Author(s): Magdy Mohammad El-Sharkawy, Aber Halim Baky*, Mohammed Mustafa and Rania Roshdy Ahmed Sadek
Recirculation is an important issue in hemodialysis (HD) patients as increased percent recirculation causes decreased dialysis delivery of the patients. The purpose of the study was to determine the prevalence and possible causes of recirculation in those patients. The study was a cross sectional one carried in the department of Nephrology, Ain Shams University Hospitals. A total of 100 end stage renal disease patients with arterio-venous fistula who were on HD for more than 3 months were purposively selected. The degree of recirculation was measured with urea based two needle technique method. For each patient distances between arterial and venous and distances of needles from fistula and its directions were recorded. Echocardiography and A-V fistula Colour Doppler Ultrasound were also performed for patients with high degree recirculation percent (more than 10%). The prevalence of A-.. View more»
