Peritoneal dialysis

Also written as: PD — Peritoneal Dialysis

Renal replacement therapy using the peritoneum as a natural filter, relevant in laparoscopy for catheter placement.

Full Definition

A form of dialysis that uses the patient's peritoneal membrane as a semi-permeable filter to remove waste products and excess fluid from the blood. In laparoscopic surgery, this is relevant primarily for the placement of peritoneal dialysis catheters using minimally invasive techniques. Laparoscopic catheter insertion offers advantages including direct visualization of catheter placement, ability to perform adhesiolysis if needed, and reduced risk of bowel injury compared to traditional blind insertion techniques.

Usage

Usage note: Abbreviate as PD only after first use. CAPD refers specifically to continuous ambulatory peritoneal dialysis.
