Clinical Evaluation of Benign Prostatic Hyperplasia According to Histologic types
|
|
|
|

Abstract
|
|
|
Tissues obtained by transurethral prostatectomies were evaluated histologically and correlated with the clinical findings and the transrectal ultrasonographic pictures of 104 patients with benign prostatic hyperplasia(BPH). The patients were
divided
into 3 groups according to the following histology: predominantly glandular types(30 patients(, predominantly stromal types(35 patients) and mixed which have equal proportions of glandular and stromal hyperplasia(39 patients).
The average age was highest in the glandular group. Postoperative obstruction symptom 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 histologic 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 mixed type. The weight of transitional zone was significantly smaller in the stromal type than in the glandular and the mixed type.
The echogenicity showed hyperechoic and lsoechoic pattern in the stromal and the mixed type and hypoechoic and isoechoic pattern in the glandular type. The echographic homogeneity, the frequency of prostatic calculi and cyst formation, and the
margination of the transitional 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 BPH by transrectal ultrasonography will be
helpful
in
decision making abut the treatment modality and in prediction of the clinical progress after some treatment for the patients with BPH.
