Primarily: findings of the efficacy of periodical hemodialysis according to the formula KT/V

The value of formula Kt/v has been calculated by Daurgidas method in order to assess the effectiveness of chronic hemodialysis on 22 patients from Dialysis Center of Friendship hospital. These patients had mean Kt/v=1.33, with range from 0.92 to 1.67. Patients with Kt/v value (1.33 seem to have better recovery ability. Good effect of dialysis, with Kt/v(1.33 could be achieved by two-session-per-week hemodialysis, using high efficiency dialyzes and with session lasting at least 5 hours
