It describes the insertion procedure (anesthesia, examination, Foley catheter, ultrasound-guided applicator placement, packing), CT or MRI planning with the GEC-ESTRO MRI sequences, the GTV, high-risk and intermediate-risk CTVs, the traditional ICRU 38 points, HDR schedules of 6–8 Gy in 3–5 fractions to the HR-CTV, and total EQD2 aims for the target and for bladder, rectum, sigmoid and bowel D2cc, most credited to EMBRACE II and GEC-ESTRO. Its review is due 31 December 2026.
