RESUMO
A study was conducted in radiology department CMH Rawalpindi to determine the role of transrectal ultrasonography in the evaluation of prostatic diseases. A total of 78 cases were examined with transrectal ultrasound probe and later followed for histopathological findings. Transrectal ultrasound was found correct in 51 cases of benign prostatic hyperplasia and 16 cases of prostatic carcinoma. Two cases of prostatitis with prostatic abscess were also noted. The sensitivity and positive predictive value for prostatic carcinoma in our study were 80% and 76.19% respectively. In 16 cases of prostatic carcinoma, the digital rectal examination was positive in only 08 cases and raised serum prostate specific antigen were noted in 13 cases. In view of this study, it is recommended that transrectal ultrasonography should be adopted for pre-operative assessment of benign prostatic hyperplasia, diagnosis / staging of prostatic carcinoma and in all clinically suspected cases of prostatic abscess
