What are the risks of minimally invasive ureteroscopic lithotripsy?

All operations are risky. The biggest risk of this operation is to damage the ureter. If it is mucosal injury, perforation, and mucosal sleeve avulsion, it is not a big problem, but if it is a whole layer of rupture, it needs laparotomy. In addition, there are stone fragments falling back into the renal pelvis, stone residues, failure to enter the mirror, acute renal function injury and so on. In addition, after this operation, D-J tube should be placed in ureter for 2 weeks 1 month, and then taken out by cystoscope, which may cause discomfort during indwelling and extubation.
