This randomised comparative study assessed pain and bleeding after digitally guided transrectal prostate biopsy using a semiautomatic needle or a fully automatic biopty gun in 64 men with lower urinary tract symptoms due to prostate disease. Each group included 32 patients, and 12 systematic cores were taken. Haematuria or urethral bleeding occurred in 37.5% (12) with the semiautomatic needle and 31.25% (10) with the biopty gun; significant rectal bleeding occurred in 31.25% (10) and 28.13% (9), respectively. Pain was greater with the semiautomatic device, but differences in pain and bleeding were not statistically significant.
Key findings
- Haematuria or urethral bleeding occurred in 37.5% (12) with the semiautomatic needle versus 31.25% (10) with the biopty gun.
- Significant rectal bleeding occurred in 31.25% (10) and 28.13% (9), respectively; the difference was not statistically significant.
- More pain was reported with the semiautomatic needle, but the difference was not statistically significant.
Why it matters
The comparison addresses whether biopsy-device choice affects common traumatic complications of transrectal prostate biopsy. In this trial, observed differences in pain and bleeding did not reach statistical significance, so the results do not establish a clear advantage for either device. The findings help frame device selection while underscoring that both approaches were associated with post-biopsy bleeding and pain.
What to keep in mind
The study included 64 patients, limiting the precision with which differences in complication rates could be assessed.
