Evaluation of erectile potency and radiation dose to the penile bulb using image guided radiotherapy in the CHHiP trial

Background and purposeThe penile bulb (PB) dose may be critical in development of post prostate radiotherapy erectile dysfunction (ED). This study aimed to generate PB dose constraints based on dose-volume histograms (DVHs) in patients treated with prostate radiotherapy, and to identify clinical and dosimetric parameters that predict the risk of ED post prostate radiotherapy.Materials and methodsPenile bulb DVHs were generated for 276 patients...
