OBJECTIVE: Our goal was to establish the clinical presentation and features of @entity158 attacks in @entity1 with recurrent @entity490 (RAP) and @entity1791 . METHODS: We compared the rate of previous appendectomy among 100 consecutive @entity1 with that of 270 control subjects. We also compared the frequency of @entity158 attacks with that reported by @entity1 with functional or organic gastrointestinal RAP. RESULTS: Fifty-three @entity1 had no history of @entity3833 or gross @entity811 , and only 35 had @entity811 at the first visit; 41 @entity1 were evaluated for @entity1791 only because of a family history of @entity1290 associated with RAP. Twenty-nine @entity1 had been previously hospitalized for abdominal symptoms. Sixteen @entity1 and 4 control subjects (1.5%) had undergone a previous appendectomy (P < .0001). Two to 28 months before the diagnosis of @entity1791 , 37 @entity1 underwent abdominal ultrasonography, which did not show urinary stones. Sixty-nine percent of subjects younger than 8 years of age had central/diffuse @entity490 . The mean frequency of @entity158 attacks was 4 to 9 times lower than in @entity1 with functional or organic gastrointestinal RAP. CONCLUSIONS: Because of the inconstant occurrence of @entity3833 and @entity811 , the location of @entity158 in areas other than the flank, and the lack of calculi shown on imaging studies performed after @entity158 attacks, the urologic origin of @entity158 may be overlooked and ineffective procedures performed. The possibility of @entity1791 should be considered in @entity1 with RAP who have a family history of @entity1791 and/or infrequent @entity158 attacks, even when @entity3833 and @entity811 are lacking, and in younger @entity1 even when @entity158 is not lateral.
