title: Transperineal prostate needle biopsy guided by transurethral ultrasound in patients without a rectum.
abstract: OBJECTIVE
  Patients with elevated prostate-specific antigen (PSA) and no access to the rectum present a diagnostic challenge to the urologist. This study was undertaken to determine the efficacy of transperineal prostate biopsy using transurethral ultrasound guidance for the detection of prostate cancer.
  
  
  METHODS
  Five men status post either total colectomy or abdominoperineal resection (age range: 58 to 73 years, mean age 65.8 years) were referred to us for the evaluation of an elevated PSA (range: 5.6 to 21.4 ng/dL, mean 16.1 ng/dL). Seven procedures were performed utilizing transurethral ultrasound to guide transperineal prostate biopsies in these men.
  
  
  RESULTS
  Biopsy results revealed benign prostatic hyperplasia in 4 procedures and prostate cancer in 3 procedures.
  
  
  CONCLUSIONS
  Transurethral ultrasound enables the practitioner to perform accurate sonographic assessment and precise biopsy of the prostate in such patients.
