Peritoneal dialysis (PD) really became a choice for kidney failure management when a semipermanent access to the peritoneum was developed. Before the development of such a catheter, access was achieved by placing a temporary peritoneal catheter at the bedside, after which the patient would be dialyzed, often for 20 hours using 1dwell per hour, always in the supine position. Then the temporary catheter would be removed until the next treatment cycle. The disadvantages of this approach are obvious.
