- Risk Factors for Male Lower Urinary Tract Symptoms: The Role of Metabolic Syndrome and Androgenetic Alopecia in a Latin American Population(2013) BARBOSA, Joao Arthur B. A.; MURACCA, Eduardo; NAKANO, Elcio; PARANHOS, Mario; NATALINO, Renato; CORDEIRO, Paulo; SROUGI, Miguel; ANTUNES, Alberto AzoubelOBJECTIVE To evaluate the association of male lower urinary tract symptoms (LUTS) with metabolic syndrome (MetS) and androgenetic alopecia in a Latin American population. METHODS We enrolled 907 patients for prospective evaluation at a single institution. LUTS were evaluated with the International Prostate Symptom Score (IPSS). Subjects were evaluated with respect to hypertension, diabetes, dyslipidemia, previous cardiovascular events, body mass index (BMI), waist and hip circumference, and a laboratorial investigation including prostate-specific antigen (PSA), C-reactive protein (CRP), and gonadal steroids. Alopecia was classified according to the Norwood-Hamilton scale. RESULTS Mean patient age was 61.0 years; 57.5% of subjects had moderate/severe LUTS; MetS was present in 17.2% of subjects and 53.9% were classified as bald. Age, hypertension, diabetes, dyslipidemia, alopecia, previous cardiovascular event, and elevated waist-to-hip ratio (WHR) were associated with moderate/severe LUTS and with storage symptoms (P < .05). On multivariable analysis, age (odds ratio [OR] 2.30, 95% confidence interval [CI] 1.63-3.25), cardiovascular events (OR 1.73, 95% CI 1.07-2.78), and WHR (OR 1.65, 95% CI 1.13-2.40) were independent predictors for LUTS. For storage symptoms, age (OR 1.80, 95% CI 1.28-2.54), cardiovascular event (OR 2.07, 95% CI 1.27-3.39), WHR (OR 1.54, 95% CI 1.06-2.25), and MetS (OR 1.70, 95% CI 1.01-2.86) were independent risk factors. Age and cardiovascular event were the only independent predictors for voiding symptoms. CONCLUSION Components of the MetS were strongly associated with moderate and severe LUTS. WHR and cardiovascular events were independent predictors of voiding and storage symptoms, and MetS was an independent predictor of storage symptoms. Alopecia was not an independent predictor of LUTS. UROLOGY 82: 182-188, 2013. (C) 2013 Elsevier Inc.
conferenceObject LONG-TERM EVALUATION OF TRANSURETHRAL INCISION OF THE PROSTATE FOR TREATMENT OF BENIGN PROSTATE HYPERPLASIA: ANALYSIS OF 75 CASES WITH A MEAN 8-YEAR FOLLOW-UP PERIOD(2015) CORDEIRO, Paulo; BARONE, Hugo; YOSHINAGA, Eduardo Muracca; NAKANO, Elcio; NAHAS, William C.; SROUGI, Miguel; ANTUNES, Alberto A.- Interactions between Lower Urinary Tract Symptoms and Cardiovascular Risk Factors Determine Distinct Patterns of Erectile Dysfunction: A Latent Class Analysis(2013) BARBOSA, Joao A. B. A.; MURACCA, Eduardo; NAKANO, Elcio; ASSALIN, Adriana R.; CORDEIRO, Paulo; PARANHOS, Mario; CURY, Jose E.; SROUGI, Miguel; ANTUNES, Alberto A.Purpose: An epidemiological association between lower urinary tract symptoms and erectile dysfunction is well established. However, interactions among multiple risk factors and the role of each in pathological mechanisms are not fully elucidated Materials and Methods: We enrolled 898 men undergoing prostate cancer screening for evaluation with the International Prostate Symptom Score (I-PSS) and simplified International Index of Erectile Function-5 (IIEF-5) questionnaires. Age, race, hypertension, diabetes, dyslipidemia, metabolic syndrome, cardiovascular disease, serum hormones and anthropometric parameters were also evaluated. Risk factors for erectile dysfunction were identified by logistic regression. The 333 men with at least mild to moderate erectile dysfunction (IIEF 16 or less) were included in a latent class model to identify relationships across erectile dysfunction risk factors. Results: Age, hypertension, diabetes, lower urinary tract symptoms and cardiovascular event were independent predictors of erectile dysfunction (p < 0.05). We identified 3 latent classes of patients with erectile dysfunction (R-2 entropy = 0.82). Latent class 1 had younger men at low cardiovascular risk and a moderate/high prevalence of lower urinary tract symptoms. Latent class 2 had the oldest patients at moderate cardiovascular risk with an increased prevalence of lower urinary tract symptoms. Latent class 3 had men of intermediate age with the highest prevalence of cardiovascular risk factors and lower urinary tract symptoms. Erectile dysfunction severity and lower urinary tract symptoms increased from latent class 1 to 3. Conclusions: Risk factor interactions determined different severities of lower urinary tract symptoms and erectile dysfunction. The effect of lower urinary tract symptoms and cardiovascular risk outweighed that of age. While in the youngest patients lower urinary tract symptoms acted as a single risk factor for erectile dysfunction, the contribution of vascular disease resulted in significantly more severe dysfunction. Applying a risk factor interaction model to prospective trials could reveal distinct classes of drug responses and help define optimal treatment strategies for specific groups.

Is there any influence of musical instrument and video game skills on surgical performance?(2015) YAMACAKE, Kleiton Gabriel Ribeiro; NAKANO, Elcio Tadashi; SOARES, Iva Barbosa; CORDEIRO, Paulo; SROUGI, Miguel; ANTUNES, Alberto AzoubelObjective: To evaluate the learning curve for transurethral resection of the prostate (TURP) among urology residents and study the impact of video game and musical instrument playing abilities on its performance. Material and methods: A prospective study was performed from July 2009 to January 2013 with patients submitted to TURP for benign prostatic hyperplasia. Fourteen residents operated on 324 patients. The following parameters were analyzed: age, prostate-specific antigen levels, prostate weight on ultrasound, pre- and postoperative serum sodium and hemoglobin levels, weight of resected tissue, operation time, speed of resection, and incidence of capsular lesions. Gender, handedness, and prior musical instrument and video game playing experience were recorded using survey responses. Results: The mean resection speed in the first 10 procedures was 0.36 g/min and reached a mean of 0.51 g/min after the 20th procedure. The incidence of capsular lesions decreased progressively. The operation time decreased progressively for each subgroup regardless of the difference in the weight of tissue resected. Those experienced in playing video games presented superior resection speed (0.45 g/min) when compared with the novice (0.35 g/min) and intermediate (0.38 g/min) groups (p=0.112). Musical instrument playing abilities did not affect the surgical performance. Conclusion: Speed of resection, weight of resected tissue, and percentage of resected tissue improve significantly and the incidence of capsular lesions reduces after the performance of 10 TURP procedures. Experience in playing video games or musical instruments does not have a significant effect on outcomes.
