What is a PD Catheter?
A peritoneal dialysis (PD) catheter is a soft, thin tube surgically placed in the abdomen. It allows dialysis fluid to enter and exit the peritoneal cavity, where the peritoneum (abdominal lining) acts as a natural filter to remove waste products from the blood. PD catheter placement is a minor surgical procedure that enables patients to perform dialysis at home.
The Procedure
Preparation
Empty bladder. Local or general anesthesia is given.
Incision
Small incision (2-3 cm) made in the abdomen, usually below the navel.
Catheter Placement
The catheter is threaded into the peritoneal cavity. The internal tip is placed deep in the pelvis.
Tunneling
The catheter is tunneled under the skin and exits through a separate small incision.
Securing
The catheter is secured with sutures. Dressing is applied.
Recovery
Usually done as day surgery. Catheter matures in 2 weeks before first use.
