OBJECTIVES: To assess the effects of surgery compared with conservative treatment (no surgery) for @entity459 . DESIGN: Cohort study. SETTING: Nationwide Danish cohort. @entity1 : 3213 @entity1 , mean age 61 (SD 16) years, with a diagnosis of @entity459 between 1980 and 1999. 1934 (60%) underwent surgery and 1279 (40%) were treated conservatively. MAIN OUTCOME MEASURES: Occurrence of @entity174 , @entity170 , kidney or urinary tract stones, @entity583 , @entity951 , @entity943 , @entity101 , @entity712 , @entity64 , acute @entity788 , @entity2275 , @entity925 , @entity5 , @entity146 , and mortality. RESULTS: At diagnosis of @entity459 , @entity1 who subsequently underwent surgery had a lower prevalence of previous @entity174 (odds ratio 0.64, 95% confidence interval 0.51 to 0.80), @entity583 (0.59, 0.42 to 0.83), @entity64 (0.57, 0.37 to 0.88), @entity146 (0.54, 0.31 to 0.94), and @entity925 (0.44, 0.26 to 0.76), whereas @entity1290 (2.49, 1.93 to 3.23) and acute @entity788 (2.77, 1.33 to 5.76) were more prevalent. After diagnosis, the risks of @entity174 (hazards ratio 0.69, 0.56 to 0.84) and @entity2275 (0.59, 0.41 to 0.84) were lower in @entity1 treated surgically than those treated conservatively. Events involving kidney or urinary tact stones were more prevalent in @entity1 treated surgically than @entity1 treated conservatively (1.87, 1.30 to 2.68). Mortality was lower in @entity1 treated surgically (0.65, 0.57 to 0.73). CONCLUSIONS: @entity1 treated surgically for @entity459 have a lower prevalence of @entity174 and @entity2275 than @entity1 treated conservatively. The type of treatment had no effect on the occurrence of @entity65 .
