Kidney Int · 2021 · Meta-analysis / systematic review
Cystinuria: clinical practice recommendation

Conclusion: Because of the rarity of the disease and the poor level of evidence in the literature, these statements could not be graded. This clinical practice recommendation provides guidance on all aspects of the management of both adults and children with cystinuria, including diagnosis, surgery, and medical treatment.

Cochrane Database Syst Rev · 2015 · Meta-analysis / systematic review
Citrate salts for preventing and treating calcium containing kidney stones in adults

Conclusion: Citrate salts prevent new stone formation and reduce further stone growth in patients with residual stones that predominantly contain oxalate. The quality of reported literature remains moderate to poor; hence a well-designed statistically powered multi-centre RCT is needed in order to answer relevant questions concerning the efficacy of citrate salts.
