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 types which have equal proportions of glandular and stromal hyperplasia (39 patients). The average age was highest in the glandular group. Postoperative obstructive 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 comparison 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 the 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 isoechoic 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 about the treatment modality and in prediction of the clinical progress after some treatment for the patients with BPH.
