102例经直肠超声引导活检前列腺癌声像图分析
Analysis on Sonograms of 102 Patients with Prostate Carcinoma by Transrectal Ultrasound Guided Biopsy
摘要
Abstract
Objective To study the ultrasonographic features of the prostate carcinoma and improve the positive rate of prostate biopsy. Method The patients who had either serum PSA>4 ng/Ml or abnormal findings of digital rectal examination underwent transrectal ultrasound guided biopsy and the biopsy samples were respectively marked. 102 patients with prostate carcinoma proved by pathology were studied by comparison between the pathology and ultrasonography. Results Among the 102 patients, 38 cases (37%) had no significant abnormal ultrasonography, 26 cases (25%) were detected with nodes, 30 cases (29 %) displayed nonuniform and unborder between the peripheral zone (PZ) and transitional zones (TZ) , another 8 cases (8%) were detected low- echo masses. Color Doppler imaging showed normal in 75 cases, flows gathering or passing round at the node in 8 cases, widespread increasing in 10 cases and decrease in 9 cases. The sensitivity value of ultrasonography and color Doppler imaging respectively were 63% (64/102) and 26% (27/102). Conclusions The prostate carcinoma is highly doubted in the case of following ultrasonographies: low- echo- node in the peripheral zone; unclear border; transitional zone; low-echo mass of the prostate and the nodes of the prostate where color flow gather or pass round. These are the focal point of prostate needle biopsy.关键词
