PURPOSE: We have previously shown that nonwhite patients with ureteropelvic junction obstruction undergo pyeloplasty at a younger age than white patients. The mechanisms behind this finding are unclear, since there is no known racial variation in the natural history of ureteropelvic junction obstruction. We used a detailed clinical database to explain this phenomenon. MATERIALS AND METHODS: We retrospectively reviewed all patients undergoing primary pyeloplasty at our institution between 1992 and 2008. More than 360 data points were abstracted for each patient, including self-reported race, socioeconomic status, symptom duration and presentation. RESULTS: Of 847 patients undergoing pyeloplasty during the study period 741 met inclusion criteria. Nonwhite patients underwent surgery at a younger age (0.6 years) than whites (2.6 years, p <0.0001). When stratified by timing of clinical presentation (prenatal vs postnatal), there was no significant difference in race among patients presenting prenatally (0.37 vs 0.36 years, p = 0.22). Nonwhite patients presenting postnatally were significantly younger than white patients (6.3 vs 8.2 years, p = 0.03). This finding appeared to be due to differences in age at initial clinical presentation (5.4 vs 7.0 years, p = 0.03) and in time from initial clinical presentation to urological evaluation (0.6 vs 3.2 months, p = 0.03). These differences persisted after correcting for other factors, including markers of socioeconomic status. CONCLUSIONS: Consistent with previous studies, we found that nonwhite patients underwent primary pyeloplasty at a younger age than whites. This difference is limited to patients presenting after birth. Prenatally diagnosed patients underwent surgery at similar ages regardless of race. Copyright Â
