Urinary lithiasis in childhood in the Bristol clinical area
Insights
This study on childhood urinary calculi in Bristol found anatomical, metabolic, or infective causes in most cases. A potential link between hard, alkaline water and stone formation was suggested.
Area of Science:
- Pediatric Nephrology
- Urology
- Environmental Health
Background:
- Urinary calculi (kidney stones) in children present unique diagnostic and etiological challenges.
- Understanding the contributing factors is crucial for effective management and prevention strategies.
Purpose of the Study:
- To analyze the characteristics and underlying causes of urinary calculi in a pediatric cohort.
- To investigate potential environmental associations, specifically water quality, with stone formation.
Main Methods:
- Retrospective review of 59 consecutive pediatric urinary calculi cases treated between 1950 and 1973 in Bristol.
- Classification of etiological factors including anatomical, metabolic, and infective abnormalities.
- Analysis of local water supply characteristics (hardness, alkalinity).
Main Results:
- Peak incidence observed in the 2nd-3rd years of life, with a secondary peak at age 10.
- Identified causes: anatomical (39%), infective (29%), metabolic (8.5%), with 22% classified as idiopathic.
- Overall recurrence rate of 7%, reduced to 3.5% excluding cystinuria cases.
- Tentative association noted between stone formation and residence in areas with hard, alkaline water (pH > 8).
Conclusions:
- Childhood urinary calculi have diverse etiologies, often multifactorial.
- Environmental factors, particularly hard and alkaline water, may play a role in stone development.
- Further research into water quality and pediatric stone disease is warranted.
Abstract:
A series of 59 consecutive cases of urinary calculi in childhood is presented, being acquired from one local area (Bristol). These children were treated from 1950 to 1973. The peak presentation was in the 2nd and 3rd year of life, with a secondary peak in the 10th year. Anatomical (39%), metabolic (8.5%) or primary infective abnormalities (29%) were demonstrable, but 22% had to be left in an unsatisfactory "idiopathic classification". The overall recurrence rate of 7% was reduced to 3.5% when those patients with cystinuria were excluded. The local water supply areas have been studied and a tentative association is suggested between patients and their environment when they live in an area where the water is not only hard but also alkaline (pH greater than 8).
