The case of the missing spacer!

The SpaceOAR Vue hydrogel system was developed to reduce the toxicity to the rectum following radiation therapy for prostate cancer. Initial trial data reported the product as overall effective and safe. However, a few additional observed complications have likely been brought on by its increased utilization. The case presented herein describes rectal erosion, with abscess and rectal fistula formation, associated with the use of the SpaceOAR Vue hydrogel system. The SpaceOAR Vue hydrogel system was subsequently found to be absent between radiotherapy treatments and was thought to have been passed rectally through the fistula. The benefits and complications of the SpaceOAR Vue hydrogel system are discussed, as well as key factors to consider as the recommendation of routine use increases. [ABSTRACT FROM AUTHOR]
