Twelve diabetics with terminal renal failure were maintained on chronic peritoneal dialysis (PD) for 2-28 months (average 10 months). 7/12 survived more than 1 year. Blood glucose levels were well controlled by the use of supplemental, intradialysis, intraperitoneal insulin. The incidence of dialysis-related complications, including peritonitis was not significantly higher than in controls. Neurophysiological studies revealed a high incidence of neuropathy initially with progression in most patients. Radiological studies revealed initial vascular calcifications in 7 out of 12 patients with progression in 4. Retinopathy did not progress significantly. PD is a suitable alternative to hemodialysis in the management of end-stage diabetic nephropathy.
