Overall, prostate biopsy is a safe procedure but it is important to be aware of the risks.
Despite precautions, up to 5% of men will develop an infection after the biopsy
, requiring more antibiotics and extended hospital stay.
Upto 15% of men notice some blood in their urine, upto 20% notice some blood in stools and about 38% notice blood in their semen. This bleeding is usually minor but can go on for up to a week. Bleeding is slightly more likely if you are/were taking warfarin/ clopidogrel tablets.
Some of them who already had poor urinary flow and high residual urine volume before the biopsy, may not be able to pass urine and go for urinary retention, in which case , may require placement of temporary catheter in the urinary passage to drain urine.
