Haemodialysis (HD) is the most used renal replacement therapy, and has a high complication rate under acute conditions. In this study we aimed to evaluate the etiologic, demographic, and biochemical parameters and the prognosis of patients who needed first dialysis in our center.
The study was designed as a retrospective, cross-sectional study. We evaluated 170 patients (68 female, mean age 58,7±18 years) who were dialysed for the first time during 2008. Patients were divided into two groups according to diagnosed as acute (Group1: ARF) or chronic (Group 2:CRF) renal failure.
Fifty-six of 170 patients (18 female, mean age 58,4±16,9 years) had acute renal failure(ARF) and 114 patients (50 female, mean age 58,8±18,6 years) had chronic renal failure(CRF). There was statistically significant difference in serum potassium, parathormone, and C reactive protein (CRP) levels between two groups. Femoral catheterization was the most common vascular access in both groups. The major dialysis indications were uremia, hyperkalemia, and hypervolemia. In Group 2, 48.8% of patients were not aware of their illness until the dialysis started. In evaluation of current status, 50% of acute renal failure patients were died, 35% were alive with normal renal function, 12,5% were undergoing dialysis treatment, and 2,5% treated by transplantation. Among chronic patients mortality rate was 16,9%, 72% of patients were undergoing HD, 6,7% on peritoneal dialysis (PD), and 4,5% of patients had transplantation. Acute tubular necrosis and postrenal etiology were the most common etiology in Group 1. Diabetes mellitus and hypertension were the most common etiology in group 2.
In conclusion, although most of the patients had CRF, about half were not aware of their illness, while only small portion of patients who were aware had a fistula. ARF had still higher mortality rate than chronic patients.
