Abstract
A convertible nephroureteral catheter is used in the treatment of urinary system complications, particularly on the need for a single surgically delivered device to treat patients who must be seen by an interventional radiologist (IR). In many current procedures, patients need to return to the operating room to remove a previously delivered nephroureteral catheter to exchange this catheter with a fully implanted ureteral stent delivered though the same access site at the flank. The present convertible nephroureteral catheter reduces the need to return for a second surgical procedure. Two weeks after initial implantation, the proximal portion of the convertible nephroureteral catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted ureteral stent within the patient's urinary system. Other medical procedures, devices, and technologies may benefit from the described convertible catheter.
