Metabolic Stone Team
Once patients have formed a kidney stone they have a significant risk of forming stones in subsequent years. Overall, half of patients will form another stone within 5 years and 70% within 10 years. Simple preventative measures can reduce this risk for most patients, however some patients have an underlying condition that predisposes them to stones. Some of these are rare genetic causes (e.g cystinuria) others are more common (e.g. hypercalciuria). Evaluation and treatment of such patients can reduce the risk of recurrence.
The role of the metabolic stone team is to evaluate high risk patients and to provide tailored treatment to try and prevent future episodes.
High risk patients that require further evaluation include:
- highly recurrent stones (≥ 3 stones in 3 years)
- infection stones
- patients with uric acid stones
- all children with stones
- patients with a genetically determined cause of stones
- patients forming brushite stones
- patients with hyperparathyroidism
- patients with gastrointestinal diseases
- patients with residual stone fragments
- Patients with nephrocalcinosis
- patients with a strong family history of stones
