In order to investigate the therapeutic principles for urolithiasis, patients who had visited our clinic during the 14-year period from January, 1965 to December, 1978 were reviewed statistically. The summary of the present studies is as follows: 1) The ratio of the number of patients with upper urinary tract calculi to the total number of outpatients was 8.2 per cent from 1965 to 1971, whereas from 1972 to 1978, it was increased up to 10.4 per cent. 2) During 1965 to 1971, the largest number of patients was found in the age group of 20-30, whereas from 1972 to 1978, it was found in the age group of 30-40. 3) The ratio of recurrence to whole upper urinary tract urolithiasis was about 20 per cent. 4) The most frequent components of upper urinary tract calculi were calcium oxalate in men (76.0%) and phosphate in women (49.8%). 5) Some causative factors were found in about 40 per cent of patients with upper urinary tract calculi. Main calculogenetic factors were abnormal calcium and uric acid metabolism in men, and urinary tract infection in women.
