The UroSurge FilaStent TM Ureteral Stent, has a reinforcing filament which increases its tensile strength, thereby minimizing the probability of the stent breaking during removal. This is in addition to the fact that it will be used for temporary drainage from the ureteropelvic junction to the bladder. Double pigtail stents have been employed to relieve obstruction in a variety of benign, malignant, and post-traumatic conditions. These stents may be placed using endoscopic, percutaneous, or even surgical techniques. The duration of the placement of these stents must not remain indwelling more than twenty-nine (29) days. This product is intended for one-time use only. If the patient's status permits, the stent may be replaced with a new stent.
