The symptoms of prostatic and periprostatic cysts are nonspecific and digital rectal examination has no definite findings detected. The conventional radiological plain film cannot define the relationship of a cyst to the surrounding structures. The use of MRI as a means in detection is too expensive. To solve these problems, we detected 118 cysts in 73 patients by transrectal ultrasound (TRUS) and discussed the TRUS imaging findings of various prostate and periprostate cysts with illustrations from our clinical practice. We suggest that TRUS can be used routinely, because its distinct advantage of high resolution for minute nodular or cystic lesion detection with high quality image demonstrates the relationship of surrounding structures, and provides an outstanding novel diagnostic modality.
前列腺及前列腺周围囊肿的症状不具有特异性，直肠指诊也未发现明确体征。传统的放射学平片无法明确囊肿与周围结构的关系。使用磁共振成像（MRI）进行检测成本过高。为了解决这些问题，我们通过经直肠超声（TRUS）对73例患者的118个囊肿进行了检测，并结合临床实践中的病例展示，探讨了各种前列腺及前列腺周围囊肿的TRUS影像学表现。我们建议可常规使用TRUS，因为它在检测微小结节或囊性病变方面具有高分辨率的显著优势，能提供高质量图像，显示周围结构的关系，是一种出色的新型诊断方法。
