Novel Prostate Biopsy Technique Using Imaging Fusion in a Patient With Absent Rectum

A 70-year-old male with prior total colectomy for ulcerative colitis was referred for elevated prostate specific antigen (PSA) (8.01) with PIRADS 4 lesion on magnetic resonance imaging (MRI). Described is a novel technique using pre-operative multi-parametric prostate MRI and intraoperative computed tomography (CT) 3D/3D fusion for systematic and targeted prostate biopsy in a patient lacking a rectum.
