Observation on the Analysis of Urinary Calculi in Croatia

Background and purpose: The aim of the paper is to present analytical results on the chemical composition of urinary calculi for the 1990-1998 period as well as to compare our results with some literature data from developed Western countries. Materials and methods: 3282 calculi obtained from patients from all parts of Croatia were analyzed by infrared spectrophotometry. Results: The overall ratio of male to female patients was 1.52. The most frequent constituent of the calculi in both sexes were calcium oxalates (~ 74%); phosphates stones were more frequent in female patients, while uric acids were far more frequent in male patients. Conclusions: The obtained results were compared with the literature data from European countries and some considerable differences were not observed. The war years in Croatia caused two increases in sex ratio (male/female patients;) in years 1992 and 1995, but changes in composition of urinary stones were not found.
