title: [Comparison of ultrasound-guided transrectal and transperineal prostate biopsies in clinical application].
abstract: OBJECTIVE
  To compare the positive rates and complications of ultrasound-guided transrectal and transperineal prostate biopsies.
  
  
  METHODS
  We retrospectively analyzed 156 cases of ultrasound-guided transrectal (n = 97) and transperineal (n = 59) prostate biopsy, and compared the positive rate and post-biopsy complications between the two approaches.
  
  
  RESULTS
  The positive rates in the transrectal and transperineal groups were 48.4% and 44.1%, respectively, with no significant difference between the two approaches according to different PSA levels (P >0.05). No statistically significant differences were observed between the transrectal and transperineal groups in the post-biopsy incidence rates of such complications as hematuria (54.6% vs 42.4%, P >0.05), lower urinary tract symptoms (17.5% vs 22.0%, P >0.05), dysuria (9.3% vs 6.8%, P >0.05), and acute urinary retention (7.2% vs 6.8%, P >0.05). However, the incidence rates of post-biopsy infection and rectal bleeding were remarkably higher (15.5% vs 3.4%, P<0.05 and 50.5% vs 3.4%, P >0.01) while that of perineal swelling markedly lower in the former than in the latter (3.1% vs 13.6%, P <0.05).
  
  
  CONCLUSIONS
  Transrectal and transperineal biopsies are both effective for the diagnosis of prostate cancer. Since their complications vary, the choice between the two methods depends on the specific condition of the patient.
