高频超声和3.0T磁共振检查男性淋球菌性尿道旁腺炎的比较

目的 探讨男性淋球菌性尿道旁腺炎的形态特征。 方法 使用Siemens Acuson X300实时超声显像仪和Philips Achieva 3.0T磁共振联合检查11例男性淋球菌性尿道旁腺炎患者。 结果 高频超声影像均表现为管道状回声，境界清，边缘光整，内部呈弱回声，一端为盲端，一端和外界相通。走行方向与尿道平行。管道直径0.7 ~ 1.3 mm（平均1.1 ± 0.2 mm），管道长度7.0 ~ 12.0 mm（平均8.4 ± 0.6 mm）。其中2例管道状回声内见液性暗区。3.0T磁共振检测不到男性尿道旁管。 结论 高频超声能检测出男性淋球菌性尿道旁腺炎的形态特征，为手术治疗提供有价值的超声图像。

Methods Eleven male patients with gonococcal inflammation of paraurethral glands were examined by both real-time ultrasound imaging （Siemens Acuson X300） and 3.0 T magnetic resonance imaging （MRI, Philips Achieva）. Results High-frequency ultrasound imaging revealed tubular echoic areas with well-defined borders and smooth margins in all the patients. The inside of these tubular areas was weak-echoic. These tubular echoic areas were blind in one end, but open in the other end, and ran in parallel with the urethra. The mean lumen diameter was 1.1 ± 0.2 mm （range, 0.7 － 1.3 mm） , and the mean lumen length was 8.4 ± 0.6 mm （range, 7.0 － 12.0 mm）. Anechoic liquid-filled areas were seen in the tubular echoic areas in two patients. Paraurethral ducts were not detected by 3.0 T MRI in these patients. Conclusions High-frequency ultrasound imaging can clearly show the morphologic characteristics of gonococcal inflammation of paraurethral glands in males, and provide valuable ultrasound images for surgery.
