A third
type of procedure, called Uretero Reno Scopy (URS), allows
treatment of stones in the mid and lower parts of the ureter.
A thin endoscope, called an Uretero Reno Scope is inserted
through the urethra (without an incision) into the bladder
and ureter. The stone can then be removed via a cage-like
instrument (stone basket) or shattered with an ultrasonic
probe or laser. This procedure also allows for the option
of pushing the stone back into the kidney from where ESWL
can be performed better. A stent may be left in the ureter
for a few days until the reaction to the instrumentation
subsides.
