@hello1234 My husband chose to go with PD. He never had any issues until a month before transplant when he ended up with diverticulitis, and in the ER a tech pulled a sample of his peritoneal fluid, but it was a "dirty" catch. He ended up with an infection, and was put on antibiotics. In those two weeks, he was called twice for transplant, but couldn't. Two weeks after he ended antibiotics, he was called and got his new kidney! He slept well, after he figured out where to place the machine for minimal noise interruption [in the closet!]. He even went on long motorcycle trips carrying his machine, camping out in the desert using solar powered batteries to run the machine at night, cross-country business trips. His medical supplier [Baxter] went very responsive to drop-ship the solution wherever he needed them to.

You can go to this discussion post, and read from there. Lots of information on dialysis. https://connect.mayoclinic.org/discussion/dialysis/
Also, look at Mayo Clinic's information on hemodialysis https://www.mayoclinic.org/tests-procedures/hemodialysis/about/pac-20384824 and on peritoneal dialysis https://www.mayoclinic.org/tests-procedures/peritoneal-dialysis/about/pac-20384725
Lastly rsnhope.org offers a bunch of information about kidney disease and different procedures.

Let me know if I can be of further assistance for your cousin?
