Magnetic resonance imaging and clinical findings in seminal vesicle pathologies

ABSTRACT Purpose Congenital and acquired pathologies of the seminal vesicles (SV) are rare diseases. The diagnosis of SV anomalies is frequently delayed or wrong due to the rarity of these diseases and the lack of adequate evaluation of SV pathology. For this reason, we aimed to comprehensively evaluate SV pathologies and accompanying genitourinary system abnormalities. Materials and Methods Between March 2012 and December 2015, 1455 male patients with different provisional diagnosis underwent MRI. Congenital and acquired pathology of the SV was identified in 42 of these patients. The patients were categorized according to their SV pathologies. The patients were analyzed in terms of genitourinary system findings associated with SV pathologies. Results SV pathologies were accompanied by other genitourinary system findings. Congenital SV pathologies were bilateral or predominantly in the left SV. Patients with bilateral SV hypoplasia were diagnosed at an earlier age compared to patients with unilateral SV agenesis. There was a significant association between abnormal signal intensity in the SV and benign prostate hypertrophy (BPH) and patient age. Conclusion SV pathologies are rare diseases of the genitourinary system. The association between seminal vesicle pathology and other genitourinary system diseases requires complete genitourinary system evaluation that includes the seminal vesicles.

Ocorrência de infecção do trato urinário em cobradoras de ônibus / Occurrence of urinary tract infection in a bus servicer

JUSTIFICATIVA E OBJETIVOS: As infecções do trato urinário (ITU) são diversas manifestações clínicas que variam desde a presença assintomática de bactérias na urina até infecção renal grave, resultando em sepse, situação que poderá levar o paciente ao óbito. A principal estratégia de defesa do hospedeiro é um fluxo urinário desobstruído, que dificulta o percurso da bactéria ascendente. O objetivo deste estudo foi verificar a ocorrência de sintomas sugestivos de ITU, descrevendo as atividades diárias que levam à sua maior suscetibilidade, bem como identificar os fatores predisponentes presentes e verificar os principais sintomas clínicos obtidos. MÉTODO: Realizou-se estudo exploratório, descritivo e prospectivo. A população constituiu-se de 100 mulheres selecionadas de acordo com a faixa etária (30 a 40 anos) e função empregatícia como cobradora de ônibus. RESULTADOS: Os resultados demonstram que 50% das entrevistadas apresentaram ocorrência de ITU, 55% alegaram recidivas; o sintoma mais frequente foi dor pélvica (80%), associada ou não ao ato de urinar e que 95% das mulheres relataram estase urinária. CONCLUSÃO: É possível que orientações mais adequadas referentes a hábitos alimentares saudáveis possam melhorar a qualidade de vida e prevenir doenças específicas deste grupo.

BACKGROUND AND OBJECTIVES: Urinary tract infections (UTI) are different clinical manifestations ranging from asymptomatic presence of bacteria in the urine up to serious kidney infection, resulting in sepsis, which could lead the patient to death. The main host defense is a clear urine flow, which makes the route of the bacterium ascendant. This study aimed to verify the occurrence of UTI, describing the daily activities that lead to increased susceptibility to UTI, identify predisposing factors present among the participants and further important clinical symptoms mentioned. METHOD: Carried out an exploratory, descriptive and transversal. The study population consisted of 100 women selected according to age (30 to 40 years) and employment-function. RESULTS: The results show that 50% of respondents reported the occurrence of UTI, 55% reported recurrence; the most frequent symptom was pelvic pain 80%, with or without the act of urinating and that 95% of women report urinary stasis. It was concluded that due to his professional activity, the collectors had a favor to bacterial growth. CONCLUSION: It is possible that appropriate policies relating to healthy habits can improve the quality of life and prevent specific diseases of this group.

Patología nefrourológica en niñas con síndrome de Turner / Nephrourologic pathology in girls with Turner syndrome

Las malformaciones nefrourológicas en el síndrome de Turner son frecuentes, por lo que su diagnóstico y seguimiento son importantes para disminuir la morbilidad de esta entidad. El objetivo de este trabajo retrospectivo fue analizar la patología nefrourológica en 72 niñas con síndrome de Turner atendidas entre 1989 y 2008 en el Hospital Garrahan. La prevalencia de patología nefrourológica fue del 33% (24 pacientes). Predominaron las anomalías del sistema urinario aisladas (10 pacientes, 42%) o asociadas a malformaciones renales (9 pacientes, 37%); 5 pacientes (21%) tuvieron anomalías estructurales renales aisladas. El 50% presentó complicaciones (8 infección urinaria, 2 proteinuria y 2 hipertensión arterial).

Nephrourologic malformations in Turner syndrome are frequent, its diagnosis and follow-up is important in order todiminish the morbidity of this disease. The aim of this retrospective study was to analyze the nephrourologic pathologyin 72 girls with Turner syndrome followed between 1989 and 2008 at Garrahan Hospital. The prevalence of nephrourologic involvement was 33% (24 patients). The most frequent findings were urinary system malformations, isolated (10 pacientes,42%) or associated with renal malformations (9 patients, 37%); 5 patients (21%) had only renal malformations. Fifty percent of patients developed complications (8 urinary tractinfection, 2 proteinuria and 2 arterial hypertension); however, none progressed to chronic renal failure. The prevalence of nephrourologic involvement was 33% and a half of these girls developed complications, our findings show the need of routine nephrological follow-up of girls with Turner syndrome and nephrourologic malformations.

Estudio flujo-presión de la micción en el hombre / Fluid pressure study of the micturition in men

Pressure-flow study of voiding is, at present, the best method of analysing voiding function quantitatively. It is an invasive second line study by which the relationship between pressure in the bladder and urine flow is measured during bladder emptying. The main use of it is the evaluation of older men with lower urinary tract symptoms. It allows to differentiate between patients with low urinary flow resulting from poor bladder contractility (low detrusor pressure) and those whose low urinary flow is secondary to true bladder outlet obstruction (high detrusor pressure),as well as combined alterations. In this article we describe the International Continence Society (ICS) nomenclature, the bladder detrusor and urethral functions during voiding, as well as some principles of voiding mechanics. We also discuss the analysis of the results in men with bladder outlet obstruction using the Abrams-Griffiths nomogram, the Schãfer nomogram and the ICS nomogram, including the evaluation of bladder contractility.

Neurofibromatose VI: Aparelhos cardiovascular, digestivo e genitourinário / Neurofibromatosis VI. Cardiovascular system, digestive and genito-urinary tract

Estudamos 11 pacientes portadores de neurofibromatose previamente diagnosticada. Seis pacientes pertenciam ao sexo masculino, quatro eram pardos e três negros. O mais jovem tinha 17 anos e o mais idoso 53. Submetemos os oito pacientes ambulatoriasi a exames clínico, otorrinolaringológico e eletrocardiográfico e os três restantes foram estudados através de suas necrópsias. Os quatro pacientes ambulatoriais do sexo feminino foram submetidos a exame ginecológico
