The incidence of urolithiasis was 147/100,000 population in 1991. The highest incidence was found in pactients in their 50s. The male to female uatio was 2.9:1. There were 895 cases with single stones, and 289 cases with multiple stones. The ratio of upper to lower urinary tract stones was 13.6 :1. Among the hospitalized patients. 673 cases (56.8%) received surgical treatment and 511 cases (43.2%) received conservative treatment with spontaneous stone passage. Among 1071 cases of upper urinary tract calculi , 567 cases(52.9%) received surgical treatment : 236 cases (41.6%) were treated by endoscopic surgery, 176 cases (31.0%) were treated by open- surgery and 131 cases (23 .1%) by extracorporeal shock wave lithotripsy. Among 79 cases of lower urinary tract calculi. 75 cases (94.9%) were treated surgically: 68 cases (90.7%) by transurethral endoscopic surgery and 7 cases (9.3%) by cystolithotomy.

Stone patients increased in number during the summer season (July and August). Systematic questionnaires completed by the patients with urolithiasis. lead us to the following conclusions: 1) 50.7% (216/438) of patients gave a past history of urolithiasis, and 2. family histories show that males whose siblings have urolithiasis were at the highest risk of uolithiasis, followed by those whose fathers had a history of urloithiasis.#0088#en-US
