Total dialysate calcium effects on calcium balance during dialysis.

Introduction: Total dialysate calcium concentration has an important influence on calcium metabolism in bicarbonate high-flux dialysis. The aim of the study is to investigate the influence of different dialysate calcium concentrations on serum concentration of ionised calcium and on the balance of total dialysate calcium.

Materials And Methods: A total of 20 stable aneuric patients on chronic bicarbonate high-flux haemodialysis with a frequency of 4 hours, 3 times per week with two different concentrations of total dialysate calcium (tdCa) were included in the study.

Renal histopathology and clinical course in patients with Wegener's granulomatosis--single centre experience from the Republic of Macedonia.

The aim of this study was to evaluate the clinical course of patients with Wegener's granulomatosis (WG) with renal involvement, to examine histopatological form seen in renal biopsies and present follow-up of the patients. A retrospective analysis was carried out of 18 patients presenting with WG and active renal disease at the University Nephrology Department, Ss. Cyril and Methodius University, Skopje, R.

The Oxford classification of IgA nephropathy: single centre experience.

The Oxford classification for the pathological classification of a glomerular disease in IgA nephropathy was established and published in 2009. Four of the pathological variables: 1) mesangial hypercellularity score, 2) segmental glomerulosclerosis, 3) endocapillary hypercellularity and 4) tubular atrophy/interstital fibrosis were presented as having value in predicting renal outcome in this glomerular disease. These features were recommended to be taken into account for predicting the outcome.

Dialysis and aphaeresis in the Republic of Macedonia "a success story".

The first haemodialysis (HD) in the Republic of Macedonia (RM) was performed in 1959 in a patient with acute renal failure (ARF) using Kolff-Brigham rotating drum artificial kidney at the Blood Transfusion Institute in Skopje. In 1965 the Renal Unit at the Dept. of Medicine, Medical Faculty, Skopje obtained a modern, new artificial "Websinger" kidney with sigma motor pump and possibilities for use of disposable Kolff "twin coil" dialyser.

Doppler ultrasonography: a tool for nephrologists--single centre experience.

Colour Doppler duplex ultrasonography (CDUS) has allowed noninvasive assessment of alterations of vascular perfusion showing general perfusion in colour. Since 1996, ultrasound examination by a duplex Doppler apparatus has been performed with an HDI 3000, ATL machine. We have retrospectively evaluated all patients (pts) with colour Doppler duplex examination for the last three years.
