Insights
Urinary stone formation in children shares similarities with adults but is significantly influenced by recurrent infections and urinary tract malformations. Early diagnosis and tailored metaphylaxis are crucial for reducing recurrence rates in pediatric patients.
Area of Science:
- Pediatric Nephrology
- Urology
- Metabolic Disorders
Context:
- Urinary stone incidence in children is 3-5% globally, but higher in underdeveloped countries (approx. 30%).
- Diagnosis often occurs by school age, with a shift towards upper urinary tract stones and increased oxalate-containing stones.
- Recurrence rates for pediatric urinary calculi range from 15-25%.
Purpose:
- To analyze the specific factors relevant to urinary stone formation in children.
- To discuss diagnostic approaches, including identifying malformations and metabolic disturbances.
- To present modern treatment modalities and the importance of metaphylaxis.
Summary:
- Pediatric urinary calculi share formation principles with adults, but recurrent urinary tract infections and congenital malformations are key factors.
- Diagnostic evaluation must focus on urinary tract abnormalities and metabolic issues to guide effective metaphylaxis.
- Modern treatments like extracorporeal shock wave lithotripsy and ureterorenoscopy are effective, but metaphylaxis is vital for preventing recurrence.
Impact:
- Highlights the importance of early and comprehensive diagnosis in pediatric urolithiasis.
- Emphasizes the role of tailored metaphylaxis in reducing long-term stone recurrence.
- Provides insights into current therapeutic strategies for pediatric urinary stones.
Abstract:
Principally the formation of urinary calculi in children is not very different from that of grown-ups. For children some factors, however, are of special relevance namely recurrent urinary tract infections and malformations in the area of the urinary tract. In western countries nowadays the incidence rate of urinary stones in children is 3-5% of all patients suffering from this disease, in the underdeveloped countries we have rates of about 30%. A clear sex preference in children wasn't found, the age distribution shows that for half of the children suffering from calculi, diagnosis has been made until they've reached school age. Stone localisation is shifting towards the upper urinary tract, in the past we had mainly urinary bladder stones. Concrements containing oxalate are being found more often today. For children we have a high proportion of mixed concrements. The rate of recurrence for children is 15-25%. Diagnostically we have to search out especially for malformations respectively obstructions of the urine flow, disturbances in metabolism in consideration of metaphylaxis possibilities, however, must not be taken out of account either. Promotory and inhibitory factors of stone formation are presented and their significance is explained by means of selected cases of our own patients. Modern techniques of operative resp. instrumental removal of urinary calculi are presented, especially the relevance of modern strategies as e.g. the extracorporal shock wave lithotripsy, percutaneous litholapaxy and ureterorenoscopy are discussed. Adequate metaphylaxis (general, dietetic, medicamentous) can lower the rate of recurrence of stone formation. This is only possible, however, on condition of a consequent diagnosis to find possible causes of stone formation to be able to choose the right measures of metaphylaxis.
