Exchange/retrograde ureteral stent set.
Once in position, ureteral stents are relatively inaccessible. A ureteral stent set was developed that allows for retrograde study of the collecting system or exchange of the stent with or without the assistance of a cystoscope. This has proved to be useful for opacification of the collecting system during extracorporeal shock wave lithotripsy or percutaneous nephrolithotomy, or after ureteroscopy.
