The outer prostate capsule was refined by surface subdivision. The urethra was cropped near the gland. Model metadata records the geometry layout and reference structures.

Website-specific illustrative adaptations: display colours and studio lighting; camera interaction; sections derived from triangle-plane intersections; one illustrative gold marker. These do not represent a patient, a measured tumour, an AI result or a surgical navigation model. No source viewer code is included. No endorsement by the creators or institutions is implied.
