Dialysis adequacy is described as reducing mortality ayid morbidity rates besides improving the uremic symptoms of patients. In this study, it was aimed to assess the relationship between dialysis adequacy determined by urea kinetic model (UKM) and co-morbid factors. Daily Kt/V (Kti/V) value was determined in 52 hemodialysis (HD) patients. A morbidity score (MORS) was created by scoring seventeen clinical, biochemical and radiological parameters as one or zero. Daily Kt/V(Kti/V) of HD patients was found 0.41. The Kti/V value of HD patients was found to be 19.6 % lower than the value proposed by NKF-DOQI. There was a positive correlation between Kti/ V and normalized protein catabolic rate (nPCR) (r=0.814, p<0.01) and a negative correlation between Kti/V and MORS (r=-0.314, p<0.05) while there was no correlation between Kti/V and the other individual parameters of MORS. We concluded that, in assessing the adequacy of dialysis, morbid factors were efficient as well as UKM and it could have been a mistake to use only Kt/V for determining dialysis adequacy.
