, it can be deduced the existence of an underreporting of

A case of giant condyloma acuminatum of the scrotum is reported. It was initially diagnosed as a low grade squamous carcinoma. This neoplasm is closely related to Human Papillomavirus, mainly HPV 6 and HPV 11, and may be clinically indistinguishable from squamous carcinoma. The histological appearance is benign, however, its clinical behaviour is similar to verrucous carcinoma. A review of previously reported cases has been undertaken. The true significance of this lesion and management are discussed. Early aggressive therapy is recommended.

Introduction Ureteral stents are widely used tools in the daily practice of the urologist due to the fact that they solve the endo-and extraluminal ureteral obstructions, enabling an adequate urine flow. They are the preferred tool because they are easy to insert and versatile, and are used to treat various urologic pathologies; nonetheless, they are not exempt from complications. Objectives To present an update in the use of JJ stents, describing their main associated symptoms and complications, indications and newest developments. Materials and MethodsWe performed a literature review in the Embase, Pubmed and Google Scholar databases, with the following terms and cross-references: ureteral stent; diagnosis; treatment; and urology, restricting the search to the past 7 years. A total of 428 articles were found, and 49 were used in the revision. Results We described the symptoms and complications associated with the use of JJ stents and their prevention, their use in the treatment of lithiasis and oncologic diseases, the utility of metallic stents, and new designs and improvements in their development.Conclusions JJ stents remain a very useful tool in the daily practice of the urologist, but are not exempt from having adverse effects and complications. There have been advances that decrease the adverse effects associated with their use, mainly infection, symptoms associated to the insertion, and risk of incrustation. ResumenIntroducción Los catéteres ureterales son una herramienta ampliamente usada en la práctica diaria del urólogo, dado a que alivian la obstrucción endo y extraluminal ureteral, permitiendo así el adecuado flujo de orina. Se prefieren por encima de otros métodos por su facilidad de inserción y su versatilidad de uso dentro de las distintas patologías urológicas; sin embargo, no están exentos de complicaciones. Objetivos Presentar una actualización en el uso de catéteres JJ que incluya información acerca de los síntomas y complicaciones, sus indicaciones de uso y novedades.
