The impact of clinically insignificant residual fragments following endourological management of urolithiasis: a systematic review of complications and re-intervention rates

Patients with CIRF≤4 mm should be monitored closely and informed about the non-neglectable likelihood of complications and of re-intervention. On the other hand, they have one probability out of three of spontaneous passage. Endourologist and patients should be aware of these outcomes to better plan the management, follow-up, and the "insignificant" nature of residual fragments. Hence, the aim of surgeries should be achieving the complete SFS, especially in high-risk stone former patients.
