Questions About PD
It should be more than enough to return to PD by 4 weeks. I many cases, we are able to keep patients on PD after surgery after holding for a few days. If the patient has residual renal function, you maybe able to wait even longer to hold PD. Then you may start low volume dialysis (1 L) and withhold a day dwell if you are starting soon after surgery, then can resume full volumes generally after ~4 weeks.
