Final answer:
Ureterscopic intervention or placing a stent can be used for stones >10mm.
Step-by-step explanation:
A stone greater than 10mm in size can be treated with ureterscopic intervention or by placing a stent in the ureter.
Ureterscopic intervention is a minimally invasive procedure in which a thin tube with a camera is inserted through the urethra and bladder to the ureter, allowing the doctor to visualize and remove the stone.
Alternatively, a stent can be placed in the ureter to expand it and allow both urine and the stone to pass.
