The Analysis of Prostate Cancer Diagnosis and Complications according to
Biopsy Strategy guided by Trans-Rectal Ultra Sonography(TRUS)

Purpose : Generally the diagnosis of prostate cancer has been procedured by pro state biopsy guided by transrectalultrasonography (TRUS). An increase in the number of prostate biopsy procedures, causes increase in both cancer detectionrates and associated complications. The purpose of this study is to analyze of prostate cancer detection rate and complicationsaccording to prostate biopsy strategy.Methods : We analyzed the 365 patients who visited Jeju National University(JNU) Hospital from March 2009 to January 2012,conducted the prostate biopsy guided by TRUS. The patients with prostate cancer might show the noticeable symptomsincluding high PSA level, palpable nodule in the prostate rectal examination, or low echo lesion in TRUS. We divided the patientsinto 2 groups: Comparison of sextant biopsy (group 1) and 10 prostate biopsy (group 2).Results : There was no difference in average age and past medical history such as diabetes mellitus(DM), hypertension(HTN)or cerebro vascular accident(CVA) between two groups. However, prostate specific antigen (PSA) level was higher in group 2.We detected a variety of complications such as hematuria, acute urinary retention, urinary tract infection and rectal bleeding inboth groups. Except rectal bleeding, there were no differences in the complications. The diagnosis of prostate cancer washigher in group 2, and statistically significant (p = 0.012). There was no significant difference in Gleason score between twogroups.Conclusion : The procedure of prostate biopsy guided by TRUS is generally safe, and 10 location of prostate biopsy usingTRUS can further help in prostate cancer diagnosis.
