The Value of Transrectal Ultrasonography in Benign Prostatic Hyperplasia / 대한비뇨기과학회지

ABSTRACT

Transrectal ultrasonography was done in 14 healthy men and 52 patients with benign prostatic hyperplasia to demonstrate the pathomorphology of the prostate and to determine the preoperative prostatic size. We found that the transrectal ultrasonographic examination allowed for an accurate estimation of the prostatic size. The following results were obtained. 1. The average values of anterioposterior, transverse and longitudinal diameter were 2.45+/-0.49 cm. 4.12+/-0.69 cm and 3.39+/-0.42 cm in control group and 3.37+/-1.06 cm. 5.07+/-0.71 cm and 4.46+/-0.84 cm in BPH. 2. The average weight of the prostate was 20.07+/-5.15 gm in control group and 47.02+/-25.81 gm in BPH. 3. In patients treated with transurethral resection of the prostate the mean estimated weight was 36.0 gm while the mean actual resection weight was 11.4 gm The difference between these 2 values was 24.6 gm. 4. In patients treated with open prostatectomy the mean estimated weight was 78.8 gm, while the mean actual resection weight was 48.7gm. The difference between these 2 values was 30.1 gm.
