Relationship of ultrasonographic findings to histology in XXXX .

@entity1 @entity263 @entity5 @entity4623
We compared ultrasonic findings and histology in 25 @entity1 with @entity263 . Ultrasonically guided transperineal biopsy of focal @entity4623 was performed in 19 @entity1 , in @entity263 was suspected. Six of them had two different echogenic areas in the same focal lesion, so a total of 25 echogenic areas were assessed. Fourteen of these 25 areas were hypoechoic. The Gleason score varied, but residual prostatic glands and @entity5 glands with slightly enlarged lumen did not exist. Six of the areas were slightly more echogenic than the above 14 areas, and cribriform @entity5 with slightly enlarged glands occupied the greater part of these specimens. Four of the areas were isoechoic, and they contained residual prostatic glands showing a normal distribution, regardless of the Gleason score or grade of @entity5 infiltration. The only hyperechoic lesion contained numerous tiny areas of calcification. In the 6 @entity1 without focal lesions, the peripheral and transition zones showed a normal echogenicity. Two of these @entity1 had @entity5 in the transition zone, and biopsy showed @entity5 glands with slightly enlarged lumens. In the 4 @entity1 , various-sized @entity5 were seen, but there was a normal distribution of residual prostatic glands and stroma. These results indicated that prostatic echogenicity is determined by the presence of @entity5 glands with enlarged lumina as well as residual prostatic glands and stroma.
