Purpose: We determined gender differences in the symptomatic presentation of kidney and ureteral stones among the Hispanic population and compared it with presentation in the Caucasian population.

Patients and Methods: A retrospective chart review was performed on 443 patients seen in our Emergency Department or Urgent Care Center for symptomatic kidney or ureteral stones over a 5-year period. Demographic information was obtained, including sex, race, age, location of stone, stone size, and type of urologic intervention. Of the 443 patients, 263 (59%) were Hispanic, and 180 (41%) were Caucasian.

Results: The male-to-female ratio of the symptomatic patients with kidney stones was 1.48 for both Hispanic and Caucasian patients. The male-to-female ratio for ureteral stones was 1.06 and 2.48 for the Hispanic and Caucasian patients, respectively (P < 0.05). The rate of urologic intervention was similar among Caucasian males and females and Hispanic females (approximately 33%) but significantly lower among Hispanic males (18%).

Conclusions: The relative symptomatic presentation of ureteral stones of men and women among the Hispanic population is nearly 1:1, whereas the ratio in Caucasian men and women approaches the previously reported 2.5:1. No significant racial or sex differences were noted in the symptomatic presentation of kidney stones. In comparison with Hispanic men, Hispanic women undergo significantly more urologic interventions for symptomatic urolithiasis.
