ABSTRACT

INTRODUCTION

evaluation of HD adequacy in patients with ESRD who were being maintained on

regular HD in a trial to identify the prevalence and causes of inadequate HD among

the patients and the impact of HD adequacy on other parameters.

DESIGN AND SETTING:PROSPECTIVE STUDY, AT SOHAG UNIVERSITY HOSPITAL IN EGYPT.

METHODS

All patients in this study were subjected to laboratory investigations including blood

urea nitrogen (BUN) (before dialysis and after dialysis), serum albumin, and

hemoglobin (Hb) level.

• URR = (1 - [postdialysis BUN ÷ predialysis BUN])

Kt/V was calculated using the second-generation Daugirdas formula

• Single-pool Kt/V = −In (R −0.008 × t) + (4 −3.5 × R)×UF/W,

R is the ratio of postdialysis to predialysis BUN; t is the length of a dialysis session

in hours; UF is the ultrafiltration volume in liters; and W is the patient’s postdialysis

weight in kilograms.

RESULTS

The results shown that 69,64% of patients had adequate HD (KT\V >1,2),and only

30,36% of patients had indequate HD (KT\V>1,2).

CONCLUSION

A significant percentage(69,64%) of patients in the HD unit of Sohag University

hospital had adequate HD. HD adequacy was influenced by several factors such as

duration and frequency of the dialysis session.
