My surgeon gave me these guidelines to start about 3 months after RC (after 3 month follow/scan):
wedges only for 2 weeks
high irons next 2 weeks
mid irons next 2 weeks
low irons/hybrids next 2 weeks
driver/fairway woods next 2 weeks
i went to driving range 2-3 times/week - once I started playing I started with 9 holes for couple of rounds and added few more holes every couple of rounds.
Doc emphasized being very mindful of any sharp pains or discomfort more than general soreness - obviously stop immediately in that case. I did use a stealth belt first few rounds til I got comfortable with how I would handle it. That would b good for racquet ball as they have a hard insert to protect the stoma. I was almost 70 when I had surgery after about 3 1/2 years of treatments for 2 cancers. Just to give u a frame of reference. My surgery was in April 2021 and I’m playing regularly and also do yoga, walking and the gym.
good luck n keep it in the short stuff!
