The association between physical activity and erectile dysfunction: A cross-sectional study in 20,789 Brazilian men.

INTRODUCTION: Erectile dysfunction, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse is associated with impaired quality of life and cardiovascular diseases in men older than 40 years. OBJECTIVE: To evaluate the association between erectile dysfunction and physical activity levels in a large cohort of men. METHODS: Data from 20,789 males aged 40 years and over who participated in the check-up screening between January of 2008 and December of 2018 were included in this study. In this sample, data about erectile dysfunction, physical activity levels, clinical profile and laboratory exams were obtained. Logistic regression models were performed. RESULTS: Individuals with erectile dysfunction were older (49.1 ±6.9 vs. 54.8±8.8 years old, p<0.001), had a higher body mass index (27.6 ±3.9 vs. 28.5 ± 4.3 kg/m2, p<0,001), and presented with a higher prevalence of physical inactivity (25 vs. 19%, p<0.001) than individuals without erectile dysfunction. The multivariate model revealed that age (p<0.001), hypertension (p = 0.001), diabetes mellitus (p<0.001), high body mass index (p<0.001), lower urinary tract symptoms and depressive symptoms (p<0.001) were independent risk factors for erectile dysfunction. Low or high physical activity levels (OR = 0.77; CI95%: 0.68-0.87, p<0.001 and OR = 0.85; CI95%: 0.72-0.99, p = 0.04 respectively) were protective factors against erectile dysfunction. CONCLUSION: Low and high physical activity levels were associated with more than 20% reduction in the risk of erectile dysfunction in men aged 40 years or older.

Current scenario of endourological treatment of kidney stones in brazil: results of a national survey

ABSTRACT Objective: To elucidate the current scenario of endourology in Brazil for the treatment of urinary lithiasis, with an emphasis on regional differences and the reasons why certain techniques are still underutilized. Materials and Methods: An electronic questionnaire was sent by email to the 4,745 members of the Brazilian Urological Society (BSU) in 2016 to collect information on the 3 main endourological procedures used in the treatment of nephrolithiasis: Semi-rigid ureteroscopy (URS), Flexible ureteroscopy (F-URS) and percutaneous nephrolithotripsy (PCNL). Results: A total of 1,267 urologists answered the questionnaire. It was observed that the vast majority perform URS (95.6%), while 80.2% perform F-URS and only 72.1% perform PCNL. Regarding the surgical volume, most perform up to 10 procedures per month (73.4% to 88.2%) and the main impediment was the lack of patients with the pathology (42.1% to 67.7%). The lack of equipment or hospital infrastructure was one of the main limiting factors for rigid (23%) and flexible (38.1%) URS, mainly in the North and Northeast regions of the country. Regarding PCNL, most of them reported lack of practical experience in the method (29.9%). Finally, most urologists expressed interest in taking courses in endourology. Conclusion: Ureteroscopy, rigid or flexible, is already well established in the country, requiring the direction of more resources for its practice, especially in less developed regions. Regarding PCNL a significant part of Brazilian urologists still lack practical experience in this procedure, emphasizing the need for greater investment in teaching this technique.

Práticas integrativas no SUS: Hipnoterapia

Em mais um programa da série especial sobre Práticas Integrativas e Complementares no SUS, as PICS, o programa vai falar sobre a hipnoterapia, um tipo de terapia que usa a hipnose como ferramenta. Vamos desmistificar os mitos e medos a respeito da prática e explicar como a hipnoterapia pode ajudar em processos terapêuticos. Para conhecer melhor o tema, a apresentadora Marcela Morato recebe o psicanalista e hipnólogo Rafael Haddad. Participante: Manoela Uzeda, 41 anos

Ureterocalicostomy with lower pole nephrectomy in a renal transplant: A case report.

As the number of kidney transplants continues to rise, so does the number and complexities of surgical-related complications, which may be associated with increased morbidity and potentially graft loss. Ureteral stenosis, the most prevalent urological complication, may require diverse techniques for surgical correction depending on several recipient and graft abnormalities. Here we report the surgical and clinical outcomes of a 62-year-old man with a posttransplant pyeloureterostomy stricture successfully treated with ureterocalicostomy after a lower pole nephrectomy. Although the resection of renal parenchyma may prevent a stenosis recurrence, surgeons can be reluctant to use this strategy due to the possible negative impact on renal function. We highlight some key steps of the surgical technique to prevent unnecessary allograft lesion and present short-term outcomes, suggesting that this rarely described procedure is a safe and effective alternative treatment for kidney transplant recipients with pyeloureterostomy stenosis.

Flexible ureterorenoscopy in position or fusion anomaly: Is it feasible?

OBJECTIVE: To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). METHOD: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications). RESULTS: The mean stone size was 12.23 +/- 5.43 mm (range 6-22mm), located in the inferior (58.33%) and middle (16.76%) calyceal units, renal pelvis (16.67%) and multiple locations (8.33%). All 13 patients were treated with Ho-Yag laser, using dusting technique (25%), fragmentation and extraction of the calculi (58.33%) and mixed technique (16.67%). We did not have any severe perioperative complication. After 90 days, nine patients (75%) were considered stone free. CONCLUSION: Our data suggest that F-URS is a safe and feasible choice for the treatment of kidney stones in patients with renal ectopic and fusion anomalies.

Resumo Objetivo: Analisar os resultados da ureterorrenolitotripsia flexível (ULT-F) no tratamento de cálculos em rins com anomalia de posição e de fusão (rins em ferradura e rins com vício de rotação). Método: Realizamos a coleta prospectiva dos dados de 13 pacientes com anomalias de fusão e de posição submetidos a ULT-F entre abril de 2011 e abril de 2017. Analisaram-se dados clínicos (idade, gênero, IMC, anormalidades anatômicas, dimensão e localização dos cálculos) e perioperatórios (método de tratamento do cálculo, índice de stone free, tempo de cateter DJ e complicações perioperatórias). Resultados: Nos 13 pacientes, os cálculos mediam em média 12,23 mm +/- 5,43 mm (variando de 6 a 22 mm), em sua maioria distribuídos em apenas um grupo calicinal (58.33% em grupo calicial inferior, 16.67% em grupo calicial médio, 16,67% em pelve e 8,33% em múltiplos cálices). Todos os pacientes foram tratados com utilização de laser Ho-Yag, com fragmentação e retirada de cálculos em sete casos (58,33%), pulverização em três casos (25%) e técnica mista em dois casos (16,67%). Não houve complicações intraoperatórias ou pós-operatórias graves. Após 90 dias, nove pacientes tornaram-se stone free (75%). Conclusão: A ULT-F apresenta-se como método seguro e eficaz no tratamento de litíase em rins com anomalia de posição e de fusão.

Is Gilbert syndrome a new risk factor for breast cancer?

Patients with Gilbert syndrome have an impaired function of the enzyme UGT1A1, responsible for the degradation of 4-OH-estrogens. These elements are produced by the degradation of estrogens and are well-known carcinogens. In theory, patients with Gilbert syndrome accumulate 4-OH-estrogens and, therefore, might have a higher risk for breast cancer, especially when exposed to higher levels of estrogens. If this theory is true, a new risk group for breast cancer would be described, producing new insights in breast carcinogenesis.
