Purpose/Objective:
We evaluated the relationship between erectile function and dose to the penile bulb and neurovascular bundles after real-time ultrasound-guided prostate brachytherapy. Because the neurovascular bundles are difficult to define on CT imaging, we focused on dose to the fascial plane volumes that house the neurovascular bundles and postulated that higher doses to these structures would be predictive of erectile dysfunction.
