Comparison of Traumatic Complications following Prostate Biopsy in Men with Lower Urinary Tract Symptoms Due to Prostate Disease Using Biopty Gun versus Semiautomatic Needle.

Abstract

Prostate biopsy has evolved to improve yield and reduce complications. The development of biopty guns added to this trend. It is an improvement on the semiautomatic needle. This study aimed to compare semi-automatic and fully-automatic biopsy devices used for digitally guided transrectal prostate biopsy for the rate and extent of post-biopsy pain and bleeding complications. Sixty-four patients were randomised into two groups, each with 32 patients. Group 1 patients were biopsied with 16G Medplus ® semi-automatic biopsy needles, whereas Bard-Magnum ® biopty gun with 16G needles was used for Group 2. Twelve systematic cores were taken from both groups. Post-biopsy pain was assessed using the Numeric Rating Scale and Wong-Baker Faces Pain Rating Scale. The rate and extent of post-biopsy haematuria/urethral bleeding and rectal bleeding were evaluated. Data were collected using a structured pro forma and analysed using IBM-SPSS. Sixty-four men participated in the study. Haematuria/urethral bleeding occurred in 37.5% (12) and 31.25% (10) patients in Groups 1 and 2, respectively. Bladder irrigation was done for 8.3% (1) and 20% (2) of those who bled from Groups 1 and 2, respectively. Significant rectal bleeding occurred in 31.25% (10) and 28.13% (9) patients from Groups 1 and 2, respectively. More pain was noted in Group 1. These differences in bleeding complications and pain were not statistically significant. The two devices did not exhibit significant differences in terms of pain or bleeding complications when used for prostate biopsy.
