Olympus LithoStent ureteral stents are unsurpassed in preventing ureteral strictures and urinomas. Their unique grooved design creates a track between the kidney and bladder, enhancing the flow of urine and stone fragments. Made of Tecoflex thermosensitive material, these stents remain firm during placement and soften at body temperature for increased patient comfort. Each stent is supplied with an attached braided nylon tether and one Ramrod metal tip push catheter.
