Advantages of single-puncture transperineal saturation biopsy of prostate: Analysis of outcomes in 125 patients using our scheme - Abstract

PURPOSE: Stereotactic biopsy has improved prostate cancer detection.

Although the new approach is superior, standard procedure is still useful in a cohort of patients in whom MRI is not available. The standard saturation biopsy technique is still debatable. We describe our technique and analyze its outcomes.

MATERIALS AND METHODS: One hundred twenty-five patients underwent saturation biopsy through a single transperineal access. Mean age was 64.73 year, mean PSA was 9.49 ng/ml, mean PSA density was 0.184, and mean prostate volume was 57.95 g. All patients underwent at least one previous prostatic biopsy: 24.8 % of cases had diagnosis of atypical small acinar proliferation, 39.2 % of cases had multifocal high-grade prostatic intraepithelial neoplasia, and 36 % of cases had inflammation or benign prostatic hyperplasia.

RESULTS: The detection rate was 38.4 %. Prostate cancer occurred in 61.3 % of patients with previous ASAP (p < 0.007). Cancer detection rate decreased with increasing number of previous biopsy and with increasing prostate volume (p < 0.001) and increased with increasing PSA density (p = 0.03). No major complications were reported.

CONCLUSION: The traditional saturation biopsy may be useful when targeted biopsy cannot be used. Our technique is accurate for cancer detection. It can offer some advantages in comparison with other approaches.
