[Knowledge and HIV/AIDS risk behaviors of Chilean adolescents attending urban and rural schools. Is it necessary to focus the prevention strategies according to territorial relevance?].

Background: HIV infection has sustained increased in the Chilean young population. In order to focus on sexual education in adolescents, it is first necessary to establish the degree of knowledge and risk behaviors in this group. Therefore, this study aimed to compare the degree of knowledge and HIV/AIDS risk behaviors in adolescents from rural and urban schools.

ANalogical UroFlowmetry (ANUF): Correspondence Between This New Visual Pictogram and Uroflowmetry in Men With Lower Urinary Tract Symptoms: A new approach for the study of male micturition dynamics.

Objective: To study the correlation between a new visual tool (ANalogical UroFlowmetry (ANUF)) and uroflowmetry (UF) parameters when performed to assess male lower urinary tract symptoms (MLUTS).

Methods: We configured an original pictogram composed of 4 different urine streams. In the setting of a University Hospital based prospective study where 545 men were enrolled between September 2018 and January 2019.

Do candidates for penile implant prefer their doctors or another implanted patient as their information source? Results of a pilot study.

Introduction: Erectile dysfunction incidence is about 19-26 cases for every 1000 men/year, requiring about 20,000 penile implants/year. There is high demand for information on the part of patients, however, there is a lack of evidence about the sources of information prior to penile implant and the figure of the Expert Patient (EP) has never been described in this area.

Aims: To evaluate the sources of information used by candidates for penile implant as well as to describe the role of the EP as an information source.

Congenital bilateral absence of the vas deferens (CBAVD): do genetic disorders modify assisted reproductive technologies outcomes?

Objectives: To evaluate the impact of common Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene mutations, 5T polymorphism and presence of severe Cystic Fibrosis (CF) on fertility outcomes with Assisted Reproductive Techniques (ART) in patients presenting Congenital Bilateral Absence of Vas Deferens (CBAVD).

Methods: A comparative observational cohort study was performed from 2002 to 2018 with 51 patients with diagnosis of CBAVD. Presence of CFTR mutations and 5T, CF, pregnancy and newborn rates were analyzed.

Local Treatment of Penile Prosthesis Infection as Alternative to Immediate Salvage Surgery.

Introduction: Penile prosthesis (PP) is the established treatment for patients with erectile dysfunction (ED) who do not respond to phosphodiesterase inhibitors and intracavernosal injections. In general, these devices have been largely successful but there are not free of serious complication such as PP infection (PPI). PPI requires immediate surgical removal or salvage rescue of the PP.
