附睾淤积症的超声诊断

2018-09-04 佚名 即时超声

附睾淤积症是输精管结扎术后一种常见的并发症,输精管结扎后,当附睾液的产生、吸收、消除间的动态平衡被打破,精子在附睾管内淤积,附睾管扩张、破裂,精子外渗,间质内发生无菌性炎症及附睾睾丸结构与功能受损,导致附睾淤积症的发生。它是一种较为常见的并发症,原因之一为男性结扎手术引起,之二为输精管阻塞,包括输精管缺如,附睾畸形,附睾炎症,附睾肿瘤等。

病例学习

病史:患者,男,会阴部外伤检查。

超声表现:附睾增大,内可见细密的点状回声,可出现内壁不光整的无回声区,CDFI睾丸及附睾血流无异常改变。

超声诊断:附睾郁积症。









讨论

输精管结扎术是一种简单、经济、安全、有效的男性节育技术,医源性输精管阻断,若合并感染、结扎部位过低、术中损伤精索血管、精索静脉曲张等情况时,附睾液新的动态平衡不能形成,机体产生的精子及附睾液不能被及时吸收淤存在附睾内,引起附睾的阻塞淤积症状。绝大多数患者无临床症状,但少数可出现附睾肿胀,压痛症状,部分患者在用力及性交时有突发附睾部疼痛史。

正常附睾头、体、尾的厚度分别小于1.5m、O.5cm、1.0cm,实质回声均质,而附睾淤积症者附睾厚度增大,实质回声稍増强,可见密集点状回声,呈“麻饼样”改变(图1),部分患者附睾管可显示,呈细小管状回声,CDFI示附睾血流无明显变化,当同时合并有炎症时,附睾肿大较明显,回声不均匀,与周围组织分界模糊。



鉴别诊断

①附睾结核:病程缓慢,疼痛不明显,病灶侧附睾体积增大,附睾头、体、尾常同时累及,呈低回声不均匀结节,内部多见强光斑,部分伴声影,CDFI常无特征性血流信号;

②附睾炎:疼痛较明显,常有急性或反复发作史,附睾肿大,形态不规则,以附睾尾部多见,内部回声不均匀,局部呈结节状,结节内部常无钙化灶,CDFI示病变侧附睾血流增多.

附睾淤积症在超声像上的特征性表现,对此病的诊断与鉴别诊断具有较高的临床运用价值,超声检查具有价廉、无创、诊断率高、操作简单又可多次反复对照等优点,可以作为附睾淤积症首选诊断方法,并可作为输精管吻合术后再通与否的影像检查方法。
