Summary

Residual stone fragments are common following definitive treatment of renal or ureteric stones. Studies on the natural history of remaining fragments following shock-wave lithotripsy (SWL), percutaneous nephrolithotomy or ureterolithotripsy indicate that the term clinically insignificant residual fragments could be a misnomer. Every effort should be made to ensure a stone-free status following treatment. Recent advances in technology have been highly effective in preventing residual fragment creation. Accurate post-procedural identification of residual stones is mandatory, with computed tomography being the more sensitive diagnostic modality. Surgical management in the form of a repeat SWL, second-look flexible nephroscopy or ureterorenoscopy may be needed for the management of remaining stones. Medical therapy may control active stone formation, reduce growth or agglomeration, and increase the clearance rate of residual fragments.
