Summary
This 15-year study of 2086 patients reveals calcium stones are most common. Recurrence affects 50%, with metabolic defects found in many idiopathic calcium stone cases.
Area of Science:
- Nephrology
- Urology
- Biochemistry
Background:
- Kidney stones (nephrolithiasis) are a significant health issue.
- Understanding the epidemiology and etiology of different stone types is crucial for effective management.
- Previous studies highlight variations in stone prevalence, demographics, and underlying causes.
Purpose of the Study:
- To comprehensively analyze the characteristics of kidney stones in a large patient cohort.
- To determine the prevalence, recurrence rates, and etiological factors of various kidney stone compositions.
- To investigate demographic variations and age of onset for different stone types.
Main Methods:
- Retrospective analysis of 2086 consecutive patients over 15 years.
- Comprehensive biochemical investigations for all patients.
- Categorization of stones by type: calcium, infection (struvite), uric acid, calcium oxalate, and cystine.
Main Results:
- Calcium stones were most prevalent (61%), followed by infection stones (24%).
- Nephrolithiasis was more common in males, while infection stones were more frequent in females.
- 50% of patients experienced stone recurrence, with cystine and uric acid stones showing the highest recurrence rates.
- Metabolic defects were identified in 54% of idiopathic calcium stone patients, including 33% with hypercalciuria.
Conclusions:
- Calcium stones are the predominant type, with significant recurrence rates.
- Diverse etiological factors, including metabolic defects and infections, contribute to stone formation.
- Tailored diagnostic and treatment strategies are essential based on stone type and patient-specific risk factors.
