Understanding Peritoneal Dialysis
Peritoneal dialysis is a treatment used when the kidneys can no longer remove waste and excess fluid from the body effectively.
Unlike hemodialysis treatment, which filters blood through a machine, peritoneal dialysis uses the body’s natural abdominal lining as a filter. The lining of the abdomen, called the peritoneum, contains many small blood vessels that allow waste and extra fluid to pass into a cleansing solution.
During treatment, a sterile fluid called dialysate is placed into the abdomen through a small catheter. The fluid absorbs waste products and excess fluid from the blood. After a period of time, the fluid is drained and replaced with fresh solution.
This process helps maintain safe levels of minerals and fluids in the body when the kidneys can no longer perform these functions on their own.
Peritoneal dialysis is one of several home dialysis therapies that allow some patients to receive treatment outside of a dialysis center.
Types of Peritoneal Dialysis
There are two primary forms of peritoneal dialysis. Both remove waste from the body but differ in how the exchanges are performed.
Continuous Ambulatory Peritoneal Dialysis (CAPD)
CAPD is performed manually throughout the day without the use of a machine.
During this treatment, the abdomen is filled with dialysis fluid that remains in place for several hours. After the dwell time, the fluid is drained and replaced with new fluid. This process is typically repeated several times each day.
Many patients appreciate CAPD because it can be performed in a variety of settings and does not require a machine.
Automated Peritoneal Dialysis (APD)
Automated peritoneal dialysis uses a machine called a cycler to perform exchanges automatically.
This treatment usually takes place overnight while the patient sleeps. The cycler controls the flow and timing of the dialysis fluid throughout the treatment cycle.
Many patients choose APD because it allows dialysis to occur at night, leaving the daytime hours free for normal activities.
Benefits of Peritoneal Dialysis
Peritoneal dialysis offers several advantages for patients with advanced kidney disease.
Possible benefits include:
- Treatment performed in the comfort of home
- Greater flexibility with daily schedules
- Fewer visits to a dialysis center
- Gradual removal of waste and fluid
- The ability to maintain more independence
Peritoneal dialysis is not the best option for every patient. Your nephrologist will help determine whether this therapy fits your medical needs and lifestyle.
Patients in the Tulsa area often choose this treatment because it allows them to receive dialysis while continuing many normal daily routines.
Peritoneal Dialysis vs Hemodialysis
Both treatments remove waste from the body when kidneys stop working effectively. The main difference is how and where the treatment occurs.
| Treatment | Where Treatment Happens | Typical Schedule |
|---|---|---|
| Peritoneal Dialysis | At Home | Daily exchanges or overnight |
| Hemodialysis | Dialysis center or home | Usually three times per week |
Your nephrologist will review both options and help you decide whether hemodialysis treatment or peritoneal dialysis is the best approach for your care.
Is Peritoneal Dialysis Right for You?
Choosing a dialysis method is a personal medical decision that depends on several factors.
Peritoneal dialysis may be recommended for patients who:
- Want greater flexibility with dialysis treatment
- Prefer dialysis at home rather than a center
- Have stable medical conditions that allow home therapy
- Are comfortable learning the treatment process

Frequently Asked Questions About Peritoneal Dialysis
Peritoneal dialysis uses the lining of the abdomen to filter waste from the blood. Hemodialysis uses a machine that filters blood outside the body. Many patients choose peritoneal dialysis because it can be performed at home.
Yes. Peritoneal dialysis is designed for home use. After training, many patients manage treatment independently or with help from a caregiver.
Treatment schedules vary. Some patients perform manual exchanges several times during the day. Others use an automated cycler overnight while they sleep.
Peritoneal dialysis is a safe and effective treatment for many patients when performed correctly. Your care team will provide training, monitoring, and ongoing support.
Patients who want flexibility with treatment and are able to perform dialysis at home may be good candidates. Your nephrologist will determine whether this option is appropriate for your health needs.
Many patients continue working or maintaining daily routines while on peritoneal dialysis. Treatment schedules can often be adjusted to fit work and personal schedules.
Dialysis helps perform many of the functions normally handled by healthy kidneys. However, it does not fully replace all kidney functions. Your care team will continue monitoring your health and adjusting treatment as needed.
