Insights
Pediatric kidney stone operations show a shift in gender distribution across age groups, with more older females undergoing surgery. However, overall demographic trends remained stable between 2016 and 2020.
Area of Science:
- Pediatric Urology
- Health Services Research
- Epidemiology
Background:
- Pediatric kidney stone incidence is rising, necessitating updated analyses of surgical trends and patient demographics.
- Previous studies lack recent data on the demographic factors influencing pediatric urologic stone operations.
Purpose of the Study:
- To examine temporal trends in pediatric urologic stone operations from 2016 to 2020.
- To identify demographic risk factors associated with pediatric kidney stone surgeries.
Main Methods:
- Utilized the Florida Healthcare Cost and Utilization Project (HCUP) dataset.
- Analyzed data for 888 pediatric patients (≤17 years) undergoing urologic stone operations between 2016-2020.
- Assessed demographic characteristics (sex, age, race/ethnicity) and operation year.
Main Results:
- No significant changes in patient proportions by sex or race/ethnicity over the study period.
- A notable shift in gender distribution by age: males decreased from 71.1% (0-1 yrs) to 36% (16-17 yrs), while females increased from 28.9% to 64.0%.
- Ureteroscopy was the predominant surgical procedure for pediatric urolithiasis across all age groups.
Conclusions:
- Significant age-related differences in race and gender distributions were observed in pediatric kidney stone surgery patients.
- Despite age-specific demographic variations, the overall demographic composition of patients undergoing these operations showed no significant trend changes during the study period.
Introduction:
Pediatric kidney stone incidence has risen over the years, but recent analyses of trends and surgical demographics are lacking. This study examined the trends and demographic risk factors pertaining to pediatric patients undergoing kidney stone operation.
Methods:
The Healthcare Cost and Utilization Project (HCUP) dataset for the state of Florida, which includes all emergency department visits, inpatient admissions, and ambulatory surgeries and services, was utilized. We extracted data for patients 17 years or younger with urolithiasis who underwent urologic stone operations between 2016 and 2020. The proportion of pediatric patients undergoing urologic stone operations was measured based on demographic characteristics and the operation year.
Results:
There were 888 pediatric patients who underwent urologic stone operations between the years 2016 and 2020. No significant change was found across the years in the proportions of patients by sex or race/ethnicity. Across the different age groups, the proportion of males undergoing urologic operations decreased from 71.1% in the 0-1 age group to 36% in the 16-17 age group, while the proportion of females with urologic operations increased from 28.9% in the 0-1 age group to 64.0% in the 16-17 age group (<0.001). There was a significant difference across the different age groups in the proportion of patients undergoing operation by race (0.035). Ureteroscopy was the most utilized operation for urolithiasis in pediatric patients across all age groups.
Discussion:
Significant differences in the distribution of race and gender are observed among patients undergoing kidney stone operations across different age groups. However, when examining trends over the study period, there were no significant changes in the overall demographic composition of patients undergoing these surgeries.
