History and Objectives: Patients at end-stage renal disease (ESRD) need dialysis for living and because of dialysis insufficiency a high mortality has been reported. Nowadays, more than 200000 patients with renal disease existed in USA and more than 1 million patients live through dialysis. Therefore, this study was performed for evaluation of dialysis sufficiency in hemodialysis patients in Kashan in 1998.

Materials and Methods: The descriptive strategy of this study was carried out on patients with ESRD and under hemodialysis. The parameters age, height, gender, weight, dialysis duration, Pres KV, del KT, cPCR, … were collected in a questionnaire and were presented in frequency tables.

Results: This study was performed on 37 patients and those with other causes including poisoning were excluded. Out of 37 patients, 15 cases (40.5%) were female and 22 cases (59.9%) were male. For Pres KT/V and, an average of 10.4 was obtained (0.92 for males and 1.23 for females) and for del KT/V, it was 0.45 and 0.48 in males and females respectively. In addition, an average of 33.8 in males and 33.34 in females was obtained for Tacurea. For URR, an average of 0.3 was observed (0.31 for males and 0.29 for females). Finally, 7 patients (18.9%) had a sufficient dialysis, that is a KT/V higher than 1.2.

Conclusion: Since hemodialysis is insufficient in nearly 80% of patients with renal diseases, it is needed to carry out more studies in other cities of the country.
