Ureteroscopic removal of stone (URS)

Urinary stones present in the ureter, particularly hard stones or stones that cannot be treated with ESWL, can be treated using laser. Ureteroscopic removal of stone or URS is a procedure which is used to treat stones situated in the middle and lower ureter. This procedure is performed under general OR SPINAL anesthesia.

A ureteroscope or a small, fiberoptic instrument is inserted through the urethra and bladder into the ureter. The ureteroscope enables the urologist to directly visualize the stone present in the ureter.

While small stones are removed using a specialized stone basket, large stones are disintegrated using a laser or a similar device. A stent may be placed in the ureter for some days following the treatment in order to facilitate healing and prevent blockage caused by inflammation or spasm. Stent is usually removed 8-10 days after surgery using flexible cystoscope as an outpatient procedure.
