To explore using population-based data the extent to which gender-specific rates of stone disease are changing. Historically, stone disease has been more common among men than women. However, differential changes in dietary intake patterns, fluid intake, and obesity in men and women may cause shifts in stone disease incidence and prevalence.
The State Ambulatory Surgical Database and the State Inpatient Databases were queried for procedures related to renal colic or urolithiasis. Population-based rates of utilization were calculated for the years 1998-2004 by gender. Poisson regression models were fit to measure changes in utilization rates over time.
Of the 107,411 discharges for stone disease, 41,272 (38%) occurred in women. Service utilization increased in both men and women (86.6-105.5 and 42.5-64.4 per 100,000; P <.01 in both). However, the growth rate in women outpaced men (P <.01). Rates of outpatient (57.2-65.8 and 27.0-38.9 per 100,000; P <.01) and ambulatory surgery center utilization (6.4-17.7 and 2.9-9.3 per 100,000 men and women; P <.01) increased significantly in men and women, but inpatient utilization only increased in women (12.5-16.3 per 100,000; P <.01).
Resource utilization for stone disease continues to increase. Most of this increase appears to be due to an increase in disease among women. Increasing obesity, dietary changes, or decreased fluid intake may be contributing to the rapid increase in stone disease treatments in women.
利用基于人群的数据，探讨结石病的性别特定发病率的变化程度。从历史上看，结石病在男性中比女性更为常见。然而，男性和女性的饮食摄入模式、液体摄入量和肥胖的差异变化可能导致结石病发病率和患病率的变化。
查询了州门诊手术数据库和州住院数据库中与肾绞痛或尿路结石相关的手术。按性别计算了 1998-2004 年的人群利用率。采用泊松回归模型来衡量随时间推移利用率的变化。
在 107411 例结石病出院患者中，41272 例（38%）为女性。男性和女性的服务利用率均有所增加（86.6-105.5 和 42.5-64.4/每 10 万人；两者均 P <.01）。然而，女性的增长率超过了男性（P <.01）。门诊（57.2-65.8 和 27.0-38.9/每 10 万人；两者均 P <.01）和日间手术中心利用率（6.4-17.7 和 2.9-9.3/每 10 万人；男女 P <.01）均显著增加，而仅女性的住院利用率增加（12.5-16.3/每 10 万人；P <.01）。
结石病的资源利用率继续增加。这种增加主要是由于女性疾病的增加。肥胖、饮食变化或液体摄入量减少可能是导致女性结石病治疗迅速增加的原因。
