This study sought to characterize @entity1 with @entity5720 seen at one tertiary referral center by reviewing medical records of @entity1 with a confirmed diagnosis between January 1, 1976 and September 1, 1992. One hundred sixty-five cases were identified. The mean age at diagnosis was 57 yr (SD 15). The female-to-male ratio was 1.1:1.0. Ninety-two percent of @entity1 were white. Seventy-seven percent of cases were unsuspected before diagnosis, and 16% were diagnosed at autopsy. The most common associated conditions were @entity293 , analgesic abuse, @entity5450 , @entity6 , and @entity3458 . There was considerable overlap in the presence of these conditions, with two or more identified in 36% of @entity1 . In addition, 11% of @entity1 had none of these well-recognized risks. Other diagnoses in this group included @entity1988 , @entity2883 , and @entity2791 . A decline in case numbers of approximately 50% was demonstrated over the last 10 yr studied. This period was associated with a 57% reduction in the number of excretory urograms carried out, suggesting that changes in diagnostic imaging preference may have contributed. Vital status and renal outcome data after diagnosis were obtained in 93% of cases. Of those diagnosed while living, survival was lowest among @entity6 @entity1 . Ten-year survival for nondiabetics was not significantly different from the expected survival of an age- and sex-matched cohort. The overall risk for requiring renal replacement therapy after the diagnosis of @entity5720 in surviving @entity1 was low (7% of 136 @entity1 at risk).(ABSTRACT TRUNCATED AT 250 WORDS)
