1) 1985年の尿路結石の発生率は松阪地区で最も高かったが市部郡部別には差は認めなかった.季節的には夏期,特に8月,9月に高率であった.2)上部尿路結石が96.9%で,三重県南部では下部尿路結石の比率が高い傾向が見られた.3)平均年齢は44.5歳で,40歳代～50歳代にピークが見られた.4)手術的治療法としてPNL(経皮的腎尿管結石摘出術),ESWL(体外衝撃波結石破砕法)が新しく加わり,全体の中でも重要な位置を占めている.5)結石成分はカルシウム結石が84.0%と最も多かったTo determine the present status of urolithiasis in Mie Prefecture, we analyzed the 1,314 patients of urolithiasis at 17 Departments of Urology and 2 Departments of Medicine in 1985. The ratio of male patients to female patients was 2.6 to 1. The most frequent incidence of urolithiasis was observed in Iinan county. The incidence of urolithiasis in the urban area was the same as that in the country. Most of the stones (96.9%) were in the upper urinary tract. The incidence of lower urinary tract calculi tended to be high in southern Mie Prefecture. The ratio of upper urinary tract calculi to lower urinary tract calculi in the urban area was the same as that in the country. The peak incidence in males was in the forties, while that in females was in the fifties. The average age was 44.5 years old. Ureterolithotomy was the most frequent (37.5%) surgical therapy, percutaneous nephrolithotomy and shock wave lithotomy done in 8.0% and 6.3%, respectively. The most frequent component of the urinary tract calculi was calcium oxalate and/or calcium phosphate (84.0%). The incidence increased in summer (April through September).
