Objective:

To investigate the different detection rates in different puncture sites under the 8-core perineal prostate biopsy guided by ultrasound

in order to help us with the choose of the best puncture scheme and the diagnosis of prostate cancer.

Methods:

The dates of 243 patients from Jan. 2015 to Jan. 2017 in Tenth Peoples Hospital

Tongji University were retrospectively analyzed. Biopsy pathologic results as the gold standard

the comparison of the differences between detecti

on rates of different puncture sites was based on two separate studies of volume and serum prostate-specific antigen (PSA) level.

Results:

According to the volume factor

there was no statistically significant differences between the puncture rates under the same volume

but there was statistically significant differences between the puncture rates under the same serum PSA level

and the result is similar according to the serum PSA level factor.

Conclusion:

The puncture rates were similar under the same volume and serum PSA level

the impact on the detection rates of volume and PSA level had statistically significant differences. In order to achieve satisfactory puncture and diagnosis results

these factors should be fully considered.
