Results: In 20 years, we have treated more than 1,360 patients with this method. We have obtained optimal results mainly in patients with ages between 29 and 45 years old. We have obtained satisfactory results in pa- tients with ages between 45 and 75 years old. Conclusions: This method is used as curative treatment. Improvement of intra and extracellular collagen production has been observed. Rigid and sustained erection produces: vasodilatation, and muscle relaxation Muscle, cellular and cavernous bodies tissue growth.

Lima, Peru Background: The circumcision is the removal of the foreskin from the human penis; nowadays, it has become a routine procedure as a method of hygiene and prevention of sexually transmitted diseases. Objective: To analyze comparatively, the Co2 laser circumcision technique vs. conventional technique in patients of private practice in Lima, Peru, between January 2015 to January 2019. Methods: We report an observational, cross-sectional study of 108 patients who underwent circumcision using the CO2 laser technique (n ¼ 60) vs. the conventional technique (n ¼ 48). Results: We found an average operating time of 51.20 minutes in the conventional technique in comparison to 30.58 minutes for Co2 laser technique, this difference being statistically significant (p <0.0001). The group of patients who underwent laser surgery had less frequency post- surgical complications (21.7%) than patients who underwent conventional technique (81.3%); this difference is statistically significant (p <0.001). Conclusions: There are differences when comparing both surgical tech- niques, especially in terms of surgical time and the presence of complications. Keywords(MESH): Circumcision; Co2 Laser; post-surgical complications.

Sorocaba, Brasil Patient OAF, 66, came to our urology department saying that her penile prosthesis, placed five years ago, was no longer working as before. It was no longer stable and when trying to penetrate the prosthesis "sank" in the perineum. Physical examination revealed penile prosthesis mobility in the region of the penis-scrotal angle, with apparent continuity solution of the stem in the left corpus cavernosum. The computed tomography performed by the usual technique revealed intense artifacts related to attenuation of the x-ray beams resulting from the metallic component of the penile prosthesis, making its evaluation unfeasi- ble. Thereafter, the assisted radiology team of the urology team performed numerous reconstructions, resulting in the least noisy image using a mastoid filter (H 90s very sharp FR). As in the supine position the prosthesis was “bent”, we asked the patient to keep the penis manually pulled through the glans. The report reported a spongy body with morphology, dimensions, texture and appearance within normal standards. Presence of bilateral penile pros- thesis in the corpora cavernosa. The metallic components of the prostheses (malleable section) are intact bilaterally. The prosthesis has normal contours on the right. Apparent disconnection / dislocation between the proximal rigid section and the soft section located in the proximal region of the left prosthesis. Consequently, the proximal end of the malleable section is lat- eralized, and is compatible with palpable nodulation on physical examina- tion. In conclusion, it showed a possible fracture of the penile prosthesis in the silicone region. The patient underwent penile prosthesis replacement surgery. The left prosthesis was actually fractured in the soft silicone region, with continuity solution. To the team’s surprise, the right penile prosthesis also presented the same fracture, although not palpable in the previous physical examination.

São Paulo, Brasil; 2 Psiquiatria, Universidade de São Paulo. São Paulo, Brasil Introduction/objetives: Data from the World Health Organization (WHO) estimate that sexually transmitted infections (STIs) from curable causes - syphilis, chlamydia, gonorrhea and trichomoniasis - affect 376 million people worldwide each year. Since the epidemic began in the 1980s, 35.4 million people have died from causes related to acquired immunodeficiency syndrome (AIDS). The incidence of HIV infections peaked in 1997 and declined until 2005, remaining relatively stable ever since. One of the factors that increase risky sexual behavior is compulsive sexual behavior (CSB), whose study gained emphasis after the 1980s due to its increased prevalence in HIV-positive individuals. The concept of sexual compulsivity has been highly explored in correlation with increased vulnerability to HIV, partic- ularly by the remarkable association with the impulsive personality trait or new sensations seeking. The present study aimed to investigate the preva- lence of STI in sexually compulsive patients. Methods: A literature review of online databases was performed with terms “hypersexuality”, “sexual compulsivity”, “compulsive sexual behavior”, “hy- persexual”, “compulsive sex”, “sexual behavior risk”, “sexually transmitted infection”. Results: Twenty articles were found which reported that compulsive sex is more prone to intentional unsafe sex and HIV contamination, unprotected anal intercourse, sex under the influence of psychoactive substances, multiple partners, higher chance of being diagnosed with an STI and are more likely to identify as barebackers. HIV prevalence ranges from 10.2% to 24.6%; while the prevalence of other STI ranges from 28.4% to 78.6% in these studies. Most studies are conducted in North America and Europe.
