- PURPOSE: We evaluated the efficacy and clinical usefulness of the transrectal ultrasonographically guided automated gun biopsies in the diagnosis of prostatic diseases.
MATERIAIS & METHODS: During a 8-month period, 40 patients (mean age 60years old men) transrectal sonographically guided automated gun biopsies were done because of prostatic disease (adenocarcinoma, sarcoma, metastasis and benign prostatic hyperplasia with abnormal sonographic finding). 31 cases were inpatients and 9 cases were outpatients. We performed a direct biopsyinto a hypoechoic lesion or random 4 core biopsies. We used prophylactic antibiotics for 3 days.
RESULTS : Biopsy specimens were sufficient in 40 cases (100%). Histologic examination of biopsy specimens revealed adenocarcinoma in 7 cases, nodular hyperplasia in 23 cases, chronic inflammation in 2 cases, spindle cell tumor in 1 case, small cell carcinoma in 1 case, tuberculosis in 1 case, basal cell hyperplasia in 1 case, normal in 4 cases. There was mild degree of pain in all patients during biopsy, and 3 cases (7.5%) had hematuria for 1 day, but they recovered the normal state without any treatment.
CONCLUSION: Transrectal ultrasound guided prostate biopsy using automated gun biopsy system is considered a safe, easy and useful procedure to confirm diagnosis of prostatic disease, especially to increase in number of detection rate of prostatic cancer
