BACKGROUND: Although transperineal (TP) prostate biopsy is growing in popularity, its safety has not been evaluated based on extensive studies.
We prospectively assessed the adverse events associated with transrectal ultrasound (TRUS)-guided TP 16-core prostate biopsy at a single institution.
PATIENTS AND METHODS: We enrolled 2,086 males who underwent first-time TRUS-guided TP prostate biopsy under lumbar spinal anesthesia at Chiba Cancer Center between 2009 and 2013. Eight adverse events were assessed prospectively using a purpose-designed questionnaire. The prevalence and duration of all adverse events were evaluated. We performed subgroup analyses for hematuria and urinary retention in relation to clinical factors.
RESULTS: Questionnaires were collected from 1,663 cases (79.7 %). The cancer detection rate was 53.5 % in all patients. The prevalence and duration of complications were as follows: hematuria, 73.4 % and 4.51 ± 2.88 days; perineal bleeding, 7.1 % and 2.20 ± 2.24 days; hematospermia 14.4 %; dysuria, 15.7 % and 3.12 ± 2.71 days; urinary tract pain, 49.5 % and 2.43 ± 2.08 days; perineal pain, 35.5 % and 3.53 ± 2.59 days; fever ≥37 °C, 1.7 % and 1.79 ± 1.72 days; and headache, 22.1 % and 3.40 ± 2.10 days. Seventeen patients (1.1 %) required indwelling urethral catheterization for grade 2 urinary retention. Pre-biopsy International Prostate Symptom Score (p = 0.014) was an independent related factor for hematuria. Prostate volume (p = 0.001) was an independent related factor for grade 2 urinary retention.
CONCLUSIONS: TRUS-guided TP prostate biopsy under lumbar spinal anesthesia can be performed safely with only minor adverse events.
