You have kidney stones largest is 4cm -2cm your urologist says he needs to do surgery because the tube from the kidney to the bladder is very small what is a shunt?
a piece of metal or stainless steel that is put in the tube (in
this case, the ureter) to keep it open to help pass the stone. But
a stone that large will no doubt not be able to pass thru the
ureter. Usually, lithotripsy to bust it up then the stent to pass
it later. ouch.
