A study of transrectal ultrasonographic graduation for the diagnosis of benign prostatic hyperplasia / 中华超声影像学杂志

ABSTRACT

Objective To study the methods of graduation of benign prostatic hyperplasia.Methods Transrectal digital palpation,transabdominal and transrectal ultrasonography,uroflowmetry and measuring residual urine volume were carried out for 320 cases of benign prostatic hyperplasia.Results①The measuring prostatic volume by means of transrectal digital palpation and ultrasound was similar.There was no significant difference between the groups(P=0.991).②The obstructive degree of the urethra was not consistent with the prostatic volume(P<0.01),it was closely related to the degree and site of hypertrophy node.③Measurement of size of prostatic internal gland,proportion between internal and external gland,site of internal ostium of urethra and sonography during urination were carried out by transrectal ultrasonography.The results were similar with obstruction pressure of the urethra and clinical manifestation(P=0.848, 0.966,0.592).Conclusions The transrectal ultrasonography graduation is not only a reliable method for diagnosis of benign prostatic hyperplasia,but also can guide the treatment of benign prostatic hyperplasia.
