The authors have studied 5 patients with syringocele--or cystic dilatation of the excretory ducts in Cowper's glands--using a 7.5 MHz linear high-definition US probe. The urethra was distended with a saline solution introduced through a small Foley's balloon catheter placed in the navicular fossa. Longitudinal and transverse scans were employed at both the penis and the perineal region. The syringocele appears on US scans as a tubular image at the bulbous urethra, parallel to the urethral canal, with a "double tube" appearance. It is easily differentiated from urethral stenosis, while it may be confused with congenital urethral duplication, which is extremely uncommon. US with a small-part probe can be considered an useful imaging technique and a valid alternative to conventional radiology, especially in young patients, to avoid high dose exposure.
作者使用7.5MHz线性高清超声探头研究了5例患有尿道球腺囊肿（即尿道球腺排泄管的囊性扩张）的患者。通过置于舟状窝的小Foley气囊导管向尿道内注入生理盐水使其扩张。在阴茎和会阴区域进行纵向和横向扫描。尿道球腺囊肿在超声扫描中表现为球部尿道的管状图像，与尿道管平行，呈“双管”外观。它很容易与尿道狭窄区分开来，不过可能会与极为罕见的先天性尿道重复畸形相混淆。使用小部件探头的超声可被视为一种有用的成像技术，是传统放射学的有效替代方法，尤其是对于年轻患者，可避免高剂量辐射暴露。
