... on maintenance haemodialysis and eight healthy control subjects, matched for sex and age. Five patients had type I primary hyperoxaluria and histologically proven oxalosis, whereas 23 had oxalosis-unrelated renal diseases. Dialysis efficiency was quantified as the K d T d /V of urea. Samples were obtained from...

... clearance (RC Ox ), non-renal oxalate clearance (NRC Ox ) and the tissue oxalate accretion rate (TOA)= [(NRC Ox ) × (P Ox )] in three patients with severe renal failure due to primary hyperoxaluria who were being treated by peritoneal dialysis or haemodialysis, or by renal transplantation. The clearance...

... with primary hyperoxaluria. The renal clearance and distribution volumes of [ 99m Tc]DTPA (diethylenetriaminepenta-acetate) were measured simultaneously to provide estimates of glomerular filtration rate (GFR) and extracellular fluid volume (ECF). The same measurements were made on each of five normal...
