We have analyzed the cases of urolithiasis during the seven years' period after the opening of our clinic, from November 28, 1977 to December 31, 1983.
1) The total number of out-patients was 6265, of whom 527 (8.4%) had urinary calculi.
2) The ratio of males to females in these stone patients was 3.0:1.
3) Of the 527 patients with urolithiasis, 240 patients (45.5%) had ureteral stones, whereas 213 patients (40.4%) renal calculi.
4) The peak incidence age of urinary stone was the third and forth decades.
5) The seasonal incidence of out-patients with ureteral stone was maximum in summer.
6) The overall rate of spontaneous passage of ureteral stones was 48.3% (116/240).
7) The total number of operations for urolithiasis was 186 during this period and removal of parathyroid lesions was performed in 19 cases.
8) Analysis of the composition of the calculi revealed that calcium oxalate mixed with calcium phosphate was encountered most frequently.
