Stents must be periodically replaced to prevent fractures within the catheter wall or build-up of encrustation. Stent replacement is recommended approximately every six months; more often in patients who form stones.

Definition
Ureteral stents are thin catheters threaded into segments of the ureter that carry urine, produced by the kidney, either down into the bladder internally, or to an external collection system. Insertion is most often done through the skin (percutaneously); however, in the presence of kidney or ureteral stones, stenting is ideally done during cystoscopy.
