Aging and UTI: are Teenagers more prone?

Background: None of the studies have classified UTI in males and females based on the age factor. Therefore the present study compared the prevalence of UTI in various age groups of males and females.

Methodology: Dipstick and microscopy urinalyses were carried out on 1569 consecutive urine samples of patients, and the results were statistically analyzed.

Results: UTI in females was more often than males, excluding children (p=0.27) and adults (p=0.30), groups. When compared within females, UTI was more prevalent in teenagers and old groups (p<0.01). Pyuria was significantly higher in all age groups of females except children (p=0.21) in comparison to age-matched males. Both young females and males had a significantly low prevalence of glycosuria and proteinuria when compared within the same-sex groups. We discovered that there are 56% chances of having pyuria, 26% chances of proteinuria, and 11% chances of glycosuria and hematuria in UTI patients with negative predictive value of more than 90%. This study also showed that 21% of glycosuric patients were positive for proteinuria (glomerular disease), which showed increased chances of progression to glomerular disease in these patients. 

Conclusion: UTI within and in between males and females at different ages are significantly different. Teenagers and old groups are more prone to dvelop UTI. UTI negative patients have <10% chance of having glomerular disease, hematuria and pyuria.
