Systemic Inflammatory Response Syndrome After Flexible Ureteroscopic Lithotripsy: A Study of Risk Factors

We recommend that the length of lithotripsy be well controlled in patients with large stone burden and struvite calculi. Staging procedures are also required. Additionally, irrigating with a low flow rate and low pressure and using a large-caliber UAS for better drainage are required to keep a low renal pelvic pressure during FUL procedures.
