Objective: To gather information on penile cancer epidemiologic trends and its economic impact on the Brazilian Public Health System across the last 25 years. Methods: The Brazilian Public Health System database was used as the primary source of data from January 1992 to December 2017. Mortality and incidence data from the Instituto Nacional de Câncer José Alencar Gomes da Silva was collected using the International Classification of Diseases ICD10 C60. Demographic data from the Brazilian population was obtained from the last census by the Brazilian Institute of Geography and Statistics, performed in 2010 and its 2017 review. Results: There were 9,743 hospital admissions related to penile cancer from 1992 to 2017. There was a reduction (36%) in the absolute number of admissions per year related to penile cancer in 2017, as compared to 1992 (2.7 versus 1.7 per 100,000; p<0.001). The expenses with admissions related to this condition in this period were US$ 3,002,705.73 (US$ 115,488.68/year). Approximately 38% of the total amount was spent in Northeast Region. In 1992, penile cancer costed US$ 193,502.05 to the public health system, while in 2017, it reduced to US$ 47,078.66 (p<0.02). Penile cancer incidence in 2017 was 0.43/100,000 male Brazilian, with the highest incidence rate found in the Northeast Region. From 1992 to 2017, the mortality rates of penile cancer in Brazil were 0.38/100,000 man, and 0.50/100,000 man in the North Region. Conclusion: Despite the decrease in admissions, penile cancer still imposes a significant economic and social burden to the Brazilian population and the Public Health System.
Objective: To analyze mortality rates and hospitalization data after radical cystectomy in each public healthcare center in São Paulo in the last decade, considering the number of surgeries performed at each center. Methods: This study included patients from the Departamento de Informática do Sistema Único de Saúde from the state of São Paulo, who underwent radical cystectomy between 2008 and 2018. Data analyzed included organization name, number of procedures/year, in-hospital death rates and hospital length of stay. Results: A total of 1,377 radical cystectomies were registered in the public health system in São Paulo, between 2008-2018. A total of 91 institutions performed at least one radical cystectomy in the decade analyzed. The number of radical cystectomies performed per organization during the years analyzed ranged from one to 161. Only 45.6% of patients were operated in organizations that performed more than five radical cystectomies yearly. A total of 684 patients were operated in organizations with higher surgical volume. There were 117 in-hospital deaths, representing an 8.5% mortality rate for the state of São Paulo during the last decade. Whereas highest volume organizations (>6 radical cystectomies/year) had a mortality rate of 6.1%, the lowest volume (<1 radical cystectomy / year) had a 17.5% in-hospital mortality rate. Conclusion: There was a strong relation between organization volume of radical cystectomy and in-hospital mortality rate after radical cystectomy in São Paulo from 2008-2018. Unfortunately, we could not observe a trend toward centralization of such complex procedures, as it has occurred in developed countries during the last decades.
Objective: To examine epidemiologic, anthropometric and clinical variables associated with stress urinary incontinence in obese women, before and after bariatric surgery, and to identify predictive factors of stress urinary incontinence resolution. Methods: Prospective observational study with women enrolled in a bariatric surgery program between 2015 and 2016. Patients were assessed prior to and 6 months after bariatric surgery using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Patient Global Impression of Improvement and the Visual Analogue Scale. Patient assessment also included physical examination and bladder stress tests. Results: A total of 43 women completed the study. There was a 72.7% reduction in stress urinary incontinence (p=0.021). Predictive factors for preoperative diagnosis of stress urinary incontinence included age (p=0.024) and abdominal waist circumference (p=0.048). Urinary symptoms improved after weight loss, especially nocturia (p=0.001) and stress urinary incontinence (p=0.026). Menopause was the most significant predictive factor for persistence of stress urinary incontinence within six months of bariatric surgery (p=0.046). Self-reported outcomes and scores obtained in the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Patient Global Impression of Improvement and the Visual Analogue Scale were associated with significant improvement (p=0.012, p=0.025, and p=0.002 respectively). Conclusion: Older women with larger waist circumference have a higher risk of developing stress urinary incontinence prior to bariatric surgery. Menopausal women are highly prone to persistent stress urinary incontinence, even after weight loss. Weight loss achieved through bariatric surgery improved stress urinary incontinence symptoms and mitigated related impacts on quality of life in the vast majority of women.
Aims To compare 300 U versus 500 U of abobotulinumtoxinA (ABO) intravesical injections for the treatment of idiopathic overactive bladder (OAB) refractory to first and second‐line treatments. Methods A prospective, randomized, single blind study was performed in female patients with symptoms of OAB, who had failed conservative treatment. Patients were treated with 300 or 500 U of ABO injected into 30 sites, avoiding the trigone. All treatments were evaluated by voiding diary, ICIQ‐OAB questionnaire, urodynamic test, visual analogue scale (VAS) for treatment satisfaction and patient global impression of improvement (PGI‐I). The primary outcome was change in maximum cistometric capacity (MCC). Secondary outcome included changes in urgency, complete continence, subjective success (VAS and PGI‐I), and adverse events (urinary retention, UTI, and CIC). Results Twenty‐one patients were included. MCC has increased from 185.0 to 270.9 mL (300 U) and from 240.8 to 311.7 mL (500 U), comparing the baseline with 12 weeks, without statistical difference between the groups (P = 0.270). At 12 weeks, 91% of patients were dry in both groups. At 24 weeks, episodes of incontinence had returned in 50% (300 U) and 0% (500 U) (P = 0.013). Patients were better or much better (PGI‐I) in70% (300 U) and 88.9% (500 U) at 12 w; and 50% (300 U) and 100% (500 U), at 24 w (P = 0.027). The peak of PVR was at 4 w, being 71.7 mL (300 U) and 96.5 mL (500 U). General UTI incidence was 35.7%. One patient (500 U) required CIC for 2 weeks. Conclusions Intravesical ABO injection at 500 U improves symptoms and quality of life for longer period of time than 300 U for idiopathic OAB.
