Peritoneal dialysis

Peritoneal dialysis is a procedure to remove waste products from the blood, such as creatinine and urea, which are insufficiently removed by the kidneys in patients with renal failure. The dialysis fluid is introduced into and removed from the peritoneal cavity, and the peritoneum is used as the dialysis membrane.

    Peritoneal dialysis (PD) is the dialysis modality of choice for many regions. The application of innovative technology has led to the development of new PD devices that reduce the environmental and economic costs of the therapy, as well as miniaturized devices that provide greater freedom for patients.

    Patients on haemodialysis or peritoneal dialysis are likely to be at increased risk of novel coronavirus disease (COVID-19). Preventive strategies must be implemented to minimize the risk of disease transmission in dialysis facilities, including education of staff and patients, screening for COVID-19 and separation of infected or symptomatic and non-infected patients.

    Peritoneal dialysis has many advantages over haemodialysis in the treatment of acute kidney injury (AKI) in low-resource settings. One limitation, however, is the availability of commercial dialysis fluid. Following the International Society of Peritoneal Dialysis AKI guidelines, a frontline hospital in Cameroon now shows that locally prepared fluids are safe and effective.

    A new study suggests that peritoneal dialysis achieves a favourable mortality outcome compared with haemodialysis for the first 2 years of treatment. However, registry-based comparisons of mortality outcomes in patients with end-stage renal disease on either renal replacement modality are often fraught with complications.
