Is It Easier to Dialyze Women than Men?

Francisco Maduell, A. Caridad, Florencio Sigüenza, F Miralles et autres

Since the urea kinetic model is used as an objective method for monitoring dialysis, it has been possible to shorten reasonably its duration. From the usual practice, we have observed that it is easier to reduce the dialysis time in women as …

Analysis of Urea Distribution Volume in Hemodialysis

Francisco Maduell, Florencio Sigüenza, A. Caridad, F Miralles et autres

According to the urea kinetic model it is considered that the urea distribution volume (V) is that of body water, and that it is distributed in only one compartment. Since the V value is different to measure, it is normal to use …

Low Molecular Weight Heparin (CY-216) versus Unfractionated Heparin in Chronic Hemodialysis

Enric Grau, Florencio Sigüenza, Francisco Maduell, Mariano Linares et autres

In 14 patients undergoing chronic hemodialysis, we investigated the safety and efficacy of the low molecular fragment (CY-216) in comparison to unfractionated heparin (UFH) in the prevention of clotting in the extracorporeal circuit (ECC). In this study, 168 hemodialysis sessions were undertaken …

Urea Reduction Ratio Considering Urea Rebound

Francisco Maduell, Juan‐Carlos García‐Valdecasas, Hortensia Cepa García, J. Hdez-Jaras et autres

An American National Study shows that survival benefits from higher dialysis doses appear to be present up to a Kt/V level of 1.3 or a urea reduction ratio (URR) of 70%. The effect of increasing dialysis efficiency magnified urea rebound and the …

Validation of different methods to calculate Kt/V considering postdialysis rebound

Francisco Maduell, Juan‐Carlos García‐Valdecasas, Hortensia Cepa García, J. Hdez-Jaras et autres

BACKGROUND: The effect of increasing dialysis efficiency magnifies rebound urea and the error in Kt/V determinations from single pool urea kinetics. Several formulae have been developed to calculate Kt/V taking into account the rebound urea (Kt/Vr). Smye et al. proposed a method …

Treatment of nephrotic syndrome associated with idiopathic rapidly progressive glomerulonephritis and cyclosporin A

Francisco Maduell, Agustín Sánchez-Alcaraz, Florencio Sigüenza, A. Caridad et autres

Recent reports suggest that cyclosporin A is beneficial in inducing remission of idiopathic nephrotic syndrome. Nephrotic syndrome is seen in 10-30% of patients with rapidly progressive glomerulonephritis. We report a case of a 69-year-old man with nephrotic syndrome, associated with idiopathic rapidly …
