Brief Summary

Prostate cancer is the most common cancer in Australian men. Robot-assisted radical prostatectomy (RARP) - surgical removal of the prostate - is a standard treatment, but it frequently causes erectile dysfunction (ED) and urinary incontinence that can persist for years and significantly affect quality of life. This trial (ROBOPREP) will test whether a multimodal program of prehabilitation (before surgery) and rehabilitation (after surgery) improves erectile function and urinary continence in men undergoing RARP, compared to standard care alone. The program includes four components, all delivered virtually and in a self-directed manner: 1. Pharmacological - tadalafil 5 mg once daily (a low-dose, TGA-approved erectile medication) beginning 4 weeks before surgery, paused during hospital admission, and resumed for 3 months following catheter removal after surgery. 2. Exercise - pelvic floor muscle training (3 sets per day) and aerobic exercise (40 minutes, 4 times per week) to strengthen the muscles and vascular supply involved in erectile and urinary function. 3. Nutrition - dietary guidance to support surgical recovery and vascular health. 4. Psychological/wellbeing - relaxation techniques, psychoeducation about expected recovery, and self-compassion strategies to address cancer-related anxiety. A total of 64 men will be recruited across three major Sydney hospitals (Royal Prince Alfred Hospital, Concord Repatriation General Hospital, and Chris O'Brien Lifehouse) and randomly assigned 1:1 to the multimodal program plus standard care, or to standard care alone. Outcomes - including erectile function (primary), urinary continence, quality of life, and psychological wellbeing - are assessed at baseline and at 6 weeks, 3, 6, and 12 months following surgery. All participant-facing elements of the program are digital, low-cost, and designed for real-world scalability.

Eligibility Criteria

Inclusion Criteria: 1. Adults aged ≥18 years undergoing elective robot-assisted radical prostatectomy (RARP) with curative intent for confirmed prostate cancer. 2.
