经直肠超声对前列腺苗勒管囊肿与射精管囊肿的鉴别诊断价值

Differential diagnostic value of transrectal ultrasonography for mullerian cyst and ejaculatory duct cyst

目的探讨经直肠超声（Transrectal ultrasonography，TRUS）在苗勒管囊肿（Mullerian ductcyst，MDC）与射精管囊肿（Ejaculatory ductcyst，EDC）鉴别诊断中的价值。方法收集TRUS所见前列腺中线囊肿70例，其中48例进行手术或超声引导下穿刺，与病理结果对照，回顾性分析其声像图特征。结果70例病例中，苗勒管囊肿18例，射精管囊肿30例，不能明确性质22例。其中EDC伴有精囊扩张16例，射精管扩张4例，输精管扩张2例，精囊炎7例。结论TRUS在MDC与EDC的鉴别诊断中有一定的临床价值。

Objective To investigate the differential diagnostic value of the transrectal uhrasonography （TRUS） for mullerian duct cyst （MDC） and ejaculatory duct cyst （EDC） .Methods Collect 70 cases with midline prostatic cyst diagnosed by TRUS, 48 cases of which underwent surgery or ultrasound-guided puncture .Com- pared the TRUS results with pathological results.Retrospectively analyzed the features of TRUS. Results In the 70 patients, 18 were diagnosed as mllerian duct cyst, 30 ejaculatory duct cyst 30 cases and the other 22 cases properties unknown;In the cases of EDC , 16 were seminal vesicle expansion, 4 ejaculatory duct expansion , 2 vas deferens expansion , and 9 seminal vesieulitis. Conclusion TRUS has certain clinical value in differential diagnosis of MDC and EDC.
