Abstract
|
|
|
Tissues obtained by transurethral prostatectomies were evaluated histologically and cdorrelated with the clinical findings and the transrectal ultrasonographic pictures of 104 patients with benign prostatic hyperplasia (BPH). The patiens were
divided
dinto 3 groups accordingd toe the following histology: preddominantly glandular types (30 patients), predominantly stromal types (35 patients) and mixed types which have equeal proportions of landular and stromal hyperplasia (39 patients).
The average age was highest in the glandular group. Postoperative obstructive sypmptom scores were significantly lower in the stromal type as compared to the glandular and the mixed type. The maximal flow rates at three months following the
operations
were highest in the stromal type. In comparision of the hyistologic findings with preoperative transrectal echographic pictures, the transverse and the longitudinal diameter of the transitional zone were significantly lower in the stromal type
than
in
the glandular and the mixed type. The weight of transitional zone was significantly smaller in the stromal type than in the glandular and the mixed type. The evchogenicity showed hyperechoid and isoechoic pattern in the stromal and hypoechic and
isoechoic pattern in the glandular type. The echographic homogeneity, the frequency of prostatic calculi and cyst formation, and the margination of the transtitional zone did not show any significant difference among each group.
In conclusion, the histologic types of BPH have correlations with the clinical findings and the transrectal ultrasonographic pictures. Furthermore precise interpretation of the histologic types of HPH by transretal ultrasonotgraphy will be
helpful
in
decision making about the treatment modality and in predicdtion of the clinical progress after somed treatment for the pastients with BPH.
