@blbird33 My husband received a kidney October 1, 2016, at Scripps Green Insitute in the San Diego [CA] area. He had been on PD dialysis for 5.5 years before receiving that gift of a second chance for normal life. His team did not remove the PD cathter until about 3 weeks after the transplant. At that time, they did a "trifecta", doing a kidney biopsy on the [deceased] donor kidney, removing the stent placed between new kidney and bladder at time of transplant, and the cathter. Their reasoning was if the new kidney did not wake up, he would need to stay on dialysis until it did, and they wanted a treatment option. He didn't have any problems with the healing of the site,

Some people seem to develop more scar tissue of keloid type tissue, than others do. In my case, my PD catheter has its own little emphasis on one side based on the way it exits my skin. Have you ever had scar tissue build up other places on your body, like piercings?

What might work is massaging the area gently everyday, perhaps with Vitamin E based product. It's worth a try!
