Case Study

Prostate Drainage

All Case Studies

Even with an extremely long trajectory to target, the robot enabled the attending physician to reach the target with 1mm tip-to-target accuracy without requiring any patient repositioning, despite the target update toward the end of insertion.


The patient presented with a large prostate abscess, which can often be a tricky location due to the anatomy surrounding the prostate. This procedure had a long trajectory to target of 128mm. 

There was a last-minute target update to ensure the tip of needle was in an ideal location for final insertion to allow for adequate drainage. 

Overall, the insertion was completed in a total of 11 minutes with 1mm tip-to-target accuracy.
