Testicular microlithiases are calcite concretions in the convoluted seminiferous tubules lumen. Their ultrasound aspect is a hyper-echogenous area without any shadow in the testicular parenchyma. Their size is smaller than 2mm and there are more than 5. The surface of the gland is respected. Their incidence is about 5% which more important than the incidence of TGT. The association between testicular microlithiasis and TGT has been initially established by retrospective studies but has never been confirmed by recent prospective studies. Their rate is higher for patients with TGT risk factors (cryptorchidism, intratubular germ cell neoplasia and family history). There are not any official guidelines about the management of testicular microlithiasis. An individual screening depending on the clinical situation can be performed: it could be a simple self examination, ultrasound, or testicular biopsies.
睾丸微石症是曲细精管管腔内的方解石凝结物。其超声表现为睾丸实质内的高回声区,无任何阴影。其大小小于2毫米,数量超过5个。睾丸表面未受影响。其发生率约为5%,高于睾丸生殖细胞瘤(TGT)的发生率。睾丸微石症与TGT之间的关联最初是通过回顾性研究确立的,但最近的前瞻性研究从未证实过。有TGT危险因素(隐睾、管内生殖细胞瘤和家族史)的患者其发生率更高。目前尚无关于睾丸微石症管理的官方指南。可根据临床情况进行个体化筛查:可以是简单的自我检查、超声检查或睾丸活检。
