Epidemiología de la litiasis urinaria en nuestra Unidad. Evolución en el tiempo y factores predictivos
OBJECTIVES: To analyze the incidence oflithiasis and stone composition in our setting. The trend iscompared with the results of the majority of studies onurinary calculi reported in the literature based on thenumber and composition of stones.METHODS: The study comprised patients referred tothe Urolithiasis Unit of our hospital over the last 21 years.Stone composition was analyzed by infra-red spectroscopy.The study period was divided into 4 time intervals: 1977-1979, 1977-1980, 1977-1987 and 1977-1998 in order todetermine the trends of the incidence of lithiasis in oursetting.RESULTS: A total of 5516 patients were reviewed; ofthese, 766 had recurrence. The distribution was 385, 995,3378 and 5516, respectively. Calcium oxalate calculishowed an incidence of 61.3%, calcium phosphate 18.5%,uric acid 11.2%, infectious calculi (ammonium urate andammonium magnesium phosphate) 6.6%, and finally theincidence of cisteine calculi was 0.77%. Concerning thedistribution according to sex, 62% of the males hadcalcium oxalate stones, 68% uric acid, 42.5% phosphateand 45% infectious lithiasis. The trends for uric acid,infectious, oxalate and phosphate calculi changed overtime.CONCLUSIONS: There is a clear trend of calculiprevalence in the male, particularly oxalate and uric acidcalculi. There is a trend for cisteine calculi to remain thesame, calcium phosphate and oxalate calculi to increase,and uric and infectious calculi to decrease. The changesobserved may be due to dietary changes and improvementin the quality of life.
