CABRERA, Walter Eduardo  y  SANTA CRUZ, Francisco Vicente. Incremental hemodialysis. A therapeutic proposal?. An. Fac. Cienc. Méd. (Asunción) [online]. 2020, vol.53, n.3, pp.147-152. ISSN 1816-8949.

Several methods are useful to measure renal function (RF). In clinical practice, the creatinina cleareance (CrCl), is widely used, which approximately reflects the glomerular filtration rate (GFR). The 24 hs urine volume collection is required to measure CrCl, however, thanks different formulas we can have a precise CrCl value. The CKD-EPI (chronic kidney disease epidemiology collaboration), is the equation frequently used. According to glomerular filtration rate (GFR), the renal function has been classified in 5 stages. At advances stages (stage 5), (CrCl: 15 ml/min), the patient is faced to receive renal replacement therapy (RRT). Hemodialysis (HD) method is often used. It is carry out 3 times per week (4 hours each).

A 59 years old male, due to the distance between the Capital City and his home, decided to receive HD only two times per week (signed consent). At the beginning of the treatment the patient presents all the clinical and biochemical data corresponding to Chronic Renal Failure stage 5. His diuretic volume (DV), ≥ 1 lt/day. In the case of RF deterioration reflected clinical and/or biochemically, the HD session would be 3 times a week.

At year, presents adequate residual renal function (RRF) and clinics, biochemical parameters as well. If the RRF (measured by urea clareance (Kru) and the DV) decline, 3 sessions per week will be necessary. The RRF maintenance is related to mortality, therefore, its preservation thanks incremental HD, improve the patient survival.
