ABSTRACT

ABSTRACT Purpose: To evaluate the erectile function in patients who underwent partial penectomy and identify factors associated with penile functional status. Materials and Methods: We identified patients who underwent partial penectomy due to penile cancer between 2009 and 2014. Clinical and pathological characteristics included patient age at the time of diagnosis, obesity, hypertension, dyslipidemia, diabetes, smoking, metabolic syndrome, Eastern Cooperative Oncology Group (ECOG) status, penile shaft length, tumor size, primary tumor stage (pT), clinical nodal status, and local recurrence. Erectile function was assessed prospectively with the International Index of Erectile Function (IIEF-5) at least 3 months after partial penectomy. Results: A total of 81 patients met analysis criteria. At the diagnosis, the median age was 62 years (range from 30 to 88). Median follow-up was 17 months (IQR 7-36). Of total patients, 37 (45%) had T2 or higher disease. Clinically positive nodes were present in 16 (20%) patients and seven (8.6%) developed local recurrence. Fifty patients (62%) had erectile dysfunction (ED) after partial penectomy, 30% had moderate or severe erectile dysfunction scores. Patients with ED versus without ED were similar in baseline characteristics except for age, penile shaft length, and presence of inguinal adenopathy (p <0.05). Multivariate analysis using logistic regression confirmed that older patients, shorter penile shaft length, and clinically positive lymph node were significantly associated with ED. Conclusion: Partial penectomy due to penile cancer provides adequate local control of the disease, however, proper counselling is important especially in relation to ED consequences. Preservation of penile length yields to more optimal erectile recovery.

ABSTRACT

ABSTRACT Purpose: To describe penile fracture (PF) findings with non-sexual etiology in a referral emergency hospital, with emphasis on demographic data, clinical and intraoperative findings and long-term outcomes. Materials and Methods: Patients with PF of non-sexual cause operated at our institution from January 2014 to January 2019 were submitted to surgical treatment and monitored for at least three months after surgery. Etiology of trauma, epidemiological and clinical presentation data, time to intervention and operative findings were reviewed retrospectively. The evaluation of postoperative erectile function was carried out by filling out the International Index of Erection Function - 5 (IIEF-5). The tool used to assess urinary function was the International Prostate Symptom Score (IPSS) questionnaire. Results: Of a total of 149 patients submitted to surgical treatment for PF, 18 (12%) reported non-sexual etiology. Twelve (66.6%) cases were due to penile manipulation through the act of bending the penis during morning erection, three (16.6%) when rolling over in bed with erect penis, one (5.5%) when embracing the wife during erection, one (5.5%) to laying on the partner with erect penis and the other (5.5%) when sitting on the toilet with an erection. Operative findings were unilateral corpus cavernosum injury in all cases. Only one (5.5%) patient had a partial urethral lesion. Follow-up time varied from 3 to 18 months (mean, 10.1 months). Three (16.6%) patients developed erectile dysfunction six months after surgery. However, all of them responded to treatment with IPDE-5 and reported improvement of erection, with no need for medication, on reevaluation after 18 months. One (5.5%) patient developed penile curvature < 30 degrees. Thirteen (72.2%) patients developed penile nodules. No patient presented voiding complaints during follow-up. Conclusions: PF is a rare urologic emergency, especially with the non-sexual etiology. However, PF should always be considered when the clinical presentation is suggestive, regardless of the etiology. Penile manipulation and roll over in bed were the most common non-sexual causes. These cases are related to low-energy traumas, usually leading to unilateral rupture of corpus cavernosum. Urethral involvement is uncommon but may be present. Early treatment has good long-term clinical outcome, especially when performed in specialized centers with extensive experience in FP.

ABSTRACT

ABSTRACT To evaluate the efficiency of an energy density of 0.05mj/mm2 of low intensity extracorporeal shockwave therapy (Li-ESWT) on erectile dysfunction (ED) patients.A total of 45 ED patients met the inclusion criteria, including 7 PDE5i responders and 38 nonresponders. All the patients have already been delivered 10000 shockwaves of total seven treatment points twice a week for 4 weeks. Simultaneously, questionnaires of International Index of Erectile Function-Erectile Function (IIEF-EF), Erectile Hard Score (EHS) and Minimal Clinical Important Differences (MCID) were evaluated for the efficiency and safety at 8th and 16th weeks.The changes in the IIEF-EF score by MCID suggested that Li-ESWT treatment was effective in 22 PDE5i nonresponders patients (58%) at 8th week. Then at 16th week the number of patients who were effectively treated increased to 27 (71%). Among PDE5i responders, 5 patients (71%) were effective base on MCID at 16th week. Among PDE5i nonresponders 22 patients (58%) achieved erection hard enough for vaginal penetration and increased to 27 (71%) patients at 16th week (EHS ≥3). Moreover, even 3 patients achieved EHS 4 in PDE5i nonresponders at 16th week. Among PDE5i responders, 4 of 7 patients reached EHS of 4 from EHS 3 at 16th week. Apart from this, Li-ESWT treatment was also effective in 9 patients (24%) in PDE5i nonresponders without follow-up PDE5i.Energy flux density (EFD) of 0.05 of Li-ESWT could improve the erectile function of ED patients with PDE5i response. In addition, EFD of 0.05 of Li-ESWT treatment could turn PDE5i nonresponders to responders.

ABSTRACT

SUMMARY INTRODUCTION: The vascular evaluation of the erectile function through Color Duplex-Doppler Ultrasound (CDDU) of the penis can benefit the therapeutic decision-making process. Unfortunately, there is no standard procedure for CDDU conduction, a fact that results in high result-interpretation variability. OBJECTIVE: The aims of this review are to promote greater standardization during CDDU of the penis and discuss the fundamental principles for its accurate conduction. METHODS: CDDU is initially conducted with the penis in the flaccid state; the whole penis must be assessed (images at B mode) with a high-frequency linear transducer (7.5-18 MHz). Intracavernous injection of vasodilating agents (prostaglandin E1, papaverine, phentolamine) is performed to induce a rigid erection. Serial measurements at different times should be taken during the CDDU session and penile rigidity must be assessed in each evaluation. RESULTS: It is important to monitor the erection response after the vasoactive agent (hardness scale), and scanning during the best-quality erection should be contemplated. Manual self-stimulation, audiovisual sexual stimulation (AVSS), and vasoactive agent re-dosing protocols must be taken into account to reduce the influence of psychogenic factors and to help the patient to get the hardest erection possible. Such measurements contribute to the maximal relaxation of the erectile tissue, so the hemodynamic parameters are not underestimated. CONCLUSIONS: CDDU is a relevant specialized tool to assess patients with erectile dysfunction; therefore, this guideline will help to standardize and establish uniformity in its conduction and interpretation, taking into consideration the complexity and heterogeneity of CDDU evaluations of the penis.


RESUMO INTRODUÇÃO: A avaliação vascular da função erétil por meio da ultrassonografia com Doppler colorido do pênis (UDCP) pode trazer benefícios na tomada de decisão. Infelizmente, a falta de padronização na condução de UDCP resulta em alta variabilidade do exame, além de poder comprometer a interpretação dos resultados. OBJETIVO: Os objetivos desta revisão são promover uma maior padronização durante o UDCP e discutir os princípios fundamentais para sua correta condução e interpretação. MÉTODOS: O UDCP é conduzido inicialmente com o pênis no estado flácido; todo o pênis deve ser avaliado (imagens no modo B) com um transdutor linear de alta frequência (7,5-18 MHz). A injeção intracavernosa de agentes vasodilatadores (prostaglandina E1, papaverina, fentolamina) é realizada para induzir uma ereção rígida. Medições seriais em momentos diferentes podem ser realizadas durante a sessão da UDCP e a rigidez peniana deve ser estimada em cada avaliação. RESULTADOS: É importante monitorar a resposta da ereção após o agente vasoativo (escala de rigidez), bem como realizar avaliação hemodinâmica durante a ereção de melhor qualidade. Os protocolos de estimulação sexual manual e audiovisual (AVSS) e redosagem de agente vasoativo devem ser levados em consideração para reduzir a influência de fatores psicogênicos e ajudar o paciente a obter a ereção mais rígida possível. Tais medidas contribuem para o relaxamento máximo do tecido erétil, de modo que os parâmetros hemodinâmicos não são subestimados. CONCLUSÕES: O UDCP é uma ferramenta especializada relevante para avaliar pacientes com disfunção erétil; portanto, esta diretriz ajudará a padronizar e estabelecer uniformidade em sua condução e interpretação, se considerarmos a complexidade e a heterogeneidade das avaliações do pênis por UDCP

ABSTRACT

ABSTRACT Purpose We aimed to evaluate the effects of smoking cessation on the sexual functions in men aged 30 to 60 years. Materials and Methods Male patients aged 30 to 60 years that presented to the smoking cessation polyclinic between July 2017 and December 2018 were prospectively included in the study. The amount of exposure to tobacco was evaluated in pack-year. The patients filled the International Index of Erectile Function (IIEF) form before the cessation and six months after cessation of smoking. Patients were subgrouped according to age, education level and packs/year of smoking and this groups were compared in terms of IIEF total and all of the IIEF domains. Results The evaluations performed by grouping the patients according to age (30-39, 40-49 and 50-60 years) and education level (primary-middle school and high school-university) revealed that the total IIEF scores obtained after smoking cessation were significantly higher compared to the baseline scores in all groups (p=0.007 for the 30-39 years group and p <0.001 for the remaining groups). According to grouping by exposure to smoking (≤25, 26-50, 51-75, 76-100 and 101≥ packs/year), the total IIEF scores significantly increased after smoking cessation in all groups except 101≥ packs/year (p=0.051 for the 101≥ group and p <0.001 for the remaining groups). Conclusions Erectile function is directly proportional to the degree of exposure to smoking, and quitting smoking improves male sexual function in all age groups between 30-60 years of age regardless of pack-year and education level.

ABSTRACT

ABSTRACT Objective To evaluate epidemiological aspects of priapism in patients with sickle cell disease, and these aspects impact on adult sexual function. Methods This was a cross-sectional study including individuals with sickle cell disease who were evaluated at a reference center for sickle cell. Participants completed a structured questionnaire about their sociodemographic characteristics and priapism events. Sexual function was assessed using validated two instruments, the Erection Hardness Score and one about the sex life satisfaction. Results Sixty-four individuals with median aged of 12 (7 to 28) years were interviewed. The prevalence of priapism was 35.9% (23/64). The earliest priapism episode occurred at 2 years of age and the latest at 42 years. The statistical projection was that 71.1% of individuals of the study would have at least one episode of priapism throughout life. Patients with episodes of priapism (10/23) had significantly worse erectile function Erection Hardness Score of 2 [1-3]; p=0.01 and were less satisfied with sexual life 3 [3-5]; p=0.02. Conclusion Priapism is usually present in childhood, and severe episodes are associated with cavernous damage, impairment in the quality of the erection, and lower sexual satisfaction.


RESUMO Objetivo Avaliar aspectos epidemiológicos do priapismo em pacientes com doença falciforme e o impacto desses aspectos na função sexual de adultos. Métodos Trata-se de estudo transversal, que incluiu indivíduos com doença falciforme acompanhados em um centro de referência. Os participantes responderam a um questionário estruturado acerca das características sociodemográficas e eventos de priapismo. A função sexual foi avaliada por meio de dois instrumentos validados, a Escala de Rigidez de Ereção e um sobre satisfação com a vida sexual. Resultados Foram entrevistados 64 indivíduos com média de idade de 12 (7-28) anos. A prevalência de priapismo foi de 35,9% (23/64). O episódio mais precoce ocorreu aos 2 anos de idade e o mais tardio, aos 42 anos. A projeção estatística foi de que 71,1% desses sujeitos teriam pelo menos um episódio de priapismo ao longo da vida. Pacientes adultos com episódios de priapismo (10/23) apresentaram função erétil significativamente pior Escala de Rigidez de Ereção de 2 [1-3]; p=0,01 e estavam menos satisfeitos com a vida sexual 3 [3-5]; p=0,02. Conclusão O priapismo manifesta-se desde a infância, e episódios graves estão associados a dano cavernoso, prejuízo na qualidade da ereção e menor satisfação sexual.

ABSTRACT

RESUMO Objetivo: O objetivo deste estudo foi avaliar o impacto da reabilitação peniana na recuperação da função erétil em pacientes submetidos a ressecção anterior do reto (RAR) ou a prostatectomia radical (PR), comparando os resultados entre esses dois grupos. Materiais e Métodos: Foi realizado estudo de coorte retrospetivo unicêntrico, em pacientes avaliados na nossa consulta multidisciplinar de oncosexologia, entre janeiro de 2015 e janeiro de 2018, submetidos a PR ou RAR (homens) com disfunção sexual. Avaliamos as características oncológicas dos pacientes, idade, estado civil, tipo de disfunção sexual, Índice Internacional de Função Erétil (IIEF-5) na primeira e última consulta e terapêutica utilizada. Foi realizada análise estatística. Resultados: Foram incluídos 55 pacientes, 60% (33) realizaram RAR e 40% (22) PR. Em relação à disfunção sexual após a cirurgia, a disfunção erétil (DE) foi encontrada na maioria dos pacientes (> 95%). Na pontuação inicial do IIEF-5, os pacientes com RAR e PR apresentaram, com maior frequência, DE moderada ou grave (escore 5-11), em 78,8% e 59,1% dos casos, respetivamente. Ao reavaliar a pontuação do IIEF-5 de cada paciente durante o acompanhamento, verificou-se melhoria em 69,7% dos pacientes com RAR e 72,7% dos pacientes com PR (p = 0,81). Quanto à abordagem terapêutica, 84,8% dos pacientes com RAR foram medicados com inibidores da fosfodiesterase-5 (PDE5I) exclusivamente e 3% com injeção de Alprostadil. Os pacientes com PR foram medicados com PDE5I em 63,6% e com injeção de Alprostadil em 31,8% (p <0,05). Conclusões: Apesar das diferenças técnicas destas cirurgias, do ponto de vista sexual, os pacientes se beneficiaram com a reabilitação peniana.


ABSTRACT Purpose: The aim of this study was to evaluate the impact of penile rehabilitation in restoring erectile function in patients submitted to anterior resection of the rectum (ARR) or radical prostatectomy (RP), comparing the results between these two groups. Materials and Methods: We performed a unicenter retrospective cohort study, on patients evaluated in our multidisciplinary oncosexology consultation, between January 2015 and January 2018, submitted to RP or ARR (males) and presenting sexual dysfunction. We evaluate the patient and oncologic characteristics, the type of sexual dysfunction, marital status, assessed the International Index of Erectile Function (IIEF-5) on the first and last consultation and the therapeutic approach. A statistical analysis was performed. Results: A total of 55 patients were included, 60% (33) performed ARR and 40% (22) RP. Regarding the sexual dysfunction after surgery, erectile dysfunction (ED) was found in the majority of patients (>95%). On the initial IIEF-5 scoring, ARR and RP patients had, most frequently, severe or moderate ED (score 5-11), 78.8% and 59.1% respectively. When reassessed the IIEF-5 scoring of each patient during follow-up, there was an improvement in 69.7% of ARR patients and 72.7% of RP patients (p=0.81). Regarding the therapeutic approach, 84.8% of ARR patients used phosphodiesterase-5 inhibitors (PDE5I) exclusively, 3% used Alprostadil injection, while RP patients used 63.6% and 31.8%, respectively (p<0.05). Conclusions: Despite the technical differences of these surgeries, from the sexual point of view these patients benefit with a penile rehabilitation.

ABSTRACT

Abstract Introduction Sexual dysfunction is common in individuals with psychiatric disorders and under psychotropic medication such as antidepressants and antipsychotics. Several scales have been developed to assess sexual function in these patients. The Arizona Sexual Scale (ASEX) is a five-item rating scale that quantifies sex drive, arousal, vaginal lubrication/penile erection, ability to reach orgasm, and satisfaction from orgasm. We describe the translation and cross-cultural adaptation of the ASEX into the Portuguese language, with the goal of contributing to the assessment of sexual function in Portuguese-speaking psychiatric patients under treatment with psychotropic drugs. Methods The translation and cross-cultural adaptation process thoroughly followed the steps recommended by the Task Force of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), namely: preparation, forward translation, reconciliation, back-translation, back-translation review, harmonization, cognitive debriefing, review of cognitive debriefing, finalization, proofreading, and final version. Results The process was successfully completed and no major differences were found between the translation, reconciliation and back-translation phases, with only small adjustments being made. Conclusion The translation of the ASEX was completed successfully, following international reference guidelines. The use of these guidelines is a guarantee of a Portuguese version that is qualitatively and semantically equivalent to the original scale. This availability of this new scale version will enable studies evaluating the sexual function of Portuguese-speaking psychiatric patients. Future studies may assess the validity of the scale for Portuguese-speaking populations.


Resumo Introdução A disfunção sexual é comum em indivíduos com doenças psiquiátricas e sob o uso de medicações como antidepressivos e antipsicóticos. Várias escalas foram desenvolvidas para avaliar a função sexual desses doentes. A Arizona Sexual Scale (ASEX) é uma escala de cinco itens de avaliação que quantifica desejo sexual, excitação, lubrificação vaginal/ereção peniana, capacidade para atingir o orgasmo e satisfação com o orgasmo. Este artigo descreve o processo de tradução e adaptação transcultural da escala ASEX para a língua portuguesa, com o objetivo de contribuir para a avaliação da função sexual dos doentes medicados com fármacos psicotrópicos nos vários países onde se utiliza essa língua. Métodos A tradução e a adaptação transcultural seguiram de forma detalhada os passos recomendados pelo grupo de trabalho da International Society for Pharmacoeconomics and Outcomes Research (ISPOR), nomeadamente: preparação, tradução inicial, reconciliação, retroversão, revisão da retroversão, harmonização, teste cognitivo, revisão do teste cognitivo, finalização, leitura final e versão final. Resultados O processo foi completado com sucesso, e não foram observadas diferenças grandes entre as fases de tradução, reconciliação e retroversão, tendo sido feitos apenas pequenos ajustes. Conclusão A tradução da escala ASEX foi bem-sucedida, seguindo orientações internacionais de referência. A aplicação dessas orientações é a garantia de uma versão em língua portuguesa que é qualitativa e semanticamente equivalente à versão original da escala. A existência desta nova versão da escala permitirá estudos que avaliem a função sexual dos doentes em países nos quais se fale a língua portuguesa. Estudos futuros poderão atestar a validade da escala para essas populações.

ABSTRACT

ABSTRACT Cinnamomum cassia (Cinnamon) is a well-known traditional medicine with therapeutic benefits for centuries. We evaluated the effects of cinnamon essential oil (CEO) and its main component cinnamaldehyde (CA) on human corpus cavernosum (HCC) and rat CC. The essential oil of cinnamon was analyzed for the confirmation of the oil profile. HCC specimens from patients undergoing penile prosthesis surgery (age 48-69 years) were utilized for functional studies. In addition, erectile responses in anesthetized control and diabetic rats were evaluated in vivo after intracavernosal injection of CEO and CA, and rat CC strips were placed in organ baths. After precontraction with phenylephrine (10µM), relaxant responses to CEO and CA were investigated. CA (96.9%) was found as the major component. The maximum relaxation responses to CEO and CA were 96.4±3.5% and 96.0±5.0% in HCC and 97.5±5.5% and 96.8±4.8% in rat CC, respectively. There was no difference between control and diabetic rats in relaxation responses to CEO and CA. The relaxant responses obtained with essential oil and CA were not attenuated in the presence of nitric oxide synthase (NOS) inhibitor, and soluble guanylate cyclase inhibitor (sGS) in CC. In vivo, erectile responses in diabetic rats were lower than in control rats, which was restored after intracavernosal injection of CEO and CA. CEO and CA improved erectile function and relaxation of isolated strips of rat CC and HCC by a NO/cGMP-independent mechanism. Further investigations are warranted to fully elucidate the restorative effects of CEO and CA on diabetic erectile dysfunction.

ABSTRACT

ABSTRACT Introduction Robot-assisted radical prostatectomy (RARP) is the most recent surgical technique for localized prostate cancer. The Da Vinci (Intuitive Surgical, Sunnyvale, CA) system was first introduced in Brazil in 2008, with a fast growing number of surgeries performed each year. Objective Our primary endpoint is to analyze possible predictors of functional outcomes, related to patient and tumor features. As secondary endpoint, describe functional outcomes (urinary continence and sexual potency) from RARP performed in the Sírio-Libanês Hospital (SLH), a private institution, in São Paulo, from April 2008 to December 2015. Materials and Method Data from 104 consecutive patients operated by two surgeons from the SLH (MA and SA) between 2008 and 2015, with a minimum 12 months follow-up, were collected. Patient features (age, body mass index - BMI, PSA, date of surgery and sexual function), tumor features (tumor stage, Gleason and surgical margins) and follow-up data (time to reach urinary continence and sexual potency) were the variables collected at 1, 3, 6 and 12 month and every 6 months thereafter. Continence was defined as the use of no pad on medical interview and sexual potency defined as the capability for vaginal penetration with or without fosphodiesterase type 5 inhibitors. Results Mean age was 60 years old and mean BMI was 28.45 kg/m2. BMI >30kg/m2 (p<0.001) and age (p=0.011) were significant predictors for worse sexual potency after surgery. After 1, 3, 6 and 12 months, 20.7%, 45.7%, 60.9% and 71.8% from patients were potent, respectively. The urinary continence was reached in 36.5%, 80.3%, 88.6% and 92.8% after 1, 3, 6 and 12 months, respectively. Until the end of the study, only one patient was incontinent and 20.7% were impotent. Conclusion Age was a predictor of urinary and erectile function recovery in 12 months. BMI was significant factor for potency recovery. We obtained in a private hospital good functional results after 12 months of follow-up.

ABSTRACT

ABSTRACT Background: Obesity is a worldwide challenging health problem. Weight loss through medical management of obesity has not always been successful, thus, giving rise to the need for surgical intervention. Bariatric surgery has been shown to be helpful for morbidly obese patients. However, studies have also shown the effect of surgery on stone formation, fertility and erectile function. This review summarizes the main findings of several studies that analyze stone formation and fertility in men as well as erectile function post bariatric surgery. The underlying pathophysiologic alterations post bariatric surgery include increased absorption of oxalate leading to hyperoxaluria, hypocitraturia and increased urinary calcium oxalate supersaturation. Contradicting data exist on the effect of bariatric surgery on fertility and erectile function. Further studies are needed to analyze the mechanisms.

ABSTRACT

Introducción: El priapismo se puede describir como una erección peneana prolongada y persistente con duración de más de 4 horas y no asociada con el interés sexual o la estimulación. El priapismo neonatal es una rara entidad con pocos casos reportados hasta la fecha (19 casos hasta el 2017 incluyendo el presente). La experiencia actual en priapismo neonatal se basa prin-cipalmente en informes de casos individuales similares. Por lo tanto, la evaluación, el tratamiento y el seguimiento son desaiantes en la práctica de urología pediátrica. Caso clínico: se presenta paciente masculino, recién nacido de 20 días de vida por cuadro de dermatitis del pañal coinfectada, se ingresa y se brinda manejo, al segundo día de su hospitalización presenta priapismo que resuelve 5 días después. Discusión: El priapismo neonatal de alto lujo es el más común en esta etapa. El conocimiento del cuadro de pria-pismo permite realizar un enfoque adecuado, aplicar de forma sistemática las exploraciones y establecer un diagnóstico y tratamiento para prevenir sus complicaciones. Conclusión: No se conoce una causa exacta de esta patología, por lo que el manejo será en la mayoría de los casos conservador...(AU)

ABSTRACT

ABSTRACT Objectives: Evaluate the demographic data, etiology, operative findings and results of surgical treatment of penile fracture (PF) in men who have sex with men(MSM) with emphasis on sexual complications. Materials and Methods: We studied 216 patients underwent surgical correction of PF at our hospital. Patients self-identified as MSM were followed for at least 6 months. Demographic data, presentation, operative findings, International Index of Erection Function - 5 (IIEF-5) and the Premature Ejaculation Diagnostic Tool. Results: Of 216 PF cases, 4 (1.8%) were MSM. All cases resulted from sexual activity and all patients reported using the "doggy style" position during anal intercourse. Unilateral or bilateral injury of corpus cavernosum was found in 2 patients each. One (25%) patient had complete urethral injury associated with bilateral corpus cavernosum lesion. During the follow-up period, all patients developed some type of sexual complication. One patient reported penile pain during intercourse. Another patient experienced low sexual desire and premature ejaculation. This patient was also dissatisfied with the aesthetic result of the surgical scar and complained about decreased penis size after surgery. The third case developed delayed ejaculation. The fourth patient experienced mild to moderate erectile dysfunction. This same patient presented with penile curvature. Finally, palpable fibrotic nodules in the operative area were observed in all cases. Conclusions: Sexual activity in the "doggy style" position was the commonest cause of PF in MSM. Sexual dysfunction is always present in gay man after surgery for PF. However, additional studies with larger samples should be coinducted.

ABSTRACT

ABSTRACT Introduction: The study was aimed to assess the presence of actual differences between the objective and the perceived magnitude of a curvature between patients affected by Peyronie's disease (PD) and congenital penile curvature (CPC). Materials and Methods: Wee analysed a cohort of 88 consecutive patients seeking medi- cal help for either CPC or PD. All patients were invited to provide a self-made drawing of their penis in erection in order to obtain self-provided description of the deformity. An objective measurement of the deformity was also performed drawing two intersecting lines through the center of the distal and proximal straight section of the penile shaft. Results: Our findings showed significant differences between patient self-estimation and the objective measurements of the penile angulation performed by trained experts, with only 32% of patients correctly assessing their own curvature. Overall, patients tended to overestimate (56%) their degree of curvature, but the results are different in patients with PD than those with CPC. In the 60 men (68%) who did not accurately assess their curvature, PD patients generally overestimated their curvature versus CPC patients (67% vs 16%). On the contrary CPC patients underestimated their curvature compared to PD (42% vs. 4%). Conclusion: In order to improve patients' satisfaction rates, the surgeon needs to take into consideration the patient's perception of the deformity when planning the type of surgical correction.
