Starting dialysis with fewer sessions and increasing as residual kidney function declines — preserves residual function and reduces burden.
Incremental HD starts at 1-2 sessions/week in patients with meaningful residual kidney function (measured by urea clearance), titrating up to 3×/week as function falls. Residual diuresis and urea clearance are monitored; underdialysis must be avoided. Benefits include longer preservation of residual function and lower treatment burden.
A medical procedure that filters waste products, excess fluids, and toxins from the blood using a dialysis machine when the kidneys can no longer perform this function adequately.
The kidney function a dialysis patient retains after starting treatment — worth preserving, since it improves survival and quality of life.
A dimensionless number used to quantify dialysis adequacy, where K = dialyzer clearance, t = treatment time, and V = volume of distribution of urea.
A nitrogen waste product from protein breakdown that the kidneys excrete; high blood urea (BUN) signals reduced filtration or high protein intake.
