Predicting negative ureteroscopy for stone disease – Minimizing risk and cost

Archivio Italiano di Urologia e Andrologia (2021)

Miguel Eliseu Roberto Jarimba Pedro Moreira Pedro Simões Paulo Temido

Urolithiasis is common worldwide, with ureteric stones being a particular burden. Ureteroscopy (URS) is one of the most useful procedures in treating ureteric stones not passed spontaneously; this procedure has a complication risk of 4%. Negative URS, with described rates up to 15%, represents an avoidable patient risk and use of medical resources.To describe rates and identify predictive factors for negative URS and to define strategies which would minimize patient and financial burden from these unnecessary procedures.A retrospective cohort study analyzed patients who underwent URS in our Center to treat ureteric stones over a period of 2 years. Patient age, gender, and comorbidities, as well as laboratory and imaging findings, were analyzed.262 patients underwent URS for ureteric stones. The female population was 50.8% with a mean age of 56.89 years. A total of 78 (29.8%) URS procedures were negative. Univariate analysis showed a higher prevalence of negative URS in female patients, as well as in primary, smaller, and radiolucent stones. At multivariate analysis, a logistic regression model correctly classified 76% of patients, with smaller stone size and radiolucency being significant predictors of negative URS.Our Center showed a high rate of negative URS, higher than commonly described in the literature. Female patients tend to have an even higher rate, possibly due to unnoticed passage of stones. Patients with small, radiolucent stones showed the highest rates of negative URS.

Mechanisms of male infertility in autosomal dominant polycystic kidney disease

Acta Urológica Portuguesa (2014)

V. Grenha Bruno Jorge Pereira E. Retroz Humberto Eustáquio Coelho Ricardo Godinho

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most prevalent inherited disorders in the world. It's a systemic disease with preferential renal involvement. However, many other organs can be affected, causing important morbidity. Some cases of male infertility are described in literature. That seems to be related to abnormalities in spermatozoa tail microtubules, atonicity and dilatation of seminal vesicle or distal seminal tract cysts and anomalies associated with chronic renal failure. This article presents a patient who combines the two major mechanisms described in literature for male infertility in ADRKD: immotile spermatozoa and megavesicles. This coincidence supports the idea of a common etiological factor to kidney and infertility anomalies. © 2014 Associação Portuguesa de Urologia. Published by Elsevier España, S.L.U. All rights reserved. A Doença Renal Poliquística Autossómica Dominante (DRPAD) é uma das doenças hereditárias mais prevalentes no mundo. Trata-se de uma doença sistémica com envolvimento renal preferencial. No entanto, outros orgãos podem ser afetados, causando morbilidade importante. Alguns casos de infertilidade são descritos na literatura e parecem estar relacionados com alterações nos microtúbulos da cauda do espermatozóide, com atonia e dilatação das vesículas seminais ou quistos do trato seminal distal bem como anomalias relacionadas com doença renal crónica. Este artigo apresenta um doente que combina dois mecanismos major de infertilidade na DRPAD: espermatozóides imóveis e megavesículas. Esta coincidência aponta para a ideia de uma etiologia comum entre as anomalias renais e da infertilidade. © 2014 Associação Portuguesa de Urologia. Publicado por Elsevier España, S.L.U.

Arterioureteral fistula: an unusual clinical case

BMJ Case Reports (2016)

Hugo Coelho Maria José Freire P. Azinhais Paulo Temido

Arterioureteral fistulas (AUFs) are abnormal communications between a major artery and the mid to distal ureter. It is a rare but potentially life-threatening condition that is seldom recognised. We present a case of a 66-year-old man who was admitted to the surgical ward owing to infection of an aortic bifemoral bypass graft. During admission, the patient developed persistent haematuria with considerable loss of haemoglobin. He was submitted to urgent surgical exploration of the graft. An ascending pyelography performed at the beginning of the surgery clearly shows a communication between the left ureter and the vascular graft. Open surgical exploration was undertaken, the fistulised section of the ureter resected and an end-to-end ureteroplasty was performed. The vascular graft was removed and the patient later submitted to left supracondylar amputation. Urinary drainage remained intact.

Tumor dos Cordões Sexuais Não Classificável do Testículo

Acta Médica Portuguesa (2014)

V. Grenha Paula Serra Hugo Coelho E. Retroz Paulo Temido

O tumor dos cordões sexuais não classificável do testículo é um tumor extremamente raro, particularmente na idade adulta. Caracteriza-se histologicamente pela conjugação inespecífica de elementos estromais e epiteliais do testículo, com grau de diferenciação variável. A sua abordagem consiste na orquidectomia radical, geralmente realizada antes do diagnóstico, e posterior vigilância clínica e imagiológica. A literatura disponível sobre esta patologia baseia-se quase exclusivamente na descrição de casos clínicos. O nosso objetivo é apresentar o caso de um doente de 37 anos com um tumor dos cordões sexuais não classificável do testículo, o primeiro descrito em Portugal, e fazer uma revisão da literatura sobre o tema.Palavras-chave: Neoplasias Testiculares; Tumores do Estroma Gonadal e dos Cordões Sexuais.

Endocrine approach in gender dysphoria: the experience in a reference centre

Revista Portuguesa de Endocrinologia Diabetes e Metabolismo (2019)

Diana Martins Margarida Bastos Sandra Paiva Carla Baptista Lígia Fahl Fonseca

Introduction: Gender dysphoria (GD) is characterized by a marked discordance between the psychological perception of individual sex and the biological phenotype.In the present article, the authors aimed to analyze the clinical data of a cohort of subjects diagnosed with GD, referred to a national unit, specialized in the endocrine, psychiatric and surgical treatment of this entity.Methods: Data about demographics and response to treatment, were retrospectively analysed in 85 subjects diagnosed with GD, who were observed in the Endocrinology Consultation, during a 12-year period.Results: It was verifi ed that among 85 patients included in the study, 38 (44.7%) were transgender females and 47 (55.3%) were transgender males.The number of patients seeking treatment substantially increased in the last 5 years, with an inferior age of referral in transgender males.Sixty-three patients (74.1%) started cross-sex hormone therapy, deprived of signifi cant adverse events, and gender affi rming surgery was performed in 25 patients (29.4%). Conclusion:Our study revealed a progressively growing number of patients seeking sexual reassignment, being predominantly transgender males.The majority of subjects started hormone therapy without substantial related adverse events, corroborating that it may be considered as a relatively safe treatment.Gender affi rming surgery was performed in a reasonable number of patients, which was comparable with the experience of other centers.
