Pdf Summary

This study aimed to compare urodynamic parameters between different racial/ethnic groups in patients with overactive bladder (OAB) symptoms. The study consisted of a retrospective chart review of 166 patients who underwent urodynamic studies (UDS) at an urban academic urogynecology clinic. The results indicated that there may be racial differences in UDS parameters among patients with OAB symptoms, but the limited sample size, especially for the White race, limits the applicability of the data. <br /><br />Some notable findings include: <br />- African Americans are more likely than Hispanics to present with an initial complaint of dry OAB, while Hispanics are more likely than African Americans to complain of mixed urinary incontinence. <br />- There is a trend suggesting that African Americans have more detrusor overactivity (DO) on UDS than Whites. <br />- Both Blacks and Hispanics have lower volumes at the point of "strong desire" during UDS compared to Whites. <br />- There were no significant differences between race/ethnicities in leakage during DO, volume of first occurrence of DO, postvoid residual, or other UDS parameters. <br /><br />This study adds to the existing literature that has noted racial differences in pelvic floor disorders and OAB symptoms. It is important to note that the results of this study are limited by the sample size and the lack of inclusion of potential confounders such as comorbidities and previous pelvic surgery. Further research with larger and more diverse samples is needed to better understand the racial/ethnic differences in urodynamic parameters in patients with OAB. The authors declared no financial disclosures.
