Dialyse Péritonéale

The peritoneal dialysis


Peritoneal dialysis is a method that uses the peritoneum (abdominal membrane) as a filter to clean the blood of toxic substances.

Method and objective

A fluid called dialysate is introduced, through a catheter, into the abdominal cavity in order to rebalance the blood plasma. Its components prompt the elimination of excess water and toxic substances produced by the body.

Self-treatment at home

The benefit for the patient is that he/she is independent and remains at home. As a first step, you learn the method at the hospital.

Insertion of the catheter

The Hospital Stay

The insertion of the peritoneal dialysis catheter takes about one hour. Before returning to your room, you will spend a few hours in the recovery room.

You will be lying down for 24 hours in order to prevent the catheter from moving. A control abdominal X-ray shall be then taken. The hospital stay will last from 48h to 72h.

It takes two weeks for the catheter to heal before being able to use it. Then you may commence the treatment.

Nephrology and hypertension


Mission of the Nephrology and Hypertension Division

  • To provide diagnostic and non-surgical care to adult patients with renal disorders, taking into account the services offered by other HUG divisions
  • To provide diagnoses and treatment for patients with chronic renal failure, emphasizing the use of all applicable measures to slow or stop the progress of their disease, and coordinating the use of interdisciplinary care
  • To apply, in patients with terminal renal failure, replacement treatments including intermittent hemodialysis, peritoneal dialysis and transplantation
  • Patients may be hospitalized or outpatients. In the latter case, they are given a referral consultation by their regular physician.

Two methods

Continuous ambulatory peritoneal dialysis (manual exchange) or CAPD

CAPD is a method that requires 4 to 5 exchanges of dialysate bags per day, in accordance with doctor’s instructions. Each bag exchange takes about 30 minutes.

In a first stage, you let the liquid full of toxic substances and excess water go through the catheter out of your abdominal cavity in an empty bag. Then, you fill again the abdominal cavity with dialysate coming from a preheated bag. This liquid will remain in your abdomen until the following bag exchange.
