Insights
Early detection of vesicoureteric reflux (VUR) in children has improved, particularly in females, following updated guidelines. However, earlier diagnosis in boys remains a priority to prevent kidney damage.
Area of Science:
- Pediatric Nephrology
- Urology
- Diagnostic Imaging
Background:
- Vesicoureteric reflux (VUR) can lead to kidney scarring and damage if not detected early after urinary tract infections.
- Guidelines recommend prompt VUR detection to mitigate secondary renal damage in children.
- Implementing these recommendations is crucial for improving patient outcomes.
Purpose of the Study:
- To assess the practical implementation of VUR detection guidelines.
- To evaluate the impact of these guidelines on the age of VUR diagnosis.
- To compare current VUR diagnosis ages with historical data and international benchmarks.
Main Methods:
- Retrospective analysis of 126 patients diagnosed with VUR between 1976 and 1999 at a Milan tertiary center.
- Comparison of diagnostic age data with a historical cohort of 102 patients from Melbourne (1946-1970).
- Statistical analysis to determine significant differences in age at diagnosis based on birth year and gender.
Main Results:
- Median age of VUR diagnosis significantly decreased from 34 months (pre-1988) to 8 months (post-1988) in Milan.
- This trend was more pronounced in females than males.
- Milan's current diagnosis ages (<1 year for boys, 1-2 years for girls) are significantly earlier than Melbourne's historical data (1-2 years for boys, 5-6 years for girls).
Conclusions:
- VUR diagnosis in Milan has become significantly earlier over time, especially post-1988.
- While improvements are noted, particularly in females, earlier diagnosis in boys remains an area for focus.
- The study highlights successful guideline implementation and the need for continued vigilance in pediatric VUR management.
Aim:
Efforts are currently made to detect vesicoureteric reflux (VUR) early after urinary infections in order to limit secondary renal damage. This study investigated the extent to which recommendations for the detection of VUR are put into practice, and their influence on the age at diagnosis.
Methods:
The age at diagnosis of VUR after urinary tract infections was analysed in 126 patients (48M, 78F) referred to a tertiary centre in Milan between 1976 and 1999.
Results:
The median age at diagnosis was 34 mo in subjects born before and 8 mo (p < 0.001) in those born after 1988. The difference was statistically significant in female but not in male subjects. The figures from Milan were compared with those for 102 patients (35M, 65F) born between 1946 and 1970, treated in Melbourne and reported in 1976. In Melbourne the median age at diagnosis was 1-2 y for boys and 5-6 y for girls; in Milan, the corresponding figures were <1 y and 1-2 y. The difference between Melbourne and Milan was statistically significant for both genders.
Conclusion:
In Milan VUR is now detected earlier than in the past. This trend is more marked in females than in males, but reflux is still detected earlier in boys.
