Introdução: O ureter retrocava é uma malformação congênita rara que pode ser causa de uropatia obstrutiva com sintomas inespecíficos como dor lombar e complicações como ureterolitíase e pielonefrite, que normalmente aparecem entre a terceira e a quarta décadas de vida, e exige tratamento cirúrgico na maior parte dos casos. Objetivo: Apresentar um caso de ureter retrocava associado a ureterolitíase e uma revisão da literatura a respeito das técnicas cirúrgicas para sua correção. Relato de caso: Os autores apresentam um caso de ureterolitíase e ureter retrocava, diagnosticado por tomografia computadorizada, em um paciente masculino de 43 anos com dor lombar direita, corrigido através de técnica laparoscópica transperitoneal. Conclusão: A correção cirúrgica laparoscópica do ureter retrocava tem se mostrado benéfica em diversos aspectos quando comparada ao acesso aberto e uma abordagem que ainda não havia sido publicada é a correção do ureter retrocava associado a ureterolitíase num mesmo tempo cirúrgico.

Objective: To present a case of ureterolithiasis and retrocaval ureter and a review of literature, regarding the different types of access for his surgery. Case Report: The authors present a case of ureterolithiasis and retrocaval ureter diagnosed by computed tomography in a 43-year-old male patient with right lower back pain, corrected using a transperitoneal laparoscopic technique. Conclusion: Laparoscopic surgical correction of the retrocaval ureter has shown to be beneficial in several aspects when compared to open access, and one that has not been previously reported is the one-step resolution of the association with ureterolithiasis.Keywords: Retrocaval ureter, Hydronephrosis, Ureterothiasis, Urogenital abnormalities, Laparoscopy
Hemangioendothelioma is a rare vascular tumor whose etiology has not yet been defined. Currently, it is known to affect different sites, such as the abdominal-pelvic cavity. It is also known to present intermediate characteristics to hemangioma and angiosarcoma.In recent studies, 50-76% of patients are asymptomatic. Surgical treatment is indicated in most cases. The authors present a case of hemangioendothelioma with pelvic involvement and initial presentation as acute renal failure due to extrinsic ureteral compression, treated surgically, with histopathological diagnosis of hemangioendothelioma and recurrence after one year of the initial treatment presenting a histologically different form. This case illustrates a rare cause of lower urinary tract symptoms (LUTS), obstructive uropathy and acute renal failure and the appearance of two different tumors within a year, in line with the genetic/immunological factor in its genesis.
Purpose Our objective was to investigate the prevalence of SWA, associated factors, relationship with STIs, and behavioral aspects in men attended at Referral Centers for STIs and acquired immunodeficiency syndrome (AIDS)/CR-STI/AIDS in northeast Brazil. Materials and Methods In this cross-sectional study, a questionnaire with sociodemographic, clinical, sexual and SWA practices information was applied to 400 men attended at two CR-STI/AIDS in Northeast Brazil on the years of 2018 and 2019. Clinical and laboratory diagnoses of STIs were confirmed in medical records. Logistic regression models were performed to identify the independent predictors for SWA. Results The prevalence of SWA over total samples was 15.00%. Of the participants, 239 (59.75%) of the participants were diagnosed with STIs, and of these 37 (15.48%) reported SWA. Most men practiced SWA in adolescence, being the last episode more than 20 years ago, usually with asinine and mules, in vaginal route and without a condom. SWA practitioners have higher percentages of occurrence of some viral STIs. SWA was associated with increasing age, history of residence in a rural area with remained over 12 years, married or widowed/separated, heterosexuals, with less than 7 years of study, Catholics, with hepatitis B, former user of alcoholic beverages and smokers, with a history of STI and intercourse with sex workers. Conclusion SWA practices increase STIs vulnerability. The association between hepatitis B and SWA highlights the importance of educational campaigns and conclusive studies on the topic.
Introdução: O Sarcoma de Kaposi é uma neoplasia rara e sua apresentação isolada no pênis representa 2-3% dos casos. Quase a metade dos pacientes é assintomática e o tratamento mais utilizado é a exérese cirúrgica. Objetivo: Apresentação rara de um sarcoma de kaposi isolado no pênis. Relato do Caso: Paciente de 74 anos em tratamento de Linfoma não Hodgkin e HIV positivo com diagnóstico de sarcoma de kaposi isolado no pênis. Conclusão: O sarcoma de kaposi confinado ao pênis deve ser considerado como diagnóstico diferencial das lesões genitais, principalmente em pacientes com HIV positivo e o tratamento deve ser individualizado. Palavras chave: Sarcoma de Kaposi, Pênis, Câncer de pênis, Imunossupressão, HIV, Linfoma não-Hodgkin ABSTRACTIntroduction: Kaposi’s sarcoma is a rare neoplasm and its isolated presentation in the penis represents 2-3% of cases. Almost half of the patients are asymptomatic and the most used treatment is surgical excision. Objective: Rare presentation of isolated kaposi sarcoma on the penis. Case Report: A 74-year-old patient undergoing treatment for non-Hodgkin’s lymphoma and HIV positive diagnosed with isolated kaposi sarcoma on the penis. Conclusion: Kaposi’s sarcoma confined to the penis should be considered as a differential diagnosis of genital lesions, especially in patients with HIV positive and treatment should be individualized.

ABSTRACT:Introduction: The first reports of renal tumors originated from the renal tubule epithelium date from 1855, Robin, and 1867, Waldeyer. However, at the same era, some pathologists wrong believed these tumors were originated from adrenal gland tissues due to the fat content of the tumor (hypernephroid tumor theory - origin above the kidney, 1894). The first diagnostic test for renal tumor was excretory urography. Over the years, with the emergence of ultrasonography (US), it has been replaced. Nowadays, after the US screening, all renal lesions should be evaluated, in a complementary way, with computed tomography (CT) - gold standard - in the pre-contrast, arterial, portal, nephrographic phases. This is necessary to characterize the presence of enhancement after contrast. A kidney injury that enhances more than 15 Housfield units (UH) is suspected of kidney cell cancer. There are different subtypes of renal tumors derived from various sites of the nephron. Clear cell Renal Cell Carcinoma (RCC) is one of the subtypes that originates from the renal cortex. It is a rare tumor in children. Objective: The aim of this chapter is to review de incidence, pathology, diagnosis and treatment in clear-cell renal carcinoma in pediatric population. Methods: The authors performed a literary review about clear-cell renal carcinoma in pediatric population using Pubmed Database and Campbell-Walsh Urology as source search.Keywords: Renal cell carcinoma, Tumor, Pediatrics, Kidney, Nefrectomy ResumoRESUMO:Introdução: Os primeiros relatos de tumores renais originados do epitélio do túbulo renal datam de 1855, Robin, e 1867, Waldeyer. Contudo, na mesma época, alguns patologistas acreditavam erroneamente que esses tumores provinham dos tecidos das glândulas supra-renais, devido ao teor de gordura do tumor (hypernephroid tumor theory – origem acima do rim, 1894). O primeiro teste diagnóstico para tumor renal foi a urografia excretora. Ao longo dos anos, com o surgimento da ultrassonografia, esse teste foi substituído. Atualmente, após a leitura da ultrassonografia, todas as lesões renais devem ser avaliadas, de forma complementar, com tomografia computadorizada (TC) – padrão ouro – nas fases pré-contraste, arterial, porta e nefrográfica. Isso é necessário para caracterizar a presença de melhora após contraste. Uma lesão renal que aumenta mais de 15 unidades Housfield (UH) é suspeita de câncer de células renais. Existem diferentes subtipos de tumores derivados de vários locais do néfron. O carcinoma de células renais de células claras (CCR) é um dos subtipos originários do córtex renal. É um tumor raro em crianças. Objetivo: O objetivo deste capítulo é revisar a incidência, a patologia, o diagnóstico e o tratamento do CCR na população pediátrica. Método: Os autores realizaram uma revisão literária sobre carcinoma renal de células claras em população pediátrica usando a base de dados PubMed e o livro Campbell-Walsh de Urologia como fonte de pesquisa.Palavras chave: Carcinoma de células renais, Tumor, Pediatria, Rim, Nefrectomia
