Abstract
A previous autopsy study correlated the histopathological type of BPH with the ultrasonotomographic pattern, so we could estimate 78.3 % of the Glandular type as hypoechoic pattern of echogenesity, 77.8 % of the Fibromyomatous type as hyperechoic, and 75.0 % Mixed type as isoechoic. The purpose of the present study was to investigate this correlation with BPH in clinical cases. Fifty two cases who underwent prostatectomy were histopathologically classified into 3 types: 20 G-type, 6 F-type, and 26 M-type. W e also compared pathological types and prostatic weights with AUA symptom score in this series. Sensitivity and specifi-city of echogenic patterns were: 65.0 %, and 84.4 % G-type; 16.7 %, and 76.9 % F-type; and 76.9 %, and 53.8 % M-type, respectively. The reason for low F-type sensitivity was explained by the fact that the F-type was easily misdiagnosed as M-type. For symptom score, there was no positive relation between pathological type and prostatic weight of BPH. It was concluded that there was significant correlation between pathological types, especially G-and M-types, and the echogenic pattern in clinical cases with BPH.
