Metabolic Evaluation and Recurrence Prevention for Urinary Stone Patients: An EAU Guidelines Update

Area of Science:

• Nephrology
• Urology
• Metabolic Medicine

Background:

• Urolithiasis is a common condition with a significant risk of recurrence.
• Identifying patients at high risk is essential for effective management.
• Current guidelines aim to standardize diagnosis and treatment for stone recurrence.

Purpose of the Study:

• To define high-risk patients for urolithiasis recurrence.
• To delineate diagnostic and therapeutic algorithms based on stone type.
• To clarify guidelines for preventing stone recurrence.

Main Methods:

• Comprehensive literature search from 1976 to June 2023.
• Systematic review of urolithiasis guidelines.
• Analysis of diagnostic and therapeutic strategies.

Main Results:

• Stone analysis and patient education on fluid, calcium, sodium, and protein intake are fundamental.
• Baseline metabolic screening is recommended for all patients; extensive screening is advised for high-risk calcium stone formers.
• Uric acid, infection, and cystine stones indicate high relapse risk, necessitating close monitoring and targeted therapy.

Conclusions:

• Metabolic evaluation and consistent patient follow-up are critical for preventing urolithiasis recurrence.
• Personalized therapeutic strategies based on stone composition and metabolic screening improve outcomes.
• Long-term monitoring is vital, particularly for patients with poor treatment adherence.
