title: [Incidence of chronic renal failure during 35 years at the Rijeka Clinical Hospital Center].
abstract: Chronic hemodialysis treatment in the world started in 1960. At that time, due to technical development and construction of arteriovenous shunt for repeated blood access for dialysis, it was possible to treat uremia. At the Department of Surgery, Rijeka Clinical Hospital, former Dr. Zdravko Kucić Hospital, first hemodialysis was performed in 1962, whereas regular chronic dialysis treatment started in 1966. On September 20, 1966, the first hemodialysis was done in a patient with chronic uremia. A week later, the next patient was admitted for therapy. The aim of the study was to analyze demographic and other data of all patients who started dialysis in the period between 1966 and 2001. There were 910 patients, 555 (60.9%) male and 355 (39.1%) female. In the first year, only two patients were treated with hemodialysis. Until 1970, the number of new patients was 4 or 5. From 1971 till 1984 between 10 and 19 new patients started dialysis every year, and from 1985 till 1990 their number ranged from 23 to 34 per year. Further increase in the number of treated patients was recorded in 1990 when 42 patients were dialyzed. In the following years until 2001 the figures were between 40 and 58, and in 2001 55 new patients were treated. In 1966, the mean age of patients undergoing this therapy was 29.5 years, and with time it increased to 40 in 1978. From 1989 on, the mean age rose to 50, and from 1998 to 60. In 2001, the mean patient age was 63.2 years. The primary renal diseases that led to uremia in the study population were glomerulonephritis (GN) in 256 (28.1%), pyelonephritis (PN) in 165 (18.1%), diabetes mellitus (DM) in 161 (17.7%), nephrosclerosis in 111 (12.2%), uremia after transplanted kidney rejection in 47 (5.2%), polycystosis in 40 (4.4%), lupus nephritis in 12 (1.3%), other causes in 89 (9.7%), and unknown cause in 24 (2.6%) patients. The distribution of primary renal disease during the observed period was as follows: from 1966 till 1979 the cause of uremia was GN in 88 (62%), PN in 30 (21.1%), DM in only 1, polycystosis in 3, post-transplant uremia in 7, lupus in 3, and other causes in 7 patients. From 1980 to 1989, GN was the cause of uremia in 67 (31.6%), PN in 45 (21.2%), DM in 22 (10.4%), nephrosclerosis in 26 (12.3%), polycystosis in 11 (5.2%), post-transplantation uremia in 12 (5.7%), lupus nephritis in 8 (3.8%), other causes in 17 (7.9%) and unknown cause in 3 (1.9%) patients. During the 1990-2001 period, GN was recorded in only 101 (18%), PN in 90 (16.2%), DM in 138 (24.9%), nephrosclerosis in 82 (14.7%), polycystosis in 26 (4.7%), post-transplantation uremia in 28 (5.0%), lupus nephritis in 6 (1.1%), other causes in 65 (11.7%) and unknown cause in 20 (3.6%) patients. The mortality was caused by cardiac disease in 50.4%, cerebrovascular disease in 14.8%, infectious disease in 13.2%, malignancy in 7.5%, high potassium in 5.1%, gastrointestinal disease in 3.5%, other vascular diseases in 1.6%, cachexia in 1.3%, loss of blood access in 0.8%, other reasons in 1.1% and unknown reasons in 0.5% of patients. The results clearly indicate that the number of new patients grew and the mean patient age increased every year. Diabetes mellitus was the leading cause of uremia while GN and PN were less common. The main causes of death were cardiovascular diseases.
