Resumo: | Objectives: To evaluate urinary stone composition in our institution, its gender and age, including variations and the evolution in the last 7 years. Material and Methods: The authors reviewed all urinary stone analysis performed since January 2009 to September 2015 in our hospital – Centro Hospitalar do Tâmega e Sousa, Penafiel, Portugal. Patients were stratified by gender, age and stone composition analyzing the evolution of stone composition in different years. The stone analysis method was infrared spectroscopy. Results: From 302 valid stone analysis reports, 55,3% were female and 44,7% were male patients. Mean patient age was 51±14 years old. A total of 7 different mineral components were identified. 51,6% (n=156) of all the stones had Calcium Oxalate, 41% (n=124) had Calcium Phosphate (33% of Apatite form), 37,7% (n=114) had Uric Acid, 22,1% (n=67) had Ammonium Urate, 9,6% (n=29) had Magnesium Ammonium Phosphate, 6,3% (n=19) had Sodium Urate, and 1,3% (n=4) had Cystine in its composition. Only 30,4% of stones had a single chemical compound. Of these 56% were pure stones of Calcium Oxalate, and 31% were pure stone of Uric Acid. The most frequent mixed stone was Calcium Oxalate + Calcium Phosphate (Apatite) followed by Uric Acid + Ammonium Urate comprehending 45% and 27% of all mixed stones respectively. Related to the ethology we divided stones into 3 groups, pure non-infection, pure infection, and mixed with component of infection, and the prevalence was 37,7%, 4,3% and 57,9% respectively. The distribution between genders was similar and the highest difference was in the Ammonium Urate compound with 28% prevalence in male and 17% in women. (p=0,379) Patients after 50 years old had more prevalence of Uric Acid component accounting for 49% of their stones.(p<0,001) . Along the 7 years of study we identified a significant reduction in the prevalence of mixed stones with component of infection, gradually decreasing from 89,6% in 2009 to 27% in 2015. Conclusions: Calcium Oxalate calculus were the most prevalent, but this difference was not as important as in other studies worldwide. This study highlights the importance of the development of National and European database to report all regional stone composition variations. |

Material e métodos: Os autores reviram todas as análises de cálculos realizadas no Centro Hospitalar do Tâmega e Sousa-Penafiel, desde Janeiro de 2009 a Setembro de 2015. Os doentes foram estratificados por género e idade. Foi analisada a evolução da composição dos cálculos ao longo dos anos. Os cálculos foram analisados usando espectroscopia de infravermelhos. Resultados: Das 302 análises válidas, 55,3% dos doentes eram mulheres e 44,7% eram homens. A idade média dos doentes foi 51 ± 14 anos. Foram identificados 7 compostos minerais diferentes. 51,6% (N=156) continham Oxalato de Cálcio, 41% (N=124) Fosfato de Cálcio (33% em forma de Apatite), 37,7% (N=114) Ácido Úrico, 22,1% (N=67) Urato de Amónio, 9,6% (N=29) Fosfato Amónio Magnésio, 6,3% (N=19) Urato de Sódio e 1,3% (N=4) continham Cistina na sua composição. Apenas 30,4% dos cálculos eram constituídos por um único componente químico. Destes, 56% eram cálculos puros de Oxalato de Cálcio e 31% eram cálculos puros de Ácido Úrico. Os cálculo mistos mais frequentes foram Oxalato de Cálcio + Fosfato de Cálcio (Apatite) seguido de Ácido Úrico + Urato de Amónio compreendendo respectivamente 45% e 27% de todos os calculos mistos. Relativamente à etiologia, os cálculos foram divididos em 3 grupos: Não infeccioso, Infeccioso e Misto (com componente não infeccioso e infeccioso), e a prevalência foi 37,7%, 4,3% e 57,9% respectivamente. A composição foi semelhante em ambos os géneros , sendo a principal diferença nos cálculos de Urato de Amonio com uma prevalência de 28% em homens e 17% em mulheres (p=0,379) Os doentes com mais de 50 anos apresentaram uma maior prevalência de cálculos com Ácido Úrico que correspondeu a 49% dos seus cálculos. (p<0,001) Ao longo dos 7 anos do estudo verificou-se uma redução da prevalência de cálculos mistos com componente de infeção com uma diminuição gradual desde 89,6% em 2009 para 27% em 2015. Conclusões: Os cálculos de Oxalato de Cálcio foram os mais prevalentes, no entanto esta diferença não foi tão significativa como em outros estudos. Este estudo realça a existência de diferenças regionais significativas na composição dos cálculos e aponta para a importância do desenvolvimento de registos nacionais e internacionais de composição dos cálculos urinários.Associação Portuguesa de Urologia2017-12-16T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.24915/aup.34.3-4.17oai:oai.actaurologicaportuguesa.com:article/17Acta Urológica Portuguesa; Vol. 34 No. 3-4 (2017): july-september; october-december; 7-12Acta Urológica Portuguesa; v. 34 n. 3-4 (2017): julho-setembro; outubro-dezembro; 7-122387-04192341-4022reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttp://www.actaurologicaportuguesa.com/index.php/aup/article/view/17https://doi.org/10.24915/aup.34.3-4.17http://www.actaurologicaportuguesa.com/index.php/aup/article/view/17/22Valente, PedroCastro, HélderPereira, InêsVila, FernandoAraújo, PauloVivas, CristinaSilva, AnaOliveira, AnaLindoro, Joaquiminfo:eu-repo/semantics/openAccess2022-09-21T09:04:45Zoai:oai.actaurologicaportuguesa.com:article/17Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:55:52.194911Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
