Abstract
Background. The aetiological spectrum of acute renal failure (ARF) has changed in developed countries. It was the purpose of the study to evaluate whether similar changes have occurred in this part of the world as well. Methods. In a prospective study a total of 439 patients with ARF were evaluated. They had been admitted to one hospital during two successive periods, i.e. 1983–1990 and 1991–1997. Results. Of 439 patients with ARF, 116 were admitted in 1983–1990 (first period) and 323 in 1991–1997 (second period). The age of presentation increased from 49.8±6.2 years in the first period to 58.8±16.4 years in the second. Medical causes were present in 259 cases (59%), surgical causes in 110 cases (25%), and obstetric causes in 70 cases (16%). The frequency of surgical cases decreased from 28.4% in the first period to 23.8% in the second period. The respective figures for obstetric cases were 18.9% and 14.8%. Mortality did not change with time (33.6% in the first and 31.0% in the second period); the overall mortality was 31.7%. The mortality was higher for surgical (45.5%) than for obstetric (27.8%) and medical ARF (24.3%). Conclusion. In the mid-1970s, the most common causes of ARF in Turkey were obstetric complications and septic abortion. The aetiological spectrum of ARF has changed and today medical causes predominate. ARF resulting from septic abortion has become rare, possibly because of liberalization of abortion in 1983 in Turkey.
