Background: Transrectal ultrasonography (TRUS) examinations have been applied in the prostate, urinary bladder, and distal ureter. During TRUS, color Doppler imaging (CDI) has been used as an adjunct to the conventional gray-scale ultrasonography for improving the accuracy of prostate cancer detection, especially for isoechoic cancers. In addition to the prostate cancer, CDI may also provide important information in the diagnosis of various diseases in prostate, urinary bladder, and distal ureter.
Purpose: The purpose of this exhibition is to provide pictorial review of the CDI during TRUS in various disease of the prostate, urinary bladder, and distal ureter.
Image findings: This exhibition consists of the followings: introduction / prostatic adenocarcinoma / prostatic transitional cell carcinoma / granulomatous prostatitis / prostatic tuberculosis / acute prostatitis / prostatic abscess / bladder tumor / malignant distal ureteral stricture / benign distal ureteral stricture / summary.
Conclusion: CDI may provide useful information in the diagnosis of the various disease of the prostate, urinary bladder, and distal ureter.
