Abstract

Abstract: This systematic review was conducted in accordance with the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, including clinical studies in which one of the outcomes was semen parameter improvement after varicocele embolization using coils only. The objective of the review was to assess the evidence on the role of embolization using coils alone for semen parameter improvement in men with varicocele, since embolization using coils is the most cost-effective method of varicocele repair. Study quality was assessed using the methodological index for non-randomized studies (MINORS). Out of six retrospective and two prospective observational or comparative clinical studies involving 701 patients, semen concentration improved significantly in all five studies that assessed this parameter. Mean semen motility improved significantly in seven studies. The impact of embolization on semen density could not be analyzed.

Resumo

Resumo: Trata-se de uma revisão sistemática conduzida de acordo com o PRISMA 2009 (Principais Itens para Relatar Revisões Sistemáticas e Metanálises) que incluiu estudos em que a melhora dos parâmetros seminais tenha sido um dos desfechos. Esta revisão foi realizada com o objetivo de avaliar as evidências sobre o papel da embolização com uso apenas de molas na melhora de parâmetros seminais em homens com varicocele, uma vez que a embolização apenas com molas é o método com melhor custo-benefício para o reparo de varicoceles. A qualidade dos estudos foi analisada com o índice MINORS. Em seis estudos clínicos retrospectivos e em outros dois prospectivos observacionais ou comparativos, a concentração seminal melhorou significativamente em todos os cinco estudos que avaliaram esse parâmetro. A motilidade seminal melhorou significativamente em sete estudos. Não foi possível analisar o impacto da embolização com molas na densidade seminal.
