Pathology and Quality of Life Outcomes Following Office-based Transperineal Prostate Biopsy.

Objective: To report the incidence of prostate cancer diagnosis and quality of life outcomes following transperineal prostate biopsy.

Methods: Forty-six consecutive patients underwent office-based transperineal prostate biopsy for an elevated prostate-specific antigen and a normal digital rectal examination without prior prostate biopsy. Prior to biopsy, a repeat prostate-specific antigen was obtained to ensure persistent elevation. Silodosin (8 mg daily) was initiated the day prior to biopsy and continued for 1 week. A total of 18-20 biopsy cores were obtained per patient. All patients responded to a visual analog scale ranging from 0 to 10 immediately following the completion of both the local anesthesia and the biopsy procedure. In addition, an International Prostate Symptom Score (IPSS), Rectal Function Assessment Score, International Index of Erectile Function, Center for Epidemiologic Studies Depression Scale, and postvoid residual were obtained at baseline and 30 days following biopsy, except IPSS which was also obtained at day 7.

Results: The mean patient age was 63.3 years with a mean prostate volume of 41.8 cm(3). The mean visual analog scale was 4.2 for the local anesthesia and 3.0 for the biopsy. Thirty-one patients (67.4%) were diagnosed with prostate cancer, with 18 having a Gleason score ≥ 7. Compared to baseline, no adverse changes in IPSS, Rectal Function Assessment Score, International Index of Erectile Function, Center for Epidemiologic Studies Depression Scale, or postvoid residual were detected at day 30. No patient required catheterization, developed sepsis, or required hospitalization.

Conclusion: Office-based transperineal prostate biopsy was well tolerated with reasonable treatment-related discomfort, a high rate of prostate cancer diagnosis, and the absence of significant morbidity including sepsis.
