Abstract
To assess the technical aspects determining the perceived pain during prostate biopsy via transperineal access.
Materials and Methods
We conducted prostate biopsy with transperineal access in local anesthesia. Between January 2007 and January 2008, data on prostatic biopsies were prospectively surveyed. The patient was requested to assess perceived pain by means of a Visual Analogue Scale ranging from 0 (no pain) to 10 (unbearable pain). Complications were recorded by telephone interviews 30 days after the biopsy. The histological diagnosis was recorded.
Results
445 prostate biopsies were conducted. The average perceived pain score amounted to 2.60. At univariate analysis, a lower score was recorded in cases where the anesthetic agent was diluted with physiological saline, those in which a single cutaneous access was chosen along the middle line, those in the first bioptic series as compared to the following series and those in which no sampling involved the transition region. However, the multivariate analysis showed that only the single cutaneous access was statistically significant. In those cases, also the rates of delayed perineal pain were significantly lower. The cancer diagnosis rate showed no correlations with the type of cutaneous access.
Conclusions
A single median cutaneous access reduces the pain associated to transperineal prostatic biopsy.
