在日本兵库县北方的田岛地区，只有两所综合医院设有泌尿科，通过以医院为基础的队列研究，评估了15年间上尿路结石发病率的时间趋势。由于交通网络和地理环境的隔离，田岛地区几乎所有的泌尿系统结石患者都被转介到这两家医院。2005年至2007年期间，两所医院的放射学证实的上尿路结石患者被纳入本研究。调查包括年龄和性别、结石位置、泌尿系结石史、接受的治疗和结石成分（如果有的话）。利用日本2005年人口普查数据估计上尿路结石的年发病率，并与田岛1991-1993年的数据进行比较。本研究纳入了1，305例患者。在1991-1993年期间，男性和女性的经统计学校正的发病率（+/-95%CI）分别为157（+/- 22.4）和57（+/- 12.6），而男性和女性的发病率分别为141（+/- 20.7）和63（+/- 13.4）。总的来说，30.7%的患者接受了包括冲击波碎石术、内镜碎石术和开放手术在内的介入治疗，而1991-1993年为25.3%。草酸钙/磷酸钙结石89.6%，鸟粪石4.5%，胱氨酸结石1.0%，尿酸结石4.0%，其他1.0%。在田岛地区，15年来上尿路结石的发病率没有变化。
Time trend of incidence of upper urinary tract stone during 15 years was evaluated by hospital-based cohort study in Tajima area, northern part of Hyogo prefecture, Japan, which has only two general hospitals with Department of Urology. Due to isolation in terms of traffic network and geographic circumstances, almost all patients with urinary stone in Tajima area are referred to the two hospitals. During the period 2005-2007, patients of the two hospitals with radiologically proven upper urinary tract stone were included in this study. The survey included the age and gender, location of stones, history of urinary stone, treatment received, and stone composition, if available. Annual incidence of upper urinary tract stone was estimated using the data of population census of Japan 2005 and compared with the data of Tajima during 1991-1993. 1,305 patients were included in this study. Age-adjusted incidence (+/- 95% CI) was 157 (+/- 22.4) for men, and 57 (+/- 12.6) for women, compared with 141 (+/- 20.7) for men, and 63 (+/- 13.4) for women during 1991-1993. In total, 30.7% of patients received interventional treatment including shock wave lithotripsy, endoscopic lithotripsy and open surgery, whereas 25.3% in 1991-1993. Calcium oxalate/phosphate stone was 89.6%, struvite stone was 4.5%, cystine stone was 1.0%, uric acid stone was 4.0%, and others were 1.0%. In Tajima area, incidence of upper urinary tract stone has not changed during 15 years.
