Summary
The 2012 Japanese registry survey shows a slight decrease in peritoneal dialysis (PD) patients. Combined PD and hemodialysis use increases with PD duration, while automated PD machine use declines over time.
Area of Science:
- Nephrology
- Public Health
- Medical Statistics
Background:
- The Japanese Society for Dialysis Therapy conducts an annual nationwide survey, including PD registry data since 2009.
- This report analyzes the 2012 survey data to present the current status of peritoneal dialysis (PD) patients in Japan.
Purpose of the Study:
- To describe the current status of PD patients in Japan based on the 2012 survey.
- To analyze trends in combined PD and other dialysis methods, dialysate exchange techniques, APD usage, and infection rates.
Main Methods:
- Descriptive analysis of data from the 2012 PD registry survey.
- Inclusion of patients residing in Japan who participated in the 2012 survey.
- Analysis of combined PD with hemodialysis (HD) or hemodiafiltration (HDF), dialysate exchange methods, automated PD (APD) machine use, and infection rates.
Main Results:
- The number of PD patients decreased to 9514 in 2012, representing 3.1% of all dialysis patients.
- Combined PD and other dialysis methods increased with PD vintage, reaching 47.5% for patients with ≥8 years of PD.
- Manual dialysate exchange was used by 29.8% of patients; APD use was highest in patients with <1 year of PD.
Conclusions:
- The PD patient population in Japan saw a slight decrease in 2012.
- Combined dialysis modalities are increasingly used by patients with longer PD vintage.
- Rates of peritonitis and catheter exit-site infections were reported as 0.22 and 0.36 per patient-year, respectively.

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
