This is Episode 31: Penile and Urethral Planning Workshop. These are rare, high-stakes plans. The anatomy is mobile, the setup can be awkward, the evidence base is limited, and sloppy field design can have major consequences. This workstation episode covers simulation, bolus, immobilization, penile brachytherapy, inguinal and pelvic nodal contouring using the InPACT framework, and key principles of urethral cancer planning.
