Renal Stone Recurrence Risk Assessment

Identifies risk factors for renal stone recurrence to guide metabolic evaluation and preventive treatment.

Result

There is no published points score for stone recurrence. The EAU urolithiasis guideline classes a patient as a HIGH-RISK stone former if any risk factor is present: early onset (especially children and teenagers), family history, recurrent stones (short interval since the last), brushite, uric acid/urate or infection stones, a solitary kidney, chronic kidney disease; diseases linked to stones (e.g. hyperparathyroidism, nephrocalcinosis, malabsorption or bariatric surgery, sarcoidosis); genetic causes (cystinuria, primary hyperoxaluria, renal tubular acidosis type 1); drug-induced stones; or anatomical abnormalities (e.g. medullary sponge kidney, pelvi-ureteric junction obstruction, horseshoe kidney). High-risk formers need stone analysis and specific metabolic evaluation (blood tests and 24-hour urine); others need general preventive advice (high fluid intake, balanced diet) and stone analysis.
