- Quality of Life and Clinical Symptom Improvement Support Prostatic Artery Embolization for Patients with Acute Urinary Retention Caused by Benign Prostatic Hyperplasia(2013) CARNEVALE, Francisco C.; MOTTA-LEAL-FILHO, Joaquim M. da; ANTUNES, Alberto A.; BARONI, Ronaldo H.; MARCELINO, Antonio S. Z.; CERRI, Luciana M. O.; YOSHINAGA, Eduardo M.; CERRI, Giovanni G.; SROUGI, MiguelPurpose: To show that prostatic artery embolization (PAE) improves quality of life (QoL) and lower urinary tract symptoms in patients with acute urinary retention caused by benign prostatic hyperplasia (BPH). Materials and Methods: This was a single-center prospective study of PAE in 11 patients with BPH managed With indwelling. urinary catheters. International Prostate Symptom Score (IPSS), ultrasound, magnetic resonance (MR) imaging, QoL, and urodynamic tests were used. to assess outcomes. Prostate size ranged from 30 to 90 g, and embolizations were performed with 300-500-mu m Embosphere microspheres. Results: The rate of technical success (ie, bilateral PAE) was 75%, and the rate of clinical success (ie, catheter removal and symptom improvement) was 91% (10 of 11 patients). Postembolization syndrome manifested as mild pain in the perineum, retropubic area, and/or urethra. Ten of 11 patients urinated spontaneously after Foley catheter removal 4-25 days after PAE (mean, 12.1 d). No major complications Were observed. Follow-up ranged from 19 to 48 months. than asymptomatic patient, a discrete area of hypoperfusion: suggesting small ischemia of the bladder was observed on 30-day MR imaging follow-up, but the bladder was normal on 90-day MR imaging. After 1 year, mean prostate volume reduction was greater than 30%, symptoms were mild (mean IPSS, 2.8 +/- 2.1; P = .04),. no erectile dysfunction was observed, and QoL,improved significantly (mean , 0.4 +/- 0.5; P = .001) using the paired t test. Conclusions: Patients with severe symptoms and acute urinary retention caused by BPH can be treated Safely by PAE, which improves clinical symptoms and QoL.
- Evaluation of hemodynamic effects of xenon in dogs undergoing hemorrhagic shock(2013) FRANCESCHI, Ruben C.; MALBOUISSON, Luiz; YOSHINAGA, Eduardo; AULER JR., Jose Otavio Costa; FIGUEIREDO, Luiz Francisco Poli de; CARMONA, Maria Jose C.OBJECTIVES: The anesthetic gas xenon is reported to preserve hemodynamic stability during general anesthesia. However, the effects of the gas during shock are unclear. The objective of this study was to evaluate the effect of Xe on hemodynamic stability and tissue perfusion in a canine model of hemorrhagic shock. METHOD: Twenty-six dogs, mechanically ventilated with a fraction of inspired oxygen of 21% and anesthetized with etomidate and vecuronium, were randomized into Xenon (Xe; n = 13) or Control (C; n = 13) groups. Following hemodynamic monitoring, a pressure-driven shock was induced to reach an arterial pressure of 40 mmHg. Hemodynamic data and blood samples were collected prior to bleeding, immediately after bleeding and 5, 20 and 40 minutes following shock. The Xe group was treated with 79% Xe diluted in ambient air, inhaled for 20 minutes after shock. RESULT: The mean bleeding volume was 44 mL.kg(-1) in the C group and 40 mL.kg(-1) in the Xe group. Hemorrhage promoted a decrease in both the cardiac index (p<0.001) and mean arterial pressure (p<0.001). These changes were associated with an increase in lactate levels and worsening of oxygen transport variables in both groups (p<0.05). Inhalation of xenon did not cause further worsening of hemodynamics or tissue perfusion markers. CONCLUSIONS: Xenon did not alter hemodynamic stability or tissue perfusion in an experimentally controlled hemorrhagic shock model. However, further studies are necessary to validate this drug in other contexts.
- Clinical, Laboratorial, and Urodynamic Findings of Prostatic Artery Embolization for the Treatment of Urinary Retention Related to Benign Prostatic Hyperplasia. A Prospective Single-Center Pilot Study(2013) ANTUNES, Alberto A.; CARNEVALE, Francisco C.; LEAL FILHO, Joaquim M. da Motta; YOSHINAGA, Eduardo M.; CERRI, Luciana M. O.; BARONI, Ronaldo H.; MARCELINO, Antonio S. Z.; CERRI, Giovanni G.; SROUGI, MiguelThis study was designed to describe the clinical, laboratorial, and urodynamic findings of prostatic artery embolization (PAE) in patients with urinary retention due to benign prostatic hyperplasia (BPH). A prospective study of 11 patients with urinary retention due to BPH was conducted. Patients underwent physical examination, prostate specific antigen (PSA) measurement, transrectal ultrasound, and magnetic resonance imaging. International prostate symptom score (IPSS), quality of life (QoL), and urodynamic testing were used to assess the outcome before and after 1 year. Clinical success was 91 % (10/11 patients) with a mean follow-up of 22.3 months (range, 12-41 months). At the first year follow-up, the mean IPSS score was 2.8 points (p = 0.04), mean QoL was 0.4 points (p = 0.001), mean PSA decreased from 10.1 to 4.3 ng/mL (p = 0.003), maximum urinary flow (Qmax) improved from 4.2 to 10.8 mL/sec (p = 0.009), and detrusor pressure (Pdet) decreased from 85.7 to 51.5 cm H2O (p = 0.007). Before PAE, Bladder Outlet Obstruction Index (BOOI) showed values > 40 in 100 % of patients. After PAE, 30 % of patients were > 40 (obstructed), 40 % were between 20 and 40 (undetermined), and 30 % were < 20 (unobstructed). Patients with a BOOI < 20 had higher PSA values at 1-day after PAE. Clinical and urodynamic parameters improved significantly after PAE in patients with acute urinary retention due to BPH. Total PSA at day 1 after PAE was higher in patients with unobstructed values in pressure flow studies.
- 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.
conferenceObject LOW-VOLUME PROSTATE IN BENIGN PROSTATIC HYPERPLASIA (BPH): A RISK FACTOR FOR SYMPTOMATIC BLADDER DIVERTICULA REQUIRING SURGICAL TREATMENT(2015) YOSHINAGA, Eduardo Muracca; NAKANO, Elcio; MARCHINI, Giovanni S.; OYAMA, Renato Hajime; CORDEIRO, Paulo; NAHAS, William C.; SROUGI, Miguel; ANTUNES, Alberto A.conferenceObject THE PAINFUL PELVIC SYMPTOMS IN AGING MEN. THE RESULTS OF POPULATION-BASED SAMPLE OF MEN(2016) NAKANO, Elcio; CONTI, Paulo Sajovic de; YOSHINAGA, Eduardo Muracca; NAHAS, William C.; SROUGI, Miguel; ANTUNES, Alberto- Transurethral Resection of the Prostate (TURP) Versus Original and PErFecTED Prostate Artery Embolization (PAE) Due to Benign Prostatic Hyperplasia (BPH): Preliminary Results of a Single Center, Prospective, Urodynamic-Controlled Analysis(2016) CARNEVALE, Francisco C.; ISCAIFE, Alexandre; YOSHINAGA, Eduardo M.; MOREIRA, Airton Mota; ANTUNES, Alberto A.; SROUGI, MiguelTo compare clinical and urodynamic results of transurethral resection of the prostate (TURP) to original and PErFecTED prostate artery embolization (PAE) methods for benign prostatic hyperplasia. We prospectively randomized 30 patients to receive TURP or original PAE (oPAE) and compared them to a cohort of patients treated by PErFecTED PAE, with a minimum of 1-year follow-up. Patients were assessed for urodynamic parameters, prostate volume, international prostate symptom score (IPSS), and quality of life (QoL). All groups were comparable for all pre-treatment parameters except bladder contractility and peak urine flow rate (Q (max)), both of which were significantly better in the TURP group, and IIEF score, which was significantly higher among PErFecTED PAE patients than TURP patients. All groups experienced significant improvement in IPSS, QoL, prostate volume, and Q (max). TURP and PErFecTED PAE both resulted in significantly lower IPSS than oPAE but were not significantly different from one another. TURP resulted in significantly higher Q (max) and significantly smaller prostate volume than either original or PErFecTED PAE but required spinal anesthesia and hospitalization. Two patients in the oPAE group with hypocontractile bladders experienced recurrence of symptoms and were treated with TURP. In the TURP group, urinary incontinence occurred in 4/15 patients (26.7 %), rupture of the prostatic capsule in 1/15 (6.7 %), retrograde ejaculation in all patients (100 %), and one patient was readmitted for temporary bladder irrigation due to hematuria. TURP and PAE are both safe and effective treatments. TURP and PErFecTED PAE yield similar symptom improvement, but TURP is associated with both better urodynamic results and more adverse events.
- Prostatic Artery Embolization for Treatment of Benign Prostatic Hyperplasia in Patients with Prostates > 90 g: A Prospective Single-Center Study(2015) ASSIS, Andre Moreira de; MOREIRA, Airton Mota; RODRIGUES, Vanessa Cristina de Paula; YOSHINAGA, Eduardo Muracca; ANTUNES, Alberto Azoubel; HARWARD, Sardis Honoria; SROUGI, Miguel; CARNEVALE, Francisco CesarPurpose: To describe the safety and efficacy of prostatic artery embolization (PAE) with spherical microparticles to treat lower urinary tract symptoms associated with benign prostatic hyperplasia in patients with prostate volume > 90 g. Materials and Methods: This prospective, single-center, single-arm study was conducted in 35 patients with prostate volumes ranging from 90-252 g. Mean patient age was 64.8 years (range, 53-77 y). Magnetic resonance imaging, uroflowmetry, and the International Prostate Symptom Score (IPSS) were used to assess clinical and functional outcomes. Results: Mean prostate size decreased significantly from 135.1 g before PAE to 91.9 g at 3 months of follow-up (P < .0001). Mean IPSS and quality-of-life index improved from 18.3 to 2.7 and 4.8 to 0.9 (P < .0001 for both), respectively. A significant negative conelation was observed between prostate-specific antigen at 24 hours after PAE and IPSS 3 months after PAE (P = .0057). Conclusions: PAE is a safe and effective treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia in patients with prostate volume > 90 g. Excessively elevated prostate-specific antigen within 24 hours of PAE is associated with; lower symptom burden in short-term follow-up.
