Residual Kidney Function & Incremental Dialysis Suite

Preserve your remaining native kidney function. Calculate your 24-hour residual urea clearance (KrU), creatinine clearance (CrCl), residual GFR, and weekly renal Kt/V, and evaluate candidacy for twice-weekly incremental hemodialysis or reduced peritoneal dialysis under KDOQI 2015 and KDIGO 2024 guidelines.

Educational Consultation Tool: Preserving even minimal residual urine output (300–1000 mL/day) confers dramatic benefits: improved fluid balance, less severe dietary restrictions, lower systemic inflammation, reduced left ventricular hypertrophy, and enhanced survival. Initiating dialysis with twice-weekly sessions protects residual nephrons from ischemic stunning. This suite assists patients in preparing 24-hour urine collection results for nephrology consultation.
