Insights
Urinary tract infections are a significant cause of urolithiasis in children, with Proteus species being a common culprit. Recurrent infections were frequently linked to Pseudomonas aeruginosa and Klebsiella species.
Area of Science:
- Pediatric Nephrology
- Urology
- Microbiology
Background:
- Urolithiasis in children presents unique etiological challenges.
- Understanding the causes and associated infections is crucial for effective management.
Purpose of the Study:
- To analyze the causes of urolithiasis in pediatric patients.
- To investigate the prevalence and types of urinary tract infections (UTIs) associated with childhood urolithiasis.
Main Methods:
- Retrospective analysis of 100 pediatric urolithiasis cases treated between 1976-1979.
- Bacteriological investigations of urine samples at diagnosis and during follow-up.
- Bacteriological analysis of removed stones in select cases.
Main Results:
- Infection-induced stones were the most common cause (31%), followed by metabolic (26%) and idiopathic oxalic lithiasis (17%).
- Urinary tract infections were detected in 57.4% of children at diagnosis, with Proteus sp. being the most frequent pathogen.
- During a 3-year follow-up, recurrent UTIs were common, with Pseudomonas aeruginosa, Klebsiella sp., Proteus sp., and E. coli being the predominant bacteria.
Conclusions:
- Infection is a primary driver of pediatric urolithiasis.
- Effective management requires addressing both stone disease and underlying/recurrent urinary tract infections.
- Bacteriological analysis of stones can be valuable in identifying infectious etiologies.
Abstract:
100 cases of urolithiasis in children treated in Pediatric Clinic of National Research Institute of Mother and Child in the period of 1976-1979 were analized . In 93 children the cause of urolithiasis was established. The most of them (31%) are cases of infection induced urinary stones. Among other reasons of urolithiasis the most common are: metabolic reasons in 26%, probably metabolic reasons in 13%, idiopathic oxalic lithiasis in 17% and others in 6%. At the moment of urolithiasis diagnosis in 94 children bacteriological investigations were done. In 54 cases, i.e. 57,4% infections of the urinary tract were found. 57,8% of boys and 62,2% of girls had urinary tract infections. The most frequent bacteria was urease producting Proteus sp. During 3 years of observation urinary tract infections in 67 children were found. Among bacteria causing the reinfections the most frequent were: Pseudomonas aeruginosa (25,4%), Klebsiella sp. (22,4%), Proteus sp. (19,9%) and E. coli (15%). In 9 cases the bacteriological analysis of removed stones were done. In 2 cases bacteria causing the infection were isolated from the stones, since they were not present in urine any more.
