ABSTRACT

ABSTRACT Purpose: COVID-19 continues to be an urgent World issue. Receptors of angiotensin converting enzyme 2 (ACE2), gateway of SARS-CoV-2, are present in the lungs, bladder, prostate, and testicles. Therefore, these organs face high risk of damage caused by the virus and this mechanism may explain non-respiratory symptoms of the disease. Materials and Methods: This systematic review, guided by the PRIMSA statement, was proposed to elucidate possible urological complications of COVID-19. Searches were carried out in Medline (PubMed), Cochrane (CENTRAL), Embase, MedRxiv and LILACS. Bias analysis was made using the specific Newcastle-Ottawa Scale for each study design. Results: Search was carried out until April 2022, and 8,477 articles were identified. Forty-nine of them were included in this systematic review. There is evidence that lower urinary tract symptoms and acute scrotum may be signs of COVID-19 in men, although in a small proportion. Also, the disease may have a transitory impact on male fertility, evidenced by several alterations in sperm counts. However, it must be clarified whether this impact is transitory, or may last for longer periods. Several patients showed reduction of total value of testosterone. Two authors linked low levels of testosterone with worse outcomes of COVID-19, suggesting that the hormone may be used as an early biomarker of the severity of the disease. Moreover, it is extremely unlikely that SARS-CoV-2 is transmitted by semen. Conclusion: This systematic review identified possible repercussions of COVID-19 in the urinary as well as in the male reproductive system.

ABSTRACT

Hemangioperycytoma is a rare perivascular tumor that seldom involves the urogenital system. This tumor often appears with an unspecific clinical picture, and sometimes is associated with hematuria or hypertension. Diagnosis is based on a combination of histological and immunohistological findings. We report a case of a 52-year-old patient with renal hemangiopericytoma who underwent surgical treatment at our service. This report also includes a literature review on the subject.


Hemangiopericitoma é um raro tumor perivascular que raramente envolve o sistema urogenital. Esses tumores geralmente se manifestam com quadro clínico inespecífico, por vezes associado a hematúria ou hipertensão. O diagnóstico baseia-se numa combinação de alterações histológicas e imuno-histológica. Este artigo relatou o caso de uma paciente de 52 anos de idade com um hemangiopericitoma renal submetida a tratamento cirúrgico em nosso serviço e incluiu uma revisão de literatura sobre o assunto.

ABSTRACT

Small cell carcinoma of the urinary bladder is an extremely aggressive and rare tumor. Even though small cell carcinoma most commonly arises from the lungs there are several reports of small cell carcinoma in extrapulmonary sites. Due to its low frequency there is no well-established management for this disease. We report the case of a 61 year-old man with small cell carcinoma of the bladder who underwent radical cystectomy following neoadjuvant chemotherapy. We also reviewed the literature for the optimal treatment strategy.


O carcinoma de células pequenas da bexiga urinária é um tumor extremamente agressivo e raro. Apesar desses tumores terem como sítio principal o pulmão, existem diversos relatos de carcinoma de pequenas células extrapulmonares. Pela baixa frequência, ainda não existe um tratamento bem estabelecido para essa neoplasia. Relatamos o caso de um homem de 61 anos de idade com carcinoma de células pequenas da bexiga urinária que foi submetido à quimioterapia neoadjuvante seguida de cistectomia radical. Fazemos ainda revisão na literatura em busca dos métodos de maior sucesso para o tratamento.

ABSTRACT

O câncer de bexiga é um importante problema de saúde mundial, tanto pelas elevadas taxas de prevalência, quanto pelos custos relacionados ao tratamento. Desde a introdução da imunoterapia intravesical adjuvante com bacilo Calmette-Guérin, vem sendo observada diminuição na taxa de recorrência. As principais complicações são de pequeno porte e simples resolução a partir de medidas locais e orientações. A bexiga contraída, uma complicação local rara e grave, mas incapacitante em alguns casos, é observada principalmente em doentes com um programa de manutenção. Relatamos aqui o caso de um paciente masculino submetido a ressecção transuretral da bexiga por um carcinoma urotelial T1 de alto grau, que desenvolveu tal complicação durante tratamento com bacilo Calmette-Guérin, sendo portanto submetido à cistoprostatectomia com realização de neobexiga ortotópica ileal.


Bladder cancer is an important health problem worldwide due to high prevalence rates and costs related to treatment. A reduction in recurrence rates has been observed since the introduction of adjuvant intravesical immunotherapy with bacillus Calmette-Guerin. There are mild complications that are easily solved by local measures and orientations. Bladder contracture, a rare and severe local complication, in some cases leading to disability, is observed primarily in patients in a maintenance program. In this article we reported the case of a male patient who underwent transurethral resection of the bladder because of a high-grade T1 urothelial carcinoma and developed this complication during treatment with bacillus Calmette-Guerin. For this reason he was submitted to cystoprostatectomy with orthotopic ileal neobladder reconstruction.

ABSTRACT

Objectives: To experimentally evaluate the efficacy of a standard sterilization protocol employed during reuse of disposable helical stone baskets. Methods: Study performed on 20 helical stone baskets: 10 were used in the initial validation process, contaminated with Escherichia coli ATCC 25922 and imprinted on Müeller-Hinton media; 10 catheters were contaminated with Geobacillus stearothermophilus ATCC 7953, processed, inoculated in TSB and incubated in a water bath at a temperature of 55ºC. Bacterial growth was evaluated after 1, 3, 5 and 7 days. After sterilization, stone baskets were also opened and closed 40 times to check for functional problems. All plastic and basket parts were carefully checked for damages. Results: After the 72-hour incubation period, there was growth of E. coli ATCC 25922 in 100% of imprints. After the sterilization process and up to 7 days incubation period on a blood agar plate, there was no growth of G. stearothermophilus ATCC 7953 or any other bacteria. There were no functional problems or damage to baskets after the sterilization process. Conclusion: The ethylene oxide system is efficacious and safe for sterilization of disposable helical stone baskets. However, further clinical studies are required and should provide more safety information.


Objetivo: Avaliar experimentalmente a eficácia de um protocolo padrão de esterilização de cestas helicoidais descartáveis extratoras de cálculo. Métodos: Estudo realizado com 20 cestas helicoidais descartáveis extratoras de cálculo: 10 foram utilizadas no processo inicial de validação do método, contaminadas com Escherichia coli ATCC 25922 e semeadas em meio de Müeller-Hinton; 10 foram contaminadas com Geobacillus stearothermophilus ATCC 7953, processadas, inoculadas em TSB e incubadas em banho maria, a 55 ºC. O crescimento bacteriano foi avaliado depois de 1, 3, 5 e 7 dias. Após a esterilização, as cestas helicoidais descartáveis extratoras de cálculo foram abertas e fechadas 40 vezes para avaliar problemas funcionais. Todas as partes plásticas foram avaliadas quanto a danos. Resultados: Após as 72 horas de incubação, observou-se crescimento de E. coli ATCC 25922 em todos os meios. Após a esterilização e até 7 dias de incubação, não houve crescimento de G. stearothermophilus ATCC 7953 ou de qualquer outra bactéria. Não foram observados problemas funcionais ou danos nas cestas após a esterilização. Conclusão: O processo de esterilização com óxido de etileno é seguro e eficaz para re-esterilizar cestas helicoidais descartáveis extratoras de cálculo descartáveis. Contudo, são necessários mais estudos clínicos para fornecer mais informações sobre segurança.

ABSTRACT

Foram analisados os aspectos epidemiologicos e clinicos observados em 200 pacientes com trauma abdominal a atendidos no Hospital das Clinicas de Botucatu(SP). O grupo mais acometido e constituido de jovens do sexomasculino. Os ferimentos ocorreram em 109 pacientes (54,5%) e as contusoes em91 (45,5%). Contrariamente ao observado nas grandes cidades, em Botucatu a causamais importante do ferimento abdominal foi a arma branca (35%), seguida das lesoes determinadas por projeteis de arma de fogo (18,5). No trauma abdominal fechado o acidente por veiculo a motor apresentou o maior numero de vitimas. A mortalidade operatoria foi mais elevada na contusao (11%) do que no ferimento (37%)As causas determinantes desta diferença sao as associaçoes com lesoes extra-abdominais (cranio, torax e esqueleto ) e a demora na indicaçao cirurgica, fatos observados no trauma fechado. A mortalidade operatoria globas foi de 7%
